Science and Technology Log

The AHI research vessel was launched just prior to eight a.m. this morning with Scientist Joyce Miller and Jeremy Jones aboard. The red and silver sonar boat would continue mapping shallow areas near 23 degrees North and 166 degrees West in the Northern Hawaiian Island chain. The ship resumed running benthic habitat mapping lines also, filling in gaps from previous surveys. Half past noon brought the deployment of several divers to the hull of the ship to determine the installation of the Trackpoint II testing. They dove in adorned with black suits, colorful air tanks, and metal weight belts. It turned out that the Trackpoint II wasn’t installed properly and was off by 15 degrees. That noted, changes were made to computer software to account for the degree change. Another boat trip was organized for the La Perouse Pinnacle area. Coxswain Merlyn Gordon led me, ENS Amy Cox, Scientists Rob O’Connor and Jonathan Weiss out to sea to snorkel the reef ecosystem. Upon approaching La Perouse, it was determined to be too dangerous, so we changed course and swam the reef area near East Island. We returned to the ship a few hours later and the AHI followed suit, and was hoisted out of the water once again. The HI’IALAKAI transited to deeper waters and ship based TOAD operations and Trackpoint II testing carried on once again. Ten p.m. brought about the reoccurrence of shipboard mapping around the outer circumference of French Frigate Shoals using the onboard multibeam sonar system.

Personal Log

I awoke and after the morning ritual of breakfast and shower, I answered emails from students in my fourth grade classroom in Ashburn, VA. I climbed the stairs and passageway to the drylab to check to see if I could be of some assistance editing data. The efficient scientists were caught up on the editing so my services were not needed. I soon found out about an impromptu snorkeling trip and clambered to get ready and join the expedition. The seas were the calmest I had seen yet, so the ride was very smooth across the Pacific towards Perouse Pinnacle (a volcanic rock out cropping that serves as a good landmark in this area). The ocean looked like glass and the sun rays flashed and hit the water like bright diamonds. There was an underlying surge though, which might indicate a coming storm in the next 48 hours (according to sailors onboard).

After nearing Perouse, we could see the waves crashing around the rock, and pressed on for a safer snorkeling environment where we wouldn’t be churned to bits! We approached East Island and could see dark figures grazing the beach. Upon closer inspection, we realized they were not monk seals, but giant green sea turtles basking in the sun. Mating season was upon us, and many of the sea turtles were populating this area to find mates. We snorkeled in four different areas of the reef, being careful not to get near the beach or disturb the coral reef ecosystem. Several sea turtles were curious and encircled our boat, whereas I snapped some good photos.

I finally saw my first Ulua fish, indigenous to this area. The fish had eluded me prior to today and I had been told stories of their aggressive biting behavior. Although quite large, about 3-4 feet, I was told it was small compared to most. It swam around us, but never ATTACKED! It wasn’t nearly as ferocious as the picture the crew on board had painted in my mind. It was a very flat, circular fish with a silver sheen. We saw many school of fish, one of which was bright yellow, and neon green coral. I learned from Coxswain Gordon that some of the clouds above the reef bore a greenish undercast or tint. The color was reflected from the coral below and was an aide in locating reef areas. We returned to the HI’IALAKAI later in the afternoon and I spent the evening conducting some more interviews (which will be included in future logs). The sun and exercise tired me out and I fell asleep as soon as I hit the pillow in my stateroom.

QUESTION OF THE DAY for my fourth grade students: A habitat is the place where an organism lives and grows. Examples include ponds, forests, and a coral reef. A niche is the role an organism plays in its surroundings. A niche includes an animal’s complete way of life–where it lives, how and what it eats, and how it produces. Find out more about the giant green sea turtle. Think about why the turtle is laying on the beach also. List the answer’s to the sea turtle’s niche: 1) Where does it live? 2) How does it eat (what body parts does it have to aid in eating?) 3) What does it eat? (don’t say it eats Ms. Fye:)!! Ugh! 4) How does it reproduce? (Does it give birth to live young, lay eggs, etc?) 5) What resource did you use to find these answers?

