NASA: North Atlantic ‘Cold Blob’ May be Culprit Behind Ocean Current Slowdown

By Mark Leberfinger, AccuWeather.com Staff Writer
November 17, 2015; 12:34 AM ET

A major player in the transportation of heat in the Atlantic Ocean is slowing down and may affect higher latitude climates in the Northern Hemisphere, according to a NASA analysis of satellite data.

The “cold blob” that developed off Greenland may be the drag on the Atlantic Meridional Overturning Circulation (AMOC) by producing very chilly to record cold water, the National Oceanic and Atmospheric Administration (NOAA) said earlier this year.

Global warming may be responsible for AMOC’s slowdown but natural forces may also be at work, NASA said. AMOC is part of the complex circulation of currents that help take the warmer Gulf Stream water and move it through the basin.

Data from the Gravity Recovery and Climate Experiment (GRACE) satellites correspond with similar findings that were not satellite-based. The GRACE findings were published in the journal Geophysical Research Letters.

An AMOC slowdown would impact other currents throughout the Atlantic.

Tropical Storm Kate is strengthening as it moves away from the Bahamas. This trend is expected to continue due to warm sea surface temperatures and low vertical wind shear.

Kate is not a direct threat to the United States.

(MORE: Follow Tropical Storm Kate With Our Interactive Storm Tracker)

Highlights:

  • Tropical Storm Kate was centered 175 miles north-northeast of the northwestern Bahamas as of Monday night.
  • All tropical storm warnings have been discontinued.
  • The threat of heavy rain and gusty winds in the Bahamas are diminishing.
  • High surf will continue to impact eastward-facing beaches in the northwestern Bahamas.
  • Tropical Storm Kate is not expected to make landfall in the U.S.
  • The latest forecast calls for Kate to become a strong tropical storm and possibly a hurricane before eventually being absorbed by a non-tropical low pressure system midweek as it moves out to sea.
  • Kate is the eleventh named storm of the 2015 Atlantic hurricane season.
  • Kate originally formed as Tropical Depression Twelve Sunday night, and was upgraded to tropical storm status Monday morning.

Tropical Storm Kate formed Monday morning in the Atlantic Ocean near the Bahamas, the National Hurricane Center said. It is unlikely to directly impact the U.S.

As of 1 p.m. ET, the storm had maximum sustained winds of 45 mph and was located 30 miles east-southeast of Eleuthera Island in the Bahamas. Kate was moving to the northwest at 15 mph.

Rain squalls accompanying Kate will graze the eastern islands of the Bahamas into Monday night, AccuWeather said. Tropical storm warnings have been hoisted for portions of the central and western Bahamas, the hurricane center reported.

Auto Start: On | Off

A team of scientists is exploring the darkest corners of a huge underwater volcano in the Caribbean in hopes of better understanding the mysteries of earthquakes and tsunamis, ultimately saving lives.

Kick’em Jenny is a dangerous and active volcano sitting roughly 6,000 feet below the surface of the Caribbean Sea, and located off the coast of the island of Grenada, south of St. Lucia.

Robert Ballard, famous for discovering the Titanic 12,000 feet below the surface of the icy North Atlantic in 1985, set his sights on exploring the Kick’em Jenny to study its eruption history and learn more about how underwater volcanoes can pose a threat.

Ballard, the president of The Ocean Exploration Trust and the director of the Center for Ocean Exploration at the University of Rhode Island’s Graduate School of Oceanography, said the Kick’em Jenny volcano has a history of explosive eruptions, which could have the potential to trigger tsunamis, the effects from which could be felt as far away as the northeastern United States.

