Knut Magne Haugland, LA3KY, of Norway, passed away on December 25. He was 92. Haugland was one of six men, who with Thor Heyerdahl in 1947, successfully crossed the Pacific Ocean in a 45 foot raft made of balsa wood and bamboo -- namedKon-Tiki -- to prove that people from South America could have settled Polynesia in pre-Columbian times.
Called the "most unusual expedition ever to place reliance on Amateur Radio for communication" in the December 1947 issue of QSTKon-Tiki departed Peru for Polynesia on April 28, 1947. "It was the theory of Thor Heyerdahl, Norwegian ethnologist and leader of the venture, that the settlement of the Pacific Islands resulted from a migration of American peoples who had sailed there many of years ago, rather than a trek from Asia as claimed by other scientists," the article explained. "To prove that such a migration was possible, Mr Heyerdahl decided to attempt the trip in a raft of the type preserved in Incan legends and early Spanish historical accounts. He named the expedition on honor of the pre-Incan Sun god. The Kon-Tiki raft was fashioned out of logs of the lightest wood in existence and lashed together with native-made hemp rope. Its only sources of locomotion would be the Pacific trade winds and the Humboldt Current which sweeps northward along the west coast of South America and thence in the direction of the Tuamotu Archipelago."
Haugland and World War II
During World War II, Haugland was a member of the Norwegian Resistance where he was instrumental in the destruction of the Vemork Hydroelectric Plant. When the Nazis took over Norway, they wanted to use the plant -- which produced "heavy water" -- in their quest to produce nuclear weapons. Between 1940 and 1944, a sequence of sabotage actions by the Norwegian resistance movement, as well as Allied bombing, ensured the destruction of the plant and the loss of the heavy water produced. These operations -- codenamed Grouse, Freshman and Gunnerside -- finally managed to knock the plant out of production in early 1943. The Norwegian Resistance Operation Grouse successfully placed four Norwegian nationals -- Haugland, Arne Kjelstrup, Jens-Anton Poulsson and Claus Helberg -- who became Operation Grouse. The four men were parachuted over Hardangervidda on October 18, 1942, to rendezvous with the British Operation Freshman and proceed to Vemork. Once on the ground, the Norwegians began to send back intelligence about the plant, including the composition of its defenses. Operation Freshman failed when the British military gliders crashed short of their destination. All 41 participants were killed in the crash or captured, interrogated and executed by the Nazis. Members of Operation Grouse were then ordered to wait for another team, Operation Gunnerside. In 1943, this team of British-trained Norwegian commandos succeeded at destroying the production facility. In 1965, this feat was made into a movie, The Heroes of Telemark, starring Kirk Douglas;
After the destruction of the plant, Haugland stayed in Hardangervidda for two months and then went to Oslo to train marine telegraphers. After a trip to the United Kingdom for radio supplies, he returned to Norway in November, being parachuted at Skrimfjella. The Nazis arrested him in Kongsberg, but he escaped and commenced his training duties. On April 1, 1944, he narrowly escaped another capture by the Gestapo when one of his transmitters -- hidden in the Oslo Maternity Hospital -- was located by the Nazis using direction finding. Haugland fled to the United Kingdom and did not return to Norway until after the war. For his bravery, Haugland was twice awarded Norway's highest decoration for military gallantry, the War Cross with sword, in 1943 and 1944. In addition, Haugland was awarded the Distinguished Service Order and the Military Medal by the British. He also received the FrenchCroix de guerre and Légion d'honneur and the Royal Norwegian Order of St Olav
Haugland and the Kon-Tiki
Haugland first met Thor Heyerdahl in 1944 at a paramilitary training camp in England. It was here that Haugland first heard of Heyerdahl's theories about Polynesian migration patterns and his plans to cross the Pacific on a balsa wood raft. In 1947, Heyerdahl invited Haugland and Torstein Raaby, another former resistance member, to join the Kon-Tiki expedition as radio operators.
Heyerdahl and his five companions sailed the raft for 101 days more than 4300 miles across the Pacific Ocean before smashing into a reef in the Tuamotu Islands on August 7, 1947. The Kon-Tiki carried 250 liters of water in bamboo tubes. For food, they took 200 coconuts, sweet potatoes, bottle gourds and other assorted fruit and roots. The US Army Quartermaster Corps provided field rations, tinned food and survival equipment. In return, the Kon-Tiki explorers reported on the quality and utility of the provisions. They also caught plentiful numbers of fish, particularly flying fish, mahi-mahi, yellow fin tuna, bonito and shark.
The expedition used call sign LI2B and carried three watertight radio transmitters. The first operated on the 40 and 20 meters, the second on 10 meters and the third on 6 meters. Each unit was made up entirely of 2E30 vacuum tubes providing 10 W of RF input. As an emergency backup, they also carried a German Mark V transceiver originally re-created by Britain's Special Operations Executive in 1942. Other equipment included a hand-cranked emergency set of the Gibson Girl type for use on the maritime bands, a special VHF set for contacting aircraft and two British Mark II transmitters. The Kon-Tiki also carried a National Radio Company NC-173 receiver. Dry batteries and a hand-cranked generator supplied the power.
The December 1947 QST article stated that "the conditions under which the radio equipment aboard the raft was to operate presented many unusual problems. Proximity of the craft's deck to the sea and the relatively small protection afforded by the thatched bamboo cabin meant that the gear would have to withstand the effects of moisture. It was desired to have transmitter units light and tight enough so that if they should fall overboard they could be fished out and put to work again immediately. Operation was required on maritime and amateur frequencies. Both 'phone and c.w. were specified. The transmitters were to be tuned, closed up and remain watertight unless something went wrong. It must be possible to load them up on antennas of whatever length could be erected on available supports. With these requirements in mind, [C. F. Haddock] W1CTW and [H. A. Gardner] W1EHT of the National [Radio] Company's engineering staff designed and constructed the needed rigs. One transmitter was built to operate on 7 and 14 Mc., another for 28 Mc. and a third for 50 Mc."
