Key Uncertainties in the Global Carbon-Cycle: Perspectives across terrestrial and ocean ecosystems

August 6-10, 2013
Boulder, CO

As part of the ASP Colloquium on
'Carbon-climate Connections in the Earth System':

The workshop will be the middle week of a 3-week Advanced Studies Program Colloquium at NCAR where graduate students will learn about terrestrial and ocean carbon cycles through lectures and exercises, and engage in group research projects focused on CMIP5 simulations. With the ASP colloquium students in attendance, this workshop provides an opportunity to introduce the next generation of scientists to the frontier of research.


The ocean and terrestrial biosphere currently absorb about half of annual anthropogenic CO2 emissions. These sinks are sensitive to climate; future warming will reduce their effectiveness. Understanding the mechanisms regulating natural carbon sinks is an essential element of climate prediction and a key challenge for Earth System models.


This colloquium is designed to bring together terrestrial and ocean carbon cycle scientists from across the world to explore key uncertainties the global carbon cycle. The aim is to build a dialogue crossing traditional disciplinary boundaries to address common conceptual challenges. Each topic covered will include an invited talk by a prominent terrestrial and ocean researcher and be followed by contributed talks and a poster session.

Topics include:

  • The State of the Carbon Cycle
  • Nutrient controls on carbon cycling
  • Remineralization pathways and climate
  • Role of individuals in ecosystem and carbon dynamics
  • Top-down controls on carbon cycling
  • Physical climate variability on carbon dynamics
  • Using observations to constrain model predictions

Confirmed Speakers include:

  • Tom Anderson (National Oceanography Centre Southampton)
  • Adrian Burd (UGA)
  • Jeff Chambers (LBNL)
  • Phillipe Ciais (IPSL-LSCE)
  • Curtis Deutsch (UW)
  • Rosie Fisher (NCAR)
  • Serita Frey (UNH)
  • Jeff Hicke (U of Idaho)
  • Taka Ito  (Georgia Tech)
  • Tim Lenton (Exeter)
  • Nicole Lovenduski (U of Colorado)
  • Galen McKinley (UW - Madison)
  • Kiona Ogle (ASU)
  • Jim Randerson (UC Irvine)
  • Ying Ping Wang (CSIRO)
  • Ning Zeng (U of Maryland)


This workshop is being supported by the Carbon Cycle Interagency Wroking Group and its U.S. Carbon Cycle Science Program, The Ocean Carbon and Biogeochemistry (OCB) program, and U.S. CLIVAR.
