Abstract

While there has been significant growth in marine sediment profile imagery (REMOTS(R) Sediment Profile Imagery) since the 1980s, reports of back-to-back Sediment Profile Imagery (SPI) with more traditionally generated benthic data are still quite rare. In May 1987, a SPI camera array was deployed at coastal sites in Ireland and France aspart of a demonstration project funded by the European Union. At each location, its effectiveness was evaluated against a background of ground truth data provided by grab and core sampling. This paper introduces data obtained in Galway Bay (west coast of Ireland) from sediment profile images collected in 1987 and in subsequent benthic recharacterizations (up to 1997) of some of the same biotopes, and compares selected SPI returns with those provided by the more traditional methods. The findings corroborate the view that SPI is a powerful sampling tool that is at its best when used in concert with a detailed, calibrated base derived from quality traditional sampling and sample processing.
