However, existing hypotheses for the impact of climate variability on sedimentation in these lakes had never been tested. Capitalizing on the predicted El Ni\u00f1o event in 2009, we deployed weather stations and in-lake sondes, as well as simple sediment traps, to test existing hypotheses for sedimentation in these lakes. This work has produced nearly continuous daily data for the climate and limnology of these crater lakes from December 2009 to present, a period that covers more than 7 full seasonal cycles and includes weak, moderate and strong El Ni\u00f1o events and sustained La Ni\u00f1a conditions. Our results to date have prompted a re-thinking of published interpretations of these lake-based climate reconstructions.<\/p>\n<p><a href=\"\/thompsonlab\/files\/2017\/03\/P5142299.jpg\"><img loading=\"lazy\" src=\"\/thompsonlab\/files\/2017\/03\/P5142299-477x636.jpg\" alt=\"OLYMPUS DIGITAL CAMERA\" width=\"284\" height=\"378\" class=\"alignright wp-image-233\" srcset=\"https:\/\/sites.bu.edu\/thompsonlab\/files\/2017\/03\/P5142299-477x636.jpg 477w, https:\/\/sites.bu.edu\/thompsonlab\/files\/2017\/03\/P5142299-768x1024.jpg 768w\" sizes=\"(max-width: 284px) 100vw, 284px\" \/><\/a><\/p>\n<p>Despite the importance of local climate change to the mission of the Charles Darwin Research Station and Gal\u00e1pagos National Park to conserve the unique environment and biodiversity of the archipelago, there is still considerable uncertainty in the sign of the change and its impact on ENSO variability. The long-term monitoring dataset provided by this study has extended data available for making such management decisions. Further, this work will improve reconstructions of the strength and frequency of ENSO events in the past, which will help constrain the range of variability observed in this region.<\/p>\n<p><a href=\"https:\/\/sites.bu.edu\/thompsonlab\/photos\/galapagos\/\">Galapagos Research Photo Gallery<\/a><\/p>\n<h4>Team<\/h4>\n<ul>\n<li><a href=\"http:\/\/research3.fit.edu\/paleolab\/\" target=\"_blank\">Dr. Mark Bush<\/a>, Florida Institute of Technology<\/li>\n<li><a href=\"https:\/\/sites.google.com\/site\/chappazlab\/\" target=\"_blank\">Dr. Anthony\u00a0<\/a><span>Chappaz, Central Michigan University<\/span><\/li>\n<li><a href=\"https:\/\/sites.google.com\/site\/jcoleazgeo\/home\" target=\"_blank\">Dr. Julia Cole<\/a>, University of Arizona<\/li>\n<li>Dr. Aaron Collins, Florida Institute of Technology<\/li>\n<li><a href=\"https:\/\/publish.illinois.edu\/jconro\/\" target=\"_blank\">Dr. Jessica Conroy<\/a>, University of Illinois\u00a0<span>at Urbana-Champaign<\/span><\/li>\n<li>Stephan\u00a0<span>Hlohowskyj, Graduate Student, Central Michigan University<\/span><\/li>\n<li><a href=\"http:\/\/www.bu.edu\/earth\/people\/faculty\/andrew-c-kurtz\/\" target=\"_blank\">Dr. Andy Kurtz<\/a>, Boston University<\/li>\n<li>Dr. Jonathan Overpeck, University of Arizona<\/li>\n<li><a href=\"https:\/\/www.cmich.edu\/colleges\/cst\/earth_atmos\/Pages\/Megan-Rohrssen.aspx\" target=\"_blank\">Dr. Megan\u00a0Rohrssen<\/a><span>, Central Michigan University<\/span><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>The sediment records from Genovesa and Bainbridge Crater Lakes, Galapagos have provided long records of past changes in tropical Pacific climate variability, particularly variability associated with the El Ni\u00f1o-Southern Oscillation (ENSO).