ANSWER TO YESTERDAY’s Question: The ocean floor is full of nutrients and food particles resulting from decaying matter settling on the bottom.

Science and Technology Log

Sunrise brought the morning launch of the AHI, Acoustic Habitat Investigator, once again. Scientist Joyce Miller and Jeremy Jones deployed the sonar research boat to 23 degrees 43.6′ N and 166 degrees 15.7′ West to map shallow areas of the ocean bottom. Throughout the morning and mid-afternoon, the ship, HI’IALAKAI, resumed running benthic habitat mapping lines; filling in gaps around the reef from previous runs. Scientists onboard continued editing swaths of sonar data in the computer lab (dry lab). By 1630, the AHI was recovered in the southern work area and lifted back onto the ship using the cranes. Ship based TOAD camera operations began at 1800 as the sun was setting. The TOAD was set down in the water off the aft deck. The camera recorded images as the ship drifted. Images of coral, sand beds, and small fish zipped by on the monitors. Scientist Chojnacki, commented he would email me some of the images at a later date, since we couldn’t capture them any other way at the time. By 2300, TOAD camera operations concluded and the ship resumed benthic mapping around the outer circumference of the French Frigate Shoals.

Personal Log

I awoke from a much calmer night at sea and felt refreshed! The day was spent on the ship, interviewing members of the NOAA corps and crew. I also helped edit pixels of data for the multibeam sonar mapping project ongoing in the dry lab. The following interviews were conducted aboard ship on the bridge:

The four to eight watch shift on the bridge is conducted on a daily basis by Operations Officer Lt. Matt Wingate, ENS Sarah Jones, and ABS Gaetano Maurizio. Lt. Wingate is originally from Connecticut and is the Operations Officer for the HI’IALAKAI. Besides having watch duties on the bridge, he is responsible for collaborating with the lead scientist and CO to act as a go between to establish the P.O.D. (plan of the day) for each day at sea. He posts the P.O.D. around the ship every morning to inform all hands of the day’s activities. His job involves some paperwork handling and coordinating details. He comments that the best part of his job is that it is different everyday, and every cruise has varied goals. He enjoys the variety on the job but does admit being far from friends and family can be a hindrance in this line of work.

Like many other people onboard the ship, the lieutenant has an alternative sleep schedule. He works from four p.m. to eight p.m. as well as four a.m. to eight a.m. everyday. This type of schedule forces a person to sleep during daylight hours in order to get sufficient rest. Mr. Wingate possesses a bachelor’s degree in mechanical engineering and advises anyone thinking of a career in the NOAA corps (officer division) to obtain a degree in science to meet the requirements. It is also helpful to not get seasick in this field of work! The resources he uses the most for his job are the lead scientist and the computer. He will spend an average or 190 days at sea this year, usually in intervals of 3 weeks at sea and 6 days on land in a one month period. He is the third highest ranking officer aboard the HI’IALAKAI.

Ensign Sarah Jones was also present on watch this afternoon. ENS Jones is originally from Kansas and joined the HI’IALAKAI officers in June of last year. Her undergraduate degree is in meteorology, a perfect fit for the extensive weather data being collected everyday aboard the ship and NOAA’s objectives. Upon entering the NOAA Corps (the nation’s smallest and most elite uniformed division) she was given a three month hands-on course on driving a ship, using radar, Nobel Tec, and other various equipment located on the helm. Her responsibilities while on watch include the equipment on the helm, observing the depth sounders, using paper charts and the Nobel Tec system to see the ship’s course across the Pacific Ocean. She works with the scientists in the survey room (using walkie-talkies) to keep the ship on course, following established survey lines to fill in benthic habitat data needed for the scientific work being conducted onboard. She commented that the perks of her job include the travel and dive training, and the worst part is the occasional sea sickness she suffers from. Patience, situational awareness, and the ability to multi-task are all traits ENS Jones believes someone should embody to perform well at this type of job. Her current assignment will be approximately two years at sea, then a three year land assignment. After accruing years with NOAA she can then decide to go back out to sea or apply for positions in the aviation sector of the organization.

