The Scottish Association of Marine Sciences (SAMS) at Dunstaffnage – whose annual Open Day is this Saturday (7th March) – is to lead groundbreaking research commissioned by Scottish Natural Heritage (SNH) and the Scottish Environmental Protection Agency (SEPA).
This three year project will investigate the interaction between tidal turbines and marine life. Its purpose is to assist the Scottish Government to realise the economic and environmental potential of marine renewable energy resources without coming into conflict with protected species.
SNH’s role is to help developers and planners to develop the sector in a way that avoids conflict with protected wildlife and habitats.
The research will specifically focus on the background noise levels in areas being considered for tidal energy development, as well as the noise made by tidal turbines. It will also explore the extent to which marine animals, particularly protected species, can detect and, potentially, avoid colliding with these devices.
SAMS, in collaboration with the European Marine Energy Centre (EMEC) in Orkney, has developed a novel method of measuring sound in areas of strong tidal flow. This expertise is clearly crucial to the project.
In theory it is possible for marine energy developments to impact on some species during construction, installation and operation. However, little is known about what these impacts might be, as there are few devices installed anywhere in the world and little in the way of existing scientific research to refer to. This is the driver of the research initiative announced.
The project underlines the serious engagement of Scotland with renewable energy development in which it intends to be a world leader. The early initiation of such a research will mean that decisions taken by the Governemnt and the planners will be better informed from the outset.
The expertise resulting from the research itself will help to estbalish the authority of Scotland’s position in the field.
SAMS’ Marine ecologist, Dr Ben Wilson, who will be supervising the project, says: ‘This is an exciting opportunity to contribute to both sustainable marine energy extraction and conservation.
‘Scotland is rapidly becoming a magnet for the companies developing devices to capture energy from tidal currents. These
machines however will have to share the sea with vulnerable and protected species like whales, seals and fish. Understanding how these animals will perceive and behave around underwater turbines is a mystery but sound will undoubtedly be the most important sense for them, particularly at night and in murky water.
‘Knowing what the natural sound-scape is like in prospective tidal energy sites and the noise output of different devices will help us identify those devices that marine animals will most easily move around without harm.
‘With this understanding we will be better able to promote those machines that have the most gentle ecological footprints’.
This project is a reminder of the high level expertise existing at SAMS in Argyll. Together with the significant resources here for tidal energy harnessing, this indicates a strong area of future economic development for Argyll.

As For Argyll recently reported, Councillor Dick Walsh, Leader of Argyll and Bute Council, has written to the First Minister, Alex Salmond expressing anxiety about the exclusion of Argyll from the planned upgrade to the National Grid.
This scenario is not something to work up much steam about today because it comes from a thirty year-old document acquired by The Times newspaper – but it does underline, as if we didn’t know, just how dirty and how greedily self-serving politics can get.
Dick Walsh, Leader of Argyll and Bute Council, has written to First Minister Alex Salmond as a matter of urgency. Argyll has been excluded from the planned upgrade to the National Grid.
An indication for Argyll of the depth of interest in marine energy generation is the announcement by the Crown Estate that it has received 38 expressions of interest in leasing parcels of the sea bed in Scotland’s Pentland Firth for marine energy projects. These expressions of interest have come from single companies and from consortia.![Reblog this post [with Zemanta]](http://img.zemanta.com/reblog_e.png?x-id=238c1cd5-9acd-4be2-88ab-2b8c3eb8e6ef)
