Ocean exploration benefits NOAA and the nation


Consider that we have explored only five percent of our ocean,
meaning that 95 percent of what lies beneath remains unknown.
The NOAA Office of Ocean Exploration and Research is the only federal organization currently dedicated to exploring our unknown ocean.
From our skilled staff to our tools and technologies and our ability to deliver data accurately and fast, our unique capabilities are helping to advance knowledge and understanding needed to help citizens, businesses, and governments make smart choices to protect lives, property, and economic wellbeing.
There's a lot of exploration left to do...who's with us?!

From NOAA by Alan P. Leonardi

Fiscal year 2014 continued a tradition of excitement and productivity for NOAA’s Office of Ocean Exploration and Research (OER).
It was a year of accomplishments that advanced our understanding of the ocean.
In my view, there are several ocean exploration matters of particular importance.
First, we have a national need to explore the ocean.
NOAA is often described as the nation’s “environmental intelligence agency,” and exploration is the vital first step in gathering ocean intelligence.
OER is the only federal organization systematically exploring our largely unknown ocean for the purpose of discovery and the advancement of knowledge.
Despite the fact that it covers 71 percent of our planet’s surface and supports countless forms of life in and out of the water, much of Earth’s ocean remains unexplored.

Second, we acknowledge that OER’s exploration record is studded with accomplishments.
Those accomplishments are recorded in this and past annual reports, on our website, and in scientific journal articles based in whole or in part on OER expeditions and projects.

  NOAA Ship Okeanos Explorer: Gulf of Mexico 2012, Spectacular New Shipwreck Discovery

They reflect the leadership, expertise, and hard work of the OER team, but also the shared knowledge, planning, funding, equipment, technology, and staffing of our many valued partnerships, including other NOAA offices, federal, regional and state agencies, educational and oceanic institutions, industry, and not-for-profits.
Exploring deep-ocean frontiers is too expensive and challenging for any single organization, and partnerships move us all forward with a sense of collaboration and community.

Third, we must always consider the value of ocean exploration and our accountability to a critical stakeholder: the taxpayer.
With our partners, NOAA’s ocean exploration team acquires and shares crucial data that benefits science and the economy by enabling policymakers and resource managers to make informed decisions about how to best use and protect the ocean and all it contains.

With each technology advanced and expedition undertaken, OER fills in knowledge gaps about deep-ocean areas, stimulates research and new lines of scientific inquiry, and provides high-value environmental ocean intelligence not available elsewhere but needed to address both current and emerging needs.
These are the returns on investments OER provides to taxpayers.

 Know your ocean

I begin my tenure as OER’s new director firmly believing in the vital importance of our work.
This report chronicles work that OER and our partners have accomplished together, for the great benefit of NOAA and the nation.
We also recognize that much work and discovery still lie ahead.
Our future will be filled with new and continued partnerships and advancements in obtaining and sharing information.
This includes the possibility of using telepresence in new ways to allow scientists ashore to participate virtually in research at sea.

OER is well known as a reliable partner and source of knowledge, yet it also thrives on incremental and transformational change, improvement, and innovation.
This balance allows us to sail toward a future bright with potential, and I look forward to bringing you news of our progress in 2015.

Does metal found in a 2,600-year-old shipwreck prove that Atlantis DID exist? Mythical red alloy said to be from the lost island is discovered off coast of Sicily

The shipwreck with the ingots was found 1,000 feet
off shore of the town of Gela in the sourthern part of Sicily
Gela with the Marine GeoGarage

From TheDailyMail by Richard Gray
  • Marine archaeologists found 39 ingots of 'orichalcum' off the town of Gela
  • They were discovered on the sandy sea floor in a wreck under 10ft of water
  • Experts say they are the mythical metal Plato claimed was from Atlantis
  • Analysis has shown they are an alloy of copper, zinc, lead, iron and nickel
  • Shipwreck is a 2,600 year old cargo vessel thought to be from Greece
  • Researchers believe it was sunk in a storm just 1,000 feet from shore
A mythical metal said by ancient Greeks to be found in the lost city of Atlantis has been recovered from a ship that sunk 2,600 years ago off the coast of Sicily.
Marine archaeologists found 39 ingots of what they believe is 'orichalcum' on the sandy seabed among the wreck of a trading vessel that sank 1,000 feet off the coast of the town of Gela, in southern Sicily.
The wreck is the fifth ancient ship to be recovered off the coast of the town.

