PICT0210	PICT0211	PICT0212
QH24  /  Flat to undulating sea floor of burrowed muddy sand. Scattered seaweed and shells and a pipe are present. PICT0220
PICT0217	PICT0218	PICT0219	PICT0220
QH25  /  QH25 Boulders with intervening patches of gravel and burrowed sand. Kelp, nondescript seaweed, shell fragments, and starfish are common; fish are present.

QH30  /  QH30 Gravelly sand and shell fragments with starfish and scattered drifting and attached seaweed.
PICT0109	PICT0110	PICT0111
QH31  /   Boulders with intervening sandy gravel. Starfish, shell debris, small fish, and seaweed are present.
PICT0100	PICT0101	PICT0102	PICT0103
PICT0104
QH32  /   Gravelly sand and gravel with mussel shell debris. Moon snail casings are present.
PICT0105	PICT0106	PICT0107	PICT0108
QH33  /   Sandy gravel with scattered boulders and abundant shell debris. Starfish, stripper, and a school of fingerlings were observed in the bottom video.
PICT0087	PICT0088	PICT0089	PICT0090
PICT0091	PICT0092
QH34  /   Rippled medium-grained brown sand with scattered rocks near end of drift. Trace of loose organics, eelgrass, kelp, red seaweed and some tunicate patches are present.
PICT0093	PICT0094	PICT0095	PICT0096
PICT0097	PICT0098	PICT0099
QH35  /   Sandy gravel with some shell debris, loose drifting seaweed, moon snails, and starfish.
PICT0244	PICT0245
QH36  /   Gravel with scattered boulders. Pieces of loose drifting red seaweed, starfish, and shell debris are present.
PICT0246	PICT0247
QH37  /   Sandy gravel with scattered shell debris, seaweed, and patches of gravel. Sea floor has a current swept appearance.
PICT0240	PICT0241
QH38  /   Boulders with intervening patches of sand and shell debris. Kelp and nondescript seaweed cover the boulders.
PICT0237	PICT0238	PICT0239
QH39  /   Sand with low, broad ripples. Shell debris, amphipod tubes, worm burrows are concentrated in ripple troughs. Skates and moon snails are present.
PICT0016	PICT0017	PICT0018
QH40  /   Boulders with intervening patches of sand and shell fragments. Sponges, starfish, barnacles, and seaweed are common on the boulders. Small fish and soft corals are present.
PICT0019	PICT0020	PICT0021	PICT0022
PICT0023
QH41  /   Current-rippled sand with shell debris and moon snail casings. Organics concentrated in ripple troughs.
PICT0013	PICT0014	PICT0015
QH42  /   Current-rippled sand with fine gravel and razor clam shell debris concentrated in the troughs. Moon snails and small crabs are present; alternating bathymetric highs and lows suggest the crests and troughs of sand waves and megaripples.
