Science and Technology Log

Last night we sailed south/west and this morning we are off the coast of the Alaska Peninsula in the vicinity of Katmai National Park. According to Carol Dewitt, one of the supervisors on this leg of the project, there have been an inordinate number of lost moorings on the GLOBEC line as compared to other moorings in this area. It has been suggested that this could possibly be due to long-line fishing interference but no definitive cause has been determined as of yet. Today we will recover and deploy another buoy and continue in a south westerly direction.

Personal log

Last night during my nightly visit to the bridge I discovered that the crew was closely observing 2 lights that were directly in our path. The concern was that they could possible be marker buoys for a long line and if we were to cross the line it could become entangled in our propeller. Fortunately the lights turned out to be a small boat and a marker for some rocks called “latex rocks”. There is only one captain (John Herring) on this boat and he cannot be on watch 24 hours a day. Often the driving of the boat is turned over to the other crew members including the XO (Executive office) as well as other less senior personnel such as the ensigns. After watching them all work I have complete confidence in their abilities, dedication and attention to detail.

Question of the day: What is long-line fishing and how is it impacting our fisheries? What regulations have been put in place to try and reduce negative impacts of long-liners?

Science and Technology Log

Yesterday we failed to retrieve the buoy that had lost its floaters but we did successfully deploy a new buoy. During the night the boat sailed south west to our present position off the coast of the southern end of the Kenai Peninsula. This morning we deployed another buoy and took CTD readings. We have one or2 more buoys to recover and deploy and they we will be picking up several buoys that will not be replaced because their projects have completed.

Personal Log

Last night at around midnight, the ship finally got an hour of down time and I got to fish. No one else was much interested so I was out there on the stern of the boat in the middle of the night watching the sea birds and hoping for a bite. I got to thinking about all the different types of birds out here and all their different strategies. Some stay here year round while others migrate to warmer waters and return.

Question of the day: What species of Plover migrates between Hawai`i and Alaska. Illustrate the migration patterns and summarize how those patterns have been elucidated.

Day 4: Monday, April 12, 2004

Latitude: 59.31.830N
Longitude: 149 10.28’W

Weather: clear Visibility: 29.5-49.5 ft (very high)
Wind direction: 355 degrees
Wind speed: 6 (m/s)
Sea wave height: virtually flat
Sea level pressure: 143mb
Cloud cover: Nimbostratus

Science and Technology Log

This morning we are off the coast of Seward. We have been having difficulty retrieving a mooring because it is not vertical in the water. At the base of the mooring there is a switch that releases the mooring from the anchor by remote control. The switch also has a sensor that tells the ship what the position of the mooring is. Apparently the mooring is horizontal in the water rather than vertical and that is likely the reason why we cannot
find it. The boat will return with a remote rover that will find and retrieve the mooring.

For now, we will continue on and get the next mooring which is closer in to the coast.

Personal Log

The seas are flat, the sun is shining and the coast is stunningly beautiful. We are close enough to land that I can see individual features. There is a very large coastal glacier directly inshore from us. I will try and look up the name of that glacier and report tomorrow on that.

Question of the day: What is the definition of a glacier? How are glaciers being used to track global change over geologic time?