Lastly, I interviewed ABS Gaetano Maurizio. ABS stands for Able Bodied Seaman, which encompasses a myriad of responsibilities. ABS Maurizio originates from Molokai, Hawaii and was in the U.S. Navy prior to his current position at NOAA. He has brought with him knowledge of maritime search and rescue and fire fighting from his previous training in the Navy. His current job encompasses being a coxswain (steering the ship or a Zodiac boat), a deck hand (involved in any aspect on deck, including crane systems), preservation of the ship in emergencies (like fire fighting), and he also occasionally helps the engineering department with tasks as they arise. He comments the pay he receives in this job is encouraging and he enjoys the travel. Drawbacks include being far from friends and family for long periods of time. ABS Gaetano Maurizio reflects on the fact that someone should be mechanically inclined and react quickly to stress or emergencies to perform well at this job.

The ongoing interviews I conduct are helping me to better understand the interdependence between the officers, crew, scientists, and engineers aboard the HI’IALAKAI!

QUESTION OF THE DAY for my fourth grade students: Multiple Choice! The ocean floor is full of nutrients and food particles resulting from___________________. a) tornadoes. b) water currents. c) salt water. d) decaying matter settling on the bottom.

ANSWER TO YESTERDAY’s Question: All living things in an area, together with their environment, is called an ecosystem.

Science and Technology Log

The AHI (Acoustic Habitat Investigator) research boat was once again launched from the decks of the HI’IALAKAI this morning with scientists Joyce Miller, Joe Chojnacki, and Jeremy Jones aboard. They set a course for 23*43.6’N and 166* 15.7’N. Their daily ritual involves mapping the sea floor using multibeam sonar technology (sound waves) in more shallow areas than the ship can pass over. While those persons were out to sea, editing of swath data continued in the onboard computer lab and the lead scientist worked out some data involving conductivity readings. After lunch, the HI#1 10m speedboat was launched from the HI’IALAKAI to shuttle another scientist out to the AHI in a swap. (The AHI is a small research boat and isn’t really suited for more than 3 people at a time). The CO, (Commanding Officer) and other members onboard accompanied scientist Kyle Hogrefe out to check on a buoy nearby and they then went scuba diving at La Perouse Pinnacle.

The ship resumed shipboard mapping throughout the afternoon. Around three o’clock PM, the AHI and HI#1 boats were recovered and brought back on board. Later that afternoon and into the evening, scientist Joe Chojnacki began Trackpoint II testing over the side of the ship. Finally, about seven o’clock p.m. the TOAD was fed on a cable line overboard for preliminary testing. TOAD stands for Towed Optical Assessment Device. Basically, it is two cameras and lights attached to a metal apparatus, which is used to ground proof the acoustic data that has been collected by the sonar systems. To break it down even more simply, the sonar system creates data in number form, about the ocean floor, which is then translated into colorful dots of data and made into a map. The sonar detects different heights of the sea floor, including atolls, pinnacles, and such.

The TOAD is a camera system which records pictures of the ocean floor to reinforce the data collected by the sonar system. The TOAD feeds real time images on film through its cables directly into monitors in the dry lab onboard the HI’IALAKAI. While testing proceeded last night, myself and a few others gathered around to see images on the monitors of the sea floor below us. We saw huge table coral and fish swimming below. Benthic habitat mapping proceeded throughout the night.

Personal Log

I spent most of the day recording weather readings, interviewing three more scientists on board, editing data, and watching video from the aforementioned TOAD system. It was exciting to see the ocean floor teeming with life right below our massive ship.

