Description
The authors derived alkenone-based spring/summer sea-surface temperatures (SSTs) from a marine sedimentary record obtained from Jacaf Fjord in northern Chilean Patagonia (44°20.00'S, 72°58.15'W) that spanned the last 1750 years; and in doing so they observed two different regimes of climate variability in their record: "a relatively dry/warm period before 900 cal yr BP (higher runoff and average SST 1°C warmer than present day) and a wet/cold period after 750 cal yr BP (higher runoff and average SST 1°C colder than present day)," which they associated with the Medieval Warm Period and Little Ice Age, respectively.
