NASA Earthdata CMR2019 · collection

Starting with the most recently updated polygon shapefile of ASPAs (Terauds and Lee 2016), which contained some minor improvement on the original ASPA spatial layer first made publicly available in 2011, we first cross-checked the location of ASPA polygons with the spatially explicit locations provided in the ASPAs Management Plans. Once polygons were aligned with the Management Plans, we then geo

This data set provides global forest area, forest growing stock, and forest biomass data at 1-degree resolution for the period 1950-2010. The data set is based on a compilation of forest area and growing stock data reported in international assessments performed by FAO, MCPFE (now Forest Europe), and UNECE. Data of different assessments are to the extent possible harmonized to reflect both forest

NASA Earthdata CMR2014 · collection

This dataset is intended for general use in spatial planning and management to identify areas where benthic marine assemblages are likely to differ from each other in the Southern Ocean. We achieve this by using a hierarchical spatial classification of ecoregions, bathomes and environmental types. Ecoregions are defined according to available data on biogeographic patterns and environmental driver

NASA Earthdata CMR2013 · collection

This metadata record describes a grid system for Macquarie Island formerly used by the Parks and Wildlife Service, Tasmania. The grid was first adopted by Irynej Skira in 1974 and was based on the 1:50000 scale map of the island published by Australia's Division of National Mapping in 1971. Data was continually recorded on this system up to June 2001 when the Universal Transverse Mercator (UTM) gr
