Satellite-derived sea ice motion data: daily-maps (DM) and swath-to-swath (S2S)
Remotely sensed ice motion is a crucial component in sea, lake, or river ice research. Over the past few decades, the ice movement has been detected and retrieved predominantly through the application of the Maximum Cross-Correlation (MCC) technique by analyzing the overlapped consecutive satellite images.Traditionally, ice motion products have been ...Tian Tian +6 more

Towards remote sensed wide-swath sea states from scatterometer: machine learning approach for ASCAT
Remote Sensing of the Ocean, Sea Ice, Coastal Waters, and Large Water Regions 2020, 2020For decades, the global remotely sensed significant wave heights have been from altimeters and/or synthetic aperture radars in wave mode, which both suffer from spatial and temporal sampling limitations. In contrast, spaceborne scatterometers are with large swath and high temporal revisit frequency at a global scale, but so far are routinely providing ...

Copernicus Sentinel-1 Synthetic Aperture Radar (SAR) mission systematically acquires data in Interferometric Wide swath mode over European land and water. This study investigates the potential of this data processed into Level-1 (L1) Single Look Complex (SLC) to compute meaningful image cross-spectra over the ocean to retrieve ocean surface waves ...

GLORIA and SeaMARC II sea-floor images of offshore Western Samoa reveal large-scale mass movements, volcanism, and structural modification. These processes are driven by hot-spot mantle diapirism and nearby plate subduction. Debris avalanche deposits extend from the island slope onto the adjacent abyssal plains, covering at least 20,000 km2.

Abstract A method to approximately model the sea, for short and long crested waves is described in this paper. Depth effects are included since this study grew out of a previous study looking into the application of this technique in the shallow running of torpedoes, Chinn and Roberts (1993).

The continental slope offshore Nice is a natural laboratory to investigate submarine landslides and gravity-flow processes. Using EM300 bathymetry data (spatial resolution of 25 m), about 250 scars with volume less than 8 × 108 m3 were identified. The AUV bathymetric data (spatial resolution of 2 m) revealed a greater number of scar-related failures ...

Spaceborne radiometers have enabled global sea-ice distribution observations since 1979, yet design choices associated with conventional daily-averaged remote sensing products mean that they do not resolve higher-frequency variability that characterizes Antarctic sea ice.

Early Assessment of SWOT’s Swath-mapping Capabilities over Arctic Sea Ice
The routine measurement of sea ice, an essential climate variable, is urgently needed for improving seasonal sea ice forecasting and tracking ocean-ice-atmosphere interactions. Over the last few decades, ocean remote sensing techniques have revealed significant and rapid declines in both the extent and volume of Arctic sea ice, driven by accelerated ...Sinead L.