Millions of asthmatics unable to breathe as giant cloud of Saharan sand and toxic air covers Britain in layer of smog

  • Air pollution set to hit 10/10 due to dust from Sahara mixing with local pollution and toxic air from Europe
  • Parts of the South Coast, West Country, Midlands and South Wales are worst affected by the problem
  • Dust has been generated from two source areas – one in central Algeria and another in southern Morocco
  • Meteorologists say it’s ‘particularly bad with weather conditions creating “perfect storm” for air pollution’
  • Those in affected areas advised to reduce strenuous outdoor exercise, especially if they get a sore throat
  • Adults and children with lung problems, heart problems and pensioners should avoid vigorous activity
  • Asthma sufferers may have to use inhalers more frequently for a few days until levels drop on Friday
  • But the dust does have positive aspects for fish in the Atlantic Ocean and the Brazilian rainforest

Millions of asthmatics were today having trouble breathing as a potentially-lethal cloud of Saharan sand, toxic air and local pollution sat over Britain.

One sufferer said she felt like she had ‘a baby elephant sitting on my chest’, while another said her lungs felt like they had ‘cobwebs’ inside them.

Even those without health difficulties have been told by experts to reduce outdoor exercise, with air pollution set to hit 10 out of 10 in some areas.

Britons are being warned they may suffer breathing problems, with parts of the South Coast, West Country, Midlands and South Wales worst affected.

Those in affected areas are advised to reduce the strenuous outdoor exercise they do, especially if they start to suffer from a cough or sore throat.

Biological Hazard in France on Wednesday, 26 February, 2014 at 17:39 (05:39 PM) UTC.

Description
Weakened and exhausted by successive storms, more than 21,000 dead seabirds washed up on the beaches of the Atlantic coast since late January, an unprecedented “massacre” for at least a century, announced today the League for the Protection of Birds (LPO). Until February 24, 21,341 dead seabirds are registered in the Basque country in southern Finistère and 2,784 sent in rescue centres. Atlantic puffin and guillemot are the most affected species, and to a lesser extent, razorbill.
Biohazard name: Mass. Die-off (birds)
Biohazard level: 1/4 Low
Biohazard desc.: Bacteria and viruses including Bacillus subtilis, canine hepatitis, Escherichia coli, varicella (chicken pox), as well as some cell cultures and non-infectious bacteria. At this level precautions against the biohazardous materials in question are minimal, most likely involving gloves and some sort of facial protection. Usually, contaminated materials are left in open (but separately indicated) waste receptacles. Decontamination procedures for this level are similar in most respects to modern precautions against everyday viruses (i.e.: washing one’s hands with anti-bacterial soap, washing all exposed surfaces of the lab with disinfectants, etc). In a lab environment, all materials used for cell and/or bacteria cultures are decontaminated via autoclave.

21,000 Birds Killed In France By Slew Of Storms

The Atlantic storms that have buffeted Europe in recent days have killed at least 5,000 sea birds on the French coast, half of them puffins. Most of the birds whose bodies have been washed up on beaches between the Pyrenees and Brittany died of exhaustion or starvation as a result of days of gale-force winds, which made it impossible for them to fish. | XAVIER LEOTY via Getty Images

Thousands of birds have been killed in France. The culprit? Winter storms.

In a statement, the League for the Protection of Birds said that violent storms in January and February were responsible for the deaths of 21,341 birds. The country has apparently not seen a bird “slaughter” that large since 1900, the Agence France-Presse reports.

An initial estimate released earlier this month put the death toll at 5,000. But once the organization enlisted volunteers to help with the count from the start of the month through Feb. 24, the number rose dramatically.

Of the species of sea birds affected, the Atlantic puffin had the highest numbers of deaths, with more than 12,229 deceased found. Large numbers of the common murre (or black guillemot) and razor-billed auk were also killed. The league expects the overall death toll to rise as it continues to track the bodies through the end of the month.

Storms wash up 500 dead seabirds: Bodies of guillemots and razorbills recovered after they died of exhaustion due to the weather

  • Storms over the past month have made it hard for birds to hunt and feed
  • Majority of dead birds were washed up at Chesil Cove in Dorset
  • But numbers pale in comparison to 15,000 puffins found dead in France

Hundreds of seabirds have been washed up along the south-west coast after dying of exhaustion in the recent storms.

The bodies of almost 500 birds, mostly guillemots and razorbills, have been recovered from the beaches of Cornwall, Devon and Dorset after they perished at sea.

