Abstract Monitoring small rivers during extreme events is challenging, especially in remote areas. This study assesses the accuracy of the Surface Water and Ocean Topography (SWOT) mission in characterizing an extreme hydrological event on a narrow river (∼60 m wide), using a landslide‐induced flood on the Chilcotin River (Canada) as a case study. SWOT

GRAVSAT error analysis by means of global spectral analyses of the marine geoid from SEASAT altimeter data [PDF]
The geographical variability of short wavelength geoid power spectra (geoid roughness), was mapped for the world's oceans between latitudes 72 deg N and 72 deg S. A spectral analysis of SEASAT altimeter data, reduced to sea surface heights, was performed

Abstract Landslides often generate long‐period seismic waves that propagate over large distances. During volcanic island collapses and their intrusion into seawater, seismic signals of >1 min periods are widely observed. The physical sources of these signals remain poorly understood due to complex landslide‐water interactions. In this paper, we perform

Satellite-derived bathymetry using Sentinel-2 in mesotidal coasts
Coastal zones are strategic environments of high socioeconomic, political, and ecological value, with over half of the world's population residing within 200 km of the coast. This proximity highlights their vulnerability to extreme events, which are exacerbated by global changes, leading to significant coastal impacts such as erosion, flooding, and ...

Estimating Ice Cover on the Great Lakes Using Seismic Ambient Noise
Abstract Lake ice impacts seismic noise on nearby seismometers, and therefore seismic observations can be used to monitor ice changes. However, the transfer function describing how lake‐microseism noise covaries with ice cover has not been quantified.

Science opportunities from the Topex/Poseidon mission [PDF]
The U.S. National Aeronautics and Space Administration (NASA) and the French Centre National d'Etudes Spatiales (CNES) propose to conduct a Topex/Poseidon Mission for studying the global ocean circulation from space.

Hydrodynamic models in coastal and estuarine systems are typically constrained by sparse bathymetry, boundary, and validation data, especially in regions where field campaigns are costly or impractical.

Spatial cross-correlation of Antarctic Sea ice and seabed topography [PDF]
A time series of derived sea ice concentrations as observed about Antarctica by the Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) satellite in 1983 is considered.
