Research cruises and data

Since 1993, twenty-four UK research cruises have made measurements on the SR1b line across Drake Passage.  

Data from these cruises are available from BODC. Processed, quality-controlled CTD and water sample data are available from CCHDO.  Links are given in the table below.  Data should be acknowledged using the following text: "Data were collected and made publicly available by the international Global Ship-based Hydrographic Investigations Program (GO-SHIP; http://www.go-ship.org/) with National Capability funding from the UK Natural Environment Research Council to the National Oceanography Centre."

Completed cruises

Drake Passage repeat sections that have been occupied by the UK since 1993 are listed in the table below, with links to cruise reports and (where applicable) cruise blogs. For each cruise, links to the complete data inventory held by BODC and (where available) to processed hydrographic data held at CCHDO are included. The table also includes estimates of the volume transport and seasonally-adjusted transport-weighted mean temperature of water carried through Drake Passage by the Antarctic Circumpolar Current, computed as described here
