How North Sea tanker collision could impact Norfolk coastline
Academics have raised fears over the ecological impact the dramatic crash involving an oil tanker and cargo vessel could have on the Norfolk coastline.The two ships – including one carrying jet fuel - went up in flames in the North Sea off the coast of East Yorkshire on Monday.Although the air quality at ground level has been recorded as at normal levels, experts said the event could damage the environment of the protected Norfolk coastline.Environmental biologist Prof Ben Garrod said "we should be doing all we can to ensure this never happens again".
Thirty six people were rescued from the collision and one crew member remained unaccounted for.
Prof Garrod, from the University of East Anglia's School of Biological Sciences, said the coast's shallow bay, The Wash, could be particularly impacted. "The Wash is recognised for its local, national and international ecological importance for flora and fauna alike," he said."Some migrate there, others breed there, and for many species of plants, fungi, and animals, it's home."The possible addition of tonnes of highly soluble toxic material which shuts down the respiration system into such a fragile and important habitat will likely have far-reaching impacts on our local wildlife, especially fish, birds and mammals. "We should be doing all we can to monitor the impact that the release of tonnes of ecologically damaging chemicals has on our fragile marine environment."
The collision occurred at about 10:00 GMT, sparking fires and a mass evacuation, with one crew member saying the incident "came from out of the blue".The Stena Immaculate ship, the US-flagged oil and chemical tanker, was carrying jet fuel on behalf of the US military.The Solong meanwhile, a Portuguese-flagged container vessel, denied that it was transporting 15 containers of sodium cyanide."There are four empty containers that have previously contained the hazardous chemical and these containers will continue to be monitored," said Ernst Russ, the ship's owner.
Dr Paul Johnston, senior scientist at Greenpeace Research Laboratories at the University of Exeter, said he was "very concerned"."The wind is blowing from the north and will drive any material that is released towards the north Norfolk coast," he told the BBC Radio 4 Today programme."There are bird colonies, there will be seals hauled out, dolphins and porpoises passing through the area and animals, together with fish and marine vertebrate."[They will] all be very vulnerable to toxic events, from both oils and chemicals."
'Very, very difficult'
Videos from the scene showed large clouds of smoke billowing out from the tanker, and the firm which managed the Stena Immaculate reported "multiple explosions"."The jet fuel will continue burning [but] the heavy fuel oil is more of a problem if it comes ashore - it will fell beaches and be very difficult to clean up," added Dr Johnston."Any containers that go over the side are likely to be a navigational hazard in so far as any ship that strikes them could become disabled or even sink."When asked if he thought this could result in the largest environmental disaster for a generation, he said it was a "very difficult thing to predict"."And that's why so much effort is being put into salvage efforts in order to minimise the amount of material entering the sea."An ounce of prevention is worth many tonnes of cure but what we can learn from previous events in terms of clean-up is that it is very, very difficult."
Global importance
Prof Alastair Grant, from the University of East Anglia's school of environmental sciences, said "a detailed evaluation" of the environmental risks posed by the jet fuel would need to be conducted. "It contains up to 25% aromatic hydrocarbons, which are relatively toxic and slow to break down in the environment," he said."This makes it approximately 50 times more toxic to aquatic life than diesel oil, which in turn is more toxic than crude oil."
These concerns were also echoed by the Norfolk Wildlife Trust (NWT), which said "any pollution spillage could be devastating" for habitats in the area.A spokesperson said: "Depending on wind direction and contaminants, The Wash and North Norfolk coast, including NWT Holme Dunes nature reserve could potentially be at risk."These areas are home to internationally important populations of seabirds and fragile habitats."We'll continue to keep a close eye on the situation and work with marine authorities if needed."
While the incident happened in UK waters, the responsibility for the investigation will fall to the United States and Portugal.The Marine Accident Investigation Branch, however, is already gathering evidence and undertaking a preliminary assessment of the accident.The Maritime and Coastguard Agency (MCA) is also "rapidly assessing" the potential environment impact of the collision.When it is considered safe to do so, the BBC understands the MCA will deploy equipment to contain and disperse the oil spills.The government agency is also working with the owners of the ships and the Department for Transport to understand potential risks to public health.According to the UK Health Security Agency (UKHSA), any public health risk on shore is deemed to be very low.
