Hamilton's principle for quasigeostrophic motion

, 1998
We show that the equation of quasigeostrophic (QG) potential vorticity conservation in geophysical fluid dynamics follows from Hamilton's principle for stationary variations of an action for geodesic motion in the f-plane case or its prolongation in the ...

Climate Change Projections for the Southwest Pacific Ocean Using Coupled Model Intercomparison Project (CMIP) Phase 5 and 6 Models: Implications for Physics, Biogeochemistry, Ecosystems, and Fisheries

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
This article analyses future projections of ocean properties for a region of the south‐west Pacific Ocean encompassing the New Zealand Exclusive Economic Zone under different climate change emission scenarios. Projections are updated and expanded from previous assessments using a “best” ensemble comprising both CMIP5 and CMIP6 earth system models.

Oceanographic conditions over the continental shelf off Magdalena Bay (Mexico) in 2011–2012

Ciencias Marinas, 2014
The hydrophysical results obtained during six oceanographic cruises in 2011 (February, April, July, and October) and 2012 (February and April) over a 50-station sampling grid in front of the Magdalena-Almejas lagoon system (Mexico) are presented.

An Alternative Way to Parameterizing the Nonlocal Scale Sensible Heat Flux Using the Flux Imbalance and K‐Theory Approach

Journal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Accurately representing the surface sensible heat flux (SHF) in Earth System Models (ESMs) is of paramount importance and challenge. This study introduces an alternative surface‐layer SHF correction scheme by modeling nonlocal scale SHF through flux imbalance (FI) prediction models while employing the conventional gradient diffusion approach ...

Response of the thermohaline front and associated submesoscale features in the Korea Strait to wind variation during autumn

Frontiers in Marine Science
In the present study, a three-dimensional numerical simulation with a 1 km grid spacing is conducted to investigate the response of the thermohaline front in the northern Korea Strait (KS) and its associated submesoscale features to wind variation.

Reconstruction of Core‐Surface Flows During the Last 3,300 Years

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Understanding the Earth's magnetic field evolution requires examining the fluid flow at the core‐mantle boundary that drives the changes over different timescales. The inversion process to derive core‐surface flow velocities from secular variation data encounters non‐uniqueness issues, necessitating a priori assumptions that yield different ...

Intense Isopycnal Stirring and Double‐Diffusion Contributing to Microscale Variance in the Kuroshio Extension Front

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract In oceanic frontal regions, isopycnal stirring induces lateral thermohaline intrusion. Previous studies have observed interleaving layers in the Izu Ridge and Kuroshio Extension attributed to isopycnal stirring driven by mesoscale eddies and submesoscale flows.

Survey of El Nino 1957-58 in its relation to tropical pacific meteorology [PDF]

, 1966
ENGLISH: The survey aims at demonstrating the close relationship between anomalies of sea temperature observed along the tropical Pacific coast of the Americas and those observed in the oceanwide tropical belt. The survey also covers the variations, from

Synoptic Controls of Extreme Ice Area Flux Events Along Nares Strait

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Nares Strait, the channel between Ellesmere Island and northwest Greenland, connects the Arctic Ocean's Lincoln Sea to northern Baffin Bay. The transport of thick, multi‐year sea ice southward down the Strait contributes to the overall loss of this important ice class from the Arctic.

Near‐Inertial Wave Trapping Inside a Fine‐Scale Anticyclonic Eddy During the BioSWOT‐Med 2023 Cruise: Turbulence and Energy Flux

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Near‐inertial waves (NIWs) are an important source of turbulence for the ocean interior. Mesoscale anticyclonic eddies are known to facilitate their propagation at depth while trapping them. However, in situ observations have so far focused on large (>50 ${ >} 50$ km radius), energetic eddies, whereas most of the ocean is populated by smaller,
