A multiproxy database of western North American Holocene paleoclimate records

Abstract

Abstract. Holocene climate reconstructions are useful for understanding the diverse\nfeatures and spatial heterogeneity of past and future climate change. Here\nwe present a database of western North American Holocene paleoclimate\nrecords. The database gathers paleoclimate time series from 184 terrestrial\nand marine sites, including 381 individual proxy records. The records span\nat least 4000 of the last 12\u2009000\xa0years (median duration of\xa010\u2009725\xa0years)\nand have been screened for resolution, chronologic control, and climate\nsensitivity. Records were included that reflect temperature, hydroclimate,\nor circulation features. The database is shared in the machine readable\nLinked Paleo Data (LiPD) format and includes geochronologic data for\ngenerating site-level time-uncertain ensembles. This publicly accessible and\ncurated collection of proxy paleoclimate records will have wide research\napplications, including, for example, investigations of the primary features\nof ocean–atmospheric circulation along the eastern margin of the North\nPacific and the latitudinal response of climate to orbital changes. The\ndatabase is available for download at https://doi.org/10.6084/m9.figshare.12863843.v1 (Routson and McKay, 2020).
