Are we overestimating sea turtle populations?

A new paper out last month presents the possibility that typical sea turtle population assessment methods via foot patrols may be overestimating nesting populations by as much as a factor of 2. You can view it here.

The paper uses satellite tracking of nesting green turtles (Chelonia mydas) at their study site to show that they lay an average of […]

Tracking offshore migrations

Satellite tracking data is coming in for the 3 hawksbill sea turtles that received Platform Terminal Transmitters just over a month ago on Long Island, Antigua. The transmitters have 2 “saltwater switches” that, when exposed to air as the turtle surfaces to breathe, trigger the transmission of its location and stored sensor data (temperature, depth). So far we have been tracking […]

Hawksbill Hatchling Season in Antigua

DSCN0339

Shortly after 2am on July 24th, the Jumby Bay Hawksbill Project in Antigua observed our first hawksbill sea turtle hatchlings of the season! Hawksbills typically lay around 150 eggs that will incubate in their sandy chambers for 50-60 days. After hatching, the turtles will rest for one to two days while […]

Satellite tracking sea turtles

This month we are planning to deploy 3 satellite tracking devices onto 3 hawksbill females. These are known as Platform Terminal Transmitters (PTTs). They provide information on the offshore movements of sea turtles that are otherwise near impossible to study. Roughly 10 years ago, the Jumby Bay Hawksbill Project(JBHP) deployed 3 PTTs, so it will be interesting to revisit the research in […]

One month into hawksbill nesting season

The start of July was the one month mark of our hawksbill monitoring season in Antigua. While over 29 years of monitoring (1987-2015) there has been a significant long-term increase in nesting numbers, June 2016 had a puzzlingly low amount of activity relative to previous Junes. We had 15 fewer nests than in June 2015 (24 vs. 39), as well as 8 […]

Highlights from the 2016 International Sea Turtle Symposium

The 2016 International Sea Turtle Symposium (ISTS) recently took place in Lima, Peru. I attended and presented a poster on the issue of sargassum accumulation on our nesting beach in Antigua and the rest of the eastern Caribbean. We have touched on this issue in previous posts, including a natural history note that came out in September.

ISTS Lima proved to be an […]

Marine Megafauna Enjoying Abaco’s Non-developed Shorelines

By Stephanie Wenclawski

Here is an update on our drone project looking at how human activities may affect the distribution of marine megafauna such as sea turtles, sharks, and rays (see here and here for previous posts). So far, we have seen more marine wildlife in non-developed areas with just minutes of aerial footage.  For more detail on our latest data, please read more below and enjoy this short clip of a couple of clips from two of our surveys.  […]

Sargassum accumulation may spell trouble for nesting sea turtles

Andy is well ahead of the game – a first-authored paper before even enrolling at NCSU.   An easy paper to follow – read it all.

Hatchling season is in full swing

An update from Antigua and new NCSU graduate student Andrew Maurer.  Thanks Andrew!

Hatchling season is upon us on Long Island, Antigua. Nests that we saw deposited 50-60 days ago are hatching, often multiple in a night. It usually happens so fast we only see the tracks they leave behind. Seeing tiny hawksbill hatchlings leaves no doubt about it, this is […]

Sargassum and nesting turtles

A quick update from new NCSU graduate student Andrew Maurer on the sargassum mats in the Eastern Caribbean.  Thanks Andrew.

“Huge influxes of sargassum seaweed on coasts and nearshore waters throughout the Caribbean are drawing more and more attention from all sectors, especially conservation organizations. There are benefits to beaches such as stabilization and vast nutrient provision. Oceanic sargassum is also […]
