The Science We Need to Assess Marine Carbon Dioxide Removal

by Jaime B. Palter, Jessica Cross, Matthew C. Long, Patrick A. Rafter and Clare E. Reimers 1 June 202325 January 2024

As companies begin selling credits for marine carbon dioxide removal in largely unregulated marketplaces, scientists must develop standards for assessing the effectiveness of removal methods.

Engineering with Nature to Face Down Hurricane Hazards

by Krystyna Powell, Safra Altman and James Marshall Shepherd 5 January 202327 March 2023

Natural and engineered, nature-based structures offer promise for storm-related disaster risk reduction and flood mitigation, as long as researchers can adequately monitor and study them.

On the right is the first stratigraphic section of the Grand Canyon, from Powell’s 1875 report, showing what would later be termed the Great Unconformity. A is the metamorphic basement—the oldest rocks that have been contorted. B is the Precambrian Grand Canyon Supergroup, which is composed of tilted sedimentary rocks that lack fossil assemblages. C indicates flat-lying Paleozoic rocks, which contain fossils marking the explosion of life. Two unconformities can be seen at x and y, with the former marking the Great Unconformity. The image on the left is a recent photograph of the Grand Canyon from Walhalla Plateau, with the red line showing the Great Unconformity. Blue lines trace the tilted layers below the famed surface, and yellow lines trace the flat-lying sedimentary rocks on top.

The Great Unconformity or Great Unconformities?

by Alka Tripathy-Lang 23 December 202231 January 2023

Some scientists think the Great Unconformity was caused by Snowball Earth’s glaciations. Recent work suggests these phenomena might not be related.
