Science and Technology Log

The Aloha Station is about 100 miles north of Oahu, Hawaii and was selected because of its closeness to port but distance from land influences (temperature, precipitation etc).  The goal is to select a site that represents the north Pacific, where data can be collected on the interactions between the ocean and the atmosphere. Woods Hole Oceanographic Institution Hawaii Ocean Time Series (WHOTS) has used this site for research since 2004.  You can find real time surface and meteorological data and archived data at the WHOTS website.

We are stationed in the vicinity of mooring 12 and 13 in the Aloha Station to begin intercomparison testing.  CTD (conductivity/temperature/depth) casts are conducted on a regular schedule. This data will help align the data from mooring 12 to mooring 13. If CTDs don’t match up between the two moorings then efforts will be made to determine why.

Mooring 13 is being inspected to make sure sensors are working. Photographs have been taken to determine measurement height of the instruments and where the water line is.

When I was aboard the Oscar Dyson, there were multiple studies going on besides the Walleye Pollock survey. The same is true on the Hi’ialakai. The focus is on the mooring deployment and recovery but there are a professor and graduate student from North Carolina State University who are investigating aerosol fluxes.

Professor Nicholas Meskhidze earned his first Physics degree from Tbilisi State University (Georgia).  He completed his PhD at Georgia Institute of Technology (USA).  He is now an Associate Professor at NC State University Department of Marine Earth and Atmospheric Sciences.

Meskhidze’s study on this cruise is looking at sea spray aerosol abundance in marine boundary layer and quantifying their flux values. Sea spray is formed from breaking waves. Sea spray analysis begins by collecting the aerosol. Using electrical current, particles of a given size (for example 100 nanometer (nm)) are selected for. This size represents the typical size of environmental climatically important particles (70-124 nm). The next step is to remove all other particles typically found in the marine boundary layer, such as ammonium sulfate, black carbon, mineral dust and any organics. The remaining particles are sea salt.

Meskhidze is looking at the fluxes of the salt aerosols.  Sea salt aerosols are interesting.  If a salt aerosol is placed in 80% humidity, it doubles in size.  But then placed in 90% humidity, it quadruples in size. Due to their unique properties, sea salt aerosols can have considerable effect on atmospheric turbidity and cloud properties.

Aerosols are key components of our climate but little is known about them. Climate models are used to predict future climatic change, but how can one do this without understanding a key component (aerosols)?

Personal Log

The galley (ship’s kitchen) is a happening place three times a day.  The stewards are responsible for feeding 30-40 people.

Chief Steward Gary Allen is permanently assigned to the Hi’ialakai. He has worked for NOAA for 42 years and he has stories to tell. He grew up in Tallahassee, Florida and his early work was at his father’s BBQ stand. He attended Southern University on a football scholarship and majored in food nutrition. After an injury, he finished school at Florida A & M. He worked for a few years in the hotel food industry, working his way up to executive chef. Eventually he was offered the sous chef job at Brennan’s in New Orleans. He turned it down to go to sea.

Chief Steward Allen Gary

Chief Steward Allen Gary

In 1971, he sailed for the first time with NOAA. The chief steward was a very good mentor and Gary decided to make cooking at sea his career. He took a little hiatus but was back with NOAA in 1975, where he would spend 18 years aboard the Discoverer and would become chief steward in 1984. He would sail on several other ships before finding his way to the Hi’ialakai in 2004.

In the 42 years at sea, Gary has seen many changes. Early in his career, he would only be able to call home from ports perhaps every 30 days. Now communication allows us to stay in contact more. He is married to his wife of 43 years and they raised 3 daughters in Seattle.

I asked him what he enjoys the most about being at sea. He has loved seeing new places that others don’t get to see. He has been everywhere, the arctic to Antarctica. He enjoys the serenity of being at sea. He loves cooking for all the great people he meets.

I met Ava Speights aboard the Oscar Dyson in 2013 when she was the chief steward and I was participating in the walleye pollock survey as a Teacher at Sea. She has been with NOAA for 10 years.

