Sea Trials of the SWATH Ship USNS Victorious (T-AGOS 19)
Marine Technology and SNAME News, 1994In 1986 the design of the Navy's first large SWATH (small waterplane area twin hull) ship was completed. Designated the T-AGOS 19 Class, these vessels were designed to operate comfortably in high latitudes during winter months. The T-AGOS 19 and T-AGOS 23 Classes represent one of the greatest departures in naval surface ship design in the past century.

Measurements during SWATH ship sea trials
IEEE Instrumentation & Measurement Magazine, 2000A new ship must undergo a rigorous set of sea trials to receive final certification. The sea trials program measures the vessel's performance against its design specifications and code requirements. The performance evaluation includes the ship's powering requirements (ability to achieve and maintain its design speed in a variety of conditions), fuel ...

The Nile deep sea fan: preliminary results from a swath bathymetry survey
Marine and Petroleum Geology, 2001We present and discuss a set of data, mainly swath bathymetry, backscatter images and a few seismic data, that have been recently recorded over large areas of the Nile deep-sea fan between water depths of 1200 and 3000 m. These data demonstrate the presence of at least three distinct morphostructural provinces where interacting sedimentary, tectonic ...

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 ...

Swath bathymetric investigation of the seamounts located in the Laxmi Basin, Eastern Arabian Sea
Marine Geodesy, 1994Multibeam (Hydrosweep) swath bathymetric investigations revealed the presence of a NNW trending linear seamount chain along the axial part of the Laxmi Basin in the eastern Arabian Sea, between 15°N, 70°15'E and 17°20'N, 69°E. This chain consists of three major edifices: RAMAN1 and PANIKKAR2 seamounts and WADIA2 guyot.

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

Simulation of the Wide Swath Sea Surface Height Calibration Using GNSS Buoy Array
IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020The calibration and validation task is very challenging for new-generation wide swath altimeters. There are two error terms sensitive to the across-track distance to the satellite nadir: the roll error which is proportional to the across-track distance, and the baseline length bias which is proportional to the square of the across-track distance.

Ahstract-A comprehensive description of the Sea State Bias (SSB) for wide-swath interferometric (WSI) altimetry is proposed using a two-scale transfer function of the first-of-its-kind instrument, the KaRIn instrument of the SWOT mission. We show that the SSB encompass the contribution of the ElectroMagnetic Bias (EMB) similarly to conventionnal ...

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.

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 ...