For the first 22 days following their departure from Peru, the only radio contact Kon-Tiki had was with OBE, the station of the Peruvian Naval School. LI2B kept to its schedule, trying to contact key amateur stations on specified frequencies without success. Finally, on May 20 at 9:44 PST, Harold Kempel, W6EVM, heard and worked LI2B on 14.142 kHz, providing the raft with its first North American contact. By mid-June, LI2B had worked numerous amateur stations.
As the trip progressed, a long-haul network of amateur stations developed. Stations in North America, the Canal Zone and Norway cooperated in handling the Kon-Tiki's traffic. [Gene Melton] W3FNG, in Washington, DC, relayed messages to and from the Norwegian Embassy. "On at least two occasions, urgent traffic was exchanged between the Embassy and the raft via this circuit," the QST article explained. "In one instance, a message was relayed from the raft to W3FNG, delivered by telephone to the Embassy, an answer procured and relayed in the reverse direction to Kon-Tiki -- all in a matter of 35 minutes elapsed time!"
Kon-Tiki's mission ended on August 7, 1947 -- just 101 days after departure from Peru -- when waves deposited the raft on a reef off Raiora Island. "But the safety of the courageous crew which had made the venture a success was still at stake," the QST article said. "Half an hour after being stranded, LI2B was fortunate in making contact with [G. W. Hitch] ZK1AB on Raratonga, who was asked to stand a listening watch and communicate with the Norwegian Embassy in Washington if LI2B was not heard at the end of a 36 hour period. Just before the specified period ended, contact was established with [P. Fuller], W0MNU, and word of the landing passed along, thus avoiding the necessity of sending out any rescue parties."
In his book Kon-Tiki, Heyerdahl described the rush to make contact after landing on the reef, including the crew's despair as the NC-173 slowly dried after getting soaked in a shipwreck, gradually receiving at higher and higher frequencies until eventually settling on the 13.990 MHz frequency needed to make contact:
"Coils and radio parts lay drying in the tropical sun on slabs of coral. The whole day passed, and the atmosphere grew more and more hectic. The rest of us abandoned all other jobs and crowded round the radio in the hope of being able to give assistance. We must be on the air before 10 PM. Then the thirty-six hours' time limit would be up, and the radio amateur on Rarotonga would send out appeals for airplane and relief expeditions.
"Noon came, afternoon came, and the sun set. If only the man on Rarotonga would contain himself! Seven o'clock, eight, nine. The tension was at breaking point. Not a sign of life in the transmitter, but the receiver, an NC-I73, began to liven up somewhere at the bottom of the scale and we heard faint music. But not on the amateur wavelength. It was eating its way up, however; perhaps it was a wet coil which was drying inward from one end. The transmitter was still stone-dead short circuits and sparks everywhere.
"There was less than an hour left. This would never do. The regular transmitter was given up, and a little sabotage transmitter from wartime was tried again. We had tested it several times before in the course of the day, but without result. Now perhaps it had become a little drier. All the batteries were completely ruined, and we got power by cranking a tiny hand generator. It was heavy, and we four who were laymen in radio matters took turns all day long sitting and turning the infernal thing.
"The thirty-six hours would soon be up. I remember someone whispering 'Seven minutes more,' 'Five minutes more,' and then no one would look at his watch again. The transmitter was as dumb as ever, but the receiver was sputtering upward toward the right wavelength. Suddenly it crackled on the Rarotonga man's frequency, and we gathered that he was in full contact with the telegraph station in Tahiti. Soon afterward we picked up the following fragment of a message sent out from Rarotonga: '...no plane this side of Samoa. I am quite sure..."
"Then it died away again. The tension was unbearable. What was brewing out there? Had they already begun to send out plane and rescue expeditions? Now, no doubt, messages concerning us were going over the air in every direction. The two operators worked feverishly. The sweat trickled from their faces as freely as it did from ours who sat turning the handle. Power began slowly to come into the transmitter's aerial, and Torstein pointed ecstatically to an arrow which swung slowly up over a scale when he held the Morse key down. Now it was coming!
"We turned the handle madly while Torstein called Rarotonga. No one heard us. Once more. Now the receiver was working again, but Rarotonga did not hear us. We called Hal and Frank at Los Angeles and the Naval School at Lima, but no one heard us. Then Torstein sent out a CQ message, that is to say, he called all the stations in the world which could hear us on our special amateur wavelength. That was of some use. Now a faint voice out in the ether began to call us slowly. We called again and said that we heard him. Then the slow voice out in the ether said 'My name is Paul. I live in Colorado. What is your name and where do you live?'
"This was a radio amateur. Torstein seized the key, while we turned the handle, and replied, 'This is the Kon-Tiki. We are stranded on a desert island in the Pacific.' Paul did not believe the message. He thought it was a radio amateur in the next street pulling his leg, and he did not come on the air again. We tore our hair in desperation. Here were we, sitting under the palm tops on a starry night on a desert island, and no one even believed what we said.
"Torstein did not give up; he was at the key again sending 'All well, all well, all well' unceasingly. We must at all costs stop all this rescue machinery from starting out across the Pacific. Then we heard, rather faintly, in the receiver, 'If all's well, why worry?' Then all was quiet in the ether. That was all. We could have leaped into the air and shaken down all the coconuts for sheer desperation, and heaven knows what we should have done if both Rarotonga and good old Hal had not suddenly heard us. Hal wept for delight, he said, at hearing LI2B again. All the tension stopped immediately; we were once more alone and undisturbed on our South Sea island and turned in, worn out, on our beds of palm leaves."
After Kon-Tiki
In 1951, Haugland married librarian Ingeborg Prestholdt. He participated in the Independent Norwegian Brigade Group in Germany from 1948-1949, continued in the Forsvarsstaben until 1952, when he was transferred to the Royal Norwegian Air Force. He headed the electronic intelligence service in Northern Norway during the Cold War. He held the ranks of Major from 1954 and Lieutenant Colonel from 1977. In 1963, Haugland left the Air Force to become acting director of the Norway's Resistance Museum; he was later made its permanent director and retired from this position in 1983. He was also the director of the Kon-Tiki Museum from its start in 1947, continuing until 1990.