Ava Speights (on the right) and me

Ava Speights (on the right) and me

She and a friend decided to become seamen. Ava began working in a shipyard painting ships. In 2007, she became a GVA (general vessel assistant) and was asked to sail to the Bahamas for 2 weeks as the cook. This shifted her career pathway and through NOAA cooking classes and on the job training, she has worked her way up to chief steward.

She is not assigned to a specific ship. She augments, meaning she travels between ships as needed. She works 6 months of the year, which allows her to spend time with her 2 daughters, 1 son, 2 stepdaughters and 4 grandchildren. Her husband is an engineer with NOAA. Her niece is an AB (able bodied seaman) on deck. Her son is a chief cook for Seafarer’s.  And her daughter who just graduated high school will be attending Seafarer’s International Union to become a baker.  Sailing must run in her family.

She loves to cook and understands that food comforts people. She likes providing that comfort.  She has also enjoyed traveling the world from Africa to Belgium.

2nd Cook Nick Anderson

2nd Cook Nick Anderson

Nick is 2nd cook and this is his first cruise with NOAA. He attended cooking school in California and cooked for the Coast Guard for 6 years where he had on the job training. In 2014, he studied at the Culinary Institute of America and from there arrived on the Hi’ialakai. He also is an augmenter, so he travels from ship to ship as Ava does.

 

 

 

Did You Know?

The Hi’ialakai positioned mooring 13 in an area with a 6 mile radius known as the Aloha Station. Check out all of the research that takes place here at Station Aloha. There is a cabled observatory 4800 meters below the ocean surface. A hydrophone picks up on sounds and produces a seismograph. Check the results for the night the anchor was dropped.

Howard Gray School in Scottsdale, Arizona.

Personal Log:

Hi my name is Sue Cullumber and I am a science teacher at the Howard Gray School in Scottsdale, Arizona. Our school provides 1:1 instruction to students with special needs in grades 5-12 and I have been teaching there for over 22 years!  In less than two weeks I will be heading out to the Atlantic coast as a NOAA Teacher at Sea.  I am so excited to have this opportunity to work with the scientists aboard the NOAA ship Gordon Gunter.

I applied to the NOAA Teacher at Sea program for the following reasons:

First, I feel that directly experiencing “Science” is the best way for students to learn and make them excited about learning. To be able to work directly with NOAA scientists and bring this experience back to my classroom gives my students such an amazing opportunity to actually see how science is used in the “real world”.

Secondly, I love to learn myself, experience new things and bring these experiences back to my students. Over the past several years I have had the opportunity to participate in several teacher fellowships.  I went to the Galapagos Islands with the Toyota International Teacher Program and worked with teachers from the Galapagos and U.S. on global environmental education. From this experience we built an outdoor habitat at Howard Gray that now houses four tortoises.  Students have learned about their own fragile desert environment, animal behavior and scientific observations through access to our habitat and had the opportunity to share this with a school in the Galapagos. I worked with Earthwatch scientists on climate change in Nova Scotia and my students Skyped directly with the scientists to learn about the field research as it was happening. Last summer I went to Japan for the Japan-US Teacher Exchange Program for Education for Sustainable Development. My students participated in a peace project by folding 1000 origami cranes that we sent to Hiroshima High School to be placed in the Hiroshima Peace Park by their students. We also  held a Peace and Friendship Festival for the community at Howard Gray.

This year we had a group of Japanese teachers visit our school from this program and students taught them about many of the sustainable activities that we are working on at school.  Each has brought new ideas and amazing activities for my students to experience in the classroom and about the world.

Lastly, Arizona is a very special place with a wide variety of geographical environments from the Sonoran Desert (home of the Saguaro) to a Ponderosa Pine Forest in Flagstaff and of course the Grand Canyon!  However, we do not have an ocean and many of my students have never been to an ocean, so I can’t wait to share this amazing, vast and extremely important part of our planet with them.

So now I have the chance of a lifetime to sail aboard the NOAA ship Gordon Gunter on an Ecosystem Monitoring Survey. We will be heading out from Newport, RI on June 5th and head up the east coast to the Gulf of Maine and then head back down to Norfolk, Virginia. Scientists have been visiting this same region since 1977 from as far south as Cape Hatteras, NC to the an area up north in the Bay of Fundy (Gulf of Maine between the Canadian provinces of New Brunswick and Nova Scotia).  They complete six surveys a year  to see if the distributions and abundance of organisms have changed over time. I feel very honored to be part of this research in 2013!

