Whales from Space: Counting Southern Right Whales by Satellite
We describe a method of identifying and counting whales using very high resolution satellite imagery through the example of southern right whales breeding in part of the Golfo Nuevo, Península Valdés in Argentina. Southern right whales have been extensively hunted over the last 300 years and although numbers have recovered from near extinction in the early 20(th) century, current populations ar...
متن کاملSouthern right whales wintering in the Auckland Islands

The North Pacific right whale was the subject of hunting in the gulf of Alaska from...
متن کاملConfirmation of right whales near a nineteenth-century whaling ground east of southern Greenland.
North Atlantic right whales (Eubalaena glacialis) were found in an important nineteenth century whaling area east of southern Greenland, from which they were once thought to have been extirpated. In 2007-2008, a 1-year passive acoustic survey was conducted at five sites in and near the 'Cape Farewell Ground', the former whaling ground. Over 2000 right whale calls were recorded at these sites, p...
متن کاملSightings of Dwarf (Kogia sima) and Pygmy (K. breviceps) Sperm Whales from the Main Hawaiian Islands
Sightings of dwarf (Kogia sima) and pygmy (K. breviceps) sperm whales in Hawaiian waters have only rarely been reported. As part of boat-based surveys of odontocete cetaceans around the main Hawaiian Islands between 2000 and 2003, Kogia were observed on 18 occasions. Kogia were sighted most frequently in deeper portions of the study area (mean depth, 1,425 m) and in calm sea conditions (mean Be...
