        abstract:  Knudsen 320BR CHIRP subbottom data collected simultaneously with multibeam bathymetry and acoustic backscatter.
        purpose:  The National Oceanic and Atmospheric Administration (NOAA), on behalf of the United States Government, has a requirement to carry out surveys of the U.S. Atlantic continental margin in order to obtain multibeam bathymetry. In addition, high-resolution CHIRP seismic profiles were continuously collected and processed during the cruises. These data are required to support any potential claim for extended jurisdiction by the United States under United Nations Convention on the Law of the Sea (UNCLOS) Article 76. The requirement is for the collection and processing of full-coverage multibeam sonar data in water depths of approximately 1500 to 5000 m in order to precisely define the location of the 2500-m isobath and the "foot of the slope" as defined under UNCLOS Article 76. As part of their NOAA-funded research program, University of New Hampshire (UNH) researchers oversaw data acquisition, processing and archiving of all the data collected during the cruise.

        abstract:  The Marine Trackline Geophysics database contains bathymetry, magnetics, gravity and seismic navigation data collected during marine cruises from 1939 to the present. Coverage is worldwide. Data sources include both US and foreign oceanographic institutions and government agencies. This map service shows tracks (both ship and airborne) for all geophysical surveys in the database, split into sub-layers by data type. This dynamic map service allows these sub-layers to be toggled on/off: All Survey Types (0) - visible by default; Bathymetry (1); Gravity (2); Magnetics (3); Multi-Channel Seismics (4); Seismic Refraction (5); Shot-Point Navigation (6); Side Scan Sonar (7); Single-Channel Seismics (8); Subbottom Profile (9); Aeromagnetic Surveys (10). Separate cached (tiled) map services are also available for several of these layers: All Survey Types (http://maps.ngdc.noaa.gov/arcgis/rest/services/web_mercator/trackline_all_parameters/MapServer), Bathymetry (http://maps.ngdc.noaa.gov/arcgis/rest/services/web_mercator/trackline_bathymetry/MapServer), Gravity (http://maps.ngdc.noaa.gov/arcgis/rest/services/web_mercator/trackline_gravity/MapServer), Magnetics (http://maps.ngdc.noaa.gov/arcgis/rest/services/web_mercator/trackline_magnetics/MapServer), and Single-Channel Seismics http://maps.ngdc.noaa.gov/arcgis/rest/services/web_mercator/trackline_single_channel_seismics/MapServer).

            description:  The Chirp 3260 is designed for full ocean depth work where high transmit output power is a requirement. The Chirp 3260's 5U rackmount case can be fitted with up to six 2kW transmitter modules to output up to 12kW of total system power. The most common arrangement used by the research community worldwide is one 3.5 kHz channel configured for 10KW paired together with a 2KW, 12 kHz channel.

            description:  R/V Roger Revelle (AGOR 24) is a 274-foot (83 meter) research ship operated by the Scripps Institution of Oceanography, a graduate division of the University of California, San Diego. It is the sister ship of the R/V Atlantis, Woods Hole Oceanographic Institution's deep submergence support ship that carries the submersible Alvin. Revelle is the second of four new-generation AGOR oceanographic ships built by the U.S. Navy for operation by American oceanographic institutions. R/V Roger Revelle has a cruising speed of 12 knots and carries 22 crewmembers and 37 scientists.

                type:  Multibeam Echosounder
                description:  EM 122 multibeam echosounder is a high performance echosounder for deep water mapping with up to 288 simultaneous beams. The EM 122 is designed to perform seabed mapping to full ocean depth with an unsurpassed resolution, coverage and accuracy. The system is cost effective, reliable, and easily operated. The design of the EM 122 is based on more than 50 years of hydrographic experience with echo sounders, sonars and underwater positioning for civilian and military use. It is the latest model in a series of deep sea multibeam echo sounders started with the EM 12 in 1990 and followed by the EM 121 and the EM 120, of which about 40 systems are operational. It uses the same transducers as in the EM 120 but with new electronics and software. Compared with the EM 120 the EM 122 has up to four times the resolution in terms of sounding density through inclusion of multiping capability and more than twice the number of detections per swath. High density signal processing is a major improvement, to keep the acoustic footprint size small even for the outer beams in the swath. In typical ocean depths a sounding spacing of about 50 m across and along is achievable. The achievable swath width of the EM 122 is in the order of 30,000 m, or about 25% more than possible with the EM 120. This is obtained by using long FM chirps which gains about 15 dB in signal to noise ratio compared to CW pulses. The EM 122 is a complete system. All necessary sensor interfaces, data displays for quality control and sensor calibration, seabed visualization, and data logging are a standard part of the system, as is integrated seabed acoustical imaging capability (side scan). Including a higher frequency multibeam echo sounder such as EM 710 with the EM 122 system can give a total system solution meeting the strictest IHO requirements for all water depths. As proven with the EM 120, an accuracy of better than 0.2% of depth in deep waters is readily achievable with the EM 122.
