Sea Turtles in the Peconic Estuary

With a total of 15 cold-stunned sea turtles tagged, NYMRC was able to track and monitor sea turtle movements throughout New York and beyond.

Background

  • Kemp’s ridley (Lepidochelys kempii)
  • Green sea turtle (Chelonia mydas)
  • Loggerhead sea turtle (Caretta caretta)
  • Leatherback sea turtle (Dermochelys coriacea)

Tracking Post-Release Movement Patterns

Turtles that were rescued, rehabilitated, and released were tracked with support from PEP. Computers satellite tags enabling monitoring of post-release movement behavior on green sea turtles. Satellite tags provide long-duration (year+) intermittent information on the geographic position, dive profile, and sea water temperature of the animals.

Significance of the tagging

The presence of eelgrass beds and other submerged aquatic vegetation (SAV) were shown to be an important forage resource for juvenile green turtles. 

This plays a key role in retaining individuals within these nearshore habitats post-release.  These findings highlight the ecological importance of coastal estuarine systems to the life history of green sea turtles, emphasizing that New York waters are not merely ‘transitional zones’ but are functionally significant developmental habitats.
