The Lake Petén Itzá Scientifi c Drilling Project
Polar ice cores provide us with high-resolution records of past climate change at high latitudes on both glacial-to-interglacial and millennial timescales. Paleoclimatologists and climate modelers have focused increasingly on the tropics, however, as a potentially important driver of global climate change because of the region’s role in controlling the Earth’s energy budget and in regulating th...
متن کاملLake Bosumtwi Drilling Project: Shock Metamorphism in Rocks from Core
General context: Shock barometry via petrographic analysis helps to understand cratering mechanics, especially mass movements in the central uplift, including its collapse in the late stage of cratering. Shock pressures recorded in lithologies of the central uplift may exceed 45 GPa, e.g., in the Vorotilovo core drilled into the center of the Puchezh-Katunki structure [1]. In other craters, sho...
متن کاملThe Lake El’gygytgyn Scientific Drilling Project – Conquering Arctic Challenges through Continental Drilling
Between October 2008 and May 2009, the International Continental Scientific Drilling Program (ICDP) co-sponsored a campaign at Lake El ́gygytgyn, located in a 3.6-Ma-old meteorite impact crater in northeastern Siberia. Drilling targets included three holes in the center of the 170-m-deep lake, utilizing the lake ice cover as a drilling platform, plus one hole close to the shore in the western la...

متن کاملExploratory Hydrocarbon Drilling Impacts to Arctic Lake Ecosystems
Recent attention regarding the impacts of oil and gas development and exploitation has focused on the unintentional release of hydrocarbons into the environment, whilst the potential negative effects of other possible avenues of environmental contamination are less well documented. In the hydrocarbon-rich and ecologically sensitive Mackenzie Delta region (NT, Canada), saline wastes associated w...
