Nov 20, 2024 · The New York/New Jersey Operational Forecast System (NYOFS) has been implemented by NOAA's National Ocean Service (NOS) to provide the maritime user community with short-term predictions of water levels, water currents, water temperatures and salinity of the New York/New Jersey bays, and rivers.

We collect samples of harbor water at 85 sampling stations throughout New York Harbor. To view our harbor water sampling data as well as a map of the sampling station locations, visit Harbor Water Quality on NYC Open Data.

Jan 1, 2020 · Analyses of New York Harbor water quality reveal strong persistent geographic gradients and long-term trends in improving water quality. Data was synthesized for five indicators throughout the New York harbor region including: total nitrogen (TN), total phosphorus (TP), dissolved oxygen (DO), chlorophyll a (chl a ), and water clarity (secchi ...

The New York Harbor Observing and Prediction System (NYHOPS) was established to permit an assessment of ocean, weather, environmental, and vessel traffic conditions throughout the New York Harbor and New Jersey Coast regions.

Current salt-front location in the Hudson River (map, table, tab delimitted). Location, in river miles above The Battery, New York City, is a daily value for the most upstream location (at high slack tide) for the previous day.

The City of New York has been collecting water quality data in New York Harbor since 1909. These data are utlized by regulators, scientists, educators and citizens to assess impact, trends and improvement in the water quality of New York Harbor.

Little research has been done to compare salinity to biodiversity in the NY Harbor. Goals. The goal of this project is to test the hypothesis that salinity affects biodiversity by determining the species richness, Shannon entropy, and percent cover of organisms on settling tiles at four sites in New York Harbor.

Mar 21, 2025 · Salinity Management Assessment New York City Department of Environmental Protection 2 1 EXECUTIVE SUMMARY The New York City (NYC) Water Supply System provides drinking water to almost half the states population, which includes over 8.5 million people in New York City and one million people in upstate counties.

Abstract : The data presented in this report have been taken from a number of sources. Observations in Long Island Sound have been drawn from Riley and those for New York Bight from Ketchum, Redfield and Ayers. Winter values for Raritan Bay have been taken from Ayers, Ketchum and Redfield.

Nov 1, 2019 · Because of the absence of salinity data, salinity on the open boundary is specified using the averaged salinity of the North Atlantic Ocean (34.9 psu). Typically, the water density is controlled by salinity and temperature variations have little effect on it.
