EUMETSAT's product classifies global sea ice into open water, open ice, and closed ice categories. The sea ice edge is derived for both hemispheres using a Bayesian approach to combine passive and active microwave sensor data. The dataset was last updated in April 2018.
The Ross Sea Marine Protected Area is the location for this sample collection of zooplankton and phytoplankton. The dataset likely contains characteristic study data for plankton in the marine ecosystem, contributed by the organization AMD_KOPRI and last updated in March 2018.
Quantitative analysis of zooplankton community structure in the Ross Sea Marine Protected Area. The dataset was contributed by the organization AMD_KOPRI and last updated on March 1, 2018. It is hosted on the NASA EarthData platform.
Thirteen sample points of chlorophyll a concentration are collected within the Ross Sea Marine Protected Area. The dataset is intended for long-term monitoring of environmental change and was contributed by the organization AMD_KOPRI. It was last updated on NASA's Earthdata platform in March 2018.
AMIGOS data from the Ross Sea Marine Protected Area documents meteorological conditions at Adelie penguin breeding sites. The dataset was created by the Korea Polar Research Institute (KOPRI) and last updated in February 2018. It supports ecosystem research for the Antarctic region.
An AMD_USAPDC project investigated crystal orientation fabrics in ice sheets and their relation to stratigraphic disturbances. Research developed uncertainty estimates for fabric parameters and applied them to data from the WAIS Divide, WAIS, Siple Dome, and NEEM ice cores. The project concluded in 2017.
Bio-logger data records the foraging behavior of Adelie Penguins within the Ross Sea Marine Protected Area. The dataset includes metrics such as radius of action and dive depth to analyze feeding site usage. It was collected by the Korea Polar Research Institute (AMD_KOPRI) and last updated in December 2017.
R code and models for fitting penalised splines to species response curves and estimating ecological niche parameters. The resource includes two R2OpenBugs models, R execution scripts, and three example data files on Antarctic mosses. It was created by the Australian Antarctic Data Centre and published in 2016.
Atmospheric Infrared Sounder (AIRS) mid-tropospheric carbon dioxide retrievals, gridded monthly at 2.5° longitude by 2° latitude resolution. The product contains mean CO2 mole fractions, standard deviations, and data counts for each grid cell, produced by NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC). Data collection occurred via the AIRS instrument aboard the Aqua satellite, with the last update recorded in February 2017.
1900-2016 modeled historical exposure of U.S. offshore, coastal, and international waters to tropical cyclone activity within the North Atlantic and Pacific Ocean basins. The data, from NOAA NCEI, quantifies exposure using intersecting storm tracks, overlapping wind intensity areas, and mathematical return intervals based on a grid of BOEM Outer Continental Shelf Lease Blocks. It uses a subset of the International Best Track Archive for Climate Stewardship (IBTrACS) for storm segments meeting specific basin, date, and intensity criteria.
An R data file contains a hierarchical switching state-space model of pygmy blue whale Argos-collected telemetry data. The model estimated location states at regular 3-hour intervals and behavioral states for each location. Satellite tags were deployed on whales in the Bonney Upwelling region, SA, between 7 January and 16 March 2015.
Forest Access Roads 2013 is a nationwide geospatial dataset of truck-accessible forest roads in Switzerland, updated through a 2013-2014 survey. The Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) manages the data, which was collected by interviewing staff from approximately 800 local forest services. Information on road trafficability for specific truck categories is attached to geometries from the swissTLM3D base map.
CCAMLR Statistical area boundaries define reporting zones for fishery statistics in the Southern Ocean. The dataset covers three major FAO statistical areas (48, 58, 88) which are further subdivided into subareas and divisions. The CCAMLR Secretariat created this subset, which was last updated in 2013.
Total electron content measurements in the ionosphere were recorded at the KSS station in Antarctica during 2015. The dataset facilitates a study of statistical characteristics of the ionosphere at southern high latitudes. AMD_KOPRI, the Korea Polar Research Institute, provided this data.
Total electron content data captures ionospheric conditions over Kiruna, Sweden, a key high-latitude site for space weather research. The dataset was collected by AMD_KOPRI and captures observations from the year 2015. It supports statistical analysis of ionospheric variability.
A tool from ENVIDAT released in 2016 for assessing fire selectivity using Monte Carlo simulations. It evaluates relationships between fire occurrence and topographic factors like altitude, slope, and aspect, as well as land use categories such as forest type and distance to infrastructure. The dataset is hosted on NASA EarthData.
2011-12 austral season data maps subsurface resistivity structure to depths of about 300 meters in the McMurdo Dry Valleys and Cape Barne region. The dataset was collected via a helicopter-mounted SkyTEM system by researchers funded by NSF award 1344348 and made accessible by 2015. It distinguishes between resistive materials like glacier ice and bedrock and conductive materials like unfrozen sediments.
A 2011-12 airborne transient electromagnetic survey mapped subsurface resistivity in Antarctica's McMurdo Dry Valleys and Cape Barne region. The project, funded by NSF award 1344349 and conducted by researchers using the SkyTEM system, aimed to characterize subsurface hydrology and potential microbial habitats. Data products from this survey were made accessible to the research community.
TRMM/PR L3 Monthly Surface Rain is produced by the Japan Aerospace Exploration Agency (JAXA) from the Precipitation Radar (PR) sensor onboard the TRMM satellite. The data provides monthly rainfall, rain rate averages, standard deviation, and probability distribution functions on a 5-degree by 5-degree global grid at three height layers (2 km, 4 km, and 6 km). The current product version is Version 7, with the last metadata update recorded on 2015-04-02.
Utah public library data from the FY2010 Public Library Service survey administered by the Utah State Library Division. The dataset includes metrics on collections, finances, programs, and operations reported to the Institute of Museum and Library Services. It was last updated on the opendata.utah.gov platform in December 2014.
