Summary of Suspended-Sediment Concentration Data, San Francisco Bay, California, Water Year 2002 presents data collected by the USGS from October 2001 through September 2002. Optical backscatterance sensors and water samples were used to monitor suspended sediment at ten sites across Suisun, San Pablo, Central, and South San Francisco Bay. The report includes the data-collection methods, calibration curves, and edited data plots for each sensor.
Optical Plankton Counter data provides counts and size estimates of zooplankton-sized particles, including abundance, total carbon biomass, and biomass per size class. Measurements were collected along standard ship sections off Oregon and Northern California during four cruises in 2000 and 2002. The dataset was produced by the SCIOPS organization.
Storglaciaren in Arctic Sweden was surveyed in July 2001 and 2002 using ground-based ice-penetrating radar at 50 and 100 MHz frequencies. The data consist of closely spaced grids from four locations, acquired to study how water moves from the glacier surface to its bed through cavities and conduits. The radar portion of this project was carried out by St. Olaf College.
Geochemical and petrographic data from mafic volcanic rock samples collected in Palmer Land and Graham Land, Antarctica. The dataset includes field information, petrography, and raw geochemical measurements from multiple analytical techniques. It was produced by SCIOPS using archived material from the British Antarctic Survey, with data primarily from the 2001/02 period.
Measurements performed at the BTN (Icaro Camp) station in the austral summer of 2001-2002. Data includes aerosol optical depth derived from a PREDE POM 01L sun-photometer at six wavelengths and direct solar radiative flux. The dataset was collected by the SCIOPS organization under cloudless-sky conditions.
NASA Earthdata hosts optical borehole logging measurements from the Siple Dome A site in Antarctica. The data set contains high-resolution logs of dust and microbial particles detected in glacial ice, with information on depth and optical signal. Data were collected by AMD_USAPDC and last updated in February 2002.
Salinity maps for Florida Bay show surface salinity at 5ppt intervals from November 1994 through December 2001 and bottom salinity for 1994-1996. The dataset was created by CEOS_EXTRA and last updated in December 2001. It was developed to understand sediment resuspension, bathymetric change, and water quality impacts from algal blooms and seagrass mortality.
Daily lidar observations from Davis Station, Antarctica, measure the occurrence and altitude limits of Polar Stratospheric Clouds (PSCs). The data, collected by the AU_AADC, are considered obsolete and were last updated in 2001. It provides condition indicators for studying cloud formation linked to ozone depletion chemistry.
SeaWiFS (Sea-viewing Wide Field-of-view Sensor) provides quantitative data on global ocean bio-optical properties to the Earth science community. The dataset is designed to look at our planet from space to better understand it as a system. It was last updated on December 31, 2001.
Florida Bay surface and bottom salinity data, with some temperature and conductivity readings, collected from November 1994 through November 2001. The dataset includes point ID, date, salinity values in ppt, and longitude/latitude coordinates. Data was collected by the CEOS_EXTRA organization and is hosted on NASA EarthData.
Irish Marine Institute data for monitoring harmful algal events includes biotoxin measurements, phytoplankton species counts, and remote sensing imagery. It was compiled by the Marine Institute and NOAA/NOS, with records from at least 1998 to 2001. The dataset supports early warning systems for shellfish safety and public health.
Annual Layers at Siple Dome, Antarctica, from Borehole Optical Stratigraphy contains measurements of annual snow layer depths and firn optical brightness. The dataset was gathered by researchers from the AMD_USAPDC organization and published via NASA Earthdata. The data were last updated in November 2001.
Over 23 days from August 13 to September 5, 2001, the Pacific 2001 Air Quality Study collected gaseous, particle, and meteorological data at the Sumas Eagle Ridge site. Measurements were made by the LARC_ASDC organization to study aerosol types, sources, and interactions between biogenic emissions and urban pollution.
July 10 to August 2, 2001 data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument provides aerosol optical thickness over oceans and continents. The dataset, collected during the CLAMS experiment and produced by LARC_ASDC, offers high spatial resolution with 1-km pixels at nadir across 36 spectral bands. It covers a spatial region from approximately -106 to -42 degrees longitude and 18 to 57 degrees North latitude.
Vaisala RS-80 Radiosonde data was collected at the Chesapeake Lighthouse platform during the CLAMS experiment. The dataset was gathered by the LARC_ASDC organization to validate satellite retrievals of cloud and aerosol properties. The last recorded update for this dataset was in August 2001.
CAR CLAMS BRDF Measurements V2 contains bidirectional reflectance factor observations from the CAR instrument during the July-August 2001 CLAMS field campaign. The campaign, sponsored by NASA CERES, MISR, MODIS-Atmospheres, and GACP, aimed to validate Terra satellite data products. Data collection focused on clear-sky conditions at the Chesapeake Lighthouse sea platform.
CLAMS field campaign data supports validation of Terra satellite products from NASA's EOS program. Measurements from July 2001 focus on clear-sky conditions at a sea platform 20 km east of Virginia Beach. The campaign was sponsored by CERES, MISR, MODIS-Atmospheres, and GACP teams.
Ionospheric absorption data derived from cosmic noise measurements at 30 MHz and 38.2 MHz by riometers. The dataset originates from the Italian Antarctic Base at Terra Nova Bay, with installations beginning in the austral summer of 1993-94 and automatic data acquisition starting in February 1995. It was provided by the organization SCIOPS and last updated in early 2001.
2000 data from a USGS study enhancing thermal maturity maps for the Appalachian Basin in New York. It establishes new subsurface data points for conodont alteration index (CAI) and vitrinite reflectance (%Ro) from Ordovician and Devonian rock units. The data is part of a larger, ongoing project that will include data from several adjoining states.
SeaWiFS satellite data from 2000 provides quantitative measurements of global ocean bio-optical properties. The sensor was designed to observe Earth as a system to understand its behavior and evolution. The dataset was provided by AMD_KOPRI and last updated on December 31, 2000.
