How about some _good_ news from #NOAA?
A friend there tells me that all 5 #DeepArgo floats trapped (expectedly) beneath last year's #AntarcticSeaIce and expected to show up this month have done so.
The floats follow a protocol for this. When attempting to surface, if water temperature is too low then back off, descend and collect another profile, try again.
No data is lost but profile locations become harder to pin down. Bathymetry sometimes can help with this; how deep was bottom contact?
"Globally integrated decadal heat content trends of 21.6 (±6.5) TW in the deep and 12.9 (±1.8) TW in the abyssal layer are more certain than previous estimates."
Yes, that's terawatts.
Something's gotta/gonna give.

Deep Argo has gone from zero to Wow! in a very brief time.
"The integrated Steric Sea Level expansion below 2,000 m was 7.9 ± 1 mm compared to the climatology with a trend of 1.3 ± 1.6 mm dec−1 over the Deep Argo era, contributing significantly to the local sea level budget. We assess the ability to close a full Sea Level Budget, further demonstrating the value of a full-depth Argo array."
