Turtle tracks are back!

Here is where our turtles are today:

2015_11_06_Map

In great news, the Canadian Wildlife Federation will be highlighting the tracks of four of our leatherbacks in an initiative called The Great Canadian Turtle Race, which they launched this week. It’s terrific coverage for sea turtles from an organization that is passionate about conserving wildlife in Canada. We’re really excited about it!

Back at the office

We’re gradually settling back into office life, packing away equipment and painstakingly transferring information from our field sheets to our database. Our sea turtle field season is over, although there are still leatherbacks and loggerheads swimming in Canadian waters. The leatherbacks will start heading south over the next month, instinct sending them towards the nesting beaches of Florida, the Caribbean and South America. (Unless, of course, they are Beverly last year, who decided staying north and travelling east made more sense. Remember this and this and this?!)

Here is a look at where our satellite-tagged leatherbacks are these days:

Riley and Lily Rose…and an update on our current turtle gang

Riley and Lily Rose have both been seen nesting in French Guiana! We’ve just heard from our friend Antoine Baglan, who manages the database for Association KWATA in Cayenne, French Guiana. (Antoine is also, incidentally, an amazing nature photographer.)

You know, of course, the story of Lily Rose, and why she is so special to us.

But do you remember Riley? Riley used to keep us up at night. She was one of the first Canadian leatherbacks that we tracked right into Cape Cod Bay, where she navigated the maze of fishing gear for many days. I remember Scott Landry, the director of Marine Animal Entanglement Response at the Provincetown Center for Coastal Studies in Massachusetts, reviewing one of the daily Riley updates we sent and saying, “Wow. This just gets worse.”

But she thankfully got out and continued to swim down the coast of the United States. Riley was kind of like Beverly. We had tagged her as part of the Great Canadian Turtle Race, and she behaved differently from the rest of the turtles we were following that year. You can see her track below in red.

And then after almost seven months of tracking, Riley’s tag stopped.

So we are thrilled to hear about her and to know that she is safe and nesting—and we are also excited to learn where she is from, which we didn’t know when we tagged her!

Below is an updated map on the turtles we’re following now. Beverly continues to entertain us with her track, looping around and down again now.

Look how far Sharon has gone! I love seeing her zip past all of those islands. You can see this in more detail in this map:

But it’s Christie we’re watching most closely now. She’s still in the nesting zone.

Her current location is off Toco point, which is a busy fishing area and the place where we lost contact with Peggy. Let’s hope she pulls a Riley and makes it through safely.

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.

Sharon joins the turtle crew

2015_05_29_map

And now there are three turtles to follow again.

Our friends at the Nature Seekers satellite tagged another “Canadian” turtle at Matura Beach, Trinidad, that we have named Sharon. She is the blue dot, just below Christie’s green dot.

Here is a closer look at Sharon’s movements over the last few weeks:

And here is a closer look at Christie’s track:

2015_05_29_Christie

Both turtles are hanging near the coast. As you may remember, leatherbacks nest several times during a season. The days between each nesting event are called the “internesting interval.” During this time, while the next clutch of eggs is developing, the turtles are typically close to shore and within about 100 kilometers of their nesting beaches.

The part about this normal behaviour that makes us uneasy is that the turtles’ chance of entanglement in fishing gear at this time of year is high. So we’re doing the only thing we can: crossing our fingers and hoping that Sharon and Christie stay safe.

We’re also keeping an eye on Beverly, whom you may have noticed has turned and started swimming west again—perhaps on her way back home.

Nothing short of AMAZING!

Christie is BACK!

The turtle phone rang at 12:30 this morning.

It was Kyle, from the Nature Seekers in Trinidad.

“Unfortunately, we have good news and bad news,” he said. “The good news is Christie is alive and well. The bad news, she doesn’t have the transmitter attached.”

