Station  /   Lithologic Description

QH43  /   Rippled sand with scattered gravel. Abundant shell fragments (mostly quahog). Moon snails and their casings are present.
PICT0027	PICT0028	PICT0029
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.
PICT0030
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.
PICT0037	PICT0038	PICT0039	PICT0040
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.
PICT0031	PICT0032	PICT0033
QH47  /   Current-rippled sand with patchy loose organics and shell debris concentrated in the bedform troughs. Skate, seaweed (sea lettuce), sea urchins, and moon snail casings are present.
PICT0041	PICT0042	PICT0043
QH48  /   Abundant mussel shell debris over an undulating gravelly bottom. Skate and drifting red seaweed are present.
PICT0060	PICT0061	PICT0062
QH49  /   Rippled medium-grained sand with scattered pieces of drifting seaweed. Ripples are nearly symmetrical; ripple crests are slightly sinuous.
PICT0057	PICT0058	PICT0059
QH50  /   Numerous boulders with intervening gravel. Abundant kelp, Irish moss, and nondescript yellow, red, and green seaweed is present.
PICT0055	PICT0056
QH51  /   Rippled sand with isolated boulders. Ripples are faint; sea floor has an undulating appearance. Red seaweed and yellow sponges are attach to the boulders. Moon snails and casings are present.
PICT0053	PICT0054
QH52  /   Rippled medium-grained sand with shell debris concentrated in troughs. Whelk and shell being rafted by attached seaweed are present.
PICT0050	PICT0051	PICT0052
QH53  /   Rippled sand with shell debris (razor clam) concentrated in troughs. Nondescript seaweed, moon snails and casings are present.
PICT0044	PICT0045	PICT0046
QH54  /   Current-rippled sand with scattered shell debris and moon snail casings. Ripples have sinuous crests.
PICT0047	PICT0048	PICT0049
QH55  /   Coarse current-rippled sand with fine shell hash.
PICT0226	PICT0227	PICT0228
QH56  /   Coarse current-rippled brown sand with 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 snails, patches of abundant shell debris, scattered amphipod communities, and skate are present.
PICT0229	PICT0230	PICT0231
QH57  /   Current-rippled sand with 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 snails, scallops, and skate are present.
PICT0232	PICT0233	PICT0234
QH58  /   Current-rippled medium-grained brown sand with 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 snails, patches of abundant shell debris, and skate are present.
PICT0235	PICT0236
QH59  /   Gravel with abundant mussel shell debris, some sand, and scattered boulders. Red seaweed, starfish, kelp, and moon snail casings are present.
PICT0243	PICT0242
QH60  /   Boulders with intervening patches of gravel and mussel shell debris. Seaweed and starfish are present.
PICT0112	PICT0113	PICT0114	PICT0115
PICT0116
QH61  /   Mud with scattered shells and seaweed. Whelk are present.
PICT0163	PICT0164	PICT0165
QH62  /   Current-rippled sand on megaripples. Alternating bathymetric highs and lows suggest that they are the crests and troughs of sand waves and megaripples; ripple wavelengths increase toward wave crests. Shell debris (largely mussel shells) concentrated in sand-wave troughs. Moon snail casings are present.
PICT0034	PPICT0035	PICT0036
QH63  /   Muddy fine-grained dark olive gray sand with numerous burrows and patches of amphipod tubes. Sea floor is smooth and relatively flat with patchy shell debris and isolated clusters of seaweed present.
