A world built on ice and whales


The International Whaling Commission's (IWC) annual meeting has closed after a tense final day when relations between opposing blocs came close to collapse.
Latin American nations attempted to force a vote on a proposal to create a whale sanctuary in the South Atlantic.
Pro-whaling countries walked out, but eventually it was decided to shelve any vote until next year's meeting.
Environment groups said the delays and wrangling meant important issues for whale conservation were neglected.
But a number of nations pledged new funding for research on small cetaceans, some of which are severely threatened.
Earlier in the meeting, governments agreed new regulations designed to prevent "cash for votes" scandals that have plagued the IWC in the past, and passed a resolution censuring the Sea Shepherd Conservation Society for putting safety at risk during its annual missions to counter Japanese whalers in the Southern Ocean.
But the sanctuary issue threatened to derail the entire session.
"Whale species and populations from the Southern Atlantic oceanic basin were amongst the ones that suffered the most due to commercial whaling on a large scale," Roxana Schteinbarg, from the Argentina-based Institute for the Conservation of Whales, told delegates.

"Fifty-four species live in the waters where the sanctuary is proposed - it is therefore appropriate that the protection of these species in the Southern Ocean Sanctuary be extended and complemented in the reproduction areas in the Atlantic Southern basin."
The 14-strong Buenos Aires bloc of nations knew it did not command the three-quarters majority needed to win, but remained determined to put it to the test.
"We didn't come here to win the sanctuary on the vote, but we wanted to put it to a vote - we believe our conservation agenda cannot be put forward, be stressed, be highlighted, be defended in some issues without a vote," said Brazil's commissioner Marcus Henrique Paranagua.
"Why not vote on things that are controversial?"
Voting with feet
Delegates from pro-whaling countries walked out in protest when a vote was called 
The pro-whaling bloc said this could herald a return to the fractious days of the past, and walked out in an attempt to bring the meeting below the quorum needed for votes to count.
"We fear that the fact of voting will probably damage the very good atmosphere we have established, and might trigger a landslide of many votes for next year which might disrupt the progress we have made," said Japan's alternate (or deputy) commissioner Joji Morishita.
"This was not a hostile move to the Latin American countries - our effort is to try to save this organisation, and it turned out ok."
The good atmosphere, he added, had survived a "very difficult day".
Critics, however, said the pro-whaling countries had tried to hold the commission to ransom by their walkout.
Explosive meeting
The compromise eventually hammered out, after private discussions lasting nearly nine hours, asks countries to strive to reach consensus during the coming year.
The vaquita was among the casualties here 
If that proves impossible, next year's meeting will start with a vote on the South Atlantic Sanctuary.
That could prove a particular concern for the US, which will be aiming at that meeting, in Panama, to secure renewed quotas for its indigenous hunters.
US commissioner Monica Medina agreed the potential vote "put a hand-grenade" under next year's meeting.
"I'm more than a little concerned - we've made good progress on improving the IWC's governance and that's a good thing," she said.
"But as long as we choose to continue fighting, all of the IWC's members will lose; and the world's whales deserve better."
The US played a leading role in the two-year "peace process" that attempted to build a major compromise deal between the various parties, and which collapsed at last year's meeting.
Missing in action
Huge delays during the four days of talks meant that many items on the agenda pertinent to the health of whales and other cetaceans did not get discussed.
Guide to the oceans' great whales
How to prevent whales from being killed by collisions with ships, how to reduce floating debris and how to tackle the growth of noise in the oceans were among the issues that received no discussion.
"Acrimony is often the enemy of conservation - in this case, it meant that a critical meeting on whales failed to address the greatest threats they face," said Wendy Elliott, head of environment group WWF's delegation.
"Several whale and dolphin species are in crisis - teetering on the brink of extinction - and conservation must be front and foremost at next year's IWC meeting, for the sake of the whales and the commission."


The research programmes of the cash-strapped commission received something of a boost with France, Italy and several non-governmental groups pledging a total of about £80,000 ($130,000) for small cetaceans, which include the critically endangered Mexican vaquita.

Gamburtsev 'ghost mountains mystery solved'


