In May 2006 I found a system of active subglacial lakes under the West Antarctic ice streams in @NASA_ICE's #ICESat laser altimetry, from my office at @Scripps_Ocean. ICESat showed the ice sheet surface going up and down by up to 10m (30ft) as water moved in and out of the lakes.
What followed was 15 years of $NSF-funded fieldwork in Antarctica to better understand the lakes and their influence on the overlying ice sheet. This involved some tough and long fieldwork, and I am forever grateful to @grumplesiggy for taking this on for @Scripps_Ocean.
One of these $NSF-funded projects was called "WISSARD" -- Whillans Ice Stream Subglacial Access Research Drilling -- and we drilled through ~800m of ice into Whillans Subglacial Lake in January 2013, and collected muddy sediments, water samples and geophysical data.
