Remote sensing of intertidal morphological change in Morecambe Bay, U.K., between 1991 and 2007 [PDF]

, 2010
Tidal Flats are important examples of extensive areas of natural environment that remain relatively unaffected by man. Monitoring of tidal flats is required for a variety of purposes. Remote sensing has become an established technique for the measurement

A novel approach for in situ benthic habitat characterization

Limnology and Oceanography: Methods, EarlyView.
Abstract Habitat heterogeneity is a key driver of temporal and spatial variability of subtidal marine benthic biodiversity. However, this makes it a challenging environment in which to measure and quantify the factors driving biodiversity in a consistent manner.

Nearshore Bathymetry Estimation Using Synthetic Aperture Radar (SAR) Imagery

Canadian Journal of Remote Sensing, 2021
A method to estimate nearshore bathymetry using SAR imagery is presented in this paper. A Fast-Fourier Transform (FFT) and Wavelet hybrid method is proposed to analyze the wave spectra and calculate the wavelength of the long swell waves from SAR ...

Assimilation of machine‐learning‐predicted nitrate to improve the quality of phytoplankton forecasting in the shelf‐sea environment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article demonstrates that assimilating machine‐learning‐derived surface nitrate can improve five‐day phytoplankton forecast substantially within the Met Office operational system for the Northwest European Shelf. We explain the reasons behind this improvement and propose that an online system where machine learning and data assimilation are cycled

Estimating Seafloor Topography of the South China Sea Using SWOT Wide-Swath Altimetry Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The surface water and ocean topography (SWOT) wide-swath altimetry satellite was launched in December 2022. The performance of novel wide-swath altimetry in seafloor topography modeling needs to be evaluated. This study utilized 15 cycles of SWOT Level-3

Interferometric synthetic aperture sonar large scale simulated data benchmark of a ship wreck

Electronics Letters, 2023
Interferometric synthetic aperture sonar (InSAS) systems produce high resolution seafloor imagery and 3‐D bathymetry by exploiting the phase differences between image pairs formed from data collected by vertically separated arrays.

Uncertainty Modeling for AUV Acquired Bathymetry [PDF]

, 2015
Autonomous Underwater Vehicles (AUVs) are used across a wide range of mission scenarios and from an increasingly diverse set of operators. Use of AUVs for shallow water (less than 200 meters) mapping applications is of increasing interest.

A review of the FATIMA Yellow Sea field campaign research

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The FATIMA marine fog project took place over the Sable Island region of eastern Canada (summer 2022) and the Yellow Sea of the Republic of Korea (ROK, summer 2023). Its goals are to improve marine fog monitoring and forecasting. Instrumented multiple research vessels, aircraft, tethered balloon and autonomous systems, ocean observation sites, and ...
