Polar seals are used to collect in situ measurements of temperature, salinity, fluorescence and light along their paths during their dives and which complement and extend to deep depth satellite surface observations. Information on sea states, direction and wind strength are also sampled. Simultaneously, biological data on nekton and prey density are also collected using a combination of methods such as assessing prey catch attempts from acceleration and passive acoustic measurements, measuring bioluminescence distribution and active echo-sounding. By combining these data we aim at assessing study how oceanographic conditions influence the vertical and horizontal distribution of biological fields on a fine spatial scale. Today, southern seals represent a major component of the Southern Ocean observing system and help us to evaluate how quickly that system is changing.
