Third time unlucky for Antarctic protection bid


From Nature

The future of the Antarctic — and of the respected international body that governs it — has been jeopardized by another failure to agree on improving environmental protection for the region, scientists warned on Friday 1st.


Help protect Antarctica's great Southern Ocean

For the third time, the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) could not reach agreement on a proposal backed by the European Union, the United States and New Zealand to ban fishing in 1.25 million square kilometres of the Ross Sea.
The plan would establish the world's largest marine reserve, which some researchers say is among the most precious and endangered areas of the polar region.
The Antarctic Ocean Alliance group of non-governmental organizations blamed Russia and Ukraine for blocking the proposals at a meeting in Hobart, Australia, today.
Steve Campbell, the campaign director of the Antarctic Ocean Alliance, said that the result inevitably raised questions about whether CCAMLR could deliver on its commitments to conservation.
Previously, the organization has been well thought of, and is sometimes cited as a good example of how nations can work together to avoid depleting an important common natural resource.
However, the commercial attractiveness of Antarctic fisheries has grown, and a tension between the conservation of this polar wilderness and its exploitation has become increasingly apparent.
“We are worried about CCAMLR’s mandate. We are worried about CCAMLR’s role,” says Campbell.


The Ross Sea, where this killer whale was photographed, is at risk of increased commercial exploitation, but a proposal to place it under protected status has failed to get a 'yes' vote for the third time in a row.

CCAMLR is made up of representatives from 24 countries and the European Union, all of which have to agree if proposals such as the marine reserves are to be accepted.
At last year’s meeting in Hobart, proposals for reserves in the Ross Sea, East Antarctica and the Antarctic Peninsula all failed.
But in an unusual move, another meeting was scheduled in Germany for July this year, raising hopes that at least the Ross Sea proposal would be successful.


However, come July, the Russian delegation became the bête noire of those pushing for the reserves, as agreement on the plans was again not found.
Now, history has repeated itself in Hobart, even though the Ross Sea proposal up for debate this year aimed to protect a smaller area than previous plans.

In a statement distributed by the Australian Science Media Centre, Clive Evans, a researcher at the University of Auckland who has worked on some of the toothfish that live in the Ross Sea, said:
"The failure of CCAMLR to reach consensus on a significantly watered-down proposal from New Zealand and the USA for a marine protected area in the Ross Sea is a victory for political gamesmanship and a slap on the other cheek for [New Zealand], the USA and indeed CCAMLR itself from components of its body corporate.”
Campbell remains positive that the proposals have a fighting chance at next year’s meeting, however, and says that CCAMLR still has an important part to play.
“CCAMLR is a bit of a moon shot — it happens once a year,” he says.
“It was another moon shot this year. Maybe next year we’ll get there.”

Too big to sail? Cruise ships face scrutiny


The Allure of the seas from Royal Caribbean International is the largest cruise ship in the world.

From NYTimes

One of the largest cruise ships in 1985 was the 46,000-ton Carnival Holiday.
Ten years ago, the biggest, the Queen Mary 2, was three times as large.
Today’s record holders are two 225,000-ton ships whose displacement, a measure of a ship’s weight, is about the same as that of a Nimitz-class aircraft carrier.

Cruise ships have grown bigger and bigger in recent years
as cruising has become ever more popular.

Cruise ships keep growing bigger, and more popular.
The Cruise Lines International Association said that last year its North American cruise line members carried about 17 million passengers, up from seven million in 2000.
But the expansion in ship size is worrying safety experts, lawmakers and regulators, who are pushing for more accountability, saying the supersize craze is fraught with potential peril for passengers and crew.
“Cruise ships operate in a void from the standpoint of oversight and enforcement,” said James E. Hall, a safety management consultant and the chairman of the National Transportation Safety Board between 1994 and 2001. “The industry has been very fortunate until now.” 

The perils were most visible last year when the Costa Concordia, owned by the Carnival Corporation, which is based in Miami, capsized off the coast of Italy.
The accident killed 32 people and revealed fatal lapses in safety and emergency procedures. 
 
In February, a fire crippled the Carnival Triumph, stranding thousands without power for four days in the Gulf of Mexico until the ship was towed to shore.
Another blaze forced Royal Caribbean’s Grandeur of the Seas to a port in the Bahamas in May.
Pictures showed the ship’s stern blackened by flames and smoke. 

Although most have not resulted in any casualties, the string of accidents and fires has heightened concerns about the ability of megaships to handle emergencies or large-scale evacuations at sea.
Senator John D. Rockefeller IV, Democrat of West Virginia, introduced legislation this summer that would strengthen federal oversight of cruise lines’ safety procedures and consumer protections.
Cruise operators point out that bigger ships have more fire safety equipment, and contend they are safer.
After a fire aboard the Carnival Splendor three years ago, Carnival adopted new training procedures and added safety features that it says helped with the rapid detection and suppression of the fire on the Triumph.
After the Triumph fire, Carnival also announced it would spend $700 million to improve its safety operations, including $300 million on its fleet of 24 Carnival Cruise Lines ships.

