For the first time ever we can now follow South Georgia whales in real time as they journey across their summer feeding grounds, to find out where they go and how they use this habitat. Two humpback whales were tagged on the 19th and 21st January 2019, and this map shows their locations. Overlayed on the map (when available) are the latest estimates of chlorophyll a density from the Global Imagery Browse Services (GIBS), operated by NASA/GSFC/ESDIS.
Click on a track to find out how far the whale has gone from the initial tagging location.
In the coming weeks we will find out where the humpback whales go in the austral autumn, and perhaps even watch them on their return migration to wintering grounds when they have finished feeding. This work will help us to better understand where whales feed in relation to areas of high primary productivity such as the Antarctic polar front, krill fishery hotspots, and the Marine Protected Areas of the region.
