  • Improving the response to operational pollution in the South Iberian coast A Super-Ensemble backtracking approach
    Publication . Janeiro, João; Sepp Neves, Antonio Augusto; Martins, Flávio; Campuzano, Francisco
    Although for the general public marine oil pollution happens when an oil tanker sinks in the ocean or an accident occurs in an oil platform, most of the oil entering the world ocean does it along less obvious paths. This research work focus on operational spills. It provides a first indication of the uncertainty associated to backtracking simulations using solutions from several operational models available on the internet for the South Iberia region. The suitability of using a Super-Ensemble approach as a way of minimizing the uncertainty was also investigated. The methodology was validated using drifting buoys available for the region. Results show the advantages of using the Super-Ensemble while pointing out for the importance of the atmospheric forcing in this region due to its characteristic mesoscale activity. The absence of more trajectories sparse in time and geographic coverage was a limitation found.

    O litoral algarvio estende-se desde a foz da Ribeira de Odeceixe na Costa Oeste (37° 26’ 38,35’’ N; 008° 48’ 50,00’’ O) à foz do Rio Guadiana na costa Sul (37° 10’ 02,10’’ N; 007° 24’ 07’’ O) num total de cerca de 210 km. Este extenso litoral é constituído por morfologias costeiras muito diversas e talhado em formações com idades e litologias muito variadas. De um modo geral, a costa do Algarve pode ser dividida em i) litoral de arribas rochosas, ii) litoral de arribas arenosas e iii) litoral baixo, que se diferenciam entre si pelo substrato físico que os suporta e pelos processos dinâmicos responsáveis pela sua evolução.
  • The role of Ria Formosa as a waste water receiver
    Publication . Veríssimo, Filipe; Martins, Flávio; Janeiro, João
    Ria Formosa is a system of barrier islands that communicates with the sea through six inlets, situated in the Algarve, the most southern region of Portugal which encompasses the municipalities of Loulé, Faro, Olhão, Tavira and Vila Real de Santo António, covering an area of about 18,400 hectares along a 60 km stretch from the Ancão beach to Manta Rota beach (Figure 4.1). It is an area protected by the status of Natural Park, granted by Law n. º 373/87 of December 9th and its classified as a sensible area according to the law n.º 152/97 of June 19th concerning urban waste water discharges, in order to assure water quality standards for shellfish aquaculture. This ecosystem is very important from the socio-economic point of view, being responsible for 41% of the Portuguese national production of bivalve shellfish, with a small finfish production (IMAR, 2012).
