**** Info via OCEARCH
OCEARCH is on the lookout for 5 pop-up satellite archival transmitting (PSAT) tags that were attached to white sharks in Atlantic Canada about one year ago. 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. Recovering any of these tags in hand would enable us to directly download all of the stored information – which would be a huge data windfall.
Of these 5 tags, 2 have detached and transmitted their locations, White shark Ulysses’ at the south end of Cape Sable Island and white shark Sarah’s from the outer part of St. Margaret’s Bay. The three other PSATs have not yet transmitted: white shark Scot, white shark Sable, and white shark Maple.
A PSAT tags is pictured below. They 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. If you find one of these PSAT tags please contact us at science@ocearch.org.
