A.F." Andy the tree-ring stuff will all be collated in 1.1. I would suggest ice core data and varves would be better in 1.2 but would like Valerie to comment - in the meantime assume they are in 1.2. 1.4 does include peat and rhizopods. The CO2 from stomatal density does not fit in the project - we will get this information from the ice cores. Valerie , please comment when you can. Keith At 10:50 08/02/2005, you wrote: Dear Keith, Slowly I am getting an overview over Task 1.2 Yet there are still some points that need clarification from your part: - Does 1.1 include ice-core data, varves and tree rings? I assume so. This would then also signify that 1.1 would be responsible to collate long time series of tree-ring and varve data in relation to Holocene climate reconstruction - Does 1.4 include peat records and rhizopods? Seeing Dan Charman as one of the taskleader I assume so, which would also mean that 1.4 collates these data - What about CO2 reconstructions for the Holocene that do not derive from ice-cores? I am thinking of stomatal density derived CO2 records. They would fit into 1.5 but I am not sure whether the ice-core lobby will be happy to deal with them as they tend to show somewhat different results. Could you let me have a quick answer?
