This data set provides classified land cover transition images (maps) derived from Landsat Thematic Mapper (TM) and Multispectral Scanner (MSS) imagery for Ariquemes, Luiza, and Ji-Parana areas in Rondonia, Brazil, at 30-m resolution. Images depict the age relative to the year 2000, of cleared land from the date the land was cut, to the date when primary forests transitioned into nonforest class (for example, 25 = cut by 1975, or 25 years before the year 2000). Temporal changes in three regions are represented by 31 TM scenes acquired between 1984 and 1999, and a pair of MSS scenes from 1975 and 1978. Data are provided as three GeoTiff (*.tif) images, one for each of the three areas.

The Integrated Science Data Management (ISDM) office processes oceanographic profiles reported for the world oceans in near real-time from the Global Telecommunications System (GTS) for the Global Temperature and Salinity Profile Program (GTSPP). These data also support the activities of the Ship-of-Opportunity Programme Implementation Panel (SOOPIP) and the WOCE Upper Ocean Thermal Program (WOCE UOT).

The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information. NOAA is responsible for archiving and distributing the source data as described in this metadata record.

Multibeam backscatter imagery extracted from gridded bathymetry of Maro Reef, Northwestern Hawaiian Islands, USA. These data provide coverage between 20 and 5000 meters. The backscatter dataset includes data collected using Simrad EM300, Simrad EM3002d, Simrad EM120, and Reson 8101 multibeam sonars. The sonars frequencies are 30 kHz, 300 kHz, 12 kHz, and 240 kHz respectively and the backscatter data from each sonar are processed and gridded separately. These metadata are for the 5 m grid cell size Simrad em300 multibeam backscatter data only.

Crossover difference data records (XDRs) from the GEOSAT Geodetic Mission (GM) and Exact Repeat Mission (ERM) for the time period April 1, 1985 to November 7, 1987. Parameters include: time, orbit, latitude/longitude, and sea surface height. Corrections to the data include: sea level, wind and wave data, tides, dry and wet troposphere, ionosphere, height bias, altimeter crossover differences, altimeter sea surface measurement, and spacecraft orientation. These data were submitted by the U.S. Navy via National Ocean Service. The US Navy Geosat (Geodetic Satellite) radar altimeter mission lasted for nearly 5 years (March 1985 to January 1990) and collected approximately 750 million measurements of sea level, wave height, and wind speed over the global oceans. During the Geodetic Mission (March 1985 to September 1986), the satellite did not repeat its ground track for the duration of the mission. The orbit of the satellite was changed in early October 1986 to begin the Exact Repeat Mission (ERM) which lasted from November 8, 1986 until the satellite quit functioning in January 1990. During the ERM, the satellite repeated its ground track every 17 days. Data were initially processed by the Johns Hopkins University Applied Physics Laboratory in Laurel, MD in coordination with the NOAA/NOS Satellite Altimeter Group. Data products were transferred to the NOAA National Oceanographic Data Center (NODC) for distribution. Data products are archived at the NODC.

This report summarizes the background, process, results, lessons learned, and recommendations from the 2011 Wilderness Fellows Initiative. This initiative was a new effort of the U.S. Fish Wildlife Service to preserve the character of wilderness by assessing trends in wilderness character in the National Wildlife Refuge System NWRS. Two questions have been used to frame the success of this initiative: Did it work? and Was it worthwhile? Following the results, the report covers recommendations for the initiatives and for the wilderness character monitoring in the refuge system. Appendices follow, which include a summary of participating refuges, summary of wilderness character monitoring measures by refuge, summary of wilderness character monitoring measures by wilderness quality and a summary of refuge project leader responses to debriefing questions.

This data set contains the 2004 and 2010 classifications of Territory of American Samoa (Swains Island) and can be used to analyze change. This data set which utilized 1 full Quickbird multispectral scene and 1 full or partial 2010 WorldView2 multispectral scene, were analyzed according to the Coastal Change Analysis Program (C-CAP) protocol to determine land cover.
