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...

The Stream Conditions of Chester County Biological Monitoring Network was established by the U.S. Geological Survey and the Chester County Water Resources Authority in 1969. Benthic-macroinvertebrate, habitat, and stream chemistry data were collected annually from 1998-2021 at 18 fixed location sites. Additionally, nine flexible location sites were selected and sampled annually from 1998-2021. Some of the flexible location sites were sampled more than once over the study period. All data were collected in the fall months (October-November) during baseflow conditions. The benthic-macroinvertebrate data collected was used to calculate six metrics and to establish an index of biotic integrity for each sample, while...
This dataset contains taxonomic information, counts, and lengths of macroinvertebrates collected from rivers in northwest Alaska using drift and kick nets during summer and fall 2015-2019.

The USGS and Virginia Tech are determining if and how the implementation of conservation practices, such as best management practices (BMPs), in watersheds have improved the health of Chesapeake nontidal streams. Our goal is to identify the effects of BMPs and land-use on stream ecosystems by linking upstream landscape change to stream physical habitat, water quality, flow and temperature, and macroinvertebrate and fish responses. We are also determining the specific sources of stress to streams and fish populations to help identify which management practices are most likely to improve stream health. Each year from 2021 to 2024 we study a different Chesapeake landscape setting that is a focus area for stakeholders...
Data represent physical (water quality, water nutrient analysis) and biological (fish, macroinvertebrate, and vegetation community) collections from the Shiawassee National Wildlife Refuge in Saginaw, MI, USA (specifically, historical management unit "Pool 1A" and the North and South management units of the Maankiki Marsh Complex.) The North and South management units of the Maankiki Marsh Complex were reconnected to the Shiawassee River in 2018, whereas Pool 1A represents a historically reconnected wetland. Additional sites within the Shiawassee River and Spaulding Drain (east of Pool 1A) were also sampled to represent parameters collected from the parent water system. All data were collected in 2019.
These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and describe bivalve count and size sampling and observations conducted at intertidal soft-sediment sampling sites in the northern Gulf of Alaska. This dataset consists of five comma separated files (.csv): 1) bivalve taxonomy table, 2) bivalve sampling site table, 3) bivalve count table, 4) bivalve size table, and 5) list of Gulf Watch Alaska principal investigators and collaborators.
These data describe observations of sea otter foraging behavior in Glacier Bay National Park and Preserve. Data consist of dive and surface times, success in prey retrieval, prey item, prey quantity, and size. Additionally, location of observations, and age class, sex, and pup status of the focal sea otter were also recorded.
This data release supports the manuscript entitled "Multiple approaches to surface water quality assessment provide insight for small streams experiencing oil and natural gas development" (DOI )and includes two data sets: 1) Mean daily discharge, temperature, and conductivity data from three stream sites in the Wyoming Range for summers 2012-2016; 2) Suspended sediment and macroinvertebrate metrics for 40 stream sites in the Wyoming Range for August 2016.
These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program, nearshore monitoring component. The dataset is comprised of six comma separated values (.csv) file exported from a relational database. The data consist of: 1) transect summary, 2) nest details, 3) egg float and stage data, 4) chicks diets, 5) chick diet taxonomy, and 6) Gulf Watch Alaska contributors.
The objective of this study was to determine why certain stream insects tend to be found in certain temperature ranges. Many federal, state and local agencies use stream insects to monitor the health of freshwater ecosystems. While the temperature ranges for some insects are often inferred from the temperature of the waters where they were collected, this inference is coarse at best and problematic at worst. Stream temperatures fluctuate a lot during the year and temperature may or may not control where an insect lives. Field insects were collected and sent to a laboratory for testing several temperature endpoints, particularly at higher temperatures. Respiration, breathing rate, and some physical activities were...

These data are part of the Gulf Watch Alaska (GWA) long-term monitoring program and describe mussel sampling and observations conducted in the northern Gulf of Alaska. This dataset consists of six comma separated files (.csv): 1) mussel sampling site layout information, 2) mussel counts for mussels greater than 20 millimeters in a quadrat, 3) mussel size measurements for mussels greater than 20 millimeters in a quadrat, 4) mussel counts for all mussels collected from core samples, 5) mussel size frequencies for all mussels collected from core samples, and 6) list of Gulf Watch Alaska principal investigators and collaborators.
A data release containing information on macroinvertebrate communities and sediment toxicity in the Niagara River and adjacent areas collected during a sampling effort conducted between 2019 and 2020, and a sampling effort conducted in 2022. During the first sampling effort, bed sediments were collected at 60 sites in the Niagara River, 5 sites on lower Smoke Creek, and 6 sites on Hoyt Lake for use in sediment toxicity testing and determination of grain size distribution and total organic carbon concentration. Additionally, macroinvertebrate samples were collected from the 60 sites on the Niagara River. During the second sampling effort, bed sediments were collected at 10 sites on lower Smoke Creek (5 of which were...

The current Adirondack Long-Term Monitoring Program combines monitoring of streams and soils based on a watershed design. Not only are headwater streams an important component of Adirondack ecosystems, they are closely tied to the terrestrial environment through runoff that is strongly influenced by soil and vegetation processes. This linkage makes headwater streams a useful tool for monitoring the overall condition of the watershed, and by combining stream and soil monitoring within watersheds, the response of Adirondack ecosystems to environmental disturbances such as acid rain and climate change can be better understood. For example, the unexpectedly slow reversal of stream acidification from decreased atmospheric...
In October 2017, the Atlas, Nuns, and Tubbs wildfires in Napa and Sonoma Counties, CA burned approximately 133 thousand acres. Multiple watersheds were affected by the fires, with up to 95% of some watersheds being burned. Post-fire assessments were conducted at 10 sites within Napa and Sonoma Counties to assess the effects of fire on sediment, water quality, and ecology. This data release contains data from the analysis of benthic macroinvertebrate samples, bed sediment samples, water quality samples, and algal samples.
Note: this data release is currently being revised and is temporarily unavailable. Sampling is conducted by the U.S. Geological Survey (USGS) at nine wells, eight surface water sites, three bed sediment retention ponds, and two fields for soil samples at areas near and within the Open Burning/Open Detonation (OB/OD) areas in the Ammunition Area (AA) of Letterkenny Army Depot. Analytical results for groundwater samples collected from 2018-2021 are provided in “OBOD_wells_data_2018-2021.xlsx”. Analytical results for surface-water samples from 2018-2021 are provided in “OBOD_sw_data_2018-2021.xlsx”. Benthic macroinvertebrate taxonomic data collected from 2018-2021 at three streams are provided in “OBOD_benthic_taxa_2018-2021.xlsx”....
