Next Generation 7 Tesla Arterial Spin Labeling With Rotated Spiral Acquisition Enables Mesoscale Resolution in 3D Brain Perfusion and Functional MRI

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2702-2717, May 2026.
ABSTRACT Purpose To achieve high resolution (≤ 1 mm isotropic) whole‐brain perfusion imaging at 7 T with next generation ASL pulse sequence, reconstruction algorithm, and MRI hardware. Methods We capitalized on three major innovations: (1) FLASH‐based pseudo‐Continuous ASL (pCASL) sequence with rotated golden‐angle stack‐of‐spirals (rGA‐SoS) sampling; (

Isopycnal Submesoscale Stirring Crucially Sustaining Subsurface Chlorophyll Maximum in Ocean Cyclonic Eddies

Geophysical Research Letters
Mesoscale and submesoscale processes have crucial impacts on ocean biogeochemistry, importantly enhancing the primary production in nutrient‐deficient ocean regions. Yet, the intricate biophysical interplay still holds mysteries.

Characterising global ocean mesoscale eddy by AVISO and Haiyang-2 altimeter

International Journal of Digital Earth
This work compares the Haiyang-2 (HY-2) altimeter data with the well-recognized satellite oceanographic data (AVISO) product in the global ocean in their capability of detecting mesoscale eddy. A well-established method to detect mesoscale eddies from HY-

Projected Future of African Marine Ecosystems Under Climate Change and Stratospheric Aerosol Injection

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Stratospheric Aerosol Injection (SAI) has been proposed as a potential strategy to cool the planet. The ARISE‐SAI‐1.5 approach, which employes a moderate emission scenario, is simulated to limit future global warming to 1.5°C by injecting aerosols into the stratosphere in the year 2035.

A Machine Learning Parameterization for the Internal Gravity Wave Spectrum

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract We introduce a stochastic model designed to parametrize the spectral properties of internal waves, using two functions that represent the semidiurnal spectral tidal cusps and the energy continuum between the inertial and the buoyancy frequencies.

Autonomous Float Data Reveal Decoupled Trends in Chlorophyll and Stratification in the Indian Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Recent studies have shown that the Indian Ocean is warming significantly, but how this warming impacts primary production is largely unresolved due to a relative lack of depth‐resolved biological observations. In this study, we have used Biogeochemical‐Argo data from 2013 to 2022, comprising over 9,000 individual profiles, to examine regional ...
