The article presents the legal rules concerning the conduct of marine scientific research in Polish maritime areas by either Polish or the foreign researchers in the light of the international law and the relevant Polish national legislation. According to the 1982 United Nations Convention on the Law of the Sea the foreign researchers have to apply for an express consent of the respective Polish administrative board in order to conduct marine scientific research in Polish marine territory. In Polish exclusive economic zone the consent may be either express or implied. Poland is entitled to withhold, cease or suspend the consent only under certain circumstances determined in accordance with international law. Concerning Polish nationals no consent is required. The compare of Polish national legislation and appropriate regulations of the 1982 United Nations Convention on the Law of the Sea indicates a high degree of compatibility.
The author carried out measurements of radiation in open stations, in narrow spectral ranges of red and far red. He found that the ratio of far red to red is subject to considerable variation with respect to the content of water vapour in the atmosphere (potential precipitation). The author also makes a note of the significance of the changes observed for the phytochromic mechanism, and their probable ecological role in plant life.
