Abstract

This paper examines the location, intensity, and frequency of zodiac landings by passengers on tourist ships in the Antarctic Peninsula region during 10 seasons, 1989/90 through 1998/99. In this period, the number of passengers increased 307%, from 2460 to 10,013. Zodiac landings have occurred at 165 Peninsula region sites, concentrating in the South Shetland Islands and the northwestern part of the Peninsula. From 1989/90 to 1998/99, the number of zodiac landings in the Peninsula region increased 423%, from 164 to 858. The most visited sites are identified, as are sites experiencing increases in the second half of this 10-year period. The 10 and 20 sites experiencing the most zodiac landings each season consistently account for approximately 55% and 75% of that season's landings, respectively. Based on 1998/99 data, sites with high or medium species diversity or with high or moderate sensitivity to potential environmental disturbance account for a significant percentage of landings. Recommendations are presented for improving the assessment of potential environmental impacts at zodiac landing sites, and for improved methods of reporting site visits by the tour operators involved.
