Coastal warming under climate change: global, faster and heterogeneous
Varela, R.; de Castro, M.; Dias, J. M.; Gómez-Gesteira, M.The assessment of expected changes in coastal sea surface temperature (SST) on a global scale is becoming increasingly important due to the growing pressure on coastal ecosystems caused by climate change. To achieve this objective, 17 Global Climate Models from CMIP6 were used, with data from historical and hist-1950 experiments spanning 1982-2050. This analysis highlights significant warming of coastal areas w...
Suitability of wave energy converters in northwestern Spain under the near futu...
Arguilé-Pérez, B.; Ribeiro, A.S.; Costoya, X.; deCastro, M.; Gómez-Gesteira, M.Marine renewable energies can play a key role by reducing the dependency on fossil fuels and, therefore, mitigating climate change. Among them, it is expected that wave energy will experience rapid growth in the upcoming decades. Thus, it is important to know how wave climate will change and how suitable the wave energy converters (WECs) will be to the new wave conditions. This paper aims to evaluate the capabi...
How can ocean warming at the NW Iberian Peninsula affect mussel aquaculture?
Des, M.; Gómez-Gesteira, M.; deCastro, M.; Gómez-Gesteira, L.; Sousa, M. C.Understanding and forecasting future consequences of climate change in mussel aquaculture industry require the assessment of changes in physical parameters which may affect mussel growth. The FLOW module of Delft3D model forced with climatic data was validated and calibrated for the Rías Baixas (NW Iberian Peninsula), one of the areas with the highest mussel production in the world. This model was used to perfo...
The impact of climate change on the geographical distribution of habitat-formin...
Des, M.; Martínez, B.; deCastro, M.; Viejo, R. M.; Sousa, M. C.; Gómez-Gesteira, M.In the current scenario of climate change characterized by a generalized warming, many species are facing local extinctions in areas with conditions near their thermal tolerance threshold. At present, the southern limit of the geographical distribution of several habitat-forming algae of cold-temperate affinities is located in the Northwest Iberian Peninsula, and the Rías Baixas may be acting as contemporary re...
Projections of wind energy resources in the Caribbean for the 21st century
Costoya, X.; deCastro, M.; Santos, F.; Sousa, M.C.; Gómez-Gesteira, M.The Caribbean has suitable conditions for a significant wind energy development, which makes a good planning for the future renewable energy mix essential. The impact of climate change on Caribbean wind power has been analyzed by means of an ensemble of CORDEX regional climate models (RCMs) under the RCP8.5 warming scenario. The offshore wind energy resource was classified for the historical period and for the ...
Differences in coastal and oceanic SST trends north of Yucatan Peninsula
Varela, R.; Costoya, X.; Enriquez, C.; Santos, F.; Gómez-Gesteira, M.The coastal area north of Yucatan has experienced a cooling SST trend from 1982 to 2015 during the upwelling season (May–September) that contrasts with the warming observed at the adjacent ocean area. Different drivers were analyzed to identify the possible causes of that unusual coastal cooling. Changes in coastal upwelling and in sea-atmosphere heat fluxes are not consistent with the observed coastal cooling....
Changes in sea surface temperature seasonality in the Bay of Biscay over the la...
Costoya, X.; deCastro, M.; Gómez-Gesteira, M.; Santos, F.Sea surface temperature (SST) variability was analyzed for the Bay of Biscay over the period 1982–2014 using data from NOAA 1/4 degree daily OI database. Trends were analyzed on a monthly scale since previous studies suggest that the rate of change was not homogeneous at annual and seasonal scales. The warming calculated for the whole area at the annual scale was 0.26 ± 0.03°C dec−1, although the intensity was ...
Has upwelling strengthened along worldwide coasts over 1982-2010?
Varela, R.; Álvarez, I.; Santos, F.; deCastro, M.; Gómez-Gesteira, M.Changes in coastal upwelling strength have been widely studied since 1990 when Bakun proposed that global warming can induce the intensification of upwelling in coastal areas. Whether present wind trends support this hypothesis remains controversial, as results of previous studies seem to depend on the study area, the length of the time series, the season, and even the database used. In this study, temporal and...
Analysis of the influence of river discharge and wind on the Ebro turbid plume ...
Fernández-Nóvoa, D.; Mendes, R.; deCastro, M.; Dias, J. M.; Sánchez-Arcilla, A.; Gómez-Gesteira, M.The turbid plume formed at many river mouths influences the adjacent coastal area because it transports sediments, nutrients, and pollutants. The effects of the main forcings affecting the Ebro turbid plume were analyzed using data obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard the Aqua and Terra satellites over the period 2003–2011. Composite images were obtained for day...
Sensitivity of the WRF model wind simulation and wind energy production estimat...
Carvalho, D.; Rocha, A.; Gómez-Gesteira, M.; Silva Santos, C.This work aims to assess the Weather and Research Forecasting (WRF) model wind simulation and wind energy production estimates sensitivity to different planetary boundary layer parameterization schemes. Five WRF simulations considering different sets of planetary boundary layer (PBL) and surface layer (SL) parameterization schemes were performed, and their results compared to measured wind data collected at fiv...
