Update VDatum for the New York Bight, New York Harbor, Hudson River, Long Island Sound, and Narragansett Bay: tidal datums and their associated spatially varying uncertainties, and sea surface topography

This technical memorandum documents the update of the tide model and modeled tidal datums, the calculation of tidal datum spatially varying uncertainties, and the creation of the topography of sea surface (TSS) field and TSS spatially varying uncertainty field in the New York Bight, New York Harbor, Hudson River, Long Island Sound, and Narragansett Bay. The initial development and application of a tidal datum model in this region was made in 2001 (Hess 2001), and the previous update of the tidal datum model in this region was done in 2008 (Yang et al., 2008).