One of the activities I will be part of is launching a drifter buoy. So students are busy decorating stickers that I will be able to put on the buoy when I head out to sea.  We will be able to track ocean currents, temperature and GPS location at Howard Gray over the next year from this buoy.  Students will be studying the water currents and weather patterns and I plan to hold a contest at school to see who can determine where the buoy will be the following month from this information. While out at sea my students will be tracking the location of the Gordon Gunter through theNOAA Ship Tracker and placing my current location on a map that one of my students completed for my trip.

Spending time with my husband, Mike, and son, Kyle.

Outside of school, I love to spend most of my free time outdoors – usually hiking or exploring our beautiful state and always with my camera!  Photography is what I often call “my full-time hobby”.  Most of my photos are of our desert environment, so I look forward to all amazing things I will see in the ocean and be able to share with my husband and son, students and friends!  One of my passions is to use my photography to provide an understanding about the natural world, so I am really looking forward to sharing this fantastic adventure with everyone through my blog and photos!

WACS Field Campaign Update

Greetings from Georges Bank off the coast of New England! This is our first of 2 sampling stations during the Western Atlantic Climate Survey (WACS) field campaign, over the next 9 days. Our current location was chosen due to its high chlorophyll values, indicating productive waters. Shortly after our arrival here approximately 0700 on the 20th, the Sea Sweep instrument was deployed, and aerosol collection began (see picture below). However, for many of the scientists onboard, data collection began almost immediately after disembarking Boston, on the 19th.

The Sea Sweep

Photographs showing the Sea Sweep (top left), deployment of the Sea Sweep (bottom left), and Sea Sweep underway with bubble generation and aerosol collection taking place (right).

Upon my arrival to the ship in Boston, I quickly learned that this field campaign is a little unusual due to the sheer volume of equipment being utilized, and the short nature of the cruise itself. As we disembarked the Coast Guard pier in Boston, a running joke being echoed around the ship was, “30 days of science in 9 days…. ready, set, and GO!”

Science vans on deck

Looking from the bow towards the bridge, not visible in this photograph due to the mobile lab vans that have been installed on the deck for this cruise.

Over 9 mobile research vans were loaded onto the Ron Brown in preparation for this campaign making for a “low-riding ship”, joked our captain at our welcome meeting on the 19th. Each van contains multiple instruments, computers, ancillary equipment and supplies, and they also serve as research labs for the science teams to work in.

During the past two days, I have been making the rounds to each of these lab vans to hear more about the science taking place in each. With the help of the Chief Bosun, Bruce Cowden, I have also been able to shoot some video of these visits. With the assistance of Bruce, I am learning how to stitch these clips together into some fun short video pieces, so stay tuned for more to come!

A Little about the Sea Sweep

The Sea Sweep instrument consists of floating pontoons that hold a metal hood. The hood is mounted on a frame that protrudes below the water line when deployed, with two “frizzles” or “bubble maker” nozzles that air is pumped through to produce freshly emitted sea spray particles. These particles are then collected through two intake pipes attached to the hood, and are piped into the AeroPhys van. From there, samples are collected and also the intake is drawn into other vans for additional measurements.

Comparison of Sea Sweep Data with “the Bubbler”

Aerosol generator

Scientist Bill Keene from University of Virginia talking to me about “the bubbler”.

Sea spray particles are also being produced and collected via another method onboard, allowing for comparison with the Sea Sweep data. The picture below shows bubbles being generated in seawater that is fed into a large glass tower. This is an aerosol generator (a.k.a. “the bubbler”) brought on board by the University of Virginia. Through sampling with both the Sea Sweep and the bubbler, a greater size range and variety of aerosols can be sampled throughout the cruise.