Joe Chojnacki was interviewed today. He is a graduate student at the University of Hawaii, studying geomorphology. Joe is originally from Wisconsin, but grew up living overseas, the son of two teachers who taught abroad. His main responsibility on this cruise at sea, is to deploy the TOAD (towed optical assessment device) and assist with any diving operations on board. His work is primarily filming underwater to substantiate data being collected by the multibeam systems. He has also done work towboarding, an operation in which two divers are pulled (towed) below the surface to scan the ocean floor for debris or bottom type, for further investigation. He enjoys his job and graduate school work because he gets to help solve the puzzle about underwater geography and he is also getting to learn about other facets of the work, like sonar mapping and data editing. The tools he uses most often are the computer, dive and TOAD equipment, as well GPS systems (global positioning systems). He will attend one cruise out at sea a year while taking classes. Mr. Chojnacki comments that a person well suited for this type of career needs to be willing to take risks and be well motivated because it is a difficult lifestyle and not very well paid. There are no well defined career paths, so one must be willing to take opportunities as they arise, to persevere, and be curious about the things around them.

Sea floor mapping specialist, Alyssa Aaby is also onboard for this cruise. She originates from Portland, Oregon and is enjoying her first post graduate job. Her duties involve editing data collected from the sonar and putting the information together into a map. Alyssa is also learning new tasks, like the onboard mapping involved on the AHI. She has been working in Hawaii since August for HMRG (Hawaii Mapping Research Group), which is supported through grant funding by the University of Hawaii. Ms. Aaby has an educational background in environmental science and a graduate degree in GIS through Oregon State. She believes the best part of her job is getting to learn new tasks, like coming out to sea to help collect data while traveling across the Hawaiian Island chain.

Because she spends a majority of her time in front of a computer, she believes the long stretches of nonhuman interaction in front of the screen can sometimes be a drawback in this type of career. She credits a college advisor for helping her narrow down her career path and she believes that anyone interested in this type of career needs to take the path of a computer programmer in their studies. An ability to take an image and rotate it in your mind is also important. Alyssa works 9-5 hours while in her office on land but will travel to sea 5-6 times this year to visit places like Fiji and Papa New Guinea.

My final interview of the day was with Coral Reef Ecosystems Specialist, Jeremy Jones. Mr. Jones is originally from Indiana but has spent the last four years here in Hawaii. Like Mr. Chojnacki, he has worked as a towboard specialist, and has had jobs working in aquariums, a vet technician, and marine debris specialist. He possesses a bachelor of science degree in marine science and credits a high school library advisor with helping him to narrow down his field for college studies. He believes the travel is the best part of the job, and even as a teenager, he enjoyed studying the stars up above and the ocean down below. He has many responsibilities on this cruise; to include the repair and maintenance of the AHI research vessel, assist in dive operations, as a coxswain (driver of the AHI boat), and he is learning more about the collection and editing of the sonar data. Mr. Jones admits that this type of job has a “hurry up, and wait” mentality about it. In other words, someone who is interested in this type of career needs to understand that you must be flexible, think quickly in times of emergency, have infinite patience, and be a people person. You need to be able to adapt to living in close quarters with other people. Mr. Jones will spend 5-6 months at sea this year.

The interviews I have conducted have made me realize the infinite number of occupations in this area of science and I am looking forward to my future interviews this week.

QUESTION OF THE DAY for my fourth grade students: Multiple choice question! All living things in an area, together with their environment, is called a (an) ________________________. a) marine habitat b) ecosystem c) continental shelf d) gulf stream

Science and Technology Log

Today’s operations involved launching the AHI once again, with 3 scientists onboard, to do more benthic habitat mapping around the more shallow areas of the French Frigate Shoals. Mapping operations were cut short early today for a little rest and relaxation for the crew, scientists, and some NOAA corps members. Around two o’clock pm, the AHI was recovered and the ship launched speedboat HI#1 with 7 members of our ship to Tern Island for a barbeque. Tern Island, as mentioned in previous logs, is a bird sanctuary run by the Fisheries Service of the Department of Interior. In has anywhere from 6-14 personnel at a time counting, tagging, and collecting data on reproductive rates of bird species on the island. The scientists and volunteers on Tern Island invited the HI’IALAKAI for some rest and good food, in turn for a tour of the ship. After the first shuttle was launched, it brought back 4 members of Tern Island to take a tour of the ship, and it then turned around and took 10 more of the crew to the barbeque. The shuttle ran all day, some members of the HI’IALAKAI also went fishing instead of visiting Tern.

