The OTC have submitted 941 historical marine data sets to the Carbon Portal. These datasets were taken from the data product Surface Ocean CO2 Atlas (SOCAT) version 4,  and were collected on VOS lines currently in the ICOS labelling process.

These data were collected prior to 2015 when OTC came into being and has not gone through standardised processing and quality control in accordance to the ICOS data lifecycle. They can not be considered to be official ICOS data.
