Northeastern Illinois (NEIL) Six County Airborne Lidar Validation Survey Data Northeastern Illinois (NEIL) Six County Airborne Lidar Validation Survey Data
Airborne light detection and ranging (lidar) can provide high-quality topographic information over large areas. Lidar is an active remote sensing technology that employs laser ranging in near-infrared and green spectral wavelengths to provide three-dimensional (3D) point information for objects, including Earth's surface, vegetation, and infrastructure. The U.S. Geological Survey (USGS)...
Magnetotelluric and gravity data from the Northwest Geysers, California Magnetotelluric and gravity data from the Northwest Geysers, California
This dataset consists of 42 magnetotelluric (MT) stations collected in 2017 in the Northwest Geysers, CA and 534 gravity stations collected in 2017 and 2019. The U.S. Geological Survey acquired these data as part of a project to image the heat source in the Northwest Geysers. Support was from the U.S. Geological Survey's Volcano Hazards Program.
Time Series of Autonomous Carbonate System Parameter Measurements from Crocker Reef, Florida, USA Time Series of Autonomous Carbonate System Parameter Measurements from Crocker Reef, Florida, USA
This dataset contains carbonate system data collected by scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center to investigate the effects of carbon cycling, coastal and ocean acidification at Crocker Reef located along the Florida Keys Reef Tract, in Southeast Florida, USA. These data were collected using an autonomous instrument called the...
North Pacific Pelagic Seabird Database (NPPSD) North Pacific Pelagic Seabird Database (NPPSD)
The North Pacific Pelagic Seabird Database (NPPSD) is maintained by the USGS Alaska Science Center and includes survey transect data designed and conducted by numerous partners primarily to census seabirds at sea. The data provided here relate to observations of marine birds and mammals observed during at-sea surveys throughout the North Pacific including the Arctic Ocean, Beaufort Sea...
Chalk Cliffs Channel Surveys derived from Structure-from-Motion Chalk Cliffs Channel Surveys derived from Structure-from-Motion
This data release contains two point clouds derived from structure-from-motion photogrammetry. The first survey was conducted on 10 September 2015 and the second survey was conducted on 1 June 2016. Each survey was designed to capture a 35-meter channel reach using digital photos (1187 photos were taken in the first survey and 1085 photos were taken in the second survey). Twenty-five...
Forest structure, regeneration, and soil data to support mangrove forest damage assessment on St. John, U.S. Virgin Islands, from Hurricane Irma (2018-2019) Forest structure, regeneration, and soil data to support mangrove forest damage assessment on St. John, U.S. Virgin Islands, from Hurricane Irma (2018-2019)
These data support efforts to assess mangrove forest structural response to Hurricane Irma. Data were collected from within Virgin Islands National Park in St John, U.S. Virgin Islands. Datasets include measurements of forest inventory and vitality status, woody debris, regeneration assessment, and organic soil carbon.
