Physical oceanography
CTD stations	Quantity: number of stations = 31 Description: CTD casts made using a Seabird SBE 9/11 system with a transmissometer, optical backscatter, and fluorimeter mounted on a stainless steel frame with 24 10-litre bottles, although no water sampling was conducted during this expedition.
Geology and geophysics
Core - soft bottom	Quantity: number of stations = 31 Description: Piston, gravity, box and multicoring systems. Samples from the multicorer were taken from tubes measuring 8 x 60 and 4 x 100 mm. Subsamples from the box corer were also taken in 4 x 100 mm plastic tubes. Piston and gravity cores were 110 mm in diameter and were split on the ship, described and stored at 4�C in freezers in the hold prior to shipment to NOC, Southampton.
Geophysical measurements made at depth	Quantity: track kilometres = 1540 Description: Seismic surveys using Boomer and Sparker systems (hydrophone coupled to a Geomatrics Strataview R60 seismograph)
Multi-beam echosounding	Description: Bathymetric mapping performed using a multibeam Kongsberg EM302 Swath Mapper using a hull-mounted transducer. These data was recorded and processed shipboard using SIS Konsberg software.
Multichannel seismic reflection	Description: Edgetech SB-512i "Chirp" seismic reflection system optimized for imaging in the 20-200m sub-seafloor range.
