National Estuarine Research Reserve System - NERRS - Nutrient and Pigment Data
Water quality observations made over long time periods can provide important feedback to scientists and to local, state, and national resource managers about actions taken to manage, protect, and restore estuaries. They also provide valuable information for evaluating the impacts of environmental change on coastal habitats and species. There are at least four water quality stations at each National Estuarine Research Reserve. Each station is designed to characterize long-term variability and short term changes in environmental conditions. Discrete samples for nutrient and chlorophyll a concentrations are collected at each long-term monitoring station at least once monthly. More intensive (24-hours over a complete tidal cycle) sampling is conducted each month at one water quality monitoring station to better understand impacts of tide and irradiance on nutrient cycling. Nutrient parameters collected include: nitrate, nitrite, ammonium, orthophosphate, and chlorophyll a. Numerous optional parameters include dissolved organic carbon, total dissolved nitrogen, and total dissolved phosphorous. The National Estuarine Research Reserves is a network of 30 reserves protected for long-term research, ecosystem monitoring, education, and coastal stewardship. Established by the Coastal Zone Management Act, the reserve system is a partnership program between NOAA and the coastal states. NOAA provides funding, national guidance, and technical assistance. Each reserve is managed on daily basis by a lead state agency or university with input from local partners. These data are collected as part of the NERRS System-Wide Monitoring Program (SWMP), which includes (1) abiotic indicators of water quality and weather; (2) biological monitoring; and (3) watershed, habitat, and land use mapping. Data were collected under individual Reserve NOAA grant/cooperative agreements and managed by the CDMO under NOAA grant/cooperative agreement #NA23NOS4200321 (2023) and prior grants.

Seagrasses
공공데이터포털
These data show aquatic vascular vegetation beds dominated by submerged, rooted, vascular species or submerged or rooted floating freshwater tidal vascular vegetation. This is not a complete collection of seagrasses on the seafloor, nor are the locations to be considered exact. The presence and location of the seagrasses have been derived from multiple state and federal sources.
NOAA's Estuarine Living Marine Resources (ELMR) Data Base
공공데이터포털
In 1985, NOAA launched the Estuarine Living Marine Resources (ELMR) Program to develop a consistent data base on the distribution, relative abundance, and life history characteristics of ecologically and economically important fishes and invertebrates in the Nation's estuaries. The Nationwide ELMR data base includes information for 153 species found in 122 estuaries and coastal embayments. Species are selected according to a set of criteria, which consider their commercial, recreational, and ecological value, as well as their utility as an indicator of environmental stress.The data base is divided into five study regions - West Coast, Gulf of Mexico, Southeast, Mid-Atlantic, and North Atlantic. For each species, five life stages are considered - adults, juveniles, larvae, spawning, and eggs - with some exceptions. Each estuary is subdivided into one to five salinity zones. Relative abundance is ranked by month for each life stage of each species, in each salinity zone of each estuary. The program utilized a consistent sampling strategy that enables comparisons to be made among species, specific life stages and times of year within, and to a lesser degree, among estuarine systems.In addition, a series of reports have been published which summarize the methods and results of the ELMR Program. These include a National report (2000), regional data summary reports for the North Atlantic (1994), Mid-Atlantic (1994), Southeast (1991), Gulf of Mexico (1992), and West Coast (1990), and regional life history summary reports for the West Coast (1991) and Gulf of Mexico (1997). Free copies of these reports are available upon request from the Biogeography Program (301-713-3028).
Estuarine Living Marine Resources: Southeast Regional Distribution and Abundance (NCEI Accession 0163992)
공공데이터포털
This is the original (1991) Southeast regional component of NOAA's Estuarine Living Marine Resources (ELMR) Project, a national database of ecologically and economically important fishes and invertebrates in the Nation's estuaries. The distribution and relative abundance are depicted in a consistent format for 40 species of fishes and invertebrates, in 20 estuaries in coastal North Carolina, South Carolina, Georgia, and the east coast of Florida. Species were selected according to a set of criteria, which consider their commercial, recreational, and ecological value. For each species, five life stages are considered - adults, juveniles, larvae, spawning, and eggs - with some exceptions based on individual species life history. Each estuary is subdivided into one to three salinity zones (Tidal Fresh, Mixing, and Seawater). Relative abundance was ranked on a five-tier scale by month for each life stage of each species, in each salinity zone of each estuary. Details of the methods for the original Southeast ELMR component can be found in Nelson et al. (1991) and Nelson and Monaco (2000).
Estuarine Living Marine Resources: West Coast Regional Distribution and Abundance (NCEI Accession 0161540)
공공데이터포털
This is the West Coast regional component of NOAA’s Estuarine Living Marine Resources (ELMR) Project, a national database of ecologically and economically important fishes and invertebrates in the Nation's estuaries. The distribution and relative abundance are depicted in a consistent format for 47 species of fishes and invertebrates, in 32 estuaries in coastal California, Oregon, and Washington State. Species were selected according to a set of criteria, which consider their commercial, recreational, and ecological value, as well as their utility as an indicator of environmental stress. For each species, five life stages are considered - adults, juveniles, larvae, spawning, and eggs - with some exceptions based on individual species life history. Each estuary is subdivided into one to three salinity zones (Tidal Fresh, Mixing, and Seawater). Relative abundance was ranked on a five-tier scale by month for each life stage of each species, in each salinity zone of each estuary. Details of the methods and resulting life history summaries for the West Coast ELMR component can be found in Monaco et al. (1990) and Emmett et al. (1991).
Ecological Marine Units: Nutrients
공공데이터포털
A compilation of ocean nutrient (nitrate, phosphate, and silicate concentrations) data at ¼ degree spatial resolution for the entire United States Exclusive Economic Zone. The dataset is derived from the ESRI Ecological Marine Unit (EMU) dataset, which was assembled from non-supervised statistical clustering of over 52 million points from NOAA’s World Ocean Atlas (2013) WoA database, an authoritative 57 year archive of global water column data. This derived dataset is divided into three separate point shapefiles, each representing either nitrate, phosphate, or silicate concentrations (all in units of μmol l-1). Values for nutrient concentrations represent a climatological average. Each shapefile is formatted such that a single point location (i.e., unique associated latitude and longitude) contains a unique column entry for a given depth interval. Depth intervals are variable from 5 m near the surface to 100 m in the deeper regions (> 2000 m) for a total of 102 depth levels. All disclaimers provided by the original dataset authors apply to this derived dataset. For detail on these disclaimers, please refer to the following reference: Sayre, R., J. Dangermond, D.

Coastal Maine Submerged Aquatic Vegetation Data 1993-1997 Geodatabase
공공데이터포털
Maine's eelgrass (SAV) meadows form an important aquatic habitat for the state. These meadows provide shelter for juvenile fish, and invertebrates. In certain locations they also help stabilize unconsolidated sediments and shorelines. Maine's Department of Marine Resources has mapped the SAV habitat for the entire coast using the Coastal Change Analysis Protocol. This mapping was accomplished from aerial photography acquired between 1993 and 1997. The unified coastal SAV data set is a composite of these multiple year data. The benthic data is classified according to the System for Classification of Habitats in Estuarine and Marine Environments (SCHEME). This system is fully described in "Development of a System for Classification of Habitats in Estuarine and Marine Environments (SCHEME) for Florida, Report to U.S. EPA - Gulf of Mexico Program, Florida Fish and Wildlife Conservation Commission, Florida Marine Research Institute.
