Raster and mapping data indicating landscape change from the June 2012 storm in the Duluth, MN region

The GeoTiff raster data were created from subtraction of elevation values collected in 2012 from elevation values collected in 2011. Both data collections were conducted by airborne lidar surveys contracted by the Minnesota Department of Natural Resources. These survey occured before and after a historical rain event that cause widespread landscape change. The shapefiles are polygon objects that illustrate where erosion and deposition occurred on slopes and in valleys in the June 2012 rain event in the Duluth, MN region

Mitochondrial and microsatellite genetic data from Cape Sable seaside sparrow feather samples collected 2011-2018

The federally endangered Cape Sable seaside sparrow (Ammospiza maritima mirabilis) is endemic to the Greater Everglades ecosystem in southern Florida. The subspecies inhabits the fragmented freshwater marl prairies and contains six subpopulations (A-F), named for management purposes, since genetic information is lacking. To evaluate genetic connectivity and inform management decisions, feather samples were collected between 2011 and 2018 from 108 sparrows across five subpopulations (A-E). Sequence data for four mitochondrial DNA markers (N = 36–69) and 12 nuclear microsatellite loci (N = 55) are provided. The mitochondrial markers used were Cytochrome b (Cytb), control region D-loop, NADH dehydrogenase 2 (ND2), 16S ribosomal RNA (16S).

Apple Creek Rapid Geomorphic Assessment, Outagamie County, Wisconsin

The Fox River network, which includes Apple Creek, contributes a significant amount of total phosphorus (P), including both sediment-bound P (sed-P) and dissolved reactive P (DRP, also known as orthophosphate) and suspended sediment to Green Bay/Lake Michigan. Most headwater streams of the Fox River are predominantly agricultural in land use, interspersed with rural communities and the industrialized Fox River Valley corridor. Implementation of best management practices on agricultural operations has worked to limit the amount of material that is carried to the stream from cropland. However, several studies have shown streambank erosion to be another source of suspended sediment in these streams. These files contain the descriptions of 30 rapid geomorphic assessments conducted during the summer of 2018 as part of the Apple Creek sediment-source study. Included in the file are reach lengths, drainage area at the downstream end of the reach, an extrapolation to all stream segments upstream of the USGS gage, and sediment/phosphorus budget estimates for the basin.

Western spadefoot survey data in northern and central California (2019)

Species distributions are governed by processes occurring at multiple spatial scales. For species with complex life cycles, the needs of all life stages must be met within the dispersal limitations of the species. Multi-scale processes can be particularly important for these species, where small-scale patterns in specific habitat components can affect the distribution of one life stage, whereas large-scale patterns in land cover might better explain the distribution of other life stages. Using a conditional multi-scale model, we evaluated which aspects of the landscape and local environment are most strongly related to occupancy patterns of western spadefoots (Spea hammondii). These data describe the survey, pool, and landscape characteristics associated with surveys conducted in the spring of 2019 for western spadefoots and used to estimate the parameters of the model. Considering the processes that affect species distributions at multiple scales is an important component of effective conservation.

Geospatial datasets of the glacial geology and hydrogeology of the Owasco Inlet Watershed, Cayuga and Tompkins Counties, New York

In 2015, the U.S. Geological Survey (USGS), in cooperation with the New York State Department of Environmental Conservation (NYSDEC), began an appraisal of the sand and gravel aquifers within the Owasco Inlet watershed, which covers about 117 square miles (mi2) and drains north directly to Owasco Lake, one of New York’s Finger Lakes. About three-quarters of the watershed is within Cayuga County; the remaining area (southern end) is in Tompkins County. The Owasco Inlet valley stretches about 18 miles (mi) from Owasco Lake south to the divide at Freeville. Major tributaries include Hemlock Creek on the west side of the watershed and Dresserville and Decker Creeks on the east side.  A variety of data were compiled, collected, and synthesized to provide a broad picture of the glacial deposits, hydrogeologic framework, aquifer occurrence, and water-resource potential in the area. Geospatial datasets (shapefiles) of aquifer extents, wells, surficial geology and glacial features are detailed in child items associated with this data release.

Presence/Absence of Myxobolus inornatus, Aeromonas spp., and Flavobacterium spp. in Young-of-the-Year Smallmouth Bass with Fluorescence In Situ Hybridization

Histopathological assessments of young-of-the-year smallmouth bass (YOY SMB) in the Susquehanna River drainage identified a high prevalence of the myxozoan Myxobolus inornatus. This myxozoan infects the connective tissue of the muscle below the skin but is sometimes observed in the esophagus and buccal cavity. In some instances, shallow infections cause breaks in the skin which could increase the chance of opportunistic bacterial infections. Several microbial pathogens including Flavobacterium columnare, Aeromonas spp. and largemouth bass virus (LMBV) have also been cultured from clinically diseased YOY. A multiplex fluorescence in situ hybridization (FISH) assay was developed to determine potential co-localization of M. inornatus, Flavobacterium spp., and Aeromonas spp. infections. With FISH, 75% of YOY SMB exhibited M. inornatus infections, 10% had Aeromonas spp. infections, and 5% had Flavobacterium spp. infections, while 3% had coinfections with both bacterial species and M. inornatus. The results of the multiplex FISH assay revealed a low occurrence of coinfections of Flavobacterium spp. and/or Aeromonas spp. with M. inornatus in randomly sampled individuals.

