Data

This dataset includes larval fish catches, species identifications, total length measurements, and relevant covariate data from a larval fish community survey of the U.S. waters of Lake Ontario. Sites were surveyed along a bottom depth gradient of 5 to 225 meters, covering a range of nearshore and offshore habitat between the months of May and July 2024. Vessel and gear descriptions are...

This dataset contains Mysis count and length measurements from vertical whole-column net tows along a depth gradient in Lake Ontario and associated operation data. Sample dates occurred during August 2021 and June, July, and August 2022. Site depths ranged from 70 to 202 meters bottom depth. Sites were sampled using a paired day-night sampling approach. At each visit, the net was lowered...

This data set contains Lake Trout (Salvelinus namaycush) egg density estimates obtained from suction sampling across five locations in Lake Ontario. These data were collected in October-November 2020 and November-December 2024 as part of an effort to identify Lake Trout spawning locations and habitat preference in Lake Ontario. Additional information on habitat characteristics at each...

This data set contains Lake Trout (Salvelinus namaycush) egg catch per unit effort (CPUE) estimates obtained from egg traps set on Stony Island Reef in Lake Ontario. These data were collected from sampling efforts in November 2017 and October-November 2019. Stony Island Reef is a cobble spawning reef located in the eastern basin of Lake Ontario and was chosen as the study site because it...

The U.S. Geological Survey measured lakebed and lake-water temperatures to identify areas of groundwater discharge (inflow to the lake) and recharge (outflow from the lake) at Moody Pond, a groundwater flow-through lake, in Mashpee, Massachusetts. The relative temperatures of lakebed sediment and lake water are indicators of the water flux direction across the lake bottom. Lakebed and...

The land application of drill fluids is governed by rules established in the Oklahoma Administrative Rules (165:10-7) and permitted by the Oklahoma Corporation Commission (OCC). While data on the volume and location of land application is publicly accessible through the OCC's website, much of the information is in scanned form documents which limits the operability of these data. This...

This carbon dataset is generated from the parallel Integrated Biosphere Simulator (pIBIS). Annual carbon variables cover 1985-2020 at 1-km (990m) spatial resolution. All the variables are in NetCDF format. Each variable has 36 layers, 2960 rows, 4677 columns, and in WGS_1984_Albers projection. A single layer mask file TIF is provided. Carbon stock and flux units are in kgC/m2 and kgC/m2...

Home Owners’ Loan Corporation (HOLC) maps illustrated patterns of segregation in United States cites in the 1930s. As the causes and drivers of demographic and land use segregation vary over years, these maps provide an important spatial lens in determining how patterns of segregation spatially and temporally developed during the course of the past century. Using a high-resolution land...

The LANDFIRE (LF) 2001 (version 1.0.5) Refresh of the LF National Base Map enhanced the layers of the LF National data set to provide a foundation upon which to build an updated geospatial data set. The enhancements were developed to facilitate comparative analyses, evaluate trends, and potentially monitor changes over time. In particular, LF 2001 enhancements addressed: incomplete data...

The U.S. Geological Survey (USGS) provides Level-2 Provisional Aquatic Reflectance (AR) Products through EROS Science Processing Architecture (ESPA) On-Demand Interface for the Collection 2 Landsat 8-9 archive. This dataset includes n=742 provisional AR products for the visible and near-infrared (VNIR) bands for the Operational Land Imager (OLI) sensor at 30 meters resolution coincident...

The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, SD has developed a cloud validation dataset from Collection 2 images throughout the history of Landsat. Two North American locations with high overlap between WRS-1 and WRS-2 were chosen. For each location, 20 images were selected at random from the Landsat archive, with at least one...

Remote sensing-based evapotranspiration (ET) can be derived using various methods, from soil moisture accounting to vegetation-index based approaches to simple and complex surface energy balance techniques. Due to the complexity of fully representing and parameterizing ET sub-processes, different models tend to diverge in their estimations. However, most models appear to provide...
