abstract: Knudsen Engineering 3260 CHIRP Subbottom - CHIRP Subbottom Profiler Data were Collected in Raw Knudsen SEG-Y Datagram Format
purpose: The National Oceanic and Atmospheric Administration (NOAA), on behalf of the United States Government, has a requirement to carry out surveys of specific regions on the continental margin (slope and rise) in the U.S. Atlantic margin and adjacent basin in order to obtain Raw Knudsen SEG-Y Datagram. 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 2000 to 5500 m in order to precisely define the location of 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 the data collected during the cruise.

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.
