Europe’s seas are home to a rich and diverse array of species, habitats and ecosystems. Although vital for Europe’s economic and social wellbeing, many of these ecosystems risk being irreversibly damaged by human activities. ‘Marine messages’, a briefing from the European Environment Agency (EEA), provides an overview of the current state-of-affairs of European seas and our use of them. It argues that economic activities including transport, fishing, offshore energy and tourism should be better managed so that they ensure sustainable health of marine ecosystems.
Oceans of Energy
Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water could also be used to turn electricity-generating turbines. But dams erected with electrical turbines blocked waterways,...
Harnessing marine renewable energy from Poole Harbour: a case study
Global warming and its impact on our environment, society and economy is one of the fundamental concerns of our time. In response, the UK Government has implemented numerous targets including the 80% reduction in greenhouse gas emissions on 1990 levels by 2050, and the increase of renewable energy to 15% by 2020. In order to contribute towards these targets, the government may seek to harness the UK’s high marine and coastal renewable energy potential. Located in Southwest England, Poole Harbour provides strong...
The MAGnificent Seven - Gunning for Marine Waste
Waste Management World focused this article on Terragon Environmental Technologie`s product, MAGS (Micro Auto Gasification System) and the solution it provides to the maritime sector. MAGS transforms solid waste and sludges into energy which can be intergrated at the site where waste is generated. New regulations from MARPOL Annex V came into effect on January 1, 2013 - virtually banning the discharge of waste into the sea. This causes vessels` to store waste onboard or burn it in polluting incinerators. Read the...
Is marine energy about to go mainstream?
Why the costs of wave and tidal power could soon plummet - viewpoint from Dr Stephen Wyatt, Head of Technology Acceleration, Carbon Trust As the marine industry gathers in London for its annual get together one thing is clear; the sector is growing up fast. So fast that it looks like it will soon be defying its critics and getting its feet seriously wet after many years of tests, tanks and prototypes. A fresh optimism is running through the fledgling industry. The holy grail of marine energy could soon be...
Marine and coastal environment
Although not always immediately apparent, our wellbeing as humans is affected by the environmental state of our seas, because many aspects of our lives benefit from the goods and services provided by well-functioning marine and coastal ecosystems. These ecosystem services offer a multitude of opportunities to provide an income for people for instance through production of fish and shellfish for human consumption or an environment suitable for tourism and recreation. Environmental impacts in European seas, which...
