Diversity of hydrothermal systems on the Portuguese seafloor

An untapped potential for the understanding of deep-sea mineralization


Por Ágata Alveirinho Dias (Institute of Science and Environment, USJ, Macau / Instituto Dom Luiz, FCUL, Portugal).

Abstract: Several hydrothermal fields (HFs) have been identified within the Portuguese EEZ and many more are yet to be discovered, particularly when we consider the extended continental shelf, an area that covers up to 2.4 million km2. The majority of these HFs are located in the Mid-Atlantic Ridge (MAR), where most segments are under the influence of the Azores’ mantle anomaly and the triple junction between the Eurasian, Nubian and North American plates. The first HF was discovered in 1997 (Lucky Strike) whereas the last one (Luso) was discovered in 2018. They revealed a variety of geological settings (e.g., on ridge axis, detachment faults and/or under interference of Azores volcanic anomalies), host rocks (mafic and/or ultramafic) and mineralization processes. A summary of the different types of hydrothermal fields will be presented, with a focus on lower-temperature and less vigorous fields, such as Luso, Menez Gwen and Saldanha. This diversity of HFs makes MAR an ideal laboratory for comparative studies of seafloor hydrothermal systems, which can advance our knowledge of their origin, dynamics and mineralization processes.

Philosophical metatheories have had a great development in recent times. They have been used to reconstruct theories in many different scientific fields, from physics to biology to the social sciences. However, they lack means to systematically test the adequacy of their products.

Cognitive sciences have approached social cognition from two complementary perspectives. On one hand, social psychology and behavioural economics have mostly emphasized mentalizing, social perception, and our ability to model other minds. On the other hand, developmental psychology and motor neuroscience have more focused on imitating, social interaction, and our propensity to coordinate with others’ behaviour.

The course aims at enabling the participants to use different methods to measure the impacts of pollutants on ecosystems. Basic knowledge will be provided through theoretical and practical lessons on how to select and use the most suitable metrics based on the analysis of multiple compartments of the ecosystems.

O evento visa reunir investigadores interessados na aplicação de isótopos estáveis em estudos ecológicos e na utilização de dados históricos de biodiversidade disponíveis em coleções museológicas.

Logótipo e data do evento

“There is often a considerable difference between what we think people need and what people want to use”. This is our perspective on how technology should be developed and will serve as the motto of this event.

The program will consist of plenary lectures, oral, flash and poster communications, and a round table about Science Communication.

This course offers an overview of the different ways to measure biodiversity, and provides tips for the stratification of primary biodiversity data and the construction of variables that describe its various facets. It also includes an in-depth review of the different types of data used to measure biodiversity and their problems and limitations.
