| Definition | A sediment profile imaging (SPI) camera that provides in situ imaging of organism-sediment relationships on the seafloor. It obtains a vertical cross section of the sediment-water interface by imaging the sediment in profile via a water-filled prism. High resolution images of an area as large as 320 square centimetres of sediment profile are taken with each exposure. Optical clarity is not affected by local water conditions since the optical path is through air and distilled water. The current version incorporates a 24.1 megapixel Nikon DSLR camera. A variety of designs are available including ones for diver operation, for handheld operation in shallow environments, and with a lightweight aluminium frame for small boat operations. It is available in three housing materials and rated for either 1000 or 4000 m operation. Can be utilised to measure a wide variety of features including grain size, small-scale surface boundary roughness, dredged material thickness, apparent redox potential discontinuity depth, and surface microbial aggregations. The system is easily upgradeable with some systems built in the early 1990s still in use. | ||
