The ocean is broken

IT was the silence that made this voyage different from all of those before it.

Not the absence of sound, exactly.

The wind still whipped the sails and whistled in the rigging. The waves still sloshed against the fibreglass hull.

And there were plenty of other noises: muffled thuds and bumps and scrapes as the boat knocked against pieces of debris.

What was missing was the cries of the seabirds which, on all previous similar voyages, had surrounded the boat.

The birds were missing because the fish were missing.

Exactly 10 years before, when Newcastle yachtsman Ivan Macfadyen had sailed exactly the same course from Melbourne to Osaka, all he’d had to do to catch a fish from the ocean between Brisbane and Japan was throw out a baited line.

“There was not one of the 28 days on that portion of the trip when we didn’t catch a good-sized fish to cook up and eat with some rice,” Macfadyen recalled.

But this time, on that whole long leg of sea journey, the total catch was two.

No fish. No birds. Hardly a sign of life at all.

“In years gone by I’d gotten used to all the birds and their noises,” he said.

“They’d be following the boat, sometimes resting on the mast before taking off again. You’d see flocks of them wheeling over the surface of the sea in the distance, feeding on pilchards.”

But in March and April this year, only silence and desolation surrounded his boat, Funnel Web, as it sped across the surface of a haunted ocean.

North of the equator, up above New Guinea, the ocean-racers saw a big fishing boat working a reef in the distance.

“All day it was there, trawling back and forth. It was a big ship, like a mother-ship,” he said.

And all night it worked too, under bright floodlights. And in the morning Macfadyen was awoken by his crewman calling out, urgently, that the ship had launched a speedboat.

“Obviously I was worried. We were unarmed and pirates are a real worry in those waters. I thought, if these guys had weapons then we were in deep trouble.”

But they weren’t pirates, not in the conventional sense, at least. The speedboat came alongside and the Melanesian men aboard offered gifts of fruit and jars of jam and preserves.

“And they gave us five big sugar-bags full of fish,” he said.

“They were good, big fish, of all kinds. Some were fresh, but others had obviously been in the sun for a while.

“We told them there was no way we could possibly use all those fish. There were just two of us, with no real place to store or keep them. They just shrugged and told us to tip them overboard. That’s what they would have done with them anyway, they said.

“They told us that his was just a small fraction of one day’s by-catch. That they were only interested in tuna and to them, everything else was rubbish. It was all killed, all dumped. They just trawled that reef day and night and stripped it of every living thing.”

Macfadyen felt sick to his heart. That was one fishing boat among countless more working unseen beyond the horizon, many of them doing exactly the same thing.

No wonder the sea was dead. No wonder his baited lines caught nothing. There was nothing to catch.

Tectonic Summary

Seismotectonics of the New Guinea Region and Vicinity

The Australia-Pacific plate boundary is over 4000 km long on the northern margin, from the Sunda (Java) trench in the west to the Solomon Islands in the east. The eastern section is over 2300 km long, extending west from northeast of the Australian continent and the Coral Sea until it intersects the east coast of Papua New Guinea. The boundary is dominated by the general northward subduction of the Australia plate.

Along the South Solomon trench, the Australia plate converges with the Pacific plate at a rate of approximately 95 mm/yr towards the east-northeast. Seismicity along the trench is dominantly related to subduction tectonics and large earthquakes are common: there have been 13 M7.5+ earthquakes recorded since 1900. On April 1, 2007, a M8.1 interplate megathrust earthquake occurred at the western end of the trench, generating a tsunami and killing at least 40 people. This was the third M8.1 megathrust event associated with this subduction zone in the past century; the other two occurred in 1939 and 1977.

Further east at the New Britain trench, the relative motions of several microplates surrounding the Australia-Pacific boundary, including north-south oriented seafloor spreading in the Woodlark Basin south of the Solomon Islands, maintain the general northward subduction of Australia-affiliated lithosphere beneath Pacific-affiliated lithosphere. Most of the large and great earthquakes east of New Guinea are related to this subduction; such earthquakes are particularly concentrated at the cusp of the trench south of New Ireland. 33 M7.5+ earthquakes have been recorded since 1900, including three shallow thrust fault M8.1 events in 1906, 1919, and 2007.

The western end of the Australia-Pacific plate boundary is perhaps the most complex portion of this boundary, extending 2000 km from Indonesia and the Banda Sea to eastern New Guinea. The boundary is dominantly convergent along an arc-continent collision segment spanning the width of New Guinea, but the regions near the edges of the impinging Australia continental margin also include relatively short segments of extensional, strike-slip and convergent deformation. The dominant convergence is accommodated by shortening and uplift across a 250-350 km-wide band of northern New Guinea, as well as by slow southward-verging subduction of the Pacific plate north of New Guinea at the New Guinea trench. Here, the Australia-Pacific plate relative velocity is approximately 110 mm/yr towards the northeast, leading to the 2-8 mm/yr uplift of the New Guinea Highlands.

Cyclones

Tropical cyclone (tc) 14s (irina) has left Madagascar heading towards Swaziland,located approximately 595 nm east-northeast of Maputo, Mozambique. Maputo, known as Lourenço Marques before independence, is the capital and largest city of Mozambique. It is estimated that 80% of the city’s population live in slums without running water or electricity, but the city has little money to invest in infrastructur.
Another Tropical depression (Joni) is formed in the open Sea. It can threaten Rodrigues Islands by next week. Rodrigues Islands is the smallest of the Mascarene Islands and a dependency of Mauritius. Detail update @ Tracking Tropical Storm “IRINA”
