Grain-Size Analysis Data from Sediment Samples in Support of Oceanographic and Water-Quality Measurements in the Nearshore Zone of Matanzas Inlet, Florida, 2018

The interactions of waves and currents near an inlet influence sediment and alter sea-floor bedforms, especially during winter storms. As part of the Cross-Shore and Inlets Processes project to improve our understanding of cross-shore processes that control sediment budgets, the U.S. Geological Survey deployed instrumented platforms at two sites near Matanzas Inlet between January 24 and April 13, 2018. Matanzas Inlet is a natural, unmaintained inlet on the Florida Atlantic coast that is well suited for study of inlet and cross-shore processes. The study sites were offshore of the surf zone in a line perpendicular to the coast in water depth from 9 to 15 meters. An instrumented sea-floor platform was deployed at each site to measure ocean currents, wave motions, acoustic and optical backscatter, temperature, salinity, and pressure with an emphasis on quantifying the forcing for sediment transport and response near the seabed. Sonars mounted on the platform at the shallow site recorded how the sea-floor bedforms responded to forcing conditions. A surface buoy was deployed at each site; the larger buoy at the deeper site supported meteorological measurement of local atmospheric conditions during the study, and both buoys measured near-surface water temperature and salinity. Sediment samples were collected at the study sites to support these oceanographic and water-quality measurements, and grain size was analyzed for use in sediment transport models to compare predicted estimates of sediment resuspension and transport with observed estimates.  Grain-size results are presented in phi and μm units.

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the offshore East Africa and Seychelles region. The Assessment Unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources.  The Assessment Unit is defined within the context of the higher-level Total Petroleum System.  The Assessment Unit is shown herein as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type.  The Assessment Unit boundary is defined geologically as the limits of the geologic elements that define the Assessment Unit, such as limits of reservoir rock, geologic structures, source rock, and seal lithologies.  Machine-readable tables are provided that contain the input and results for each assessment unit summarized in the USGS Fact Sheet. Methodology of assessments are documented in USGS Data Series 547 for continuous assessments (https://pubs.usgs.gov/ds/547) and USGS DDS69-D, Chapter 21 for conventional assessments (https://pubs.usgs.gov/dds/dds-069/dds-069-d/REPORTS/69_D_CH_21.pdf).

Digital elevation model of the lava dome in the crater of Mount St. Helens on October 20, 1988

The catastrophic, explosive eruption of Mount St. Helens, Washington, on May 18, 1980, is the most well-known eruption of the volcano. Less well known is the May 18th eruption marked the beginning of a period of eruptive activity that lasted through 1986. From October 1980 through October 1986, a series of 17 dome-building episodes added millions of cubic meters of lava to the crater floor. Most of the growth occurred when magma extruded onto the surface of the dome, forming short (650 to 1,300 feet), thick (65 to 130 feet) lava flows.
This data release is a 2-meter resolution digital elevation model (DEM) and hillshade raster derived from a previously unpublished 1:4,000 scale topographic contour map, based on aerial photographs taken on October 20, 1988, created by USGS for use during the eruption response.

Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, 2015, 2018, and 2021 Site 0560 land-water matrix

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring to determine the efficacy of these projects. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. This dataset consists of a matrix of six land-water products (2005, 2008, 2012, 2015, 2018, and 2021).  The resulting matrix has 64 possible classes defined by the combination of land and water categories on those six dates.

Sea urchin counts obtained by SCUBA at shallow nearshore sites along the north Pacific Rim from Bering Island to Southeast Alaska during 1987-2021

