Brief description
Acoustic telemetry data for juvenile hammerhead sharks were collected at Golfo Dulce, Costa Rica, to better understand patterns of residency of 1 year old sharks in the estuary. The area is known for presenting high abundance of neonates and juvenile hammerhead sharks, but previous data included only fisheries dependent surveys, with little information on the habitat use and residency patterns of these sharks. Telemetry data collected have been crucial for proving the presence and high residency of juvenile sharks and led to the designation of Golfo Dulce as a protected shark sanctuary and nursery site. Sharks were tagged with internal passive acoustic VEMCO tags on June 2, 2011 and data on their movement patterns collected on a receiver array in shallow waters of Golfo Dulce until February 2013.\nNotes

Sharks were captured by rod and reel using sardines as bait, and tagged using coded transmitters V13 and V16 from Vemco Ltd., Halifax, Nova Scotia, Canada. Transmitters had a battery life of 3 years and emitted a pulse train of closely spaced 69 kHz pinged. A receiver array of three VR2 receivers was deployed prior to tagging in a 15-18m muddy bottom close to a wetland ecosystem. Receivers stored information on detections along a 350-500 radius.\nModified: 20200430
