Thousands of fishermen empty lake in minutes

Only one day a year the Dogon people of Mali have the right to fish in the sacred waters of Lake Antogo.
Throughout the year, catch a fish here is forbidden, even the food is scarce in this country so dry and hot. However, the ban is lifted once a year, before the rainy season, during a fishing day that the Dogon tribe never would miss it for anything. Indeed, this is a unique opportunity to catch fish.

Hundreds of "fishing" going on the beach and a few hours of prayers.
Thus, nearly 2000 men who rush to the water, basket in hand.
Catching a fish in the lake Antogo stands for luck for the year ahead for the fisherman.
Men also not hesitate to keep fish caught in their mouths so as not releasing them.

Each catches for yourself and then have to hurry because the whole crowd clears the lake from the fish in minutes...until next year !

Arctic passage

From MasterMariner

The maritime industry is preparing for major shifts in navigation, due to the improvements at the Panama Canal.
For a longer view of maritime changes, the world is looking northward as well.

The last thirty years have seen a significant retreat in Arctic sea ice, currently allowing for over a month of navigable water through the Arctic Ocean.
As Arctic ice recedes, countries are looking forward to faster sea routes across the top of the world.
A transit between Vladivostok and Rotterdam, using the northern route, can save approximately 10 days and $300,000 per ship.
Alternately, the voyage is nearly 11,000 nautical miles through the Pacific, Indian, and Atlantic Oceans – including transits through the Suez Canal and the Mediterranean Sea.

The Northern Sea Route

The reductions in ice coverage, seen over longer periods, have resulted in a doubling of vessel traffic in the Arctic since 2005.
Mounting cargo demands, emerging resource development, and the growing popularity of ecotourism add to burgeoning interest in the region.

NOAA is working now, on several fronts, for the new era of Arctic navigation.

U.S. joins Arctic Regional Hydrographic Commission

On October 6, 2010, NOAA led a U.S. delegation that formally established a new Arctic Regional Hydrographic Commission with four other nations.
The commission, which also includes Canada, Denmark, Norway, and the Russian Federation, will promote cooperation in hydrographic surveying and nautical chart making.
The problem is that many Arctic nautical charts are out of date or nonexistent.
Inadequate charts pose a significant risk to marine safety, and could potentially lead to loss of life or environmental disaster.

NOAA issues draft U.S. Arctic Nautical Charting Plan

NOAA’s Office of Coast Survey recently drafted a nautical charting plan devoted exclusively to the U.S. Arctic.
NOAA is sharing the draft plan with other government partners, including the U.S. Navy, National Geospatial Intelligence Agency, and the U.S. Coast Guard, and will solicit comments from both industry and the public. (see testimony of Capt John Lowell, NOAA)
The draft provides detailed plans for additional nautical chart coverage in U.S. Arctic waters and describes the activities necessary to produce and maintain the charts.
The final plan is slated for completion in May 2011.

The Northwest passage

The U.S. Exclusive Economic Zone includes 568,000 square nautical miles of U.S. Arctic waters. About a third of U.S. Arctic waters are navigationally significant.
The majority of charted Arctic waters were surveyed with obsolete technology dating back to the 1800s.
Most of the shoreline along Alaska’s northern and western coasts has not been mapped since 1960, if ever, and confidence in the region’s nautical charts is extremely low.

NOAA surveys high transit areas

Responding to a request from the U.S. Navy, U.S. Coast Guard, Alaska Maritime Pilots, and the commercial shipping industry, NOAA sent one of its premier surveying vessels, NOAA Ship Fairweather, to detect navigational dangers in critical Arctic waters that have not been charted for more than 50 years.

Fairweather, whose homeport is Ketchikan, Alaska, spent July and August 2010 examining seafloor features, measuring ocean depths and supplying data for updating NOAA’s nautical charts spanning 350 square nautical miles in the Bering Straits around Cape Prince of Wales.
The data will also support scientific research on essential fish habitat and will establish new tidal datums in the region.

Coast a 'graveyard' of lost ships

From Delmarva

More than 2,000 Delmarva wrecks featured on new map

For beachcombers, Delmarva's waterways are delivering constant reminders of a bygone era.

The artifacts that have washed ashore from long-forgotten shipwrecks -- everything from button covers to Buddha statues -- hold both historical and mythic value to collectors like Bill Winkler of Ocean View.

"The history is more important than a piece of pottery or glass bottles," he said.

"Literally tons, as in 2,000 pounds per ton plural, have been collected over the past 100 years."

Although not all the items can easily be traced to a particular wreck, given the daunting number of ships lost offshore since the days of the first 17th century settlers, Winkler said they all tell a story.

Now, at least part of the region's sunken history is being told through a map of the Shipwrecks of Delmarva commissioned by National Geographic.