Francis, another one of the Nature Seekers, had been finishing up an ecotour with a crowd on Matura beach when he walked by a leatherback hauling up on the sand. One of the tourists asked how much bigger she was then the other turtle they had just seen nest. Francis went to check her out when he noticed she had a distinctive, transmitter-sized patch on the centre of the carapace.

This patch is one of the things the beach crews in Trinidad were looking for. We have learned over the years, that when a transmitter comes off a turtle, the skin directly under it is light in colour. Within a few weeks, the skin will darken again.

Francis raced to check the turtle’s flipper tags and radioed Kyle.

“He read the numbers over the radio for me and BAM! It was Christie. That’s when we sprang into action,” said Kyle.

And Christie looked good. The transmitter had clearly been knocked off—likely during mating.

But that is just the start.

Some of our team went down to Trinidad two weeks ago to train members of the Nature Seekers in safely attaching satellite transmitters to leatherbacks. We wanted them to put transmitters on Canadian turtles so we could get the first leatherback satellite tracks back to Canada from the nesting beach.

Kyle, Devin and Francis put one of those satellite transmitters on Christie.

Our goal is to watch her swim back home to us again.

When something like this happens it is hard to explain how slim the chances of it are. It’s miraculous. We are thrilled. And so proud of our friends at Matura. What a team!

No more Christie

2015_03_30_ChristieZoom

Christie’s tag stopped transmitting on Saturday.

We are so disappointed. She was just 300 kilometers away from where we expected her to nest. She had logged approximately 11,500 kilometres since we tagged her.

Data from the tag on March 28 showed that she was diving normally and that the tag had plenty of battery. But, as you may remember, Christie had just started onto the shelf waters, a place where we know leatherbacks mate. It is our best guess that a male turtle damaged the antenna of the transmitter or knocked the tag off her altogether.

There is also always a possibility that she was caught in fishing gear.

If indeed, as we hope, Christie simply lost the tag mating, then we will keep our fingers crossed that someone finds our turtle when she eventually hauls up on the nesting beach. She should still have her flipper tags safely in place as well as her microchip. And there is a chance that her transmitter is still on. If that’s the case, the transmitter can be recovered—along with all of the important data it contains—if someone finds her. This happened before in the amazing story of Red Rockette. So we remain cautiously optimistic.

But we will miss following her movements. Christie was a bright spot in our days as we checked always with excitement to see how far she’d travelled. What a privilege it was to watch her remarkable journey (11,500 kilometres!!) up close.

Close-up

This is what I mean about the leatherback beeline. This morning, Christie is only about 400 km from Fishing Pond beach, the place where she was seen nesting in 2011. She’s starting to head north along the shelf break to Trinidad.

Time for Trinidad

2015_03_26_full

Now we’re focused on Christie (although I do note that Beverly is moving more convincingly south). Christie is doing the amazing leatherback beeline. I love this part. After months of navigating the enormous ocean, she is heading directly for the waters off the Trinidad nesting beaches. Check out this close-up map.

2015_03_26_Christie2

Christie is covering a lot of distance quickly. She could be there within just a few weeks. We expect her to travel up and down the coast of Trinidad once she arrives in the vicinity—making us crazy wondering which night she’ll pick to haul ashore. Lots of excitement to come!

Plots thicken

2015_03_12

As I mentioned last week, I’m keeping my eye on Beverly right now. Still moving south. I think we’ll know in just a few more days whether or not she’s going to start the great swim toward Trinidad. I have the same feeling I get when I want to know the ending of a story right away without waiting any longer. And in this case, I can’t flip to the final pages of a book to satisfy my curiosity. Turtles teach me patience!

I’m glad to see Christie is heading closer to Trinidad.

It’s been one month since we last heard from Asha. And I have to admit wondering where she is, too. Asha was our mystery turtle this year. She didn’t have a recorded nesting history. No flipper tags. No microchip. Where she went was going to be a complete surprise. Hope we get to find out someday.
