Marine Mammals and Seabirds and Turtles: Summer search effort of Western English Channel Marinelife Surveys
Marinelife at-sea survey effort for megavertebrates in the Western English Channel. Surveys recorded sightings of large pelagic fishes and sharks, cetaceans, seals and sea turtles. The data span from 2007 - 2011 and come from both dedicated and opportunistic surveys in the CHARM3 study area. Survey effort should be viewed with relative-abundance layers of the various megavertebrate groups.

- Explanation
-
At-sea survey effort for megavertebrates (large pelagic fishes, sharks, marine mammals, sea turtles) in the Western English Channel . The data were provided by Marinelife from a dedicated and opportunistic surveys on a variety of platforms over 5 years. Search effort should be viewed with sighting relative abundance layers.
- Pass
- Statement
-
Sightings records were contributed by: Marinelife. Data were filtered to remove obvious location errors (i.e. on land), in poor seastates (>3 Beaufort Scale), from high-speed (ferries), static (dive)vessels, or when chumming occured (fishing). The filtered dataset was then used to generate survey effort rasters in 0.25 degree resolution.
