Day12: Tuesday, April 20, 2004

Latitude: 52.47.97N
Longitude: 168 55.95

Weather: continuous clear
Visibility: 29.5-49.5 ft (Very High)
Wind direction: 109 degrees
Wind speed: 16 (m/s)
Sea wave height: up to 8 feet
Sea water temperature: 4.1 Degrees

Science and Technology Log

Yesterday we tried to retrieve 2 moorings in the Alaska Stream but we couldn’t get a signal on the second one. Today we went back and tried again but still no signal. This could be do to a missing or damaged mooring. We will proceed to the next site and pick up another mooring and continue taking CTD readings on our way back to Dutch harbor. Projected arrival time is April 22 8:00 am.

Personal Log

The waves were up again last night and I am seriously looking forward to sleeping in a bed that doesn’t move. Tomorrow will be spent doing laundry, packing up equipment and generally getting ready to go into port. This is my last log for the trip.

Question of the Day: What is the Alaska Stream and how does it effect weather patterns?

Day10: Monday, April 19, 2004

Latitude: 52.10.107N
Longitude: 168 11.925

Weather: continuous clear
Visibility: 29.5-49.5 ft (Very High)
Wind direction: 391 degrees
Wind speed: 16 (m/s)
Sea wave height :approximately 5-6 feet
Sea water temperature: 4.1 Degrees

Science and Technology Log

We successfully retrieved the 4 buoys in Amukta pass. Today we will pick up 2 of the 4 buoys in the Alaska stream and do before and after CTD readings. Normally we could do all 4 data points in a day but the ocean is so deep that it will take excessive time to do the CTDs. Tomorrow we will get the other 2 buoys and from there we have buoys in

Samulga pass and then into port in Dutch Harbor. Currently the predicted arrival is the night of the 21st. 

Personal log

Last night we all tossed in our bunks looking forward to a bed that doesn’t move. So far I have been fortunate not to have sea sickness, but others have not been as fortunate.

Question of the Day: Describe the physiology of motion sickness including a detailed description of the inner ear. What is the structure of the inner ear that connects directly with the central nervous system? What are some possible causes of congenital deafness, what new technologies are being used to treat deafness and what defects can be treated with these technologies?

Day 8: Sunday, April 18, 2004

Latitude: 52.28.03N
Longitude: 171 10.7

Weather: continuous clear
Visibility: 29.5-49.5 ft (Very High)
Wind direction: 285 degrees
Wind speed: 35 (m/s)
Sea wave height :up to 16 feet
Sea water temperature: 4.1 Degrees
Sea level pressure: 1007.5

Science and Technology Log

The above data is from 0800 this morning. Last night the weather came up but we continued out to Amukta pass to try and recover 4 buoys. Unfortunately the waves and wind were too big for operations. This morning we are hiding on the lee of a small Aleutian island tucked in between 3 volcanoes (see attached photo) waiting to see if the weather subsides. We are scheduled to arrive in Dutch Harbor on April 21 or 22 so we can wait here for a couple days in the hopes we can grab those buoys because that is our priority at this point. So, no CTD’s were done and no buoys recovered

Personal Log

Right before bed last night I made my nightly visit up to the bridge. The waves were pretty big and it was fun riding them way up high on the bridge with the knowledge that this boat has been in much worse conditions during is decades of service. After I left the bridge the captain did report seeing “green” water which happens when the waves get so big that they hit the windshield of the bridge so far down from the peak that you see green water.

Day 9: Saturday, April 17, 2004

Latitude: 54.58.615
Longitude: 162.27.117

Weather: continuous clouds with drizzle
Visibility: 29.5-49.5 ft (Very High)
Wind direction: 181ees
Wind speed: 30m/s
Sea wave height: up to 20 feet
Sea level pressure: 996

Science and Technology Log

Last night we spent the entire night steaming south west down the Aleutian island chain, through the Unimak pass to the western side of the islands and past Dutch Harbor. Tonight we plan on picking up 4 moorings at Amukta pass and no new buoys will be deployed. The decision to move to the west side of the chain was made due to a small storm with 5 knot winds on the east side of the chain. If the weather improves we will move back over to the east side of the chain in a day or 2.