Closed depression density in karst regions of the conterminous United States: features and grid data

Most methods for the assessment of sinkhole hazard susceptibility are predicated upon knowledge of pre-existing closed depressions in karst areas. In the United States (U.S.), inventories of existing karst depressions are piecemeal, and are often obtained through inconsistent methodologies applied at the state or county level and at various scales. Here, we present a first attempt at defining a karst closed depression inventory across the conterminous U.S. using a common methodology. Automated algorithms for extraction of closed depressions from 1/3 arc-second (approximately 10 m resolution) National Elevation Dataset (NED) were run on the U.S. Geological Survey (USGS) “Yeti” high-performance computing cluster. The full NED was first conditioned to reduce the creation of artificial closed depressions by breaching digital dams at road and stream crossings, using the flowlines and transportation route vectors from the USGS National Map. The resulting depressions were selected according to location within geologic units having the potential for karst, and screened for occurrence in areas of developed land, open water and wetlands, and areas of glacial and alluvial sediment cover. The results were used as the input to create a nationwide depression density map. Our results were compared with karst depression density maps for diverse karst regions within states that have existing closed depression inventories. The individual state-scale maps compared favorably to the results obtained from the method applied universally across the nation and illustrated regional sinkhole hotspots in known areas of well-developed karst. Limitations of the automated method includes false positive depressions resulting from artifacts generated during the computer processing of the elevation models, and inclusion of depressions resulting from non-karst geomorphic processes. Although concerted efforts were made to validate the depression polygons as actual karst features, a more thorough examination of each of the resulting depressions is required on an individual basis to determine its validity as a true karst or pseudokarst landform.

Data sets of actual evapotranspiration rates from 2000 to 2017 for basins in Florida and parts of Alabama and Georgia, calculated using the water-balance method, the bias-corrected Operational Simplified Surface Energy Balance (SSEBop) model, and the land-use crop coefficients model

Annual actual evapotranspiration (ETa) rates in 55 basins in Florida and parts of Alabama and Georgia were evaluated for 2000–17 using the Operational Simplified Surface Energy Balance (SSEBop) model at about a one-square kilometer resolution (Sepúlveda, 2021). SSEBop ETa rates were bias corrected on the basis of ETa rates computed from weather observations at 24 micrometeorological evapotranspiration flux (MEF) stations, stratified by land-use type and referred to as mETa rates. Uncorrected and bias-corrected SSEBop ETa rates were evaluated by comparison with independent estimates based on a crop-coefficient method for generalized land-use types (luETa) and a water-balance method for each basin (wbETa). Average annual estimates of SSEBop ETa (uncorrected and bias-corrected) and differences (residuals) from average annual estimates based on luETa rates and wbETa rates for each of the 55 basins are provided by each of the five Florida Water Management Districts and by the Tampa Bay Water regional utility.

Data release for Evidence of glacial activity during MIS 4 in the Rocky Mountains, Colorado, USA

The Ziegler Reservoir fossil site near Snowmass Village, Colorado (USA) provides a rare opportunity to examine environmental conditions in the Rocky Mountains during marine isotope stage (MIS) 4 (71–57 ka). Although recognized as a global-scale cold event, MIS 4 is typically absent from Rocky Mountain glacial chronologies because the geologic evidence was either covered or destroyed during the subsequent, and larger, MIS 2 (Pinedale; 29–14 ka) glaciation. The Ziegler Reservoir site is perched on a ridge above Pinedale glacial limits, which allowed for the preservation of a long-lived sequence of predominantly eolian sediments that spans from late MIS 6 (ca. 140 ka) through early MIS 3 (ca. 55 ka). Sediments dating to MIS 4 exhibit a significant increase in clay-sized particles, which suggests the source areas were enriched with fine-grained material at that time. We hypothesize that this increase in clay content is the result of rock-flour production by nearby valley glaciers that were active in the Rocky Mountains during MIS 4. If correct, our study illustrates how recognizing indirect evidence of glacial activity can result in a more complete record of past climate conditions than what could be achieved by the study of glacial moraines alone.

Río Icacos, Puerto Rico, Turbidity, FDOM, and Water Temperature, March 2017 to March 2019

The dataset presents 5- or 15-minute data for turbidity and Fluorescent Dissolved Organic Matter (FDOM) measured by in-stream sensors at the USGS gage Río Icacos near Naguabo (50075000), Luquillo Experimental Forest, Puerto Rico. The measurement period was 10 March, 2017 to 1 March, 2019. The USGS sensors were co-located with sensors for nitrate and specific conductance operated by University of New Hampshire (UNH), and these datasets are all used in the accompanying publication. A 4-month gap in turbidity in 2018 was mostly filled by UNH data, using a relation between USGS turbidity and co-located UNH turbidity when both sensors were operating. The main metric used in the journal paper was the ratio of coefficient of variation (CV) of concentration (of FDOM, turbidity, nitrate, and specific conductance) to CV of stream discharge over a moving 30-day window, and the main analysis was how this ratio responded to variations in climatic forcing.
