We finished our third survey today and it was another great one! We started off the survey on the eastern side of Jeffreys Ledge to see what is out there, since we hadn't been there yet this year. Unfortunately, there wasn't much out there to see. It was a very quiet area with very few birds, a handful of harbor porpoise, and only one or two humpbacks in the distance. We did how ever get to help deploy a pop-up buoy for Stellwagen Bank National Marine Sanctuary. These pop-up buoys are acoustical recorders that sit on the bottom of the ocean recording every noise in the area such as whales, fish, and boats. When the researchers want to recover the buoys to be able to hear what they have recorded, they can use a remote signal to cause the buoys to float up to the surface. These passive acoustical buoys are very helpful to monitor areas when survey boats or plans are not able to be out there. To learn more about the pop-up buoys, and other acoustical buoys, you can visit Cornell University's website.
