A shipping lane through Storfjorden, including a lane along the coast of Edgeøya has been added as a new chart.
New nautical charts, no. 528 (Storfjorden. Sør. Isbukta – Kvalpynten) and no. 532 (Storfjorden. Kvalpynten – Agardhbukta), and a new edition of no. 533 (Storfjorden Nord. Freemansundet – Heleysundet – Sørporten), will be issued on May 9.
The previous edition of chart no. 533 is from now invalid.
Chart no. 528, 532 and 533 are in scale 1:100 000, but chart 533 has two special editions: Ormholet in scale 1:20 000 and Heleysundet 1:50 000.
The width of the chartered corridors are 2,5 nautical miles/5 km.
In addition to the above, the Norwegian Mapping Authorities has also charted a corridor around Sørkapp.
The nautical chart, no. 527, is expected later this summer, AECO said.
These new charts are a result of dialogue and cooperation between AECO, the Norwegian Mapping Authority and the Norwegian Coastal Administration.
AECO invited the mentioned authorities to dialogue meetings with the objective to speed up the charting (and nautical chart production) in cruise industry prioritized areas, including shipping lanes in Storfjorden and around Sørkapp.
What if a country didn't end at the coastline but would simply continue under water?
A territory the size of a continent would come up - a territory uncontrolled and open for seizure. But who owns the sea bed, is it territory still to be claimed?
The fact that the world's oceans cover three-quarters of the earth's surface once meant very little to governments around the world.
This changed when water exploration teamed with demand for specific resources and the need for power.

during the German Atlantic Expedition from 16 April 1925 to 2 June 1927 (from Spieß , 1928).
The first scientific study of the ocean floor was undertaken by German survey vessel Meteor, which saw it conduct research on the Atlantic Ocean between 1925 and 1927.
The information uncovered about the ocean bed changed how nations viewed their once complacent takes on the importance of the ocean - politically and otherwise.
In 1945, spurred on by a demand for oil that could not be met by land resources, US President Harry Truman pioneered the idea of owning oceans by promoting the theory of extended continental shelf of submerged landmass - claiming a continent did not end at the shoreline but ownership by a nation extended into the ocean.
Prior to this, countries could only lay claim to the land extending 22 nautical miles (22km) from land's end.
Arctic Council Search and Rescue Agreement, 2011
Using the theory of 'continental drift' - the belief that the continents' movement in relation to each other did so across ocean beds - and the 'legitimate' nature of science as evidence to prove his point, Truman's idea was systemised under the Outer Continental Shelf Lands Act of 1953, starting a war of laws.
How fair mother nature had been to landlocked nations was another issue to contend with.
"For instance, Russia has a wide [continental] shelf of more than 200 nautical miles, or over 400km. By contrast, South East Africa has a continental edge of only 20km. These features are the result of geological evolution. Some countries are lucky. Others are not," says geophysicist Wilfried Jokat.
Over 40 percent of the world's oceans have already been assigned to legal continental shelves, i.e. a land mass extended from the continent itself to the continental margin which is between the shoreline and the shelf break (where land slopes further into the water).
Claims on expanded geological continental shelves make up another 10 percent of the ocean - a process riddled with loopholes, allowing countries.
It is now projected that around 57 percent of the oceans will eventually be under the control of coastal states.
As new discoveries of oil and gas continue to further nations' desires to claim their own piece of the ocean bed, geologists have been propelled into the role of decision-makers, proving - or nullifying - claims to these desired areas.
The new maritime boundary between Australia and Timor Leste.
The objectivity of the scientists involved in these processes has also come into question, with economic and strategic gains at stake.
"Science is decisive for expanding the continental shelf, because all the petitions are based on science. Geological data, seismic data, scientific studies. Everything depends on this information," says head of the French maritime law commission, Elie Jarmache.
"You can't go to the Commission on the Limits of the Continental Shelf and say, 'I am a member of the Security Council and want to expand my country's continental shelf.' That's not how it works. Politics has no place here."
In 1951, an official map approved by the central government of China marked the China-claimed area in the South China Sea with a pair of non-stopping lines.
There was an inner black line indicating the sovereign boundary and an outer red line representing where China could exercise administrative power.
As states attempt to extend their maritime zones as far as possible, many international conflicts have arisen.
In the South China Sea, eight countries are fighting for oil reserves valued at $100 billion.
"There is no part of the world that is safer than any other," says Robert van de Poll, a maritime law expert. "
In other words, with 53 percent of all maritime boundaries within the Exclusive Economic Zone unresolved, we are seeing conflicts rising to volatile levels driven predominantly by resource development for the offshore."
Researchers often can’t afford to send remotely operated vehicles to the far reaches of the ocean.
Now they’re collaborating with business to take advantage of discoveries made by ROVs deployed by oil and gas companies.

