Scotland’s whales at risk from military exercises in 2010
The intrepid field team of Sarah, Nicola and Kila are dusting off our field equipment in preparation for Joint Warrior 101. WDCS have renewed their call for a full and transparent Environmental Impact Assessment to be conducted by the Ministry of Defence for the exercise.
Joint Warrior, set to start on April 12th, is a major exercise led by the UK and involving up to 12 NATO and Allied Nations. At-sea operations are conducted for two weeks and occur twice every year. Up to 85 aircraft, 22 ships and 3 submarines operate during this massive international exercise. Military sonar, used during the exercises, emits intense loud noise that can disturb and harm whales and dolphins, which rely on their sensitive hearing to navigate, find food and communicate. Naval sonar, more commonly linked to mass strandings events of deep diving whales, has also been associated with minke whale strandings in the Bahamas and in North Carolina. On the west coast of US, close to Seattle, similar rapid fleeing behaviour has been observed from killer whales and dolphins in response to sonar.
The west coast of Scotland is well-known for its populations of minke whales which migrate to the area in the summer months to feed in the rich and productive waters. Decreases in sightings of minke whales have already been reported off the west coast of Scotland during naval activities. It is not known how any disruption in the whales’ feeding behaviours will affect populations in the long term.
HWDT and WDCS have joined forces to monitor important whale habitat in the Minch, western Scotland, during the Joint Warrior exercise as a result of ongoing environmental concerns. WDCS has been conducting land-based whale and dolphin observations in northwest Scotland, whilst HWDT has been surveying from its dedicated research vessel, Silurian, using visual and acoustic techniques.
Western Scotland is one of the most important marine habitats in Europe. We are concerned about the potential impacts that these massive and regular exercises, including Exercise Joint Warrior, are having on our marine wildlife. The UK Ministry of Defence should conduct a full and transparent Environmental Impact Assessment – like those currently being undertaken by the US Navy – as a matter of urgency.
Watch this space! We will begin blogging proper on Saturday 10th April.
