The decay of radioactive elements—like U, Th and K—produces heat and the dissipation of this heat from Earth's interior drives mantle convection and plate tectonics. Significant portions of Earth’s heating-producing elements (HPEs) are proposed to be sequestered within the continental crust, yet the HPE budget of the crust is uncertain, with…

Group discussion for upcoming meeting with the dean.
The discovery of an enrichment of the element iridium (Ir) in a clay layer marking the Cretaceous-Paleogene (K-Pg) boundary led to the meteorite impact theory for the end-Cretaceous extinction. This theory has been corroborated by much subsequent evidence including recognition of the Chicxulub crater as the point of impact. What could possibly…

Ocean warming is considered the most severe threat to coral reefs. Increasing duration and frequency of marine heat waves over the last few decades have led to large-scale coral bleaching and death, and hence the loss of diverse and productive coral reefs around the world. However, not all corals are equally susceptible to heat stress and it is…

Magnetic fields are thought to govern the dynamics of protoplanetary disks by mediating inward gas accretion and, possibly, setting up turbulent concentrations of dust to form the first planetesimals. A subset of these planetesimals then accrete to form rocky planets, which may eventually host magnetic core dynamos and mobile-lid plate…

The upward trend in atmospheric carbon dioxide is accompanied by a trend in the carbonate system, oxygen concentrations, and temperatures of the global ocean, but in coastal environments, local and regional processes can modulate or exacerbate these trends. Coastal and regional processes can occur on spatial scales that are not well represented…
