Here, regional changes in oceanographic circulation and sea surface conditions are reconstructed based on organic-walled dinoflagellate cyst (dinocyst) assemblages from four cores collected from deep, central sites of the Baffin Bay corridor. All cores exhibit a major shift in dinocyst assemblages since the late glacial period. This shift consists of a change from a polar–subpolar heterotrophic species assemblage tolerating cold and near permanent ice-covered conditions, to assemblages characterized by a higher diversity and the occurrence of phototrophic taxa associated with mild conditions. Sea surface reconstructions from the modern analogue technique display a shift from harsh, quasi-perennial ice cover to warmer summer sea surface temperatures and a seasonal sea ice. South of the Davis Strait sill, this regime shift occurred at ca. 11.9 cal ka BP due to the influence of North Atlantic waters. Baffin Bay, however, remained densely sea ice covered until about 7.4 cal ka BP, when these warmer waters penetrated into Baffin Bay and mixed with the West Greenland Current (WGC). This mixing was facilitated by the retreat of the Greenland and Laurentide Ice Sheet (LIS) margins. A major change in Labrador Sea surface conditions occurred nearly at about the same time (~7.6 cal ka BP) when the strong stratification of surface waters weakened because of the reduction in meltwater supplies from the LIS that allowed winter convection and the inception of LSW formation. All these new records demonstrate large amplitude fluctuations in sea surface conditions tightly controlled by the relative strengths and shifts of the warmer WGC and colder Baffin Island Current. #------------------ # Publication # Authors: Kaufman, Darrell, Nicholas McKay, Cody Routson, Michael Erb, Basil Davis, Oliver Heiri, Samuel Jaccard, Jessica Tierney, Christoph Dätwyler, Yarrow Axford, Thomas Brussel, Olivier Cartapanis, Brian Chase, Andria Dawson, Anne de Vernal, Stefan Engels, Lukas Jonkers, Jeremiah Marsicek, Paola Moffa-Sánchez, Carrie Morrill, Anais Orsi, Kira Rehfeld, Krystyna Saunders, Philipp S.

We present a global compilation of quality-controlled, published, temperature-sensitive proxy records extending back 12,000 years through the Holocene. Data were compiled from 679 sites where time series cover at least 4000 years, are resolved at sub-millennial scale (median spacing of 400 years or finer) and have at least one age control point every 3000 years, with cut-off values slackened in data-sparse regions. The data derive from lake sediment (51%), marine sediment (31%), peat (11%), glacier ice (3%), and other natural archives. The database contains 1319 records, including 157 from the Southern Hemisphere. The multi-proxy database comprises paleotemperature time series based on ecological assemblages, as well as biophysical and geochemical indicators that reflect mean annual or seasonal temperatures, as encoded in the database. This database can be used to reconstruct the spatiotemporal evolution of Holocene temperature at global to regional scales, and is publicly available in Linked Paleo Data (LiPD) format. # #------------------ # Funding_Agency # Funding_Agency_Name: # Grant: #------------------ # Site_Information # Site_Name: CC04 # Location: Atlantic Ocean>North Atlantic Ocean>Davis Strait # Country: # Northernmost_Latitude: 61.4639 # Southernmost_Latitude: 61.4639 # Easternmost_Longitude: -58.0365 # Westernmost_Longitude: -58.0365 # Elevation: -2674 #------------------ # Data_Collection # Collection_Name: CC04.Gibb.2015 # Earliest_Year: 15598.0 # Most_Recent_Year: 18.882 # Time_Unit: cal yr BP # Core_Length: # Notes: #------------------ # Species # Species_Name: # Species_Code: # Common_Name: #------------------ # Chronology_Information # Chronology: # depth age SD age_type # 8.5 1690.0 35.0 age14C # 20.5 2380.0 25.0 age14C # 32.5 5085.0 35.0 age14C # 44.5 6790.0 35.0 age14C # 56.5 7315.0 30.0 age14C # 84.5 7735.0 30.0 age14C # 96.5 8780.0 60.0 age14C # 116.5 9290.0 30.0 age14C # 216.5 10990.0 45.0 age14C # 244.5 11400.0 120.0 age14C # 388.5 12700.0 60.0 age14C #------------------ # Variables # # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) # ## depth_merged depth,,,meter,,paleoceanography;climate reconstructions,,,N,depth_merged ## age age,,,calendar year before present,,paleoceanography;climate reconstructions,,,N, ## temperature sea surface temperature,dinoflagellate assemblage,,degree Celsius,winter,paleoceanography;climate reconstructions,,modern analogue technique,N,deVernal 2005 ## temperature-1 sea surface temperature,dinoflagellate assemblage,,degree Celsius,summer,paleoceanography;climate reconstructions,,modern analogue technique,N,deVernal 2005 # #------------------ # Data: # Data lines follow (have no #) # Data line format -
