Assessment of geochemical cycling within tidal wetlands and measurement of fluxes of dissolved and particulate constituents between wetlands and coastal water bodies are critical to evaluating ecosystem function, service, and status. The U.S. Geological Survey and collaborators collected surface water and porewater geochemical data from a tidal wetland located on the eastern shore of Sage Lot Pond in Mashpee, Massachusetts, within the Waquoit Bay National Estuarine Research Reserve, between 2012 and 2019. Additional porewater geochemical and field data from a tidal wetland on the eastern shore of Great Pond in East Falmouth, MA are also included. These data can be used to evaluate biogeochemical conditions and cycling...

Note: this dataset has been superseded by this new data product: Simpson, A., Turner, R., Blake, R., Liebhold, A., and Dorado, M., 2021, United States Register of Introduced and Invasive Species: U.S. Geological Survey data release, https://doi.org/10.5066/P95XL09Q. Invasive species are a subset of non-native (or nonindigenous) species, and knowing what species are non-native to a region is a first step to managing invasive species. This is the second update to the dataset "First comprehensive list of non-native species established in three major regions of the United States" supporting a USGS Open File Report by the same name published on 2018-10-17. Version 3.0 of the non-native species list, as of 2020-09-15,...

Lake-bottom sediment and associated quality-control samples were collected in August 2020 from one coring location (U.S. Geological Survey station 413756070321301, ASHUMET POND, MASHPEE MI-ASHPD-0011) in Ashumet Pond downgradient from a former fire-training area on Cape Cod, Massachusetts. The core was collected to determine if per- and polyfluoroalkyl substances (PFAS) were present in the bottom sediments of a lake known to have elevated concentrations of PFAS in surface water and groundwater (Tokranov and others, 2021), and whether the sediments could act as a continuous source of PFAS to the lake. Processing the sediment core entailed collection of discrete samples at intervals ranging from 1-5 centimeters (cm)...

Recent concern for the adverse effects from neonicotinoid insecticides has centered on risk for insect pollinators in general and bees specifically. However, natural resource managers are also concerned about the risk of neonicotinoids to conservation efforts for the monarch butterfly (Danaus plexippus) and need a tool to estimate risk for wild monarch butterflies exposed to clothianidin. In the present study, monarch butterfly larvae were exposed to contaminated milkweed plants from hatch until pupation, and the effects upon larval survival, larval growth, pupation success, and adult mass were measured. Soils dosed with a granular insecticide product lead to average clothianidin concentrations of 10.8 - 843 ng/g...

This dataset reports select histopathological changes in liver, kidney, gonad, spleen, brain, heart, skeletal muscle, lung, or adrenal gland of zebra finches exposed to 15mg/kg, 18mg/kg, 30mg/kg, 60mg/kg, 75mg/kg, 125mg/kg, or 250mg/kg clothianidin (CTD) (with controls) by gavage, in water, or on millet seed either as a single dose or for 7 days. The goal of the project is to develop a subacute neonicotinoid toxicity model using zebra finches as a model passerine. We have completed two acute toxicity trials using CTD insecticide. Based on these studies, we estimate the no observable effect level (NOAEL) and the lowest observable effect level (LOAEL) for CTD in zebra finches to be 15 and 30 mg/kg body weight, respectively,...

This dataset consists of 262 variables which describe various known and suspected point and non-point sources of contaminants and endocrine disrupting compounds (EDCs) throughout the Chesapeake Bay Watershed. Contaminant data was summarized to the NHDPlus Version 2.1 catchment level (1:100K). Contaminant data summarized span a time range of 2001 to 2016 and include regulated facilities, pesticides, manure and biosolids application data, mercury deposition, animal feeding applications, septic systems, landfills, and land use and land cover. These data are presented in a comma separated file, which includes all variables summarized and the NHDPlus Version 2.1 FEATUREID field (also known as COMID). The FEATUREID field...

A data release containing information on macroinvertebrate communities and sediment toxicity in the Buffalo River Area of Concern (AOC) and reference areas immediately upstream of the AOC collected during 2017 and 2020. Macroinvertebrate community samples were collected using bottom-deployed multiplate artificial substrate samplers and organisms were identified to the lowest practical taxonomic resolution and used to calculate metrics of biological integrity following standard New York State Department of Environmental Conservation procedures. Bed sediments were collected using a petite Ponar dredge and used for toxicity tests with two test species, Chironomus dilutus and Hyalella azteca, following USEPA test methods...

The U.S. Geological Survey Toxic Substances Hydrology Program Cape Cod Research site has been the subject of intensive hydrological and geochemical investigations. The site has multiple sources of poly- and perfluoroalkyl substances (PFASs), including perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA), for which the U.S. Environmental Protection Agency has issued health advisories because of potential adverse human health effects. During 2014 and 2015, groundwater contamination by PFASs from a fire-training area and a wastewater treatment facility effluent infiltration beds, located on Joint Base Cape Cod, was assessed by collecting groundwater samples and sediment cores (Figures 1 and 2). The water...

Data were collected as part of a study to identify sources of E. coli contamination at several beaches located in the Grand Calumet River Areas of Concern, located in northern Indiana on Lake Michigan, as well as in Illinois and Wisconsin on Lake Michigan. Water samples were collected at each site in Indiana three times a week for thirteen weeks and at each site in Illinois and Wisconsin. All samples were analyzed for E. coli bacteria (an indicator bacteria for fecal contamination) and species-specific molecular markers (microbial source tracking, MST), including human, gull, and dog. Presence of MST markers indicates a fecal source at that location associated with the target animal. Field conditions were recorded...

Riparian ecosystems are valuable to the ecological and human communities that depend on them. Over the past century, they have been subject to shifting management practices to maximize human use and ecosystem services, creating a complex relationship between water policy, management, and the natural ecosystem. This has necessitated research on the spatial and temporal dynamics of riparian vegetation change. The San Acacia Reach of the Middle Rio Grande has experienced multiple management and river flow fluctuations, resulting in threats to its riparian and aquatic ecosystems. This research uses remote sensing data, GIS, a review of management decisions, and an assessment of climate to both quantify how riparian...
