North Atlantic – Abundance Estimates of Relevance to NAMMCO // All Cetacean Species – All Surveys (All estimates & Best estimates)
An overview will be available soon.
To effectively manage the impacts humans have on marine mammals, we need to know how many animals are in the management area (abundance), and how this number varies over time (trends in abundance), i.e. is the population going up, down, stable? One way to get this information is to carry out sightings surveys to count or estimate the abundance of whales or seals in specific areas. Surveys for seals and whales can be carried out from planes and boats or from land, using different methodologies.
The video below is an animation created by the Greenland Institute for Natural Resources to illustrate the method the scientists use to estimate the abundance of cetaceans off Greenland.
