Science and Technology Log

In my previous blog posting, I explained the importance of plankton as base of the ecological pyramid upon which much of marine life in this ecosystem depends.  The past few days, I have witnessed and experienced in-person how scientists aboard this sophisticated research vessel collect and analyze sea water samples for plankton. 

Yesterday I spent some time with Kyle Turner, a guest researcher from the University of Rhode Island doing his M.S. in Oceanography.  He operates a highly sophisticated device called the Imaging FlowCytobot (IFCB).  I was fascinated to learn how it works.  It is basically a microscope and camera hooked up to the ship’s water intake system.  As the waters pass through the system, laser beams capture images of tiny particles, mostly phytoplankton (tiny photosynthetic drifters).  As particles do, they scatter the light or even fluoresce (meaning, they emit their own light).  Based on this, the computer “zooms in” on the plankton automatically and activates the camera into taking photographs of each of them!  I was amazed at the precision and quality of the images, taken continuously as it pipes in the water from below.  Kyle says this helps them monitor quality and quantity of plankton on a continual basis.

The various kinds of phytoplankton are neatly displayed on the IFCB’s computer screen. See my previous blog for a photo of the dazzling and colorful array of plankton out there! Plankton may lack the popularity of the more charismatic sea animals like whales, but much of life in the ocean hinges on their welfare.


Career Corner

Hello, students (especially bio majors).  In this corner of my blogs, I will interview some key research personnel on the ship to highlight careers.  Please learn and be inspired from these folks.

Here is my interview with Kyle Turner.

Q. Tell us something about your graduate program.

A. My research focuses on phytoplankton using bio-optical methods. Basically, how changes in light can tell us about phytoplankton in the water.

Q. How does this IFCB device help you?

A. It gives me real time information on the different types of phytoplankton in the location where we are.  We can monitor changes in their composition, like the dominant species, etc.

Q. Why are phytoplankton so important?

A. They are like trees on land. They produce about half the oxygen in the atmosphere, so they’re super important to all life on earth. They are also the base of the marine food web.  The larger zooplankton eat them, and they in turn are eaten by fish, and so on all the way to the big whales.  They all rely on each other in this big ocean ecosystem.

Q. How are phytoplankton changing?

A. The oceans are warming, so we’re observing shifts in their composition.

Q. What brought you into marine science?

A. I grew up on the coast.  I’ve always liked the ocean. I love science.  So I combined my passions.

Q. What is your advice to my students exploring a career in marine science?

A. Looking for outside research opportunities is important.  There are so many opportunities from organizations like NASA, NSF, and NOAA.  I did two summer research internships as an undergrad.  First was with NASA when I was a junior.  I applied through their website.  That was a big stepping stone for me. A couple of years later, I did another summer project with a researcher who is now my advisor in graduate school.  That’s how I met her.

Q. What are your future plans?

A. I’d love to get into satellite oceanography to observe plankton and work for NASA or NOAA.


Personal Log

I am pleasantly surprised by how comfortable this ship is.  I was expecting something more Spartan.  I have my own spacious room with ample work and storage space, a comfortable bed, TV (which I don’t have time for!), and even a small fridge and my own sink. Being gently rocked to sleep by the ship is an added perk!

Some interesting animals seen so far

  • Flying fish (they get spooked by the ship, take off and fly several yards low across the water!)
  • Cow-nosed Rays (see photo and caption below)
  • Leather-backed Sea-turtle (I’m used to seeing them on the beach in Trinidad—see my previous blog.  It was a treat to see one swimming close by.  I was even able to see the pink translucent spot on the head).
  • Bottle-nosed Dolphins
  • Seabirds (lots of them…. four lifers already—more on this later!)
school of cow-nose rays
We saw large schools of Cow-nosed Rays closer to the coast. These animals feed on bivalve mollusks like clams and oysters with their robust jaws adapted for such hard food. They are classified as Near Threatened due to their reliance on oyster beds which are themselves threatened by pollution and over exploitation.

Welcome to a tour of the NOAA Ship Oscar Dyson.

Your tour guide today is the Room 11 Bear.

Allow me to explain.

When I am not a Teacher at Sea on the NOAA Ship Oscar Dyson, I am the special education preschool teacher in Room 11 at Nevada Avenue Elementary School in Canoga Park, California. My classroom has a classroom bear (made of construction paper) that “hides” every night when the students go home. In the beginning of the year, he is sort of easy to find, but as the year progresses, he is harder and harder to find. By the end of the year, only a paw or an ear might be showing!

