Today, the determination of the dissolved oxygen content of natural waters is practically an essential duty whenever background data is collected for investigations of a hydrobiological, ecological, and nature or environmental protection viewpoint. If the method by which the measurements are carried out is concerned, it can be stated that the 120 year old, classical Winkler-method is inevitable even today. However the development of hydroecological sciences have laid claim to such expectations that the necessity of in situ oxygen determinations have become increasingly important. In our work we present the survival of the traditional Winkler-method in the present practice, we review all those viewpoints which have facilitated the widespread application of in situ oxygen determinations as well as the methods of all the measurements that are presently regularly applied in the investigations of natural waters.
