Science and Technology Log 

Most of this watch will be spent steaming to the first southern station. Our ETA (estimated time of arrival) is 8:00 am.  We are planning to do a full station meaning CTD, Neuston, and a Trawl. It is midnight now and I am hoping to get an interview with our Chief Scientist prior to beginning the station.

The first Bongo is scheduled for noon. Dan Carlson, a graduate student at Florida State University, is aboard researching his master’s thesis. He is utilizing the water samples from the Bongo to learn more about the development and origination of red tides which bloom in the Gulf of Mexico.

I have just been put “in charge” of the Neuston for this station. That means I am responsible for seeing that the net is dragged for ten minutes, that the organisms which are gathered are washed down into the cod end and that the sample is then gathered are delivered to the plankton transfer table.

Personal Log 

The Chief Scientist has been actively engaged with data collection and correction activities. I understand that a server has failed and that all time/date information must be hand entered into all data sheets. This is time consuming but very necessary for the sake of accuracy.

Question of the Day 

What is red tide?

Answer: It is an organism, named Karenia Brevis, which produces a neurotoxin which, in turn, is toxic to virtually all sea life.

Science and Technology Log 

There will be no fish caught today. The OREGON II is steaming to port in Galveston. One of the two radars has failed. The ship is required to have two functioning radars in the event that one should fail. Therefore, we must return to port and make repairs.

When the radar was lost, we were underway to the tip of Texas, off the coast of Brownsville, to begin surveying in preparation for the Gulf Coast shrimping season. We expect to make port this afternoon and get underway south again sometime Monday.

Personal Log 

I don’t mind having this time off from the fish. Part of my mission is to write lesson plans that correspond to the activities aboard. This will give me time to work on the plans.

Question of the Day 

What does the radar do?

The radar serves as a set of electronic “eyes.” It recognizes obstacles in the distance so that they can be avoided by making necessary course corrections.

Science and Technology Log 

This watch began, again, with fish waiting on the deck. We processed that catch just as we had all the others. While we were processing, another catch of fish were being collected. A CTD was also performed. When the fish catch has been processed, it is necessary to return the processed organisms to the sea. There is a shoot in the wetlab designed for this purpose. The shoot has not been working properly so far on this cruise. During our watch it backed up completely. Water was rising up through the drain in the floor. Clearing the blockage took several hours.

The catch was sitting on the deck and we had no reason to believe that we would get the shoot clear any time soon. The Watch Leader elected to process the catch “dry” so we separated and identified the species without the benefit of water to clean the organisms. Following this catch, the shoot was cleared and the lab was cleaned. We are now making our way south to assess the Texas Gulf Coast shrimp prior to the beginning of their season..

Personal Log 

What a mess! Each organism had to be dipped into water just so that we could be sure it was identified properly. We found hundreds of little shrimp that are not even harvested for food purposes.

Question of the Day 

Where do the shrimp live?  Answer: In the mud on the bottom of the sea.

Science and Technology Log 

Tonight we began with a Neuston. Now I know that a Neuston is a rectangular frame to which has been attached a “sock” style net with a round portion at the bottom known as the “cod end.” The Neuston drags at the surface and catches sargassum (sea weed) and also plankton. Why? I’ll need to find out.

Next we pulled in the Bongos. These are round shaped “sock” nets with cod ends. In the cod ends, plankton and other sea life are collected from either the bottom or a maximum depth of 200 feet. The “catch” from both the Neustons and the Bongos are placed into jars with formaldehyde as a preservative. Forty-eight (48) hours later they are transferred to alcohol. They are then shipped out for processing.

The CTD was performed to capture water samples and hydrological data. All of the information is assembled and accompanies the samples to the lab for processing. Finally, we weighed and sorted the catch. Each species is identified by its scientific nomenclature which means we hear a great deal of latin in the wet lab.

Personal Log 

OK, I’m not quite as confused now. I had a great night’s sleep. I am beginning to learn some of the scientific names and I have gotten my fingers onto the computers that record the data regarding the organisms we classify. I’ve started having intelligent conversations with people and I am beginning to make sense of the activities aboard the ship.

Question of the Day 

What is the purpose of collecting the organisms in the Neuston and the Bongos? Answer: Plankton data is part of a long-term study regarding trends in fish populations.

Science and Technology Log 

Today we began to off load gear and seven personnel onto Green Island, the main island of Kure Atoll, as well as the farthest west and last island in the Hawaiian chain.  This island did not experience any bird poaching or guano mining, but in 1960 it became a United States Coast Guard LORAN (long-range navigation) station.  The major features of the station were a barracks, a signal/power building, a transmitter building, a pump house, seven fuel tanks, a 4,000-foot-long runway and a 625-foot-high LORAN tower.  The only features remaining are parts of the barracks and the runway, which is unused and disintegrating. There is also a small pier that is being used by the researchers.  It is now a wildlife refuge under the jurisdiction of the Hawaii Fish and Game Department.

The island is heavily vegetated with not only shrubs, grasses, and crawling vines, but also several kinds of trees. Verbesina is now growing out of control and a landscaper is a part of this crew to eradicate this invasive species.  It grows so thick that it does not allow ground nesting birds like the Blue Faced Booby to utilize them.  It also poisons the ground so that other plants cannot grow where they have established themselves.

I should mention that this is not a quarantine island like Laysan, Lisianski, and Pearl/Hermes.  Too many invasive species had been brought in with the development of the station to warrant that designation.  One of the invaders is a crawling weed with half-inch thorns and easily goes right through your slippers.  When the women opened the barracks to check it out, it was filled with cane spiders on the walls and ceiling; and the floor was covered with a carpet of dead ants that the spiders had eaten.  There are also rats and at one time there was a dog, left there by a rescued shipwrecked crew.  However, it was eaten by a crew that was shipwrecked later on.  The atoll is notorious for shipwrecks.

I saw turtles and seals too.  In fact, I had to get out of the water several times because the seals would swim towards me to see what I was doing there.  We always had to steer clear of all the animals so as not to disturb them or have them become familiar with humans.

Green island is located on the inner side of a large ring of reef.  Within this reef, it is relatively shallow and outside the ring it is very deep; rough water on the ocean side and calm on the lagoon side; and sloping fine sand beaches on the inside and course and rugged on the ocean side.  The camp and pier are on the lagoon side of the island.

Most of the day I was a “mule,” carrying six months worth of supplies from the shuttling Zodiac to the spider’s nest (the barracks). Lots of thorns, soft fine sand, hot sun, but no ticks.

At the end of the day I was rewarded by being allowed to visit the “AHU” (alter or shrine) that the crew from the Hawaiian sailing vessel, The Hokulea, had built on a recent visit to this island.  It is located in a spectacular site on the wild ocean side of the island just up in a safe spot from the water’s edge.  It is comprised of several large coral heads comfortably arranged with a Hawaiian adze placed in the middle, inscribed with the title “NAVIGATING CHANGE.”  I was deeply moved!