'Hugely grateful'
Labour MP Heidi Alexander, the transport secretary, said she was grateful to HM Coastguard, the RNLI and emergency services for their response."They were on the scene swiftly, have helped rescue those in immediate danger and I know they will continue to work tirelessly over the coming days."My thoughts are with all those involved, especially the family of the missing crew member."I am working closely with the MCA as they conduct an assessment of any counter pollution response which may be required over the coming days."

Royal Mail unveil special stamps honouring UK attraction with dual hemispheres
When you stand across the line from this UK spot, you have one foot in the east and one in the west Posting a letter might seem a thing of the past. But whether it's a birthday card, an update from abroad, or just a note of appreciation to a loved one, there are new stamps on the UK market that could fit the bill. Royal Mail has unveiled 10 stamps being issued to celebrate the history and scientific developments achieved at the Royal Observatory in Greenwich, London, since its foundation in 1675. And the attraction has a fascinating feature. The Observatory stands at the Prime Meridian, which divides the Earth into the Eastern and Western Hemispheres. Visitors can stand with one foot in the East and one foot in the West - literally straddling the hemispheres. The Prime Meridian is also the reference point for Greenwich Mean Time (GMT), the basis for all time zones. The main set of six tamps pays home to the the Airy Transit Circle Telescope, Flamsteed House, which is the Great Equatorial Telescope, the largest refracting telescope in the UK, the Annie Maunder Astrographic Telescope, the Prime Meridian where visitors can experience said dual hemispheres, and the Shepherd Gate Clock. A further four stamps, presented in a miniature sheet, honour prize-winning clockmaker John Harrison and his marine timekeepers, ahead of the 250th anniversary of his death next year. The stamps showcase each of Harrison's prototypes for measuring longitude at sea, which became known as H1, H2, H3 and H4. "We are proud to honour the Royal Observatory's 350th anniversary with a set of stamps that celebrate its enduring legacy in advancing our understanding of the universe," said David Gold, Director of External Affairs at Royal Mail. The Royal Observatory was founded by King Charles II in 1675 and was Britain's first state-funded scientific building. The Observatory was founded to provide better star charts that would enhance navigation for global trade. Flamsteed House, the Observatory's original building, became home to ten successive Astronomers Royal who observed the stars and developed new instruments such as the Airy Transit Circle and Great Equatorial Telescope. And what's so special about the Prime Meridian? Well, from the late 19th century, astronomers took thousands of measurements to define the Prime Meridian and establish zero degrees longitude. Their work transformed how we explored our world in an age before smartphones and satellites. Greenwich Mean Time (GMT) was made publicly visible via the Shepherd Gate Clock and its distribution via telegraph signals became an essential part of daily life. Out at sea, Royal Navy surveyors plotted their longitude from Greenwich using chronometers based on John Harrison's revolutionary marine timekeepers. The widespread use by ships worldwide of charts based on the Greenwich Meridian contributed to the international recognition of Greenwich as Prime Meridian of the world in 1884. The stamp images narrate the story of the Royal Observatory and its pivotal role in the history of astronomy, timekeeping, and navigation. The set features specially commissioned artwork highlighting key areas such as notable buildings and significant objects from the collection. Fancy surprising a relative with a good old-fashioned letter? The stamps are available to pre-order from June 5 by clicking here and by telephone on 03457 641 641. A Presentation Pack including all 10 stamps is priced at £17.90. The stamps go on general sale from 12 June. Join the Daily Record WhatsApp community!

