B22B:
Deep-Sea Ecosystems: Natural Dynamics and Adaptation to Climate and Anthropogenic Change I


Session ID#: 8540

Session Description:
Recent explorations have revealed widespread and diverse ecosystems in the deep-sea. These spectacular deep-sea ecosystems support high species biodiversity, biomass or both. Furthermore, they provide goods and services that are vital for the health and wellbeing of our planet. Different habitats have formed in relation to topography, oceanography (e.g. currents), water chemistry, seafloor substrate and food availability. Ecosystems such as cold-water coral reefs and hydrothermal vents not only support huge diversity of life, but are also vulnerable to impacts of human activities and climate change.  Natural dynamics, distribution, interconnections and adaptation of these ecosystems to anthropogenic change are critical to understanding ecosystem functioning through time and to make predictions about the future. This session will investigate ecosystems in specific areas of the oceans, including seamounts, cold-seeps, submarine canyons and continental slopes. Presenters are invited from different fields studying biogeographic patterns, biodiversity, biogeochemistry, oceanography and paleo-climatological characteristics of these fragile ecosystems.
