An X-Band Radar System for Bathymetry and Wave Field Analysis in a Harbour Area

open access: yesSensors, 2015
Marine X-band radar based systems are well tested to provide information about sea state and bathymetry. It is also well known that complex geometries and non-uniform bathymetries provide a much bigger challenge than offshore scenarios.

Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).

A Novel Method for Estimating Wave Energy Converter Performance in Variable Bathymetry Regions and Applications

open access: yesEnergies, 2018
A numerical model is presented for the estimation of Wave Energy Converter (WEC) performance in variable bathymetry regions, taking into account the interaction of the floating units with the bottom topography.

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

High‐Resolution Satellite Imagery Reveals Landscape‐Scale Benthic Habitat Changes in a Turbid Coral Reef

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
High‐resolution satellite imagery and landscape metrics revealed a 77% decline in coral‐dominated habitats at Abrolhos Bank between 2010 and 2024, accompanied by macroalgal and zoanthid expansion. Spatial reorganisation indicates increasing fragmentation, homogenisation and loss of reef structural complexity.

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

MINS: Tightly coupled MultiBeam EchoSounder Inertial Navigation System for 3D bathymetric underwater inspection

open access: yesJournal of Ocean Engineering and Science
By fusing a MultiBeam EchoSounder (MBES) with an Inertial Measurement Unit (IMU) and a Doppler Velocity Log (DVL) we present MINS: a graph-based, tightly coupled, and featureless MBES-Inertial Navigation System that enables accurate and real-time robot ...

Bathymetry retrieval from optical images with spatially distributed support vector machines

open access: yesGIScience & Remote Sensing, 2019
This paper presents a spatially distributed support vector machine (SVM) system for estimating shallow water bathymetry from optical satellite images. Unlike the traditional global models that make predictions from a unified global model for the entire ...

Artificial Intelligence for Blue Transformation: A Review of Predictive Modeling and Decision Support Systems in Sustainable Aquaculture

open access: yesSustainable Development, EarlyView.
ABSTRACT The FAO's “blue transformation” roadmap necessitates a fundamental shift towards precision aquaculture to meet global food security targets while minimizing environmental footprints. This review provides a comprehensive overview of how artificial intelligence (AI) and decision support systems (DSS) serve as pivotal enablers for the “better ...