Gamburtsev 'ghost mountains mystery solved'
support of seven nations

Scientists say they can now explain the existence of what are perhaps Earth's most extraordinary mountains.
The Gamburtsevs are the size of the European Alps and yet they are totally buried beneath the Antarctic ice.
Their discovery in the 1950s was a major surprise. Most people had assumed the rock bed deep within the continent would be flat and featureless.
Antarctic campSurvey data now suggests the range first formed over a billion years ago, researchers tell the journal Nature.
The Gamburtsevs are important because they are thought to be the location where the ice sheet we know today initiated its march across Antarctica.
Unravelling the mountains' history will therefore inform climate studies, helping scientists to understand not just past changes on Earth but possible future scenarios as well.
"Surveying these mountains was an incredible challenge, but we succeeded and it's produced a fascinating story," Dr Fausto Ferraccioli from the British Antarctic Survey (BAS) told BBC News.
Antartic ice infographic
Dr Ferraccioli was a principal investigator on the AGAP (Antarctica's Gamburtsev Province) project.
This multinational effort in 2008/2009 flew aircraft back and forth across the east of the White Continent, mapping the shape of the hidden mountain system using ice-penetrating radar.
Other instruments recorded the local gravitational and magnetic fields, while seismometers were employed to probe the deep Earth.
The AGAP team believes all this data can now be meshed into a credible narrative for the Gamburtsevs' creation and persistence through geological time.
It is a story that starts just over a billion years ago, long before complex life had formed on the planet, when the then continents were drifting together to create a giant landmass known as Rodinia.
The resulting collision pushed up the mountains, and also produced an underlying thick, dense "root" that sat down in the crust.
Over the course of hundreds of millions of years, the peaks would have gradually eroded away. Only the cold root would have been preserved.
Then, about 250-100 million years ago, when dinosaurs roamed the planet, the crust started to pull apart in a series of rifting events close to the old root.
This rifting warmed and rejuvenated the root, giving it the buoyancy needed to lift the land upwards once more to re-establish the mountains.
Further uplift still was achieved as deep valleys were later cut by rivers and by glaciers.
And it would have been those glaciers that also wrote the final chapter some 35 million years ago, when they spread out and merged to form the East Antarctic Ice Sheet, entombing the Gamburtsevs in the process.
Expanding ice sheetThe Gamburtsevs were a nucleation point for the East Antarctic Ice Sheet
"This research really solves the mystery of how you can have young-looking mountains in the middle of an old continent," said US principal investigator Dr Robin Bell from the Lamont-Doherty Earth Observatory of Columbia University.
"In this case, the original Gamburtsevs probably completely eroded away only to come back, phoenix-like. They've had two lives," she told BBC News.
A proposal is likely to go to funding agencies soon to drill into the mountains to retrieve rock samples. These samples would confirm the model being put forward in the Nature publication.
The search also goes on for a suitable place in the range to drill for ancient ice.
By examining bubbles of air trapped in compacted snow, it is possible for researchers to glean details about past environmental conditions, including temperature of the concentration of gases in the atmosphere such as carbon dioxide.
Somewhere in the Gamburtsev region there ought to be a location where ices can be retrieved that are more than a million years old. This would be at least 200,000 years older than the most ancient Antarctic ice cores currently in the possession of scientists.
To some extent, however, the AGAP survey has actually depressed this quest. The radar data has indicated the base of the sheet has been severely disrupted by water that has been freshly frozen, layer upon layer, on to the bottom of the ice column.

ANTARCTIC GAMBURTSEV PROJECT (AGAP)

Map of Antarctica's Gamburtsev mountains
  • Two camps (N & S) were established deep in the Antarctic interior around the plateau region known as Dome A
  • Aircraft used radar to detect ice thickness and layering, and mapped the shape of the deeply buried bedrock
  • The planes also conducted gravity and magnetic surveys to glean more information about the mountains' structure
  • By listening to seismic waves passing through the range, scientists could probe rock properties deep in the Earth
  • The Gamburtsev range is totally hidden by ice. In some places that ice covering is more than 4,000m thick
  • A key quest was to find a location to drill ancient ice - ice made from snow that has accumulated over a million years
  • The oldest ice drilled so far comes from a location known as Dome C. It records climate conditions 800,000 years into the past

Charity warning over raw sewage discharge levels



Charity warning over raw sewage discharge levels



Discharge from an overflow at Godrevy in CornwallSewage discharges from an overflow on to the beach at Godrevy in Cornwall

Thousands more pipes could discharge raw sewage into the sea, rivers and lakes than was previously thought, the Marine Conservation Society has said.
The conservation charity said the usually published figure of 22,000 discharge pipes in England and Wales should actually be about 31,000.
That is because other categories of pipes have the same function, it said.
The Environment Agency said over £8bn has been invested to upgrade the sewage system over the past 20 years.
The MCS also called for overflow pipes to be mapped and managed more closely.
The charity said that overflow pipes which prevent sewage backing up into drains and houses in times of heavy rain are necessary in an emergency. But water companies needed to invest in the sewer network to ensure untreated waste water was only released in urgent cases.
The MCS also called for overflow pipes to be mapped and managed more closely.
Referring to the 22,000 discharge pipes, the charity said the figure only referred to pipes known as combined sewer overflows and emergency overflows.
'Public information'
The organisation said it had discovered that four other categories of outflows - for example at pumping stations or waterworks - perform the same function, bringing the total figure to an estimated 31,000.
MCS pollution programme manager Dr Robert Keirle said the society "accepts that combined sewer overflows and emergency overflows are an essential part of a well-managed and maintained sewerage network, if sited, used and monitored appropriately.
"However, MCS insists that they should not be used for routine discharge of excess sewage, as an alternative to increasing the capacity of sewers to cope with a growing population."
Dr Keirle also said more needed to be done to map and monitor the outflows, so the public had more information about where they are, if they are monitored and when and for how long sewage is flowing into the sea.
"Mapping costs relatively little yet it could make the difference between an enjoyable trip to the beach or one that ends up in A&E with ear, nose and throat infections or stomach upsets," he added.
Research from the society also suggested there are outlets around the UK coastline which are discharging sewage more than the permitted 10 times a year, including one in Kent which let out waste for more than 1,000 hours during the bathing season in 2010.
A spokesman for the Environment Agency said in addition to the £8bn spent by water companies to upgrade sewer systems and reduce water pollution over the past 20 years, over 98% of beaches had met standards for bathing water quality this year.
He said that the agency had also helped to secure a further £4bn investment by water companies in environmental improvements by 2015.
He added: "The Environment Agency publishes detailed online profiles of every designated bathing water in England and Wales.
"The location of all types of outfall is included in these profiles, along with information on the work being done to improve bathing water quality."

