US govt to fund study of Marshall Islands nuclear dome water

US govt to fund study of Marshall Islands nuclear dome water,  https://www.rnz.co.nz/international/pacific-news/400433/us-govt-to-fund-study-of-marshall-islands-nuclear-dome-water    The US government has announced US$1.6 million in funding to investigate the water surrounding a radioactive dome in the Marshall Islands.The Runit Dome on Enewetak Atoll was built to contain nuclear waste after US nuclear weapons testing in the Pacific in the 1940s and ’50s.

However, Marshall Islands officials say the lagoon water is already more contaminated than the dome itself, which has been leaking.

The money announced last week will fund a radiochemical analysis of the water surrounding the crater, and an engineering survey of the structure.

Russia’s nuclear torpedoes at the bottom of the sea

A Dead Russian Submarine Armed with Nuclear Torpedoes was Never Recovered, National Interest, Robert Farley, September 15, 2019

Key point: She rests at a depth of 15,000 feet —too deep to make recovery practical. 

The Bay of Biscay is one of the world’s great submarine graveyards. In late World War II, British and American aircraft sank nearly seventy German U-boats in the Bay, which joined a handful of Allied and German subs sunk in the region during World War I. On April 12, 1970, a Soviet submarine found the same resting place. Unlike the others, however, K-8 was propelled by two nuclear reactors, and carried four torpedoes tipped by nuclear warheads.

The Novembers (627):

The November (Type 627) class was the Soviet Union’s first effort at developing nuclear attack submarines…….
 The Novembers were too loud to plausibly find their way into close enough proximity to a NATO port to ever actually fire a nuclear torpedo in wartime conditions…….
On April 8, K-8 suffered two fires, resulting in a shutdown of both nuclear reactors. The boat surfaced, and Captain Vsevolod Borisovich Bessonov ordered the crew to abandon ship. Eight crew members, trapped in compartments that were either flooded or burned out, died in the initial incident. Fortunately, a Soviet repair vessel arrived, and took K-8 under tow. However, bad weather made the recover operation a difficult prospect. Much of K-8’s crew reboarded the submarine, and for three days fought a life-and-death struggle to save the boat. Although details remain scarce, there apparently was no opportunity to safely remove the four nuclear torpedoes from K-8, and transfer them to the repair ship.
Unfortunately, the loss of power onboard and the difficult weather conditions were too much for the crew to overcome. On April 12, K-8 sank with some forty crew members aboard, coming to rest at a rough depth of 15,000 feet. The depth made any effort at recovering the submarine, and the nuclear torpedoes, impractical……
R
The loss of K-8 (along with the several accidents that afflicted her sisters) undoubtedly helped the Soviet Navy learn important lessons about distant operations, if only at extraordinary costs in human lives. And her nuclear torpedoes remain at the bottom, an enduring monument to most dangerous missions of the Cold War. https://nationalinterest.org/blog/buzz/dead-russian-submarine-armed-nuclear-torpedoes-was-never-recovered-80416

Japan says TEPCO will dump more than 1 million tons of radioactive water from Fukushima nuclear plant into Pacific Ocean 

 10 Sept 2019 | Japan’s environment minister announced Tuesday that the country will have to dump radioactive water from the Fukushima power plant into the ocean because it is running out of space, Reuters reported. According to Reuters, Tokyo Electric, or Tepco, has collected more than 1 million tonnes of contaminated water from the cooling pipes used to keep fuel cores from melting since the plant was crippled by an earthquake and tsunami in 2011. “The only option will be to drain it into the sea and dilute it,” the minister, Yoshiaki Harada, told a news briefing in Tokyo…The government is awaiting a report from an expert panel before making a final decision on how to dispose of the radioactive water.

UN warns on need for global action – treaty – as the world’s oceans are in dire trouble

INTERVIEW-Ocean treaty needed to tackle ‘deep trouble’, says UN envoy,  http://news.trust.org/item/20190831063635-oygwk/, by Adela Suliman | @adela_suliman | Thomson Reuters Foundation, Saturday, 31 August 2019 The oceans are increasingly threatened by global warming, acidification and pollution, and the impacts will affect us all, warned the U.N. oceans envoy. By Adela Suliman

STOCKHOLM, Aug 31 (Thomson Reuters Foundation) – The world’s seas are increasingly threatened by global warming, acidification and pollution, making it crucial to agree on a global treaty to protect them, the U.N. oceans envoy said.