Can You Learn Anything From a Yacht Race?


Can You Learn Anything From a Yacht Race? | BTalk Australia

Categories: BTalk AustraliaPodcasts


Episode 402; 4 minutes 51) Every year yachting enthusiasts and racing professionals chart the 1,170 kilometre (630 nautical mile) course from Sydney to Hobart, Tasmania.
Success depends in part on the craft and there’s no doubt that engineering and design are providing advances that serious participants needs to embrace if they are to stand any chance in winning.
On the other side there’s determination. It’s no coincidence then that many skippers have a track record in business as well as on the water. Neville Crichton, for example, drove success in the automotive industry in his native New Zealand, then Hawaii, before developing one of the major vehicle import businesses in Australia. He’s the skipper of the Alfa Romeo Maxi yacht.
Earlier this year I spoke to Ed Psaltis. By day a chartered accountant, Ed is the skipper of the AFR Midnight Rambler. The yacht might be a long way down the ranking this year, but in 1998 it was the winner. That was the year that a fierce storm hit the race, with only 44 of the 115 boats making it to Hobart.
So what was it that made Ed and his team so successful that year? Did luck have anything to do with it? As you’ll hear in this episode of BTalk Australia, featuring Ed Psaltis and Paul Kessler (from the Syncretics Group) luck can often be over-rated.
Hear more from Ed and Paul on these previous episodes of BTalk Australia:

