Drivers of Basal Melt Variability for Pine Island Glacier Ice Shelf: Ocean Forcing Versus Geometric Feedback

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Since the 1970s, Pine Island Glacier has exhibited thinning, acceleration, and retreat. During the last decade, the ice shelf has undergone major geometric changes, whilst the quantity and temperature of modified Circumpolar Deep Water on the Amundsen Sea continental shelf fluctuated significantly.

Impact of Turbidity on Satellite-Derived Bathymetry: Comparative Analysis Across Seven Ports in the South China Sea

Remote Sensing
This study investigates the uncertainty of satellite-derived bathymetry (SDB) in turbid port environments by integrating multi-temporal composites of Sentinel-2 and Landsat 8 satellite imagery with in situ bathymetry and turbidity data. The research aims

Internal Wave Characteristics in the Andaman Sea: New Insights From SWOT Observations

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract High‐resolution, repeat‐pass Sea Surface Height Anomaly (SSHA) observations from the Surface Water and Ocean Topography (SWOT) satellite are used to investigate Internal Solitary Waves (ISW) in the Andaman Sea over a one‐year period starting in July 2023. SWOT captured surface signatures of high‐amplitude ISW, with SSHA exceeding 20 cm.

Terrestrial Runoff Divides the Central Arctic Ocean and Shapes the Biologically Relevant Marine Lightscape

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Arctic Ocean is undergoing drastic changes in its sea ice cover, but is also optically complex. Observations from summer 2022 across the western Eurasian Basin, show increased colored dissolved organic matter (CDOM) absorption from terrestrial‐derived runoff within the Transpolar Drift (TPD) in the Amundsen Basin, extending down to a depth

Refinement of Marine Gravity Anomaly Over Shallow Waters by Using Satellite-Derived Bathymetry

IEEE Transactions on Geoscience and Remote Sensing
Gravity anomaly over shallow waters is one of the fundamental data sources for studying sea level change, ocean currents, and water exchanges between coastal areas and open seas. However, the acquirement of gravity data over shallow waters faces multiple

The 2025 Mw 8.8 Kamchatka Megathrust: A Rapid Recurrence With Complex Heterogeneous Rupture

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract On 29 July 2025, a Mw 8.8 earthquake struck Kamchatka, ∼50 km from the 1952 Mw 9.0 megathrust hypocenter, exhibiting a comparable aftershock zone. We resolve the kinematic rupture process and slip distribution by combining teleseismic waveforms with high‐quality tsunami data.

U.S. Extended Continental Shelf Cruise to Map Gaps in Kela and Karin Ridges, Johnston Atoll, Equatorial Pacific Ocean [PDF]

, 2014
The objectives for cruise KM14-17 are to map the bathymetry of two gaps in two submarine ridges in the vicinity of Johnston Atoll. One ridge gap occurs along the informally named Keli Ridge (Hein et al., 2005) south of Johnston Atoll and the other ridge ...

Siderite Concretions in Svalbard Lake Sediments Capture 7,000 Years of Extreme Arctic Cold Season Climate Change

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Arctic warms faster than anywhere else on Earth, and paleoclimate data are key to placing this amplified response in a long‐term context. But most past temperature proxies record growing season conditions, when their biological signal carriers are produced.

Exploring the Most Effective Information for Satellite-Derived Bathymetry Models in Different Water Qualities

Remote Sensing
Satellite-derived bathymetry (SDB) is an effective means of obtaining global shallow water depths. However, the effect of inherent optical properties (IOPs) on the accuracy of SDB under different water quality conditions has not been clearly clarified ...
