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.

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.

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!

Science and Technology Log

Here we are on Sunday afternoon and we’ve been anchored off Provincetown since Thursday evening to wait out bad weather and unworkable conditions. When the fog cleared, the view of Provincetown was quite pretty from the ship, but I have seen enough of it, and am ready for some adventure . Luckily, we set sail this evening and will begin our watch for right whales again tomorrow morning. While Monday looks to be quite windy, Tuesday shows promise as a good day for whale sightings. All the scientists aboard are anxious to get back to work!

During our down time I was able to interview two people aboard with very different jobs – Peter Duley, one of the NOAA scientists, and Margaret Coyle, the ship steward.

Peter Duley NOAA scientist

Peter Duley NOAA scientist

Peter has worked for NOAA for 10 years, and has also worked for The National Science Foundation. He has literally been to the ends of the earth doing research. He did his under graduate work at the College of the Atlantic in Bar Harbor Maine . Upon graduation  Peter did field work in Belize banding birds. While his first love was birds, he became interested in marine mammals and has done research work studying harbor porpoises in the Gulf of Maine, pilot whales in the mid Atlantic to the Gulf of Maine, bowhead whales in Alaska, right whales along the East Coast, and even spent time in Antarctica studying leopard seals. He now spends his summers on right whale survey cruises, and his winters doing aerial surveys of right whales.

While interviewing Peter I was struck by the passion and excitement he has for his work. It is obvious that he loves what he does and is very dedicated to saving the “giants of the sea”. All of the whales Peter studies are endangered and it is imperative  that scientists have a handle on the populations of these endangered whales so they can determine if the number of whales is rising or falling over a period of time, and what factors are influencing their survival. These scientists are so familiar with some of the right whales that they can identify the whales that have already been cataloged when they see them. They are cataloging all the whales using a number system that includes the year the whale was first seen, and another number that matches their mother if she is a whale that has previously been cataloged.

Peter’s favorite marine mammal is  the leopard seal.  He told me a story about the most dangerous situation he has been in while doing field work. He was in Antarctica in a small inflatable boat called a Zodiac and a leopard seal swam right up to the boat. He and his colleagues were excited and started taking pictures when the seal jumped out of the water and came down with its mouth on the side of the boat. The seal put a large hole in the boat. Fortunately, the boat had several different air compartments so the entire boat didn’t deflate in the frigid Antarctic waters, but Peter and his colleagues got back to shore as quickly as possible. My next question was, “What was your best research experience?” Peter said smiling, “The time the leopard seal put a hole in the boat!”

The other person I interviewed is Margaret Coyne, the ship steward. She  probably is one of the most important people on the ship because she keeps us all fed! Not only does she make three meals a day for everyone on board, we actually eat like we are at a 4 star resort. There is always an amazing variety of delicious food at every meal.

Margaret and her 2nd cook Tyrone  Baker, work 12 hour days from 5:30-6:30 with an hour break during the day. The galley is always buzzing with crew and scientists enjoying meals, snacks, leftovers, or anxiously awaiting for the homemade soup of the day to be brought out. There are always plenty of choices for all types of eaters – Margaret makes vegetarian options for each meal. She also makes her own yogurt, soy milk,  fresh salad, ice cream,  and a delicious dessert daily.

Personal Log

I will be happy when we start moving again and get back to the mission of surveying right whales. It has been difficult to be stationary for such a long time, but luckily, the scientists and crew are all so friendly that there is always someone to talk to. It is really interesting to learn about other people’s lives, and what brought them to where they are today. Hopefully I will remember this experience because of all the amazing whales I will get to see, but if not, I know I will carry fond memories of all the people I met.
