Plate 23 a
Incoming shortwave radiation at the upper ice surface (data from the SHEBA Project
Office installation, right caption) and departure of mast temperature from freezing (average of
clusters1and2at4.2and8.2m,respectively).

Negativetemperature gradient betweenclusters1
and 2, after adjusting temperatures to agree at times near zero heat flux, along with turbulent heat
flux averaged for both clusters (see also in black-and-white on page 148)
