Station  /   Lithologic Description

QH43  /   Rippled sand with scattered gravel. Abundant shell fragments (mostly quahog). Moon snails and their casings are present.

QH44  /   Current-rippled sand with abundant shell debris concentrated in the troughs. Alternating bathymetric highs and lows suggest that they are the crests and troughs of sand waves and megaripples. Moon snail casings are present.

QH45  /   Current-rippled sand on megaripples. Alternating bathymetric highs and lows suggest that they are the crests and troughs of sand waves and megaripples. Patches of shell debris, skate, and congregated moon snails are present.

QH46  /   Current-rippled sand. Alternating bathymetric highs and lows suggest that they are the crests and troughs of sand waves and megaripples; wave crests are sandier. Shell debris (largely mussel shells) is concentrated in ripple and sand-wave troughs. Moon snail casings are present.
