Deploying a drifter buoy
Last night I couldn’t sleep. I still saw my glow-in-the-dark alarm clock at 1:15am. I guess I was looking forward to waking up in the middle of the night to deploy the drifter buoy. It was 5am and it was time to go. It was still dark and I put on my float coat, gloves and hardhat. We went to the stern of the ship where it was lightly snowing and set up the drifter. I was able to write on the side of the drifter! 🙂 Key Biscayne Community School is now being represented in the Bering Sea! Of course I drew a Green Sea Turtle for Jonah on the top!A drifter buoy floats on the surface and is tracked by satellite. Some drifters make observations of currents, sea surface temperature, atmospheric pressure, winds and salinity. The ball floats on the surface of the water. It is attached to a wire that is 40 meters long and attached to a holey sock drogue, which looks like a tunnel Jonah would play in. They usually are active for 3-12 months. This particular drifter will just be tracked only by location because we are placing it close to large amounts of larvae pollock to determine where they are headed. Usually they are headed closer to shore. Once I return home I will be able to track it for our science class. We hope to deploy two more on this trip. The water got much rougher tonight. Using two hands to hold on while going up and down the stairs. Headed towards the Pribilof Islands tomorrow.
