A 10-month gas-hydrate production test on Alaska’s North Slope produced gas at a stable rate for 60 days. But pump failures and problems with the system meant to keep sand out of the well limited depressurization and productivity, providing design lessons for future tests.
Sediments from Lakes Bolshoye Miassovo and Maloye Miassovo in Russia’s Southern Urals contain evidence of several past warming, cooling and drying events. The researchers linked changes in the sediments to regional and global climate stages, including a warming about 14,700 years ago and later dry periods.
The 2024 Noto Peninsula Earthquake triggered large sediment flows in Toyama Bay, carrying organic-rich material into the deep sea. The following decomposition was associated with lower oxygen and higher nutrient concentrations, while low-oxygen conditions persisted for at least 152 days.
