Science and Technology Log:

Current time: 1630 hours. We have been operating the HabCam since I came on duty at 1200 hours. It is interesting watching what the HabCam is flying over. Depending on the area, it might be littered with sea stars (a predator of small scallops) or it may be littered with hundreds of sand dollars (a food of ocean pout – ugly looking fish). In the case of sea stars, you won’t see many adult scallops, which, makes sense if the young ones are getting eaten. All in all, the research here is pretty straight forward. We are looking to see what predation is affecting the scallops, basically, food chains and habitat. On the side scan sonar, you can see past dredge marks from fishing vessels that have come through. We have passed over some old fishing nets, gear, a shoe, a can, odd things like that.

I have been “flying” the HabCam which is pretty cool. You need to keep the cam approximately 2.5 to 1.5 meters off the sea floor which can be a tricky thing to do. Fun, but tricky. While the cam is flying, the “co”pilot” is scanning images looking for various critters, specifically scallops. It can be a process that makes your eyes go buggy after about 1/2 to 3/4 hours so we switch off every now and then. This specific episode of the HabCam has been running for approximately 14 hours and has traveled about 177 nautical miles. That is a lot of sea floor!!

In approximately 35 minutes we will deploy the scallop dredge. The dredge will run for 15 minutes spurts. We will run six of them back to back. When the dredge comes up we will sort all the species into their buckets, count and measure the scallops, count and measure the fish, toss back the sand dollars, star fish and most often the crabs. The scallops that are two years old or younger we measure and toss back into the sea. The older scallops get measured, sexed, weighed and sometimes shucked. Word is there will be scallops for supper!

Personal Log:

I now understand what it is like to be in a washing machine with no end! I have not been able to blog prior to now because I have been spending a great deal of time in my bunk and in the head. My diet consists of saltine crackers and water. Occasionally, I can sneak in a piece of fruit, but not often. So far, this experience has not really begun yet. I have, however, been able to go 24 hours with no loss of stomach content. That’s a good sign, I hope. Sleep has been good and I feel rested (for the most part). The crew on the ship is awesome and I could not ask for a better chief scientist! Everyone was very understanding when I was sick and cut me slack for not being able to pull my weight. I think the crying helped soften them up. I was looking forward to big seas and water, not so much any more. I beg for calm seas and light winds. Perhaps I will be able to get some photographs of me working for the next blog, but until then, I will be happy with just keeping my lunch down!

Cheers!

  1. I would love to see video footage of you in action, Janet! Hope you’re on your way to getting your sea legs 🙂 Love you! Jenny

  2. Awesome, Janet…the description part, not the puking part. Hope you are feeling better soon and get to enjoy some scallops for dinner 🙂

  3. Hi Bam ~ OMG, awesome, awesome!! But is there a ship medic? Wondering why you have to endure sea sickness when medication & shots are avalable. Hope you’re doing better cuz feeling like you’re gonna die saps your fun on the mission. I am so proud of you & all you’re learning & the courage it takes to do what your doing. It’s so facinating!! Your info on you blog is excellent!! Luv you! ~ NJ
