Globorotalia truncatulinoides Trace Element Geochemistry (Barium, Magnesium, Strontium, Manganese, and Calcium) from the Gulf of Mexico Sediment Trap

Observations of elevated barium-to-calcium ratio (Ba/Ca) in Globorotalia truncatulinoides have been attributed to contaminant phases, deep calcification depth and diagenetic processes. U.S. Geological Survey (USGS) scientists and their collaborators investigated intra- and inter-test Ba/Ca variability in the non-spinose planktic foraminifer, G. truncatulinoides, from a sediment trap time series (2009-2017) in the northern Gulf of Mexico (generally 27.5°N and 90.3°W) to gain insights into the environmental influences on barium enrichment in this and other non-spinose species. Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) was used to differentiate between the elemental composition of the crust and lamellar calcite in non-encrusted (&lt; 150 meters [m] calcification depth) and encrusted (&gt; 250 meters calcification depth) specimens of G. truncatulinoides. For further information regarding data collection, processing methods, and/or results and interpretive study refer to Richey and others (2022).

Raw and modified raw continuous resistivity profile data collected in Northport Harbor on Long Island, New York on May 14, 2008

An investigation of coastal groundwater systems was performed along the north shore of Long Island, New York during May 2008 to constrain nutrient delivery to Northport Harbor and Manhasset Bay by delineating locations of likely groundwater discharge. The embayments are bounded by steep moraines and are underlain by thick fine-grained sediments deposited in proglacial lakes during the last ice age. Beach sand and gravel overlie the glacial deposits along the coast. The continuous resistivity profiling (CRP) surveys that were conducted indicate the existence of low-salinity groundwater in shore-parallel bands, typically 25 to 50 meters wide, along the shorelines of both bays. Piezometer sampling and seepage meter deployments in intertidal and subtidal areas of the two bays confirmed the presence and discharge of brackish and low-salinity groundwater. The large tidal ranges (up to 3 meters), and the steep onshore topography and hydraulic gradients are important variables controlling coastal groundwater discharge in these areas. For more information on the survey involved in this project, see https://cmgds.marine.usgs.gov/fan_info.php?fan=2008-007-FA.

SIR 2014-5076, Land-Cover Data for Red Rock Canyon National Conservation Area and Coyote Springs, Piute-Eldorado Valley, and Mormon Mesa Areas of Critical Environmental Concern, Clark County, Nevada

Four polygon vector data sets and one related table describe land-cover in Red Rock Canyon 
National Conservation Area (RRC_NCA_p) and Coyote Springs (CS_ACEC_p), Piute-Eldorado 
Valley (PEV_ACEC_p), and Mormon Mesa (MM_ACEC_p) Areas of Critical Environmental 
Concern, Clark County, Nevada. One polygon vector data set per Area is attributed with land-
cover at the vegetation stand level (abbreviated with a stand code) and the corresponding 
alliance level of the National Vegetation Classification Standard (NVC; Federal Geographic 
Data Committee, 2008). The table (tbl_NVC) is related to each of the four polygon data sets 
and contains the NVC classification from the group to class level. DigitalGlobe's QuickBird 
multispectral satellite imagery was classified with field vegetation data (Charlet and others, 
2014) collected at the stand level using Visual Learning Systems' Feature Analyst feature 
extraction software. Non-vegetation data layers, such as roads and disturbed areas, were 
manually delineated from the QuickBird imagery. The process steps have been generalized 
to apply to all study areas. Details about processing, such as vegetation samples used for 
training input and major changes made during photo interpretation are detailed in the larger 
work. For simplicity, the process dates are listed as the final publication date. Red Rock 
Canyon National Conservation Area was processed during 2008, Coyote Springs Area of 
Critical Environmental Concern during 2011, Piute-Eldorado Valley Area of Critical 
Environmental Concern during 2012, and Mormon Mesa Area of Critical Environmental 
Concern during 2013.

