  1. Sea ice extent in both the Chukchi and Beaufort seas is at the lowest of the season, though it's still the highest for September 12 since 2018 in NSIDC data. The ongoing stormy weather is likely to increase the open water area at least a bit in the next few days. #akwx #Arctic #SeaIce

  8. "all this ICE got me changing my climate"

    Small seaice bot progress update, mostly done with downloading and ingesting the entire US as vector shapefiles, converting to GeoJSON and a touch more work to index into the db.

    Pumping BigXThe Plug while we crawl up ICE's ass....

  9. Oh baby this is kinda the jackpot, just the missing datasets I need!

    Looking it over this appears to give me damned near enough data to track kidnappings from start to deportation.

    Meanwhile we've got plenty of ground truth data to notice trends, spikes and holes in citizen reporting.

  10. Alright... almost have the website design dialed in.

    Time to switch gears and plumb the backend.

    Thinking of supporting both receiving alerts as a DM if you're an individual. It can also be setup as integration for Mutual Aid groups so if you want to make a ICE specific alert bot for your area you can OR if you have existing accounts you can wire it up to have posts go out from your account.

  11. Apologies, the bots were down for 10 hours. Had a crash I didn't notice, adding more reporting so I get outage alerts.

    Sorry about the downtime.

  12. Alright, finally caught up on sleep.

    How's it been working for people?
    Do you have feature requests?
    Any masto bot best practices?

    I'm gonna analyze how the bots been operating and pace of operations.

    We haven't had an ICE sighting in Seattle proper for an unusually long time so I'm going to work on supporting the areas seeing ICE more than us.

  13. Indeed, I've setup three alert bots so far and have some big updates coming to enable more regions. See more in my devlog thread linked below

    @seaice - Only seattle alerts

    @seaice_usa - Every location there's not a specific bot for

    @seaice_ma - Massachusetts wide alerts

    “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…”

  15. I am on my way to the 13th edition for the Sea Ice Data Assimilation Workshop, hosted by the Danish Meteorological Institute in Copenhagen. This is one of the most important workshop series for our community, always packed with good talks and posters.

    I'll give a presentation tomorrow morning, focusing on the current status and recent upgrades of the @osi_saf #SeaIce #Climate Data Records. Still need to work on my slides 😅 , with me luck.

    Of course, we will also discuss about the future @CopernicusEU satellites #CIMR and #CRISTAL !

  16. “Frozen Waves”

    Photographer Jan Erik Waider is a master of capturing incredible landscape imagery. In these videos, he uses a drone to film waves in the Baltic Sea gently undulating polygonal slabs of ice on the ocean surface. The interplay of light, color, and motion looks almost surreal, but nature is better than we credit at making imagery too good to look away from. (Video and image credit: J. Waider/NorthLandscapes; via Colossal)

  17. #PolarBears in the #BarentsSea are staying fat despite rapid sea #ice loss
    #Arctic #bears may be surviving by shifting to new food sources
    When #seaice goes away, bears get thinner. If bears in a population are losing fat, that can be an early warning population will decline.
    Researchers are interested in polar bears living on #Svalbard because relationship between sea ice and fat loss should be strong. Polar bears there shouldn’t have much fat.

  18. I will not be at #LPS25, Europe's largest 🛰️ Earth Observation conference, in Vienna this week.

    But many of my good friends and colleagues will, including those from @osi_saf , #CCI (Climate Change Initiative), and #CIMR (the future satellite in my profile banner). Catch many of them at the #SeaIce session, but also #SoilMoisture and #SMOS15 sessions.

    Enjoy the conference, while I enjoy some early vacation in Grenoble 😅.

  19. not "what on Earth" but "what in Space!" 😅

    We are developing the prototype ground processor for the #CIMR 🛰️ mission (>= 2029).

    All 20+ Polar Oceans products (including #SeaIce variables) and Global Land products (Soil Moisture, Snow, etc...) for the CIMR mission need documenting. Plus the documents to describe file formats, the software architecture, the future validation campaign 😂 , etc...

    This is our Year 1 review with ESA, so many of the docs are still draft.

    -> github.com/CIMR-L2PAD/

  20. So next week there is a big #SeaIce #DataAssimilation workshop hosted by the European Space Agency in Frascati (Italy).

    I'm one of the organizers, and I'll be there 🙋 with #CIMR 🛰️ and #CCI content. Who will I meet there?

    #IICWGDA12

  21. #ESA, the European #Space Agency, made a cool video about the #CIMR satellite.

    #CIMR is the #Copernicus Imaging Microwave Radiometer. It will fly as one of the future @CopernicusEU #Sentinels from early 2029. It will be a game-changer for observing #SeaIce and the #polar oceans.

    I have been heavily involved in the preparations for this satellite. I'll be happy to answer questions you might have about the video. Just ask them below 👇. #CIMRL2PAD

  22. Polarstern reaches North Pole awi.de/en/about-us/service/pre

    "Five weeks after setting sail from #Tromsø, #Norway, the @awi #ResearchVessel #Polarstern makes a stop at the northernmost point on Earth. Here, too, the international team of #researchers is investigating the coupling between #SeaIce, the #ocean and its life, including within the #DeepSea... the team has discovered an amazing #biodiversity at a previously unmapped #seamount at 1500 meters depth, under the ice."

  23. #ClimateChange: Due to #SeaIce retreat, #zooplankton could remain in the deep longer
    phys.org/news/2023-08-due-sea- #Polarstern #ResearchVessel #ClimateCrisis #Arctic @awi

    Sea-ice decline could keep zooplankton deeper for longer nature.com/articles/s41558-023

    "sunlight is now penetrating deeper and deeper into the #ocean. Since marine zooplankton respond to the available light, this is also changing their behavior—especially how the tiny organisms rise and fall within the water column."

  24. Record low 2022 #Antarctic #seaice led to catastrophic breeding failure of emperor #penguins
    #EmperorPenguin colonies experienced unprecedented breeding failure in a region of Antarctica where there was total sea #ice loss in 2022. The discovery supports predictions that over 90% of emperor penguin colonies will be quasi-#extinct by the end of the century, based on current #globalwarming trends.
