Science and Technology Log

Today was our second full day of hauling and setting the traps. The science team is on a rotating schedule so that everyone gets a chance to work each position. Yesterday, I was a “runner”. My job was to stand in the pit next to the “crackers”. The crackers would take out the specimens and place them in a bucket and then take out the old bait and replace it with new bait. Once the pod was ready to go I would run the bucket to the lab and the pod (trap) down the pit tables to the stackers. It was a labor-intensive job, but at least I was able to see everything that came up in the trap. We did not catch many lobsters, but we did trap quite a few white tip reef sharks. Even though they are not very large they are extremely strong. I would know because I got to throw one over the side of the ship!

This is me in the pit when I was a "runner." So far we are catching more white tip reef sharks than we are lobsters. See the white tip on the shark’s tail fin? — This is me in the pit when I was a “runner.” So far we are catching more white tip reef sharks than we are lobsters. See the white tip on the shark’s tail fin?

Today I was a “stacker.” My job was to take the pods from the runner and stack them on the fantail, the back of the boat where the traps are released later in the day. The pods are stacked 4 high and end up covering the entire back of the boat. There are 160 pods all together. We release 10 strings of 8 pods each and 4 strings with 20 pods each. The main focus of the research being conducted is to collect data on the population of lobsters in the North West Hawaiian Islands. Even though we are targeting lobsters we record the data on everything we catch. Anything beside lobsters are considered by-catch. By-catch is considered anything that is caught accidentally. We are setting these traps for lobsters, but many times other animals will work there way into the pods. This is unfortunate for any fish that gets caught in the traps because they are pulled to the surface so fast that their air bladder expands causing a balloon-like structure to protrude from their mouth.

This is the feeding frenzy that follows the ship until the end of the day when we give them all our old bait. They are Galapagos Reef Sharks.

This “balloon” enables them to swim down and they end up being eaten by a predator or drowning. In a normal situation the swim bladder helps a fish regulate their buoyancy. The by-catch problem is seen in many commercial fishing industries. Usually they are dealing with a larger quantity of equipment and in certain instances, such as long lining, many sharks and turtles end up dying unnecessarily. The two main species of lobsters that are found in Hawaiian waters are the spiny lobster, Panulirus marginatus, and slipper lobsters, Scyllarides squammosus. Both species are also found in the waters off South Florida, but they do look a little different. The lobsters in Hawaii have more of a purple color to them. I have not come into much contact with them since my day in the lab isn’t for a while in the rotation. Once I am in the lab I will be able to report back with more information about them. Tomorrow I am a stacker again, so my biceps will be getting really big. I do know that on the first day we only caught 3 spiny lobsters and on the second day 21.

Oh! The most exciting part of the day is after we have finished hauling all the traps and replacing the old bait with new bait, we dump the old bait overboard and there is a feeding frenzy amongst the resident Galapagos sharks that follow our boat.

Personal Log

Here I am on the fantail of the deck scrubbing the mackrel blood after setting 180 traps.

Well my feet are very sore from being wet and in shoes all day. They are definitely not used to being in closed toed shoes everyday. I am ready to start working in the lab and learning more scientific information than just performing physical labor. With all the energy I am exerting I am definitely replacing all the lost energy with the delicious food that is different and amazing everyday. Today we had Hawaiian cornbread with pineapple. It was out of this world! We have also been eating a lot of fresh fish since one of the rotations included bottom fishing. I have yet to be in this rotation.

I am beginning to make friends with everyone on the ship. I am sure by the end of the month I will have forged some great friendships. It does seem like I have been on the ship for quite some time. I hope the days start going by a little faster. I am beginning to miss Florida!

I will be writing soon. Hopefully with some exciting adventures!

Science and Technology Log

Since the ship is still in transit to our first location the science team did not have much to do today. All we did was set the tables up in the “pit”. This is the section of the boat where the traps, or “pods”, are pulled up out of the water. Once they are pulled out of the water they are cracked open and everything is placed in a corresponding bucket to be taken to the wet lab to be measured and recorded. Everything in pod 1 would be placed in bucket one and so on. The only organism that does not go into the buckets are eels. My job today was to bolt the tables in the pit together. They needed to be bolted together in case we hit rough seas. While half of us were working on the tables the other half was inflating buoys that will be used to mark the beginning and end of a set of traps.