Continental Margin Mapping Program (CONMAP) sediments grainsize distribution for the United States East Coast Continental Margin (CONMAPSG)

Sediments off the eastern United States vary markedly in texture - the size, shape, and arrangement of their grains.  However, for descriptive purposes, it is typically most useful to classify these sediments according to their grain-size distributions. Starting in 1962, the U.S. Geological Survey (USGS) and the Woods Hole Oceanographic Institution (WHOI) began a joint program to study the marine geology of the continental margin off the Atlantic coast of the United States. As part of this program and numerous subsequent projects, thousands of sediment samples were collected and analyzed for particle size.
The sediment map of the Continental Margin Mapping Program (CONMAP) series is a compilation of grain-size data produced in the sedimentation laboratory of the Woods Hole Science Center (WHSC) of the Coastal and Marine Geology Program (CMGP) of the U.S. Geological Survey (USGS) and from both published and unpublished studies.  Sediment was classified using the Wentworth (1929) grain-size scale and the Shepard (1954) scheme of sediment classification. Certain grain-size categories are combined because of the paucity of some sediment textures; blank parts of the maps indicate areas where data are insufficient to infer sediment type. Bathymetry is used as a guide in placing some of the contacts between different sediment types.  However, because the true boundaries between sediment types are probably highly irregular or gradational, because the extreme textural variability that characterizes some areas does not appear at this scale, and because the accuracy of the navigational systems used during the earlier studies is limited, all contacts should be considered to be inferred.
The sediment classification for any given polygon (i.e. area) reflects the dominant surficial sediment type for that polygon.  It does not mean that other sediment types are not present within the polygon, only that the dominant sediment type is the one that is most common.

Shorelines Extracted from 1984-2015 Landsat Imagery: Petit Bois Island, Mississippi (Polyline:  Combined Dates)

Shorelines Extracted from 1984-2015 Landsat Imagery: Petit Bois Island, Mississippi (Polyline: Combined Dates) is a line shapefile representing shorelines generated from satellite imagery that was collected from 1984 to 2015.  The sample frequency of satellite imagery is much higher, and the coverage much greater, than most routine high-resolution topographic surveys.  Certain aspects of barrier island morphology, such as island size, shape and position, can be determined from these images and can indicate erosion, land loss, and island breakup.  Studying how these characteristics evolve will help develop an understanding of how barrier islands will respond to climate change, sea level rise, and major storms in the future and that will serve to improve management of our coastal resources.

Streamflow gain/loss in the Republican River Basin, Nebraska, July 1975

This arc and point data set contains streamflow-measurement sites and
reaches indicating streamflow gain or loss under base-flow conditions along
Republican River tributaries in Dundy and Chase Counties, Nebraska during
July 14 to 18, 1975 (U.S. Geological Survey, 1976).  The streamflow measurements
were made to obtain data on ground-water/surface-water interaction.  Flow
was observed visually to be zero, was measured, or was estimated at
55 sites.  Tributaries were followed upstream until the first road
crossing where zero flow was encountered. For selected streams, points
of zero flow upstream of the first zero flow site also were checked.
Streamflow gain or loss for each stream reach was calculated by
subtracting the streamflow values measured at the upstream end of
the reach and values for contributing tributaries from the
downstream value.  The data obtained reflected base-flow conditions
suitable for estimating streamflow gains and losses for
stream reaches between sites.
This digital data set was created by manually splitting the lines
from a 1:250,000 hydrography data set (Soenksen and others, 1999) at
every streamflow-measurement site.  Each set of stream segments between
measurement sites was assigned a unique reach number.

Digital Shoreline Analysis System version 4.1 Transects with Long-Term Rate Calculations for the New England South region from Dartmouth, Massachusetts to Napatree Point, Rhode Island (NewEnglandS_LT.shp)

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  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 open-ocean 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.

GAK_Q44.TIF - Gulf of Alaska U.S. EEZ GLORIA sidescan-sonar data mosaic (14 of 30) (LCC, 50 m, WGS84)

GLORIA data for the Gulf of Alaska Exclusive Economic Zone (EEZ) were acquired during five cruises over a four year period. The first cruise conducted in 1986 (F-1-86-GA) surveyed an area of the north-central mosaic area and covered an area of approximately 40,000 square kilometers (sq km). The second two cruises (F-8-88-AA, F-9-88-WG) were conducted in 1988. One of the 1988 cruises (F-8-88-AA) focused on a survey of the Aleutian Arc. The eastern most portion of that survey extended outside of the Aleutian Arc survey area and covered an area of approximately 52,000 square kilometers (sq km) of seafloor on the western edge of the Gulf of Alaska. The final two cruises (F-6-89-GA, F-7-89-EG) were completed in 1989. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. Thirty digital mosaics with a 50-meter pixel resolution were completed for the region.
