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 ...

Satellite techniques for determining the geopotential for sea-surface elevations [PDF]

, 1984
Spaceborne altimetry with measurement accuracies of a few centimeters which has the potential to determine sea surface elevations necessary to compute accurate three-dimensonal geostrophic currents from traditional hydrographic observation is discussed ...

Strategic Roadmap for Addressing Microplastic Pollution in the Global South: Bridging Monitoring Gaps, Harmonizing Methods, and Building Analytical Capacity

Environmental Quality Management, Volume 35, Issue 4, Summer 2026.
ABSTRACT Microplastic (MP) pollution represents a growing environmental challenge, especially in tropical and subtropical coastal regions of the Global South, where methodological fragmentation, funding discontinuity, and dependence on external analytical infrastructure limit the production of comparable data and the formulation of evidence‐based ...

Analysis of Precise Orbit Determination for the HY2D Satellite Using Onboard GPS/BDS Observations

Remote Sensing, 2022
High-precision orbits of Low Earth Orbit (LEO) satellites are essential for many scientific applications, such as assessing the change in current global mean sea level, estimating the coefficients of gravity field, and so on.

Tidal Correlation using Altimetry Satellite

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Tides data is strongly needed especially on Indonesian Coastal Environment mapping to achieve its accuracy. Usually, tides data derived from direct or indirect measurement. From palm observation, the tides data collected directly.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

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.

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 ...