At Tern Island, a tour was lead by the manager of the sanctuary, and after a feast of hamburgers and hot dogs and the like, we were lead on a snorkeling trip on the north side of the island. We were careful not to disturb the birds, and entered the ocean to snorkel the underwater ecosystem. Other scientists, Corps officers, crew, engineers, and myself, dove below the surface to see several colorful fish, a small whitetip reef shark, sea slugs, sea turtle, and a submerged barge. It was very clear and the inhabitants of the reef ecosystem were easily seen. The last shuttle returned to the ship around 6:30 p.m., and data editing and sonar mapping resumed on board.

Personal Log

After breakfast this morning, I typed logs and answered email. By mid morning, I helped the chief engineer, below deck, do engine room check of all the machinery below. He showed me how to check the temperature readings and gages on the engines and systems. This type of check, is done three times a day to make sure all machinery is running smoothly. Where there were no gauges to be read, Lobo used a Raytek Thermal Sensor gun, to take readings through pipes. Next, I ate lunch and prepared for the trip to Tern Island. I borrowed snorkeling gear from several members of the ship and embarked on another great adventure. I never thought I would have had so many chances to see the underwater ecosystems of the Northern Hawaiian Islands while out to sea. It is wonderful to explore underwater, and it is new and different every time. The water was particularly clear near Tern and I took pictures of things like brain coral. Its name stems from the fact it looks like a brain and it was a bright green color. I also took pictures of the birds, like the albatross, concentrating this time on recording images of their adaptations (like beak shape and feet formation) to use in later lesson plans. It was a wonderful day and the snorkeling thoroughly wore me out by day’s end.

QUESTION OF THE DAY for my fourth grade students: Use a reference source. 1) What is the name of the wettest place on earth? (Hint: it somewhere in Hawaii.) 2)List the name of the reference source you used (this includes websites remember!) 3)The annual average rainfall of this place is 661 inches a year. How many feet of water is that?___ How many yards?____

ANSWER TO YESTERDAY’S Question: If the ship rolls 9 times in one minute in 1-2 foot seas, how many times will it roll in one hour? 9×60=540 times How many times will it roll in one 24 hour period? 24×540=12,960 times! Imagine how many times the ship rolls when there is a storm at sea!

Science and Technology Log

At approximately 7:45 this morning, the AHI (Acoustic Habitat Investigator), research boat was launched from the side of the ship using the crane system. Three scientists were onboard to continue mapping the ocean floor using the sonar system attached to the bottom of the AHI. This work would take them until four o’clock this afternoon. Meanwhile, back on the HI’IAKALAI, the NOAA officers on board led meetings on safety and concerns, etc. with the crew and department heads.

The meeting lasted over 2 hours and gave the officers, engineers, and crew a chance to discuss problems, vent frustrations, and get routine meetings finished. The scientists were not involved in those meetings so the dry lab was full of scientists processing data from the ship’s onboard sonar system. I helped edit data swaths (lines of data collected about the ocean floor) for several hours. It is interesting to note that the data that is collected from the multibeam sonar systems is information portrayed in number form. Those numbers are then represented on the computers screens as various degrees of color, depending on the depth of the ocean floor. Data is taken out that lies outside the path or swath ( it is as if the ship is “mowing” lines across the ocean to gather because data like noise pollution is sometimes recorded (noise pollution can involve school of fish, etc.).

This day involved many people just sitting in the computer lab using their laptops to combine data into tables and mapping pictures. As the afternoon progressed, the AHI came back to the ship and was hoisted aboard once more by the cranes. CTD (Conductivity, Temperature, and Depth) casts were made twice throughout the day. The ship stopped to put the CTD device in the water and measure for this information. The information was used by scientists to verify their sonar data. Conductivity refers to salinity of the ocean water. The ship continued to run benthic habitat mapping lines all day long.