Don Shomette, who's written volumes of literature about nautical history, was tasked with culling the 7,000 known shipwrecks to the 2,200 featured on the map.
Based on predictive modeling, he said between 10,000-12,000 wrecks are believed to lie on or beneath the sea floor.

The region's waterways rival the Outer Banks of North Carolina as the "graveyard of lost ships," he said.
"It was an embarrassment of riches," he said.

"There were so many important sites, and a number of them couldn't be included."

The process of selecting the sites to be included took more than a year itself, Shomette said.
He and cartographer Robert Pratt made the selections based on cultural and historical relevance, as well as diversity. Revolutionary War-era privateers exist alongside 1850s paddle steamers, Navy submarines and modern pleasure cruisers.

"We didn't want to put every work boat and every barge -- even though some of them are enormous in size -- in there," Shomette said.

Assembling the list meant pulling from his life's work: decades spent poring over government documents, letters and old newspapers, determining the location and details of wrecks across the region.

Just like Winkler, Shomette said the importance lies in what the wrecks have to tell him.
"Ships at sea have their own laws, customs and ways separate from land society," he said.
And Shomette said most mariners, whose "roots were at sea," left little or no record in the wider world.

Conversely, he said shipwrecks also serve as time capsules of what society was like at the time they were lost.
"A ship is unique," Shomette said. "A ship is a container of the society that built it, sailed it, fought on it and died in it."

Beth Gott, an interpreter at the Zwaanendael Museum in Lewes, said the site's shipwreck displays -- of the Dutch H.M.S. De Braak, which was captured by the British and capsized off Lewes in 1798, and a wreck discovered during beach replenishment dredging near Roosevelt Inlet in 2004 -- are among the most popular.

"People are fascinated by the story of what happened to it and all the mysteries behind it," she said.

Although an estimated 40,000 artifacts were collected by researchers at the wreck site, Gott said people are still finding items believed to have come from the ship.

"A gentleman just walked in yesterday," she said.
"He found a piece of brown stoneware; he was so excited."

Aside from a few news articles which crop up from time to time, Winkler said most people are unaware of financial and historical wealth beneath the waves.

"The people who know where these shipwrecks are don't really blab about it," he said.
"If I found gold bullion over here, I wouldn't either."

NOAA satellites aid in the rescue of 295 people in 2010

Cospas-Sarsat Programme - The First Generation

From NOAA

In 2010, NOAA satellites were critical in the rescues of 295 people from life-threatening situations throughout the United States and its surrounding waters.
The satellites picked up distress signals from emergency beacons carried by downed pilots, shipwrecked boaters and stranded hikers, and relayed the information about their location to first responders on the ground.


 
NOAA’s polar-orbiting and geostationary satellites, along with Russia’s COSPAS spacecraft, are part of the international Search and Rescue Satellite Aided Tracking system, called COSPAS-SARSAT.
This system uses a network of satellites to quickly detect and locate distress signals from emergency beacons onboard aircraft and boats, and from smaller, handheld personal locator beacons called PLBs.

Alaska had the most people rescued last year with 77, followed by Florida with 37, and West Virginia with 17, who were aboard a downed Army Reserve helicopter.

“With each rescue, the COSPAS-SARSAT system performs the way it was intended — as a real, life-saving network,” said Chris O’Connors, program manager for NOAA SARSAT.

When a NOAA satellite finds the location of a distress signal within the United States or its surrounding waters, the information is relayed to the SARSAT Mission Control Center based at NOAA’s Satellite Operations Facility in Suitland, Md.
From there, the information is quickly sent to a Rescue Coordination Center, operated by either the U.S. Air Force, for land rescues, or the U.S. Coast Guard, for water rescues.

Now in its 29th year, COSPAS-SARSAT has been credited with supporting more than 28,000 rescues worldwide, including more than 6,500 in the United States and its surrounding waters.

2010 SARSAT Rescue Highlights

Of the 295 saves last year, 180 people were rescued from the water, 43 from aviation incidents, and 72 in land situations where they used their PLBs.

• In a joint U.S. Coast Guard-Navy operation, a man was rescued from his capsized boat, 250 miles off of Cape Hatteras, N.C.
• Although not included in the 295 count, Abby Sunderland, a California teen attempting to set a new record for youngest solo sail around the world, was rescued when she activated her emergency beacons. A storm took her mast — which also left her satellite phone inoperable — and left her boat adrift in the southern Indian Ocean over 2,000 miles from shore. Hers is among the non-U.S. rescues in 2010; those numbers will officially be released later this year.

By law, owners of emergency beacons are required to register them with NOAA at: www.beaconregistration.noaa.gov

That registration information often helps provide better or faster assistance to people in distress. It may also provide information about the location of the emergency situation, how many people need assistance, what type of help may be needed and other ways to contact the owner.
