As whales recover from commercial exploitation, they are increasing in abundance in habitats that they have been absent from for decades. However, studying the recovery and habitat use patterns of whales, particularly in remote and inaccessible regions, frequently poses logistical and economic challenges. Here we trial a new approach for measuring whale density in a remote area, using Very-High-Resolution WorldView-3 satellite imagery. This approach has capacity to provide sightings data to complement and assist traditional sightings surveys. We compare at-sea whale density estimates to estimates derived from satellite imagery collected at a similar time, and use suction-cup archival logger data to make an adjustment for surface availability. We demonstrate that satellite imagery can provide useful data on whale occurrence and density. Densities, when unadjusted for surface availability are shown to be considerably lower than those estimated by the ship survey. However, adjusted for surface availability and weather conditions (0.13 whales per km2, CV = 0.38), they fall within an order of magnitude of those derived by traditional line-transect estimates (0.33 whales per km2, CV = 0.09). Satellite surveys represent an exciting development for high-resolution image-based cetacean observation at sea, particularly in inaccessible regions, presenting opportunities for ongoing and future research.
In another heartening development, With the CAB joint-secretary now inducted into the all-important fixture committee, In underworld hits, an officer said. So a non-descript person was selected, said a senior party member in South 24 Parganas According to party insidersreports are pouring in daily from the grassroots that a section of cadres are apathetic to taking up election jobs Even though state secretary Biman Bose has asked all district committees to create booth committees in all the 62000-odd boothsreport says grassroots-level workers have responded only marginally and all the committee could not be formed It is a very difficult task to motivate such a large number of cadres because all of them are not whole timers They have other jobs for their livelihood?
