...and the big dog. Longest / biggest, although lower operational risk (slightly) than the stretch north option.
Bearing in mind that it was also proposing putting an instrumented aircraft pretty close to an international marine boundary, so the political landscape forms part of planning.

That time I asked for aerial imagery supporting an Arctic expedition, timed to coincide with field sampling / drone flights / already planned satellite overpasses. This is one map (of 3), one possible flight path - the "small scenario".
While it had a solid science rationale supported by existing publications - and attracted a lot of big names to the table - the support request was denied.

The place that never freezes: the Arctic habitat where global heating threatens more ice, not less
By Words and pictures by Jimmy Thomson in Nunavut, CanadaThe race to study the North Water between Canada and Greenland before it changes has led to a bold plan for an Inuit-run protected area

Mapping Snow On Northern Winter Roads - A Dual-Frequency Polarimetric Radar Approach For Snow Characterization Over Land, Lake And Sea Ice

“Winter roads are essential transportation links for many remote northern communities, but their safety and reliability depend strongly on snow conditions and ice growth. In this study [link above], [the authors] evaluated a fully polarimetric, dual-frequency Ku- and Ka-band radar approach for retrieving snow depth across landfast sea ice, lake ice, and tundra.
Using field measurements near Churchill, Manitoba, and Resolute Bay, Nunavut [Canada], [they] found that the approach produced snow-depth retrieval bias and error within 3 cm over landfast ice, with encouraging Ku-band performance over frozen ground as well. [They] also developed an interface-detection approach for lake ice that can retrieve both snow depth and ice thickness - a promising direction for characterizing conditions relevant to winter-road planning and safety…”

“Winter roads are lifelines for remote northern communities. Built over land, lakes, rivers, and sea ice, these travel routes are increasingly vulnerable to warming temperatures and variable precipitation. To ensure safety and adapt to these changes, operators require high-resolution monitoring of snow depth across these diverse surfaces, as natural snow accumulation dictates ice growth rates, route viability and road stability. This study extends our polarimetric radar method, previously demonstrated on pack ice, to landfast sea ice, tundra, and frozen lakes and assesses how well we can retrieve snow depth over these surfaces. Results indicate consistency with earlier sea ice analyses, maintaining a mean snow depth retrieval bias and error within 3 cm over the landfast ice. Promising performance is also found over frozen ground using Ku-band (mean biases less than 6 cm). To address the specific challenge of lake ice, which includes strong returns from the ice/water interface, we present a new interface-detection technique that simultaneously retrieves snow depth and ice thickness. While current validation focuses on undisturbed snow, this approach could provide a path forward for characterizing the cryospheric environment in a way that can directly support the optimization of winter roads…”

In July 2026, the #SeaIce global extent was 7.8% below 1991-2020 mean. Since the beginning of records (1978):
- #Arctic, 6th lowest monthly mean, with 9.6% less extent than normal (-878,322 km²)
- #Antarctic, 5th lowest monthly mean, with 6.4% less exent than normal (-1,044,619km²)

Like the majority of our #SeaIce products, the Sea Ice Index is currently based on data from #JAXA 's #AMSR2 sensor. This sensor is being operationally replaced by its successor, #AMSR3, and we are currently adapting our products accordingly.

Work-related: if you are curious about @osi_saf plans to transition their #seaice products from #AMSR2 to #AMSR3 over the summer, please visit https://osi-saf.eumetsat.int
In particular this page:

#SSMIS data-end grows close.
Our #SeaIce team has been busy this summer to ensure product continuity.
Our Sea Ice Index will be updated from v2.2 (SSMIS based) to v2.3 ( #AMSR2 based) from Friday 01/08/2025 on, but access to it will remain unchanged, ensuring a straightforward transition.
More on this: https://osi-saf.eumetsat.int/community/list-of-service-messages/impact-loss-ssmis-data-osi-saf-sea-ice-index

From an original post on BlueSky by William Colgan (@glacierbytes.bsky.social):
“Continued coverage of the plight of US climate science from @science.org here:
The US military has now halted operational data delivery of sea ice extent observations to @nsidc.bsky.social, blinding key eyes on climate change.”

every now and then, I look at this graph, and think about how, for decades, from 1979 until the boreal fall, or austral spring, of 2016, antarctic sea ice just seemed to ignore global warming, showing no trend. Then, suddenly, as the end of 2016 and the southern hemisphere summer approached, *clunk* antarctic sea ice fell down, and did not get up.

It now looks highly likely that the 2024 #Arctic #SeaIce minimum extent will prove to be 4.07 million km² on September 13th, using
#JAXA #AMSR2 data:https://GreatWhiteCon.info/2024/09/facts-about-the-arctic-in-september-2024/#Sep-17
That is 4th lowest for the date, but the equal 5th lowest daily minimum in the satellite era:

It's been a very #icy day, we discussed briefly the new #Antarctic #SeaIce minimum but there is not much to add to this post from @seaice
There really isn't any convincing trend in #AntarcticSeaIce, so we need to be careful with #Attribution

The Alfred Wegener Institute's #AMSR2 based flavour of #Antarctic #SeaIce extent has also posted a new satellite era minimum.

#Arctic #SeaIce extent has been growing fast over the last 3 days, mostly in the Hudson Bay and Chukchi Sea.
Here is an animation of #SeaIce concentration coverage from the Japanese #satellite #AMSR2, processed by yours truly et al 😜.
Have a nice week-end when the time comes!

#Iceberg #A76 calved from the Ronne Ice Shelf in May 2021. It is about 170 km long and 25 km wide and weighs about 1000 Gt.
