Two competing models attempt to describe the stimulus for HEs via either internal ice sheet oscillations or external ocean-climate system forcing. We present a terrestrial record of HEs from the northeastern LIS that strongly supports ocean-climate forcing. Subglacial carbonate precipitates from Baffin Island record episodes of subglacial melting coincident with the three most recent HEs, resulting from acceleration of nearby marine-terminating ice streams. Synchronized ice stream acceleration over Baffin Island and Hudson Strait is inconsistent with internal ice sheet oscillations alone and indicates a shared ocean-climate stimulus to coordinate these different glaciological systems. Isotopic compositions of these precipitates record widespread subglacial groundwater connectivity beneath the LIS. Extensive basal melting and flushing of these aquifers during the last HE may have been a harbinger for terminal deglaciation.<\/jats:p>","DOI":"10.1126\/sciadv.abp9329","type":"journal-article","created":{"date-parts":[[2022,10,19]],"date-time":"2022-10-19T17:57:23Z","timestamp":1666202243000},"source":"Crossref","is-referenced-by-count":5,"title":["Terrestrial evidence for ocean forcing of Heinrich events and subglacial hydrologic connectivity of the Laurentide Ice Sheet"],"prefix":"10.1126","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3285-4858","authenticated-orcid":true,"given":"Graham H.","family":"Edwards","sequence":"first","affiliation":[{"name":"Department of Earth Sciences, Dartmouth College, Hanover, NH 03755, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0029-0709","authenticated-orcid":true,"given":"Terrence","family":"Blackburn","sequence":"additional","affiliation":[{"name":"Department of Earth and Planetary Sciences, University of California Santa Cruz, Santa Cruz, CA 95064, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7637-9796","authenticated-orcid":true,"given":"Gavin","family":"Piccione","sequence":"additional","affiliation":[{"name":"Department of Earth and Planetary Sciences, University of California Santa Cruz, Santa Cruz, CA 95064, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9711-4332","authenticated-orcid":true,"given":"Slawek","family":"Tulaczyk","sequence":"additional","affiliation":[{"name":"Department of Earth and Planetary Sciences, University of California Santa Cruz, Santa Cruz, CA 95064, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8225-2740","authenticated-orcid":true,"given":"Gifford H.","family":"Miller","sequence":"additional","affiliation":[{"name":"Institute of Arctic and Alpine Research and the Department of Geological Sciences, University of Colorado, Boulder, CO 80309, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6542-5972","authenticated-orcid":true,"given":"Cosmo","family":"Sikes","sequence":"additional","affiliation":[{"name":"Department of Geology, University of Maryland, College Park, MD 20742, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"221","reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0277-3791(01)00095-6"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1172873"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/s43017-020-00106-y"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1029\/2003RG000128"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1064618"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1130\/0016-7606(1977)88<1813:LQDOIS>2.0.CO;2"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/0033-5894(88)90057-9"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1029\/93PA02200"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1029\/97PA00581"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1104772108"},{"key":"e_1_3_2_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.margeo.2017.09.002"},{"key":"e_1_3_2_13_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0025-3227(98)00054-1"},{"key":"e_1_3_2_14_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature21069"},{"key":"e_1_3_2_15_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-022-31754-x"},{"key":"e_1_3_2_16_2","doi-asserted-by":"publisher","DOI":"10.5194\/cp-15-153-2019"},{"key":"e_1_3_2_17_2","doi-asserted-by":"publisher","DOI":"10.1038\/nature03059"},{"key":"e_1_3_2_18_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.quascirev.2011.02.003"},{"key":"e_1_3_2_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/2016PA003028"},{"key":"e_1_3_2_20_2","doi-asserted-by":"publisher","DOI":"10.1126\/science.aag1015"},{"key":"e_1_3_2_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.quascirev.2014.10.032"},{"key":"e_1_3_2_22_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.earscirev.2015.01.011"},{"key":"e_1_3_2_23_2","doi-asserted-by":"publisher","DOI":"10.1130\/G32335.1"},{"key":"e_1_3_2_24_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.yqres.2013.10.014"},{"key":"e_1_3_2_25_2","doi-asserted-by":"publisher","DOI":"10.1029\/2002GL015192"},{"key":"e_1_3_2_26_2","doi-asserted-by":"publisher","DOI":"10.1029\/RG015i002p00235"},{"key":"e_1_3_2_27_2","unstructured":"C.
