APT’s West of Shetlands geochemical database was purchased with publication rights by the NSTA in March 2017. In the interests of getting the data into the public domain for use by potential 30th Licencing Round applicants, the data is being delivered in the format it was received. Both of the spreadsheets in the delivery contain a "dataKEYS" tab which provide an explanation of what each tab in the spreadsheet contains. Users should also be aware that within the delivery, the index to the images associated with the delivery can be found within the spreadsheet "01_APT_WOSI-geochecm_data" under the tab marked "images".
