BIOPE II Workshop Agenda, December 10-11, 2004

 

Thursday, DEC 9 - Arrival

 

1. ~9:00 PM: Informal Ice-breaker, Meet at the IDEAL Bar & Grill at the base of the Wharf

 

FRIDAY, DEC 10  (Twelve Winds Room, Coast Santa Cruz Hotel)

 

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.

 

 


 Saturday, december 11 (Alumni Room, University Center, UCSC)

 

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)?
