BS_Q15.TIF - Bering Sea U.S. EEZ GLORIA sidescan-sonar data mosaic (15 of 30) (LCC, 50 m, Clarke1866)

In 1984, the U.S. Geological Survey (USGS), Office of Marine Geology, launched a program using the Geological LOng-Range Inclined Asdic (GLORIA) sidescan-sonar system to study the entire U.S. Exclusive Economic Zone (EEZ). From 1986 through 1989, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted several surveys within the U.S. EEZ off Alaska. Four surveys during that time period (1986-1987) focused on the Bering Sea region. The results of these surveys were 30 digital mosaics of a 3 degree by 2 degree area with a 50-meter pixel resolution.

High-Resolution Seismic-Reflection Profiles in SEG-Y and JPEG Formats From the Cruise RAFA07034 in the Vicinity of Woods Hole, Offshore Massachusetts

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Massachusetts Office of Coastal Zone Management (MA CZM), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities along this part of the Massachusetts coastline, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from multibeam echo-sounder and sidescan-sonar data collected in the vicinity of Woods Hole, a passage through the Elizabeth Islands, off Cape Cod, Massachusetts.  In November 2007, bottom photographs, high-resolution seismic-reflection data, and Surficial sediment data were acquired as part of a ground-truth reconnaissance survey.

Single-Beam Bathymetry Data Collected in March 2021 from Grand Bay and Point Aux Chenes Bay, Mississippi/Alabama

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) in St. Petersburg, Florida, conducted a bathymetric survey of Point Aux Chenes Bay and a small portion of Grand Bay, Mississippi/Alabama, from March 3-6, 2021. Efforts were supported by the Estuarine and MaRsh Geology project (EMRG), and the data described will provide baseline bathymetric information for future research investigating wetland/marsh evolution, sediment transport, and recent and long-term geomorphic change. The data will also support modeling of future changes in response to restoration efforts and storm impacts. During this study, bathymetry data were collected aboard two personal watercrafts (PWC) outfitted with single-beam echosounders.

Sedimentary Data Collected in November 2015 From Old Tampa Bay, Florida (U.S. Geological Survey Field Activity Number 2015–341–FA)

The toxic dinoflagellate Pyrodinium bahamense (P. bahamense) produces recurring, persistent summer algal blooms in Old Tampa Bay, Florida, which degrade water quality and are potentially harmful to humans if contaminated shellfish is consumed. As part of its life cycle, P. bahamense produces dormant cysts, which settle to the seafloor, forming seed beds that may initiate future blooms if favorable conditions for germination occur.
From August 2015 to September 2016, the U. S. Geological Survey (USGS) and Florida Fish and Wildlife Conservation Commission (FWC) collaborated to conduct seasonal sediment sampling at in Old Tampa Bay, Florida. Sediment cores were collected at three sites. The USGS characterized bottom sediment texture and measured profiles of naturally-occurring radionuclides in the uppermost five centimeters of the sediment column. This information will provide an assessment of sediment accumulation, depositional focusing, and resuspension in relation to the potential impact on the seeding potential of P. bahamense cysts. This data will be used in conjunction with FWC research on the vertical distribution of cyst abundance and viability to estimate the seeding potential of future blooms (Lopez and others, 2015). This project was funded by the Tampa Bay Environmental Restoration Fund.
This data release is an archive of USGS field data and laboratory analytical results  for the five sampling periods in this study, designated as USGS Field Activity Numbers 2015-329-FA (project ID 15FWR02), 2015-341-FA (project ID 15FWR03), 2016-312-FA (project ID 16FWR04), 2016-327-FA (project ID 16FWR05), and 2016-350-FA (project ID 16FWR06).

Modeled Top of the Grande Ronde Basalt Geomodel Unit (grtop_f)

The grtop_f grid represents the modeled elevation of the top of the Grande Ronde Basalt geomodel unit 
at a 500 foot resolution. It is one grid of a geomodel that consists of eleven grids and a spatial extent 
polygon shapefile. As part of a U.S. Geological Survey Groundwater Resources Program study, a 
three-dimensional geomodel was constructed for approximately 53,000 mi2 of the Columbia Plateau 
in Washington, Oregon, and Idaho. This geomodel was constructed to define the general aquifer system 
geometry for use in a regional numerical groundwater flow model. Simplifications and assumptions 
consistent with this ultimate goal and the uncertainty in the available data were made. The geomodel 
units consist of Miocene age Columbia River Basalt Group strata and younger alluvial overburden 
covering approximately 44,000 mi2. Data were compiled from numerous databases and detailed 
studies completed during the past three decades. These data include stratigraphic interpretations 
made on more than 13,000 wells and a contiguous compilation of surficial geology and structural 
features spanning the study area. These data were simplified and used to construct piecewise-smooth 
trend surfaces that represent upper and lower subsurface geomodel unit boundaries in this complex 
folded and faulted terrain.  The smoothness of the surfaces implicitly represents uncertainty in prediction 
of each surface resulting from data gaps, errors in borehole interpretations, errors in mapped contact 
locations, and uncertainty in the shape of the paleo-surface upon which flood basalts were emplaced. 
Using a rule-based algorithm, surfaces were then recombined to construct a fully three-dimensional 
model with a 500-foot grid resolution that is consistent with the data and for which error estimates 
may be made. The modeling process yielded improved estimates of unit volumes, refinement of 
location of large structural features, and identification of features that may be important for ongoing 
groundwater studies.

