Raw multibeam echosounder data collected on-board R/V Helmer Hanssen during the CAGE 17-2 AMGG cruise to the Olga Basin, northern Barents Seahttps://doi.org/10.18710/Q2ZVBCPanieri, GiulianaDataverseNO2023-02-222023-09-28T22:28:07Z<p>This dataset includes raw multibeam echosounder data collected on-board R/V Helmer Hanssen during the CAGE 17-2 AMGG cruise to the Olga Basin, northern Barents Sea between June 21st to July 3rd, 2017. Data were collected using a Kongsberg Simrad EM302 multibeam echosounder system. The nominal sonar frequency of the sound waves is 30 kHz with an angular coverage sector of up to 150° and 432 beams per ping. The system was typically used with a 60°/60° opening angle.</p> <p>The dataset comprises Kongsberg bathymetry files, as well as water column data files and sound velocity profiles gathered from 8 CTD casts. Water column data collection was not continuous during the cruise, for example during transits between study areas. </p><p>Data coverage includes the transit from Longyearbyen, Outer Storfjordrenna, the Olga Basin (Storbanken), and transit to Tromsø over West Sentralbanken, with files split according to their day of collection.