The first thing my students want to do every morning is look for the bear.  When they find it, they excitedly explain where it is. Speech and language are things we work on in class all the time, and the bear gives us something fun to talk about! For some students, a single word might be the goal. Other students may be working on putting a few words together, or even enough to make a sentence.  It’s also a great time for them to learn prepositional words or phrases to describe where the bear is hiding, such as next to, under, beneath, or on top of.

Now it’s YOUR turn.  I hope you have fun touring the NOAA Ship Oscar Dyson with the Room 11 Bear and finding him in the photos where he decided to hide in a tricky spot.   He is in EVERY picture.

Science and Technology Log

Launch preparation
A launch getting ready to survey. The setup process takes some time and all of the preparation is necessary for accuracy in the data.
Heave, pitch, roll, and yaw describe the movements of a boat (or a plane). An inertial measurement unit reads those discrete movements. Source: wikipedia

In the last post I talked about hydrographic surveying, the software used and the multibeam echosounder on the survey boats (called launches). The software is setup in the cabin by the hydrographer in charge. It takes a good five minutes to get an accurate read from the GPS (global positioning system) receiver. Then it takes time for the IMU (inertial measurement unit) to respond and start to read the boat’s heave, pitch, roll, yaw, and heading values. 

hydrograpers
The hydrographer in charge (standing) is showing the hydrographer in training (seated) how to setup the day’s survey project using the echosounder software.
launch data storage
The four Fairweather launches have the same, high-end technology in their cabins used to collect data from the multibeam echosounder, CTD sensor, a sound speed system, and a positioning and altitude system.

Often, the launch drives in a circle eight in order for the positioning receivers to be “seen” by the satellites, as a  stationary object is more difficult to detect than one that is moving. Setting up the day’s project using the multibeam echosounder software also takes some time but all the steps need to be done properly and to the correct specifications prior to starting the sounder. If not, the locational data will be wildly off and the depths inaccurate.

Another task that must be done from the launch before starting to transect is to test the salinity and water temperature using a CTD probe, which is called a cast. I mentioned this in a previous post. CTD stands for conductivity, temperature and depth. In the general area where the launch will survey, the CTD drops slowly to the bottom of the seafloor, collecting data that will be fed into the hydrographic program. Salinity and temperature at different depths will slightly change the rate at which sound travels in water. Again, the CTD process makes the location and depths as accurate as possible and must be done.

Meg casts CTD probe
Casting the CTD probe into the survey location to get conductivity, temperature and depth readings.

Usually, the chief hydrographer sets the defined area to be transected for the day and this is usually a polygon. The launch will sweep with the multibeam echosounder the outside lines and then scan at parallel set distances between the lines, either in a roughly north-south direction or a roughly east-west direction. For this particular hydrographic project, coverage of survey lines can be spaced at about 400 meters apart or greater apart depending on the depth. Recall that the nautical chart of Bristol Bay from the last post showed soundings dotting the area. Solid bathymetric coverage is not always needed on these projects. The Cape Newenham area has proven to have gradually varying depths and is mostly quite flat so free from obvious obstructions like large boulders and sunken ships. 

Once the technology setup is complete in the cabin, the hydrographer shares the map window with the coxswain (the person in charge of steering or navigating the boat). The hydrographer sets the points and the lines so that the coxswain knows where to direct the launch. And by direct, I mean the coxswain uses compass direction and boat speed to get from place to place for the survey. And the hydrographer in charge turns the echosounder on and off when the launch is in position or out of position.

Coxswain
The coxswain navigates the survey line set by the hydrographer in charge.

Because the transects run parallel to each other and are equally spaced apart, the hydrographers call this technique “mowing the lawn,” (see video below) for they are essentially mowing the surface of the ocean while the multibeam echosounder is collecting soundings of the surface of the seafloor.

A video of someone mowing a lawn on a riding lawnmower

A day out on a launch will go from about 8:30am to about 4:30pm but sometimes an hour or so later. If the Alaskan weather is cooperating, the hydrographers want to do as much as they can while out on the launch. Once surveying is complete for the day, the hydrographer in charge has to close up and save the project. Then data get transferred to the larger workstations and shared drive on the Fairweather.

Meg on launch
Every day on the launch, at least on this leg, has been great with perfect weather. And today, the added bonus for me was the phenomenal geology as we surveyed right along the shore.


Personal Log

I’ve taken loads of photos and video while at sea. I have tried to post just those pictures that help explain what I’ve been trying to say in the text. I haven’t posted any video on here as the internet on the ship is very weak. These next photos are a tour of different parts of the NOAA Ship Fairweather.