The data consist of counts of sea urchins in quadrats from over 600 nearshore rocky bottom sites that were sampled by scuba between 1987 and 2021. The sites are from 38 locations on the north Pacific Rim ranging from Bering Island, along the Aleutian Island chain and the Alaska Peninsula to Southeast Alaska. At each site, divers counted and collected sea urchins from quadrats placed at random distances mostly along a 20-25-foot depth contour. At a subset of sites, 40-foot depths were targeted. Urchins were counted until either 20 quadrats were sampled or about 200 urchins were collected. Quadrat size is specified in the data table but was 0.25 m2 at almost all sites. At the same sites where urchins were counted, divers counted kelps and estimated percent cover of fleshy red algae, other benthic algal cover, and non-motile invertebrates in 20 quadrats along the same depth profile. Sites were plotted at random from along the coasts of islands or areas designated. Hard substrate was targeted. Sites included here are at Adak Island, Agattu Island, Akutan Island, Alaid Island, Amchitka Island, Anangula Island, Atka Island, Attu Island, Bering Island, Chiachi Island, Chuginadak Island, Hawadax (formerly Rat) Island, Kiska Island, Kodiak Island, Mitrofania Island, Nizki Island, Ogliuga Island, Sanak Island, Seguam Island, the Semidi Islands, Shemya Island, Sitkalidak Island, Skagul Island, Tanaga Island, Umnak Island, Unalaska Island, Unga Island, Yunaska Island; Amalik Bay, Kukak Bay, and Pavlov Bay on the Alaska Peninsula; Kachemak Bay on the Kenai Peninsula; and Torch Bay, Surge Bay, and Sitka Sound in southeast Alaska.

Kelp and sea urchin data obtained by SCUBA at shallow nearshore sites along the North Pacific Rim from Bering Island to Southeast Alaska obtained over multiple decades beginning in 1987

Between 1987 and 2021, over 600 nearshore rocky bottom sites were sampled by scuba at 38 locations on the north Pacific Rim ranging from Bering Island, along the Aleutian Island chain and the Alaska Peninsula to southeast Alaska. Sites were plotted at random from along the coasts of islands or areas designated. Hard substrate was targeted. Most sites were sampled more than once, years or decades apart. Many sites in the western Aleutians were resampled several times as sea otter populations densities changed there. Each site was sampled using 20 quadrats along 20-25-foot depth contour. At a subset of sites, 40-foot depths were sampled. Divers counted kelps but non-motile invertebrates, Desmarestia spp. (acid weed), fleshy red algae, erect coralline algae, encrusting coralline algae, and encrusting Codium were each subjectively rated on a percent cover scale of 1 - 6 where 1 is 0 percent to 5 percent, 2 is 6 percent to 25 percent, 3 is 26 percent to 50 percent, 4 is 51 percent to 75 percent, 5 is 76 percent to 95 percent, and 6 is 96 percent to 100 percent. Quadrat size was 0.25 m2 at almost all sites but is specified in the data tables. At the same sites where kelps were counted, divers counted and collected sea urchins from quadrats placed at random distances along the same depth profile. Urchins were counted and collected from quadrats until either 20 quadrats were sampled or about 200 urchins were collected. Test diameters of collected urchins were measured and recorded on the surface. Sites included here are at Adak Island, Agattu Island, Akutan Island, Alaid Island, Amchitka Island, Anangula Island, Atka Island, Attu Island, Bering Island, Chiachi Island, Chuginadak Island, Hawadax (formerly Rat) Island, Kiska Island, Kodiak Island, Mitrofania Island, Nizki Island, Ogliuga Island, Sanak Island, Seguam Island, the Semidi Islands, Shemya Island, Sitkalidak Island, Skagul Island, Tanaga Island, Umnak Island, Unalaska Island, Unga Island, Yunaska Island; Amalik Bay, Kukak Bay, and Pavlov Bay on the Alaska Peninsula; Kachemak Bay on the Kenai Peninsula; and Torch Bay, Surge Bay, and Sitka Sound in Southeast Alaska. Site locations (SiteLocs.csv), sea urchin count data (UrchinCounts.csv), sea urchin size data (UrchinSizes.csv), and kelp count and bottom cover data (AKKelpData.csv) are presented in separate tables.

Nutrient balances, river loads, and a counterfactual analysis to determine drivers of Mississippi River nitrogen and phosphorus loads from 1975 to 2017

This dataset consists of input and output datasets for estimating nitrogen (N) and phosphorus (P) balances for the Mississippi River Basin from 1950 to 2017. The N balance was calculated as the difference between inputs (fertilizer, manure, wastewater treatment facility effluent, N fixation, and atmospheric deposition) and outputs (crop uptake and removal in harvest and gaseous emissions to the atmosphere). The P balance was calculated as the difference between inputs (fertilizer, manure, wastewater treatment facility effluent, and weathering) minus outputs (specifically, P harvested and removed in crops, hay, and pasture).