Carnival is the largest cruise operator, owning about half of all cruise ships worldwide.
“We have over time improved the safety of our vessels by better training and better technology and learning from incidents that have happened over the years,” said Mark Jackson, Carnival’s vice president for technical operations, who joined the company in January after 24 years with the Coast Guard. 

Staying the Course: The Challenge of Navigational Demand

Some experts doubt that ships can grow much larger than the current behemoths, marvels of naval engineering that combine the latest technology and entertainment.
Today’s biggest ship, Royal Caribbean’s Allure of the Seas, has 2,706 rooms, 16 decks, 22 restaurants, 20 bars and 10 hot tubs, as well as a shopping mall, a casino, a water park, a half-mile track, a zip line, mini golf and Broadway-style live shows.
It can accommodate nearly 6,300 passengers and 2,394 crew members — the equivalent of a small town towering over the clear blue waters of the Caribbean Sea.
It measures 1,188 feet long. Its sister ship, the Oasis of the Seas, is two inches shorter. 

Experts point out that larger ships have larger challenges.
For instance, they have fewer options in an emergency, said Michael Bruno, dean of the engineering school at the Stevens Institute of Technology in Hoboken, N.J., and former chairman of the National Research Council’s Marine Board.
“Given the size of today’s ships, any problem immediately becomes a very big problem,” he said.
“I sometimes worry about the options that are available.” 

A recent report by the Coast Guard on the Splendor fire revealed glaring problems with the crew’s firefighting abilities as well as failures in fire safety equipment.
The investigation did not address the size of the ship, which carried 3,299 passengers.
But it showed that big vessels can quickly become crippled by small fires that disable complex systems.
No passengers were hurt, but the damage to the engine room was severe, disabling the ship’s power and forcing it to be towed to port in San Diego. 

The investigation found a wide range of problems with the engine’s maintenance history as well as missing fire safety records.
No fire drills had been conducted in the engine room for six months.
Emergency sprinklers were turned off by mistake and then doused the wrong parts of the engine room.
Believing the fire had been contained, the captain vented the engine room to clear out the smoke. He reignited the fire instead. 

These incidents have brought new attention to the behavior of cruise operators.
Rear Adm. Joseph Servidio, the Coast Guard’s assistant commandant for prevention policy, said at a Senate hearing in July that the three fires, including the one aboard the Splendor, “highlight serious questions about the design, maintenance and operation of fire safety equipment on board these vessels, as well as their companies’ safety management cultures.”  

In July, the Coast Guard said cruise ships would need to conduct periodic engine-room fire drills.
The risks of building bigger ships became apparent over a decade ago, as cruise companies pushed the limits of naval architecture.
The head of the International Maritime Organization, the United Nations agency in charge of marine regulations, warned in 2000 of the growing hazards of building larger ships and called for a comprehensive review of safety rules, known as Safety of Life at Sea, or Solas.
William O’Neil, the group’s secretary general at the time, said the industry could not “rely on luck holding indefinitely.”
One result was a set of new global regulations in 2010 called the Safe Return to Port rules.
Those require new ships to have sufficient redundant systems, including power and steerage, to allow them to return to port even in the worst emergency.
Only about 10 ships built since then comply with this new rule. 

“The idea is that a ship is its own best lifeboat,” said John Hicks, the vice president for global passenger ships at Lloyds Register, the largest ship classification society.
“The idea is to do everything to keep the crew and passengers on a vessel.”
Bud Darr, the senior vice president for technical and regulatory affairs at the Cruise Lines International Association, the industry’s trade group, said today’s ships operated under layers of oversight.

 Titanic and modern cruising ship comparison

The Coast Guard inspects each ship that calls at United States ports at least once a year and enforces national and international norms.
Private auditors, hired by cruise operators, perform frequent safety reviews, including comprehensive annual checks that last seven to 10 days, he said, and flag countries like the Bahamas or Panama, where most cruise ships are registered, provide their own oversight.
“We are subject to very close scrutiny,” Mr. Darr said.
“The standards are universal.” 

But incidents like the Costa Concordia grounding have raised questions about whether evacuation regulations are still applicable in the age of megaships.
Under the Solas regulations, for instance, passengers grouped at their muster stations must be able to evacuate on lifeboats within 30 minutes of an evacuation alarm.
The investigation into the Costa Concordia revealed that the crew and its captain failed to sound the general evacuation alarm for more than an hour after rocks had breached the hull.
As a result, some lifeboats could not be lowered once the ship started to list.
After the accident, cruise operators said they would change muster drill procedures.
Instead of holding a drill for passengers within 24 hours of departure, cruise ships said they would do so before ships leave a port. 

