Seals from Space: Developing techniques to use satellite remote sensing to census pack-ice seals in the Prydz Bay region of East Antarctica
Despite being a ubiquitous and abundant component of the Southern Ocean ecosystem, pack-ice seals (crabeater, Ross and leopard seals) are notoriously difficult to census as they are sparsely distributed over large regions of remote pack-ice. Historically, population censuses have been made from ship...