Peter Thomson warned in an interview with the Thomson Reuters Foundation that the oceans were “in deep trouble”.

“It is worse than we think and there are no easy solutions,” he said at World Water Week in Stockholm this week, as the latest round of talks on a treaty wound up in New York.

The first global ocean treaty is due to be agreed in the first half of 2020. But on Friday environmental group Greenpeace said the negotiations were “disappointing” so far, blaming a lack of political will to secure a “progressive outcome”.

Thomson said a “comprehensive global regime” was needed to accelerate action to protect waters beyond national jurisdictions.

“It is critical in these challenging times for planetary environmental conditions that we develop a binding treaty for the conservation and sustainable use of marine biodiversity in the ocean,” he said.

A flagship scientific report warned this year that two-thirds of the ocean area was already affected by growing human impacts, primarily from stressors linked to global warming.

Climate change and the oceans were “intimately linked”, Thomson said, adding humanity was on a “totally irresponsible course” by not tackling global warming urgently enough.  In 2015 nearly 200 nations signed up to the Paris Agreement that aims to keep the rise in average global temperatures to “well below” 2 degrees Celsius (3.6F) above pre-industrial times, and ideally to 1.5C.

“(Climate change) is going to have huge human impact and there will have to be a change of occupations, a change of domiciles,” Thomson warned.

Fishing communities and coastal dwellers would be worse off and needed support to adapt in a warmer world, he added.

A set of global development goals to be met by 2030 include conserving and using oceans, seas and marine resources wisely.

Much of the planet’s rainwater, drinking water, food and weather systems are provided or regulated by the sea.

“Every second breath you take comes from oxygen from the ocean,” said Thomson, a Fijian diplomat.

But seawater warming and acidification could change the chemical composition of the oceans, with profound effects for humans, he warned.

TURNING THE TIDE?

Pollution, including plastic, industrial waste, sewage and fertiliser, poses a serious threat to marine life, Thomson said.

“There are over 500 ‘dead zones’ all over the world where actually no life exists because of what’s coming down those rivers by way of pollution,” he said.

Meanwhile, irresponsible fishing practices have depleted fish stocks and are “part of the human tragedy of ending biodiversity”, he added.

Billions of people depend on oceans for their food and livelihoods, but the U.N. Food and Agriculture Organization has said nearly 90% of fish stocks are over-fished or fully exploited as global demand rises.

Thomson said, however, that pollution and over-fishing were “very fixable” with better environmental management.

Individual action had begun to make inroads – from public beach clean-ups to how people shop and vote.

Climate change, on the other hand, was a more “pernicious” threat to the Earth’s water, he said.

The U.N. climate science panel is due to publish a special report in late September on how climate change is affecting the world’s oceans and frozen water. Thomson said it would be a “guiding light” for future international protection efforts by providing scientific insight on how global warming is affecting life in the sea.

“The report will no doubt provide further support for dramatic scaling up of political ambition (to act),” he said.

“It’s no time to be sitting around philosophising … The changes have to be made now

Sea level rise only half the story – climate change is altering ocean waves

Climate change may change the way ocean waves impact 50% of the world’s coastlines  The Conversation, Mark Hemer, Principal Research Scientist, Oceans and Atmosphere, CSIRO, Ian Young. Kernot Professor of Engineering, University of Melbourne, Joao Morim Nascimento, PhD Candidate, Griffith University, Nobuhito Mori, Professor, Kyoto University, August 20, 2019    The rise in sea levels is not the only way climate change will affect the coasts. Our research, published today in Nature Climate Change, found a warming planet will also alter ocean waves along more than 50% of the world’s coastlines.

If the climate warms by more than 2℃ beyond pre-industrial levels, southern Australia is likely to see longer, more southerly waves that could alter the stability of the coastline.

Scientists look at the way waves have shaped our coasts – forming beaches, spits, lagoons and sea caves – to work out how the coast looked in the past. This is our guide to understanding past sea levels.

But often this research assumes that while sea levels might change, wave conditions have stayed the same. This same assumption is used when considering how climate change will influence future coastlines – future sea-level rise is considered, but the effect of future change on waves, which shape the coastline, is overlooked.

