    In:  Supplement to: O'Beirne, Molly D; Werne, Josef P; Hecky, Robert E; Johnson, Thomas C; Katsev, Sergei; Reavie, Euan D (2017): Anthropogenic climate change has altered primary productivity in Lake Superior. Nature Communications, 8, 15713, https://doi.org/10.1038/ncomms15713
    Publication Date: 2023-10-07
    Description: Anthropogenic climate change has the potential to alter many facets of Earth's freshwater resources, especially lacustrine ecosystems. The effects of anthropogenic changes in Lake Superior, which is Earth's largest freshwater lake by area, are not well documented (spatially or temporally) and predicted future states in response to climate change vary. Here we show that Lake Superior experienced a slow, steady increase in production throughout the Holocene using (paleo)productivity proxies in lacustrine sediments to reconstruct past changes in primary production. Furthermore, data from the last century indicate a rapid increase in primary production, which we attribute to increasing surface water temperatures and longer seasonal stratification related to longer ice-free periods in Lake Superior due to anthropogenic climate warming. These observations demonstrate that anthropogenic effects have become a prominent influence on one of Earth's largest, most pristine lacustrine ecosystems.

Scripps Institution of Oceanography Reference Series, 74-22, 39 pp, https://www.ngdc.noaa.gov/mgg/curator/data/argo/scan/scan_expedition_report.pdf
    Publication Date: 2023-10-07
    Description: The cores described on the following pages were obtained on the Scripps Institution of Oceanography SCAN Expedition during March 1969 to February 1970 aboard R/V Argo. The primary purpose of the expedition was to conduct geological surveys of prospective drilling sites for the Deep Sea Drilling Project. A total of 106 locations in the Pacific Ocean were geologically sampled, usually by coring but, on occasion, by dredging. The following descriptions are of all the cores taken on SCAN which are available at Scripps for sampling and study.
