Seawater temperature records for the UK Shelf - 13 - Cefas Multibeam Acoustics - Sound Velocity Profile Temperature Data dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFASae4904aa-8bcd-4e70-8c77-f8d3d536d4a9 This dataset has been extracted as part of an exercise to assemble "all" Cefas Temperature Data and publish it in a Data paper. It is one of 17 Cefas data sources assembled. The RV Cefas Endeavour has been routinely deploying Multibeam acoustic measurement techniques since 2005, with particular emphasis being placed on habitat mapping projects (Brown and Vanstaen, 2008). As part of the calibration of the various acoustic systems, a CTD cast is performed at relevant stations to provide temperature data for the necessary calculation of sound velocity. The CTD used is a SAIV A/S SD204. Acoustic calibration data are stored along with the acoustic data, allowing temperature data to be extracted for this paper. 20160627 20150727
