Hot off the Press! Tiny fossils reveal a major sea-level fall into the Last Glacial Maximum

Please join me in congratulating Prof. Kazuhiko Fujita and colleagues on their new paper in Earth and Planetary Science Letters, which uses fossil foraminifera recovered during IODP Expedition 325 Great Barrier Reef Environmental Changes to reconstruct global mean sea level from late Marine Isotope Stage 3 into the Last Glacial Maximum. Fujita, K., Nakada, C., Yagioka, N., Miyairi, Y., Humblet, M., Kan, H., Iryu, Y., Webster, J....

Hot off the Press: Revealing 7,200 Years of Reef Change in Indonesia’s Coral Triangle

Please join me in congratulating the newly “minted” Dr Mike Hynes on the publication of his exciting new paper just published in Coral Reefs. This paper provides a rare long-term perspective on how coral reef communities have changed through time in Indonesia's Spermonde Archipelago, one of the world's most biodiverse reef systems. Hynes, M. G., Parenden, D., Ke, S., Spanowicz, K., Masdar, H., Putra, S....
