Cetaceans Sightings During Research Cruises in Three Remote Atlantic British Overseas Territories
Marine mammal sightings were recorded during research cruises to three remote, mid-ocean British Overseas Territories in the South Atlantic and Southern Ocean. In March to April 2018 and 2019, the Exclusive Economic Zones (EEZs) of tropical St Helena and temperate Tristan da Cunha were surveyed. The...

In 2019, due to rough weather, no sightings were recorded in the Tristan da Cunha waters.
