Thursday, DEC 9 -
Arrival
1. ~9:00 PM:
Informal Ice-breaker, Meet at the IDEAL Bar & Grill at the base of the
Wharf
Introduction,
Presentations and Discussion
1. 8:30-9:00 Introductions and Overview, J . Zachos:
a. Objectives of the workshop.
b. PETM/IETM Research Updates
2. 9:00 12:30 Presentations/Discussion: Precipitation & the continental biosphere
Koch,
Wing*, Smith*, Beerling*, Bowen*, Harrington*, Gingerich*, Bloch*,
Meng*, Yuanqing*, Sloan*, Kelly*, Clifthorne, Shellito
Lunch 12:30-2:00
3. 2:00-5:30 Presentation/Discussion: Marine biota
and productivity
Bralower, Zachos*, Kelly*, Nielsen,
Brinkhuis*, Gibbs*, Raffi*, Hall*, Delaney, Paytan*, Faul*, Chung*, Sluijs*,
Hollis*, Lippert*
7:30 PM Group Dinner: Gilberts on the Wharf
*Required or have indicated a desire to present new findings or hypotheses. Given the limited focus of the themes, not everyone is expected to present. Please contact your group leader (underlined) with information on what you intend to present.
You will be limited to 5 slides and 5 to 10 minutes presentation time. Each group gets a total of 2.5 hours for presentations/discussions.
BREAKFAST: Do it yourself. I recommend Gildašs on the wharf.
COFFEBREAKS will be at ~ 10:30 and 3:30.
Discussions
(Continued)
1. 9:00-12:30 Presentation/Discussion Carbon Cycle
Dickens, Kump, Zachos, Rohl*, Bowen*, Panchuk*, Hilting*, Nicolo*,
McCarren*, Schellenberg, Bohaty, John, Sluijs
Lunch 12:30-2:00
2. 2:00 3:30 Meet in groups to d synthesize presentations/discussions. Groups should
focus on 1) key advances of the last two years, 2) unresolved issues, and 3)
possible solutions. The latter
should focus on observational data requirements, and how numerical models
should be integrated with observations.
3. 4:00 - 5:00
Reconvene - Group leaders
summarize the findings of each group (~15 mins each group)
4. 5:00-6:00
Executive Committee Meeting
Dinner: For
those who are interested, will arrange to meet at one of the downtown
restaurants on Pacific Ave.
BIOPE II THEMES:
1) Marine biota and productivity
a) Are the Ba (barite)
concentration anomalies reflecting increased organic carbon flux, changes in
bottom water/sediment redox conditions, or increased flux of Ba into the Ocean.
b) Are the shifts in nannofossil assemblages and
morphology indicating eutrophic conditions? Seasonally?
c) How does productivity change during
the PETM geographically? coastal vs
open ocean?
d) How do changes in climate,
atmospheric circulation patterns and runoff, impact vertical mixing and
productivity?
2)
Precipitation &
the continental biosphere
a)
How does precipitation change during the PETM including variation
geographically and temporally? New
evidence suggests both drier (or more seasonally dry) conditions and
wetter conditions on the continents.
What additional lines of evidence can we bring to bear on this? (flora, hydrogen isotopes of n-alkanes,
ichnofossils and other paleosol features, abundance of digging mammals?)
Productivity. Is there a method to estimate
this for continental environments?
b) Ross Secord is looking for the
canopy effect on carbon isotopes by comparing arboreal and terrestrial
herbivorous mammals. Could we use
this on PETM faunas to see if there is a change in canopy development.
c) Seasonality. Again, the body size and guild analysis of the fauna might help identify seasonality change.
3)
Magnitude of the global
carbon cycle perturbation
a) What is the timing and magnitude
of lysocline/CCD response (data), and how sensitive
is the CCD response to the magnitude and duration of CO2 input (either direct CO2 or CH4-->CO2)
(model)?
b) What is the spatiotemporal pattern
of carbon isotopic response during the PETM? (model and data)
c) What is the spatiotemporal
pattern of anoxia (model/data) and its biotic response (data)?
