Lake Erie Fish Community Data, 2013-2019 Lake Erie Fish Community Data, 2013-2019
Assessing the distribution and abundance of both predator and prey (forage) fish species is a cornerstone of ecosystem-based fishery management, and supports decision making that considers food-web interactions. In support of binational Great Lakes fishery management the objectives of this survey were to: provide estimates of densities of key forage and predator species in the western...

Lake Michigan Sea Duck Survey 2009-2014 Lake Michigan Sea Duck Survey 2009-2014
These data contain observation and null polygons for waterfowl aerial surveys of Lake Michigan collected through the years 2009-2014. Polygons were created adjacent to either side of the flight lines (transects). The right and left offset of the polygons from the flight path, was determined using the average altitude of the plane along the transect and the observation angle through the...
Lake Ontario April Prey Fish Bottom Trawl Survey, 1997-2021 Lake Ontario April Prey Fish Bottom Trawl Survey, 1997-2021
This data release includes Lake Ontario prey fish data including species captured, relative abundance, spatial distribution, size structure, and age data from the April or spring prey fish bottom trawl survey, 1997 and 2021. Data from 1997 - 2015 are from U.S. waters of Lake Ontario while data from 2016 - 2021 include both U.S. and Canadian waters of Lake Ontario. Details about the...
Lake Ontario Water Quality and Velocity Transect Data 2015-18 Lake Ontario Water Quality and Velocity Transect Data 2015-18
From May of 2015 through September of 2018, water-quality were collected at 178 locations and velocity data were collected along 7 transects from select tributaries, embayments, and nearshore lake locations along New York's Lake Ontario waterfront in support of the Great Lakes Restoration Initiative and the Lakewide Action Management Plan. These data include: depth, velocity magnitude...
LAMP assay for detection of Asian fish tapeworm LAMP assay for detection of Asian fish tapeworm
Data are relative fluorescent units obtained from the FAM channel of a AmpliFire Isothermal Fluorometer (Agdia, Inc., Elkhart, USA) recorded every 10 sec during as isothermal (LAMP) amplification. The isothermal reaction is to detect the Asian fish tapeworm, Schyzocotyle acheilognathi [syn. Bothriocephalus]. Samples (column headers) are described in tabs and include 1) positive control...
Lampropeltis californiae (California Kingsnake) behavior, male combat video, Apache Junction, AZ Lampropeltis californiae (California Kingsnake) behavior, male combat video, Apache Junction, AZ
These data represent the interaction between two male individuals of California Kingsnakes in Apache Junction, northern Pinal County, Arizona. The interaction was observed, recorded on video, and documented. The dataset is a time series description of the interaction and behaviors of two male California Kingsnakes (Lampropeltis californiae; the two individuals are labeled "B" and "D" for...
Lanai Island Spatial Prioritization of Native Plant Habitat and Hunting Areas, 2021 Lanai Island Spatial Prioritization of Native Plant Habitat and Hunting Areas, 2021
This data release includes data and metadata on all native plant species, native habitat, and hunting areas included in the spatial prioritization analyses. Broadly, recovery of threatened and endangered species requires specific management actions by natural resource managers at a fine scale. We used a systematic conservation planning framework to outline conservation goals across...
Land Change Monitoring, Assessment, and Projection (LCMAP) Collection 1.1 Annual Land Cover and Land Cover Change Validation Tables (1985-2018) for the Conterminous United States Land Change Monitoring, Assessment, and Projection (LCMAP) Collection 1.1 Annual Land Cover and Land Cover Change Validation Tables (1985-2018) for the Conterminous United States
A validation assessment of Land Cover Monitoring, Assessment, and Projection Collection 1.1 annual land cover products (1985-2019) for the Conterminous United States was conducted with an independently collected reference data set. Reference data land cover attributes were assigned by trained interpreters for each year of the time series (1984-2018) to a reference sample of 24,971...
Land Change Monitoring, Assessment, and Projection Collection 1.1 Science Products Land Change Monitoring, Assessment, and Projection Collection 1.1 Science Products
LCMAP Science Products are developed by applying time-series modeling to U.S. Landsat Analysis Ready Data (ARD) to detect land surface change. An application of the Continuous Change Detection and Classification (CCDC, Zhu and Woodcock 2014) was developed by the LCMAP Science Team at the USGS Earth Resources Observation and Science (EROS) Center (Brown et al., 2020). LCMAP Collection v1...
Land Cover Assignments of 300 locations in the Pacific Northwest in 2000 Land Cover Assignments of 300 locations in the Pacific Northwest in 2000
Area estimates of land cover and land cover change are often based on reference class labels determined by analysts interpreting satellite imagery and aerial photography. Different interpreters may assign different reference class labels to the same sample unit. This dataset include land cover attributes for the year 2000 assigned by 7 image analysts, working independently of each other...
Land Cover Basin Characteristics Rasters for South Carolina StreamStats 2021 Land Cover Basin Characteristics Rasters for South Carolina StreamStats 2021
In cooperation with the South Carolina Department of Transportation, the U.S. Geological Survey calculated four land cover basin characteristics rasters as part of preparing the South Carolina StreamStats 2021 application. These datasets are raster representations of impervious surface, developed, forested, and storage land cover attributes within the South Carolina StreamStats 2021...
