The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv,.esriCsv,.geoJson
attribute NC_GLOBAL acquisition_description String MODIS:

Dates of fast ice movement were determined from visible-wavelength scenes from
the MODIS\u00a0aboard the Aqua and Terra satellites.\u00a0 MODIS images are
available only for the months when there is sunlight, generally October to
April, and image resolution was 250 m.\u00a0 Figure A (see Supplemental
Documents) shows the division of McMurdo Sound into six zones; fast ice areas
were generated manually from clear-sky images by drawing polygons in GIS
software, and pack ice was excluded from analysis. The fast ice in MODIS
scenes was sometimes obscured by clouds, so for days with missing imagery we
interpolated linearly between valid data.\u00a0 Areas of persistent multiyear
ice or glaciers that were not considered in the analysis (white in the
figure).\u00a0 Linear distance between McMurdo Station and the nearest open
water on the day the ice reached the minimum extent for the season was also
measured.

SSMI:

In the SSM/I record, images were available for all months of the year, and
image resolution was 25 km.\u00a0 Figure B \u00a0(see Supplemental
Documents)\u00a0 shows the total of seven pixels in the 25 km polar
stereographic projection that encompassed McMurdo Sound; for each pixel, daily
or bi-daily fractional sea ice cover was extracted.\u00a0 SSM/I passive
microwave sea ice observations do not distinguish between fast ice and pack
ice. There are small amounts of land and ice shelf contamination in pixels 1,
2, 5 and 7.

attribute NC_GLOBAL instruments_2_dataset_instrument_nid String 743378
attribute NC_GLOBAL instruments_2_description String The Special Sensor Microwave Imager (SSM/I) is a passive microwave radiometer that measures atmospheric, oceanic and terrestrial microwave brightness temperatures at 19.35, 22.2, 37.0, and 85.5 GHz, from which ocean surface wind speed, atmospheric water vapour, cloud liquid water and rain rate can be derived. The SSM/I consists of an offset parabolic reflector of dimensions 24 x 26 inches, fed by a corrugated, broad-band, seven-port horn antenna. The reflector and feed are mounted on a drum that contains the radiometers, digital data subsystem, mechanical scanning subsystem, and power subsystem. The reflector-feed-drum assembly is rotated about the axis of the drum by a coaxially mounted bearing and power transfer assembly (BAPTA). All data, commands, timing and telemetry signals, and power pass through the BAPTA on slip ring connectors to the rotating assembly. The absolute brightness temperature of the scene incident upon the antenna is received and spatially filtered by the antenna to produce an effective input signal or antenna temperature at the input of the feed horn antenna. The SSM/I has seven channels, four frequencies, and is orthogonally polarised. It rotates continuously about an axis parallel to the local spacecraft at 31.6 rpm and measures the upwelling scene brightness temperature over an angular range of 102.4 degrees at nadir. The active scene measurements lie +51.2 to -51.2 degrees about the forward (F10, F11) or aft (F8) direction. This results in a swath width of approximately 1400 kilometres. During each 1.9 second scan, 128 discrete uniformly spaced radiometric samples are taken at the two 85 GHz channels and, on alternate scans, 64 discrete samples are taken at the remaining lower frequency channels. The antenna beam intersects the Earth's surface at an incidence angle of 53.1 degrees. Flown on F08, F10, F11, F13, F14, F15, F16, F17, F18 F19. https://nsidc.org/data/docs/daac/ssmi_instrument.gd.html

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, Adélie and Emperor penguins, and Antarctic toothfish. This project focuses on food web interactions of Adélie 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.
