Multi‐Elemental Tracers in the Amerasian Basin Reveal Interlinked Biogeochemical and Physical Processes in the Arctic Ocean Upper Halocline

Global Biogeochemical Cycles, Volume 39, Issue 4, April 2025.
Abstract The physical and biogeochemical properties of the western Arctic Ocean are rapidly changing, resulting in cascading shifts to the local ecosystems. The nutrient‐rich Pacific water inflow to the Arctic through the Bering Strait is modified on the Chukchi and East Siberian shelves by brine rejection during sea ice formation, resulting in a ...

Ionospheric D Region: Characteristics Near Dawn and Dusk

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract The characteristics of very low frequency (VLF) radio wave propagation in the Earth‐ionosphere waveguide are determined particularly through dawn and dusk using phase and amplitude measurements of man‐made signals propagating below the ionospheric D region. For the first time variations of “Wait” height and sharpness parameters, H' and β, have

The Rise and Fall of Marpha Lake, a Late Quaternary Dammed Lake in the Himalayan Rain‐Shadow With Implications to Landscape Evolution and Sediment Dynamics

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 4, April 2025.
Abstract Understanding landscape evolution history and sedimentary dynamics in high mountainous regions is tampered by rapid erosion of the sedimentary archives. Naturally dammed lakes provide unique snapshots of these processes and enable evaluating these processes under climatic conditions different from the present.

Correlation Between the Delay and Rise Time of VLF/LF Amplitudes During 20 Solar X‐Ray Flares Observed in February 2014 at Mid‐Latitude

Radio Science, Volume 60, Issue 4, April 2025.
Abstract During daylight hours, the concentration of electrons in the ionosphere can be amplified by solar flares, which may subsequently influence the propagation of radio waves. Previous research on Very Low Frequency (VLF) signals focused on X‐class and M‐class flares.
