White Sided Dolphin


Satellite Tagging
Observation Reports

White-sided Dolphin (Lagenorhynchus acutus) was tagged and released by researchers with the New England Aquarium and the Cape Cod Stranding Network. The team managed to get a satellite tag out on a rescued and beach-released white-sided dolphin. It is one of three that were released together on Tuesday (2/15/05) at Herring Cove Beach in Provincetown. Four others died. The tagged animal is a sub-adult male, about 206 cm long.

On 15 Feb 2005 the New England Aquarium, the Cape Cod Stranding Network, and the International Fund for Animal Welfare responded to a mass stranding of Atlantic White-sided dolphins in the area around Wellfleet, Ma. There were 8 animals total; 4 were found dead, and 4 were alive. Three animals were healthy enough to be relocated out of harm's way and one was euthanized due to its poor condition. The 3 healthy animals were transported by truck to Herring Cove Beach in Provincetown, MA where an ARGOS linked satellite tag was affixed to the largest animal's dorsal fin (a sub-adult male) before they were released together.

The tag was provided through the John H. Prescott Marine Mammal Rescue Assistance Grant Program to study the fate of re-located and released mass stranded animals. The grant provides funding for tags for up to 12 animals, as well as for advanced diagnostic tools to triage animals in the field. We see this as a great opportunity to follow cetaceans after stranding events, which we hope will reveal interesting and helpful insights into the dolphins' ability to recover from the trauma of coming ashore.
