Sea Turtle Ecology and Population Dynamics Research at NEFSC
Since 2009, a group of collaborators have deployed > 150 satellite tags on loggerheads within the U.S. Mid-Atlantic Bight of the Northwest Atlantic Ocean. These tags collect and transmit location, temperature and depth information and have yielded 18,790 temperature-depth profiles during the highly stratified season (01 June -04 October) for the region. This includes 16,371 profiles exceeding the mixed-layer depth, and, of those, 11,591 full water column profiles reaching the ocean floor. The use of turtle-borne telemetry devices has the potential to improve oceanographic model outputs.The following paper describes the oceanographic data associated with satellite tags placed on loggerhead sea turtles:
Loggerhead turtles are good ocean-observers in stratified mid-latitude regions.
Data from this paper are available here.
END_DATE = Time of the end of the dive in UTC
LAT / LON = Approximate positions for end of dive
N_TEMP = The number of (pressure,temperature) pairs
TEMP_DBAR = A comma-separated list of the pressure coordinates of the (pressure,temperature) profile (decibars)
TEMP_VALS = A comma-separated list of the temperature coordinates of the (pressure,temperature) profile (°C)
