Soil Remains Warmer and Drier After Long-term Warming Stops

by W. M. Hammond 23 July 202022 March 2023

Pausing a long-term soil warming experiment revealed that previously warmed plots remained both warmer and drier compared to plots which had not experienced previous soil warming.

Estuary Research Suffers from Scientific Bias

Kate Wheeling, freelance science writer by Kate Wheeling 17 July 202010 February 2022

Researchers are calling for a closer look at nutrient cycling in tropical and low-nutrient estuaries, which have long been overlooked in the scientific literature.

Two researchers look on as a water-sampling device hangs over the side of a research vessel during a cruise to study nitrous oxide emissions.
