Second OC3 Workshop

Ocean Circulation and Carbon Cycling during the Last Deglaciation:

Regional Syntheses of Carbon Isotope Data

Corvallis, Oregon, June 27-29, 2017


Earth's climatic transition from the Last Glacial Maximum (LGM) to the Holocene is still not fully understood. The associated rise in atmospheric CO2 remains unexplained although it is important for the global warming. Ocean circulation changes during the deglaciation have been linked to the rates of CO2 increase. However, the exact mechanism of that link is unclear and quantifying changes in the ocean's circulation and carbon storage remain challenging tasks. This workshop will contribute to making progress through new regional syntheses of carbon isotope data throughout the last deglaciation and comparisons of these syntheses to other paleoclimate proxy reconstructions and isotope enabled model simulations. We plan to address questions such as the following:

Objectives of the workshop are to

The workshop will be limited to ~40 participants. The format will be a limited number of oral presentations (e.g. from the leaders of the regional syntheses). Most presentations will be in poster format with short (2-3 min) lightning talks. A large amount of time will be devoted to detailed discussions and drafting of manuscripts. A detailed program will be published after the registration deadline.

Stakeholder Engagement

We will work with the Paleoclimate Modeling Intercomparison Project's (PMIP) working group Last Deglaciation. The purpose of that working group is to co-ordinate climate model simulations of the last deglaciation including comparison with reconstructions. For the latter purpose our carbon isotope syntheses and data constraints of ocean circulation will be useful. Members of this working group are encouraged to attend the meeting.

LinkedEarth is an NSF funded EarthCube project that aims at facilitating paleoclimate data syntheses. LinkedEarth team members are welcome to attend.

Travel Tips

From the International Airport in Portland (PDX) take the hutshuttle bus to Corvallis Hilton Garden Inn or rent a car. The bus takes about 2.5 h. Please plan to arrive on the 26th. We plan to start the meeting early morning on the 27th. Please plan to stay at least until noon on the 29th.


We have reserved rooms in the Hilton Garden Inn for $139/night from the 26th to the 30th. Call 541 752-5000 and mention "OC3 Workshop" to book your room there before June 5th. Of course you're free to book a different hotel or motel in Corvallis or camp in my backyard (just kidding).
