MIS 11 has received extensive study on the causes of its long duration and warmer than Holocene climate, which is anomalous in the last half million years. However, a major geographic gap in MIS 11 proxy records exists in the Arctic Ocean where fragmentary evidence exists for a seasonally sea ice-free summers and high sea-surface temperatures (SST; ~8-10 C near the Mendeleev Ridge). We investigated MIS 11 in the western and central Arctic Ocean using 12 piston cores and several shorter cores using proxies for surface productivity (microfossil density), bottom water temperature (magnesium/calcium ratios), the proportion of Arctic Ocean Deep Water versus Arctic Intermediate Water (key ostracode species), sea ice (epipelagic sea ice dwelling ostracode abundance), and SST (planktic foraminifers). We produced a new benthic foraminiferal d18O curve, which signifies changes in global ice volume, Arctic Ocean bottom temperature, and perhaps local oceanographic changes. Results indicate that peak warmth occurred in the Amerasian Basin during the middle of MIS 11 roughly from 410 to 400 ka. SST were as high as 8-10 C for peak interglacial warmth, and sea ice was absent in summers. Evidence also exists for abrupt suborbital events punctuating the MIS 12-MIS 11-MIS 10 interval. These fluctuations in productivity, bottom water temperature, and deep and intermediate water masses (Arctic Ocean Deep Water and Arctic Intermediate Water) may represent Heinrich-like events possibly involving extensive ice shelves extending off Laurentide and Fennoscandian Ice Sheets bordering the Arctic. #--------------------------------------- # Publication # Authors: Cronin, T.M., DeNinno, L.H., Polyak, L., Caverly, E.K., Poore, R.Z., Brenner, A., Rodriguez-Lazaro, J., and Marzen, R.E. # Published_Date_or_Year: 2014 # Published_Title: Quaternary ostracode and foraminiferal biostratigraphy and paleoceanography in the western Arctic Ocean # Journal_Name: Marine Micropaleontology # Volume: 111 # Edition: # Issue: # Pages: 118-133 # Report_Number: # DOI: 10.1016/j.marmicro.2014.05.001 # Online_Resource: # Full_Citation: # Abstract: The stratigraphic distributions of ostracodes and selected calcareous benthic and planktic foraminiferal species were studied in sediment cores from ~ 700 to 2700 m water depth on the Northwind, Mendeleev, and Lomonosov Ridges in the western Arctic Ocean. Microfaunal records in most cores cover mid- to late Quaternary sediments deposited in the last ~600 ka, with one record covering the last ~1.5 Ma. Results show a progressive faunal turn- over during the mid-Pleistocene transition (MPT, ~ 1.2 to 0.7 Ma) and around the mid-Brunhes event (MBE, ~ 0.4 Ma) reflecting major changes in Arctic Ocean temperature, circulation and sea-ice cover. The observed MPT shift is characterized by the extinction of species that today inhabit the sea-ice free subpolar North Atlantic and/or sea- sonally sea-ice free Nordic Seas (Echinocythereis sp., Rockallia cf. enigmatica, Krithe cf. aquilonia, Pterygocythereis vannieuwenhuisei). After a very warm interglacial during marine isotope stage (MIS) 11 dominated by the tem- perate planktic foraminifer Turborotalita egelida, the MBE experienced a shift to polar assemblages characteristic of predominantly perennial Arctic sea-ice cover during the interglacial and interstadial periods of the last 300 ka. These include the planktic foraminifera Neogloboquadrina pachyderma, the sea-ice dwelling ostracode Acetabulastoma arcticum and associated benthic taxa Pseudocythere caudata, Pedicythere neofluitans, and Polycope spp. Several species can be used as biostratigraphic markers of specific intervals such as ostracodes Rabilimis mirabilis - MIS 5 and P. vannieuwenhuisei extinction after MIS 11, and foraminiferal abundance zones Bulimina aculeata - late MIS 5 and Bolivina arctica - MIS 5-11. #--------------------------------------- # Publication # Authors: Cronin, T.S., Dwyer, G.K., Caverly, E., Farmer, J., DeNinno, L., Rodriguez-Lazaro, J., and Gemery, L. # Published_Date_or_Year: 2017 # Published_Title: Enhanced Arctic Amplification Began at the Mid-Brunhes Event ~400,000 years ago. # Journal_Name: Scientific Reports # Volume: 7 # Edition: # Issue: # Pages: # Report_Number: # DOI: 10.1038/s41598-017-13821-2 # Online_Resource: # Full_Citation: # Abstract: #--------------------------------------- # Publication # Authors: Marzen, R.E., DeNinno, L.H., and Cronin, T.M. # Published_Date_or_Year: 2016 # Published_Title: Calcareous microfossil-based orbital cyclostratigraphy in the Arctic Ocean # Journal_Name: Quaternary Science Reviews # Volume: 149 # Edition: # Issue: # Pages: 109-121 # Report_Number: # DOI: 10.1016/j.quascirev.2016.07.004 # Online_Resource: # Full_Citation: # Abstract: Microfaunal and geochemical proxies from marine sediment records from central Arctic Ocean (CAO) submarine ridges suggest a close relationship over the last 550 thousand years (kyr) between orbital- scale climatic oscillations, sea-ice cover, marine biological productivity and other parameters. Multiple paleoclimate proxies record glacial to interglacial cycles. To understand the climate-cryosphere- productivity relationship, we examined the cyclostratigraphy of calcareous microfossils and con- structed a composite Arctic Paleoclimate Index (API) "stack" from benthic foraminiferal and ostracode density from 14 sediment cores. Following the hypothesis that API is driven mainly by changes in sea-ice related productivity, the API stack shows the Arctic experienced a series of highly productive interglacials and interstadials every ~20 kyr. These periods signify minimal ice shelf and sea-ice cover and maximum marine productivity. Rapid transitions in productivity are seen during shifts from interglacial to glacial climate states. Discrepancies between the Arctic API curves and various global climatic, sea-level and ice- volume curves suggest abrupt growth and decay of Arctic ice shelves related to climatic and sea level oscillations. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: United States Geological Survey (USGS) Land Change Science Program # Grant: #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Lamont Doherty Earth Observatory # Grant: #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Science Foundation # Grant: DGE-1144155 #--------------------------------------- # Site_Information # Site_Name: Arctic Ocean Core Synthesis # Location: Arctic Ocean # Country: # Northernmost_Latitude: 88.87 # Southernmost_Latitude: 75.31 # Easternmost_Longitude: 179 # Westernmost_Longitude: -179 # Elevation: #--------------------------------------- # Data_Collection # Collection_Name: Arctic benthic d18O Cronin2019 # First_Year: 563900 # Last_Year: 2160 # Time_Unit: cal yr BP # Core_Length: # Notes: Benthic stable oxygen isotope values (table 4) are scaled to Uvigerina using constant correction of +0.64 per mil (Shackleton & Opdyke 1973) Oxygen isotopes (d18Ob) for C. teretis and O. tener are corrected to C. wuellerstorfi by applying corrections from Kristiansdottir et al.