  • view of the bridge 1
  • view of the bridge 2
  • view of the bridge 3

The above slide show gives an idea of what the bridge is like. The ship is steered from the bridge. All the navigational instruments and weather devices, among other tools, are found on the bridge.

emergency billet
These emergency billets are for me, TAS Stewart, Meg, and it’s posted on my door. For each emergency situation, Fire, Abandon Ship, or Man Overboard, there is a bell sound and the location on the ship where I am to muster. Life at sea is all about being ready for anything.

Laundry
Laundry machines available and detergent is supplied. No need to bring all your clothes. Also, sheets and towels are supplied.
Stairs
Stairs are called ladders on a ship. Makes sense to me – they’re often pretty steep. You must always hold a rail.
The Lounge

Yes, so this is the lounge and there can be meetings in here, training, movies, games, puzzles, quiet space, etc.
DVD in stateroom
Or, you can pop a DVD into a player in the Lounge, go back to your stateroom and watch. Or fall asleep. This is the original Blade Runner (which I never saw) and which I didn’t care for.
Finer things
The good folks of Ship Fairweather like to have a nice time every now and again, so they set up evenings, about once a leg, to have Finer Things. People come by, bring fine cheeses, fine chocolates, fine almonds, fine fig jelly, and fine maple sugar candy from Rhinebeck, NY, and have a fine time. And a disco ball.


Did You Know?

Inertial Measurement Units (IMU) technology that is so important for accurate hydrographic survey mapping was developed by the U.S. military. IMUs were used in the development of guided missiles, unmanned aerial vehicles (and now drones), battlefield reconnaissance, and target practice.

Science and Technology Log

NOAA celebrated the 50th anniversary of the 1968 launch of Ship Rainier and Ship Fairweather this past spring.  These two vessels together have provided 100 years of hydrographc service.  Its amazing to consider this vessel has been cutting through the waves for 50 years!

It took a few days for me to get familiar with the layout of Ship Rainier.  Let me take you on a video tour of several sections of the ship and welcome you aboard.

First some orientation.  The decks are identified with letters – where A represents the lowest level and G is the highest level.  “A deck” is actually a collection of tanks and bilge areas…the work of the engineering team mostly takes place on B deck in the engine room.  The ship also uses numbers to address areas of the ship – starting with 01 at the bow and 12 at the stern.  This way, any location on the ship can be identified by an address.

So lets get started on a tour…

Often, work days start with a meeting on the Fantail of this ship. This is on the D deck – the deck with most of the common spaces on board.

Fantail

This is a diagram of the fantail.

Fantail Safety Briefing

A typical morning safety briefing before a busy day of launches.

We’ll start our walk at the base of the stairs on the starboard side of the front of the fantail.  You’ll see the green coated bollards on several decks.  These are used for tying off the ship when in port.  The large yellow tank is gasoline for the outboard motors.  It is setup to be able to jettison over the side in a fire emergency.

Next, we’ll walk in the weather tight door amidships (center) of the front of the fantail. As we walk forward, notice the scullery (dishwashing area) on the left side followed by the galley (kitchen). To the right is the crew mess (eating area). Continuing ahead, we’ll walk through the DC ready room (Damage Control) and into the wardroom (officers eating area) and lounge.

Next, we’ll start in the Ward room and proceed up the stairs to the E deck. Here we’ll walk by several officers quarters on either side of the hall. Then we’ll turn and see a hallway that goes across the E deck and is home to FOO’s (Field Operations) and XO’s (Executive Officer’s) offices.   Then we’ll step out onto the deck and walk towards the deck on the bow (the front of the ship).

Starting once again at the fantail, now we’ll proceed up the steps to the E deck.  This is the level where the davits are mounted (small cranes) that support the launches (small boats).  After passing the base of the davits, we stop into the boat shop.  This is where engineering maintains the engines of all of the launches on board Rainier.   Next we walk up to the F level and turn towards the stern to see the launches from alongside.  Notice, also, the large black crane in the center of the deck that is used for moving additional equipment and launches.  Finally, we’ll walk all the way up the port side to the fly bridge on the G level.  Here you’ll see “Big Eyes”, my favorite tool on the ship for spotting things in the distance.  As I turn around you’ll see the masts and antennas atop this ship for communications and navigation.  The grey post with the glass circle on it is the magnetic compass –  which can actually also be viewed from the bridge below with a tube that looks up from the helm position.  You might also notice this where the kayaks are stored – great for an afternoon excursion while at anchor!

Here is a quick look in the plot room that is also located on the F deck just aft of the bridge.  This is one of two places where the hydrograph scientists work to collect and process the data collected with the MBES systems.