Experts at the Dorset Wildlife Trust said consistent gale-force storms in the English Channel during the past month had made it very hard for the creatures to hunt and feed.

The malnutrition coupled with flying in ferocious winds meant they became exhausted and died.

Birds fared even worse across the Channel, where 15,000 puffins were found dead on the shores of France.

The French League for the Protection of Birds said the tragedy could have a devastating effect on the coming breeding season.

The majority of the dead birds have washed up at sheltered Chesil Cove in Dorset, having being swept across Lyme Bay by south westerly winds.

Some conservationists have claimed the birds have been killed by a pollutant similar to palm oil but this has been ruled out by the Dorset Wildlife Trust (DWT).

  • Destroyer and supply ship left Iran last month and are crossing the Atlantic Ocean 
  • Deployment is a response to U.S. naval deployments near Iran’s coastlines
  • Admiral Afshin Rezayee Haddad of Iran’s Northern Navy Fleet said: ‘This move has a message’
  • Ships expected to sail for at least three months

By Associated Press Reporter and Daily Mail Reporter

Iranian warships dispatched to the Atlantic Ocean will travel close to U.S. maritime borders for the first time in a bid to send ‘a message’ to the White House.

A destroyer and helicopter-carrying supply shipbegan their voyage last month from the southern Iranian port city of Bandar Abbas and are on a three-month mission.

The voyage is intended to counter the U.S. naval presence in the Persian Gulf, as the Islamic Republic continues to assert its power across the Middle East and beyond.

‘Iran’s military fleet is approaching the United States’ maritime borders, and this move has a message,’  Admiral Afshin Rezayee Haddad of Iran’s Northern Navy Fleet said, according to
The Jerusalem Post.

‘This move has a message’: Iranian warships dispatched to the Atlantic Ocean last month will travel close to U.S. maritime borders for the first time in response to U.S. fleets near Iran

Haddad said the vessels have already entered the Atlantic Ocean via waters near South Africa, carrying about 30 navy academy cadets for training along with their regular crews.

Iran had first warned America of its plans to deploy its naval forces along U.S. marine borders ‘in the next few years’ in September 2012.

Iran’s Navy Commander Rear Admiral Habibollah Sayyari at the time said that the move would be a response to U.S. naval deployments near its own coastlines. 

The U.S. Navy’s 5th fleet is based in Bahrain, just across the Persian Gulf.

Monster 75 FOOT wave smashes into BRITISH coast: Atlantic superstorm to hit UK TOMORROW

Published: Thu, February 6, 2014

A record wave has just hit Britain but forecasters warn far worse is coming A record wave has just hit Britain but forecasters warn far worse is coming [STEPHAN SLATER]

The largest wave ever seen in British waters was recorded at 3.30am yesterday by a buoy operated by the Plymouth Coastal Observatory at Porthleven, Cornwall.

The beast destroyed the previous record British wave of 67ft and forecasters warned it was only the beginning of 72 hours of storm hell.

It came as experts recommended a TSUNAMI warning system be installed in the Atlantic to protect Britain and Ireland from enormous waves they claimed were ‘increasingly likely’.

The UK was battered by 90mph winds and torrential rain again overnight – but by far the most violent storm forecast in recent times is yet to hit with widespread damage and disruption expected in the coming days.

Parts of a key railway line were destroyed and nearly 10,000 homes were left without power as the brutal weather wreaked havoc yesterday.

Police helicopters were scrambled to help evacuate 150 properties in the Somerset flooding danger zone as David Cameron set up a £100million emergency fund to assist communities in coping with the crisis.

Winds of 105mph were recorded on the Isles of Scilly, off Cornwall while one pub in Chesil Beach, Dorset was completely submerged by a giant 60ft wave.

The latest storms saw Dawlish in Devon bear the brunt of the damage – with shocked locals claiming it felt like “the end of the world”.

Resident Robert Parker said: “It was like an earthquake.

“I’ve been in some terrible storms in the North Sea but last night was just a force of nature.”

Another local, Jeff Deacon, added: “This is surreal. I’ve never seen anything like this. There’s debris all over the road – it’s like a war zone.”

