WP2

Work Package 2. Data collection
WP leaders: Hilary Birks, Svein Olaf Dahl, and Bjørg Risebrobakken

The principal aim of WP2 is to provide empirical evidence from proxy data for changes in climate, circulation, and advection affecting the European Arctic 15-7 ka cal BP. This time period covers deglacial warming after the extreme cold of the LGM, including gradual and rapid warming and the abrupt YD cold reversal. Orbital forcing was strongest and seasonal contrasts were greater than today during the deglaciation. Boundary conditions in terms of albedo and land-ocean contrasts changed markedly, particularly influenced by the extent of sea-ice, from glacial to Holocene. Quantitative palaeoclimate proxy data and reconstructions will be acquired from both pre-existing data and new high-resolution, well-dated marine, terrestrial and ice-core climate proxy records with a wide spatial coverage. The data will be used to validate and test the results from the model experiments and associated hypotheses (WP1) in order to make a synthesis of dynamics, feedbacks, and rapid climate change (WP4.5).

WP 2 includes the following tasks with key personnel:
WP 2.1 Marine coring and analyses: Bjørg Risebrobakken (PI), Carin Andersson Dahl, Trond Dokken, Eystein Jansen.
WP 2.2 Terrestrial coring and analyses: Svein Olaf Dahl (PI), Jostein Bakke, Henriette Linge, Bjørn Kvisvik (PhD student), Atle Nesje, Darrell Kaufmann, Gerald Haug.
WP 2.3 Paleoclimate from biological proxies: Hilary Birks (PI), Ingelinn Aarnes (PhD student), John Birks, Anne Bjune, Ray Bradley, Stephen Brooks, Richard Telford.
WP 2.4 Seasonality reconstructions and associated dynamics: Jostein Bakke (PI), Carin Andersson Dahl, Hilary Birks, Anne Bjune, Svein Olaf Dahl, Trond Dokken, Eystein Jansen, Øyvind Lie, Atle Nesje, Bjørg Risebrobakken. 
WP 2.5 Ice-core records: Sigfus Johnsen and Jørgen Peder Steffenssen (PIs), Ingrid Seierstad.
