      <gmd:abstract>
        <gco:CharacterString>Acoustic backscatter data were collected on board the RRS James Clark Ross (cruise JR179) as part of the BIOFLAME-BIOPEARL programme. &#xD;
&#xD;
Data were collected using a Simrad EK60 echo sounder. Data were collected throughout the cruise which ran through the Drake Passage, Bellingshausen Sea and Amundsen Sea in the Southern Ocean, from February to April 2008. The raw data files (Simrad .raw format) are held by the Polar Data Centre (PDC) at the British Antarctic Survey (BAS).&#xD;
&#xD;
*******PLEASE BE ADVISED TO USE PROCESSED DATA*******&#xD;
&#xD;
The JR179 EK60 processed data is now available at https://doi.org/10.5285/ecc51062-1338-445e-bd3c-2e63487d1953.</gco:CharacterString>
