Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv,.esriCsv,.geoJson,.odvTxt
attribute NC_GLOBAL acquisition_description String A small hole was drilled in the McMurdo Sound fast ice. The CTD was deployed
below the fast ice to ~ 2 m depth. The CTD was then powered on and allowed to
sit a few minutes until the pumps turned on and sensors stabilized and
equilibrated. The CTD was then lowered using a hand winch to depths between 97
and 175 m.

attribute NC_GLOBAL project String Food web dynamics in an intact ecosystem: the role of top predators in McMurdo Sound
attribute NC_GLOBAL projects_0_acronym String McMurdo Predator Prey
attribute NC_GLOBAL projects_0_description String Extracted from the NSF award abstract:
The research project investigates the importance of top down forcing on pelagic food webs. The relatively pristine Ross Sea includes large populations of upper-level predators such as minke and killer whales, Ad�lie and Emperor penguins, and Antarctic toothfish. This project focuses on food web interactions of Ad�lie penguins, minke whales, and the fish-eating Ross Sea killer whales, all of which exert foraging pressure on their main prey, crystal krill (Euphausia cyrstallorophias) and silver fish (Pleuragramma antarcticum) in McMurdo Sound.
The investigators used a video- and acoustic-capable ROV, and standard biological and environmental sensors to quantify the abundance and distribution of phytoplankton, sea ice biota, prey, and relevant habitat data.� The sampling area included 37 stations across an 30 x 15 km section of McMurdo Sound, stratified by distance from the ice edge as a proxy for air-breathing predator access. This study will be among the first to assess top-down forcing in the Ross Sea ecosystem and will form the basis for�multidisciplinary studies in the future.
