Description:

Abstract:

Surveys of the bathymetry and backscatter intensity of the sea floor south of Long Island, New York, were carried out in November 1998 using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard ship Frederick G. Creed. The purpose of the multibeam echosounder surveys was to explore the bathymetry and backscatter intensity of the sea floor in several areas off the southern coast of Long Island along the 20-meter isobath. Survey areas offshore of Fire Island Inlet, Moriches Inlet, Shinnecock Inlet, and southwest of Montauk Point were about 1 kilometer (km) wide and 10 km long. The area was mapped by the U.S. Geological Survey with support from the Canadian Hydrographic Service and the University of New Brunswick.

Purpose:

This data release makes multibeam echosounder data from the 1998 survey of the sea floor southwest of Montauk Point, New York, available in digital form. The navigation shapefile shows how the survey was carried out along tracklines running northeast-southwest approximately parallel to the local bathymetry and spaced about 100 m apart. The tracklines also can be used to identify data collected directly below the ship (at nadir).

Supplemental_Information:

Other data sets from this survey may be found in Butman and others (2016) (see larger work citation).

Data_Quality_Information:

Logical_Consistency_Report:

All navigation data were processed in the same manner. Navigation data were edited on-screen using the SwathEd routine jview to remove undesirable points, including turns at the ends of survey lines. Jview also rejects stray GPS fixes outside of the survey area, as set by the operator (see process steps for bathymetry). The Long Island surveys were assigned a block of line numbers beginning with 3000. GPS position data began to degrade on line 3045 and went out completely on line 3047. GPS data were regained on line 3048. The loss of navigation resulted in a data offset on lines 3045-3047. The offset is not corrected.

Completeness_Report:

This shapefile contains all edited tracklines from 1998 multibeam survey southwest of Montauk Point, New York. Other data sets collected offshore of Long Island, New York, on WHCMSC field activity 1998-015-FA may be found in Butman and others (2016) (see larger work citation).

The multibeam data were collected with a Simrad EM1000 multibeam echosounder mounted on the starboard pontoon of the Canadian Coast Guard ship Frederick G. Creed. The multibeam system utilizes 60 electronically-aimed receive beams spaced at intervals of 2.5 degrees that insonify a strip of sea floor up to 7.5 times the water depth. The horizontal resolution of the beam on the sea floor is approximately 10 % of the water depth. Vertical resolution is approximately 1 % of the water depth. Data were collected along tracklines oriented approximately northeast-southwest, parallel to the local isobaths, and spaced about 100 m apart. The frequency of the sonar was 95 kHz. Sound velocity profiles were obtained and input into the Simrad processing system to correct for refraction. Navigation was by means of differential GPS. Operation of the Simrad EM1000 was carried out by hydrographers of the Canadian Hydrographic Service. The data were collected on Woods Hole Coastal and Marine Science Center field activity 1998-015-FA.
