Synchronization of North Pacific and Greenland climates preceded abrupt deglacial warming. Science 345, 444 (2014). Please cite original reference when using this data. Not all alkenone and isotope samples were taken from precisely the same depth intervals. Some isotope samples were measured on 2cm interval samples, whereas alkenone measurements were conducted on 1cm samples. Therefore, some of the d18O sw calculations are based on alkenone temperature and d18O pairs that have minor offsets in the midpoint depth range. Nearly all of these pairs are within a decade of one another in the age model. # Provided Keywords: volcanism, deglacial, isostatic rebound, abrupt climate change #--------------------------------------- # Publication # Authors: Praetorius, S.K, A.C.

However, a direct link between regional climate change, isostatic adjustment, and the initiation of volcanism remains to be demonstrated due to the difficulty of obtaining high-resolution well-dated records that capture short-term climate and volcanic variability traced to a particular source region. Here we present an exceptionally resolved record of 19 tephra layers paired with foraminiferal oxygen isotopes and alkenone paleotemperatures from marine sediment cores along the Southeast Alaska margin spanning the last deglacial transition. Major element compositions of the tephras indicate a predominant source from the nearby Mt. Edgecumbe Volcanic Field (MEVF). We constrain the timing of this regional eruptive sequence to 14.6–13.1 ka. The sudden increase in volcanic activity from the MEVF coincides with the onset of Bølling–Allerød interstadial warmth, the disappearance of ice-rafted detritus, and rapid vertical land motion associated with modeled regional isostatic rebound in response to glacier retreat. These data support the hypothesis that regional deglaciation can rapidly trigger volcanic activity. Rapid sea surface temperature fluctuations and an increase in local salinity (i.e., d18Osw) variability are associated with the interval of intense volcanic activity, consistent with a two-way interaction between climate and volcanism in which rapid volcanic response to ice unloading may in turn enhance short-term melting of the glaciers, plausibly via albedo effects on glacier ablation zones. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Science Foundation # Grant: AGS-0602395, OCE-1204204 #--------------------------------------- # Site Information # Site_Name: EW0408-26TC/JC # Location: Gulf of Alaska # Country: # Northernmost_Latitude: 56.96 # Southernmost_Latitude: 56.96 # Easternmost_Longitude: -136.43 # Westernmost_Longitude: -136.43 # Elevation: -1623 #--------------------------------------- # Data_Collection # Collection_Name: EW0408-26TC/JC coarse Praetorius2016 # First_Year: 18160 # Last_Year: 400 # Time_Unit: cal yr BP # Core_Length: 8.92 # Notes: #--------------------------------------- # Chronology_Information # Chronology: # All radiocarbon data published in Praetorius & Mix, Science 345, 444 (2014): please cite original reference when using this data # Core core name # Depth midpoint depth in core # 14C Age calibrated radiocarbon age mixed planktonic foraminifera # 14C uncertainty radiocarbon age uncertainty NaN one standard deviation yr # Marine reservoir correction total marine reservoir correction NaN NaN yr # Marine13 age 2 s lower lower range of calibrated radiocarbon age NaN two standard deviation cal yr BP Calibrated using Marine13 (Reimer et al., 2013) # Marine13 age 2 s upper upper range of calibrated radiocarbon age NaN NaN cal yr BP Calibrated using Marine13 (Reimer et al., 2013) # Marine13 midpoint age midpoint age of calibrated radiocarbon age NaN NaN cal yr BP NaN # Tuned age controls tuned age controls allowing for variable marine reservoir age NaN NaN cal yr BP Tuned age based on tied d18O stratigraphy # Data NaN NaN NaN NaN NaN # All radiocarbon data published in Praetorius & Mix, Science 345, 444 (2014): please cite original reference when using this data NaN NaN NaN NaN NaN # Core Depth 14C Age 14C uncertainty Marine reservoir correction Marine13 age 2 s lower Marine13 age 2 s upper Marine13 midpoint age Tuned age controls # # EW0408-66JC 10.5 4585 20 595 + 50 4440 4725 4560 4560 # EW0408-66JC 53 8100 20 595 + 50 8245 8501 8370 8370 # EW0408-66JC 65 8695 25 595 + 50 8985 9279 9130 9130 # EW0408-66JC 85 10610 30 595 + 50 11254 11800 11530 11610 # EW0408-66JC 110 10730 40 595 + 50 11390 12023 11710 11710 # EW0408-66JC 151 10755 25 595 + 50 11450 12048 11750 NaN # EW0408-66JC 205 10900* 30 NaN NaN NaN NaN NaN # EW0408-66JC 215 10895 40 595 + 50 11841 12423 12130 NaN # EW0408-66JC 305 10930 30 595 + 50 11934 12452 12190 NaN # EW0408-66JC 355 10940 45 595 + 50 11926 12479 12200 12200 # EW0408-66JC 405 11085 35 595 + 50 12148 12597 12370 NaN # EW0408-66JC 455 11135 30 595 + 50 12251 12630 12440 NaN # EW0408-66JC 505 11115* 25 NaN NaN NaN NaN NaN # EW0408-66JC 565 11245 30 595 + 50 12481 12705 12590 NaN # EW0408-66JC 605 11335 35 595 + 50 12550 12764 12660 NaN # EW0408-66JC 705 11475 45 595 + 50 12623 12907 12770 12570 # EW0408-66JC 759 11615 30 595 + 50 12718 13060 12890 12700 # EW0408-66JC 805 11715 30 595 + 50 12809 13154 12980 12830 # EW0408-66JC 860 MEd 11250 50 595 + 50 13032 13222 13130 13130 # EW0408-66JC 904.5 11935 50 595 + 50 13076 13375 13230 13230 # EW0408-66JC 1162 12165* 30 NaN NaN NaN NaN NaN # EW0408-66JC 1273 12155 35 595 + 50 13273 13548 13410 13410 # EW0408-66JC 1370.5 12295 35 595 + 50 13389 13725 13560 13560 # EW0408-66JC 1374.5 12100* 70 NaN NaN NaN NaN NaN # # EW0408-26TC 0 NaN NaN NaN NaN NaN NaN 0 # EW0408-26TC 14.5 NaN NaN NaN NaN NaN NaN 11600 # EW0408-26TC 17.5 10330 40 735 + 50 10813 11133 10970 NaN # EW0408-26TC 31.5 NaN NaN NaN NaN NaN NaN 12700 # EW0408-26TC 47.5 12205 40 735 + 50 13236 13446 13340 13340 # # EW0408-26JC 1 12295 30 735 + 50 13277 13542 13410 13550 # EW0408-26JC 22.5 NaN NaN NaN NaN NaN NaN 13700 # EW0408-26JC 45.5 12855 40 735 + 50 13829 14162 14000 14000 # EW0408-26JC 88.5 13290* 35 NaN NaN NaN NaN NaN # EW0408-26JC 151 13195 30 735 + 50 14229 14991 14610 14610 # EW0408-26JC 180.5 13230 45 735 + 50 14270 15066 14670 14670 # EW0408-26JC 290.5 13840 40 735 + 50 15416 15969 15690 15690 # EW0408-26JC 480.5 15165 40 735 + 50 17369 17832 17600 17600 # EW0408-26JC 500 15235 35 735 + 50 17476 17887 17680 17680 # EW0408-26JC 891 15705 35 735 + 50 17977 18369 18170 18170 # # *Radiocarbon ages that are not included in the age model due to minor age reversals NaN NaN NaN NaN NaN NaN NaN NaN # # MEd: Mt.
