After breaking the dredge yesterday, we were looking forward to a calm quite day of catching up with the multibeam survey. Throughout the cruise we have been at the mercy of the ice as to where we would be able to get survey data. Just about midnight, the ship moved into an area that had been previously too congested with ice to do good multibeam work. Today it was clear, so we went looking for seamounts.
What a surprise. As the ship made its back and forth tracks over the seafloor, a map of orange and yellow began to emerge on the monitors. We saw large circular structures randomly dotting an otherwise flat and uninteresting seafloor. At first glance, these looked like the bases of volcanoes that had the top of their cones completely sliced off. As the data continued to come in, it became apparent that the circles were not elevations on the seafloor, but circular depressions in the seafloor. It was time for speculation and hypotheses about their origin. We called this new area the Pepperoni formations.
Even though the ice had cleared, there was plenty of ice in the air. Snow settled on the decks of the ship adding just enough white to stir thoughts of snowball fights and snowmen. The snow blanketed most of the decks, except for the back deck that is the main work area for the ship. The back deck uses warmed antifreeze circulating in pipes under the deck to keep is and snow from accumulating. This helps keep everyone safe when working with equipment in the back deck.
Most of the morning was spent surveying the "Pepperoni" and then about noon we headed north toward Franklin Island. By 1:30 PM we had the dredge back in the water for the first of two dredges for the day. Each time we dredge we hope to bring up rocks that will give us information about the age and composition of the seafloor volcanoes that are focus of our dredge work.
The dredge came on deck intact and full of rocks. Jesse Doran positioned the dredge the over the work area on the back deck and reached into the top of the dredge and pulled out an ice fish over a foot long. Its mouth was open, with large round eyes, white gills and thing black body. He passed the catch of the day to me, and I held it as everyone took a look before heading to separate out the rocks from the debris.
As I held the fish, it moved slightly. I took it into the hydro lab and placed it into one of the sinks and filled it with seawater. Within seconds the gills were moving rhythmically, and then the fish began to slowly swim around the sink. Half of the people on the ship never see what is caught in the dredge because they are sleeping or nature of their work does not permit them to leave during their shift. Jenny White was able to locate a large glass aquarium and filled it with seawater. We placed the organisms that had been caught in the dredge in there for the night. In addition to the fish we had two large sponges and a starfish that was about seven inches from arm to arm. During the course of the night everyone was able to come and see the aquarium.
Over the course of the night, many small organisms moved out of hiding among the spicules of the sponges. There were worms, sea spiders, small snails that slowly moved out into the open. There were over a hundred small organisms that were calling these sponges home that we could see. The sponges were like a small forest that these tiny organisms lived in.
We continued the multibeam survey throughout most of the evening. The marine techs finished getting the guns ready for a possible deployment of the seismic sometime tomorrow.

He has a degree from the University of Georgia in education. He began working in Antarctica with black hair and now has gray. He is fascinated with the research and science that goes on here and considers Antarctica to be the canary in the coalmine for the world
He is married and has two chocolate labs. The brown bombers don't even know how to chase balls yet. His wife is studying to be a physician's assistant and is involved in a number of volunteer groups in Ashville, North Carolina. He got involved in computers working with the forest service and then worked into the IT field when he had been working on a recreational use study in the US. The reason that he is here in Antarctica is because he had worked with a person that had actually signed the Antarctic Treaty.
