A technology partnership between H.A.B.I.T. Research Ltd. and u-blox will soon make it possible for scientists to study the behavior of endangered species once thought too tiny to be tracked by GPS, raising the hope that many smaller species may be saved from extinction, according to H.A.B.I.T. President Jeffrey Goodyear.
A tracking tag mounted atop a seal's head rapidly sheds water when the animal surfaces so the GPS antenna has maximum exposure to the sky. The tag's sensors and electronics are potted to protect them from salt water and to withstand up to 3,000 psi pressure.

The observation technology used by wildlife researchers can limit their understanding of the behavior of marine mammals. Surface tracking using geolocation and Service Argos tags have shown that these mammals range much farther than previously thought. Relatively simple time/depth recorders (TDRs) show that they dive more than 1,000 meters deep and for longer than one hour. To further the understanding of these aquatic creatures, we developed a smaller and more capable tag with more sensing capabilities that can be deployed for longer durations. The MAMMARK tag, measuring 2.5 ? 4 centimeters, carries a low-power microprocessor and a set of sensors that can be multiplexed through a high-resolution analog-to-digital converter (ADC).
