This database contains aquatic benthic macroinvertebrate abundance data derived from samples collected from 33 75-meter stream site locations within the Delaware Water Gap National Recreation area in September of 2006. The database contains two separate table files (i.e., entities) in csv format: 1) Macroinvertebrate site abundance data and 2) site location data. For macroinvertebrate data, six samples were collected within 2-3 riffle areas within each site location with Portable Invertebrate Box Samplers (0.1-m2 sample area, 350 micron mesh collecting nets). Where possible, organisms were identified to the genus taxonomic level using a stereoscope except for organisms of the family Chironomidae and class Oliogochaeta, which were mounted on slides and identified with compound microscopes. For each site, data from six samples compiled into a single site abundance value for each taxon. Site location data consists of UTM coordinates (NAD 1983, UTM zone 18N) for the 33 sample sites.

This data release contains ten data tables and a data dictionary for the Technical Assistance Agreement (TAA) between the U.S. Geological Survey and the San Francisco Estuary Institute titled "Lower San Francisco Bay Bivalve Grazing Rates”. The data are provided in comma-delimited value spreadsheets as well as Microsoft Excel Worksheet formats.

This dataset contains information on benthic invertebrate community structure of samples collected from nearshore index monitoring stations within a Great Lake basin each year. The composition of benthic invertebrates (such as insects, worms, mussels, snails and crayfish) found in a sample is used as a biological indicator of trophic status and general environmental conditions to help understand ecosystem function, structure and change. Surveys are typically conducted in one of the Great Lakes basins each year. In most cases, five replicate samples (600 μm mesh, 9-inch ponar) were collected at each station. This dataset links with Sediment chemistry (Great Lakes nearshore areas) and Water chemistry (Great Lakes nearshore areas) datasets.

This data release links benthic macroinvertebrate sites to both the NHDPlus Version 2 and NHDPlus High Resolution Region 02 networks, hereafter referred to as V2 and HR, using the hydrolink methodology. Linked benthic macroinvertebrate sites are those included in the Chesapeake Bay Basin-wide Index of Biotic Integrity (Chessie BIBI) developed by the Interstate Commission on the Potomac River Basin (ICPRB) and available from the Chesapeake Bay Program (https://datahub.chesapeakebay.net/LivingResources). The data set contains a unique sample identifier created by ICPRB, survey program, coordinates of sample, linked V2 COMID and HR Permanent Identifier, and information regarding uncertainty in the attribution. We strongly caution the use of sampling points with attribution uncertainty to avoid spurious attribution of geospatial data to benthic macroinvertebrate samples.

These data were used to describe temporal trends in fish and invertebrate communities in the Scientific Investigators Report: Evaluation and Review of Ecology-Focused Stream Studies to Support Cooperative Monitoring, Fountain Creek Basin, Colorado. This data release consists of invertebrate data collected between 1985 and 2022, fish data collected between 2003 and 2022, and the input and output files from the trend analyses.

Benthic macrofauna community data, measured water quality parameters, and benthic index calculations from Pensacola Bay, 2016-2017. This dataset is associated with the following publication: Paul, J., J. Nestlerode, and B. Jarvis. Evaluating the effectiveness of M-AMBI with other biotic indexes in a temperate estuary. MARINE POLLUTION BULLETIN. Elsevier Science Ltd, New York, NY, USA, 193: 10, (2023).

This dataset provides analysis results for recent status of and trends in 44 fish and 99 macroinvertebrate assemblages in the Chesapeake Bay watershed. For both biological datasets a multi-metric index, metric of assemblage sensitivity, functional feeding group metric and habitat preference metric was selected for analysis. Sites used to calculate trends required a minimum of 7 years of data. Status was calculated as a three-year average by averaging metric values for the most recent three years of data at each site and trends were calculated using generalized additive models (GAM) in the R package 'mgcv' for the full window of sample years at each site. Detailed data preparation information, analytical methods, and results are presented and discussed in the associated Scientific Investigative Report (https://doi.org/10.3133/sir20255072).

This data set contains sensitive biological resource data for submerged aquatic vegetation (SAV) in Lake Michigan. Vector polygons in this data set represent SAV. Species specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer. This data set comprises a portion of the ESI data for Lake Michigan. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.
