Sorry for the delay in blog posts. Ever since we started heading for the Bight Fracture Zone, I’ve been busy with the onboard work, and it’s been quasi rough. That is all behind us now, as we are safely tied up to the dock in Reykjavik, Iceland. Cruise kn221-02 is officially over, and my colleagues […]
Well, it finally happened. The unusually fine weather we had for nearly three weeks came to an end last night as a moderately strong low pressure system swept by us. The winds picked up, as did the seas, and the shampoo bottle — my highly sophisticated barometer -tumbled over as the Knorr pitched and rolled […]
Not the greatest day today. I had been hoping to deploy another of my sound source moorings, but at the last minute it didn’t work out. Since we added this side trip toward Greenland, I had an opportunity to re-position a sound source mooring that was actually scheduled to be set during the next OSNAP […]
Late last night, we finished our second transect along our part of the OSNAP line. At the cruise outset, we transited from west to east (from off the coast of Greenland to Scotland) laying down about 20 deep-sea moorings. Then we turned right around and re-traced our steps, this time using the CTD package to […]
I finally climbed into my bunk this morning at 5 AM, after 20 hours without sleep. There was a break in the RAFOS float deployments—a chance to get a little rest. I dozed off right away, inspite of being rather jazzed up by all the stress of choosing the right float release positions. But just […]
We’ve just started the busiest portion of this cruise for the RAFOS float program. Today we have released the first 2 of the 10 deep floats that will sink to near the sea floor and drift with the currents there for the next two years. It is very tricky to find the best positions for […]
On Saturday, we reached the eastern-most point of this expedition, just a few 10s of miles off the western coast of Scotland. We could almost hear the bagpipes ! Our Scottish colleagues, led by OSNAP principal investigator Stuart Cunningham, deployed the last of the moorings–a trawl-resistant frame with an acoustic Doppler current profiler, or ADCP, inside. […]
One Ocean Insight blog reader remarked recently that he found it so funny that there was an oceanographer that used Jaws! I had never made that connection myself, perhaps because what I study is not what most people think of as oceanography. What do you think of when someone says “oceanography”? According to my unscientific […]
We are slowly getting closer to the Scottish coast, the eastern end of our “line”. We have just 2 or 3 more moorings to deploy before we turn back west and re-trace our steps, or maybe more accurately, our wake. The air and water temperatures are warmer here – almost 60F! A heat wave! It […]
I took the weekend off from blogging, but that doesn’t mean that science stopped on Saturday or Sunday. Our work continues almost 24 hours a day, 7 days a week. Research vessels like the R/V Knorr are so expensive to operate that once we are at our work site, we need to keep moving along […]
