It also includes the original oxygen profile data, recording the depeletion of oxygen as the sediment is penetrated. Samples were collected in the English and Dutch sectors of the Greater North Sea during three cruises on RV Cefas Endeavour (Cruise Codes CEND 15/09, CEND 11/10 and CEND 11/11).

The probe is driven ino the sediment in millimetre depth increments, recording the 'oxygen profile' which can be displayed graphically. The depth at which the probe first records zero oxygen is the Oxygen Penetration Depth. Records include data from Defra funded project ME5301 entitled "Mapping the structure, function and sensitivity of seabed sediment habitats to support assessment of the sea-floor status and the broadscale monitoring and management of the benthic environment" which sampled locations in the North Sea and western English Channel.
