Funding Information:
Funding for fieldwork for this study was provided by a Ph.D. scholarship from the University of Plymouth, U.K. with additional funding to MLV for field campaigns to sample the Lower Cretaceous of Festningen from the Geological Society, London, UK (Gloyne Outdoor Geological Research fund, 2014); to MLV, MEJ and IM from the National Geographic Society's Committee for Research and Exploration grant number CP-038R-17; and to MLV from The British Sedimentological Research Group Gill Harwood Memorial Fund (2015), and an American Association of Petroleum Geologists grant-in-aid (William E. Gipson Named Grant, 2015). We kindly thank Trude Hohle for invaluable field assistance for MLV, MEJ and KKS in the 2018 campaign at Kvalvågen, Spitsbergen, and Dr. Meriel FitzPatrick for field assistance during the 2014 field campaign. Field work to collect samples from the uppermost Jurassic-lowermost Cretaceous portion of the Festningen section was supported by Bundesanstalt für Geowissenschaften und Rohstoffe (BGR) [Federal Institute for Geosciences and Natural Resources] under the Circum-Arctic Structural Events (CASE) program in 2015 (lead Dr. Karsten Piepjohn). Collections were made by JMG with assistance from SG and LR. Canadian field work was supported by the GeoMapping for Energy and Minerals (GEM) Program (Natural Resources Canada, Geological Survey of Canada) with funding to JMG. Collections were made by JMG with support from Dr. Lisa Neville (GSC Calgary), Kyle Sulphur (GSC Calgary), and Pilipoosie Iqaluk (Hamlet of Resolute Bay, NU) in 2015. Dr. Keith Dewing is thanked for HALIP project activity management. Logsitics support for this work was provided by the Polar Continental Shelf Program (NRCan) and UHL Helicopters (Pilot Lorne Pike). We are grateful for the staff of the Environment and Climate Change Canada Eureka Weather Station and, in particular, Station Manager André Beauchard, where the work was staged from. Mercury, elemental, and sequential pyrolysis of the samples from the uppermost Jurassic-lowermost Cretaceous portions of the Festningen section were funded by a AIAS-COFUND II fellowship programme supported by the Marie Skłodowska-Curie actions under the European Commission's Horizon 2020 (grant agreement no. 754513) and the Aarhus University Research Foundation to JMG (2019-2020). This grant also financially supported Hg analysis of the Kvalvågen section. Data cited from Galloway et al. 2020 are acknowledged therein. Funding was also provided for this study by the European Commission, Horizon 2020 (ICECAP; grant no. 101024218, to MLV), and from the Research Council of Norway through the Centres of Excellence funding scheme, project number 223272. Further funding was provided by the Danish Council for Independent Research–Natural Sciences (project DFF-7014-00142), to CK.; the Canada Research Chairs program to FW. Mercury analyses at the University of Oxford were supported by the Leverhulme Trust and Natural Environment Research Council Grant NE/G01700X/1 and ERC consolidator Grant (ERC-2018-COG-818717-V-ECHO) (to TAM) and PhD studentship NE/L501530/1 (to LMEP), with geochemical standard material provided by John Farmer and the University of Edinburgh. We thank Andrew Kingston for an internal GSC review. This contribution represents NRCan contribution number / Numéro de contribution de RNCan: 20220228. We would like to thank Kim Senger and one anonymous reviewer for their constructive feedback.
