CAMPANHA DE RASTREIO ACÚSTICO “PELAGO23” SÉRIE PNAB/DCF – PELAGO (Primavera)
Anxo Conde; Angélico, Maria Manuel; Pablo Carrera,; Henriques, Elisabete; Elisabete Henriques,; Elisabete Henriques,; Mendes, Hugo; Oliveira, Paulo B.O objetivo da campanha PELAGO23 foi determinar a distribuição espacial da sardinha, biqueirão e cavala, e estimar a sua abundância e biomassa, assim como avaliar a estrutura da comunidade de peixes pelágicos, a distribuição e abundância de ovos e larvas, o censo de aves e mamíferos e a caracterização das condições ambientais na plataforma continental portuguesa e Baia de Cádis. A campanha decorreu de 15 de març...
New physical and biological evidence of lateral transport affecting dinoflagell...
García-Moreiras, Iria; Hatherly, Melissa; Zonneveld, Karin; Dubert, Jesus; Nolasco, Rita; Santos, Ana Isabel; Oliveira, Anabela; Moita, Teresantroduction The production of resting cysts is a key dispersal and survival strategy of many dinoflagellate species. However, little is known about the role of suspended cysts in the benthic nepheloid layer (BNL) in the initiation and decline of planktonic populations.Methods In September 2019, sampling of the dinoflagellate cyst community at different water depths in the water column and in the bottom sediment...
Phytoplankton communities in two wide-open bays in the Iberian upwelling system
Santos, Mariana; Moita, Maria Teresa; Oliveira, Paulo B.; Amorim, AnaThe main meteorological and oceanographic drivers shaping phytoplankton community structure and dynamics are investigated in two wide-open bays influenced by coastal upwelling. Local processes influencing the proliferation of harmful algal bloom species were also investigated. The work was developed during one year in Lisbon Bay (central-west coast) and in Lagos Bay (south coast), both located on the upwelling ...
Characterizing phytoplankton biomass seasonal cycles in two NE Atlantic coastal...
Santos, Mariana; Mouriño, Helena; Calixto De Jesus Moita Garnel, Maria Teresa; Silva, Alexandra; Amorim, Ana; Oliveira, Paulo B.The seasonal and interannual variability of chlorophyll a was studied between 2008 and 2016 in two coastal bays located in the northeastern limit of the Iberia/Canary upwelling ecosystem. The work aims (i) to understand if small latitudinal distances and/or coastline orientation can promote different chlorophyll a seasonal cycles; and (ii) to investigate if different meteorological and oceanographic variables c...
Environmental representativity in marine protected area networks over large and...
Stratoudakis, Yorgos; Hilário, Ana; Ribeiro, Cláudia; Abecasis, David; Gonçalves, Emanuel J.; Andrade, Francisco; Carreira, Gilberto P.Converting assemblages of marine protected areas (MPAs) into functional MPA networks requires political will, multidisciplinary information, coordinated action and time. We developed a new framework to assist planning environmental representativity in a network across the marine space of Portugal, responding to a political commitment to protect 14% of its area by 2020. An aggregate conservation value was estima...
Ocurrence of Ostreopsis in two temperate coastal bays (SW iberia): Insights fro...
Santos, Mariana; Oliveira, Paulo B.; Moita, Maria Teresa; David, Helena; Caeiro, Maria Filomena; Zingone, Adriana; Amorim, Ana; Silva, AlexandraThe benthic genus Ostreopsis contains toxic-bloom forming species and is an important cause of concern in warm-temperate and tropical waters. On the coast of Portugal, NE Atlantic, the occurrence of Ostreopsis cf. siamensis and Ostreopsis cf. ovata has been reported since 2008 and 2011, respectively. This work aims to understand the favorable conditions for high concentrations of Ostreopsis cells in the plankto...

Glass eel (Anguilla anguilla) recruitment to the river Lis: Ingress dynamics in...
Stratoudakis, Yorgos; Oliveira, Paulo B.; Teles-Machado, Ana; Oliveira, José Manuel; Correia, Maria João; Antunes, CarlosTo provide new information on the ingress dynamics of glass eels at the Portuguese coast, the study analyzes catch per unit effort (CPUE) data from river Lis, biometric data from recruits in basins of western Portugal and meteo‐oceanographic data from the Iberian margin and shelf. Biometric data of glass eels in western Portugal are congruent with the latitudinal size gradient of leptocephali in oceanic surveys...
Toward predicting Dinophysis blooms off NW Iberia: a decade of events
Moita, Maria Teresa; Pazos, Yolanda; Rocha, Carlos; Nolasco, Rita; Oliveira, Paulo B.Dinophysis acuminata and Dinophysis acuta are recurrent species off NW Iberia but their outbreaks occur under different conditions. A decade (2004-2013) of weekly data for each species at two sentinel stations located at the entrance of Rias de Aveiro-AV (NW Portugal, 40 degrees 38.6' N) and Pontevedra-PO (Galicia, Spain, 42 degrees 21.5' N), were used to investigate the regional synchronism and mesoscale diffe...
