Effects of Mesoscale Eddies on Acoustic Propagation with Preliminary Analysis of Topographic Influences

Journal of Marine Science and Engineering
This study investigates underwater acoustic propagation patterns under mesoscale eddy conditions through numerical modeling and parametric analysis. A mathematical model of mesoscale eddies was developed, and acoustic transmission loss was computed using

A Strictly Geostrophic Product of Sea‐Surface Velocities From the SWOT Fast‐Sampling Phase

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract While geostrophy remains the simplest and most practical balance to extract velocity information from sea‐surface height anomaly (SSHa), confusions remain within the oceanographic community to what extent this balance can be applied to altimetric observations with the launch of the Surface Water and Ocean Topography (SWOT) satellite. Given the

Double‐ITCZ Bias Reduces Southern Hemisphere Influence on Tropics via Oceanic Pathways

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Many coupled climate models exhibit an Intertropical Convergence Zone (ITCZ) south of the Equator in the annual‐mean tropical Pacific that is more pronounced than observed. This bias impacts winds, wind‐driven ocean circulation, including the meridional subtropical cells, and the zonal distribution of waters supplying the equatorial ...

The Complete Life Cycle of Dark Spot NDS‐2018 on Neptune

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Hubble Space Telescope collected imaging data spanning the full lifetime of Neptune's dark spot NDS‐2018, which is the sixth large, persistent dark spot seen in the planet's atmosphere. Neptune's dark spots are thought to be anticyclonic vortices, although internal flows have never been directly measured to confirm their rotation. Previous

Solar‐Cycle Modulation of Subsurface Ocean Memory via the North Pacific Eastern Subtropical Mode Water

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The North Pacific eastern subtropical mode water (NPESTMW) connects the subtropics and tropics, influencing climate variability on interannual to decadal timescales. Using eight decades of ocean reanalysis, we show that the 11‐year solar‐cycle robustly modulates NPESTMW volume. NPESTMW formation is suppressed 1–2 years after solar maxima: high

Earlier Timing of the Annual Deepest Mixed Layer and Phytoplankton Bloom North of the Kuroshio Extension After the 2010s

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The deep winter mixed layer in the Kuroshio Extension (KE) region is important for the climate and ecosystems, yet its spatiotemporal variations and ecological impacts under pronounced ocean warming remain uncertain. Based on multiple observational and reanalysis data sets from 1980 to 2025, we find a pronounced shoaling (∼40 m) of the mixed ...

Temporal Heterogeneity of In Situ Ocean Observing Capacity Could Cause an Artificial Intensification of Extreme Warm Water Events Globally

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Extreme warm events in the ocean, known as marine heatwaves (MHWs), can have severe and even irreversible impacts on marine ecosystems, underscoring the imperative need to quantify their anthropogenic changes based on observations. In situ temperature profiles over the past three decades reveal an outsized global increase (over 10% per decade)

Assessing Dynamical Contributions to SWOT Sea Surface Height in an Internal Tide Hotspot

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission has revealed high‐frequency sea surface height anomaly (SSHA) variability associated with internal gravity waves, yet comparison with in situ observations remains limited. Here, we analyze a mooring array beneath the swaths of SWOT Cal/Val south of New Caledonia, an internal tide (IT ...
