W okresie lata (sierpień) 1997 roku prowadzono badania albedo powierzchni Lodowca Hansa. Średnie wartości albedo dla promieniowania w zakresie krótkofalowym (300
Results of examination of the influence of the evaporation process on some chosen physical parameters of crude oil extracted from Baltic Sea are given. Variation of mass of the crude oil and of some basic physical magnitudes such as density and viscosity is also presented. The results of measurements show that the largest variation of the examined parameters appear during the first day, mainly in the first six hours from the begining of the experiment. On the subsequent days the values of different parameters are remarkably smaller. The knowledge of the from of the variation is important because fraction which remained after evaportaion can appear in water as volume contaminatin, in diluted form, in form of aggregates, conglomerates, emulsions and sediments.
The work concerns investigation of concentration and particle size distribution mineral suspension in samples of water taken at the Hans Glacier in July of 1996. Particles of suspension were classifield according to their diameter using microscope and then particles size distribution was determined.
