Western Mediterranean shelf-incised submarine canyons: multi-proxy evidence of ...
López-Quirós, Adrián; Puga-Bernabéu, Ángel; José Lobo, Francisco; Ruíz-Caballero, Elvira; Cerrillo-Escoriza, Javier; Pérez-Asensio, José N.Submarine canyons play a critical role in continental margin sediment transport, functioning both as sediment traps and conduits. This study examines the depositional dynamics of the Motril, Carchuna, and Calahonda canyons in the northern Alboran Sea (western Mediterranean) to assess their role in Holocene sediment storage and transfer. Comprehensive sedimentological and elemental geochemical analyses reveal di...
Novel field experiment on alkalinity enhancement in intertidal environments—a t...
Mendes, Isabel Maria de Paiva Pinto; Lübbers, J.; Schönfeld, J.; Baldermann, A.; Carrasco, Rita; Cravo, Alexandra; Gomes, Ana; Grasse, P.One recently proposed approach to reduce atmospheric CO2 concentrations is marine alkalinity enhancement. This technique increases the CO2 uptake capacity of seawater through weathering of fine-grained (mafic) rocks and minerals in marine environments. The weathering process has been extensively tested in laboratory studies and verified by numerical models. Field experiments scaling the CO2 uptake under natural...
The late holocene evolution of the adra delta subaqueous system (Northern Albor...
Bárcenas, P.; Lobo, F.J.; Fernández-Salas, L.M.; Mendes, Isabel Maria de Paiva Pinto; López-González, N.; Macías, J.The formation and development of a small Mediterranean deltaic system are investigated through a primary seismic stratigraphic interpretation of a high-resolution seismic profile network, combined with multiple bathymetric data (including multibeam bathymetric imagery) and collated with shallow sediment cores collected with a vibro-corer device. The submarine delta of the Adra River is divided into a basal patc...
Variable downcanyon morphology controlling the recent activity of shelf-incised...
Cerrillo-Escoriza, J.; Lobo, F. J.; Puga-Bernabéu, Á.; Bárcenas, P.; Mendes, Isabel Maria de Paiva Pinto; Pérez-Asensio, J. N.; Durán, R.This research aims to distinguish genetic sedimentary processes building canyon geomorphological patterns and the factors driving different sedimentary activities in two nearby Mediterranean shelf-incised submarine canyons (Carchuna and Motril) that exhibit different degrees of incision on the narrow margin of the northern Alboran Sea. The straight Carchuna Canyon incises the shelf up to 200 m off the coastline...
Benthic foraminifera as palaeo-environmental indicators in the Northern Gulf of...
Mendes, Isabel Maria de Paiva PintoThis thesis is an investigation of benthic foraminifera as palaeo-environmental indicators on the Northern Gulf of Cadiz continental shelf, northeast Atlantic Ocean. The main objective was to determine the environmental indicator value of living benthic foraminifera and their application to Holocene palaeoenvironmental reconstruction. Relationships between living benthic foraminiferal fauna and both physical an...
