Ocean Carbon and Biogeochemistry Workshop 2012

Abstract

Multiple stressors in marine ecosystems: Marine ecosystems are facing multiple anthropogenic stressors, and although we are learning much about how individual stressors may impact ecosystems, we know little about synergistic effects.

Ocean biogeochemistry from satellite data: Satellite ocean color data represent a critical observational resource in support of OCB research. Planning for the next NASA ocean color research mission PACE (Pre-Aerosol, Clouds, and ocean Ecosystem, http://decadal.gsfc.nasa.gov/PACE.html) is currently underway, with an anticipated 2019 launch.

Land-ocean transport and linkages with global change: Approximately 87% of Earth’s land surface is connected to the ocean by rivers. Over the past 50 years, increases in the human population have had severe global impacts on large-river systems through enhanced fertilizer usage, damming, deforestation, and many other land-use changes.

Integrating measurements across multiple time and space scales: Long-term biogeochemical studies conducted over decades at single locations (i.e. Ocean station Papa, HOT, BATS, CARIACO) or across large regional areas (i.e. CalCOFI / CCE-LTER) allow researchers to integrate and synthesize data over multiple temporal and spatial scales.

New observations from an Arctic Ocean in rapid transition: The Arctic is undergoing rapid changes in response to warming, accelerated melting of large ice sheets, and reductions in seasonal sea ice cover.