Personal Log

After waiting a day or so for things to settle down and instruments to get up and running, I was eager to dive right in and be put to work on board. After an announcement made by the chief scientist, Trish Quinn, during our first evening meeting I was quickly solicited by a few different people to help with a range of tasks. So far these have included helping change impactor filters necessary for aerosol sampling 3 times a day (1 of these switches has been happening at 0500, making for some early mornings but pretty sunrises), getting raw sea water samples every 2 hours from different sampling points on board, preparing sea water samples for different analysis such as surface tension, and measuring samples for chlorophyll, dissolved organic carbon and particulate organic carbon.

Amongst all the sampling taking place however, it has been nice to take a break every once in a while to enjoy the extremely calm and settled weather we are having. A very memorable moment yesterday occurred when an announcement over the ship’s intercom alerted all aboard to a pod of whales off the port bow. It was nice to see the excitement spread, with both crew and science team members racing to the bow in unison with cameras in tow!

Introduction: Purpose of the Cruise

Gina Henderson, NOAA Teacher at Sea 2012

Hello from Annapolis, MD! My name is Gina Henderson and I am very excited about my imminent departure to Boston this coming Saturday as part of the NOAA Teacher at Sea program. In Boston  I will rendezvous with the Ronald H. Brown NOAA ship and join the science team to conduct experiments aimed at collecting in situ measurements of ocean-derived aerosols. The purpose of this experiment is to characterize the cloud-nucleating abilities of these aerosols. We also aim to sample atmospheric particles, gases, and surface sea water to assess the impact of ocean emissions on atmospheric composition.

A Little about Me

I am an Assistant Professor in the Oceanography Department at the United States Naval Academy. Here, I teach courses in climate science, physical geography and weather. My research to date has focused on land-atmosphere interactions using computer climate models, understanding the role of snow cover in the hydrologic and global climate system, and the influence of such elements on atmospheric circulation and climate change.

Growing up on the east coast of Ireland, my interest in climatology was awakened from an early age having been exposed to the elements through outdoor pursuits including sailing, travel, and hiking. I have found that sharing my enthusiasm and passion for these sciences, focusing on the application of how they relate to our day-to-day lives and the environment in which we live, is an excellent platform to foster student interest and participation.

Having worked as a sail racing coach in Ireland, and captaining boats in the Caribbean during my undergraduate summers, I was eager to get back to the sport after relocating to Annapolis. Since my arrival at the Academy, I have also been volunteering as a coach for the Varsity Offshore Sailing Team which has been a great experience so far and helped me learn more about my students outside of the classroom.

Going into my second year teaching at the Naval Academy, I am excited to get this opportunity to participate in this NOAA field work campaign. Having spent the last few weeks as the science officer for a Yard Patrol cruise, where we took a group of 17 midshipmen and introduced them to various oceanographic and meteorologic instrumentation on board the Oceanography Department’s dedicated Yard Patrol training vessel, I hope to acquire new fieldwork skills and experiences while aboard the Ron Brown and to use such experiences back in Annapolis.

The timing of this research cruise coincides with the start of the semester back at the Naval Academy. This semester, I am teaching two sections of the upper level major elective course, Global Climate Change. While it will be challenging to be absent from the classroom for the first two weeks of class, I plan on engaging with my students virtually and as close to real-time as communications allow  through this blog.

With this in mind, after a colleague introduces the course policy statement and syllabus next Monday 20 August, I am asking all students to take 10-20 minutes to google the underlined terms in the “Introduction: purpose of this cruise” section above, beginning with the NOAA Teacher at Sea Program. Students should write a brief summary (2-3 sentences) of what they find, focusing on the program goal(s). Students should then research the other underlined terms and write a brief summary (1-2 sentences) of what they should know about these terms from their previous course, SO244: Basic Atmospheric Processes. This assignment will be submitted via email to Prof. Henderson before the beginning of class on Tuesday August 21.

Science and Technology Log

As I said yesterday, the oceanographic work on the boat basically falls into three categories: physical, chemical and biological. Today I will talk a bit more about the chemistry component of the work on the R/V Walton Smith. The information that the scientists are gathering from the ocean water is related to everything that we learn in science at Key – water, weather, ecosystems, habitats, the age of the water on Earth, erosion, pollution, etc.

