EP012:
Topographic Influences on Oceanographic Processes, Marine Communities, and Ecology


Session ID#: 27897

Session Description:
Abrupt topographies such as seamounts, pinnacles, trenches, and submarine canyons can have dramatic impacts on local oceanography and therefore on marine communities. The biological communities living at, on, and around these features likely experience different hydrodynamic (enhanced current velocities, turbulence, and shear), geological (enhanced substrate and slope heterogeneity), and biological (enhanced POC flux, food, and nutrient availability) forcings relative to proximate habitats. Large gaps still exist in our knowledge of the true nature of the impacts of abrupt topographies on physical and biological oceanographic processes. How local ecology, abundance, and diversity are influenced as a result continues to be an area of active research and discovery with important implications for understanding habitat use, benthic and pelagic community dynamics, conservation, and fisheries management, and this will be the main focus for the session.