Personal Log

Last night I was awoken at 2:00 AM by some large waves that were tossing the boat (and me) back and forth. I kept thinking…”this boat has no centerboard” and “should I wake

up my roommate?” In the morning I discovered that my roommate was already awake and…this boat can take a lot more than what we saw last night. All of the tests are done with the centerboard up so we are still well within the limits of this boat. This journey has been an invaluable experience but I am very much looking forward to arriving in Dutch Harbor and seeing the wild horses that live there.

Question of the day: What are the factors that effect the formation of waves? How do the weather patterns differ between the Gulf of Alaska and the Bearing Sea

Day 7: Friday, April 16, 2004

Latitude: 55.11.03N
Longitude: 161 41.70

Weather: continuous clear
Visibility: 29.5-49.5 ft (Very High)
Wind direction: 125 degrees
Wind speed: 10 (m/s)
Sea level pressure: 24

Science and Technology Log

Last night we spent the entire night steaming south/west and this morning we are at Pavlov Bay where we will deploy a mooring. The weather report predicts 50 know winds which are too much for this boat to handle. The plan was to continue down the Aleutian island chain and pick up several moorings but if the weather turns out to be as predicted, we will come up with an alternative plan.

Personal Log

Last night we were in open water and the waves tossed us around all night. Both myself and my roommate got little sleep. Apparently though, the crew slept right through it. Today we are in very calm protected waters and it’s a sunny day with good visibility. We are working right in between Pavlov Volcano and some Aleutian islands and the contrast between the snow covered volcanoes on the starboard side and the relatively barren rock covered Aleutian islands on the port side creates a striking contrast.

Question of the day: Compare the formation process of the Aleutian volcanoes with that of the Hawaiian Volcanoes.

The larger volcano is Pavlov Volcano and the smaller one is Pavlov’s sister

Day 7: Thursday, April 15, 2004

Latitude: 57.40.47N
Longitude: 155 12.38

Weather: continuous clouds
Visibility: 29.5-49.5 ft (Very High)
Wind direction: 220 degrees
Wind speed: 11 (m/s)
Sea level pressure: 26

Science and Technology Log:

Yesterday afternoon we began to collect data on “line 8” which is a line that goes across the Shelikof Straight from Kodiak Island to the Aleutian Peninsula. This is a line of moorings that has been in place for many years. After servicing the moorings, we began transiting back and forth taking CTD readings. This operation will take approximately 24 hours at which time we will begin moving South/West down the Aleutian Island Chain. As part of “The Ring of Fire” The Aleutian Islands are volcanically active and they continue to erupt on a regular basis. According to one of the ship’s crew who has been on this ship for many years and has seen them erupt, these volcanoes are explosive unlike our Hawaiian Volcanoes. Personal log Last night the ship had a couple hours of down time and I got a chance to go fishing. No one actually caught anything, but I suppose that’s why they call it fishing. Although thousands of tourists and commercial fishers flock to Alaska every year to catch the many different species of Salmon, the fishery remains one of the most healthy and prolific in the country. This is probably due to the relative inaccessibility of much of the state in combination with strict regulations. Recently the practice of farming Atlantic Salmon

has increased, much to the dismay of conservation Biologists.

Question of the day: Describe how Atlantic Salmon are farmed and processed? What are the negative impacts related to the farming of Atlantic Salmon? Discuss potential impacts to wild populations as well as local impacts due to pollution.

Day 6: Wednesday, April 14, 2004

Latitude: 57.40.47N
Longitude: 155 12.38

Weather: continuous clouds
Visibility: 29.5-49.5 ft (Very High)
Wind direction: 220 degrees
Wind speed: 11 (m/s)
Sea level pressure: 26

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?
