Personal Log

NOTE: We will arrive in the port of Dutch Harbor, Alaska on June 20. As the project draws to a close, I would like to evaluate how effective it was. There is a link to an electronic survey. I would like to ask students, teachers, parents, and other visitors to the site to take a few moments to let me know what you think of this idea. The survey is all electronic and only takes a minute or two to complete. Thank you in advance for your time. Click here to access the survey. I should be able to send one more blog tomorrow from Dutch Harbor. Check back and I will let you know what being on land again feels like. Dutch Harbor should be an interesting place.

We passed the Pribilof Islands. Home to one of the largest worlds largest gatherings of marine mammals in the summer time. I got up to see the islands at midnight and again when we passed a second one at 4:00 AM. We were covered in fog both times, so we will have to come back another day. At midnight, the sun had not yet set. Our sun set last night at about 12:15 and it took a long time to grow dark after that. The sky began to grow light at about 5:00 and it came up a little after 6. A short night.

Science Log

Last night we had another bottom trawl. This one had some of the largest sea stars I have ever seen. One was close to a foot long.  In addition, there is a coral here called sea raspberry. It is common along the Bering Sea Shelf. I thought coral was only in tropical seas, but here it is in the Bering Sea. Since it is our last day at sea, I spoke to our Chief Scientist Dr. Paul Walline from the Alaska Fisheries Science Center in Seattle Washington about what we have learned so far.

What does the data tell you so far? 

What do you expect to see in the next legs?

What will happen to the data at the end of the cruise? 

Finally, we were testing a platform today that can open nets at different depths. We lowered the platform to about 390 feet before a technical problem forced us to raise it back up to the surface. As an experiment of my own, I tied a bag of Styrofoam cups to the platform to see what the pressure at that depth would do to them. Want to see more? Click here for a video
