Kemp's Ridley sea turtle forage location centroids in the northern Gulf of Mexico, 2010, 2011 and 2012

Following an explosion at the Deepwater Horizon drilling rig on April 20, 2010, MC252 an estimated 3.19 million barrels of oil leaked into the Northern Gulf of Mexico over 87 days. The endangered Kemp's ridley sea turtle (Lepidochelys kempii [Lk]) has a long established record of using the area near the well as primary foraging grounds. Resulting short- and long-term negative impacts of the oil spill on sea turtles could induce changes in the health and fitness of the Lk population. MC252 oil is known to have entered the foraging areas. Consequently, stable carbon and nitrogen isotope signatures from MC252 oil should be reflected in the food web and in the tissues of organisms such as sea turtles. We measured carbon and nitrogen isosope ratios of satellite-tagged turtles to 1) assess changes in foraging strategies of nesting Lk sampled in 2010 (the year of the spill) and two subsequent post-spill years; and 2) estimate the proportion of females that were within the area affected by the oil spill, the latter via discriminant analysis. Scute samples were collected using a biopsy punch from turtles nesting at a long-term study site on the Lower Texas Coast (Padre Island National Seashore) and on the Upper Texas Coast (Galveston Island to Surfside Beach). Turtles included in this study were sampled only once. δ13C values in samples obtained from turtles nesting in 2011 and 2012 were significantly depleted (F3,96=4.76, p=0.004 ) compared to 2010 samples. In contrast, there were no significant differences in δ15N among years. The depleted carbon values correlate with the depleted carbon values of MC252 oil. The distinctive isotope values of the satellite tagged females provided data with which to identify turtles that were inside the oiled area

Domestic well locations and populations served in the conterminous U.S.:1990

In this dataset we present two maps that estimate the location and population served by domestic wells in the contiguous United States. The first methodology, called the “Block Group Method” or BGM, builds upon the original block-group data from the 1990 census (the last time the U.S. Census queried the population regarding their source of water) by incorporating higher resolution census block data. The second methodology, called the “Road-Enhanced Method” or REM, refines the locations by using a buffer expansion and shrinkage technique along roadways to define areas where domestic wells exist. The fundamental assumption with this method is that houses (and therefore domestic wells) are located near a named road. The results are presented as two nationally consistent domestic-well population datasets. While both methods can be considered valid, the REM map is more precise in locating domestic wells; the REM map had a smaller amount of spatial bias (nearly equal vs biased in type 1 error), total error (10.9% vs 23.7%,), and distance error (2.0 km vs 2.7 km), when comparing the REM and BGM maps to a California calibration map. However, the BGM map is more inclusive of all potential locations for domestic wells. The primary difference in the BGM and the REM is the mapping of low density areas. The REM has a 57% reduction in areas mapped as low density (populations greater than 0 but less than 1 person per km), concentrating populations into denser regions. Therefore, if one is trying to capture all of the potential areas of domestic-well usage, then the BGM map may be more applicable. If location is more imperative, then the REM map is better at identifying areas of the landscape with the highest probability of finding a domestic well. Depending on the purpose of a study, a combination of both maps can be used. 
For space concerns, the datasets have been divided into two separate geodatabases. The BGM map geodatabase and the REM map database.

Shorelines used to calculate shoreline change statistics Boston coastal region from Carson Beach in South Boston to Weymouth River, including the Boston Harbor Islands (Boston_shorelines.shp)

Due to continued coastal population growth and increased threats of erosion, current data on trends and rates of shoreline movement are required to inform shoreline and floodplain management. The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates at 40-meter intervals along ocean-facing sections of the Massachusetts coast.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) in cooperation with the Massachusetts Office of Coastal Zone Management, has compiled reliable historical shoreline data along open-facing sections of the Massachusetts coast under the Massachusetts Shoreline Change Mapping and Analysis Project 2013 Update. Two oceanfront shorelines for Massachusetts (approximately 1,800 km) were (1) delineated using 2008/09 color aerial orthoimagery, and (2) extracted from topographic LIDAR datasets (2007) obtained from NOAA's Ocean Service, Coastal Services Center. The new shorelines were integrated with existing Massachusetts Office of Coastal Zone Management (MA CZM) and USGS historical shoreline data in order to compute long- and short-term rates using the latest version of the Digital Shoreline Analysis System (DSAS).

Longitudinal profile of the lower Cedar River, Washington, 2010.

A field survey of the lower Cedar River from Landsburg to Renton, WA was conducted on 29 April 2010 from a raft using real-time kinetic global positioning system to determine horizontal location and water surface elevation and a pressure transducer to measure depths along the thalweg of the river. These data were averaged over 100 m intervals to generate water surface elevations, river bed elevations, and depths at regular 10-meter intervals. The water surface and river bed gradients were calculated using the water surface elevations 10 m upstream and 10 m downstream of each point. Each point was assigned as a pool, riffle, or other type. Observations of salmon redds during the fall of 2010 are indicated.

Lower Cedar Alcoves 2013

Alcoves are small embayments found along a river's edge. They are found at the downstream end of gravel bars, tributary confluences, and other localized channel expansions. Alcoves generally have low velocities because they are protected from the main current, though they may "wash out" at higher flows. Alcoves are a type of off-channel habitat that are used by juvenile salmon for rearing.

ViTexOCR; a script to extract text overlays from digital video

The ViTexOCR script presents a new method for extracting navigation data from videos with text overlays using optical character recognition (OCR) software. Over the past few decades, it was common for videos recorded during surveys to be overlaid with real-time geographic positioning satellite chyrons including latitude, longitude, date and time, as well as other ancillary data (such as speed, heading, or user input identifying fields). Embedding these data into videos provides them with utility and accuracy, but using the location data for other purposes, such as analysis in a geographic information system, is not possible when only available on the video display. Extracting the text data from imagery using software allows these videos to be located and analyzed in a geospatial context.
The script allows a user to select a video, specify the text data types (e.g. latitude, longitude, date, time, or other), text color, and the pixel locations of overlay text data on a sample video frame. The script’s output is a data file containing the retrieved geospatial and temporal data. All functionality is bundled in a Python script that incorporates a graphical user interface and several other software dependencies.

Attributes for NHDPlus Version 2.1 Reach Catchments and Modified Routed Upstream Watersheds for the Conterminous United States:  Estimates of Subsurface Tile Drainage Extent for the Conterminous United States, Early 1990s

This tabular data set represents the estimated percent area of subsurface tile drainage extent from the early 1990's compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID.  The source data are "Estimates of subsurface tile drainage extent for the conterminous United States, early 1990s" produced by the United States Geological Survey Nakagaki, 2016). Units are percent of catchment. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions.  Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2016).
