  • Sad news

    We received some sad news yesterday. The Virginia Aquarium Stranding Response team responded to a leatherback that had washed up in False Cape State Park in southern Virginia. When they examined the turtle, they found a flipper tag. The tag was traced back to our program and when we looked up the number, we discovered that it was Anastasia. Anastasia was tagged by Rebeccah and I in 2009. She returned this past season and we saw her four times. She seemed to have had a rough life based on various injuries that we noted when we saw her. In 2009, she had a fresh scar around her right front flipper that appeared to have been caused by a line or rope that had become wrapped around her. This past season, we noticed that a good portion of her upper jaw was missing and on one encounter, we removed a small fishing hook from her shoulder. Sadly, when she was encountered in Virginia, she had 5 propeller marks from a very large boat. The stranding team was unable to determine if the boat strike had resulted in her death or had occurred after she died. She is a very sad example of the many threats that turtles face on a daily basis. Debris entanglement/ingestion, boat strikes, and fishing interactions are common causes of injury and death to thousands of turtles each year.

    Sadly, Anastasia is the fourth turtle that we’ve tagged that has been found dead. In 2002, Sandy, a turtle that was wearing a GPS transmitter, was found off the coast of New Jersey. Data from the transmitter indicate that she likely drowned in a scallop dredge. This northeast coast is an area of heavy commercial fishing. As our turtles pass through these waters after the nesting season, they must navigate through these busy fishing grounds. Daisy, a turtle we tagged in 2004, was found on Juno Beach in 2006. She had been hit by a boat. Nanelle was found just a month after we tagged her in 2009. She had also been hit by a boat. It’s terribly sad to hear stories of our tagged turtles that have died.

    On a positive note, we were able to track four of Anastasia’s nests through their hatch date. She laid a total of 254 eggs in those four nests and 183 of those produced hatchlings. On one of our encounters with Anastasia, we were able to snap a couple of photos. This photo was taken during a full moon. The long exposure allows us to take photos without using flash. I was watching Anastasia as she covered up her nest. One of our favorite things to do is just to sit with the turtles on pretty nights like this. Notice the large number of boats on the horizon. These boats were likely fishing for kingfish. They fish with the moon cycle and on a calm night, you can see hundreds of lights along the horizon. Pretty nights like these when we’re able to just enjoy being on the beach with the turtles remind us of why we do what we do.

  • They’re still here

    Our last official night was Friday, June 17th, but the leatherbacks didn’t get the message. We’ve had 23 nests on Juno and Jupiter beaches since we stopped night work. There have only been 3 days since then that we didn’t get at least one nest. It’s killing us that we can’t be out there looking for them. Fortunately and unfortunately we were needed on the day shift so we weren’t able to stay out there looking for our girls. It’s unfortunate that we don’t know who they are, but it’s fortunate because it means that this year’s nest count is so high that we had to switch over to help out.

    We are now on the day schedule and we’re out on the beaches each day looking for new nests. There are three species nesting on Juno and Jupiter beaches, with leatherbacks being the rarest. So far, on 7.5 miles of beach, we have recorded 249 leatherback nests, 354 green turtle nests, and 3,489 loggerhead nests! Every day we document 150 to 300 new crawls! This is quite an important beach.

  • A Few Numbers

    As we transition back to the day shift, I’ve been looking at the numbers from our 2011 season. We had a total of 352 encounters this year. That’s higher than we’ve ever had! We saw a total of 125 individuals, including 43 new girls. We saw Spica more than any other turtle. We had nine encounters with her (8 of these were nests and one was a false crawl). Elaine was also seen nesting eight times. Leigh and Clover each laid seven nests on our beaches. Also topping the list were Victoria, Tequila, Lacy, Katrina, Juno, Juliana, and Peach with six encounters each.

    We are still seeing a few leatherback nests on our beaches every day. As of yesterday, there were 196 on Juno Beach. That is the second highest total ever. I am also very happy to report that Clover’s first nest of the season hatched! 62 hatchlings successfully emerged.

    In addition to all of the leatherback work, we are documenting loggerhead and green turtle nests laid on our beaches. So far, we have 2,139 loggerhead nests on Juno Beach and 152 green turtles. It’s looking like a great year for the turtles!

  • End of season

    Well, we finally found Spica! She nested on the north end of Singer Island on Thursday night. I followed her GPS locations from the office and told Tommy and Jessica to keep a close eye out for her as they patrolled the south end. They found her at about 11:30 as she was just crawling up the beach. I’ve included a map of her final track below. In 14 days, she traveled 493 miles!

    We have now wrapped up night work for the season. The leatherbacks are still nesting but their season is coming to a quick end. There are so many loggerheads and green turtles nesting now that it is too difficult to get down the beach. I saw the last turtle of the season on Friday night as I watched June Bug emerge just south of the center. I sat with her the entire time and chatted with a very nice family from Chicago that was fortunate enough to meet June Bug. We will attempt to use genetics to identify the late season turtles that we miss. We will continue to update as we work through the season. We are looking at a very busy loggerhead and green turtle year so we should have some exciting nesting updates as we continue.

  • Still no Spica!