INVASIVE SPECIES ARE REAL HAZARDS - ALASKA & GREAT LAKES - WHERE NEXT?










Having just completed the GREAT LOOP route I can tell you first hand that invasive species, i.e. the Asian Carp hazard must be dealt with before it becomes an all out war with many casualties in the food chain - including man. Likewise Alaska should be taking steps to prevent any invasive specie from entering its waters. The Asian Carp has swam up the Mississippi River and invaded the Illinois River and may soon reach the Great Lakes.  What is at risk is a multi-BILLION dollar seafood industry that includes sport fishing should the carp enter the waters of the Great Lake.  The carp eat other species aggressively with no other natural predator keeping the carp over reproduction under control. The battle on the Illinois River which leads into the Great Lakes is being tackled by the Army Corp of Engineers using electrified zones to turn back the Asian Carp. Just recently they have resorted to spraying chemicals into the river. I see this as an outright statement that the electrified zone is not adequate. How effective are these measures?  At what cost to the environment and to man? WHAT ARE THE KNOWN SAFETY ISSUES AND LONG TERM EFFECTS FROM THE CHEMICALS? DO YOU REMEMBER "DDT"? Use Google.com and search using key words "invasive species" "zebra mussel" "asian carp" etc.

Coast Guard Safe Zone To Corral Asian Carp

Updated: Saturday, 19 Dec 2009, 8:58 PM CST

Published : Saturday, 19 Dec 2009, 8:55 PM CST
Fox Chicago News
The United States Coast Guard has instituted a "safety zone" around the Sanitary and Ship Canal's electrified fish net near Romeoville to prevent Aisian Carp eggs from getting into Lake Michigan.
The new regulation prohibits ships from taking on or discharging bilge water in either the Sanitary Ship Canal or Lake Michgan to prevent  Silver Asian Carp eggs from being transmitted to the Lake.  The order was issued by the Coast Guard's Captain in Port Sector Lake Michigan.
State governents around the Great Lakes have asked that the Sanitary Ship Canal locks be sealted to prevent Asian Carp from getting into the lakes where they would likely kill off native species of fish.
A recent fish-kill and search of the ship canal turned up at least one Asian carp, but has not been found in Lake Michigan.

Mich. Takes Invasive Carp Battle to Supreme Court



Michigan has taken its fight against invasive Asian carp to the U.S. Supreme Court, suing Illinois to force the closure of Chicago-area waterways that provide the fish a pathway to the Great Lakes.
Experts fear that the invasive carp, which have been traveling up the Mississippi and Illinois rivers for decades, will devastate the $7 billion Great Lakes fisheries. The 100-pound fish have voracious appetites and rapid reproduction rates that could ravage native lake species.
Michigan's lawsuit asks the high court to immediately close the O'Brien Lock and Dam in the Calumet-Sag Channel and the Chicago Controlling Works in the Illinois River, a stopgap measure aimed at keeping the fish at bay.
But the state also has asked the court to permanently sever the man-made link between the Mississippi River and the Great Lakes, a move long urged by environmental groups and opposed by the shipping industry.
"The actions of Illinois and federal authorities have not been enough to assure us the Lakes are safe," Michigan Attorney General Mike Cox (R) said yesterday in a news release. "That's why the waterways must be shut down until we are assured that Michigan will be protected."
The lawsuit follows tests last month that showed the carp may have crossed an electric fish barrier on the Chicago Sanitary and Ship Canal that is meant to halt their advance, putting them within 6 miles of Lake Michigan.
Earlier this month, officials poisoned a 6-mile stretch of the canal to kill off the carp while the electric barrier was down for routine maintenance. The operation netted one Asian carp, discovered Dec. 3 just above the Lockport Lock and Dam, below the electric barrier.
Michigan's suit attempts to reopen a century-old case spurred when Chicago reversed the flow of the Chicago River to direct its sewage flow toward the Mississippi River.
Noah Hall, a professor at Wayne State University Law School in Detroit, said the court is much more likely to take an existing case than a new one and that Michigan has a strong chance of prevailing if the case does move forward.
"This is not political grandstanding or some kind of publicity stunt," Hall said. "This is a very solid case."
The court likely would weigh the economic consequences for the shipping industry of closing the locks against the economic impacts of allowing the carp to enter the Great Lakes, which are projected to be much larger, Hall said.
The court's ruling on the preliminary injunction, which could come as soon as next week or early January, will hint how it views the larger case, Hall said.

