This is the beginning of excellent ocean data. I suspect that the
primary driver of the forty year long Arctic warming spell is an
incremental switch up some forty years ago of heat delivered into the
Arctic. This effectively constant heat increment has driven this
whole warming cycle. If it is driven by direct changes in ocean
conditions, then this technology should pick up the signals.
In the meantime we will get real data on the condition of the summer
melt in the Arctic. This is very welcome to myself who has been
tracking conditions from the beginning of this blog. Recall I also
predicted that the sea ice would be in pretty well maximal collapse
by 2012. this has turned out to be essentially correct, and even
stronger that I had actually expected.
The good news is that my lonely prediction that we were facing
eminent collapse to 2012 turned out the be dead on and pretty clearly
proved that the climate scientists involved are uncomfortable with
non linear processes. In fairness NASA came out and said exactly the
same thing shortly after my press release came out. Someone did not
want to look like an idiot and my release gave him the cover to put
his out.
Shipping of some sort is now possible and happening.
However, further ice loss is more difficult and I expect to see
equilibrium established. Sailing across an open polar ocean is
unlikely simply because the Gyre itself will always hold some multi
year ice.
SMOS: the global
success story continues

Paris (ESA) Feb 26, 2013
The Soil Moisture and
Ocean Salinity (SMOS) mission makes global observations of soil
moisture over Earth's landmasses and salinity over the oceans.
Variations in soil moisture and ocean salinity are a consequence of
the continuous exchange of water between the oceans, the atmosphere
and the land - Earth's water cycle.
ESA's water mission is
shedding new light on the meandering Gulf Stream, just one of the
SMOS satellite's numerous achievements. Launched in 2009, ESA's
Soil Moisture and Ocean Salinity satellite has been helping us to
understand the water cycle.
Over the past three
years it has been providing more accurate information on global soil
moisture and ocean salinity.
New results unveiled
in Spain show that SMOS is now providing new insights into the
movement of the Gulf Stream - one of the most intensely studied
current systems.
Originating in the
Caribbean and flowing towards the North Atlantic, the current plays
an important role in the transfer of heat and salt, influencing the
climate of North America's east coast and Europe's west coast.
Salinity
observations from SMOS show that warm, salty water being carried
north by the Gulf Stream meets the colder, less-salty water
transported southward along North America's east coast by the
Labrador Current, mixing the water masses off Cape Hatteras.
SMOS can distinguish
between and follow the resulting eddies that are 'pinched off' from
the current and form little parcels of warm and salty water in the
Labrador Current, and the colder, fresher water in the Gulf Stream.
SMOS is able to
monitor this process thanks to its high resolution and frequent
revisits. This is giving scientists a new view of how salt is
exchanged across current boundaries - a key to understanding the
'conveyor belt' of global oceanic circulation.
These and other
scientific achievements from three years of the SMOS mission were
presented at a conference held at ESA's European Space Astronomy
Centre in Villanueva de la Canada, near Madrid, Spain. SMOS was
realised with special contributions from France and Spain.
"SMOS is the
second Earth Explorer we have placed in orbit - and is delivering
important new information on global soil moisture and ocean salinity
for a broad range of applications," noted Volker Liebig, ESA
Director of Earth Observation Programmes.
The mission's Lead
Investigators, Yann Kerr and Jordi Font, are the focal point of the
scientific research of the mission and lead discussions on soil
moisture and ocean salinity findings.
Unexpected results
demonstrating the versatility of this collaborative European mission
- like the findings on the Gulf Stream - were also highlighted at the
event by Nicolas Reul from Ifremer, France's institute for sea
research.
Surpassing
expectations, SMOS data are being used to monitor Arctic sea-ice
extent and thickness, providing daily coverage of the Arctic Ocean.
In addition, the
satellite can determine wind speeds under hurricanes - such as
last year's Hurricane Sandy that devastated parts of the US east
coast - by measuring the microwave radiation emitted by rough seas.
Today's workshop
included a welcome by the head of ESA's European Space Astronomy
Centre in Spain, Alvaro Gimenez, and a speech on the future of space
technology in Spain by Luis Valero, Spain's General Secretary for
Industry and SMES.
