Seabird assemblages observed during the BROKE-West survey of the Antarctic coastline (30-80 E), January-March 2006
Progress Code: completed Statement: Observations of the numbers and behaviours of all seabirds present within a 300m forward quadrant of the ship were recorded continuously while the vessel was underway during daylight hours. Ship-followers were excluded from all analyses following BIOMASS Working P...
