13:40-16:00:  PS149_36-1-snowpit_070

Weather: foggy, sky showing a bit through the fog, calm, warm-ish, slightly frozen SSL. Very cool surface.

snowpit at CORING site (Matthias, Michi, Ruschle)

Measurements:

  •  SnowImager (surface at 3 locations (left, middle, right) and  interface at 1 location (middle, 3x, overlapping by 20 cm), for SSA and density (grid) (interface grid first). SI had a configuration error after the third grid measurement, so there are a few funny measurements around 14:28, where the "bottom image", but not dark image is missing. Matthias brought a new USB drive, and it worked again. Maybe something to do with RD's mac.
  • snow height (every 0.3 m along 4.5 m, left and right of actual snowpit)
  • Density, Salinity, dO18
  • Temperature 
  • Sample for microCT of snow, SSA + interface  (Beautiful sample, according to MJ:)).
  • Salinity and dO18 sample of interface and ice underneath.
  • Photogrammetry for surface roughness of surface


15:45-16:30:   PS149_36-1-snowpit_071

transect at CORING site (Michi, Ruschle)

20 m, every m: SSA (without density grid) starting at 0m, last measurement at 20 m. Density (with grid), offset 0.5 m to right of SSA, between the SSA measurements.

Details:

  • soft bottom at 9m

Photogrammetry for surface roughness at 5,12,20m.

Cool SSL structure at Coring site (070). Last round there was a lot of rain here.
