Data on the species encountered (including marine mammals), their abundance, distribution and behavior. Data collected aboard cruises off the coast of the Western Antarctic Penninsula, 1993, 1999 and 2001. | The objectives of the LTER seabird component during the 92-93 season cruises were similar. These objectives included 1) determining the pelagic abundance and distribution of Adelie Penguins, 2) examining how the physical and biological characteristics of the marine environment influence these parameters and, 3) using these data to identify foraging areas that may be important to Adelie populations being studied as part of land-based work at Palmer Station. Secondary objectives included documenting the abundance and distribution of other seabirds and marine mammals within the LTER study area. The focus of the January cruise was the nearshore foraging habitat,which required sampling at smaller scales. All seabird censuses were thus conducted within approximately 100 kms of Palmer Station while traversing a sampling grid with stations at 10km intervals. The first two days (18-20 January) of this cruise were spent covering the selected grid as rapidly as possible resulting in 45 transects spaced at 45-60 minute intervals. There were no stops at the 10km stations during this Fast Grid phase. Upon completion of the Fast Grid, a force 12 gale suspended data collection for 24 hours. From January 22-25 the grid direction was reversed and the grid repeated. During this Slow Grid phase, 2-M net tows were done at 10km intervals and BOPS and 1-M and 2-M net tows every 20 km. All seabird censusesduring the cruise were done using the procedures outlined in theprevious paragraph.\n\ncdm_data_type = Trajectory\nVARIABLES:\nevent\ncruise_id\nstudy_name (Study)\ndepth (m)\nlatitude (degrees_north)\nlongitude (degrees_east)\ntime (seconds since 1970-01-01T00:00:00Z)\nstation\ngrid_line (km)\ngrid_station (km)\nsea_state\nsalinity (Sea Water Practical Salinity, 1)\n...

All seabird censuses during the cruise were done using the procedures outlined in the previous paragraph.\\n\\nSeventy-two 30-minute transects and 15 station censuses were completed during the January cruise. Athough seabirds were widely distributed throughout the study area, the highest densities and greatest biomass occurred consistently within 2-5 km of Anvers Island and several major island groups to the south and \\nwest near the Antarctic Peninsula. Adelie Penguins were the dominant component of this seabird assemblage in terms of both abundance and biomass. South Polar Skuas ranked second and Black-browed Albatross third, with the latter becoming the dominant assemblage member at distances greater than 10km from land. Although \\nSouth Polar Skuas had been expected to occur in more pelagic habitats, few were censused at distances greater than 10km from land. The presence of both skuas and penguins so close to land was unexpected. The most important variable accounting for variation in the distribution and abundance of seabirds appeared to \\nbe the location of the 200m contour, which throughout the study area occurred 2-5km from the adjoining land masses. Approximately 65% of the seabirds censused during this cruise (85% of the biomass) occurred in association with this contour.\n\ncdm_data_type = Trajectory\nVARIABLES:\nstudy_name (Study)\n...

Salps (Salpa thompsoni) are conspicuous gelatinous zooplankton capable of rapid population increases, enabling them to respond quickly to unpredictable phytoplankton blooms common in the Antarctic. Body length was measured on salps collected from LTER zooplankton tows along the western Antarctic Peninsula. Salps have amongst the highest filtration rates of all zooplankton, and package their waste into large, fast sinking fecal pellets. These pellets provide a mechanism to export carbon fixed in the surface waters into the deep ocean. Since filtration rates and pellet size are positively related to the size of a salp, population estimates of grazing and exported carbon can be determined through length data.\\n\n\ncdm_data_type = Trajectory\nVARIABLES:\ncruise_tow_number\ncruise_name\nevent\ntow_number\ngrid_line\ngrid_station\ntime (Start Time, seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\nend_time (seconds since 1970-01-01T00:00:00Z)\nlat_end (Latitude, degrees_north)\nlon_end (Longitude, degrees_east)\ntow_duration (minutes)\nheading (degrees)\nspeed_over_ground\ndepth (m)\nwind_speed (m s-1)\nwind_direction (Wind To Direction, degrees)\n...

Antarctic krill, Euphausia superba, are a critical food-web link between phytoplankton primary production and higher trophic levels, such as whales, penguins, and seals. Krill standard length was measured from LTER zooplankton tows along the western Antarctic Peninsula. Length data provides estimates of age-class abundance and recruitment. Climate-induced changes in krill recruitment are an important consideration in the management and modelling of krill populations.\\n\n\ncdm_data_type = Trajectory\nVARIABLES:\ncruise_tow_number\ncruise_name\nevent\ntow_number\ngrid_line\ngrid_station\ntime (Start Time, seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\nend_time (seconds since 1970-01-01T00:00:00Z)\nlat_end (Latitude, degrees_north)\nlon_end (Longitude, degrees_east)\ntow_duration (minutes)\nheading (degrees)\nspeed_over_ground\ndepth (m)\nwind_speed (m s-1)\nwind_direction (Wind To Direction, degrees)\nnet_id\ntow_type\n...

Many zooplankton feed on phytoplankton in surface waters and thus provide a link between primary producers and higher trophic levels. Other zooplankton reside in the mesopelagic zone and feed on detritus or on other animals. Depth-discrete density of zooplankton taxa was determined at process study stations on the annual Palmer LTER cruises along the western Antarctic Peninsula. Samples were collected with a 1.4-m2 frame, 500-μm mesh Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS) towed obliquely to the surface from a depth of typically 500 m. MOCNESS tows were conducted in consecutive day-night pairs at each process study station. Zooplankton depth distributions vary between day and night as these animals conduct diel vertical migrations. Depth distributions also vary among zooplankton taxa based on species feeding ecology and life history traits. Zooplankton diel vertical migration contributes to the export of carbon and nutrients from the surface ocean to the mesopelagic zone.\n\ncdm_data_type = Trajectory\nVARIABLES:\ntow_start_datetime (MOCNESS start datetime, seconds since 1970-01-01T00:00:00Z)\ntow_end_datetime (MOCNESS end datetime, seconds since 1970-01-01T00:00:00Z)\nlatitude (Net Lat Avg, degrees_north)\nlongitude (Net Lon Avg, degrees_east)\ncruise_name\ngrid_line\ngrid_station\namphipoda\ncacutus\nchaetognatha\ncpropinquus\necrystal\ngymnosomata\nlhelicina\nmgerlachei\nostracoda\n...
