Scientific diving (i.e. diving for research purposes organised by universities and research institutes) was excluded from the Act on the performance of underwater works in 2014. With the exception of the introduction of internal regulations at several academic institutions involved in underwater research, to date it remains unregulated at national level. In May this year, an initiative group consisting of six scientific institutions established the Polish Scientific Diving Committee - PKNN. Its aim is to unite Polish institutions using scientific diving in their activities, to represent their interests in the national and international arena, to co-operate and exchange experience, to adopt and develop appropriate standards and procedures, including those relating to safety, and to achieve the future introduction in Poland of regulations fully regulating scientific diving, as well as to support the development of this field of underwater research in Poland.
