Mapping the distribution and evaluating the impacts of marine non-indigenous species (NIS) are two fundamental tasks for management purposes, yet they are often time consuming and expensive. This case study focuses on the NIS gilthead seabream Sparus aurata escaped from offshore farms in Madeira Island in order to test an innovative, cost-efficient...
Monitoring marine contamination by floating litter can be particularly challenging since debris are continuously moving over a large spatial extent pushed by currents, waves, and winds. Floating litter contamination have mostly relied on opportunistic surveys from vessels, modeling and, more recently, remote sensing with spectral analysis. This stu...
Introduction
Anthropogenic litter on the sea surface, beaches and seafloor has been significantly increasing over recent decades (Galgani et al. 2015). In present days, marine litter is worldwide distributed, and the Atlantic Island of Madeira is no exception (Álvarez et al. 2020). This accumulation of litter in the ocean is severely affecting oce...
Macroalgal forests play a key role in shallow temperate rocky reefs worldwide, supporting communities with high productivity and providing several ecosystem services. Sea urchin grazing has been increasingly influencing spatial and temporal variation in algae distributions and it has become the main cause for the loss of these habitats in many coas...
"Researchers are still finding new forms of plastic pollution and contamination worldwide (Gestoso et al., 2019; Haram et al., 2020), but one thing is clear: tackling plastic pollution in the marine environment requires concerted strategies and strong actions from policy makers and stakeholders on a global scale. Indeed, several efforts are already...
A major concern of coastal engineering is not only to access the damage to coastal structures by severe wave overtopping, but also the hazard imposed to users. Local hazard is often associated to the volume of overtopping water per unit of time (called overtopping discharge). Despite two decades of intensive research, it is yet not fully clear to p...

Accurate prediction of the occurrence and morphological consequences of overwash are important for coastal flood risk assessment and management. A number of morphological and oceanographic factors controlling overwash have been identified by several authors, including nearshore bathymetry. This work intends to identify alongshore variations in stor...
Overwash prediction is very important for coastal zone management. This work intends to identify alongshore variations in storm impact and evaluate the role of sub-aerial and submerged morphologies in overwash occurrence. For this study, 24 cross-shore topo-bathymetric profiles were set on Barreta Island (Ria Formosa barrier island system, Portugal...
Projects
Project (1)
CleanAtlantic aims to protect biodiversity and ecosystem services in the Atlantic Area by improving capabilities to monitor, prevent and remove (macro) marine litter. The project will also contribute to raise awareness and change attitudes among stakeholders and to improve marine litter managing systems.
The main objectives of the project are:
To draw a picture of current situation, existing knowledge, data and initiatives in the Atlantic regions and definition of gaps.
Review of current systems to monitor and record marine litter, and to deliver protocols, tools and indicators to fill monitoring needs.
Development of modelling tools to predict the origin, circulation, and fate of marine litter, and elaboration of regional maps of hotspots of accumulation using models, remote sensing technologies, and aerial, surface and underwater unmanned systems.
To address prevention by developing best practices to reduce inputs from fishing and port sectors.
To tackle removal of marine litter by implementing initiatives of fishing for litter, to reduce the presence of “abandoned lost and otherwise discarded fishing gears” on the sea-bed, and to develop best practices for routine beach litter clean-up by local authorities.
To deliver training and awareness activities addressed to various audiences and to transfer project outputs to competent authorities and key stakeholders to improve management and facilitate MSFD (Marine Strategy Framework Directive) implementation.
