Diel changes of the Benthic Boundary Layer macrofauna over coarse sand sediment in the western English Channel

Zouhiri, S et al. (1996)

The Benthic Boundary Layer (BBL) macrofauna over a coarse sand community at Trezen Vraz (western English Channel) was sampled with a modified Macer-GIROQ hyperbenthic sledge to analyse its diel changes on two occasions, in November 1988 (9 hauls), and in July 1990 (11 hauls). Species composition of ...
