Our route in George’s Bank

Our route in George’s Bank

Yesterday was a 12 hour shift of towing the HabCam. The strangely unique thing about that was the terrain. We are on the western edge of Georges Bank and the sand waves on the ocean floor are incredible! There are waves as high as 10 meters that come upon you in a blink of an eye. By observing the side scan sonar it looks very similar to being in a desert, or on the surface of Mars. We refer to driving the HabCam through these areas as piloting the “White knuckle express”.

To get through these areas Scott was able to use geographic images collected by the United States Geological Survey and created an overlay of the pictures onto our tow path, alerting us to any possible hazards in navigation. This data allowed us to anticipate any potential dangers before they arose.

We continue to see skates, various fishes, lobsters and sand dollars, and in places, huge amounts of scallops. The images will be reviewed back at the lab in Woods Hole, MA. I have been able to see some of them and the clarity is amazing.

Today, we are continuing to tow the HabCam. When finished, we will have taken images from hundreds of nautical miles with over 4 million images taken on Leg II! We will put in the scallop dredge toward the end of my shift. We will then conduct back to back dredge tows on the way back to Woods Hole totaling over 100 nautical miles for this portion of the trip.

Personal Log:

Yesterday was a beautiful day at sea. It was, however, strange. The sea was really calm and the sun was shining in a big beautiful sky. The strange thing was that about 300 yards out was fog. There were many commercial fishing vessels all around us. It felt like being in an episode of “The Twilight Zone” or some creepy Steven King novel. I am thankful, however, for smooth sailing.

The crew continues to be awesome. We had flank steak and baked potatoes for supper last night. Lee, our chef, is amazing. Everything she makes is from scratch and there is always plenty. The only reason someone would go hungry on this ship is if it was by choice. Lee takes very good care of us! I have had ample opportunity to get to know others who share my shift. Mike, Jessica and I are science volunteers. Jon and Nicole are the NOAA staff along with Scott an associate scientist at WHOI( Woods Hole Oceanographic Institute) on the science team. We get along “swimmingly” and have fun banter to break up any monotony.

I am sleeping very well at night. I think it’s the rocking of the ship that lulls me to sleep. I think I will miss that when I get home. Funny, how at the beginning of this journey I was cursing the very waves that now rock me to sleep. The way the body adjusts is amazing.

I will be home in four days. This week has swiftly gone by. Although I miss home, I feel I will miss people from this ship and the experience of being at sea (minus the sickness!) My mind is already putting together science lessons for my biology classes this fall. I do, however, have three full days left on this ship and I plan to make the most of it. Keep checking the blog to find out what happens next on the great adventure in the North Atlantic Ocean!
