Deep Sea Mining and the possible increase of metals in the water column: how will echinoderms and mussels respond?
2018
Marine pollution has been increasing as a consequence of human activities. In the near future will start the extraction of minerals from ocean depths, Deep Sea Mining (DSM). However, the impacts at the ecosystem level are still unknown. It is necessary to know the effects to contribute to the creation of rules, laws and mining codes that protect and conserve ecosystems and biodiversity. Sea urchin and mussels represents one of the most important seafood product, but also, a sentinel organism for ecotoxicological studies to assess aquatic environments quality. They are directly exposed to anthropogenic contaminants in their habitat. The aim of this study is to understand the influences of tw…
EFFECT OF SUBMARINE ACOUSTIC NOISE IN JUVENILE SEA BREAM (SPARUS AURATA) AND MUSSELS (MYTILUS GALLOPROVINCIALIS)
2018
The earth’ resources are running out, the population will increase and further sources will be needed. These, were found in the deep ocean. To date the mining activities (Deep Sea Mining, DSM) they have not started. One impact of DSM could be underwater noise. Considering the noise frequencies of anthropic activities in the ocean, and the European directive on underwater noise control, we stressed the animals with four acoustic 1/3 band noises around: 63 Hz, 125 Hz, 500 Hz, 1kHz. We study the effects on Sparus aurata juveniles, and on Mytilus galloprovincialis. We will analyse behavioural., molecular and biochemical responses Los recursos de la tierra se están agotando, la población aumenta…
Mining extraction in the ocean depths: a baseline to understand and reduce acoustic impact on biodiversity.
2020
[ES] A lo largo de la historia, el hombre ha explotado los recursos minerales de la tierra para su supervivencia y desarrollo tecnológico sin un equilibrio con su regeneración. Dado el crecimiento de la población mundial y la reducción de recursos, el hombre comenzó a buscar nuevos depósitos que se encontraron en la década de 1960 en las profundidades de los océanos. Con estos, la humanidad empezò a pensar en extraer los minerales de estos depósitos y esto llevò al nacimiento de Deep Sea Mining (DSM). Las consecuencias de las actividades mineras en las profundidades del mar no se conocen realmente y los efectos pueden ser diferentes: contaminación acústica, contaminación lumínica, contamina…
