OCEARCH seeking help locating shark tags

By Evan Taylor Sep 22, 2022 | 12:08 PM

The marine biology research group OCEARCH are asking for help in locating some pop-up satellite archival tag (PSAT), which are used to track marine species’ movements across the ocean.

Last year, OCEARCH attached five of these tags to white sharks around the Atlantic region with the goal of collecting the PSAT’s and analyzing their data.

The tags were programmed to detach from the shark after 365 days and transmit summaries of the light, depth, and temperature data they’ve stored while attached.

The tags look like a small lightbulb that can fit in the palm of your hand and have an antenna sticking out from the top. Their color can be grey to black – depending how much of the black antifouling paint has worn off.

Two of the tags recently detached and transmitted their location, one near St. Margarets Bay and the other near Cape Sable Island.

OCEARCH is now seeking help in locating them.

The one near St. Margarets Bay belonged to a white shark named Sarah, it last pinged on September 14, near Hacketts Cove. Some weak non-locational transmissions were received on 16 Sept but it has no signals have been received since then.

The other tag was attached to a white shark named Ulysses, and last pinged on September 11, near the South end of Cape Sable Island. Some of the tag’s pings were on land leading OCEARCH to believe it may have washed up ashore.

In addition to the two tags that have detached another three attached to white sharks named; Sable, Maple and Scot are expected to detach shortly and ping their location at which point OCEARCH will release more information they hope will aid in their recovery.

Should you find one of the tags, it asked that you email OCEARCH to coordinate a pick-up.
