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.

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.

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 ...

A Complete Formula of Ocean Surface Absolute Geostrophic Current.

Scientific reports, 2020
Absolute geostrophic current at the ocean surface (S) contains three components: (1) absolute geostrophic current at the geoid undulation (N), (2) geostrophic shear (between S and N) due to horizontal gradient of dynamic ocean topography, and (3) geostrophic shear (between S and N) due to horizontal gradient of density.

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 ...

Numerical Simulation of Fluid Flow in the Narrow Strait with Density Differences

JTAM (Jurnal Teori dan Aplikasi Matematika)
This study investigates the dynamics of fluid flow through a narrow strait connecting two large water bodies with different densities using numerical simulations. The research focuses on understanding how density-driven currents develop and interact in a

A review of the role of submarine canyons in deep-ocean exchange with the shelf [PDF]

Ocean Science, 2009
Cross shelf-break exchange is limited by the tendency of geostrophic flow to follow bathymetric contours, not cross them. However, small scale topography, such as canyons, can reduce the local lengthscale of the flow and increase the local Rossby number.

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.

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.
