Unidentified burrow surface trace from the clyde sea area

Abstract

A previously unrecorded surface trace is described from a towed underwater TV survey of the southern Clyde Sea area. The trace comprises a mound with a single central opening, surrounded by a shallow trench with between 4 and 7 openings. The feature is approximately 10 cm in diameter, and occurred in pairs in the majority (76%) of observations. Spatial variability in the density of the feature was noted with densities estimated between 0.00134 and 0.0193 per m 2. The spatial distributions were analysed using quadrat and nearest-neighbour techniques, and were not found to be significantly different from random.
