Geologists around the world hailed the June 2023 news that a scientific expedition to the mid-Atlantic Ridge succeeded in collecting samples of Earth’s mantle from the ocean floor. The breakthrough fulfilled a nearly century-old dream to reach Earth’s mantle, which holds essential clues about Earth’s age, makeup, and internal processes. In 1957, NAS member Walter Munk had proposed “Project Mohole”, an attempt to drill through a couple of miles of Earth’s crust at the Mohorovicic Discontinuity, or Moho, but the project never reached that goal. The 2023 expedition aboard the drill ship JOIDES Resolution succeeded by finding a “tectonic window” in the middle of the Atlantic Ocean where the mantle is just about a mile beneath the ocean floor. Many reports from the National Academies have explored the need for, value of, and technical challenges of scientific ocean drilling. As always, those reports are free to read online or download.

The ocean is an integral component of the Earth’s climate system. It covers about 70% of the Earth’s surface and acts as its primary reservoir of heat and carbon, absorbing over 90% of the surplus heat and about 30% of the carbon dioxide associated with human activities, and receiving close to 100% of fresh water lost from land ice.
The sea ice surrounding Antarctica has increased in extent and concentration from the late 1970s, when satellite-based measurements began, until 2015. Although this increasing trend is modest, it is surprising given the overall warming of the global climate and the region. Indeed, climate models, which incorporate our best understanding of the …[more]

Tuesday the presidential panel investigating the Gulf of Mexico oil spill released its final report, analyzing problems that led to the incident and making recommendations for new regulations to prevent a similar disaster. The National Research Council, National Academy of Engineering, and the Institute of Medicine have produced a number of reports that discuss causes of the oil spill and its effects on human health.
Interim Report on Causes of the Deepwater Horizon Oil Rig Blowout and Ways to Prevent Such Events examines the probable causes of the Deepwater Horizon explosion, fire, and oil spill and identifies measures for preventing similar harm in the future. The book addresses the performance of technologies and practices involved in the probable causes of the Macondo well blowout and explosion on the Deepwater Horizon. It also explores industry best practices and standards, and identifies and recommends available technologies and measures that can ensure a higher level of safety in deepwater exploratory drilling and well completion.