In the front of the ship on the F deck is the bridge.  This is the control center for the ship and the location of the helm.  There is more detail on the bridge in an earlier post.  The sound you hear is a printer running a copy of the latest weather updates.

Finally, visit my C-03 stateroom.  My room has two bunks and plenty of storage for two people’s gear.  There are four staterooms in this cluster that share two heads (bathrooms).  The orange boxes on the wall are EEBDs (Emergency Escape Breathing Devices).  These are located throughout the ship and provide a few minutes of air to allow escape in the event of fire.  Notice at the top of the steps were back to the hallway and steps just outside of the lounge on D level.

The entire engineering department is not included in these videos and exists mostly on the B level.  Please see my second blog post for more detail on engineering systems and several photos!

Personal Log

Sunday, July 8, 1000 hrs.
We’re coming around the northwestern most point of Washington State this morning and then turning south for the Oregon Coast.  The ship is rolling a bit in the ocean swells.  I’ve come to be very used to this motion.  Last night we had a chance to go ashore in Friday Harbor, in the San Juan Islands for a few hours.  I was surprised just how ‘wobbly’ my legs felt being back on solid ground for a while.  My ship mates tell me this is how it is the first few times back ashore after being at sea!

This has been a great experience – one of plenty of learning and a real appreciation for the work accomplished by this team.  I look forward to drawing in all I can in the last day on the ocean.

Who is On Board?

Mike Alfidi

This is our cox’n Mike Alfidi at the helm of Launch RA-3.

This is augmenter Mike Alfidi.  Mike has been a cox’n (boat driver) here on Rainier for about two years now, and has quite a bit of past experience in the Navy.  Mike is a part of the deck department.  His primary duties here are driving small boats and handling equipment on the decks.  As an “augmenter,” he makes himself available to NOAA to be placed as directed on ships needing his skills.

One of the things Mike loves about his work is getting to see beautiful places like Southeast Alaska.  And, he appreciates updating charts in high traffic areas like the harbor at Pelican.  He loves to be a part of history – transitioning survey data from the old lead line to the much more accurate MBES.  One of the toughest parts, he says, is riding our rough seas and plotting in less trafficked areas.  He did a great job of piloting our launch just as the hydro scientists needed to collect the data we were after!

Stairwell

A ladder well on Henry B. Bigelow

The ladder wells.  On the Henry B. Bigelow these sets of steps will take you everywhere that you need to go throughout the day.  Life on a ship is interesting in the fact you don’t ever leave while on your mission.  This is where you sleep, where you eat, where you work and where you hang out with your friends.

One of the most frequently received questions from my students back home is about life on the ship.  Since the past couple of days have been relatively slow in terms of fishing (due to inclement weather), I have decided to highlight the areas of the ship where I spend the most of my time.

My room (likely about the size of your own room at home) happens to be a quad which means I share my room with 3 other people.  In addition to two bunk beds, we have a work area (w/a small TV) and a compact bathroom.  While it is definitely a bit cramped, the 4 of us are split between the 2 shifts (My shift is 12am-12pm.).   The end result is that there are no more than 2 people in the room at any time, so it ends up working out quite well.  Notice the handle in the shower.  This comes in handy when you are trying to clean up and not wipe out as sometimes the ship can move around quite a bit!  You may also notice the emergency billet  on the door.  This tells each member of the crew where to go and also what to do during emergency situations.

 

The food on the ship has been amazing.  As students in my classroom will attest, I swore I was going to go on a diet during this cruise .  While that would be possible, given there are always tons of healthy options, it’s not everyday when there is a BBQ spare rib option for lunch!  Additionally, when you are working off and on over the course of your 12 hour shift, eating food is sometimes a good way to pass the time.  While I don’t think I have gained weight, I definitely do not think I will lose weight over the final 12 days of the cruise.

 

The labs where the scientists work are obviously where we spend a large part of our day (or my case, night).  The picture to the left is where many of the fish are cataloged and processed.  The photo in the top right are where some of the specimens are preserved for later examination in not only NOAA facilities, but also other other research facilities around the world.  The area in the bottom is a planning/observation space where the science team goes to gather, plan and share information related to their research mission.

 

Finally, there is the lounge and fitness area.  The lounge is really nice with large recliners which are a wonderful way to relax after a long shift.  There is Direct TV which is nice for both sports and news and the ship also has an impressive collection of movies for the crew to enjoy.  The fitness area in the bottom right is my favorite space on the ship.  While neither expansive nor pretty, it is a great place to go to burn off steam.  There is a TV and enough equipment to break a sweat.  Although I must admit, its extremely challenging to use an elliptical during a storm with rough seas.  Especially with low ceilings! 🙂

How did you do on the quiz? I thought I would share a few more interesting aspects about life on a ship.

