- SYDNEY -- For the tourists
who made 50,000 dives a year in New Caledonia's crystalline waters, the
Ever Prosperity was simply an intriguing wreck off the exquisite, white-sand
Amedee islet.
-
- The island, a short boat ride from the capital, Noumea,
is the cradle of the local diving industry and a prime tourist destination.
-
- But a fortnight ago the Ever Prosperity's corroding hull
threatened this jewel of the French Pacific territory when it released
an eight-square-mile oil slick just a few hundred metres from Amedee's
beaches. The situation was serious enough for the navy to dispatch a small
flotilla of boats to surround the oil with a 2,000ft barrage and break
up the slick. Through a miraculous combination of weather conditions, it
broke up without seriously affecting the shoreline.
-
- But the incident has concentrated minds on a situation
threatening the entire Pacific. The Ever Prosperity was an ore carrier
which had most of its tanks pumped dry after it sank in 1970, leaving only
a small supply of starter fuel to threaten New Caledonia's reefs. But regional
environment experts say a far greater threat to the region is posed by
the hundreds of wrecks left over from the Second World War, many of which
sank with full tanks and have never been pumped.
-
- 'These things have been corroding for 60 years, as well
as being exposed to catastro phic events like cyclones,' says Sefanaia
Nawadra of the UN's South Pacific regional environment programme. 'It's
a bit like a game of chance: the odds of a leak are stacking up more and
more.'
-
- The problem was brought to the fore in 2000, when residents
of Ulithi atoll in the Federated States of Micronesia (FSM) noticed oil
slicks in their lagoon after a cyclone.
-
- More than 300 gallons a day were pouring from the wreck
of the USS Mississinewa, an oil tanker sunk by a Japanese suicide submarine
in 1944. The remote atoll's 700 residents were unable to swim or fish and
a state of emergency was declared.
-
- Nawadra says there are records of 3,800 wrecks scattered
about the Pacific. Nearly 400 will need further assess ment. Many are icons
of eco-tourism, thanks to the coral that has engulfed them since 1945.
Japanese tourists who dive to explore the wrecks of Chuuk lagoon represent
one of the biggest earners for the FSM's economy.
-
- Draining the oil from the Mississinewa cost $4m, and
many Pacific wrecks would present far greater difficulties. While the Mississinewa
is just 40 metres below the surface, the 550,000 tonnes of war shipwrecks
in the Solomon Islands were sunk in 100-150 metres. 'The costs go up exponentially
the deeper you go,' says Nawadra.
-
- Adding to the problem is that the wrecks remain the property
of the US and Japanese governments and cannot be tampered with by locals
because to do so could desecrate a war grave.
-
- The Mississinewa was not the first wreck to start leaking
oil. Gradvin Aisek, manager of the Blue Lagoon dive shop in the FSM's Chuuk
lagoon, says that the Kiyoshi Maru used to regularly cause minor slicks
in the late 1980s and early 1990s.
-
- His parents remembered the slicks that followed an American
bombing of the Japanese fleet in Chuuk. 'After the bombing, for two, three
or five days the lagoon was totally oily. It took three or four months
to clear all the oil out,' he said.
-
- As with the Mississinewa, funds to clean up the Pacific's
wrecks are unlikely to be made available until a slick occurs. The FSM's
environmental health co-ordinator, Moses Bretrick, says he knows of at
least two shipwrecks which could cause slicks, but doubts that anything
will be done in the short term.
-
- 'That's the concern, that people won't do anything until
oil starts to come out. It may probably be due to the magnitude of the
damage. If the damage is great, we may have urgent people coming to help
contain it, but otherwise it might take time.'
-
- Russell Maharaj, of the South Pacific regional organisation
Sopac, says that the Solomon Islands' problems are particularly acute.
'There are several vessels in that area which actually leak oil,' he said.
'You see slicks when the tide falls and there's not so much rain runoff.
A lot of people have reported it.'
-
- Allan Kemakeza, the Solomons' Prime Minister, agrees:
'We think it will be a disaster very shortly. The Second World War wreckage
in the Solomon Islands is so huge - 200-plus ships were sunk here during
the war. It will be a disastrous issue if the oil leaks.'
