We finally had a right whale sighting today! It was a juvenile and was quite close to the ship. It was exciting to see it frolicking.  

Allison Henry, chief scientist, recently told me that over 70% of the right whales they see have entanglement scars. The scars are due to entanglement in fishing lines.

Sometimes teams of scientists with special training attempt to disentangle a whale. It can be dangerous work. The video below shows a team working to remove fishing lines from a whale in 2011. The scientists first need to attach the small boat to the whale with lines so they can stay with it while it swims until it exhausts itself.  Only when the whale is tired, can the team work to cut away the entanglement.

Watch  this video of a whale disentanglement.

The other hazard is that whales tend to rest and feed near the surface of the water in the shipping lanes, and can be hit by ships.

During the day, from 7am-7pm, the scientists take turns on watch. This means we watch for whales using “big eyes” which are giant binoculars. We spend 30 minutes on left watch, 30 minutes in the center, and 30 minutes on the right watch.  At the center station we record sightings and update the environment using a computer program designed for this purpose.

I visited the Wheel House on the ship today. This is also called the bridge, and is the control center of the ship (similar to the cockpit of an airplane). The wheel house has many controls that the crew needs to know how to use, and it takes years of training to be able to command a ship. I spoke with Commanding Officer Lieutenant Commander Jeffrey Taylor and Executive Officer Lieutenant Commander Michael Levine about the workings of the Gunter.

Auto Pilot

This is the wheel or helm of the ship. The Gunter is one of the last NOAA ships with this type of helm. The newer ships have a helm that looks more similar to that which you find in a race car. Although the helm is still used to steer the ship at times, especially when docking, the steering is left to the auto pilot  the majority of the time.

ARPA radar

I know some of you were concerned about how the officers could see to steer the boat in the fog. The ship has an ARPA radar system that shows where other boats in the area are in relation to our ship. The radar also shows the course our ship is taking and alerts the crew to anything that may be in the path of the ship.

Throttles

Throttles

The throttles control the speed of the ship. The maximum speed of ship is 10 knots which is about 12 miles per hour. The ship uses diesel fuel and it takes about 1,200 gallons of fuel to run the ship for a 24 hour period. At night they will sometimes shut down one engine which makes the ship go slower, but which saves about 400 gallons or $1,600 a day. This is one reason why we anchored for 3 days during the bad weather. The weather made surveying whales impossible so it didn’t make sense to run the ship during that time. The cost of running the Gunter is $11,000/day on average. This includes everything to do with sailing including salaries, food, etc.

Personal Log

I know that some of my first graders have been asking about where I sleep and eat on the ship. Below are pictures of my stateroom and the galley of the ship. Two very important places!

  1. Dear Ms. Lyte,

    How are you doing on the ship? I’m glad you are sleeping on the bottom bunk, the top bunk looks horrible!

    Love,
    Brendan M.

    • Hi Brendan,

      I agree, there’s no room up there! I saw 2 sei whales and a fin whale today! We are sailing to Newport Rhode Island now. Tomorrow I will become a land lubber again. It was fun to be a scientist for a while, but I prefer being your teacher. See you on Monday!

      Love,
      Ms. Lyte

    • Hi Chase,

      It was so nice to be back at school today. I missed you guys. It was also nice to see your dad. I’m glad he’s feeling better.
      I liked all the great questions you had today.
      Love,

      Ms. Lyte
