the prism penetrates the top few centimetres of the seafloor
obtains a vertical cross section of the sediment-water interface by imaging the sediment in profile via a water-filled prism.
At each SPI station the camera was ‘hopped’ along the sea bed at 10m intervals, providing 5 images for analysis. Images were analysed using the software ImageJ for penetration depth, apparent redox penetration depth (aRPD) and surface roughness, following the method as described in Teal et. al (2010).