A hammerhead shark skims the ocean floor more than 1,000m (3,400ft) beneath the surface – the deepest observation of the species ever recorded.
These are just two of the remarkable discoveries made by remotely operated vehicles (ROVs) deployed by the Shell Oil Group’s drillship Deepsea Metro 1 in the western Indian Ocean, off the coast of Tanzania.
Images from the ROVs have ended up in peer-reviewed scientific journals in recent years.
Now researchers from Australia, the United Kingdom and the United States, drawing on the knowledge of ROV operators delivered at a workshop last year in Perth, Australia, have outlined scientific research priorities that can be addressed using industry-owned machines, in a new study published in the journal Science of the Total Environment
“The paper was a chance for us as a team to think about what we’d discovered and what we could be discovering in the future,” said Peter Macreadie, associate professor of environmental science at Deakin University in Australia and lead author of the study.
“In the past it’s been ad hoc, but this was about coming together in a more strategic way.”
Oil and gas companies, for instance, fly ROVs up and down the water column as part of their routine environmental compliance requirements, as well as to explore for new resources.
That enables them to see things scientists can only dream of, given the cost of deploying ROVs.
Around 2000, deep-sea biologists and other marine scientists at the National Oceanography Centre (NOC) in the U.K.
were seeking a greater understanding of the biodiversity in the surrounding seas and initiated a consortium with industry.
The initial surveys conducted by the group, said NOC research scientist Daniel Jones, “revealed there were a lot of species that hadn’t been described.” Scientists sought to expand their access to industry ROVs, which was a new technology at the time.
This led to the formation of the Scientific and Environmental ROV Partnership Using Existing Industrial Technology, or SERPENT.

It’s now run out of the NOC with partners at four Australian universities and Louisiana State University.
ROV operators deliver unexpected images of deep-sea life to SERPENT, and scientists visit remote drilling rigs and exploration vessels to conduct experiments.
Industry ROV operators in particular have been enthusiastic about providing scientists with the exceptional photos and video they capture.
“Spending time operating these ROVs out in the ocean, it’s a bit of a lonely existence,” Macreadie said.
“So to have scientists saying, ‘Whoa! What’s that?’ and ‘This is amazing!’ – I think it changes their sense of purpose in their role.”
The oil and gas industry isn’t in the business of making scientific discoveries, of course, but it has a financial incentive to participate in SERPENT and possible future research missions outlined in Macreadie’s paper.
Many oil and gas structures around the world – 4,000 in the Gulf of Mexico alone, according to Macreadie – are due for decommissioning in the next couple of decades.
But ecosystems rich with marine life have grown up around the oil rigs and some conservationists are wondering whether it might be better at this point to leave them in place.
That would save oil companies billions of dollars in removal and remediation costs.
(Some have proposed that a portion of the industry’s savings be devoted to programs to enhance the marine environment.)
The workshop Macreadie’s paper grew out of began as a discussion between scientists and rig operators about this “rigs-to-reefs” concept.
“But the meeting got a little bit hijacked,” he said, by the idea of outlining opportunities for scientific collaboration with industry.
Researchers told the group what they’d like to know about the deep-sea environment.
“Then ROV operators would provide us with a realistic perspective on what could be achievable,” Macreadie said.