First of all, we are using a CTD (a special oceanographic instrument) to measure salinity, temperature, light, chlorophyll, and depth of the water. The instrument on this boat is very large (it weights about 1,000 lbs!) so we use a hydraulic system to raise it, place it in the water, and lower it down into the water.

CTD

Lindsey takes a CO2 sample from the CTD

The CTD is surrounded by special niskin bottles that we can close at different depths in the water in order to get a pure sample of water from different specific depths. Nelson usually closes several bottles at the bottom of the ocean and at the surface and sometimes he closes others in the middle of the ocean if he is interested in getting specific information. For each layer, he closes at least 2 bottles in case one of them does not work properly. The Capitan lowers the CTD from a control booth on 01deck (the top deck of the boat), and two people wearing a hard hat and a life vest have to help guide the CTD into and out of the water. Safety first!

Once the CTD is back on the boat, the chemistry team (on the day shift, Lindsey and I are the chemistry team!) fills plastic bottles with water from each depth and takes them to the wet lab for processing. Throughout the entire process, it is very important to keep good records of the longitude and latitude, station #, depth of each sample, time, etc, and most importantly, which sample corresponds to which depth and station.

We are taking samples for 6 different types of analyses on this cruise: nutrient analysis, chlorophyll analysis, carbon analysis, microbiology analysis, water mass tracers analysis and CDOM analysis.

The nutrient analysis is to understand how much of each nutrient is in the water. This tells us about the availability of nutrients for phytoplankton. Phytoplankton need water, CO2, light and nutrients in order to live. The more nutrients there are in the water, the more phytoplankton can live in the water. This is important, because as I wrote yesterday – phytoplankton are the base of the food chain – they turn the sun’s energy into food.

Carbon

Sampling dissolved inorganic carbon

That said, too many nutrients can cause a sudden rise in phytoplankton. If this occurs, two things can happen: one is called a harmful algal bloom.  Too much phytoplankton (algae) can release toxins into the water, harming fish and shellfish, and sometimes humans who are swimming when this occurs.  Another consequence is that this large amount of plankton die and fall to the seafloor where bacteria decompose the dead phytoplankton.  Bacteria need oxygen to survive so they use up all of the available oxygen in the water. Lack of oxygen causes the fish and other animals to either die or move to a different area. The zone then becomes a “dead zone” that cannot support life. There is a very large dead zone at the mouth of the Mississippi River. So we want to find a good balance of nutrients – not too many and not too few.

The chlorophyll analysis serves a similar purpose. In the wet lab, we filter the phytoplankton onto a filter.

chlorophyll

I am running a chlorophyll analysis of one of the water samples

Each phytoplankton has chloroplasts that contain chlorophyll. Do you remember from 4th grade science that plants use chlorophyll in order to undergo photosynthesis to make their own food? If scientists know the amount of chlorophyll in the ocean, they can estimate the amount of phytoplankton in the ocean.

Carbon can be found in the form of carbon dioxide (CO2) or in the cells of organisms. Do you remember from 2nd and 4th grade science that plants use CO2 in order to grow? Phytoplankton also need CO2 in order to grow. The carbon dioxide analysis is useful because it tells us the amount of CO2 in the ocean so we can understand if there is enough CO2 to support phytoplankton, algae and other plant life. The carbon analysis can tell us about the carbon cycle – the circulation of CO2 between the ocean and the air and this has an impact on climate change.

The microbiology analysis looks for DNA (the building-blocks of all living organisms – kind of like a recipe or a blueprint). All living things are created with different patterns or codes of DNA. This analysis tells us whose DNA is present in the ocean water – which specific types of fish, bacteria, zooplankton, etc.

The water mass tracers analysis (on this boat we are testing N15 – an isotope of Nitrogen, and also Tritium – a radioactive isotope of Hydrogen) helps scientists understand where the water here came from. These analyses will help us verify if the Mississippi River water is running through the Florida Coast right now. From a global viewpoint, this type of test is important because it helps us understand about the circulation of ocean water around the world. If the ocean water drastically changes its current “conveyor belt” circulation patterns, there could be real impact on the global climate. (Remember from 2nd and 3rd grade that the water cycle and oceans control the climate of Earth.) For example, Europe could become a lot colder and parts of the United States could become much hotter.

