George Osborne orders new icebreaker for UK polar science
http://www.bbc.com/news/science-environment-27129690
The £200m investment in an icebreaker was announced by
Chancellor George Osborne in a speech in Cambridge.
The ship is likely to be 130m long and sport a helipad, cranes,
onboard labs, and have the ability to deploy subs and other ocean survey and
sampling gear.
It should be ready to enter service in 2019, and will support
scientists in both the Antarctic and the Arctic.
The strength of its hull will allow it to push deeper into pack
ice than any previous British research vessel.
Initial technical specifications require the ship to be able to
maintain a speed of three knots while breaking through 2m-thick floes.
The money to build and equip the vessel is coming from the
government's capital investment fund for science, for which Mr Osborne has committed
over £7bn between now and 2020-21.
Addressing an audience at the world-famous Laboratory of
Molecular Biology in Cambridge, the chancellor said science was at the core of
rebalancing the UK economy: "I get that this is something that Britain is
brilliant at, and that it's vitally important to our economic future. So I've
made it my personal priority in government to support [scientists in their]
endeavour."
Mr Osborne added that there would now be a consultation on how
best to spend the £7bn science infrastructure monies.
The UK already operates two polar ships - the Royal Research
Ship (RRS) James Clark Ross and the RRS Ernest Shackleton.
The former was built in 1990 and the latter in 1995.
A case was made to government, and accepted, that this fleet
needed to be augmented with a more modern capability if the nation's science at
high latitudes was to remain competitive.
An early design concept for the new ship has been drawn up by
naval architects, but this will need to be finessed.
A clear imperative is that the final design features a helideck
- something omitted on the Clark Ross and which experts have told the BBC is
really essential for effective Antarctic operations.
Precisely where the ship will be built is an open question.
Given the scale of the investment, a home shipyard would
obviously be preferred. But European Union rules will require that bids also be
invited from beyond the UK.
There is sure to be some concern that the announcement of the
new vessel will signal an imminent reduction in the fleet - one super ship to
replace two ageing vessels.
But the Natural Environment Research Council (Nerc), which funds
polar science in the UK, says this is not the current plan.
The desire is to operate both the Clark Ross and the Shackleton
until at least the end of the decade, it states.
A decision will then be taken on what to do with the Shackleton,
which, unlike the Clark Ross, is not British-owned but leased from a Norwegian
company.
The first of five available one-year extensions to this bareboat
charter arrangement comes into effect in August.
Nerc has made it clear also that the capital investment for the
new ship will not impact the budget for its day-to-day science or ongoing
infrastructure needs. The investment is on a separate government line.
The council has recently upgraded its "bluewater
fleet" - the open-ocean vessels RRS Discovery and RRS James Cook are both
less than 10 years old.
Prof Duncan Wingham, the chief executive of Nerc, told BBC News:
"The new vessel will make Nerc's entire fleet, ton for ton, the most
advanced scientific fleet in the world.
"The new ship will be a clear statement of the UK's
commitment to science in the Antarctic and South Atlantic, and increases our
ice-breaking capability in the south and, just as important, in the
Arctic."
Sir Paul Nurse, the president of the Royal Society, welcomed the
"fantastic" investment in polar science, and said it showed the
chancellor "really does get it".
"Of course, we're still not the biggest spenders on
science; we still look at the US, at Germany and South Korea, who are all
investing more," he added.
"I'm hoping we'll be able to persuade the chancellor, not
only to maintain where he is but also to increase the investment so we can
really compete with those countries."
Comment :
Global warming does not mean an end
to polar ice nor to the need for icebreakers. Even if the Arctic becomes
largely ice-free in summertime later this century, as the latest science
suggests, the legacy of each winter's deep freeze will still litter the ocean -
some of the jagged shards of ice will be visible but many will bob
treacherously just below the surface.
But to understand how the polar
regions are changing, and the implications for everything from wildlife to
fishing to new oilfields to future shipping routes, the view from space offered
by satellites is not enough.
Ice on Artic is very important to balance
and protect artic ecosystem. The polar bear still survive when the ice on the
artic is melt. I think we need to keep virgin the ice on artic. The pollution
and drilling exploration in artic have impact the ice and sea. The drilling
exploration increases global average temperature rise of 2 degrees
