Science and Technology Log
Our day begins with calmer seas and some sunshine, the fog lingers, draped softly over the sea. We are making good progress in the number of stations sampled. However, there is word that a storm may be approaching on Sunday. We expect to be closer to the coastline by then, so perhaps we won’t feel the full brunt of the weather system. Wave action will determine if the dredge is deployed or not.
By late afternoon through tonight the winds have picked up again. Waves are pounding the ship as we move between stations. We’ve had some interesting catches today, mostly sand dollars with few scallops. But this evening we pulled up a large boulder! Then we had a catch with no scallops at all. Another dredge brought up a Windowpane flounder also known as daylight. If you hold it up to the light, you can see right through it! Another interesting specimen is the black rectangular egg sac of a Skate. You can see the embryo of the fish inside when you hold it up to the light as well. You just never know what‘s going to come up in the net. Yesterday I was talking about the green slimy secretion from sand dollars. Today Shad was telling me about Horseshoe Crabs. Turns out they have blue blood, the result of using copper to oxidize their blood instead of oxygen like we do!
In the few minutes that we have between stations, it‘s not unusual to hear the crew talking about their families and loved ones. Anecdotes shared accentuate the human factor in this service. Especially late in the shift, it’s fun to exchange stories about home. I’m back in my cabin ready to call it a night. As I lay in my bunk I feel the ship fighting against the waves. A funny thought occurred to me: the cabins are below the water! We’ve been sleeping “in the sea”!
