South Africa

Deploying site: 

  • Marion Island (Prince Edward Islands)

Supporting institutions: 

  • the South African National Antarctic Programme 
  • the Alfred Wegener Institute for Polar and Marine Research

Actors/People involved:



Deployments at Marion Island were done in collaboration with Germany. Two of those deployments (ct35x, ct73) are co-owned by both groups (presented  here). A further two deployments (ct54, ct102) were collaboratively done at King George Island. They are presented on the German page.


Presentation of the group: 

The southern elephant seal population on Marion Island (46°54’S; 37°45’E) has been extensively studied, particularly by means of a long-term mark-recapture investigation that has been in operation on the island since 1983. While previous studies have deployed some tracking devices on animals from this population, MEOP South Africa, through collaboration with MEOP Germany, aims to gain a better understanding of where seals travel to during their foraging migrations, their diving behaviour during these migrations, as well as the physical properties of water masses utilised by these top predators. Because most elephant seals stay at sea for close to ten months a year, the CTD-profiles obtained by seal-borne instrumentation will provide our oceanographers with virtually year-round data of water conditions in areas that are mostly difficult and expensive to reach by ship.
