U.S. Census Grids (Summary File 1), 2000: Metropolitan Statistical AreasEntry ID: CIESIN_SEDAC_USCG_SF1MSA
Abstract: U.S. Population Grids (Summary File 1), 2000: Metropolitan Statistical Areas contain grids of demographic and socioeconomic data from the year 2000 U.S. census in ASCII and geotiff formats for 50 metropolitan statistical areas with at least one million in population. The grids have a resolution of 7.5 arc-seconds (0.002075 decimal degrees), or approximately 250 square meters. The gridded variables ... are based on census block geography from Census 2000 TIGER/Line Files and census variables (population, households, and housing variables). This dataset is produced by the Columbia University Center for International Earth Science Information Network (CIESIN).
The data in American Standard Code for Information Interchange (ASCII) and Geographic Tagged Image File Format (GeoTIFF) and maps in Portable Document Format (PDF) and Portable Network Graphics (PNG) formats are available from the NASA Socioeconomic Data and Applications Center (SEDAC).
Purpose: To provide gridded demographic data, including characteristics of age, race, ethnicity, and housing, for metropolitan statistical areas at a finer resolution than is available in the 30 arc-second grids used for the United States as a whole.

Quality Only 17 RMT hauls were able to be made due to severe conditions. The main sampling system used was a rectangular midwater trawl (RMT 8) of 8 square meter mouth area, and 4.5 mm mesh. Initially 0-200 meter downward hauls were made, followed by 0-150m hauls. On runs between stations more than 30 nautical miles apart, a continuous underway (Hardy) plankton recorder (CPR) was used, 300 micro-meter mesh internally. Between Heard Island and Kerguelen, and after Kerguelen the CPR was deployed for normal run times of about 500 nautical miles. 17 RMT 8 shots were made, plus 11 short CPR runs of 30-50 nautical miles and 4 long CPR runs of 250-500 nautical miles. Initial examination was made on board, with the majority of the processing being completed at the Australian Antarctic Division.
