...KYLE H. BROACH; MOLLY F. MILLER; SAMUEL S. BOWSER Abstract The abundant epifaunal scallop Adamussium colbecki and ophiuroid Ophionotus victoriae bioturbate the seafloor under the multi-year sea ice in Explorers Cove, western McMurdo Sound, Antarctica by churning the upper few centimeters...

... that encrust living shells of the Antarctic scallop Adamussium colbecki were compared within and between two sites located 30-km apart in McMurdo Sound, Ross Sea, Antarctica: Bay of Sails (BOS), an open coastal region with annual sea-ice cover, and Explorers Cove (EC), a protected embayment with multiannual...

..., such as seaweeds and glacial erratic boulders. Our specimens were collected on the scallop Adamussium colbecki in the same location as the cibicidids described by Mullineaux and DeLaca (1984) , Alexander and DeLaca (1987) , and Gooday and others (1996) . They were firmly cemented to the scallop shell ( Fig...

...FIGURE 1— Profusion of ophiuroids ( Ophionotus victoriae ), filter-feeding scallops ( Adamussium colbecki ), and sea urchins ( Sterechinus neumayeri ) on and among plates of anchor ice extending upward from the sediment surface. Eight km south of Explorers Cove. Scallop shells are ∼8 cm across. ...

... , of which living representatives settle preferentially on the circum-Antarctic scallop Adamussium colbecki (Smith) ( Mullineaux & DeLaca, 1984 ), on which they graze algae and bacteria, and erode the shell to parasitize on the host’s free amino acids ( Alexander & DeLaca, 1987 ). This species also...
