Science and Technology Log:
I thought I would end my trip on the Henry B. Bigelow with some fun facts!
Did you know?
The Fisheries Scientific Computer System (FSCS) is able to prompt the data recorders with all actions needing to be performed for a particular species. It is coded with unique barcodes for every sample taken. Back in the laboratory all scientists receiving samples can receive all the information taken about the given organism by scanning this unique barcode!

Did you know?
Science crew operating on the back deck are required to wear an Overboard Recovery Communications Apparatus (ORCA). This system if it is activated sends a signal by way of radio frequency to a receiver on the ship’s bridge. This system responds immediately to the ship receiver and has a direction finder to help locate the man overboard.

Personal Log:
It would take me hours to go through all of the amazing creatures we caught and surveyed on this trip, so I thought I would write some fast facts about some of my favorites! Enjoy!
Did you know?
The male spoon arm octopus has a modified arm that passes spermatophores into the oviducts of the female. Pretty neat stuff!

Did you know?
Stargazers, like this one, have an electric organ and are one of few marine bony fish species that are able to produce electricity.  This is known as Bioelectrogenesis. They also hide beneath the sand with just their eyes sticking out and ambush their prey!



Did you know?
This fish, the Atlantic midshipman, has bioluminescent bacteria that inhabit these jewel–like photophores that emit light! It also interestingly enough uses this function in fairly shallow waters!

Did you know?
Sea spiders like this one have no respiratory organs. Since they are so small gasses diffuse in and out of their bodies, how cool is that!

Did you know?
The flaming box crab, Calappa flammea, uses its scissor-like claws that act as a can opener. It has a special modified appendage to open hermit crabs like a can opener!

A female Atlantic angel shark like this one can have up to 13 pups!

Did you know?
Seahorses suck up their food through their long snout, and like the flounders I talked about at the beginning of the cruise, their eyes also move independently of each other!!



Did you know?
Horseshoe crabs, like this one, have blue blood. Unlike the blood of mammals, they don’t have hemoglobin to carry oxygen, instead they have henocyanin. Because the henocyanin has copper in it, their blood is blue!

Last but NOT least, Did you know?
According to the Guiness Book of World Records the American Lobster has been known to reach lengths over 3 ft (0.91 m) and weigh as much as 44 lb (20 kg) or more. This makes it the heaviest marine crustacean in the world! This one was pretty large!!

Weather Data from the Bridge 
Temp: 14.11 C
True wind: 11KT
Seas: 4-6 ft

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”!
