Tidal Current Survey of Long Island and Block Island Sounds

Abstract

in direct response to navigational requirements of the yachting, fishing, and maritime community, the Coast and Geodetic Survey of the U. S. Environmental Science Services Administration is presently engaged in an intensive tidal current survey of the Long Island and Block Island Sound area. The survey is being conducted by the U. S. Coast and Geodetic Survey Ship MARMER. One hundred and sixty current stations will have been occupied by the MARMER when the three year survey is completed in 1967. From one to three meters, equally spaced in the water column, are being operated at most of the stations. New Richardson current meters are being used at 23 of the stations for 15-and 29-day series, while the older Roberts meters are being used at the remainder for 100 hours. The reference station, for prediction purposes, is The Race. The results of the survey will be used to extend the coverage and increase the effectiveness of the “Tidal Current Tables” and “Tidal Current Charts, Long Island Sound and Block Island Sound.” Of particular note is the “Supplement” to the “Tidal Current Tables”, containing the results of the 1965 field work, which was published and distributed especially for the 1966 yachting season.
