A review of the FATIMA Yellow Sea field campaign research

open access: yesQuarterly 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 ...

Reconstruction and inversion of lake water depth based on ICESat-2 photon and Sentinel-2 — A case study of Caiduochaka Lake on the Tibetan Plateau

open access: yesJournal of Hydrology: Regional Studies
Study region: Caiduochaka Lake (CK) on the Tibetan Plateau (TP). Study focus: This study reconstructs the bathymetry of CK by integrating Sentinel-2's large-area, spatially continuous spectral data with precise but spatially discontinuous depth ...

Uncertainty Modeling for AUV Acquired Bathymetry [PDF]

open access: yes, 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.

Dynamical ocean forcing of the Madden-Julian Oscillation at lead times of up to five months [PDF]

open access: yes, 2011
We show that a simple three-dimensional ocean model linearised about a resting basic state can accurately simulate the dynamical ocean response to wind forcing by the Madden-Julian Oscillation (MJO).

Near‐resonant excitation of the Adriatic barotropic modes: The seiche events of December 2019

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study examines severe flooding in the northern Adriatic Sea in December 2019, which existing forecasting systems failed to predict. Analysis of wind and sea‐level data, alongside reanalysis datasets and a high‐resolution hydrodynamic model, revealed a wind‐induced resonance mechanism.

Design and Implementation of a Dual Uncrewed Surface Vessel Platform for Bathymetry Research Under High-Flow Conditions

open access: yesIEEE Access
Bathymetry, the study of underwater depth and topography, relies on detailed sonar mapping of the underwater structures. These measurements, critical for infrastructure health monitoring and hazard detection, often require prohibitively expensive sensory

Reconnaissance Surveying using Satellite-derived Bathymetry [PDF]

open access: yes, 2015
False Pass, AK, USA, is the eastern-most passage through the Aleutian Islands between the Bering Sea and the Pacific Ocean and provides a passage for small to mid-size vessels. The passage is considered an alternative route to Unimak Pass, AK for vessels

Dimension reduction for Gaussian process emulation: an application to the influence of bathymetry on tsunami heights [PDF]

open access: yes, 2016
High accuracy complex computer models, or simulators, require large resources in time and memory to produce realistic results. Statistical emulators are computationally cheap approximations of such simulators.

Modulation of wind drag by tidal currents in an embayment

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Tidal currents modulate how wind energy enters the surface wave field by influencing both wave drag and wave generation. In Shark Bay, following currents reduce effective wave steepness and wind drag, and opposing currents enhance wave growth. Wind energy is partitioned between wave drag and the creation of new waves, explaining observed tidal ...

The planktonic food web in the Gulf of Naples based on the analysis of carbon and nitrogen stable isotope ratios

open access: yesMarine Ecology, EarlyView., 2023
Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...
