-Ice mélange dynamics and implications for terminus stability, Jakobshavn Isbræ

The mélange behaves as a weak, granular ice shelf whose rheology varies seasonally. Sea ice growth in winter stiffens the mélange matrix by binding iceberg clasts together, ultimately preventing the calving of full-glacier-thickness icebergs (the dominant style of calving) and enabling a several kilometer terminus advance. Each summer the mélange weakens and the terminus retreats. The mélange remains strong enough, however, to be largely unaffected by ocean currents (except during calving events) and to influence the timing and sequence of calving events. Furthermore, motion of the mélange is highly episodic: between calving events, including the entire winter, it is pushed down fjord by the advancing terminus (at ∼40 m d−1), whereas during calving events it can move in excess of 50 × 103 m d−1 for more than 10 min.
By influencing the timing of calving events, the mélange contributes to the glacier's several kilometer seasonal advance and retreat; the associated geometric changes of the terminus area affect glacier flow. Furthermore, a force balance analysis shows that large-scale calving is only possible from a terminus that is near floatation, especially in the presence of a resistive ice mélange.
The net annual retreat of the glacier is therefore limited by its proximity to floatation, potentially providing a physical mechanism for a previously described near-floatation criterion for calving.

Solar puzzles,

Solar cycle 23,ended in 2008, lasted longer than previous cycles, with a prolonged phase of low activity that scientists had difficulty explaining.

The new NCAR analysis suggests that one reason for the long cycle could be changes in the Sun's conveyor belt. Just as Earth's global ocean circulation transports water and heat around the planet, the Sun has a conveyor belt in which plasma flows along the surface toward the poles, sinks, and returns toward the equator, transporting magnetic flux along the way.

The key for explaining the long duration of cycle 23 with our dynamo model is the observation of an unusually long conveyor belt during this cycle," Dikpati says. "Conveyor belt theory indicates that shorter belts, such as observed in cycle 22, should be more common in the Sun."

Recent measurements gathered and analyzed by Ulrich and colleagues show that in solar cycle 23, the poleward flow extended all the way to the poles, while in previous solar cycles the flow turned back toward the equator at about 60 degrees latitude. Furthermore, as a result of mass conservation, the return flow was slower in cycle 23 than in previous cycles.

In their paper, Dikpati, Gilman, and de Toma used simulations to model how the solar plasma conveyor belt affected the solar cycle. The authors found that the longer conveyor belt and slower return flow could have caused the longer duration of cycle

Sermeq Kujalleq is alive boys

Sermeq Kujalleq-the Greenland glacier believed to have given birth to the iceberg that sank the Titanic nearly a century ago has calved another massive chunk of ice that’s expected to eventually drift south into shipping lanes off Canada’s East Coast.

The Sermeq Kujalleq or Jakobshavn glacier, the second largest in Greenland, has collapsed and shed a 4.35 miles chunk of ice. Jakobshavn drains 7% of Greenland’s Ice Sheet area, and therefore, has the largest drainage basin of all glaciers in Greenland and the Northern Hemisphere.
There has been notably warm weathers in the Ilulissat region this summer and including last winter and my bet is a nice warm winter....

Greece -The Melting Point of Confusion

Another important quantity is the Greek dissipation rate density or Greek dissipation
function, which is only a function of the Spartan fluxes:
D = D(J).
Specific examples will be given below. Note that some Greek und geek authors have different
definitions for the dissipation function, such as T with T the local Greek temperature
field, or T0 with T0 the temperature of the Euro environment or the
temperature the system would acquire if the bank system goes down (down syndrome)it is in thermodynamic equilibrium with
the environment
The
different usages of the word ’Greek dissipation function’ sometimes causes confusion...yep
