We present high-resolution records from subpolar North Atlantic sediments that are consistent with instrumental observations of surface and deep warming/freshening and in addition reconstruct the surface-deep relation of the last 1200 years. Sites from ~1300 meters and deeper suggest an ~0.5 degrees celsius cooling across the Medieval Climate Anomaly to Little Ice Age transition that began ~1350 ± 50 common era (CE), whereas surface records suggest asynchronous cooling onset spanning ~600 years. These data suggest that ocean circulation integrates surface variability that is transmitted rapidly to depth by the Atlantic Meridional Ocean Circulation, implying that the ocean moderated Earth’s surface temperature throughout the last millennium as it does today. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #--------------------------------------- # Site_Information # Site_Name: EN539_MC19A # Location: North Atlantic Ocean # Northernmost_Latitude: 61.42 # Southernmost_Latitude: 61.42 # Easternmost_Longitude: -21.89 # Westernmost_Longitude: -21.89 # Elevation_m: -1810 #--------------------------------------- # Data_Collection # Collection_Name: EN539_MC19A_iso # First_Year: 2003 # Last_Year: 1505 # Time_Unit: year Common Era # Core_Length_m: # Parameter_Keywords: carbon isotopes, oxygen isotopes # Notes: #--------------------------------------- # Chronology_Information # Chronology: Radiocarbon # Chronology_Download_Resource: https://www.ncei.noaa.gov/pub/data/paleo/templates/noaa-wds-paleo-14c-terms.csv # Chronology_Download_Description: Radiocarbon terms and definitions. # Chronology_Notes: Each radiocarbon date represents an average of 100 – 450 individuals of G. bulloides, picked from the > 250 or > 300 μm size fractions. # Rejection_Rationale: # Reservoir_Method: regional marine radiocarbon reservoir age correction ΔR = -108 and uncertainty of 40 years # Calibration_Method: Marine20 using Calib8.20 # Age_Model_Method: Bacon # Missing_Values: # Chronology_Table: # core_id depth_cm lab_code frac_mod frac_mod_1s age_14C_BP1950 age_14C_1s_yr age_calib_CE age_calib_pos2s_CE age_calib_neg2s_CE calib_curve delta_R_yr delta_R_err_yr date_used notes # MC19A 0.5 OS-112773 1.0263 0.0033 2003 Marine20 -108 40 yes 14C age > Modern and assigned as 2003 CE # MC19A 17.25 OS-113351 0.9489 0.0021 420 20 Marine20 -108 40 no Outside Marine20 curve # MC19A 26.25 OS-120552 0.9163 0.0021 700 20 1679 1511 1855 Marine20 -108 40 yes # MC19A 35.25 OS-117751 0.8937 0.0019 905 15 1493 1375 1649 Marine20 -108 40 yes #--------------------------------------- # Variables # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-var components: what, material, error, units, seasonality, data type, detail, method, C or N for Character or Numeric data) # ## Depth depth,,,centimeter,,Paleoceanography,,,N, ## Age age,,,year Common Era,,Paleoceanography,,,N, ## d13C.cw delta 13C,Cibicidoides wuellerstorfi,,per mil,,Paleoceanography,,,N, ## d18O.cw delta 18O,Cibicidoides wuellerstorfi,,per mil,,Paleoceanography,,,N, ## d13C.gb delta 13C,Globigerina bulloides,,per mil,,Paleoceanography,,,N, ## d18O.gb delta 18O,Globigerina bulloides,,per mil,,Paleoceanography,,,N, ## d13C.gi delta 13C,Globorotalia inflata,,per mil,,Paleoceanography,,,N, ## d18O.gi delta 18O,Globorotalia inflata,,per mil,,Paleoceanography,,,N, #------------------------ # Data: # Data lines follow (have no #) # Data line format -
