Balanced to Unbalanced Motions at a Submesoscale Front and Energy Transfer From Eddy Splitting

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Submesoscale dynamics play a crucial role in energy redistribution in the upper ocean but remain challenging to observe due to their small spatial and temporal scales. We use ship‐based observations of an oceanic submesoscale front sampled at high resolution while repeatedly traversed to observe deformation and splitting of an embedded ...

Dissipative inertial transport patterns near coherent Lagrangian eddies in the ocean

, 2015
Recent developments in dynamical systems theory have revealed long-lived and coherent Lagrangian (i.e., material) eddies in incompressible, satellite-derived surface ocean velocity fields.

2023–2027 CAP First Pillar Reform and Livestock Sector: Production and Economic Impacts on Italian Specialized Dairy Cattle Farms

Applied Economic Perspectives and Policy, Volume 48, Issue 2, Page 382-396, May 2026.
ABSTRACTThe present study uses an agroeconomic supply model to assess the impacts of 2023–2027 CAP on Italian specialized dairy cattle farms. The model considers the voluntary choice of Eco‐Scheme 1, specifically addressed to livestock farms, through the implementation of binary variables.

Detection of Equatorial Plasma Bubbles Using the COSMIC‐2 Rate of TEC Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Equatorial plasma bubbles (EPBs) are large‐scale plasma depletion structures that can disrupt Global Navigation Satellite Systems (GNSS) and other space‐based technologies. Several instruments have been employed to study EPB dynamics, with Total Electron Content (TEC) and Rate of TEC change Index (ROTI) data standing out as valuable parameters

The Eddy Experiment: accurate GNSS-R ocean altimetry from low altitude aircraft

, 2004
During the Eddy Experiment, two synchronous GPS receivers were flown at 1 km altitude to collect L1 signals and their reflections from the sea surface for assessment of altimetric precision and accuracy.

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.

Influx of Bay of Bengal Waters and Stirring Trends in the Arabian Sea Based on Satellite Altimetry

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Freshwater transport and stirring affect air–sea interactions in the Arabian Sea (AS). Using three decades of satellite‐based surface currents, this study examines (a) the volume influx of water masses into southeastern AS from the Bay of Bengal (BoB), and (b) horizontal stirring over seasonal to interannual timescales in the AS.

SWOT and Swath Altimetry: A Breakthrough for Global Ocean Prediction

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Since its launch in December 2022, the SWOT (Surface Water and Ocean Topography) satellite with its KaRIn (Ka‐band interferometer) instrument has provided unprecedented, high‐resolution, two‐dimensional views of global Sea Surface Height (SSH), offering crucial insights into ocean dynamics.
