15.02.2019 Animal tracking applications Argos celebrates World Whale Day

Whales are some of the most fascinating creatures on Earth. They inhabit all of the world’s major oceans, including the Arctic, the Antarctic and the tropical waters of the Atlantic, Pacific and Indian oceans. From the blue whale, which is the world’s largest, to the elegant narwhal, these enigmatic marine mammals attest…

15.02.2019 Animal tracking applications Understanding the impact of human activity on narwhals in the Arctic

Wide-scale changes are taking place in the Arctic, with warmer temperatures leading to shrinking summer ice coverage.  More ice-free water means easier access for vessels and industrial operations, such as exploration for oil and gas, shipping, sand dredging and fisheries. Faced with these changes, how can we protect vulnerable Arctic marine…

15.02.2019 marine animals Shedding new light on South American penguins home range

Humboldt and Magellanic penguins live in the southern tip of South America. On the Pacific coast, they benefit from the high productivity of the Humboldt Current but are also threatened by artisanal fisheries. They are thus considered as either vulnerable or near threatened, and conservation measures should be taken. Their…

23.11.2018 Animal tracking applications Argos helps to define a protected area for elephants in Cameroon

African elephants are under assault due primarily to the illicit ivory trade and, to a lesser extent, to habitat destruction and human incursions. Numbers are plummeting throughout most range states. Understanding elephant movement patterns, home ranges, land use patterns and corridor use are essential in developing conservation strategies.

20.11.2018 Flash news Argos-3 instrument successfully activated on EUMETSAT’s Metop-C satellite
