Synthesis of in-situ data For informing models and towards identification of ‘tipping points’ and ‘hot spots’ Synthesise EPOCA in-situ data and also data from outside the project Thomas et al., 2008, submitted. Feely et al., 2008, Science Express. Tyrrell et al., 2008, Biogeosciences.
Milestones and Deliverables Most deliverables are quality-controlled in-situ datasets…
First Milestone Get advice from modellers on data collection, and produce report thereon (month 3) What in-situ data would be most useful, and in what format would you prefer it presented?
Deliverable Atlas of calcifier historical trends and biogeographical changes over time, according to CPR data (month 24) Note: (Abundance is average numbers of individuals per CPR sample)
WP 3: RISKS • cruise cancellations • instrument failures • data fails QC • … WP 3: DEPENDENCIES • advice from modellers on what data to collect and what form to present it in