Beach litter levels are too high

Litter is swamping our oceans and is washing up on beaches. It kills wildlife, looks disgusting, is a hazard to our health and costs millions to clear up.
litter on uk beaches - Tim Fanshawe
There are two pieces of litter for every footstep you take on a beach. Marine wildlife gets entangled in litter and accidentally ingests it. Turtles mistake plastic bags for jellyfish and the bags can block their stomachs, often leading to death from starvation.
Seabirds mistake floating plastic litter for food, and over 90% of fulmars found dead around the North Sea have plastic in their stomachs. Plastic litter on beaches has increased 135% since 1994. Plastic never biodegrades. It just breaks down into small pieces but does not disappear.
Microplastic particles are now found inside filter feeding animals and amongst sand grains on our beaches. Litter comes from many sources - the public, fishing activities, sewage pipes and shipping, but it is all preventable.


Beluga body scrub

Beluga whales come together for the annual moult

A film crew has captured the remarkable scene of hundreds of beluga whales indulging in a mass "body scrub" to slough off their skin.
The mammals come en masse into shallow Arctic estuaries where scrubbing their bodies on the stony seabed helps them moult their skin.
"They definitely seem to enjoy it," recalled director Elizabeth White.
Filming for the BBC documentary Frozen Planet, she and her team captured the behaviour up close and from the air.

Ms White was in charge of the ground-based shoot in on Somerset Island in the Canadian Arctic, for which she stood "marooned" on a tower in the middle of the estuary.
This was the best way to get close to the whales, as the tower would be surrounded by water when the tide came in.
"This tower [was used] by the scientists who study the whales here," Ms White explained to BBC Nature.
Natural History Unit crew in the Canadian High Arctic (c) Gretchen FreundThe team filmed close-up footage from a tower in the estuary
"The belugas would swim all the way up to it; they'd even rub themselves against it, which was a bit unnerving."
From this vantage point Ms White and the team captured super slow motion shots of the whales splashing and apparently playing in the water.
They also fixed underwater cameras and microphones to the tower's scaffold, capturing some of the squeaks and cries that have earned belugas the nickname, "canaries of the sea".
The sounds the whales made, Ms White said, was lovely.
Piggybacking babies
Scientists think that the warm, fresh water of the estuary softens the animals' skin.
"You see quite big chunks of blubber around that have just been sloughed off," said Ms White.
To capture aerial shots of hundreds of the white whales in the turquoise water, director Vanessa Berlowitz and cameraman Michael Kelem boarded a helicopter.
"Above marine mammals you can't fly below 300m (1,000ft)," explained Ms White. "But even from this height, [they] managed to get footage of the babies riding on the mothers' back - something that's never been filmed before."
The juvenile whales ride on their mothers' backs occasionally in order to save energy.
Stranded youngster
During their time filming the moult, the crew witnessed one of the hazards the whales encounter when swimming in such shallow water.
"We were there for the lowest tide and one of the youngsters got stranded when we were there," said Ms White.
"The poor little thing got stuck on a sandbank."
Fortunately, she said, this happened late in the day. And with strong sunlight shining on it, and no polar bears around, the young whale was able to escape as soon as the tide came in.
Elizabeth White from the BBC's Natural History Unit describes the team's encounter with a stranded whale.

Labrador Mango rides the waves at Newquay


Newquay dog surfer becomes internet hit


Two-year-old Labrador Mango rides the waves at Newquay with owner Matt Slater
A two-year-old Labrador from Newquay is making waves after being taught to surf by its owner.
The Cornish dog, called Mango, is the star of a new video posted on You tube by its owner Matt Slater.
The video shows him and his children giving Mango lessons on a boogie board in a rockpool on Crantock beach in Newquay.
Mr Slater and his Labrador then head out into the sea to tackle the proper surf.
Mr Slater, who works at the Blue Reef aquarium in Newquay, said: "I've always loved being in and on the sea and have been surfing seriously for 20 years now.
"We first discovered that Mango was up for surfing when she followed my wife and I right out into the surf one day. She is not afraid to swim out back on her own so the next step was to get a bigger board and put her on it."
In the video, available on YouTube, Mr Slater and Mango are seen standing on the same surfboard.
Mr Slater said: "She really seems to enjoy it, and she is absolutely fearless. Plus it's a great way of exercising her as she does end up doing a fair bit of swimming.
"I'd love to get her out on a really nice point break one day. Maybe we will get invited to a dog surf contest in California."
