The International Seabed Authority and the United Nations 2030 Agenda for susta...
Madureira, Pedro; Squires, Dale; Pinto Ribeiro, LuísaDeep sea mining in the Area (seabed and subsoil beyond national jurisdiction) is regarded by some stakeholders as a threat to the achievement of Goal 14 of the United Nations, 2030 Agenda for sustainable development. However, the availability of metals and mineral resources will be crucial to comply with most Sustainable Development Goals. Despite the need to foster a circular economy and reduce waste to a mini...
Factors controlling rare earth element plus yttrium enrichment in Fe–Mn crusts ...
Marino, Egidio; Gonzalez, Javier; Khun, Thomas; Madureira, Pedro; Somoza, Luis; Medialdea, Teresa; Lobato, A.; Miguel, C.; Reyes, J.; Oeserf, M.Marine minerals are important because concentrate in their structure high contents of strategic and critical elements as rare earth elements. Forty-two samples from eight seamounts of Canary Islands Seamount Province (CISP) have been analyzed in order to evaluate their rare earth elements plus yttrium contents (REY). Highest contents of REY are related to hydrogenetic minerals and essentially Fe-vernadite (on a...
VI.2.12 Portugal and seabed mining
Neves, Mariana; Madureira, PedroPortugal is a state party of the UNCLOS and the 1994 Agreement since 3rd November 1997. It was a member of the executive body of the International Seabed Authority (ISA), the Council, between 2001 and 2008 when the regulations for prospecting and exploration for polymetallic sulphides and cobalt-rich ferromanganese crusts in the Area started to be considered. One of the main Portugal’s interests was to pursue t...
Assessment of Cumulative Effects for Environmental Management of Deep-sea Areas...
Radziejewska, Teresa; Madureira, Pedro; Mianowicz, KamilaDeep-sea mining (DSM) is viewed as a nascent industry which, while providing resources necessary for the transition to “green economy,” will make it possible to avoid political and environmental challenges of terrestrial mining. On the other hand, DSM is also perceived as an unwelcome intervention into the deep sea environment and an activity that poses a strong environmental risk as it may be a driver of subst...
Marine Mineral Resources in the Area – Current Regulatory Approaches for Compre...
Madureira, Pedro; Silva, EduardoThe International Seabed Authority (ISA) is the organization through which the current 169 States Parties (plus the European Union) to UNCLOS organize and control all mineral-resources-related activities in the Area for the benefit of humankind as a whole. In so doing, article 145 of UNCLOS provides that ISA has also the mandate to ensure the effective protection of the marine environment from harmful effects t...
TRIDENT – (Technology based impact assessment tool for sustainable, transparent...
Madureira, Pedro; Trident partnersIn its progression towards a transparent and cost-effective system for continuous Environmental Impact Assessment (EIA) and monitoring of exploration and exploitation activities in the deep sea, the TRIDENT project has now reached its 18-month duration. So far, the development of new sensors (Eh, pH, optical dust trap) is well underway, meeting the established goal of presenting novel sensing solutions for deep...
Preliminary deep-sea data analysis collected at Gloria seamount, Azores-Biscay ...
Tojeira, Inês; Pinto Ribeiro, Luísa; Rafael, Teresa; Albuquerque, Mónica; Simões, Maria; Calado, António; Afonso, Andreia; Ramos, Bruno; Souto, MiguelThe present study provides the first results of the exploratory research campaign to Gloria seamount (summit at 45.03°N, 15.54°W), a newly identified seamount in the NE Atlantic. New multibeam bathymetry and an 8 h remote operated vehicle footage and photography data were compiled and analyzed to give the first insights on the geological nature and benthic megafauna assemblages of Gloria seamount. Footage evide...
Contourite depositional systems offshore Madeira Island: Decoding the deepwater...
Roque, Cristina; Hernández-Molina, Javier; Brito, Pedro; Madureira, Pedro; Quartau, Rui; Magalhães, Vitor; Carrara, GabrielaThere is still a great unawareness about the deep-water circulation in the NE-Central Atlantic since the Late Cretaceous. The morphology, sedimentary stacking pattern and distribution of contourite depositional systems have been widely used as paleoceanographic indicators, given clues about the relative velocity and pathways of bottom currents past-circulation. We present here evidence of a new contourite featu...
Deep-Seabed Mining and the United Nations 2030 Agenda for Sustainable Development
Madureira, PedroDespite the warnings that have been repeatedly made by the United Nations’ Secretary-General on the world being decades behind in the transition to clean energy and the risks that humanity is facing regarding climate change and loss of biodiversity, the emission of greenhouse gases into the atmosphere continues to rise. At the same time, the green energy transition has increased the demand for metals used in ba...
CCUS and CO2 transport by ship in Portuguese decarbonization scenarios: from pi...
Mesquita, Paulo; Carneiro, Júlio; Madureira, PedroThe Portuguese target for carbon neutrality by 2050 will require the deployment of CO2 capture, utilization and storage (CCUS). Although Techno-Economic Assessments (TEA) of CCUS scenarios targeting specific industrial sectors have been performed in Portugal in the scope of previous EU projects, the detailed analysis for the early stages of a CCUS chain, focusing on pilot scale, is necessary for policy makers a...
