Sargassum and turtle tracks

There have been a lot of developments at Matura Beach of late. We’ve been keeping a close eye on Christie and Sharon, our nesting turtles. As we found out when we tracked Peggy two years ago, there is no guarantee a leatherback will make it through the entire cycle of nesting safely.

And this year, there has been an added challenge. Sargassum in unprecedented amounts has landed at Matura, making it next to impossible for leatherbacks to nest there or for any hatchlings to make it to the sea. This is a video of our friend Kyle from the Nature Seekers. You will see him walk directly over the beach and almost 60 metres (200 feet) onto what is normally the ocean, but what is now a dense mat of sargassum.

The next video shows how deep and strong the sargassum bed is as it withstands the slapping waves.

So it has not been entirely surprising that neither Christie nor Sharon have been seen at Matura. In good news, according to our satellite data, it seems that Christie nested last night. She landed a little south of Matura Beach at Fishing Pond.

Sharon, on the other hand, has finished nesting. She is heading north! We are amazed at how quickly she is going. This is the first time we will have ever watched a known “Canadian” turtle on this part of their journey. We can’t wait to find out what comes next.

Here is the larger map, where you can also see Beverly’s track. She’s going west—which may mean back toward us, ultimately. However, in what we might call typical Beverly style, she isn’t heading in a predictable way. You’ll note she’s swimming north at the moment. Sometimes I feel like Beverly’s our teenager-of-a-turtle. She’s endearing that way.

Peggy

Peggy was a leatherback turtle we satellite tagged on Matura Beach in Trinidad at the end of May last year. She was a “Canadian.” When we found her on the beach, she was wearing flipper tags that showed we had worked with her in waters off Halifax in July 2009.

Normally we only work with leatherbacks in Canadian waters. This was the first time we put a satellite tag on a leatherback on a nesting beach. It was exciting and the result of a collaboration with our friends Dr. Scott Eckert, the Nature Seekers in Trinidad, and CBC’s The Nature of Things. Many people have asked us about her since seeing the documentary CBC aired last week. (If you are in Canada, you can watch the documentary that includes Peggy here.)

This is a picture of Peggy heading back into the ocean after we satellite tagged her. It is dark because leatherbacks nest at night.

We had hoped to follow Peggy’s track as she migrated back up to Atlantic Canadian waters. As you can see, however, Peggy’s track only lasted for 35 days.

She returned to Matura Beach three times to nest after she was satellite tagged. The third time, the Nature Seekers team observed her and had the chance to photograph her. She looked great, as did her tag. She left after that third nesting and headed out to an area off Galera Point to wait out “follicle development.” Her behaviour was typical of a leatherback getting ready to nest again.

Then she disappeared.

There is a lot of gillnet fishing in the area where we last heard from Peggy. Leatherbacks are routinely accidentally caught in this fishery. We talked to a fisherman from that area, who talked to others in his community. Although none of them reported catching a leatherback with a transmitter on her, it is still our best guess that Peggy was accidentally caught in a gillnet and died as a result.
