REMAP was initiated to test the applicability of the EMAP approach to answer questions about ecological conditions at regional and local scales. Using EMAP's statistical design and indicator concepts, REMAP conducts projects at smaller geographic scales and in shorter time frames than the national EMAP program. The REMAP 1998 NY/NJ Harbor project was designed to support resource management decisions related to pollution control and remediation throughout the New York/New Jersey (NY/NJ) Harbor and to assist the New York-New Jersey Harbor Estuary Program (HEP) in developing a contaminant monitoring strategy to be included in the Comprehensive Conservation and Management Plan (CCMP) for the NY/NJ Harbor system. The New York/New Jersey Harbor System Sediment Assessment was based on methods used in the EMAP-Estuaries program. A probability-based sampling design ensured an unbiased estimation of condition and that all areas within the system were potentially subject to sampling. The probability based sampling design also allowed calculation of confidence limits around estimates of condition. Four sub-basins were sampled in the New York/New Jersey Harbor, including: Upper Harbor, Newark Bay, Lower Harbor (includes Raritan and Sandy Hook Bays) and Jamaica Bay. For purposes of this study, the region includes the lower portions of the Hudson, Passaic, Harlem, Hackensack and Raritan Rivers, upstream to a near-bottom salinity of 15 ppt, the East River to Long Island Sound and Lower Harbor to the Atlantic Ocean. The Station Location and Sampling Visit data sets provide geographic and visit information on the sites sampled in the New York/New Jersey Harbor region. The latitude and longitude for each station are given, as well as the area represented by a station. The water column depth at the time of sampling is reported. Most stations were selected probabilistically using a stratified random design; other stations were specifically located in a depositional area.
To provide accurate station location and visit information for each site visited in the NY/NJ Harbor region.

The latitude and longitude of the station location were determined at the time of sampling. According to EPA Locational Policy: 1. Latitude is always presented before longitude; 2. Latitude and longitude are recorded as decimal degrees. The specific method, Loran or GPS, of determining the latitude and longitude is also recorded.

Most values were assigned, based on geographic location.
One hundred and twelve sites were sampled, 28 in each of 4 sub-basins. All stations were sampled in 1998. Grab samples were collected in Newark Bay in 1999. Sites not in a depositional area were selected by randomly placing a grid structure over the study area, selecting 14 grid cells at random from each stratum, and selecting a random location from within the selected cells. Cells were of equal area within strata. Sampling was conducted from an USEPA vessel, the R/V CLEAN WATERS. Sampling Gear: LORAN-C Differential-GPS (D-GPS) Global Positioning System (GPS)
