The first large-scale epidemiological health assessment of turtles in WA, this project will determine disease prevalence, health risk factors, causes of mortality, and factors influencing hatching success in three sea turtle species.

A total of 264 unique turtle shells were observed in the dataset, based on the unique turtle IDs. Dataset Overview: This dataset contain information about various turtle sightings, with each entry detailing the image file and associated metadata for each turtle sighting. The dataset includes the following fields: index: An identifier for each row or entry in the dataset (appears to be auto-generated). photoname: The filename of the photo taken of the turtle, including the date and description of the image (e.g., carapace photos). turtle_ID: A unique identifier for each turtle, possibly denoting a tag or observation number. year: The year when the photo was taken. month: The month when the photo was taken. day: The day when the photo was taken. Summary of Data: The dataset provides a chronological record of turtles identified through their respective photos. The filenames in the photoname column indicate the type of image (e.g., carapace), and the corresponding turtle ID and date are embedded within the filename. The dataset spans multiple years (e.g., 2019, 2020, 2023), providing longitudinal information about turtle sightings or tracking.

This data set contains sea turtle length and weight measurements, sex ratios, species composition, capture and release locations, tagging information, and information on biological samples collected for loggerhead, green, and Kemp's Ridley sea turtle populations in the coastal waters of North Carolina. Sea turtles were double-tagged with Inconel Style 681 tags (National Band and Tag Company, Newport, Kentucky, USA) applied to the trailing edge of each rear flipper. Beginning in 1995, all turtles were additionally tagged with 125 kHz unencrypted Passive Integrated Transponder (PIT) tags (Destron-Fearing Corp., South St. Paul, Minnesota, USA), injected subcutaneously above the second-most proximal scale of the trailing margin of the left front flipper to ensure identification of the turtle in the event that both Inconel tags were lost. SCL and CCL (notch-to-tip and notch-to-notch) along with SCW and CCW were measured and recorded to the nearest 0.1 cm. Blood samples were collected from the dorsal cervical sinus of the turtle, and skin samples were collected from the trailing edge of the rear flippers. Scute scrapings were collected from the edge of the carapace

Studies are being conducted for transect surveys and mark-recapture to assess long term relative abundance

This data contains sea turtle life history, diet analysis, and environmental data, recorded as CSV spreadsheets ranging from 1997 to 2003. This data was used to determine relative abundance, temporal and spatial distributions, movements, habitat requirements, feeding habits, and sex ratios of immature sea turtles in the nearshore waters of West Florida. Research efforts focus on the highly endangered Kemps Ridley turtle, but other turtle species were opportunistically collected during routine sampling operations.

Data on the Turtle Nest Survey at 40 Mile Beach

We used passive acoustic telemetry to examine the effects of a jetty and artificial light on the rates of predation of flatback turtle (Natator depressus) hatchlings as they disperse through nearshore waters. A total of 61 hatchlings were released, 30 of which were released when artificial lights were present on the jetty. Predation rates were high, irrespective of the presence or absence of artificial light. Around 72% of the tagged hatchlings were predated before they could transit the nearshore. Evidence for predation was provided by tag detachment, likely due to prey handling by a predator or the extensive movement of the tags within the receiver array suggesting that the tag (and hatchling) was inside the stomach of a predator. This allowed us to track the movement of the hatchling predators. We found that 70% of the fish predators that consumed tags used the jetty as a refuge during the day and moved along nearshore waters at night. Our study shows how industrial development and the creation of nearshore structures such as jetties may have unintended consequences and pose a significant threat to populations of vulnerable species.

These data contain acceleration, pitch, yaw, roll, and ancillary data collected by acceleration data loggers (ADL) attached to four sea turtle species: green (Chelonia mydas) sea turtles, hawksbill (Eretmochelys imbricata) sea turtles, Kemp's ridley (Lepidochelys kempii) sea turtles, and loggerhead (Caretta caretta) sea turtles. A total of 54 nesting events and 76 non-nesting emergence events were identified in the data and validated by satellite tag location data for three of the four species (i.e., Kemp's ridley spatial data not included) and researcher observations.
