WH24   /   Rippled sand and seaweed at the mouth of Little Harbor. Shell hash and gravel-rafting of seaweed is common.
WH24A	WH24B	WH24C	WH24D
WH25  /   Flat, sandy seabed with abundant strands of dead eelgrass. Scattered live seaweed and dead horseshoe crabs and starfish are present.
WH25A	WH25B	WH25C	WH25D
WH26  /   Flat, undulating seabed composed of muddy sediment covered by an organic mat in Little Harbor. Small burrows and anchor line drop marks are common. Drift transect crosses the edge of a steep-sided pockmark. Sediment smelled strongly of hydrogen sulfide.
WH26A	WH26B	WH26C
WH27  /   Flat, undulating seabed composed of muddy sediment covered by an organic mat in Little Harbor. Small burrows and anchor-line drop marks are common. Sediment had a strong smell of hydrogen sulfide.
WH27A	WH27B	WH27C	WH27D
