Science and Technology Log
The purpose of our mission aboard the Henry B. Bigelow is the 1st leg of groundfish surveys from Cape May all the way down to Cape Hatteras with the Northeast Fisheries Science Center. The scientists aboard the ship are interested in both the size and frequency of fish at different targeted geographic locations. We will be sampling using a trawl net at about 130 different stations along the way, some inshore and some offshore. We will be using a piece of technology called the Fisheries Scientific Computer System (FSCS). This system will allow us to accurately take baskets of different species of fish and code them for their lengths into a large database. This will give us a snapshot of fisheries stocks in the Northeast Atlantic by taking a subsample. The computer system also allows us to see if any other things need to be done with the fish once they are measured. Tasks like otolith (I’ll tell you about these later!) and gonad removal, fin clips or whole organisms sampling may also be done. The computer system will allow us to label each of these requests and assign it a code for scientists requesting samples from this cruise. Additionally, there are scales along with the system for recording necessary weights. We will be sorting fish first by species, and then running them all through the coded FSCS which you can see in the photo below.
We are currently on full steam to get our first tow in early tomorrow morning. You can track our ship using NOAA’s ship tracker system. Here we are positioned currently passing Block Island.
Can’t wait to tell you more about the FSCS system when we start using it tomorrow!!
Personal Log
We have just pushed off the dock at 0900 and are headed South to start our first trawl tomorrow morning. Everyone is getting used to the ship and some swells with a few storms in the Atlantic. I am really excited to get to see what comes up in our first tow. I have been assigned to the day watch which means that my shift runs from Noon-Midnight. The two other ladies that share our room will be on the night watch, so there will be a changing of the guard and some fresh legs and recorders.
I am looking forward to bringing you some cool fish photos soon! Hello to everyone back in Bermuda! Stay safe..
Bye for now!!