Council wants to zap aquatic tanker stowaways

By WESLEY LOY
Petroleum News
(12/26/09 20:50:01)

An oil industry watchdog group is pushing for construction of a special treatment plant to kill invasive species in ballast water carried aboard oil tankers calling on Valdez to load North Slope crude.
The Prince William Sound Regional Citizens' Advisory Council believes ships could bring in nonindigenous fish, crabs or microorganisms that could take up residence in local waters and potentially harm native aquatic life or commercial and sport fisheries.
The group proposes that a new wing be added to the ballast water treatment plant at the Alyeska dock in Valdez. The main treatment plant would continue its job of cleansing tanker ballast of residual oil before the water is discharged into the Sound, while the new unit would eradicate organisms using ultraviolet or chlorine disinfection and a filtration system.
Ballast water gives tankers that are empty of oil stability as they travel through sometimes heavy seas.
Tankers calling on Valdez can carry two types of ballast, segregated and unsegregated. Segregated ballast is carried in tanks or compartments separate from the cargo holds, while unsegregated ballast is carried in the same holds that also can carry oil.
The volume of unsegregated ballast has dropped sharply in recent years as the tanker fleet has converted from single-hull to double-hull ships, which have segregated ballast tanks.
The fleet upgrade, ironically, has heightened the threat from nonindigenous species, as segregated ballast is simply pumped overboard upon arrival at Valdez, the RCAC says. Aquatic stowaways can't survive the oily unsegregated ballast.
The citizens' advisory council outlined its ideas for an onshore invasive species treatment plant in recent comments to the U.S. Coast Guard, which is proposing nationwide regulations to limit concentrations of living organisms in ballast discharges. The rules potentially could affect the tankers that run between Valdez and West Coast ports.
While onboard eradication systems or ballast exchange are the options getting the most attention, the RCAC argues the fastest and best way to guard against invaders in Prince William Sound is to expand the ballast treatment system at Valdez.
A retrofit of the plant "could be accomplished by 2012," the council told the Coast Guard.
Already, 15 nonindigenous species such as certain algae, sea squirts and shellfish have been identified in the Sound, the council said.
Invaders such as zebra mussels have caused hundreds of millions of dollars in damage in other U.S. waters such as the Great Lakes.
"While there may be other contributors to the nonindigenous species found in Prince William Sound, there is reason to believe that many of these invaders are being transported by crude oil tankers that take ballast water on at West Coast refineries, transport it to Alaska and discharge contaminated ballast into Prince William Sound waters when crude oil is loaded at the Valdez Marine Terminal," the council said.
Anil Mathur, president of Alaska Tanker Co., which carries oil for BP, said his ships already do ballast exchange.
Ballast exchange is when tankers pump out port ballast and take on fresh seawater while sailing north to Valdez. This can flush out living organisms, though it's not a fail-safe measure, the RCAC contends.
Mathur questioned the need for an onshore plant to rid ballast water of potential pests.
He said he's unaware of any "critters from the south" riding in on tankers and taking hold in the cold waters at Valdez. 


Michigan files suit in Supreme Court over Asian carp

By JOHN FLESHER
The Associated Press



TRAVERSE CITY, Mich. — Michigan has asked the U.S. Supreme Court to sever a century-old connection between the Great Lakes and the Mississippi River system to prevent Asian carp from invading the lakes and endangering their $7 billion fishery.