The paper described 10 questions that could be answered in part with ROVs.
These include questions about animal behavior in deep-water environments, the distribution and ranges of ocean organisms, the physical and biological processes of the deep ocean, how the ocean is changing, which marine ecosystems are most sensitive to human impact and the degree to which industrial infrastructure such as oil rigs enhance ecosystems.
Most ocean scientists, it’s safe to say, are opposed to new oil and gas development, both due to its climate impact and the potential for environmental disaster, such as the 2010 explosion of the Deepwater Horizon in the Gulf of Mexico.
But that doesn’t mean existing operations shouldn’t be leveraged for scientific discovery, Macreadie said.
“If we had to miss out on that data for the sake of avoiding oil and gas extraction already happening, I think most would sign on to that,” he said.
“But we’re being opportunistic.
It’s happening anyway, so let’s make the most of it.
If they’re doing exploration, we might as well turn it into positive for us.”
On 15 August 2011, an ROV operated by Mako Technologies working for
Hornbeck Offshore Services was conducting seafloor and water column
biotic surveys as part of the Deepwater Horizon oil spill NRDA.
The ROV was being recovered to the vessel when a single Orafish (Regalecus glesne)
was observed at a depth of 62 m.
Nevertheless, challenges remain.
Victoria Todd, managing director of U.K.-based Ocean Science Consulting, which conducts marine mammal surveys and monitoring for industry, has found that, SERPENTnotwithstanding, “it’s really difficult to get the information flowing between academics and industry, and I think that’s where the problem lies.”
Oil and gas representatives in particular “are naturally wary of having their data in the hands of academics” and are “mostly focused on ticking a box for environmental compliance and watching their profit margins,” she said, which makes her skeptical that valuable discoveries made by industry won’t just get “buried.”
But as a reviewer of Macreadie’s paper, she has hope for the future.
“It’s a great paper and maybe there will be the odd person in industry who will read it,” she said.
All but one of the 239 people on the doomed Malaysia Airlines Flight 370 had probably been unconscious — incapacitated by the sudden depressurization of the Boeing 777 — and had no way of knowing they were on an hours-long, meandering path to their deaths.
Along that path, a panel of aviation experts said Sunday, was a brief but telling detour near Penang, Malaysia, the home town of Captain Zaharie Ahmad Shah.
On two occasions, whoever was in control of the plane — and was probably the only one awake — tipped the craft to the left.
The experts believe Zaharie, the plane's pilot, was taking a final look.
That is the chilling theory that the team of analysts assembled by Australia's “60 Minutes” have posited about the final hours of MH370.
They suspect that the plane's 2014 disappearance and apparent crash were a suicide by the 53-year-0ld Zaharie — and a premeditated act of mass murder.
But first, the experts said, they believe that Zaharie depressurized the plane, knocking out anyone aboard who wasn't wearing an oxygen mask.
That would explain the silence from the plane as it veered wildly off course: no mayday from the craft's radio, no final goodbye texts, no attempted emergency calls that failed to connect.
That would also explain how whoever was in control had time to maneuver the plane to its final location.
Video prepared by Ocean Infinity for the commemoration event held in Kuala Lumpur on 3rd March 2018 on the occasion of the fourth anniversary of MH370’s disappearance.
The wreckage has not been found, though hundreds of millions of dollars have gone into the four-year search.
The secret of what happened in the final moments of the ill-fated flight — and the motive behind it all — probably died with its passengers and pilot.
But the “60 Minutes” team — which included aviation specialists, the former Australian Transport Safety Bureau chief in charge of investigating MH370's crash and an oceanographer — put forth what they believe is the most likely theory.
“The thing that gets discussed the most is that at the point where the pilot turned the transponder off, that he depressurized the airplane, which would disable the passengers,” said Larry Vance, a veteran aircraft investigator from Canada.
“He was killing himself. Unfortunately, he was killing everyone else onboard. And he did it deliberately.”
Zaharie's suspected suicide might explain an oddity about the plane's final flight path: that unexpected turn to the left.
“Captain Zaharie dipped his wing to see Penang, his home town,” Simon Hardy, a Boeing 777 senior pilot and instructor, said on “60 Minutes.”
“If you look very carefully, you can see it's actually a turn to the left, and then start a long turn to the right. And then [he does] another left turn. So I spent a long time thinking about what this could be, what technical reason is there for this, and, after two months, three months thinking about this, I finally got the answer: Someone was looking out the window.”
“It might be a long, emotional goodbye,” Hardy added. “Or a short, emotional goodbye to his home town.”
This presentation covers the technical accomplishments undertaken from a geospatial support perspective to support the search for MH370.
Geospatial support embedded within ATSB over the last 3 years included visualization of project data, creation of search areas, data management, statistical analysis and quality review of data collected.
With over 157 TB of data acquired throughout the search the Operational Search for MH370 has become the largest search of survey of its kind ever.
Flight 370 disappeared March 8, 2014, shortly after leaving Kuala Lumpur, bound for Beijing.
The craft is thought to have crashed in the far southern Indian Ocean.
The governments of Malaysia, China and Australia called off the official search in January 2017.
The Australian Transport Safety Bureau's final report said authorities were no closer to knowing the reasons for the plane’s disappearance or the exact location of its wreckage.
But the “60 Minutes” experts tried to answer one of the biggest questions surrounding the flight:
How could a modern aircraft tracked by radar and satellites simply disappear?
Because, they say, Zaharie wanted it to.
And the veteran pilot, who had nearly 20,000 hours of flight experience and had built a flight simulator in his home, knew exactly how to do it.
For example, at one point, he flew near the border of Malaysia and Thailand, crisscrossing into the airspace of both, Hardy said.
But neither country was likely to see the plane as a threat because it was on the edge of their airspace.

