Abstract. With knowledge of typical hydrodynamic behavior waste plastic material, models predicting the dispersal benthic plastics from land sources within ocean are possible. Here we investigated (density, settling velocity and resuspension characteristics) non-buoyant preproduction pellets in laboratory. From these results used MOHID modelling system to predict what would be likely transport deposition pathways such material Nazaré Canyon (Portugal) during spring/summer months 2009...
Abstract. This paper presents the structure and application of a regional scale operational modelling tool for West Iberian coast, discusses its potential products services both scientific coastal management activities. The forecasting suite includes nested hydrodynamic models forced with up-to-date meteorological forecast data large-scale model results. present status system recent upgrades are reviewed, offering general description main components system: forcing data, circulation model,...
Obtaining a comprehensive knowledge of the spatial and temporal variations environmental factors characterising Azores region is essential for conservation management purposes. Although many studies are available region, there need general overview best information. Here, we assembled collection data briefly described ocean climatology its variability in Azores. Data sources used this study included remote sensing oceanographic 2003-2013 (sea surface temperature, chlorophyll-a concentration,...
Coastal ocean observing and modeling systems (coastal observatories), connected with regional global systems, improve the quality of information forecasts for effective management safe sustainable maritime activities. The public availability systematic long-term is an engine Blue Economy, boosting economic growth, employment, innovation. An overview some Brazilian initiatives presented in this paper, involving universities, private companies, federal state agencies, covering institutions...
Light pollution critically affects fledglings of burrow-nesting seabirds, leading to massive mortality events. The successful management this pollutant depends upon a comprehensive understanding the factors influencing visual sensitivity and corresponding behaviours towards light. Factors shaping development system could account for variation in seabirds' vulnerability light pollution. We investigated how Cory's shearwater chicks respond selected contrasting artificial stimuli. Chicks were...
Seabirds, and particularly fledglings of burrow-nesting species, are greatly impacted by light pollution. During their inaugural flights from colony to sea, become grounded after encountering artificial light. Such groundings, or fallout events, affect many each year causing mass mortality events. To mitigate this induced mortality, rescue programs have been implemented for decades at locations worldwide. Despite the notoriety fallouts conservation implications, contributing behavioural...
The hydrodynamics of the TagusROFI (Regions Freshwater Influence) is affected by coastal upwelling, estuarine tidal flow, thermohaline circulation that modulated Tagus freshwater discharge, and its complex bathymetry. use numerical models best way to explain processes characterize this region. These are also crucial answer important scientific management questions. Nevertheless, robustness products derived from depend on their accuracy therefore must be validated determine uncertainty...
It is increasingly recognised that deep-sea mining of seafloor massive sulphides (SMS) could become an important source mineral resources. These operations will remove the targeted substrate and produce potentially toxic plumes from in situ seabed excavation return water pumped back down to seafloor. However, spatial extent impact still uncertain because few field experiments models plume dispersion have been conducted. In this study, we used three-dimensional hydrodynamic Azores region...
Abstract A large-scale climatic ocean circulation model was used to study the Atlantic Ocean circulation. This inverse is an extension of β-spiral formulation presented in papers by Stommel and Schott with a more complete version vorticity equation, including relative addition planetary vorticity. Also, database for hydrological measurements used, not only National Oceanographic Data Center but also World Circulation Experiment data cruises near Azores, Angola, Guinea-Bissau. detailed...
Abstract The applicability of a numerical model following downscaling methodology was evaluated for the south-eastern Brazilian shelf (regional model) and Paranaguá estuarine system (local model). This approach permits simulation different scale processes, such as storm surges coastal upwelling, is suitable operational forecasting purposes. When large areas are covered by regional models, tidal propagation inside domain can be significantly affected local potential, mainly where resonance...
ABSTRACT Seabirds, and particularly fledglings of burrow-nesting species, are greatly impacted by light pollution. During their inaugural flights from colony to sea, become grounded after encountering artificial light. Such groundings, or fallout events, affect many each year. To mitigate this induced mortality, rescue programs have been implemented for decades in locations worldwide. Despite the notoriety fallouts, contributing behavioural biological factors remain mostly unknown. How do...
Abstract. In this study, a hydrodynamic model was applied to the Nazaré submarine canyon with boundary forcing provided by an operational forecast for west Iberian coast spring of 2009. After validation, lagrangian transport coupled study and compare patterns three different classes organo-mineral aggregates along canyon. The results show that in is neither constant, nor unidirectional there are preferential areas where deposited matter resuspended redistributed. larger class size (2000 μm...
This work presents a model for ocean drift simulations data obtained with the MOHID software in Campos Basin (RJ, Brazil) to study oil environmental issues. Results were compared satellite data, as well temperature and salinity by ARGO drifters available region.
Extensive rhodoliths and deep-water coral has been described along the continental shelf slope of Campos Basin, but such environments can be highly vulnerable to bottom trawling fishing. This study applied MOHID software simulate sediment resuspension during operation evaluate possible impacts deposition onto coral. The transport model was validated by field measurements a presented good accuracy. results indicated that double-rig induced 0.13 mm layer from which potential deleterious...
In this work it is simulated the trajectory of a beached whale sighted near Ilhabela region, in São Paulo coastline, Brazil, November, 2017.The computational implementation was performed on MOHID platform (HIDrodynamicsMOdel), using Water module.The downscaling technique used to obtain local hydrodynamic currents at scale.The validity model considered satisfactory after comparing results satellite measurements sea surface temperature and also salinity profiles measured by ARGO buoys,...
The study of larval dispersal and connectivity between deep-sea populations is essential for the effective conservation management environments design implementation Marine Protected Areas. Dense sponge aggregations, known as “sponge grounds”, are a key component marine benthic ecosystems, by increasing structural complexity sea floor providing structure habitat many other species. These aggregations characteristic Azores environment. sessile organisms rely primarily on their reproduction....
