Antarctic Vol. 11 No. 8/12 NZARP Ozone studies mark start of new season Regular flights taking the 200 scientists base and field support staff south for the 1988/89 New Zealand Antarctic Research programme are due to begin in early October. This 48 projects including scientific and survey work will be undertaken mostly in and around Ross Island, McMurdo Sound and the Dry Valleys. Ozone measurements are continuing and have been intensified by scientists who flew south on Winfly. Vegetation studies will be undertaken at Terra Nova Bay to assess environmental impact on which another project involving visits to a number of sites on Ross Island and in McMurdo Sound will also focus. Fish, sponges, Adelie penguins and skuas will also be subject to various studies. Ten divisions of DSIR will be involved in been hampered by cloud.