LANDFIRE Remap Forest Canopy Bulk Density (CBD) Micronesia

LANDFIRE’s (LF) 2016 Remap (Remap) Canopy Bulk Density (CBD) describes the mass of available canopy fuel per unit canopy volume that would burn in a crown fire. A spatially explicit map of CBD supplies information used in fire behavior models to determine the spread characteristics of crown fires across the landscape. The CBD mapping process derives field referenced estimates of canopy characteristics through LF Reference Database (LFRDB) plot analysis. Utilizing the LFRDB plots, field referenced CBD values are computed for each plot with the canopy fuel estimation software FuelCalc. In FuelCalc, for tree species that have no crown biomass, an equation for a species with a similar genus is used as a substitute. Species widely considered to be resistant to fire are excluded, for example, Acer and Populus spp. are excluded from the canopy fuel profile because these species are considered relatively inflammable and therefore unavailable. 
CBD has a series of post-processing techniques and logic checks ensuring it is relevant in the context of other fuel products and fire behavior predictions. All non-forest values and non-burnable types such as urban, barren, snow and ice, and agriculture are coded as 0. Some stands dominated by broadleaf species which typically do not permit initiation of crown fire (e.g. Populus spp.) are coded with a CBD of 0.01 kg m-3.  In some instances, LF Remap assumes the potential burnable biomass in the tree canopy has been accounted for in the surface fuel model. For example, young or short conifer stands where the trees are represented by a shrub type fuel model will not have canopy characteristics. 
LF Remap Annual Disturbance products are incorporated into CBD to provide informed changes by disturbance type, severity, and time since disturbance (TSD). Annual Disturbance products provide a pre-disturbance scenario represented by LF Remap existing vegetation products. Reporting of the pre-disturbance scenario helps to calculate CBD, with information about vegetation type, cover, and height impacted by a disturbance. With the use of Annual Disturbance products, CBD also has capable fuels functionality. Capable fuels calculate TSD assignments for disturbed areas using an "effective year." For example, year 2020 fuels may be calculated for the year 2020. the new process considers all the existing disturbances included in LF Remap and adjusts the TSD for these to the effective year (2020 in the example), making the products "2020 capable fuels." More information about capable fuels can be found at https://www.landfire.gov/lf_remap.php.

Acquisition and observation logs for seabed video and sediment samples from Stellwagen Bank during U.S. Geological Survey field activity 2014-015-FA, aboard the R/V Auk, May 22-23 and 29-30, 2014

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen Bank National Marine Sanctuary, and the data collected will aid research on the ecology of fish and invertebrate species that inhabit the region. The Sanctuary's research vessel, R/V Auk, visited 48 locations on Stellwagen Bank at which a customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a CTD was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties.

Raw HYPACK navigation logs (text) collected by the U.S. Geological Survey - Woods Hole Coastal and Marine Science Center offshore of the Elizabeth Islands, MA, 2010

These data were collected under a cooperative agreement between the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHCMSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of seafloor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of coastal Massachusetts, primarily in water depths of 2-30 meters. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (&lt;http://woodshole.er.usgs.gov/project-pages/coastal_mass/&gt;). The data collected in this study area located around the western extent of the Elizabeth Islands includes high resolution bathymetry, acoustic-backscatter intensity, seismic-reflection, and navigation data. These data were collected during a nearshore cruise in September 2010 onboard the R/V Rafael using the following equipment: an SEA Ltd SwathPlus interferometric sonar (234 kHz), Klein 3000 dual frequency sidescan sonar, an Edgetech 424 chirp subbottom profiling system, and 4 GPS antennae.

CentralBeaufort_shorelines.shp - Shorelines for the northern Alaska coastal region used in shoreline change analysis, 1947 to 2007

The Arctic Coastal Plain of northern Alaska is an area of strategic economic importance to the United States, is home to remote Native American communities, and encompasses unique habitats of global significance. Coastal erosion along the north coast of Alaska is chronic, widespread, may be accelerating, and is threatening defense and energy-related infrastructure, natural shoreline habitats, and Native communities. There is an increased demand for accurate information regarding past and present shoreline changes across the United States. To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.
There is no widely accepted standard for analyzing shoreline change. Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments. The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast. The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.
