Members of the oyster family Chamidae are common in Indo-Pacific subtidal habitats, adhering to the sides of rocks, where they are usually well hidden by a fine growth of algae that extends equally over the rocks and the oyster shells (Purchon 1968). Chamidae species are known for their efficient filter-feeding abilities and thus may compete with other benthic filter-feeders for both space and ...

Here, we evaluated the potential of using bathymetric Light Detection and Ranging (LiDAR) to characterise shallow water (<30 m) benthic habitats of high energy subtidal coastal environments. Habitat classification, quantifying benthic substrata and macroalgal communities, was achieved in this study with the application of LiDAR and underwater video groundtruth data using automated classificatio...

An understanding of subtidal coastal sea level fluctuations is important both because they impact the effect of tsunamis and other destructive events on human developments and because many physical and biological processes within coastal ecosystems are very sensitive to these fluctuations. We analyze a time series of subtidal fluctuations at Crescent City, California, during 1980–91 using the m...

Shell resource utilization in two common species of hermit crabs, Calcinus latens (Randall) and Calcinus gaimardii (H. Milne Edwards), from intertidal and subtidal zones at Kenting, southern Taiwan, was studied. Field data were compared with laboratory results in shell-selection tests. Shell parameters examined included shell length, shell width, aperture length, aperture width, and weight in s...

Flux calculations demonstrate that many estuaries are natural filters for trace metals. Yet, the underlying processes are poorly investigated. In the present study, it was hypothesized that intertidal marshes contribute significantly to the contaminant filter function of estuaries. Trace metal concentrations and sediment characteristics were measured along a transect from the subtidal, over an ...

To investigate community shelter effects of two invasive decapod species, Hemigrapsus sanguineus and Carcinus maenas, in the Long Island Sound (LIS), we deployed artificial shelters in the intertidal and immediate subtidal zones. These consisted of five groups during the summer: a control, a resident H. sanguineus male or female group, and a resident C. maenas male or female group. We quantifie...

Title of Thesis: THE EFFECT OF AQUACULTURE GEAR AND TIDAL ZONE ON THE GROWTH AND SHAPE OF THE OYSTER CRASSOSTREA VIRGINICA DURING A “FINISHING PERIOD” IN CHESAPEAKE BAY. Laura Landis Thomas, Master of Science, 2016 Thesis directed by: Assistant Professor, Louis V. Plough, Marine Estuarine Environmental Science Research Professor, Jeffrey C.

Three and a half years of hydrographic, velocity, and meteorological observations are used to examine the dynamics of upper Elkhorn Slough, a seasonally inverse, shallow, mesotidal estuary in central California. The long-term observations revealed that residual circulation in Elkhorn Slough is seasonally variable, with classic estuarine circulation in the winter and inverse estuarine circulatio...
