When diving animals help us to observe the oceans

Over 800,000 vertical profiles of Temperature and Salinity have been collected since 2004 in the World Ocean by attaching tags on marine mammals, such as Southern elephant seals.

In this website, you will find information about the marine mammal tagging programs, and an access point to the publicly available databases.

Another short note gives an overview of the current state of ocean observations using tagged animals: Ocean Observations Using Tagged Animals by Roquet et al.

These papers are part of the Special Issue on Autonomous and Lagrangian Platforms and Sensors (ALPS) in Oceanography, following the meeting ALPS ( that took place in San Diego last February and was aimed at developing a broad vision for ALPS technology, capabilities, infrastructure, and user base in the next decade, and in the coming decades.

Note that this special issue also include the following papers on new exciting technologies of great potential for bio-logging:

      Do Southern Elephant Seals Behave Like Weather Buoys? by Cazau et al.

      A New Technology for Continuous Long-Range Tracking of Fish  by Rossby et al.
