Antecedent Geologic Controls on the Distribution of Oyster Reefs in Copano Bay, Texas
… of mostly estuarine mud with little sand or shell, large extents of oyster reefs and smaller areas of sand. Seismic stratigraphy analyses verify that the first oyster reefs in Copano Bay formed atop topographic highs in the Pleistocene surface. About 6 ka, sea level rise slowed to near its …

Geotechnical Investigation and Characterization of Bivalve-Sediment Interactions
… act as a strong underwater glue, adhering their shells to granular substrate. Some species of mussels have been shown to withstand water flow velocities greater than 6 m/s without detaching. For reference, riprap with a median grain size of about 655 mm has been shown to require a flow velocity …

Investigating a mitigation strategy for acidic sediment conditions in support of First Nation Bivalve restoration initiatives : the effect of shell hash on porewater pH and carbonate saturation states in Burrard Inlet, British Columbia, Canada
… carbonate dependent species, such as bivalve shellfish. Coastal sediment acidification may have disproportionate effects on bivalves. Shellfish are ecologically, economically, and socially significant in the Pacific Northwest. This research was guided by First Nation habitat restoration …

Decadal-scale evolution of a barrier island : Insights from storm overwash and shoreline change on Ocracoke Island, NC
… well-sorted fine to medium grained sand, coarse shell hash bases, and heavy mineral laminae. However, few cores had multiple deposits, indicating stacked overwash deposits are spatially and temporally variable. This collection of results shows the complexity of barrier island evolution and the …
