Northatlantic Connect the Connecticut by abstract, last updated: Jul 10, 2020 02:50 PM: Connect the Connecticut is a collaborative effort to identify shared priorities for conserving the Connecticut River Watershed for future generations, considering the value of fish and wildlife species and the natural ecosystems they inhabit.

Salinity, Northeast U.S. by abstract, last updated: Jul 10, 2020 02:50 PM: The presence of salt water is an important determinant of ecological communities. This dataset modifies the Northeast Terrestrial Habitat Map developed by The Nature Conservancy to denote the presence of salt water or brackish water as follows: -Wetlands and waters classified by the National Wetland Inventory (http://www.fws.gov/wetlands/) as "marine", plus additional ocean waters to a distance from the coast of 10 km, are considered salt water and assigned a value of "1" -Wetlands and waters classified by the National Wetland Inventory as "upper estuarine" are considered oligohaline and assigned a value of "0.5" -Wetlands and waters classified by the National Wetland Inventory as "estuarine" are considered brackish and assigned a value of "0.7" -All other areas, both terrestrial and aquatic, are assigned a value of "0"

Marine Bird Mapping and Assessment by abstract, last updated: Jul 10, 2020 02:50 PM: This project is a collection of data, the download includes: the annual probability of observing one individual, the annual probability of encountering a large flock, and the monthly probability of observing one individual, for the full set of 24 marine bird species (in .csv format), and the associated report “Mapping the distribution, abundance and risk assessment of marine birds in the Northwest Atlantic.” NOTE* The Data Basin link takes you to the "Coastal and Marine" gallery, see the "Marine Bird Assessment" folder to view the species data.

Average November-March Snow Depth (mm), Northeast by abstract, last updated: Jul 10, 2020 02:50 PM: This dataset represents a 5 year average, November to March 2007/2008 - 2011/2012, snow depth in millimeters. This data set contains output from the NOAA National Weather Service's National Operational Hydrologic Remote Sensing Center (NOHRSC) SNOw Data Assimilation System (SNODAS). SNODAS is a modeling and data assimilation system developed by NOHRSC to provide the best possible estimates of snow cover and associated parameters to support hydrologic modeling and analysis. The aim of SNODAS is to provide a physically consistent framework to integrate snow data from satellite, airborne platforms, and ground stations with model estimates of snow cover (Carroll et al. 2001). SNODAS includes procedures to ingest and downscale output from the Numerical Weather Prediction (NWP) models, and to simulate snowcover using a physically based, spatially-distributed energy- and mass-balance snow model. SNODAS also includes procedures to assimilate satellite-derived, airborne, and ground-based observations of snow covered area and Snow Water Equivalent (SWE).

Hydrography High Resolution, 1:24,000, Northeast by abstract, last updated: Jul 10, 2020 02:50 PM: Hydrography represents stream centerlines and off centerlines with greater than 30 hectare flow accumulation for the Northeast region. The purpose of this dataset is to improve the National Hydrography Dataset (NHD) for the Northeast region. The NHD is a national framework for assigning reach addresses to water-related entities, such as industrial discharges, drinking water supplies, fish habitat areas, wild and scenic rivers. Once linked by reach addresses, the upstream/downstream relationships of these water-related entities can be analyzed.

Large Woody Debris Habitat Improvement in tribs to North Sylamore Creek (AR) by admin, last updated: Jul 10, 2020 02:44 PM: This project will improve the habitat in tributaries leading to North Sylamore Creek (Arkansas) through the addition of large woody debris.

Stream Bank & Riparian Restoration along the Wild and Scenic Cossatot River on the Ouachita NF by admin, last updated: Jul 10, 2020 02:44 PM: Six riparian sites have severe erosion from loss of riparian vegetation and heavy recreational use. Riparian habitat function will be restored by stabilizing stream banks and planting vegetation. Stream habitat cover will increase with addition of materials to repair stream banks. Campsites will be designated and hardened. To measure effectiveness, water samples taken every 3 months over the past 4 years will continue for at least the next 4 years by the Cossatot River Watch Stream Team to compare pre- and post-restoration.

Restoration of a backwater of the Arkansas River, Rector Chute by admin, last updated: Jul 10, 2020 02:44 PM: The Rector Chute backwater will be restored to prevent conversion of aquatic habitat to terrestrial habitat through sedimentation. Select areas will be dredged with a Mudcat hydraulic dredge.

North Peninsula State Park Saltmarsh Restoration by admin, last updated: Jul 10, 2020 02:44 PM: This project will create a healthy, productive saltmarsh habitat (9 acres, including complete restoration of 2 acres of historical marsh habitat filled with spoil as a result of dredge activities and enhancement of 7 acres of saltmarsh) in North Peninsula State Park, Volusia County, Florida.

Ulele Springs Restoration Project by admin, last updated: Jul 10, 2020 02:44 PM: This project, run by the Ecosphere Restoration Institute, Inc, will create a natural spring and restore native wetland vegetation within the state of Florida.

Improving Management of Seagrass Resources through Restoration and Assessment by admin, last updated: Jul 10, 2020 02:44 PM: Lead by the Environmental Protection Commission of Hillsborough City, this project will manage seagrass beds through creating a poll n troll zone to reduce seabed scaring, as well as testing different grass restore methods.
