EP44C:
Topographic Influences on Oceanographic Processes, Marine Communities, and Ecology I Posters


Session ID#: 27897

Session Description:
Abrupt topographies such as seamounts, ridges, and submarine canyons can have dramatic impacts on local oceanography and therefore on the ecology, abundance, and diversity of 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) forcing relative to proximate habitats. The main focus of this session is on the nature of the impacts of abrupt topographies on physical and biological oceanographic processes on various scales. Biological scales range from meiofauna to megafauna and from phytoplankton to top predators, and physical processes from mesoscale to turbulence.
