OB31A:
Biological Hot Spots in the Deep Sea: Natural Variability and Adaptation to Changing Oceans I

Session ID#: 93112

Session Description:
The deep-sea is often considered as the last wilderness on earth and provides habitat to many vulnerable and often unexplored ecosystems. These ecosystems support high species biodiversity and biomass, and provide goods and services that are vital for the health and wellbeing of our planet. Ecosystems such as cold-water coral and sponge reefs not only support a great diversity of life, but are also seriously affected by human activities and climate change. Biogeochemical dynamics, distribution, interconnections and adaptation of these ecosystems to anthropogenic change are key values to understand ecosystem functioning through time and make predictions for the future. This session will focus on benthic biological hotspot ecosystems in the deep sea, including seamounts, submarine canyons and continental slopes. Presenters are encouraged from different fields studying biogeographic patterns, biodiversity (macro to microscale), biogeochemistry, oceanography, paleoclimatological characteristics, and stressors of these fragile ecosystems.
