The paper presents the results of seven-year survey of Antarctic seals along the western shore of Admiralty Bay, King George Island, South Shetland Islands. Five species were monitored during seven of the eight years, between 1988-95, excluding 1993. Numbers of elephant seals and Antarctic fur seals showed strong annual cycles, fur seals with two seasonal peaks. These of the other three species were more irregular. Fewer Weddell seals were seen in 1994 and 1995 then during the period 1988-92; with this exception, no overall trend in numbers was apparent during the period 1988-95.
Annex VI Regulation for the Prevention of Air Pollutionfrom Ships to the International Convention for the Prevention of Pollution from Ships (MARPOL) provides for establishment of emission control area (ECA), in the areas of emission control of nitrogen oxides (NECA).The new rules apply to the requirement that ships built from 1 January 2016, reduced NOx emission by about 80%. Therefore, considering the early opportunity to take ECA status of the Baltic Sea as an area of NOx control, relevant activities in this field were undertaken by HELCOM. They consist incollecting the documentation and presentation of the International Maritime Organization for approval. According to the HELCOM the Baltic Sea upon entry status of NECA be possible to greatly reduce NOx emission from ships, which will have a positive impact on the marine environment and the health of people living in the Baltic Sea.
