Dear Geoengineering Group,
For over a year now I have concentrated on occasional information relays to
Climateintervention rather than on the more demanding creative sides, due to my
other climate-related projects. However, I think this observation is important
sea ice aspect to be considered.
I would like to draw an observation and suggest a geoengineering application
from the following statement by NSIDC on 6th Dec 2010:
"As temperatures drop in autumn, open water areas on the Arctic coastal seas
quickly refreeze. After this rapid increase in ice extent during October, ice
growth slows in November. This November, ice extent over the entire Arctic grew
at an average rate of 74,000 square kilometres per day (28,600 miles per day),
which is slower than average. However, local weather conditions kept ice extent
very low in some locations, contributing to the low extent for the month."

Perhaps this overcomes the earlier shortcomings of the suspension cabling
systems blocking the southward movement of sea ice in the Nares Straight
(Ellesemere - Hans Island - Greenland) or on the straights on the Queen
Elizabeth Islands (that bring ice to the NW Passage). Such schemes will fail
the moment the sea ice has started to melt on the north side of the sea ice
blocks. As we saw the sea ice disintegrating and opening seas on the North Pole
in July, August and September we should plan for a total sea ice loss situation.
NSIDC indicates clearly that all multi year ice has gone and now we are down to
thin, if not single season, ice. But either as a fixed or free-floating cables
or platforms could seed ice formation around themselves and stabilise the sea
surface for sea ice growth. Floating platforms and levees would pose least risk
for wildlife, floating mesh wire nets or cables could prove more problematic
for wild life.
Floating net for ship would cause issues, but if we want sea ice on the North
Pole it will have to happen at the expense of some shipping. However, by area
management such a usage issues can, and must be avoided. This is nothing more
than the cloud seeding and rain harvesting to provided surfaces that then start
build up ice around themselves.
If the sea ice could be introduced 4 weeks earlier, say from November to
October in higher seas, this would mean a thicker ice for the spring and more
sunlight reflection for the following season. The sea ice creation will be
enhanced by this.
Also, as a refresher of some earlier discussions in the past, please note that
in the cold and dark autumn conditions (just like in seas around Antarctica),
the breaking-up of sea ice itself tends to seed the rapid ice area growth.
These conditions are much stronger in Antarctica due to the reverse arrangement
of continents to ocean, but can be seen also at times working also in the
Arctic Ocean.
In the warming-up of the spring season, the effect of sea ice break up is the
opposite (as ocean has been mopping up heat). Russian government and the Far
East Shipping Company (FESCO) calls this kind of sea ice manipulation to make
the sea ice melt faster (sea ice demolition) as "ice chipping" and these
operations are carried out at Amurskaya Bay area every year to cut sea ice off
following coastline by driving ice breaker along precise coastal margins in
suitable wind conditions for loosened ice to escape to a warmed-up ocean to
disappear and let the albedo to take over the better weather.
Please give comments, I would like to see our group turning up new ideas like
in the heydays in the past.
Kind regards,
Albert
