Stations 1-20

Station  /   Lithologic Description

WH1   /   Boulders and attached seaweed. The seabed becomes more gravelly and sandy and densely covered with eelgrass along the drift transect. Shell debris is present.
WH1A	WH1B	WH1C
WH1D	WH1E
WH2   /   Sand waves covered with current ripples. Shell debris collects in the ripple troughs. Gravel-rafted seaweed is common; starfish and skate are present.
WH2A	WH2B	WH2C
WH3   /   Sand waves covered with current ripples. Shell debris collects in the ripple troughs. Starfish are present.
WH3A	WH3B	WH3C
WH4   /   Rippled sand and megaripples. Shell debris is concentrated in the ripple troughs; shell debris and gravel up to cobble size are concentrated in the megaripple troughs. Attached seaweed and starfish are present.
WH4A	WH4B	WH4C
WH6   /   Rippled sand covered with eelgrass. Dead eelgrass collects in the ripple troughs. Trace of shell debris present.
WH6A	WH6B	WH6C
WH7   /   Rippled sand covered with eelgrass atop Nonamesset Shoal. Dead eelgrass collects in the ripple troughs.
WH7A	WH7B	WH7C
WH9   /   Sand waves covered with current ripples. Shell debris and coarser sand collects in the ripple troughs. Starfish and animal tracks (crab?) are present.
WH9A	WH9B	WH9C
WH10   /   Sand waves covered with current ripples. Shell debris, gravel, and dead eelgrass are concentrated in the ripple troughs. Gravel in troughs coarsens northeastward along drift track to as great as cobble size. Starfish and moon snails are present.
WH10A	WH10B	WH10C	WH10D
WH11   /   Boulders overgrown with seaweed and algae separated by patches of gravel and current-rippled sand. Sponges are common.
WH11A	WH11B	WH11C
WH11D	WH11E
WH12   /   Patchy rippled sand and cobble-sized and finer gravel. Some seaweed and debris. Red algae commonly grows on quahog shells.
WH12A	WH12B	WH12C
WH13   /   Current-rippled sand waves and megaripples. Shell debris is concentrated in the bedform troughs; drifting dead seaweed is common.
WH13A	WH13B	WH13C	WH13D
WH14   /   Current-rippled sand waves and megaripples. Shell debris is concentrated in the bedform troughs; drifting dead seaweed is common.
WH14A	WH14B	WH14C
WH15   /   Gravel-armored seabed with scattered algae-encrusted boulders. Patches of current-rippled sand covering the gravel are common. Some shells and shell debris, sponges, and seaweed are present.
WH15A	WH15B	WH15C	WH15D
WH15E	WH15F
WH16   /   Gravel-armored seabed with scattered algae-encrusted boulders. Patches of current-rippled sand covering the gravel are common. Starfish, sponges, and shells (primarily quahog) are present.
WH16A	WH16B	WH16C
WH17   /   Gravel-armored seabed with scattered algae- and barnacle-encrusted boulders. Patches of current-rippled sand covering the gravel are common. Starfish, moon snails, seaweed, sponges and a few shells are present.
WH17A	WH17B	WH17C	WH17D
WH17E	WH17F
WH18   /   Sand waves with gravel concentrated in the wave troughs. Scattered shells and shell debris and sponges. Sea floor becomes more gravelly along drift track.
WH18A	WH18B	WH18C
WH19   /   Current-rippled sand waves and megaripples. Some shell debris is concentrated in the troughs of the bedforms. Scattered clasts of gravel being seaweed-rafted are present.
WH19A	WH19B	WH19C	WH19D
WH20   /   Boulders overgrown with seaweed and encrusting biota with intervening patches of gravel adjacent to Nobska Point. Mussel-shell debris and living seaweed are abundant.
WH20A	WH20B	WH20C	WH20D
