Brilliant footage of today's @NASA_ICE #ICESat2 launch! Simply incredible to be part of this mission!! Thanks @ulalaunch!!
Launch highlights! ULA's #DeltaII rocket launches @NASA's #ICESat2 mission. The mission marked the final launch of the workhorse rocket, capping 29 years of launching missions for NASA, @usairforce, @NatReconOfc and commercial customers.
The "demand signal" from those living, working, studying and investing in the #Arctic confirmed the requirement for continued monitoring and modeling by @NOAASatellites @NOAAResearch @NASAEarth #NASAEarthAction
Arctic sea ice has a profound influence on the polar environment🧊
September sea ice cover was the 6th lowest in the 45-year satellite record. All 18 of the lowest September sea ice extents have occurred in the last 18 years.

Higher inter-annual variability in key environmental indicators in the #Arctic reveals a very complex, and rapidly changing, region.

Despite the societal and economic importance of the Bering Sea, recent rapid changes in surface ocean conditions are not well documented.
Time to address that gap with some #CryoSat data thanks to @FischerReint @dr_slfarrell & co.

Check out our Multisensor Analyzed Sea Ice Extent - Northern Hemisphere (MASIE-NH) to see data images of where sea ice is today across the Arctic and by region, as well as how the data compare to the last four years. nsidc.org/data/masie

🌊 What else happens when sea ice melts?
In the Bering Sea, declining ice raises ocean energy transfer from winds, increasing wave height and threatening coastal communities, @UofMaryland study finds: go.umd.edu/sea-ice-melting w/ @AOSC_UMD @FischerReint + @dr_slfarrell
Important new research from @essic @UMDResearch @UMDscience published today, led by @AOSC_UMD @FischerReint detailing the recent rapid changes occurring in the #BeringSea where #SeaIce is diminishing and #SignificantWaveHeight is increasing. 🧵 👇
Today, the first paper of my PhD was published in the @ametsoc Journal of Climate: "Understanding Decadal-Scale Dynamics in the Bering Sea: Investigating Trends and Variability in Sea Ice, Winds, and Waves".

Update from the #Arctic: Winter is coming and the days are getting shorter on #Polarstern! However, sometimes we are rewarded with a beautiful sky (if there is no fog...😉). We are now leaving the ice and during our way out we are encountering this peculiar ice type: pancake ice!

Science and poetry collide!
@esa_cryosat's wonderful #ArtistinResidence Peter wraps up the excellent #Cryo2Ice Symposium 2024 with this 👇 🤩👏🎉
Thanks everyone for a great few days in #Iceland
We're enjoying Golden times for polar satellite altimetry thanks to @esa_cryosat @NASA_ICE #Cryo2Ice and @NASAGoddard's Aimée Gibbons notes the data are critical. Not only for doing fundamental research but also for addressing climate and societal challenges.

Wonderful to see #UMD rise to No. 12 among public institutions in @Forbes 2024 rankings of America’s Top Colleges. We were also named the No. 34 research university and No. 41 college in the country. go.umd.edu/1ri6
Wow!
Hurricane #Helene 🌀 has made landfall in #Florida 🇺🇸 as a Category 4 storm with winds of 225 km/h, according to @NHC_Atlantic
🔽The path of #Helene and #HurricaneJohn visualised in the #CopernicusMarine #MyOceanViewer

And the future, you ask? What's up next for #PolarAltimetry? It's exciting! We're busy planning for the upcoming @esa #CRISTAL mission, due for launch in 2027/2028. #Cryo2Ice Symposium 2024.
Emphasizing the importance of role models in #STEM science we're dedicating a #Cryo2Ice Symposium 2024 session to discuss @WomenInScience in #PolarSatelliteAltimetry and tackling the grand challenges in polar climate.
