Dataset: Seabird and marine mammal sightings
Deployment: LMG1504

Methodologies are those described in Force et al., 2015. 

Visual survey effort for seabirds, marine mammals and environmental conditions (e.g., sea state, sea ice conditions) was conducted continuously during daylight hours when the ship was in transit.  An observer worked inside the bridge (starboard side) of the R/V Laurence M. Gould and recorded all sightings onto a computer synced to the ships’ data acquisition system. Survey effort covered the Patagonia shelf, central Drake Passage (north and south of the Polar Front), coastal Bransfield Strait, Gerlache Strait, Neumeyer Channel, and northern waters around King George Island and Elephant Island.  Moreover, visual survey effort was conducted during all fishing and CTD operations coinciding with other projects during all three cruises.
