not a video but a webcam I posted about during the slurry of melt records may have went unnoticed: currently located in beaufort gyre, i guess.

In Science News, another sort of minimum is likely established: So one cannot apply the heat of fusion directly to ultra-small quantities of water.
Toggle Commented Sep 22, 2012 on Minimum open thread at Arctic Sea Ice is far out above Siberia.

Oops, I apparently hit the midnight image, the buoy is still on ice.
Toggle Commented Sep 17, 2012 on Signs of Arctic climate change at Arctic Sea Ice looks like buoy#6 has hit the waterline, or maybe it's been picked up too, does someone know?

That picture looks like Baltic in early march. so I'd say it's about 1 months worth of energy to melt that. I'd say thats about 40 cm of somewhat rotten ice? There's no time this year to do that that far north before sun goes down, so those floes are the future 2nd year ice. (Provided there's not much bottom melt, that is undoubtly different in the Arctic than in the Baltic.)
that was to crandles. thanks,
you're right. checking the antarctic data manually makes for this error that might have spread all over the netizens on various blogs. thank for the correction.
Meanwhile the Antarctic ice area has hit the highest amount since 2007.
Thanks L. Hamilton for the Gompertz values. I guess it's better to have a function around which the measured values dance, rather than guesstimating yearly variations in incoming warmth. At least it (should) make the computations easier. O."does xx extra ppm of CO2 cause ice to lose 0,05cm of it's thickness during a year?" L.
Someone asked recently if James Bay or Hudson could stay ice free in future winters, It looks like the first ice free winter on either would be during an El Nino: As James Bay is on the latitude of north Germany, it's not a question of insolation but the currents and rainfall setting the freezing temperature for the shallow bay. Water there is normally somewhat brackish due the river runoff so the temperature is higher for the ice formation than that in the Arctic Ocean. However the el Nino has been noted to decrease precipitation on the areas draining to Hudson and James, so after a strong el Nino early in the autumn with continued nino phase through winter would be my guess for first ice free Hudson/James. Imho this upcoming event is too late for that.
"quality of the ice" at least 5 types of different ices have their own words in finnish: but they're hard to recognize even when walking on them. 'kohva' traps more air (forms from wet snow) than others (hence it's kinda foggier-grey when even a bit dirty), then there's the capillary action in the nearly invisible cracks on melting ice that some claim makes a different sound when skiing/walking on it than the more solid areas of melting ice. It would be nice to know the weather conditions when the ice formed on a location to be safer, but often this knowledge is not available. Further, the bottom melt on locations may change due the changes in currents so local knowledge of the currents isn't always enough to stay on top of the ice.

Are there any guesses/bets/polls on global ice anomaly? Looks it hit the 8th lowest just yesterday, with some potential to hit the bottom by a wide margin in the coming weeks - 2 months SH sea ice is still likely growing (this year) as the average maximum date is still some 3-4 weeks away, but with an early turnaround down there this graph might need an extension of couple of hundred pixels downwards.
"The regression is impressive - and ugly", apocalypse4real Seconded.
Since here we are mostly discussing arctic processes and their details I'll note here somewhat off topic that El Nino -phase of ENSO has begun (though most probably know it already, This has a lagged influence on atmospheric temperatures (was it by 4 months?), so in October-November-December there should be a rise in global atmospheric temperatures. What does this mean for Arctic isn't too clear as the Arctic is in the dark period and warm air rises. Should the Nino conditions continue until December that is an alltogether different matter.

The current aari drift map shows that the ice on greenland sea would have reversed directions in response to the storm. I haven't checked the Rapid response images though to see how it is shown.

I'd imagine the pressure cannot be used straightforwardly to compare this low to the more southern ones as the Coriolis force should (or shouldn't it) weaken the winds around the center of the low, possibly making high northern lows (or storms) lasting longer than those in NP or NA. Can someone find confirmation of this sort of deduction?

Was just going to suggest summertime Arctic low but I can live with 'arctic summer storm'
The lag in the iniation of photosynthesis and in the decay of living matter during dark times in steadily rising temperatures could possibly produce such a curve. The methane in the bottom could be regarded only as a by-product of this competion, and hence be regarder as a feedback. But anyway, enzyme kinetics is such that one must produce the whole reaction curve experimentally before applying the function to practical designs. And still one may get occasional mutations/invasive species in the fermentation vessel.