This is an image of the conveyor belt movement of ocean currents

The last type of analysis we prepared for was the CDOM (colored dissolved organic matter) analysis. This is important because like the water mass tracers, it tells us where this water came from. For example, did the water come from the Caribbean Sea, or did it come from freshwater rivers?

I am coming to understand that the main mission of this NOAA bimonthly survey cruise on the R/V Walton Smith is to monitor the waters of the Florida Coast and Florida Bay for changes in water chemistry. The Florida Bay has been receiving less fresh water runoff from the Everglades because many new housing developments have been built and fresh water is being sent along pipes to peoples’ houses. Because of this, the salinity of the Bay is getting higher and sea grass, fish, and other organisms are dying or leaving because they cannot live in such salty water. The Bay is very important for the marine ecosystem here because it provides a safe place for small fish and sea turtles to have babies and grow-up before heading out to the open ocean.

Personal Log

This cruise has provided me great opportunities to see real science in action. It really reinforces everything I tell my students about being a scientist: teamwork, flexibility, patience, listening and critical thinking skills are all very important. It is also important to always keep your lab space clean and organized. It is important to keep accurate records of everything that you do on the correct data sheet. It can be easy to get excited about a fish or algae discovery and forget to keep a record of it, but that is not practicing good science.

It is important to keep organized records

It is also important to stay safe – every time we are outside on the deck with the safety lines down, we must wear a life vest and if we are working with something that is overhead, we must wear a helmet.

I have been interviewing the scientists and crew aboard the ship and I cannot wait to return to Arlington and begin to edit the video clips. I really want to help my students understand the variety of science/engineering and technology jobs and skills that are related to marine science, oceanography, and ships. I have also been capturing videos of the ship and scientists in action so students can take a virtual fieldtrip on the R/V Walton Smith. I have been taking so many photos and videos, that the scientists and crew almost run away from me when they see me pick up my cameras!

The food continues to be wonderful, the sunsets spectacular, and my fellow shipmates entertaining. Tomorrow I hope to see dolphins swimming alongside the ship at sunrise! I will keep you posted!!

Did you know?

The scientists and crew are working 12-hour shifts. I am lucky to have the “day shift” which is from 8am to 8pm. But some unlucky people are working the “night shift” from 8pm to 8am. They wake-up just as the sun is setting and go to sleep right when it rises again.

Science and Technology Log

Question of the day:  When I view your travels aboard the Oregon II on NOAA’s Ship Tracker website it looks as though you go as far as the continental shelf and then turn back towards the shore again.  Why don’t you go into the deep water?

Our groundfish survey course.

Answer:  If you were studying animals in the rainforest you would want to make sure to stay in that specific area.  You wouldn’t want to include Arctic animals in your report which are from a completely different biome.  The same goes for ocean life.  As depth, temperature, and amount of light change in the ocean so do the habitats and the animals that live in them.  On this groundfish survey we are focusing on offshore species that live in “shallow” waters up to 60 fathoms (361 feet).  If we were to go out into the deep water then our reports wouldn’t be as accurate.

Topic of the Day:  Science

What is science?  Can you come up with a good definition?  Difficult isn’t it.  There are many definitions that refer to science as the study of the natural world, systematic knowledge, etc. but something that’s often left out of the definition is that it can be used to make predictions.

We have all been conducting scientific experiments since we were old enough to formulate questions about our environment: “Will this ball bounce?”,  “Can I get it to bounce higher?”,  “Will ball #1 bounce higher than ball #2?”  The knowledge we have collected from these experiments allow us to make accurate predictions.  “I think ball #2 would be better for playing tennis than ball #1.”  Now keep in mind, the more we know about a subject, the better our predictions will be.

The more information we have the better our predictions become. Image: http://www.exploratorium.edu/baseball/bouncing_balls.html

Did you know that the ocean covers over 70% of the Earth’s surface but more than 95% of it remains unexplored.  This means we have a lot to learn if we want to accurately predict the relationships between the ocean, the atmosphere and the living things on our planet. To address these gaps in our knowledge, thousands of people working for the government, universities and private industries, are trying to collect the information we need to make the most accurate predictions possible.  Perhaps by expanding our knowledge we will be better equipped to formulate some solutions to the problems we have created in the seas such as  pollution (particularly plastics), climate change and overfishing.  These issues are drastically changing oceanic ecosystems which in turn affect the life on our planet.

