Analysis includes measurement of the radiogenic Nd isotope signatures progressively leached dolostone grains, picked from wet-sieved < 63µm sediment fraction of marine sediment downcores. The downcore records were sampled with resolution of about 1 kyr and cover roughly the last 33 ka. -58.03649999999999 -45.69 50.2 61.4639 -52.401625000000024 57.060559166666756 1999-08-01T00:00:00 1999-08-01T00:00:00 0.1 5.25 point HU84/30-21PC HU021 58.36767 -57.507 -2853.0 Core CORE HU91/45-094 HU094 50.2 -45.69 -3541.0 HUD91/45 HUD91/45 1991-10-01T00:00:00 1991-10-01 1991-11-01T00:00:00 1991-11-01 Hudson https://en.wikipedia.org/wiki/CCGS_Hudson Hudson https://en.wikipedia.org/wiki/CCGS_Hudson Core CORE HUD2008/29-004 PC04 61.4639 -58.0365 -2674.0 HUD2008/29 HUD2008/29 2008-01-01T00:00:00 2008-01-01 2008-12-31T00:00:00 2008-12-31 Hudson https://en.wikipedia.org/wiki/CCGS_Hudson Hudson https://en.wikipedia.org/wiki/CCGS_Hudson Core CORE MD99-2227 36C, MD27 58.210666666667 -48.373 Greenland Rise -3460.0 1999-08-01T00:00:00 MD114 MD114 IMAGES V IMAGES V 1999-08-01T00:00:00 1999-08-01 1999-09-30T00:00:00 1999-09-30 Marion Dufresne (1995) https://en.wikipedia.org/wiki/Marion_Dufresne_(1994) FNIN 9050814 Labeyrie, Laurent D Labeyrie, Laurent D hdl:10013/epic.42867.d001 Marion Dufresne (1995) https://en.wikipedia.org/wiki/Marion_Dufresne_(1994) FNIN 9050814 Calypso Corer CALYPSO 42.96 m 48 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ Event label Event Filippova Alexandra afilippova@geomar.de 0000-0002-3977-8122 Event Sample code/label Sample label Filippova Alexandra afilippova@geomar.de 0000-0002-3977-8122 Sample label Name Name Filippova Alexandra afilippova@geomar.de 0000-0002-3977-8122 Name DEPTH, sediment/rock Depth sed m depth http://purl.obolibrary.org/obo/PATO_0001595 sediment http://purl.obolibrary.org/obo/ENVO_00002007 rock Length L http://dbpedia.org/resource/Length Filippova Alexandra afilippova@geomar.de 0000-0002-3977-8122 Depth sed [m] AGE Age ka BP http://en.wikipedia.org/wiki/Kyr age http://purl.obolibrary.org/obo/PATO_0000011 Time T http://dbpedia.org/resource/Time Filippova Alexandra afilippova@geomar.de 0000-0002-3977-8122 Age [ka BP] ε-Neodymium ε-Nd Filippova Alexandra afilippova@geomar.de 0000-0002-3977-8122 SL-short leach (60 sec) ε-Nd (SL-short leach (60 sec)) ε-Neodymium ε-Nd Filippova Alexandra afilippova@geomar.de 0000-0002-3977-8122 LL- long leach (1 hour) ε-Nd (LL- long leach (1 hour)) ε-Neodymium ε-Nd Filippova Alexandra afilippova@geomar.de 0000-0002-3977-8122 NL- night leach (overnight) ε-Nd (NL- night leach (overnight)) ε-Neodymium ε-Nd Filippova Alexandra afilippova@geomar.de 0000-0002-3977-8122 RD- totally dissolved residual dolostone ε-Nd (RD- totally dissolved residua...) ε-Neodymium, standard deviation ε-Nd std dev ± standard deviation std dev https://en.wikipedia.org/wiki/Standard_deviation Calculated, 2 sigma Filippova Alexandra afilippova@geomar.de 0000-0002-3977-8122 ε-Nd std dev [±] CurationLevelC Enhanced curation https://wiki.pangaea.de/wiki/Curation_levels citable AMOC carbonate dissolution dolostone Heinrich Stadials Labrador Sea Late Quaternary Neodymium isotopes geomar author21697 author21870 author29590 author34016 author448 author96751 basis622 basis94 campaign21508 campaign3373591 campaign3376620 campaign3383345 campaign34217 campaign42019 curlevel30 event2025660 event2914801 event2914836 event2914839 geocode1 geocode1599 geocode1600 geocode1601 geocode2205 geocode8128 license21 method10861 method10902 method13011 param17761 param18991 param7369 param790 pi96751 term1073131 term1073135 term21621 term242 term37764 term38263 term41056 term43863 term43975 term47158 term47388 term47854 term49038 term71849 term71850 term835 topotype2
