Elastic Properties of Natural Sea Surface Films Incorporated with Solid Dust Particles: Model Baltic Sea Studies

Table 4

Rheokinetic parameters of dilational surface viscoelasticity obtained in the stress-relaxation experiment performed on solid monoparticulate layers deposited at the sea water interface. A: particles-free surfactant natural film; S: mineral model particle film spread at sea water collected at Jelitkowo (December 11, 2006). Standard deviation is given in brackets.