While ships are becoming bigger, the burden on crew members is growing.
The Queen Elizabeth 2, which was launched in 1969, had one crew member for about 1.8 passengers. On the Triumph, the ratio was one crew member for every 2.8 passengers. The issue is also complicated by language and communication problems, and a high crew turnover rate that can reach 35 percent a year.
The International Transport Workers’ Federation, which represents seafarers and crew members, has expressed concerns about the evacuation time and suggested the need to limit the number of people aboard ships, depending on where they operate and what search-and-rescue facilities are available.
“Experience has cast doubt on the adequacy of existing lifesaving appliances,” the group said in a report.
“The current equipment, especially lifeboats and life rafts, has proved to be inadequate when confronted with high sea states.” 

Safety rules also state that lifeboats should not carry more than 150 people.

The World's Largest Sister Ships Meet: OASIS and ALLURE together for the first time

But the two largest ships, the Allure of the Seas and the Oasis of the Seas, have much bigger lifeboats, for 370 people, because of a provision of the 2010 rules that allows for exemptions if the cruise line can demonstrate an equivalent level of safety. 

Those bigger lifeboats have only enough room for passengers.
To evacuate the more than 2,300 crew members, the ships are equipped with inflatable rafts that would have to be entered through 59-foot evacuation chutes.
“The simple problem is they are building them too big and putting too many people aboard,” said Capt. William H. Doherty, a former safety manager for Norwegian Cruise Lines, the world’s third-largest cruise operator, and now the director of maritime relations at the Nexus Consulting Group. “My answer is they probably exceeded the point of manageability.”
He added, “The magnitude of the problem is much bigger than the cruise industry wants to acknowledge.”

    Surf spots roar back to life as strong Atlantic swell hits Western Europe : big surf reality check

    The best waves from the mega swell that lit the Atlantic
    in Mullaghmore (Ireland), Belharra (France), Mundaka (Spain) and Nazaré (Portugal). 
    October 26-27-28 2013.

    From SurfMag

    It’s back, like a cold sore. Nazaré Canyon.
    The wave that sometimes isn’t a wave because a wave has a crest and a trough, and Nazaré often lacks the latter.
    The hype that comes with it is back too.
    “Biggest wave ever ridden?”
    “The 100-foot wave?”
    “I’m Ron Burgandy?” 
    Those question marks express doubt, and rightfully so.
    It’s like a surfers version of a cheap philosophical question: If a wave breaks without a bottom, does it break a world record?
    It stirs up a bigger question of how we measure waves, and the inevitable pitfalls flaws we run into in the process.
    A wave is measured as the vertical distance between the crest and the trough.
    Find the bottom.
    Find the top.
    Measure the distance.
    Should be easy.
    But when you’re looking at a wave straight on, especially from elevation, things can get tricky.
    Nazaré Canyon is a caricature of this phenomena .
    At steep waves like Jaws or Maverick’s you can see that the lip is almost directly above the trough (or at least is in the frame).
    But at Nazaré, because the wave is so flat, the distance between the lip and the bottom of the wave might be a 100 feet long, while the wave height is actually more around 60 feet


    Weather forecast 2 days before
    The storm itself was also pretty large, with hurricane-force winds in its center.
    "It developed S/SSW of Greenland on October 25th," explained Surfline's Mike Watson.
    "And this system maintained its intensity as it tracked east the next day, which resulted in a captured fetch -- maximizing swell generation for Europe. A cold front associated with it approached the region early on Monday, which allowed for window of good conditions for spots that prefer south wind."


    100 feet, right?

    See the above example of Carlos Burle’s wave at Nazaré on October 28.
    At first glance it’s the biggest wave ever ridden (or at least as big as either of Garrett’s from the same wave and same camera angle).
    The wave looks 100 feet because we’re seeing about 100 feet of face in the image, but that face isn’t vertical.
    Far from it.
    This is shown in the following graph, which illustrates a virtual cross cut of this wave.

    Graph.

    When looking at waves from the side, like Alain Riou’s wave at Belharra below, you can easily draw a vertical line from the bottom of the wave to meet a horizontal line drawn from the crest of the wave and measure the height that way.
    But that becomes impossible when you’re looking at a wave photographed from the front, because even if you found the bottom of the wave (a subjective location in most photographs), you can’t draw the horizontal line from the crest of the wave toward the bottom because you’d be entering a third dimension that a 2D photograph doesn’t allow.

    Side angle.

    What lessons can we take away?
    1. Nazaré is a place where giant swells are ridden, but these aren’t 100-foot waves. 
    2. The wave is dangerous, as we saw with Maya Gabeira’s broken ankle-to near drowning-combo.
    3. We need a better way to measure waves, especially when they’re photographed from the front. If anyone is knows of any special technology, software or math that is available that might help with something like this, we’d love to hear about it.
