The system configuration can be tailored to the user's requirement, allowing for choice of beam widths as well as transmission modes. The minimum survey depth is from less than 3 meters below the transducers, and the maximum depth is approximately 2000 meters, somewhat dependant upon array size. Across track coverage (maximum swath width 140\u00c3\u0082\u00c2\u00ba) is up to 5.5 times water depth, to a maximum survey depth more than 2000 meters. The along track beamwidth depends upon the chosen transmit transducer configuration with 0.5\u00c3\u0082\u00c2\u00ba, 1\u00c3\u0082\u00c2\u00ba and 2\u00c3\u0082\u00c2\u00ba available as standard. The receive beam width is either 1\u00c3\u0082\u00c2\u00ba or 2\u00c3\u0082\u00c2\u00ba depending on the chosen receive transducer. The EM 710 operates at sonar frequencies in the 70 to 100 kHz range. The transmit fan is divided into three sectors to maximize range capability, but also to suppress interference from multiples of strong bottom echoes. The sectors are transmitted sequentially within each ping, and uses distinct frequencies or waveforms.\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n H13578_EM710\r\n \r\n \r\n \r\n \r\n completed\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n NOAA Ship Rainier\r\n \r\n \r\n \r\n \r\n 2021-03-11\r\n \r\n \r\n creation\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Rainier\r\n \r\n \r\n \r\n \r\n Homeported in Newport, Oregon, NOAA Ship Rainier is a hydrographic survey vessel that maps the ocean to aid maritime commerce, \r\n improve coastal resilience, and understand the marine environment.

The system is available in three separate configurations; one designed specifically for installation on small survey vessels and a 6000 meter depth rated system for either ROV or AUV use. Each of these configurations provides superlative data quality and ease of use over depths from 0.5 to 500 meters. Special emphasis has been put on maximizing operational efficiency and features such as variable swath width and roll stabilisation combined with a high ping rate and excellent data quality. The SeaBat 7125 provides a swath up to 165 degrees and uses up to 512 beams in operator selectable modes.\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Kongsberg EM710 Multibeam Echosounder\r\n \r\n \r\n \r\n \r\n \r\n EM710\r\n \r\n \r\n \r\n \r\n \r\n \r\n Kongsberg Maritime\r\n \r\n \r\n \r\n \r\n \r\n \r\n http://www.km.kongsberg.com/ks/web/nokbg0240.nsf/AllWeb/993132242751F5EDC1256FA300360548?OpenDocument\r\n \r\n \r\n \r\n \r\n \r\n \r\n resourceProvider\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n Kongsberg EM710\r\n \r\n \r\n \r\n \r\n Multibeam Echosounder\r\n \r\n \r\n The EM 710 multibeam echosounder is a high to very high resolution (up to 800 soundings per ping) seabed mapping system capable of meeting all relevant survey standards. The system configuration can be tailored to the user's requirement, allowing for choice of beam widths as well as transmission modes. The minimum survey depth is from less than 3 meters below the transducers, and the maximum depth is approximately 2000 meters, somewhat dependant upon array size. Across track coverage (maximum swath width 140\u00c2\u00ba) is up to 5.5 times water depth, to a maximum survey depth more than 2000 meters. The along track beamwidth depends upon the chosen transmit transducer configuration with 0.5\u00c2\u00ba, 1\u00c2\u00ba and 2\u00c2\u00ba available as standard. The receive beam width is either 1\u00c2\u00ba or 2\u00c2\u00ba depending on the chosen receive transducer. The EM 710 operates at sonar frequencies in the 70 to 100 kHz range. The transmit fan is divided into three sectors to maximize range capability, but also to suppress interference from multiples of strong bottom echoes. The sectors are transmitted sequentially within each ping, and uses distinct frequencies or waveforms.\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n","source_transform":null,"status":"error"}
