New snowbuoy 2020S99. A touch south east of p207.
"This buoy replaces 2019S92, which was crashed during a ridging event." Does that mean inactive 82, 83, 85, 88-91, 95, 97, 98 met similar fates?
On the inactive snowbuoy setting, they only show 2019S95 which was operative for 6 days at the M7 site co-deployed with 2019O7 and 2019T71:
2019S79 86.00 119.17 07.10.19-28.11.19 (52)
2019S80 85.96 122.71 08.10.19-02.11.19 (26)
2019S92 86.04 117.73 07.10.19-26.11.19 (50)
2019S95 84.62 133.29 11.10.19-17.10.19 (6)
2019S81 88.25 85.17 07.10.19
2019S84 86.49 109.32 07.10.19
2019S86 88.16 69.44 10.10.19
2019S87 88.40 81.98 09.10.19
2019S93 88.04 80.39 07.10.19
2019S94 88.20 74.00 10.10.19
2019S96 88.08 77.50 29.10.19
2020S99 87.96 75.37 10.02.20
"2019S92 was at the
L1 site, co-deployed with 2019R9, 2019W4, 2019I1, 2019F1, 2019T67, one ASFS, one MARC" so we could determine from S92 where the mysterious L1 site is relative to the Polarstern.
Ditto 2019S93 which was co-deployed at
L2 with 2019R8, 2019W2, 2019I2, 2019T63, 2019T65, 2019F2, ASFS, MARC
The ASFS (Shure's sonic atmo sled, see above) that "got eaten by a pressure ridge" was at
L3. They got that unburied on 15 Feb 2020 according to FoMo but it is not yet functioning. At the L1-3 sites, they are trying to do air, ice, ocean in coordination so it hurts to have a major component down.
2019S94 was co-deployed at
L3 with 2019M30, 2019W3, 2019T70, 2019I3, 2019F3, ASFS, UNMANNED-ICE-PRIC
Today at 03:00 the L2 site was at lat lon 88.0420 80.3936 whereas the PS was at 88.1 77.9 per awiMET which is 11.4 km away. The PS can be located slightly better using RAMMB (at 03:27 at 88.074 77.85) which is 10.21 km away but the last known precise location for the PS from S1AB was on 2020 02 02 at 05:46 87.3446 95.4993.
Given a similar calculation for L1 and L3, the three lines could be visualized on GoogEarth where they would not quite radiate out consistently from the PS location because of error but be very close to displaying the overall configuration. Following the L123 triangle over time would show rotation.
Although difficult to see on Sentinel, the KD is still 263 km away from the Polarstern but winds remain moderate (despite the nearby 953 hPa low) and ice pack motion is favorable for trajectory convergence. It's not unusual for ships and explorers get caught on a treadmill where despite a whole day's effort, they make no progress towards their goal. That's not happening here (to the extent the KD can make headway).
