Cetacean Transdermal

Transdermal cetacean tags are deployed either using a pneumatic air gun or a long fiberglass pole. The tag electronics are cast in epoxy then encased in a stainless steel housing for robustness. Etched rings on the housings provide a visual means to measure the amount of tag migration out of the whale. A “stop plate” at the distal end of the tag limits the depth of the implant. A variety of different stop plate styles are available.

Life calculations assume a nominal 250 Argos transmissions per day. It is important to note that when tagging cetaceans, deployment length is typically limited by tag retention rather than battery capacity.