All doors and drawers are latched. You just can't have door and drawers swing back and forth as the ship rocks on the waves.

We must do our own laundry. There are four types of water. Of course fresh water and salt water you've heard of before. On the ship we also have brown water, which is water from laundry and sinks. We also have black water, which is the water from the head. You do remember what the head is don't you?

Science and Technology Log:
I have read a lot about travel during the “age of sail,” and the Gloucester, Massachusetts fishing boom years. Believe you me, it wasn’t all swashbuckling pirates, romantic whale captures and sea shanties. Now though? Life at sea, on the surface, has all of the amenities and trappings of life at home: shower, a place to sleep, delicious food, work and friends. Easy, especially if you are, I should add, a Teacher at Sea. Beneath the surface though… it gets complicated. How is it possible to turn on a faucet and get fresh water when you are surrounded by brine? Where is the food stored before it arrives on your plate? Where does the electricity come from when you flip a switch? (I assure you, our boat is not Pollock powered, nor do we drag an extra long extension cord…)

Before I go into the picture journey of the ship and her inner workings, let me tell you about routine matters. In fact, I want to share with you my daily routine on the Oscar Dyson, and then, afterward, take you into the Belly of the Beast. Go ahead. Click on Issue 11.

I want to especially thank the Chief Marine Engineer, Jeff Hokkanen, for a stellar hour and a half tour of the inner workings of the ship. He probably didn’t realize that his job was red carpet material, but after about 100 photo opportunities from Staci, Megan Stachura (a graduate student from the University of Washington) and me, I think we have convinced him…

I was most curious about how the Oscar Dyson dealt with issues that I don’t think much about at home: power, water and waste. How is it possible to produce enough electricity for me to turn on lights, be charging my computer and driving along at 11 knots? Where does the water come from, when we are surrounded by the sea? Where does it all go, when, you know, we ‘go?’

There was no touching, we swear.  Staci and Megan.

Power: We have four diesel engines on board. They are enormous Caterpillars that were built into the ship. The engines power generators that then run electric motors… all controlled by a computerized generator control panel. On average, we use 2,500-3,000 gallons of marine diesel fuel every day we are out to sea. Additionally, every 1,000 miles the 150 gallons of oil in the engines needs to be changed. I know you are adding up the prices in your head. It is pretty amazing how much good science costs, isn’t it? Here is how I see it: manage the single largest Alaskan fishery (some argue in the world) to ensure that it is healthy and here for generations in the future, or let Walleye Pollock go the way of the Atlantic Cod on the Grand Banks? Once I do the math, it all seems worth it.

Thumbs up for vacuum distillation water systems!

Thumbs up for vacuum distillation water systems!

Each human being on this boat uses about 50 gallons of water a day. The water is produced by drawing on seawater, running it through a vacuum and boiling it. Water in the vacuum boils at a lower temperature, saving energy. After distillation, the water is treated with a UV light (similar to how a backpacking steri pen works) and bromine. Seawater used to be in many ships’ toilets; if it contained phosphorescent bacteria, when you flushed, your effluent would fluoresce. (Oddly poetic for what I just described, no?)

Grey and black water treatment (not stinky).

Finally, what happens to ‘it’ all? The ship has two kinds of waste, grey water (from drains) and black water (sewage). According to international regulations, you cannot dispose of waste within three miles of shore. Most ships, once they have crossed that boundary? Heave ho. The Oscar Dyson treats it’s grey and black water in a septic system, chlorinates it, and then disposes of it, once we have crossed that 3 mile zone. When tested, it would classify as being safe to drink… …any takers? Food scraps are ground up and thrown overboard (outside the 3 miles), paper trash is incinerated, and aluminum recycled.

All in all, I think it is pretty fascinating how this ship supplies thirty people with their basic needs for weeks on end. I’ll leave you with a few bonus photos from our tour, and some fish cameos from our trawls. A heads up if you are about to scroll through my photos: I will describe the trawl operation in more detail in the future, but the general purpose of our trawls is to take the ages, weights, lengths, sexes and stomachs of individual fish we catch. Three of these operations (sexing, aging and taking the stomachs) are fatal to the fish…a hard reality to swallow when I have made the Walleye Pollock a beloved mascot. I choose to deal with this reality by taking inane photos with the fish. To sum up: photos of fish ahead. I make lots of faces.