I also was able to release a message in a bottle that another teacher had sent to me before my trip asking if I would release it for him. The man, Jay Little, has had over 225 message bottles released all over the world. His goal is to raise awareness for the global efforts needed to preserve the integrity of oceans and inspire people to take action. The message in the bottle explains his goal and also asks that whoever finds the bottle to send him back artifacts from the location it ended up in. He uses these artifacts to make sculptures that reflect the contributions of people from around the world. Out of the 225 bottles released to date 21 have been found. The 19^th bottle found had an incredible journey having circumnavigated the world in 23,000 miles. The latest discovery was in Matrouh City on the Mediterranean coast of Northern Egypt in 2007. Hopefully our bottle number 285 will land somewhere new and deliver an important message.

Here I am throwing the message in the bottle over the stern of the boat.

Personal Log

One of the perks of being out to see are the incredible sunrises and sunsets that happen every day and the wild life that comes with it. In the morning a huge pod of either Pacific white-sided dolphins or Dusky dolphins, passed by the ship. They are very similar and some scientists believe that they might be the same species. In the evening, while on top of the bridge to watch the sunset, two red-footed booby birds decided to perch on the weather vain to watch too. They are the smallest of all the booby species and nest on land, but feed at sea. They are strong flyers and can travel up to 93 miles at a time and can dive up to 98 ft. to pursue prey.

The food is really good. Last night the cook made chocolate cake with a pecan and coconut frosting. It was very delicious. It is a good thing the boat has an exercise room so I can burn off the calories from three full meals a day. They also have a freezer that is stocked with ice cream and available 24 hours a day.

“Did You Know?”

Prior to the Revolutionary War, dockworkers in Boston went on strike protesting that they had to eat lobster more than 3 times a week!

NOAA Ship Oscar Elton Sette about to leave port

Science and Technology Log
Well the ship was originally supposed to depart on May 28, but first it experienced generator problems delaying the trip by two days and then there were problems with the salt water holding tank postponing the trip another day. The reason there have been delays with the ship is because the Oscar Elton Sette was originally made for the Vietnam War. It never did see any action, but it is that old. In preparation for the cruise we received a cultural briefing on the importance of the North Western Hawaiian Islands to the native islanders. The natives are very spiritual and believe that the souls of their ancestors travel to these islands.

After the cultural briefing, we went to the ship where we were given a brief tour and then loaded 6,000 lbs of bait. The bait we are using is mackerel. The chief scientist, Bob Moffit, informed me that mackerel is good for bait because it is very bloody and oily. Mackerel is considered a constant variable in the lobster study. This means it is something that stays exactly the same during each trial. If they used different bait during each trip they might not know if that affects their results so they keep it constant.

Personal Log

Since the trip was delayed I had time to explore the island of Oahu. My hotel was located in Honolulu, the capital of Hawaii. It is a very busy and somewhat crowded place. The population of Oahu is around 1million and the entire population of all the Hawaiian Islands is around 1.3 million. So it makes sense that it is a heavily populated area and it is usually the first stop for visitors from the main land, ex. Ft. Lauderdale!

This is my room that I share with four other women!

I rented a surfboard for an hour at Waikiki Beach and was able to catch a few waves even though the line up was very crowded. I also got to explore the North Shore and see all the famous surf breaks. While there I stopped at a little ice cream shop that had mochi, which is a Japanese food made from sticky rice. This shop just happened to stuff the sticky rice cake with ice cream and it was delicious. My favorite experience so far was hiking up to a waterfall in the forest. The scenery was very beautiful and when you reached the fall you could climb up and jump of a ledge into a very cold pool of water. I am on the ship now and everyone seems very nice. There are three other women who are considered part of the “science party.” We are all in a room together. The room is meant for six people, but there are only four of us so we have plenty of space and extra drawers for our belongings. I will write again soon!
