About

Braddock Linsley is a Lamont Research Professor and the Director of the Lamont-Doherty Stable Isotope and Trace Element Laboratory at Columbia University. He joined Lamont in 2011 after spending 16 years as a Professor in the Department of Atmospheric and Environmental Sciences at the University at Albany-SUNY. His research focuses on paleoceanography, utilizing marine sediment cores and coral records to study past oceanographic and climate conditions. Dr. Linsley's work has significantly advanced understanding of interannual to multidecadal climate dynamics and millennial-scale variability in the ocean. His paleoclimate research has taken him to remote sites across the Pacific, including sediment and coral cores from locations such as Panamá, Clipperton Atoll, Fanning Atoll, Rarotonga, Fiji, Tonga, Samoa, the Great Barrier Reef, the Makassar Strait in Indonesia, the Sulu Sea, and the New Guinea margin. He teaches courses on Monitoring and Analysis of Marine and Estuary Systems and Stable Isotope Geochemistry at Columbia University.

  Abstract Mass coral bleaching on the Great Barrier Reef (GBR) in Australia between 2016 and 2024 was driven by high sea surface temperatures (SST) 1 . The likelihood of temperature-induced bleaching is a key determinant for the future threat status of the GBR 2 , but the long-term context of recent temperatures in the region is unclear. Here we show that the January–March Coral Sea heat extremes in 2024, 2017 and 2020 (in order of descending mean SST anomalies) were the warmest in 400 years, exc…

  Abstract Global mean sea level (GMSL) during intermediate interglacial Marine Isotope Stage 3 (MIS 3) (60–26 ka) has proven difficult to constrain. Paleo‐sea level estimates based on ice margin, modeling, and paleo‐shoreline reconstructions indicate that MIS 3 GMSL was substantially higher than reconstructed from deep‐ocean benthic foraminifera oxygen isotope (δ 18 O) and coral records, implying much smaller ice sheets during MIS 3. Here, we use the δ 18 O and Mg/Ca chemistry of surface and ther…

  Abstract The Great Barrier Reef (GBR) is an internationally recognized and widely studied ecosystem, yet little is known about its sea surface temperature (SST) evolution since the Last Glacial Maximum (LGM) (~20 kyr BP). Here, we present the first paleo‐application of Isopora coral‐derived SST calibrations to a suite of 25 previously published fossil Isopora from the central GBR spanning ~25–11 kyr BP. The resultant multicoral Sr/Ca‐ and δ 18 O‐derived SST anomaly (SSTA) histories are placed wi…
