      Dansgaard‐Oeschger (D‐O) climate instabilities that took place during Marine Isotope Stage 3 are connected to changes in ocean circulation patterns and sea ice cover. Here we explore in detail the configuration of the water ...
    • Insolation and Glacial Meltwater Influence on Sea‐Ice and Circulation Variability in the Northeastern Labrador Sea During the Last Glacial Period 

      Griem, Lisa; Voelker, Antje H.L.; Berben, Sarah Miche Patricia; Dokken, Trond Martin; Jansen, Eystein (Journal article; Peer reviewed, 2019)
      The variable amounts of ice rafted debris (IRD) and foraminifers in North Atlantic sediments are related to the abrupt, millennial‐scale alteration from Greenland stadials to interstadials during the last glacial period ...
    • PaCTS 1.0: a crowdsourced reporting standard for paleoclimate data 

      Khider, Deborah; Emile-Geay, Julien; McKay, Nicholas P.; Gil, Yolanda; Garijo, Daniel; Ratnakar, Varun; Alonso-Garcia, Montserrat; Bertrand, Sebastien; Bothe, Oliver; Brewer, Peter; Bunn, Andrew G.; Chevalier, Manuel; Comas-Bru, Laia; Csank, Adam; Dassié, Emilie; DeLong, Kristine L.; Felis, Thomas; Francus, Pierre; Frappier, Amy; Gray, William R.; Goring, Simon; Jonkers, Lukas; Kahle, Michael; Kaufman, Darrell S.; Kehrwald, Natalie M.; Martrat, Belen; McGregor, Helen V; Richey, Julie; Schmittner, Andreas; Scroxton, Nick; Sutherland, Elaine K.; Thirumalai, Kaustubh; Allen, Kathryn J.; Arnaud, Fabien; Axford, Yarrow; Barrows, Timothy T.; Bazin, Lucie; Pilaar Birch, Suzanne E.; Bradley, Elizabeth; Bregy, Joshua; Capron, Emilie; Cartapanis, Olivier; Chiang, Hong-Wei; Cobb, Kim M.; Debret, Maxime; Dommain, René; Du, Jianghui; Dyez, Kelsey A.; Emerick, Suellyn; Erb, Michael P.; Falster, Georgina; Finsinger, Walter; Fortier, Daniel; Gauthier, Nicholas; George, Steve; Grimm, Eric C.; Hertzberg, Jennifer; Hibbert, Fiona D.; Hillman, Aubrey; Hobbs, William R; Huber, Matthew; Hughes, Anna L.C.; Jaccard, Samuel L.; Ruan, Jiaoyang; Kienast, Markus; Konecky, Bronwen; Le Roux, Gael; Lyubchich, Vyacheslav; Novello, Valdir F.; Olaka, Lydia; Partin, Judson; Pearce, Christof; Phipps, Steven J.; Pignol, Cecile; Piotrowska, Natalia; Poli, Maria-Serena; Prokopenko, Alexander; Schwank, Franciele; Stepanek, Christian; Swann, George E.A.; Telford, Richard; Thomas, Elizabeth R.; Thomas, Zoe; Truebe, Sarah; Von Gunten, Lucien; Waite, Amanda J.; Weitzel, Nils; Wilhelm, Bruno; Williams, John W.; Williams, Joseph J.; Winstrup, Mai; Zhao, Ning; Zhou, Yuxin (Journal article; Peer reviewed, 2019-09)
      The progress of science is tied to the standardization of measurements, instruments, and data. This is especially true in the Big Data age, where analyzing large data volumes critically hinges on the data being standardized. ...
    • Precessional Cyclicity of Seawater Pb Isotopes in the Late Miocene Mediterranean 

      Modestou, Sevasti Eleni; Gutjahr, Marcus; van der Schee, Marlies; Ellam, Rob; Flecker, Rachel (Peer reviewed; Journal article, 2019-12)
      Astronomical tuning in the Mediterranean region is primarily based on organically‐mediated proxies, such as cyclicity of organic rich layers or changes in foraminiferal assemblages. Both during and post deposition, organic ...
