ME31B:
Exploration and Research, and Assessment of Complex Deep-Sea Ecosystems: Recent Advances,  Holistic Approaches, and Future Challenges I


Session ID#: 11522

Session Description:
Submarine canyons and seamounts are topographically, geologically, and oceanographically complex features with environmental characteristics varying greatly along continental margins and seamount chains. These differences influence community structure among adjacent canyons or seamounts, yet we know little about what control they have across spatial and temporal scales. The dynamic nature of these environments, including intense currents, variability in upwelling conditions, nutrient transport, substrate type and availability can all influence habitat suitability, biodiversity, and biomass of benthic organisms. Furthermore, these habitats provide goods and services that are vital to our planet’s health, but are vulnerable to natural and human disturbance.  Recent expeditions exploring the Atlantic margin and eastern Caribbean utilizing high resolution multibeam mapping and remotely operated vehicles, have provided detailed maps of the region and enhanced our understanding of the biodiversity and distribution of deep-sea habitats. In conjunction with a better knowledge of environmental drivers, the intimate relationship between sessile fauna and the exposed substrate in submarine canyons and seamounts provides a framework for determining the relative age of geologic processes.  We invite synthetic presentations from national and international researchers investigating the complex relationships between ecology, geology, chemistry and physical oceanography in these deep-sea environments around the globe.
