Shipping activity can be a substantial source of pollution and impact on the environment, including air, water ecosystems, as well adverse health climatic effects. Due to distribution maritime transport routes in EU, large portion population is exposed shipping throughout Europe. The ongoing European project EMERGE aims investigate quantify these impacts over Europe, more detail, specific case studies regions. Aveiro lagoon region Portugal one studies. This Natura 2000 area, also includes...
Abstract Drought can be considered an atmospheric condition, which rapidly goes beyond to affect multiple fields of the environment and human activities. The persistence these conditions recharge surface groundwater bodies due a decrease in volume runoff seepage, thus affecting environmental In this context, main aim work is characterize occurrence variability future droughts Galicia over twenty-first century. methodology followed based on calculation analysis Standardized Precipitation...
Estuarine systems currently face increasing pressure due to population growth, rapid economic development, and the effect of climate change, which threatens deterioration their water quality. This study uses an open-source model high transferability (Delft3D), investigate physics quality dynamics, spatial variability, interrelation two estuarine Portuguese west coast: Mondego Estuary Óbidos Lagoon. In this context, Delft3D was successfully implemented validated for both through...
Aquaculture is one of the fastest growing sectors in world. However, this may come with a cost, as increasing aquatic production likely to impose changes environment. To ensure ecosystem sustainability, it essential think on larger scale. This study aims use Delft3D model suite evaluate ecological carrying capacity for bivalve Sado Estuary (Portugal), under present and future conditions (2050). Scenarios increased oyster resulted reductions chlorophyll associated nutrient concentrations. In...
Shallow coastal lagoons driven by tidal processes are extremely dynamic environments prone to continuous natural and anthropogenic pressures. The hydrodynamics of these systems deeply depends on the effect local morphology propagation, so their permanent evolution constantly changes dependent processes. For this reason, present work aims review main characteristics Ria de Aveiro hydrodynamics, a shallow lagoon located at Atlantic Coast Portugal, evaluating its over last 30 years (between...
In the last decades, climate change has been accelerating, affecting, directly and indirectly, environment, animal habitats, daily human life. Earth System Models (ESMs) are valuable tools for studying these impacts, their performance over coastal regions is critical understanding how physical biogeochemical processes evolving through time they may in future. The continental Portuguese coast, characterized by an important upwelling system, hosts highly productive nutrient-rich with a large...
The main aim of this research was to assess the mercury transport from an estuarine basin with a background anthropogenic contamination during spring tidal cycle (year 2009) and compare it two previous cycles (years 1994 1999), as part long-term monitoring program. Results showed that effective occurs both in dissolved particulate fractions (0.18 0.20 kg per cycle, respectively), despite overall decrease environmental contamination, results more than double findings on system. These result...
Aquaculture is one of the food industries that most evolved in recent years response to increased human demand for seafood products, which has led a progressive stock threat nature. With high consumption per capita, Portugal been exploring its coastal systems improve cultivation fish and bivalve species with commercial value. In this context, study aims propose use numerical model as tool assess impact climate change on aquaculture site selection temperate estuarine system (Sado estuary)....

Storm surge impact in the hydrodynamics of a tidal lagoon: case Ria de Aveiro.Storm surges are hazardous phenomenon, since they may flood large coastal areas, causing socio-economical habitation losses. Thus, study their characteristics effects regions is crucial to prevent negative consequences. This work aims at assessing storm lagoon located north-western Portuguese coast (Ria Aveiro). amplitudes 0.58 m, 0.84 m 1.17 for 2,...
The northwestern coast of the Iberian Peninsula is a region characterized by pronounced hydrologic and biogeochemical activity, resulting in important fish shellfish resources whose exploitation has strong local socioeconomic impact. This high biological diversity strongly dependent on coastal upwelling induced favourable winds, which presents seasonal variability. motivates present study, aims to understand relation between circulation, hydrography Chl-a concentration under summer events...
The present study aims to research the physico-chemical processes in two under-researched coastal systems located on west and south Portuguese coast—Mira Estuary Ria de Alvor—through development exploitation of dedicated coupled physical water quality models. Both are highly dynamic, supporting a wide range biological diversity; however, they characterized by distinct environmental oceanographic conditions, enhancing importance comparative approach. In this context, Delft3D modeling suite...
In recent decades, several studies have highlighted the importance of temporal and spatial structure upwelling in defining high levels productivity coastal systems. This work intends to assess trends along west south Portuguese coasts from 1979 2020, comparing patterns between these regions. Two different methodologies calculate indexes (UI), based on wind sea surface temperature (SST) data, were applied relate wind-induced upwelling-favourable conditions (UIET) with expected response...
ABSTRACT The eastern boundaries of the world's oceans are among most productive marine regions owing to wind induced coastal upwelling. In this context, changes in upwelling influence chlorophyll‐a (Chl‐a) concentration along Northwest ( NW ) Iberian Peninsula (IP) coast. This work aimed evaluate and quantify meteorological conditions defined by circulation weather types CWTs on Chl‐a variability Galician A seasonal (April–September October–March) characterization satellite wind‐derived...
The interaction between tide, river runoff, and wind in coastal lagoons induces complex salinity gradients, which are remarkable when the meteorological forcing is exacerbated. This work aims to characterize structure under extreme freshwater events Ria de Aveiro lagoon (Portugal). Delft3D model was implemented validated 3D mode used perform simulations forced with scenarios. Results show that conditions determine stratification intensity location. Generally, increases as increases, while...
Coastal municipalities and industries often discharge poorly treated wastewater into proximate marine estuarine environments. The urban and/or effluent input can lead to eutrophication lower water quality, as it holds high concentrations of nutrients pollutants. One widely applied tool increase dispersion direct away from coastal areas, thus causing fewer impacts on human activities, is sea outfall. In Aveiro, Portugal, the São Jacinto outfall construction was completed in 1998; however,...
Abstract This study aims to investigate the potential changes in co-occurrence of strong precipitation and wind events over Iberian Peninsula using simulations from Coupled Model Intercomparison Project (CMIP) Phase 6 under two scenarios (SSP2 − 4.5 SSP5 8.5). Projected indicate a significant regional variability during all seasons. In winter, western regions are projected experience an increase compound as century progresses both scenarios, with significantly larger area being affected by...
Coastal lagoons hold significant ecological value due to their rich biodiversity and essential roles in supporting ecosystems.