Changing waves

Waves are generated by surface winds. Our changing climate will drive changes in wind patterns around the globe (and in turn alter rain patterns, for example by changing El Niño and La Niña patterns). Similarly, these changes in winds will alter global ocean wave conditions.

Further to these “weather-driven” changes in waves, sea level rise can change how waves travel from deep to shallow water, as can other changes in coastal depths, such as affected reef systems.

Recent research analysed 33 years of wind and wave records from satellite measurements, and found average wind speeds have risen by 1.5 metres per second, and wave heights are up by 30cm – an 8% and 5% increase, respectively, over this relatively short historical record.

These changes were most pronounced in the Southern Ocean, which is important as waves generated in the Southern Ocean travel into all ocean basins as long swells, as far north as the latitude of San Francisco.

Sea level rise is only half the story.…. https://theconversation.com/climate-change-may-change-the-way-ocean-waves-impact-50-of-the-worlds-coastlines-121239

Anxiety over Russian nuclear power plant afloat in Arctic

The radioactively polluted oceans

Radionuclide-Inundated Oceans    https://www.opednews.com/articles/Radionuclide-Inundated-Oce-by-ed-tanner-Ocean-Acidification_Ocean-Currents_Ocean-Energy_Ocean-Pollution-190712-791.htmlOpEdNews Op Eds 7/12/2019 By ed tanner Only God knows how much radioactive waste has run off, from the continental United States and Asia, into the oceans. Only the gods know how many barrels of nuclear waste from countries like France, the USA, and Russia have been carted out on freighters into the Atlantic and Pacific Oceans and dumped. The French blew up a Greenpeace ship by New Zealand for dogging one of France’s nuclear-waste dumping freighters.

The Russians continue to have the least-contained, most-dangerous reactor designs in the world running on undependable mox [a type of nuclear fuel] made in Mayak. Two Russian reactors may have already gone off since Chernobyl. You will not hear about that. There were elevated radiation readings in Europe, since Fukushima, that came from Russia and stunk of high-level reactor releases.

Busby used a gamma spectrometer off the coast of the Baltic Sea by Russia and found that cesium 134 and 137 levels were twice as high, post Chernobyl, as they should be, in 2017.

America is a radioactive crudhole with places like Hanford, Three-Mile Island, and multiple open-air nuclear tests for decades. Ninety-seven of the leakiest, oldest, most cracked and brittle nuclear reactors in the world. Tens of thousands of tons of the worst high-level nuclear waste are spread across the USA.

Now think about Russia and Japan and the Arctic ocean and Pacific ocean for a minute.

Many places in Russia are so radioactive that one cannot stand for 30 minutes without dropping dead. Russia has the distinction of being one of the most radioactive countries on earth! Up there with Japan and many places in America.

The CIA will tell you about Russia’s shrinking demographics, but they will not tell the truth about it.

Half the men and women in Russia have fertility problems from massive radionuclide contamination. The CIA says it is from an aging Russian population and bad Russian economy. I knew a Russian doctor that was in a port where a Russian sub blew in the late ’80s. She has had dysmenorrhea and has been bleeding since then.

The Russians run nuclear-powered ice breakers in the Arctic. America is a radioactive shithole and so is Russia. The Russians have dumped two hundred thousand tons of high-level nuclear waste in the Arctic ocean. That includes the old nuclear reactors it has pushed into the Arctic and Baltic oceans and the old nuclear submarines there. Altogether there are probably a half a million tons of the highest-level radionuclides dumped in the Arctic ocean, from Russia, the USA, France and England. Some of that high-level waste is constantly changing. Some has longer lasting, heat-generating radionuclides like pyrophoric plutonium

Uraniums

Strontiums THESE ARE STRONG

Cesium 134-137 BETA-GAMMA

Radioactive-cobalt EMITTERS

Germanium-72, 73, 74, 76

Arsenic-75

Strontiums 88-90

Iodine 129

Yttrium-89

Zirconium-90 to 96

– Advertisement –

Niobium-95

Technetium-99

Ruthenium-101 to 106

Things like strontium 90, plutonium and

CESIUM 134-137 are migrating to the Pacific ocean from the Arctic ocean, so there is the Fukushima nuclear excrement in the Pacific and everything else.

