A study of the CO emission from dark, quiescent and cold cloudlets (two Bok globules - B157 and L1O14 - and their neighbouring clouds), was carried out through observations of the j=2-1 and J=1-0 transitions of 12C0, 13CO, and C18O at millimeter wavelengths. The observations were made with the POM 1 (beamsize 4.5') and POM 2 (2.5') radio telescopes. The globules B157 and L1O14 are not isolated objects but are clearly linked to bigger clouds, respectively: L1O75 and B362. We find evidence for large variations in the C18O emission. Our study indicates that its abundance relative to 13C0 fluctuates significantly. All the lines have a smooth profile and highly suprathermal widths. We show that a simple clumpy cloud model with clumps overlapping in the position-velocity space, leading to occultation, can match the line profiles in terms of width, peak intensity and smoothness.