State Attorney General Mike Cox filed a lawsuit with the nation's highest court against Illinois, the U.S. Army Corps of Engineers and the Metropolitan Water Reclamation District of Greater Chicago. They operate canals and other waterways that open into Lake Michigan.
Bighead and silver carp from Asia have been detected in those waterways after migrating north in the Mississippi and Illinois rivers for decades.
Officials poisoned a section of the Chicago Sanitary and Ship Canal this month to prevent the carp from getting closer to Lake Michigan while an electrical barrier was taken down for maintenance.
But scientists say DNA found north of the barrier suggest at least some of the carp have gotten through and may be within 6 miles of Lake Michigan. If so, the only other obstacle between them and the lake are shipping locks and gates, which open frequently to grant passage for cargo vessels.
The lawsuit asks for the locks and waterways to be closed immediately as a stopgap measure, echoing a call by 50 members of Congress and environmental groups last week. But the suit goes further, also requesting a permanent separation between the carp-infested waters and the lakes.
That would mean cutting off a link between the Mississippi and Great Lakes basins created more than 100 years ago, when Chicago reversed the flow of the Chicago River and began sending sewage-fouled Lake Michigan water south toward the Mississippi River.
"The Great Lakes are an irreplaceable resource," Cox, who is seeking the Republican gubernatorial nomination in Michigan, said at a news conference in Detroit. "Thousands of jobs are at stake and we will not get a second chance once the carp enter Lake Michigan."
He likened the notorious fish to "nuclear bombs." The biggest Asian carp can reach 4 feet in length and weigh 100 pounds while consuming up to 40 percent of their body weight daily in plankton, the base of the Great Lakes food chain.
Michigan is seeking to reopen a case dating back to 1900, when Missouri filed suit against Chicago over its re-engineering of the river.
After that issue was resolved, several Great Lakes states — including Michigan — renewed the suit with a new complaint: Chicago's diversion of water away from the basin was harming the lakes by lowering water levels.
The high court has ruled on the matter numerous times, setting ceilings on the amount of Lake Michigan water Chicago could divert. The present limit is 2.1 billion gallons per day.
Michigan's suit argues that continued operation of the locks represents another potential injury to the lakes.
The lawsuit also asks the Supreme Court to require a study of the Chicago waterway system to define where and how many carp are in those waters and to eradicate them.
Noah Hall, an assistant professor at Wayne State University's law school, said Michigan has a good chance of prevailing if it can show the potential harm posed by Asian carp would outweigh the benefits of keeping the locks open.
American Waterway Operators, a trade group of U.S. barges and tugs that haul cargo on the waterways, said closing the locks even temporarily "would be very devastating for our industry ... but also for people in the Chicago region."
But Michigan's lawsuit said losses to barge traffic and recreational boats would be "relatively minor and finite."

Carp and the Lakes

Unwelcome species don’t get much more unwelcome than Asian bighead and silver carp, which were imported to Southern fish farms in the 1970’s, escaped into the Mississippi system and have spent a decade or more moving slowly upriver toward the Great Lakes.
The fish are fertile and voracious, crowding out native species by vacuuming up algae and plankton. They are also bizarrely dangerous to boaters, erupting from the water like self-hurling bricks.
Ever since the fish started heading north, ecologists have warned about the devastation that awaits if they get loose in the Great Lakes, unchecked by natural predators and muscling out every competing species. It is not just the lakes’ $7 billion fishing industry that could be blighted by carp, it’s the entire ecosystem, already badly compromised by other invasive species and pollution.
The watery path that could seal the Great Lakes’ doom is the Chicago Sanitary and Ship Canal, which links the Mississippi River system to the Great Lakes. Electrified underwater barriers erected by the United States Army Corps of Engineers in the canal may already have failed; carp DNA has been detected on the wrong side of the fences.
The federal Environmental Protection Agency is spending a modest $13 million to tighten the canal’s defenses, by shoring up low-lying land beside the canal and nearby carp-infested waterways so the carp can’t ride floodwaters past barricades and into Lake Michigan. In a case that has just reached the United States Supreme Court, Michigan is suing Illinois and the Army Corps to force the closing of two canal locks that give a direct route into the lake.
The only sure way to stop carp — and whatever other invasive species are waiting — is to close the canal and again separate the Mississippi and Great Lakes watersheds. That would be hugely costly and politically difficult, given the importance of shipping to the region.
Closing the canal locks temporarily, while expensive and disruptive, is probably the best way to buy time until a solution can be devised that does not place an immense, fragile ecosystem entirely at the mercy of waterborne shipping. There isn’t a lot of time left to act.
