Remote Sensing in Ecology and Conservation, EarlyView.Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...

Tropical Cyclone Rainfall Spatial Asymmetries in the Lesser Antilles
International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.Rainfall is not proportional to the Saffir‐Simpson wind‐based categories. Lower category tropical cyclones (TS, H1, H2 and H3) can generate more intense rainfall than H4 and H5. Rainfall is asymmetric; as a tropical cyclone intensifies or weakens, the location of peak rainfall shifts.

Oil Spills and Slicks Imaged by Synthetic Aperture Radar [PDF]
, 2013 Oil spills and slicks occur in the ocean around the world due to natural seeps, oil extraction, transportation, and consumption. Satellite synthetic aperture radar (SAR) has proven to be an efficient tool for identifying and classifying oil on the sea ...

Interseismic Creep Along the Enriquillo–Plantain Garden Fault, Haiti, Estimated From InSAR
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The Enriquillo–Plantain Garden fault zone (EPGFZ) is a major left‐lateral strike‐slip fault in southern Haiti hosting several recent destructive earthquakes, including the 2021 MW 7.1 Nippes event with primary thrust‐slip. To investigate how strain is accommodated in the vicinity of the 2021 event, we analyzed Sentinel‐1 interferometric ...

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Swell propagation and transformation across variable bathymetry and coastal obstacles fundamentally control nearshore wave energy redistribution, sediment transport, and shoreline evolution. Conventional satellite altimetry cannot adequately resolve these dynamics, particularly refraction and diffraction as swell transition into shallow waters.

Nonlinear Internal Waves in Synthetic Aperture Radar Imagery
, 2013 Synthetic aperture radar (SAR) has contributed significantly to the study and understanding of oceanic nonlinear internal waves. Although they travel within the ocean's interior, currents associated with internal waves produce variations in ocean surface

Reconstructing Marine Boundary Layer Jets Over the South China Sea Using Machine Learning
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Marine boundary layer jets (MBLJs) over the South China Sea (SCS) play a critical role in coastal heavy rainfall, yet their structure remains uncertain due to limited wind observations over the ocean. Here, we develop a U‐Net–based reconstruction framework to estimate 950‐hPa winds from satellite‐derived sea surface winds, providing a ...

From Lotic to Lentic: SWOT Characterizes Seasonal Hydrodynamics in the Lake‐River Continuum
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract The interface between rivers and lakes forms a unique hydraulic continuum, in which lotic and lentic regimes dynamically interact and transition between each other. A common expression of this lake‐river continuum (LARIC) is reservoir backwater, where water surface gradually rises from the reservoir pool upstream to the free‐flowing river ...

Seasonal Characteristics of Mesoscale Convective Systems Over the Philippines
International Journal of Climatology, Volume 46, Issue 7, 15 June 2026.This study examines how mesoscale convective systems (MCSs) over the Philippines are most frequent during boreal summer, while those in winter are longer‐lived and more intense due to cold surges and enhanced easterly moisture transport. Intraseasonal oscillations, such as the Madden‐Julian Oscillation (MJO) and the Boreal Summer Intraseasonal ...
