Title: NOAA Tidal Current Data for the Coastal United States
Short Name: currents
Status: In Work
Publication Date: 2009
Abstract:

Knowledge of the timing and strength of tidal currents is extremely important for safe navigation in coastal waters. Tidal currents are almost always the strongest current experienced by vessels operating offshore and for considerable distances inside bays and river estuaries. Standardized procedures exist for analyzing tidal current data to separate the tidal and nontidal parameters. The tidal parameters are used to produce the National Ocean Service Tidal Current Tables. There are currently 41 tidal current reference stations where daily predictions are made based on information obtained in short-term current studies. Additional predictions are made for 2200 locations referenced to these tidal current reference stations. Predictions have varying degrees of accuracy dependant on the age of the data, the length of the measurements and the degree of non tidal influence a given location experiences. A clear understanding of current patterns in ports and estuaries which have economical and commercial importance is vital to ensure safe navigation and help in preventing accidents. In ports where currents are dominated by non-tidal factors, real-time current measurements are preferred.

Purpose:

The mission of the National Ocean Service, Center for Operational Oceanographic Products and Services is to provide the national infrastructure, and the scientific and technical expertise to monitor, assess, and distribute tide, current, water level, and other coastal oceanographic products and services necessary to support NOAA's mission. An important aspect of this mission is promoting safe navigation and improving the efficiency of the maritime industry and the economic productivity of U.S. ports by providing real-time current observations, predictions, forecast, and other coastal oceanographic information

Access Information

Security Class: Unclassified
Data Access Procedure:

Recent current observations exist where a National Ocean Service (NOS) PORTS is installed. Data collected since May 1999, can be accessed and downloaded from the Current Data Retrieval page (http://tidesandcurrents.noaa.gov/station_retrieve.shtml?type=Current+Data). Historical current data prior to 1999 are available by special request.; PORTS data can also be obtained over the telephone. Toll free numbers are provided for each PORTS location online at http://tidesandcurrents.noaa.gov/ports.html;

Data Access Constraints:

None

Data Use Constraints:

Preliminary data have not been subjected to the National Ocean Service's quality control or quality assurance procedures and do not meet the criteria and standards of official National Ocean Service data.