One of the lumps of 'orichalcum' that was found on the seabed just off the coast of Gela, in southern Sicily
The metal found on the sea floor off Sicily (above) was found to be an alloy of copper, zinc, lead, nickle and iron

Professor Sebastiano Tusa, an archaeologist at the office of the Superintendent of the Sea in Sicily, claimed the metal they had discovered in the remains of the ship was probably the mythical and highly prized red metal orichalcum.
Analysis of the metal ingots revealed they were made from an alloy of copper and zinc with traces of nickel, lead and iron.
Professor Tusa told the Mail Online that the X-ray fluorescent analysis of the metal had confirmed that it was orichalcum.
He said: 'The discovery is unique and exceptional because it is the fist time that we find oricalcum ingots.'
Speaking to Discovery News, he added: 'Nothing similar has ever been found.
'We knew orichalcum from ancient texts and a few ornamental objects.
'The wreck dates to the first half of the sixth century.
'It was found about 1,000 feet from Gela's coast at a depth of 10 feet.'
If the metal discovered by Professor Tusa and his team is really the mythical orichalcum, then it lends support to the idea of Atlantis as being a real place.

 Statues like this one above from the sunken Egyptian city of Heracleion have recently been rediscovered by marine archaeologists, raising hopes that if Atlantis did ever exist then it may still be found under the sea

The existence of the island is greatly debated among historians and archaeologists.
Some believe it is entirely fictional while others claim stories of the 'Island of Atlas' may have been based on a real historical location that was drowned by rising sea levels or a tsunami.
The Egyptian city of Heracleion, for example, was lost 1,200 years ago when it was engulfed by the sea.
Most of the legend of Atlantis comes from the work of the Greek philosopher Plato, who describes how the great nation was submerged beneath the Atlantic Ocean after falling out of favour with the Gods.
Plato mentions orichalcum in the Critias dialogue and describes Atlantis as flashing with the 'red light' of the metal.
He wrote that orichalcum was highly prized and second only in value to gold. It was mined in the mythical island and covered the surfaces of Poseidon's temple.
The existence of this metal and its composition has since been widely debated, but it is commonly thought to be a brass-like alloy. Brass is made from copper and zinc.
It is thought to have been made through a process called cementation, which reacts zinc ore with charcoal and copper in a crucible.

This map of Atlantis - oriented with south at the top - was drawn by 17th century scholar Athanasius Kircher, who pinpointed the mythical continent as being in the mid-Atlantic before it was lost to the sea

X-ray fluorescence of the ingots found off the coast of Gela show they were made from 75-80 per cent copper, 15-20 per cent zinc and small amounts of nickel, lead and iron.
Professor Tusa told the Mail Online: 'The shipwreck is dated to the beginning of 6th century BC.
'We cannot say how big is the vessel because we have to dig into the sand to recover what it is left of the wooden hull. But I presume that she was about 15 metres (49 feet) long.
'It is a new shipwreck unknown before this discovery.'
'She was sailing to Gela and was entering the harbor situated at the mouth of river Gela.
'Probably during the entrance there was some mistake in the maneuvering because of heavy sea and the ship went into the sandy beach'
Professor Tusa said that they also found some Greek vases, a terracotta figure of the Goddess Demeter and some wood in the wreck.
He added: 'The finding confirms that about a century after its foundation in 689BC, Gela grew to become a wealthy city with artisan workshops specialised in the production of prized artifacts.'

Putin makes his first move in race to control the Arctic

Northern Fleet: Vladimir Putin rides in a submersible vessel in the Baltic Sea as Russia announces the resumption of its presence in the Arctic, a project that had been abandoned by the military after the fall of the USSR.

From Newsweek by Elisabeth Braw

In November, the Russian K-550 nuclear ballistic submarine Alexander Nevsky, submerged in the Barents Sea between Russia and the North Pole, successfully launched a missile that travelled its prescribed course to Kamchatka in Russia’s far east.
The Alexander Nevsky thus joins two other Russian nuclear submarines, which have, in the course of the autumn, conducted successful ballistic missile tests.