But neither country was likely to see the plane as a threat because it was on the edge of their airspace.
Another theory was that he hijacked the plane in protest of the jailing of Anwar Ibrahim, who was then the opposition leader in Malaysia.
A group called the Chinese Martyrs' Brigade claimed responsibility for the downing, although skeptical officials called this a hoax.
Two men on the plane were flying with phony passports, but one was apparently an asylum seeker, and neither had terrorism links.
Current analysis places the most likely site of the MH370 fuselage close to the ‘seventh arc’, which shows possible locations of the plane at the time of the seventh detected radar ping.

The wreckage, of course, might provide some insight about what caused the airplane to crash, and crews were still looking for it as recently as this year.
The latest attempt to discover it was a $70 million effort by a Texas company called Ocean Infinity, according to the Associated Press.
The mission scanned 500 square miles a day during a three-month search.
Ocean Infinity CEO Oliver Plunkett said the company's technology had performed “exceptionally well” and collected “significant amounts of high-quality data.”
Still, it found no trace of MH370.
At 78 feet tall, and churned by a fierce storm, it’s the largest wave ever recorded in the southern hemisphere, New Zealand scientists report.
“This is a very exciting event and to our knowledge it is largest wave ever recorded in the southern hemisphere,” said Tom Durrant, a senior oceanographer with MetOcean Solutions, in a statement. “So, this is a very important storm to capture, and it will add greatly to our understanding of the wave physics under extreme conditions in the Southern Ocean.”
An enormous ocean wave reaching 78.1 feet (23.8 meters) in height has
just hit Campbell Island.
The previous record-breaking wave in this region was recorded in 2012
when a wave was found to have reached 72.3 feet (22.03 meters) in
height in Tasmania.
The intense storm
that has lashed the Southern Ocean around New Zealand and Campbell
Island will soon be giving surfing enthusiasts in California powerful
waves of their own.

The wave was recorded on the night of May 9 by a MetOcean buoy (Campbell island WRB (CIWRB) which is currently floating in the Southern Ocean near Campbell Island about 430 miles (692 km) south of New Zealand.
Campbell Island Wave Rider Buoy was moored on 2 March 2018 at Campbell Island
The wave reached a height of 78 feet (23.8 meters) as a storm rolled through the region.
The previous record, also recorded by MetOcean Solutions, was a 63.6-foot (19.4 meter) wave that rolled through the same patch of ocean last year.

The wave was detected by a single solar powered buoy, which samples wave conditions for 20 minutes every three hours.
The intermittent sampling is done to conserve energy.
During the recording period, the height, period, and direction of each wave is measured, and the data is transmitted to a receiving satellite.
Oceanographers with MetOcean Solutions, a subsidiary of the state-owned Meteorological Service of New Zealand (MetService), believe the peak heights of waves were even higher during the storm. Their wave forecast predicted individual waves reaching heights of 82 feet (25 meters).
The Southern Ocean is one of the least-studied areas on Earth.
Its persistent and energetic winds make it an “engine room” for wave development, producing waves that traverse the globe, including the iconic surfing waves that reach the California coast.
The May 9 storm was generated by the easterly passage of a deep low-pressure system, and accompanied by winds reaching 65 knots (75 mph/120 km/h).
These low-pressure storms are typical in the Southern Ocean, and they can strike at any time of the year, unlike in the northern hemisphere where similar storms only happen in winter.
When measuring waves, oceanographers use a metric called “significant wave height.”
It’s a standard value that characterizes sea conditions, and it takes the average of the highest third of a measured wave.
The May 9 storm produced a significant wave height of 48.9 feet (14.9 meters), which is now a record for the Southern Ocean.
But it’s not the biggest ever recorded; that distinction goes to a 2013 North Atlantic wave with a significant wave height of 62 feet (19 meters).
According to the Smithsonian, the largest wave ever recorded was in Alaska’s Lituya Bay in 1958. It measured 30.5 meters (100 feet) and was caused due to a tsunami, which killed five people. The wave snapped 1,700 trees but did not damage much property as there were a very few towns nearby.
