This Event Duration Monitoring dataset relates to overflow performance in England and Wales. Water and Sewerage Companies (WaSCs) submit this regulatory return annually to the Environment Agency or Natural Resources Wales to meet discharge conditions outlined in the Environmental Permitting Regulations.The English data were downloaded from environment.data.gov.uk (accessed 27th March 2025). Sewer Storm Overflow EDM Annual Returns Data for Wales were downloaded from the Dŵr Cymru/ Welsh Water and Hafren Dyfrdwy websites.For England, the dataset also includes reasons why event duration monitors may have provided information for <90% of the relevant return period, and why an overflow may have high spill counts in that period. What doesn't this dataset show?There are a significant but unknown number of overflows which are not included in this dataset because the WASCs and the Environment Agency don't know where they are within the sewer network. If you spot signs of sewage pollution please report this to the Environment Agency on 0800 80 70 60 or Natural Resources Wales on 0300 065 3000 so that these unmapped discharges can be pinpointed.Emergency overflows in England and Wales are not included in this dataset as the Environment Agency and Natural Resources Wales only require storm overflows to be included in the EDM returns, though some WASCs do record this information. Emergency overflows do have permits but these are for use in the event of mechanical issues, for example pump failure. We do publish the emergency overflows for England and Wales in the consented discharges dataset, but we don't have spill duration data for them. You can find out more about environmental permits for storm and emergency overflows for England here and Wales here.Quality ControlThe Rivers Trust has endeavoured to clean, check and interpret the data, but cannot be held responsible for any missing or inaccurate data. Points in the sea may be long-sea outfalls or they may be errors in the data. Water companies, citizen scientists and map users are welcome to contact us to notify any known data errors on specific overflows and we will flag these in the map popups and pass on to the regulators. We are providing feedback to the Defra storm overflows taskforce about how to improve transparency around sewer storm overflows, and would welcome feedback and suggestions.Contact us at data@theriverstrust.org

NOAA's Electronic Navigational Charts (NOAA ENCs) have been developed to support the marine transportation infrastructure and coastal management. The NOAA ENCs are in S-57, a data standard developed by the International Hydrographic Organization (IHO) to be used for the exchange of digital hydrographic data. NOAA ENCs can be used in Geographic Information Systems, (GIS) allowing for broader public access. Many GIS's, however cannot read an ENC's native S-57 format to address this problem. NOAA's ENC Direct to GIS web portal provides comprehensive access to display, query, and download all available large scale NOAA ENC data in a variety of GIS/CAD formats for non-navigational purposes using Internet mapping service technology. Nautical chart features contained within an NOAA ENC provide a detailed representation of the U.S. coastal and marine environment. This data includes coastal topography, bathymetry, landmarks, geographic place names and marine boundaries. Features in an NOAA ENC are limited in that they only represent the geographic region that is depicted in that particular NOAA ENC. By aggregating nautical features from all NOAA ENCs in the creation of GIS data, a contiguous depiction of the U.S coastal and marine environment is achieved.

Environmental Sensitivity Index (ESI) maps are an integral component in oil-spill contingency planning and assessment. They serve as a source of information in the event of an oil spill incident. ESI maps are a product of the Hazardous Materials Response Division of the Office of Response and Restoration (OR&R).ESI maps contain three types of information: shoreline habitats (classified according to their sensitivity to oiling), human-use resources, and sensitive biological resources. Most often, this information is plotted on 7.5 minute USGS quadrangles, although in Alaska, USGS topographic maps at scales of 1:63,360 and 1:250,000 are used, and in other atlases, NOAA charts have been used as the base map. Collections of these maps, grouped by state or a logical geographic area, are published as ESI atlases. Digital data have been published for most of the U.S. shoreline, including Alaska, Hawaii and Puerto Rico.

Ichthyoplankton (larval fish) surveys are a component of the U.S Fish and Wildlife Services (USFWS) Lower Great Lakes Fish and Wildlife Conservation Office (LGLFWCO) Aquatic Invasive Species (AIS) Early Detection and Monitoring (EDM) program. Larval fish surveys were included in the EDM program starting in 2014 with the hopes of increasing AIS detections by focusing on sampling the most abundant life-stage of fishes. Surveys occurred annually from 2014 - present, excluding 2020 due to COVID-19 restrictions which prevented sampling for that year. Sampling focuses on harbors and rivers of the lower Great Lakes (Erie and Ontario) as determined by a risk-based prioritization framework for AIS in the Great Lakes.Samples are collected using larval seine nets (500 µm) and plankton nets (500 µm) that are towed from the stern or pushed from the bow of a vessel for a short duration (usually 5 minutes). At one point, light traps were also used but are no longer apart of the current sampling gear suite. Samples are preserved using 95% ethanol (EtOH) which allows for tissue and DNA preservation. Samples are processed for fish identification in a few different ways: ethanol decant, tissue homogenate and taxonomically. Ethanol decant and tissue homogenizing are genetic identification methods that are provided by the Northeast Fishery Center (NEFC). Taxonomic identifications are conducted in-house (LGLFWCO) using available keys for larval fishes of the Great Lakes region. Recently, ethanol decants have been the primary method of identification due the efficiency of sample processing.The information within this dataset is geospatial in nature and documents larval fish sampling events. Both abiotic and biotic data is collected for each individual sampling event. Taxonomic and genetic identifications of eggs and larvae are to the lowest possible taxa. Genetic identification results only represent presence/absence of a species detection. Taxonomic identification results could include the number of species in the sample. Although infrequent, some early stage juvenile fish are represented in this data set. This data set contains survey information from 2017 - present (excluding 2020). Although collections began in 2014, the early years of implementation resulted in inconsistencies requiring their exclusion here.

These data represent Seasonal Mangagement Area locations where regulations implement speed restrictions in shipping areas at certain times of the year along the coast of the U.S. Atlantic seaboard.

This dataset was aquired under FOI requests submitted to water companies in England by The Guardian. It shows spill frequency and duration for CSOs which have Event Duration Monitoring (EDM) equipment installed. The data were matched to the Environment Agency's consented discharge database to obtain the grid reference locations of the discharges in order to provide recreational river users and those coming in to contact with river water, the best available spatial information on health risks.N.B. Thames Water data were provided as separate discharges rather than categorised spills as per the EA's Spill Count Method and are therefore not directly comparable to other water companies. 2019 data from Northumbrian Water Ltd. were not provided in a format which could be mapped, so we have substituted the 2018 data acquired by an FOI request to the Environment Agency by Channel 4.

The Coral Reef Ecosystem Monitoring GIS data service provides access to data collected in the Mariana Archipelago by the Coral Reef Ecosystem Program of the Pacific Islands Fisheries Science Center. Included are a subset of the data collected and processed in the Marianas archipelago between 2000 and 2014.

The Hudson River Shallow Water Mapping project characterizes the bottom of the Hudson River Estuary in shallow water (<3 m). The characterization includes acoustic data and bottom verification through sediment cores and grabs. Sediment cores and grabs for the zone of the Hudson River between Troy, NY and Saugerties, NY were collected in April 2010 by scientists of Lamont-Doherty Earth Observatory operating as sub-contractors of Fugro Atlantic. Samples were collected using the D. Prichard, a Stony Brook University vessel and analysed and archived at Lamont Doherty. This data set describes details of the sediment grabs. The grab samples were described in the field.Original contact information: Contact Org: NOAA Office for Coastal Management Phone: 843-740-1202 Email: coastal.info@noaa.gov