A 100ft stretch of seawall in the town collapsed into the swirling waters, leaving the railway line hanging in mid-air.

Biological Hazard USA State of Georgia, [Jekyll Island Coastal region] Damage level Details

…..

Biological Hazard in USA on Wednesday, 11 December, 2013 at 04:29 (04:29 AM) UTC.

Description
A disease that has killed hundreds of bottlenose dolphins in the mid-Atlantic and southeastern United States has been confirmed in Georgia, state wildlife officials said Tuesday. Four dolphins found dead at Wassaw and Jekyll Islands in November have tested positive for dolphin morbillivirus, Department of Natural Resources officials said. The virus is similar to measles and affects the lungs, brain and immune system of marine mammals. Marine wildlife suffering from morbillivirus may develop skin lesions, brain infections and pneumonia, according to the National Oceanic and Atmospheric Administration. The virus, which follows the seasonal migration pattern of dolphins from the upper mid-Atlantic, is spread through inhalation of respiratory particles or direct contact between mammals, according to the NOAA. The virus can also spread through the eyes, mouth, stomach, skin wounds and the urogenital tract. Department of Natural Resources officials have said they’ve found 23 dead dolphins in Georgia since Nov. 15. The state usually sees 21 dolphins stranded on its shores per year, said state Department of Natural Resources wildlife biologist Clay George. He added that most dolphin deaths seem to be impacting migratory populations and not resident dolphins. Researchers identify dolphin populations by taking photos of their dorsal fins. “Unfortunately, there’s nothing we can do to stop the disease from spreading,” Clay said. “We can only hope that this is part of the natural cycle, and that populations will rebound to healthy levels soon.” Outbreaks of morbillivirus killed harbor seals in the northeast in 2006, according to NOAA. Officials say it also killed dolphins in the northeast from 1987-88 and in the Gulf of Mexico in 1992 and 1994. More than 930 bottlenose dolphins have been found dead or dying on shores stretching from New York to Florida between July 1 and Dec. 1, 2013, according to the NOAA. Officials say the average was about 113 for the same time period between 2007 and 2012.
Biohazard name: Mass. Die-off (bottlenose dolphins)
Biohazard level: 2/4 Medium
Biohazard desc.: Bacteria and viruses that cause only mild disease to humans, or are difficult to contract via aerosol in a lab setting, such as hepatitis A, B, and C, influenza A, Lyme disease, salmonella, mumps, measles, scrapie, dengue fever, and HIV. “Routine diagnostic work with clinical specimens can be done safely at Biosafety Level 2, using Biosafety Level 2 practices and procedures. Research work (including co-cultivation, virus replication studies, or manipulations involving concentrated virus) can be done in a BSL-2 (P2) facility, using BSL-3 practices and procedures. Virus production activities, including virus concentrations, require a BSL-3 (P3) facility and use of BSL-3 practices and procedures”, see Recommended Biosafety Levels for Infectious Agents.

Additional Commentary

The November 25, 2013 M7.0 earthquake (06:27:33 UTC) southwest of the Falkland Islands in the South Atlantic Ocean occurred as the result of strike slip faulting, on either a left-lateral fault striking ENE-WSW, or a right-lateral structure striking NNW-SSE.  The location of the earthquake, near the ENE-WSW trending plate boundary between the South America and Scotia tectonic plates, suggests it is likely associated with left-lateral faulting along this margin. At the location of this earthquake, the Scotia plate moves ENE with respect to South America at a rate of approximately 9.5 mm/yr.

The November 25, 06:27:33 earthquake was the largest of 5 M5+ events that occurred in a similar area over an approximate 2-hour period, including a M5.6 earthquake 24 seconds prior to the M7.0 mainshock. Though this region experiences moderate-sized earthquakes relatively frequently – 15 M5+ events have occurred within 250 km of the November 25 earthquake over the past 40 years – large events are fairly uncommon. The largest nearby earthquake over the same time period was a M6.6 event in September 1993, 210 km to the east of the November 25 earthquake.
