Science and Technology Log
Days at sea begin early for the scientists aboard the Hi’ialakai. There are push-ups on the bow at 0630 (not mandatory), followed by breakfast at 0700. After breakfast, everyone meets outside on the deck at 0730 for a meeting about the day’s diving. Safety procedures are always reviewed during this meeting.
Afterwards, the divers suit up, get their gear together, and get ready to board small boats, which will take them to the day’s scheduled diving sites. The way the small boats are lowered into the water with their passengers and gear from the larger ship is nothing less than a carefully orchestrated ballet of synchronized movement, line management, and communication. The chief boatswain (“bosun” for short), the senior crewman of the deck department, is in charge of this process. You can see him in the first photo, operating the crane. Anyone on deck during this time must wear a hardhat for safety purposes. You would not want to get hit in the head with moving cranes, hooks, or cables!
First, the small boats are lifted from the upper deck with a crane and lowered over the side of the ship.
Then, gear and passengers are loaded onto the boat, and it is carefully lowered into the water. Lines are released. and the boat drives away.
After that, the coxswain, the driver of the boat, takes the divers to the first survey site of the day. As we learn in class, a very important part of any scientist’s job is to gather evidence and data. Three to four groups of divers in separate small boats will gather data from 5-7 different sites each per day. After this project is complete, scientists will have gathered data from hundreds of different sites around the main Hawaiian islands. At each site, they do fish counts and benthic (sea floor) analysis. They estimate the amount of coral present on the sea floor, and then list fish by their species and quantity. Each diver takes a clipboard with a waterproof piece of paper attached to it on which they record their data. They also carry waterproof cameras with them, as well as a small extra tank of oxygen called a RAS (Redundant Air System) that they can use in case their tank runs out of air.
After data is recorded for several different sites, the small boats return to the ship no later 1700, which makes for a very long day out on the water. Dinner is from 1700-1800, and afterwards, scientist divers head to the dry lab, where all the computer equipment is located, to enter the data they gathered on fish during their surveys.
While we were out at diving sites today, I had the opportunity to interview Jonatha Giddens, one of the divers on the boat. Jonatha is a graduate student at the University of Hawaii at Manoa. She has an undergraduate degree in coral reef fish ecology, and she is currently studying the effects of an introduced grouper (a species of fish that is not native to Hawaii) on the local marine ecosystem for her Ph.D.
What are your primary responsibilities? Being part of the fish team, scuba diving, doing fish surveys, and entering the data collected during the day into computer systems at night.
What do you love most about your job? Being on the water!
What kind of education do you need to have this job? An undergraduate degree in marine biology
Do you have any advice for young people interested in your line of work? Get involved with research as early as possible. Find out what kind of research is going on in your area, and volunteer. Do summer internships at places that are farther away. You learn so much just by jumping into it.
Jonatha followed her passion and learned all she could about it. Now she has won an award from ARCS (Achievement Rewards for College Scientists) for her work in conservation ecology. ARCS is a foundation organized and run entirely by women to encourage female leadership in STEM careers. Go Jonatha!
I can sometimes go snorkeling while the divers are completing surveys, as long as I stay far enough away from them that I do not interfere with their work (they do no want me to scare the fish away). I have to wear a knife strapped to my leg while snorkeling, in case I become tangled in fishing net or line (or in case there is a shark!). Again, it is all about safety on the Hi’ialakai.
Did You Know?
The underwater apparatus held by Raymond Boland in the above photo is a stereo camera. It is composed of two separate cameras encased in waterproof housing. When a diver uses it to photograph a fish, two simultaneous pictures are taken of the fish. NOAA scientists calibrate the images using computers to get an accurate measure of the length of fish.
chief boatswain – the person in charge of the deck department
coxswain – a person who steers a ship’s boat and is usually in charge of its crew.
benthic – relating to, or occurring on, the bottom of a body of water

Have you seen any whales,dolphins,or sharks yet? BTW, there is a Warriors parade going on in Oakland right now. There is a man riding a bike with all of the player’s bobble heads on the tire!
Have a good day Ms.Camp!
Winter is whale season in Hawaii, so I have not seen any of those. I have seen some spinner dolphins, a sea turtle, and lots of colorful fish. I am not too keen on seeing a shark while I am in the water! I will look at the parade in the Internet.
Well…. You are sort of protected if you see a shark. You have that knife attached to your leg. If I were a shark I would keep my distance. If you were any animal in the world what would it be?
I would be some kind of bird that flies long distances. I like to look down on Earth from above. It’s a good perspective on life.
i’m enjoying reading about your days at sea and the scientists. Stay safe, keep that knife close while you are snorkeling.
Thanks, Chris! Hope you are enjoying summer break.
Interesting and enjoyable reading. Such a unique experience to share and one that you will always treasure. Stay safe and see you in August!
Fantastic post really interesting for an aspiring marine biologist like myself! Thanks
