A study in JGR Earth Surface examines the link between Hurricane María and sediment mobilization by landslides in Puerto Rico.

Krystal Vasquez describes chemical ionization mass spectrometry (CIMS) and its use in atmospheric chemistry.

Mónica Ramírez-Calderón outlines the use of fission track dating to provide constraints on the break up of the Pangea supercontinent

Submarine groundwater discharge transports nutrients from terrestrial to marine systems, but is often ignored in coastal biogeochemistry. In this Review, the fluxes, impacts and management implications of this discharge are examined and compared with riverine fluxes globally.

Successful discovery and operation of geothermal resources requires a thorough understanding of the heterogeneous geological subsurface. This Review discusses the key geological factors that contribute to the effective exploration of intermediate-temperature to high-temperature geothermal resources used for power generation and direct use applications.

Initialized climate predictions offer distinct benefits for multiple stakeholders. This Review discusses initialized prediction on subseasonal to seasonal (S2S), seasonal to interannual (S2I) and seasonal to decadal (S2D) timescales, highlighting potential for skilful predictions in the years to come.

Repeated amalgamation and dispersal of continents over Earth history is known as the supercontinent cycle; however, the geodynamic processes driving this cyclicity remain debated. This Review synthesizes observations, plate reconstructions and geodynamic models of supercontinent, and older Archaean supercraton, cycles.