The Russians brag about a floating reactor in the Arctic. That crappy old reactor will dump nuclear waste into the ocean and forever be prone to exploding there. The Russians have dumped old nuclear submarines and old reactors in the Arctic ocean. Americans and the UK and France have dumped subs into the oceans too.

THIS SUNKEN NUCLEAR SUB IS LEAKING RADIATION INTO THE OCEAN

Trip to check radiation after 1989 sinking of Russian sub 

AP News July 5, 2019  COPENHAGEN, Denmark (AP) — A joint Norwegian-Russian expedition will assess whether a Russian submarine that sank 30 years ago is leaking radioactive material, Norwegian authorities said Friday.

The Radiation and Nuclear Safety Authority say Norwegian research vessel G.O. Sars will set off Saturday from Tromsoe, northern Norway, to the Arctic Barents Sea where the Komsomolets submarine sank in 1989. Forty-two of the 69 crewmen died in a fire, and the submarine’s nuclear reactor and two nuclear warheads are still on board.

The agency said a Norwegian-built remote-controlled submersible would be used and the work “would be demanding” as the submarine “lies deep” at about 1,700 meters (5,610 feet)…… https://www.apnews.com/dd6e18dafde14bf799de6d9b5f13fccd

A devastating threat to the marine ecosystem – the Impact of Ocean Acidification

What Is the Impact of Ocean Acidification? https://www.envirotech-online.com/news/water-wastewater/9/breaking-news/what-is-the-impact-of-ocean-acidification/49250  Ocean acidification could have a massively damaging impact on millions of people all over the world in the coming years and decades, according to a new study from the University of Plymouth. By concentrating on heavily acidified hotspots in Japan and the Mediterranean, the study’s authors claim they can predict what may happen on a global scale if carbon continues to seep into the sea.The study is just latest in a growing body of work from its two authors, who have demonstrated that acidification can have a potentially devastating effect on marine ecosystems, with reefs under particular threat. This not only endangers the coral and oysters which comprise the reefs themselves, but also the myriad fish, crustaceans and other marine organisms which call them home.

What is ocean acidification?

Ocean acidification can be defined by a fall in pH levels in the water, caused primarily by carbon seeping into their vicinity. This can be caused naturally by volcanic fissures, such as at the two sites monitored by the study’s authors, but is becoming more and more commonplace through anthropomorphic activity, given that we release around a million tonnes of CO2 into the atmosphere every hour.

Roughly one quarter of that amount finds its way into the ocean and dissolves; once that happens, it reacts with the salty seawater to create a weak acidic substance. This causes surface ocean water to experience a fall in pH levels of approximately 0.002 units per year. That might not sound like much, but cumulatively it could have a sizable impact on the harmony of the water upon which so many marine creatures depend to survive and thrive.

Reefs at risk

The warming temperatures of the world’s oceans have already done significant damage to marine reefs; one only need to look at what’s happened to the Great Barrier reef for confirmation. As if that wasn’t bad enough, the acidification studied by Professor Jason Hall-Spencer and Dr Ben Harvey has been found to further jeopardise their longevity, especially for those composed of oysters or corals, which are particularly sensitive to the acidic effect.

The degradation of reefs not only spells trouble for the corals themselves, but also for the more than 25% of all marine animals which use them as a habitat. As well as being a hammer blow for biodiversity, this could also deplete stocks of many varieties of fish and shellfish which are popular for human consumption. Finally, reefs also provide an important breakwater for coastal communities; losing them would mean reduced protection against extreme weather events at sea.

What can be done?

In a world in which our seas and oceans are already suffering from myriad different problems, such as plastic pollution, dangerous blue green algae, habitat disruption from shipping, oil spills and many more, the last thing that the Earth’s waterways need right now is another threat in the form of increased oceanic temperatures and acidification. As a result, the lead author of the study Professor Hall-Spencer has called for immediate action.

“The Paris Agreement on climate change was welcome, but it does not mention ocean acidification, nor the fact that this rapid change in surface ocean chemistry undermines the social, economic and environmental pillars of sustainable development,” he remarked. “The time is ripe for a ‘Paris Agreement for the oceans’, with the specific target to minimise and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels.”
