Description 
Summary

The dataset combines fluorescent time-lapse sediment profile imaging (f-SPI) and diffusion gradient thin gels (DGT) to examine, in situ, the link between an important benthic ecosystem process (bioturbation) and ecosystem functioning (trace metal cycling) in Loch Creran, Scotland. The dimensions of the fg-SPI faceplate were 15x21.5cm (=322.50cm2), but after subtraction of the area occupied by the two DGT gels (=74cm2) the field of view reduces to 9x21.5cm (=248.5cm2). The camera (Nikcon D100, 2000 x 3000 pixels = 6 megapixels effective resolution = 75x75um per pixel) was set to an exposure of 1/60 f=2.0 and film speed equivalent to ISO 400. For each time-lapse sequence images were taken every 5 minutes for a period of 96h (n=1152 images per deployment). Three time-lapse movies are presented here to accompany Teal et. al. 2012 Biogeosciences. Data produced by Dr Lorna Teal (Institute for Marine Resources and Ecosystem Studies, IJmuiden), Dr Ruth Parker (Centre for Environment, Fisheries and Aquaculture Science), and Dr Martin Solan (National Oceanography Centre, Southampton).
