In this DARP/EA, the Trustees evaluate potential restoration projects that exhibit a sufficient relationship to the natural resources injured and would compensate the public for natural resource losses resulting from the Spill.

The NOAA CRP proposes to provide financial assistance for a habitat restoration activity known as the “McCoys Creek Restoration Construction - The Branches” (aka the Branches), through grant award NA23NMF4630085 to Groundwork Jacksonville (GWJax). NOAA, the lead federal agency under the National Environmental Policy Act (NEPA), prepared this Enviro ...

The gamma distribution function may be used as a model for many sets of data. The electronic computer program in the Formula Translator (FORTRAN) IV for this function here provides the analytic solution to a set of data, gives the probabilities of exceeding or not exceeding arbitrary amounts, and indicates the amounts exceeded or not exceeded for a ...

This supplemental programmatic environmental assessment (SPEA) implements the National Environmental Policy Act (NEPA) statute (42 U.S.C. §§ 4321 et seq.) and is being prepared using the National Oceanic and Atmospheric Administration’s (NOAA) Policy and Procedures for Compliance with NEPA and Related Authorities as guidance.

As described in more detail in Section 4.1, the purposes of this action are to consider modifications to summer flounder commercial minimum mesh exemption programs, including: Consider revisions to the area associated with the Small Mesh Exemption Program (SMEP). This action will consider modifications to the area associated with the SMEP for summe ...

The purpose of this action is to implement 2026-2027 catch and landings limits for the commercial and recreational fisheries for summer flounder, scup, and black sea bass based on the best scientific information available as recommended by the Mid-Atlantic Fishery Management Council's (Council’s) Scientific and Statistical Committee (SSC). This act ...

This document describes methods for diagnosing non-prognostic variables from explicit prognostic variables from hourly updated NOAA models from 2020 onward. A previous diagnostics technical memorandum (Benjamin et al. 2021a) described diagnostics for earlier versions of the hourly updated models. Here, we describe diagnostics applicable to the High ...

Coastal communities are at risk from numerous environmental hazards including storms, flooding, erosion, and wildfire. Some areas are more at-risk than others due to a variety of factors. The National Centers for Coastal Ocean Science partnered with the Sunrise County Economic Council and other local partners to assess community risk in relation to ...

This report reviews the performance of the latest WMM and WMMHR, released in December 2024 and referred to as WMM2025 and WMMHR2025. It also verifies that they continue to meet specification MIL-PRF-89500B (U.S. Department of Defense, 2019) as of January 1, 2026 (hereafter 2026.0; the same convention applies to other years), and provides an assessm ...

This document summarizes existing information on the effects of fishing activities on benthic marine habitats. It was prepared by the National Marine Fisheries Service (NMFS) Office of Habitat Conservation with the intent of providing the Fishery Management Councils (Councils) with a reference document to assist in assessing adverse effects of fish ...

This document overviews the current state of the MYNN-EDMF, including the eddy diffusivity, mass flux (both up- and down-drafts), subgrid cloud representation, numerical procedures, the interactions/coupling between subcomponents, aspects of the practical tuning required for general operational use, the coupling to other physical parameterizations ...

Remote sensing measurements collected during snowfall events observed in the East River Basin of the headwaters of the Gunnison River are used to investigate statistical interrelations among such parameters of the water cycle as the snowfall accumulation/intensity, vertically integrated amounts of supercooled cloud liquid and ice, expressed as liqu ...

This document was developed in response to a growing regional interest to better understand how drought, especially flash drought, affects the Southeastern United States, and how the region can more effectively monitor, communicate, and respond to evolving conditions. The 2019 flash drought exposed critical gaps in early warning and monitoring syst ...

Biological invasions are an increasingly major global threat to the functioning of ecosystems today (Levine, 2008; Roy et al., 2024). While most non-native species have neutral or benign impacts, smaller subsets can cause significant ecological and economic harm (Levine, 2008). They are responsible for 60% of documented extinctions in all ecosystem ...

The goal of the survey is to monitor and assess abundance, population composition and recruitment of the off-shore Atlantic sea scallop (Placopecten magellanicus) resource.

The NOAA's Surge and Tide Operational Forecast System 2D Global (STOFS-2DGlobal) is a collaborative project designed to provide users with nowcasts and forecast guidance of water level conditions for the entire globe. This system is developed to serve the marine navigation, weather forecasting, and disaster mitigation communities. It uses the ADvan ...
