Here we report the first statistical validation of this proxy with satellite sea ice observations by combining bromine enrichment (with respect to seawater, Brenr) records from three Greenlandic ice cores (SIGMA-A, NU and RECAP) with satellite sea ice imagery, over three decades. We find that during the 1984-2016 satellite-era, ice core Brenr values are significantly correlated with first-year sea ice formed in the Baffin Bay and Labrador Sea supporting that the gas-phase bromine enrichment processes, preferentially occurring over the sea ice surface, are the main driver for the Brenr signal in ice cores. Moreover, in assessing Brenr's capability to record historical sea ice variability, we compare 20th-century Arctic Sea ice historical and proxy records with our reconstructions, based on an autoregressive-moving-average (ARMA) model, finding overall good agreement. While further enhancements are warranted, including site-specific calibrations and a comprehensive investigation into bromine transport-related concerns, this study presents a new method to quantitatively reconstruct past seasonal sea ice variability through bromine enrichment in ice cores.The SIGMA-A ice core processing and transportation was partly supported by Japan Society for the Promotion of Science (JSPS) KAKENHI Grant Numbers JP18H05292, and the Arctic Challenge for Sustainability II Program (ArCS II: JPMXD1420318865). Funding for retrieval and analysis of the NU ice core was provided by the US National Science Foundation (NSF) Arctic System Science Program award OPP-1205196 and ARC-1205062. Geospatial support for this work was provided by the Polar Geospatial Center under NSF-OPP awards 1043681 and 1559691. The RECAP ice coring effort was financed by the Danish Research Council through a Sapere Aude grant, the NSF through the Division of Polar Programs, the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, and the European Research Council under the European Community's Seventh Framework Programme (FP7/2007-2013)/ERC grant agreement 610055 through the Ice2Ice project and the Early Human Impact project (267696). This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement no. 689443 via project iCUPE (Integrative and Comprehensive Understanding on Polar Environments).Peer reviewedElsevierJapan Society for the Promotion of ScienceNational Science Foundation (US)Danish Research CouncilAlfred Wegener Institute Helmholtz Centre for Polar and Marine Research (Germany)European Commission#NODATA##NODATA##NODATA##NODATA##NODATA##NODATA##NODATA##NODATA##NODATA##NODATA##NODATA##NODATA##NODATA##NODATA##NODATA##NODATA#Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202420242024info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/371492https://api.elsevier.com/content/abstract/scopus_id/85207302972reponame:DIGITAL.CSIC.
