To date, ISA has issued three contracts for exploration for polymetallic sulphide deposits in the Area of the Northern Mid-Atlantic Ridge, which are rich in metals such as copper, zinc, lead, gold and silver. Once developed, the aim of the REMP will be to ensure effective environmental protection of this area as required by article 145 of the UN Convention on the Law of the Sea (UNCLOS). 2019-11-01T00:00:00Z http://hdl.handle.net/10174/13490 Title: Underwater Mining Institute 2014 - Harvesting Seabed Mineral Resources in Harmony with Nature Authors: Barriga, Fernando; Relvas, Jorge; Madureira, Pedro; Madureira, Álvaro; Conceição, Patrícia; Lee, Célia Abstract: The 43rd Conference of the Underwater Mining Institute September 21–28, 2014 • Lisbon, Portugal Come and join us in sunny Portugal, where Heritage speaks of the great sea discoveries, celebrated in innumerable unique monuments, side by side with narrow, medieval streets like live Renoir paintings in every corner. Experience the famous Portuguese hospitality, and its remarkable cuisine and wines. Listen to Fado. It is a small country above sea level, but with a huge underwater realm. Visit modern research institutes and famous mines, some generated on, and under seafloors. Find yourself visiting a country where multi-cultures live in harmony — European, American (North and South), African and Asian, and yet with a unique Portuguese soul, waiting for you to discover. Come and join the next UMI. Portugal welcomes you. 2014-08-31T23:00:00Z http://hdl.handle.net/10174/8041 Title: Evolução paleozóica da Gondwana Authors: Dias, Rui; Schmitt, Renata Abstract: Durante o Paleozóico a actuação de diversos ciclos de Wilson levaram, não só à unificação da Gondwana mas também da própria Pangeia. Se alguns destes ciclos são exclusivamente paleozóicos (é o caso do orógeno Varisco nos sectores setentrionais), outros resultam de processos extensivos iniciados no final do Neoproterozóico e cujas fases colisionais só ocorreram no Paleozóico inferior (e.g. orogenia Búzios - SE do Brasil). Neste simpósio serão abordados os processos e mecanismos associados à evolução geodinâmica da Gondwana durante o Paleozóico. 2012-01-01T00:00:00Z http://hdl.handle.net/10174/8040 Title: Da deriva continental de Wegener (1912) à moderna geodinâmica global Authors: Dias, Rui Abstract: Alfred Wegener formalizou o conceito de deriva continental (1912-1915) com base na mobilidade da superfície sólida da Terra; ele teve precursores mas, como meteorologista, conhecendo os movimentos rápidos dos fluidos na atmosfera, tinha as bases e a motivação necessárias para extrapolar esta mobilidade para o fluxo lento da superfície sólida terrestre, um salto fenomenológico maior nas Ciências da Terra. A tectónica de placas (1962-1969) progrediu a partir do conhecimento das bacias oceânicas para modelo cinemático completo da litosfera à escala global; através do conceito do Ciclo de Wilson a teoria pôde alargar a história da Terra para a evolução dos oceanos, continentes e cinturas móveis ao longo das placas tectónicas. Tornou-se um paradigma para a teoria da Terra como um sistema aberto e dinâmico. 2012-01-01T00:00:00Z