    Well Spica is really messing with us now. We’ve been tracking her for almost 14 days. Leatherbacks typically nest every 9-10 days but we see occasional long intervals like this one. She’s keeping us on our toes by cruising up to the beach every night. I’ve included maps of Spica over the past few days and Andromeda from her tracking period. Note the difference between the two. Andromeda came straight back and spent very little time along the coast before nest. Spica has looped all over the place. We saw this behavior in a couple of our tracked turtles from last year too. Very interesting. We’ll be back out there looking for her tonight!

    We’ve seen eight leatherbacks in the past two nights so they’re definitely still here. Last night was Jacob’s last night with us and he found Erin (a 2001 turtle) and Tierra (a 2007 turtle). We wish Jacob well as he ventures out to do some turtle work in St. Croix and then off to grad school. Andrew found Dee as well as one of our new turtles from this year. We are hoping Clover makes one more appearance before the season is over!

  • Where is Spica?

    We’re still waiting for Spica to return! It has been thirteen days since she got her second transmitter so we’re definitely expecting her soon. She’s been really teasing us for the past few nights. She has stayed very close to the coast in Martin and northern Palm Beach County so each night we go out expecting her to nest but she continues to wait. I’ve included a map to show you the winding track she’s made as she’s cruises along the coastline. She’s not making it easy on us but we’re hoping that tonight is the night!

  • Corrected link

    I corrected the link to the story about Clover. In the post below, click “Check it out here” to read the story. It’s been slow lately. There were no leatherbacks last night and so far we’ve seen just one tonight. Jacob just found Rainy down in MacArthur Park. It’s a nice night for a drive though. The moon is very bright and the tide is out. I’m heading out to find some more of our girls.

  • Clover in the news!

    I am very happy to report that CNN picked up the wonderful video that Chris put together of our girl Clover. The story was published today. Check it out here

    Chris and I are currently on Jupiter Island tracking down Spica. Her VHF transmitter is telling us that she’s directly in front of us heading south. We’re thinking she’ll be back on Juno Beach tomorrow night.

  • Three more last night

    The numbers have slowed but the turtles are definitely not done. Salena, Polaris, and Kalindi nested last night. Kalindi is one of our 2003 turtles. She nested in 2003, 2004, 2006, 2007, and this year. Our bets are that we’ll see her again next year because it seems she tends to nest in consecutive years. Last night we saw Corey, Frenchy, and Josie. The surf is pretty big right now and the amount of loggerheads that we’re seeing each night are leading us to decide to wrap up our season pretty soon. We are very, very careful to stop and wait for any loggerheads that are emerging and it makes for a very long trip down the beach when we see dozens of loggerheads each night. We’ll put a few more days in before we say goodbye. We’re getting ready for Spica to return over the weekend. We will recover her transmitter, the final one of the year. She is currently just south of the St. Lucie Inlet and we expect her here on Juno tomorrow or Sunday night.

    We now have 466 turtles in our database! That’s a lot of turtles over the past 11 seasons. Those turtles make up a total of 1,838 encounters! Of course, Juno holds the record with 27 encounters in ten years. Clover and Spica are a close second with 22 encounters each and Ursa wraps up the 20s with 21 encounters. Not too surprising that they make up our top four as they were each tagged within the first three years of the project. Interestingly, one of our turtles with the sixth most encounters was just tagged in 2007. Leigh has been here 15 times over three seasons. It’s always fun to look at the great history we’re building with some of these turtles.

  • The season winds down

    We’ve got just a week or so left of night work and we are staying busy. So busy that I haven’t even had time to blog. Whew! We are seeing three to four turtles a night currently. Towards the end of the season, we get an interesting mix of turtles. Often, we see turtles that we haven’t seen yet during the season. We’re likely seeing a northward shift as the turtles prepare to head north for the summer. Remember – our girls head to Canada to feed after nesting wraps up at the end of June.

    Last night we saw Veronica. We haven’t seen Veronica yet this year but she did nest last year. She is the fourth turtle this year that also nested last year. We also saw Lacy lay her sixth nest on Juno Beach for the year. We’ve got several turtles that we’ve seen lay seven nests, including Spica, Leigh, Clover, and Elaine. The nesting season is thundering along! We’ve now recorded over 1,700 loggerhead nests on Juno and Jupiter beaches alone (7.5 miles)! In addition to loggerheads, we’ve got 210 leatherback nests and 39 green turtle nests! Those numbers are looking pretty good!

    For those of you that got to check out the Clover video a few posts back, you’ll be happy to know that she nested again three nights ago! With a little help from Jacob this time, we were able to once again help Clover successfully lay eggs. Each of us that has had the opportunity to dig for Clover feels pretty attached to her and we are so happy to see our girl doing well this year. I really hope that she comes back for just one more nest before the season is over!

    And last but not least – this morning, Liz, Rachel, Caroline, and I got to watch several of Lacy’s hatchlings make their way to the ocean. Lacy has nested 6 times on our beaches, including last night, the same night that her first nest of the season hatched! If you’ve never seen leatherback hatchlings before, they’re pretty cute! They are about 3 inches long and look very similar to the adults. Their extremely long front flippers help propel them through the water.