Personal Log

I spent the day in the dry lab (computer lab) for the most part. I edited data for the scientists and interviewed three people on board. I interviewed Commanding Officer Scott Kuester, ENS Amy Cox, and GVA Greg Wells while on their watch on the bridge. Their watch schedule consists of four hour shifts on the bridge, watching the sea, recording weather data, and communicating with all hands about operations on the ship. Commanding Officer (CO) Kuester is originally from Michigan and has been sailing for twenty years. His background involves a degree in U.S. Merchant Marine and he told me if someone is interested in a career in the NOAA Corps, they need to possess a bachelor of science degree. Related fields in calculus and physics are also helpful. CO Keuster has sailed may places including the Indian Ocean and the Gulf of Mexico. All NOAA Corps employees have rotational land and sea assignments and there are 5 NOAA officers aboard this ship. Current assignments aboard this ship last for 2 years and then a land assignment will occur for a few years. The CO has had land assignments in Silver Spring, MD at NOAA headquarters. His overall responsibilities are to stand watch as needed, and he has the responsibility of insuring the safety of the ship and all those onboard, as well as working with the lead scientist to ensure the scientific mission is completed for each cruise. The ship also collects environmental data on the weather at sea, which is used by federal agencies.

CO Keuster gave me an overview of many of intricate devices on the ship’s bridge, including the state of the art radar. I learned new terms like dead reckoning and nautical miles. Commanding Officer Scott Keuster recommended that anyone interested in a career in the NOAA Corps, should use their experience in college to gain more knowledge about computers. Diving knowledge is also helpful. In his opinion, a person for this job needs to adapt easily to stressful situations, know the meaning of teamwork, should be professional, and be able to live amongst others in close quarters.

I also interviewed ENS Amy Cox, the newest Corp officer to the ship, and GVA Greg Wells. ENS Cox is also originally from Michigan, and has training through the NOAA Corps as well as B.S. and B.A. degrees in Chemistry and Zoology. She has worked in Alaska aboard ships for the fisheries department; estimating catch of certain species, and population and reproduction rates of fish in that area. She enjoys her new sea assignment here in Hawaii and as an ESN she is responsible for using charts and GPS to map track lines, collecting weather data, maneuvering the ship, and for ship’s morale (by running the ship store, providing movie selections for broadcast at night, etc.)

GVA (General Vessel Assistant) Greg Wells also spoke to me while on watch. His permanent home is Myrtle Beach, South Carolina and has worked for NOAA for 4 years. His previous occupation was as an EMT in Seattle, Washington. NOAA has provided him with training like Bridge Resource Management and licensing courses. He will spend roughly 200 days at sea this year working for NOAA and while onboard, has responsibilities of driving the boat, operating cranes, machinery, and CTD operations.

It was exciting to stand on the bridge with them at night. The bridge was completely dark except for the glow of the red lights from radar and machinery. The ENS and GVA also went through a series of very ritualized, historic direction language as they maneuvered the ship into mapping lines. The bridge has to be kept dark so that watch standers can see out into the ocean for any changes or danger that lies ahead.

QUESTION OF THE DAY: My cruise along the HI’IAKALAI has been fairly smooth so far, but keep in mind that the ship rocks back and forth (called rolling) all the time. If the seas (waves) were to get rougher the ship would roll port to starboard (left to right) and it might also begin to move up and down, which is called pitching. If the ship rolls 9 times in one minute in 1-2 foot seas, how many times will it roll in one hour? How many times will it roll in one 24 hour period?

ANSWER TO YESTERDAY’s Question: using a reference source find out more about the whitetip reef shark 1) list 3 facts about this shark: usually 5 feet long, diet includes lobster, crab, eels, reef fish cave is used as a habitat 2) list the name of the reference source you used: Sharks of Hawaii by Leighton Taylor 3) draw a food chain for the shark like this example: white tipped reef shark—-(eats)-> eel(eats)—->reef fish
