T2.2: Analyses of foraminifera and coccoliths from core-tops, sediment traps and water column
samples for integration of proxy and present day records (D2.2; D2.5; Month 36)
UCAM: identify cores suitable for industrial era ; establish chronologies ; WS on paleo-tools;
Meeting to identify proxies and tools to be used and, strategy + sample distriburtion (2008)
UiB: cores suitable for industrial era ; establish chronologies ;
VU: sampling sediment trap analyse SNW + geochemistry (forams + coccos) ; distribute samples
CEREGE: participation in WS and meeting ; cocco morphometry from Drake passage and Med
AWI: participation in WS and meeting ; SNW on foraminifera; AFM on calcareous samples
from Mesocosm and culture experiments
UNIVBRIS: 11B, TE on sediment trap forams (Cape Blanc) + cultured material; provide input
on “tipping points” to WP13
Action: use the website to specify which samples from Mesocosm and culture experiments are of
interrest to WP3 (link to Theme 2)
T2.3: Analyses of cold water corals: field calibration and geochemistry (D2.5: Month 36)
CEA: 11B (and geochemistry) for the Holocene including industrial era
UNIVBRIS: geochemistry of recent warm water corals
T2.4: Determination of the dissolution kinetics of biogenic carbonates (D2.3: Month 36)
ULB: Laboratory experiments of dissolution kinetics of biogenic carbonates will be set-up
starting month 4. Coccoliths (Emiliania huxleyi) obtained from laboratory culture experiments
will be used in the initial dissolution studies to fine-tune the free-drift technique. Sediment trap
and core samples of biogenic carbonates will be obtained from WP2 partners (UCAM,
UNIVBRIS, CEREGE, AWI, VU). The choice of samples for the dissolution experiments will
be determined during the first WP2 meeting to be organised by UCAM in fall 2008. The results
will be examined in relation with geochemistry and with new proxies such as size normalized
weight.
T2.5: Model simulation (including a sediment module) of Glacial to Interglacial rain ratio and
carbonate compensation response (D2.7: Month 36)
UiB: during the coming 18 months:
1. Finalising a time transport model for the bioturbated sediment zone which enables consistent
comparison between real and simulated sediment cores.
2. Sensitivity experiments with annually averaged biogeochemical global ocean general
circulation model HAMOCC2 on varying glacial-interglacial rain ratios and their impact on the
sedimentary record (also sensitivitiy experiments with respect to other parameter variations than
rain ratio variations will be carried out in order to find out potential masking of signals;
parameters are e.g. dissolution rate constants, terrestrial CO2 outgassing, etc.).
3. Compilation of sediment core data from the real world to compare the model with (last
climatic cycle, variables wt% of caCO3 and opal, atm. ice core CO2, d13C benthic& planktonic).
UBern: Within 12 months, optimization of Bern3D sediment model parameters using gridded
sediment data of calcite and other quantities. Within 18 months, sensitivity experiments to
estimate impact of coral reef grow on the carbon cycle.
UNIVBRIS: Within 12 months for GENIE to delineate sensitivities and parameter space. Within
24 months for using the fully coupled FAMOUS model for a sub-set of the same experiments at
much higher resolution.
T2.6: Model simulation of Cretaceous/Paleogene acidification event (D2.4: Month 36)
GKSS/NERC-NOCS: set up model; first test runs
UNIVBRIS: first runs with GENIE; records (CCD, carb. accumlation, foram/cocco ratio) from 2
cores site (ODP1267; 1209)

Fortunate is willing to help as good as possible to achieve this deliverable,
however, other groups must contribute.

Notes:
1. For dataset deliverables where more than one institute is named, each named institute holds
responsibility for delivery of its own datasets. For other deliverables (reports) where more than
one institute is named, the institute with overall responsibility for delivery is denoted by an
asterisk.
2. The responsible PI’s for each institute (with respect to deliverables in this work package) are as
follows: UiB (Richard Bellerby), NERC-NOCS (Toby Tyrrell), SAHFOS (Peter Burkill), UGOT
(Leif Andersson), MRI-IS (Jon Olafsson) and IOC-UNESCO (Maria Hood).
3. Where institutes are listed as delivering datasets at months 18, 30, 42, and 48, it should be
recognized that this indicates an ongoing production of data throughout the project. Not all
institutes will generate new datasets for each date.
