Description:

Abstract:

Hudson River Benthic Mapping project. This data set consists of ship track along which side-scan sonar and acoustic subbottom profiles were acquired

Purpose:

These data were collected as part of the Hudson River Benthic Mapping Project. The purpose of the Hudson River Benthic Mapping Project of the New York State DEC is to create a comprehensive map of the bottom of the Hudson River, its sediment distribution and potential habitat classification.

Data_Quality_Information:

Logical_Consistency_Report:

Position of the ship was determined every second; any large departures from expected positions were analyzed.

Completeness_Report:

The data cover the whole Hudson River Estuary from Verrazano Bridge to Troy. Although areas of the Hudson River shallower then 4 m have not been surveyed and sampled completely.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Data are geo-referenced using differential GPS (DGPS) which results in a lateral accuracy of < +/- 1 meter.

Lineage:

Process_Step:

Process_Description:

NAVIGATION GPS navigation data were acquired from a pair of Ashtech Z-12 (dual-frequency 12-channel Y-Code) geodetic-quality GPS receivers, operated continuously at 2 Hz. One receiver was located on the ship and one was located at a fixed basestation at LDEO. The GPS data are post-processed with the KARS (Kinematic and Rapid Static) software package developed by G.Mader at the National Geodetic Survey (NGS). We solve for the relative position of the ship at each epoch with respect to the fixed basestation, which has been precisely located from a static solution with nearby stations in the CORS (Continuously Operated Reference Stations) network, and precise satellite orbit data obtained from the Crustal Dynamics Data Information System (CDDIS) archive. Differential processing allows us to remove clock errors and orbit errors which are common to both receivers. The tropospheric delay is modeled, and the ionospheric error is reduced by using both the L1 and L2 frequency observables. KARS uses an optimized integer-search algorithm to resolve initial satellite ambiguities and detect cycle slips. Final pseudorange corrected positions are accurate to 0.5 meters.

Spatial_Data_Organization_Information:

Indirect_Spatial_Reference:

The naming convention for profiles is as follows: the first two characters (letter and digit) refer to a survey area or tile as defined in the Hudson River Estuary Benthic Survey Index. The third character (e,w,n,s) designates the direction in which the line was shot (e-east, w-west, n-north, s-south). The remainder of the name is the line number in the survey area.