Russian nuclear submarines have long been based in Arctic waters, just as the United States keeps its fleet in the Atlantic and Pacific oceans.
Still, the missile tests from the icy region sent a chilly message.
The Alexander Nevsky and its brothers – the Vladimir Monomakh and the Yuri Dolgorukiy – belong to Russia’s new Borei-class nuclear submarine fleet, which can carry up to 20 of the country’s new Bulava nuclear missiles.
With its payload of 10 nuclear warheads capable of travelling up to 8,000 kilometres – the distance between, say, Moscow and Chicago – the Bulava is a fearsome weapon.
“Because of the Ukrainian situation, the West is reluctant to take into account that Russia is a nuclear power that’s investing heavily in its nuclear arsenal,” says Pavel Baev, a professor at the Peace Research Institute in Oslo and a former researcher at the then-Soviet Ministry of Defence.
Mighty though they may be, the Borei-class submarines aren’t much larger than the ageing vessels they’re replacing.
“You could argue that a few new nuclear submarines don’t make a difference,” says Baev.
“But Putin is engaging in nuclear brinksmanship. It’s a dangerous game that the West is reluctant to get involved in, and he seems to be betting that that will give him the upper hand.”
Though all five official nuclear weapons states – United States, Russia, France, Britain, China – are modernising their arsenals, Russia’s overhaul of its vast Soviet-era range is particularly ambitious.

 Cape Schmidt with the Marine GeoGarage

Nuclear brinksmanship aside, the military giant has embarked on a mission to leave footprints in the Arctic.
In October, defence minister Sergei Shoigu announced that Russia will deploy military units along its entire Arctic coast, “from Murmansk to Chukotka” (a distance of 4,700 kilometres).
The armed forces have begun building military facilities on Cape Schmidt in Russia’s far east and on the country’s Arctic Wrangel Island and Kotelny Island; next year the country is scheduled to open an airport at Cape Schmidt.
Earlier this year it reopened its northern Alakurtti military base near the Finnish border (featuring 3,000 soldiers), and on 1 December president Vladimir Putin announced that Russia’s Arctic command has become operational.

The concept of an Arctic race memorably introduced itself when Russian explorers planted a flag on the Arctic seabed in 2007.
Since then, cooperation has been taking precedence.
“But now the Arctic race is heating up, primarily because of Russia,” notes Baev.
“These sharply-increasing military activities don’t make much sense considering that Ukraine is Russia’s military priority right now, but the Arctic isn’t just Putin’s pet project. The Arctic is the one neighbourhood in the world where Russia feels strong.”
(Russia’s Arctic command did not respond to an interview request.)

It’s also the one neighbourhood in the world that has large untapped energy resources: some 22% of the world’s undiscovered oil and natural gas, according to the US Energy Information Administration.
With climate change making the Arctic ocean’s resources more accessible, energy giants from Statoil to Rosneft are testing the waters.
The melting ice is also making regular shipping more realistic.
Last year 71 ships carrying 1.4 million tonnes of cargo traversed the Arctic northern sea route – which cuts the travelling time from Shanghai to Hamburg by 30% – escorted by Russian icebreakers. “But most international shipping companies don’t favour the Arctic, and China’s massive new container ships can’t get through there,” explains Duncan Depledge, an associate fellow specialising in Arctic geopolitics at the RUSI, a London think tank. Indeed, the 71 Arctic transits pale compared to the 16,596 transits through the Suez canal last year.
But Sweden and Finland, home to regions north of the Arctic circle, are sensing opportunities and have opened Brussels offices promoting industrial development.
Even Poland has launched a GoArctic campaign.

Near the North Pole, as in the Middle East, oil and the military go hand in hand. “In the Arctic, Russia is the undisputed number one,” observes Katarzyna Zysk, an associate professor at the Norwegian Institute for Defence Studies.
“But Norway is trying hard to assert its role, especially since the high north plays a significant role in its economic and defence policy. Denmark and Canada are active too, and interest is increasing in the United States as well. These developments are closely followed by Russia, especially given the current tensions with Nato.”

Yet the reopened military bases may be more peaceful than they seem.
“All activities in the Arctic need some sort of security aspect,” says Depledge.
“In much of the Arctic, the military is the only institution that can perform that constabulary function.” 