Study raises doubt about benefit of low-calorie diet
A new study has found that following a low-calorie diet could increase the risk of developing symptoms of depression, particularly in men and overweight individuals. Canadian researchers analysed data from 28,525 participants in the US National Health and Nutrition Examination Survey (NHANES), noting that nearly 8 per cent reported depressive symptoms. The study found that depressive symptom scores were higher among those restricting calories, which contradicts previous studies that suggested low-calorie diets improve depressive symptoms. Researchers suggest that real-life calorie-restricted diets can lead to nutritional deficiencies and physiological stress, exacerbating depressive symptoms, unlike controlled trials with balanced diets. Professor Sumantra Ray said that the study raises questions about restrictive diets lacking nutrients beneficial for cognitive health and that further well-designed studies are needed.

Following low-calorie diet could make you depressed, major study finds
A new study has found that following a low-calorie diet could increase the risk of developing symptoms of depression. The researchers found that the effects of calorie restriction on mood were more pronounced in men and overweight people. These findings stand in contrast to previous studies which claim low-calorie diets improve depressive symptoms. However, the researchers noted that prior trials included tailored and balanced diet programmes that may not be the same as what people realistically follow in everyday life. For the study, published in BMJ Nutrition Prevention & Health, researchers in Canada used data from the 28,525 people who took part in the US National Health and Nutrition Examination Survey (NHANES) and had completed a health questionnaire relating to depressive symptoms, which gave them a score based on severity. Of the total, 14,329 were women and 14,196 were men. A little under 8 per cent had reported depressive symptoms, while 33 per cent were overweight and 38 per cent were obese. The majority of the group (87 per cent) said they were not on a specific diet, while 2,206 were restricting calories. Some 859 were on a 'nutrient-restrictive' diet, low in fat, sugar, salt, fibre or carbohydrate, and 631 were on diets tailored for the likes of diabetes. Researchers found low-calorie diets were more common among obese patients and those who were overweight. Questionnaire scores for depressive symptoms, such as a low mood, low energy and sleep disturbances, were higher among those restricting calories compared to those who reported not being on a diet at all. The scores were also higher among overweight people following low-calorie diets. Researchers said: 'Numerous studies have consistently focused on 'healthy' versus 'unhealthy' diets. 'They have shown that 'healthy' diets rich in minimally processed foods, fresh fruits and vegetables, whole grains, nuts, seeds, lean proteins and fish have been linked to a lower risk of depression. 'In contrast, an 'unhealthy' diet dominated by ultra-processed foods, refined carbohydrates, saturated fats, processed meats and sweets is associated with an increased risk of depressive symptoms. 'Therefore, individuals must adopt a perfectly healthy dietary pattern to reduce the risk of depressive symptoms. This dichotomy fails to capture the complexity of real-world eating habits.' Restricting calories can lead to deficiencies in protein, vitamins and minerals, researchers suggest, which puts the body under stress. The findings also contradict previous studies showing low-calorie diets improve depressive symptoms. Researchers highlight that these studies were controlled trials, with those taking part following carefully designed and balanced diets. The team said a focus on 'idealised diets' can 'overlook the diversity of dietary patterns', adding: 'In contrast, real-life calorie-restricted diets and obesity often result in nutritional deficiencies, particularly in protein, essential vitamins and minerals, and induce physiological stress, which can exacerbate depressive symptomatology including cognitive-affective symptoms.' Researchers stressed the study has a number of limitations, but gives an insight to how diets recommended by healthcare professionals should be considered for risk factors for depression, especially in men and obese patients. Professor Sumantra Ray, chief scientist and executive director of the NNEdPro Global Institute for Food, Nutrition and Health, which co-owns BMJ Nutrition Prevention & Health with BMJ Group, added: 'This study adds to the emerging evidence linking dietary patterns and mental health, raising important questions about whether restrictive diets which are low in nutrients considered beneficial for cognitive health, such as omega-3 fatty acids and vitamin B12, may precipitate depressive symptoms. 'But the effect sizes are small, with further statistical limitations limiting the generalisability of the findings. Further well designed studies that accurately capture dietary intake and minimise the impact of chance and confounding are needed to continue this important line of inquiry.'