One thing that sets science apart from other arenas is that is it based on verifiable evidence.  We are not talking about video footage of bigfoot or pictures of UFO’s here, we are talking about evidence that is easily confirmed by further examination or research.  I don’t think many people consider all of the expertise that goes into collecting this kind of scientific data–it’s not just scientists.

Not all evidence is verifiable.

Onboard the Oregon II there are engineers that make sure the ship and all its parts are functional, skilled fishermen that operate the cranes and trawling equipment, officers from the NOAA Corps that navigate and assist the captain in commanding the ship, cooks that feed a hungry crew and the scientists.  Conducting scientific research is a team effort that requires a variety of skilled personnel.

Too often people underestimate the amount of time and labor that actually goes into collecting the information we have about our planet and its inhabitants.  In fact, many people dismiss scientific evidence as unimportant and trivial when in actuality it is based on the most technologically advanced methods that are available.  Scientific data, and conclusions derived from the data, are peer-reviewed (looked at by others in the field) before it is published or presented to the general public.

This is why it is so important to take heed to the reports about the changes taking place in the ocean’s waters. Without the data from NASA’s satellites in the sky,  NOAA’s ships on the sea and other sources too numerous to mention, we wouldn’t know the extent of the damage that’s being done to the ocean.

NOAA’s Teacher at Sea program has clearly demonstrated how good science is done.  I experienced first hand the importance of random sampling, scientific classification of organisms, repeating trials to ensure the accuracy of results, team work, safety, publishing data for the public to review and always having backup equipment.  I’m looking forward to sharing these experiences with my students.  Thank you NOAA!

Personal log:

My time aboard the Oregon II is coming to an end.  We have finished up our last stations and cleaned up the workrooms.  Now its back to Pascagoula, Mississippi.  It has been a wonderful experience!  For those of you that are wondering what I did each day on the ship it was pretty routine.

9:00 AM : Go to the galley for some juice and coffee.  Hot breakfast ends at 8:00 AM but they always have cereal and fresh fruit to eat.  In the galley there are two tables that each seat six people.  At the end of each table is a small TV so we can watch the news, our anything else that happens to be on DirectTV.

This is a picture of my room. I have the bottom bunk and my roommate sleeps on the top. The curtains are very nice for privacy since we work different shifts.

There is a bathroom (head) that my roommate and I share with our two neighbors. Each room has its own entry door to the bathroom.

This is the galley where all of our meals are served. It's also stocked with lots of yummy snacks and drinks!

9:30 AM:  After some coffee, juice and conversation I head upstairs to the lounge so I can check my e-mail and work on my blog.  The lounge has some comfortable seats, a big TV, lots of 8mm movies, two computers for the fishermen, and an internet cord for laptops.  Usually David, the ornithologist (bird scientist), is here working when I arrive so we usually chat for a while.

This is the lounge.

11:00 AM:  Lunch time!  everyday the chefs make amazing food for us to eat.  They’ve served bbq ribs, prime rib, turkey, quail, crab cakes, shrimp, mahi-mahi, ham, crab legs, pork loin, steaks and lots of other amazing side dishes and desserts.  Both chefs are retired from the Navy where they were also cooks.

12:00 noon: Head to the dry lab to start my shift.  At the start of every shift Brittany, our team leader, writes down all of the stations we will be going to as well as how many miles it takes to get there.

This is the "dry lab" where we spend our time waiting for the next trawl or plankton station. In this room there are computers dedicated to navigation, depth imagery and fisheries data.

5:00 PM:  Supper time!  Back to the galley for some more excellent food!

12:00 midnight:  Night crew comes in to relieve us from our 12 hour shift.  I quietly enter my room so I don’t wake up my roommate and hit the shower.  Then it’s to the rack (my bunk bed) with some ear plugs to block out the sounds of the engine.  The slow rocking of the waves makes a person fall asleep quickly after a long day at work.