Here’s the catch: if one country makes military moves, its competitors respond.
Norway, Russia’s closest Arctic neighbour and home to Nato’s first Arctic military operations centre, has been moving troops and equipment north, and prime minister Erna Solberg recently announced that Arctic concerns have caused the country to keep its fighter jets at home rather than sending them on Isis-fighting missions.
In December, Norway introduced an extremely advanced spy vessel that will patrol its Arctic waters.

Indeed, if a second cold war unfolded, the front line would be not just along the Baltic states but right here in the Arctic, between Norway and Russia.
“Russia’s military actions on the European side of the Arctic worry Denmark as well as other Arctic nations,” reports Rear Admiral Nils Wang, commandant of the Danish Defence College and one of the country’s leading Arctic experts
 “Though its reopened military bases also have a coastguard function, Russia is using them to send a strong message to the world and its own citizens that it will defend its Arctic presence if necessary. But the Arctic resources both off-shore and on-shore have already been allocated to the five Arctic coastal nations, so a conflict in the Arctic would more likely be a spillover from conflicts elsewhere, for example Ukraine.”
Denmark, too, has a new Arctic command, while Canada – long an aspiring Arctic superpower – makes its presence known by regularly dispatching naval vessels carrying Canadian flags and sometimes government ministers. 

 Area of the continental shelf of the Russian Federation in the Arctic Ocean
beyond 200-nautical-mile zone

One third of the Arctic is land; one third icy international waters; and one third shallower waters located on continental shelf.
While international law gives the five Arctic nations exclusive economic zones in the waters off their Arctic coasts, the resource-rich continental shelf has become sought-after international real estate. Recently Russia’s natural resources minister Sergey Donskoy announced that 1.2 square kilometres of hydrocarbon-rich continental shelf should belong to Russia.
The country, Donskoy said, will apply to the UN Commission on the Limits of the Continental Shelf (CLCS) for a continental shelf extension next spring.
(A Russian application submitted to the CLCS in 2001 was rejected due to insufficient evidence.) Last year, Canada filed a similar application with the CLCS, claiming rights to 1.7 million square kilometres of Arctic continental shelf.
And in early December, Denmark submitted a CLCS application asserting that it owns the North Pole itself.

Given that International Energy Agency predicts a 35% rise in global energy demand between 2010 and 2035, the quest for the Arctic makes perfect sense.
“Right now, with global energy prices low, it’s not very profitable to invest in Arctic energy exploration, but as far as Russia is concerned, it will remain interested whatever happens,” explains Zysk.
“The Russians feel that they have to move to the Arctic ocean to secure their energy future, and their military presence protects the country’s economic interests. They’re essentially saying, ‘we’re here’.”

That economic potential could spell doom for the Arctic. According to Greenpeace, “inevitable” oil spills would irreversibly harm the pristine region’s polar bears, seals, whales and fish.
“And who would clean up after an oil spill?” asks the environmental group’s Arctic campaigner Charlie Kronick.
“In the Gulf of Mexico, BP was able to deploy hundreds of ships and thousands of workers, and the Macondo well still released around four million barrels of oil.  Because the Arctic has none of the infrastructure or facilities available in the Gulf of Mexico, an oil spill would provoke an international incident when the oil starts travelling underneath the ice.”

Indeed, in spite of global warming, the northernmost continent on earth remains immensely cold.
As Putin made his Arctic command announcement, thermometers on Kotelny Island recorded -30 degrees Celsius.
“The Russian military’s existing Arctic bases are built Soviet-style and are not really appropriate to live in,” notes the Vladivostok-born Baev
 “Even to reach them during the winter is extremely difficult. Arctic threats to Russia by Nato are negligible; in fact, right now nobody is threatening the troops except Mother Nature.”

That’s the sticking point: there is no real enemy.
As the ice of the Arctic ocean melts, its surrounding countries have a stronger interest in cooperation – or in hydrocarbons and shipping – than in confrontation that will feature sacrifice for uncertain rewards.
And for the time being, the Arctic showdown is mostly a play to the gallery.
“Russia is showing people at home that it’s still a major power, and the Canadian government is playing at threat perceptions to show our power and sovereignty in the Arctic,” says Frédéric Lasserre, a professor at the Université Laval in Quebec who specialises in Arctic geopolitics.
“It’s just a play to get votes.”
