I especially remember my visit to Rotorua back in June 1993, when I was toured around Whaka by Ron Keam and Ted Lloyd -- I can never forget Ted's exclamation of "It's a geyser, and actual geyser!" when we encountered eruptions near Roto-a-Tamaheke. That was evidently a function of increasing water levels there, so I find (as do the authors) the current decrease rather curious.</DIV> <DIV> </DIV> <DIV>All that aside, though, I write because of the time series plots of Figures 2 and 14 in the article. Maybe I missed this answer during my first reading fo the article, but the plots show a very clear annual variation in water levels superimposed on the general increase, the levels generally peaking around January 1 (USA folks remember that's early summer in NZ). Is there a simple explanation for this?</DIV> <DIV> </DIV> <DIV>And "while I've got you here," any geyser news from Orakei Korako, Waiotapu, Waimangu, etc?</DIV> <DIV> </DIV> <DIV>Thanks.</DIV> <DIV> </DIV> <DIV>Scott Bryan</DIV></BODY></HTML>
