An Overview of Tsunami Hazards in the Southwest Pacific Ocean

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...

Mesoscale and Submesoscale Variability in the Indian Ocean

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Material transport and air‐sea coupling dynamics associated with monsoon‐related mesoscale and submesoscale processes in the Indian Ocean significantly modulate biogeochemical cycles, the large‐scale energy balance, and both regional and global climate change.

The Influence of Sea Ice and Ice Mélange on Outlet Glacier Dynamics in the Arctic and Antarctic: Recent Progress and Future Challenges

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Sea ice is situated close to the termini of many outlet glaciers in the Arctic and Antarctic and has the potential to influence their dynamics and, therefore, their contribution to sea level rise. However, the nature, prevalence, and ice‐dynamic significance of sea ice‐glacier interactions remains subject to several open questions.

Multimodel Combination Bathymetry Inversion Approach Based on Geomorphic Segmentation in Coral Reef Habitats Using ICESat-2 and Multispectral Satellite Images

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Owing to the high spatial heterogeneity of substrate types and terrain, the present satellite-derived bathymetry (SDB) methods have low accuracy in deriving large-scale bathymetry in coral reef habitats. Taking 11 coral reefs of Xisha Islands (ocean area

Depth from Satellite Images: Depth Retrieval Using a Stereo and Radiative Transfer-Based Hybrid Method

Remote Sensing, 2018
Satellite imagery is increasingly being used to provide estimates of bathymetry in near-coastal (shallow) areas of the planet, as a more cost-effective alternative to traditional methods.

Analysis and geological interpretation of gravity data from GEOS-3 altimeter [PDF]

A number of detailed gravimetric geoids of portions of the world's oceans from marine gravity measurements were constructed. The geoids were constructed by computing 1 x 1 deg or 10 x 10 deg averages of free-air anomaly data and subtracting these values ...

Assessing the contribution of super-resolution in satellite derived bathymetry in the Antarctic

Estuarine, Coastal and Shelf Science
The difficulty of defining the depth of near-shore seas (bathymetry) arises from the limits imposed by traditional ship-based approaches during data collection. Although LiDAR sensors with green lasers have been used to solve some of these problems, they come at a high cost in terms of their footprint and are prone to inaccuracies in turbid water.

Satellite derived bathymetry using empirical and machine learning approaches: a case study in the highly dynamic coastal water

Coastal Engineering Journal
The estimation of nearshore water depth is essential in many near-shore marine sciences and coastal engineering. However, direct measurements using fieldwork methods can be expensive and time-consuming.

Dynamics of Significant Intraseasonal Variability of Surface Chlorophyll‐a Concentration in the Far Western Tropical Pacific

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract While the far Western Tropical Pacific is known for interannual variability, we find intraseasonal variability (ISV) actually dominates surface chlorophyll (SChl) fluctuations, explaining >30% of variance. The Madden‐Julian Oscillation (MJO) acts as the key driver through three mechanisms: (a) positive MJO phase vertical mixing (enhanced winds
