(Table 2) Comparison of water chemistry in 1997 vs. 2003 of lakes in Zackenbergdalen, East Greenland@en

t-tests show that water temperature, total phosphorous and chlorophyll a were significantly higher and that pH and conductivity were significantly lower (two-tailed, p 0.01) in 2003 than in 1997.t检验（t-tests）结果显示，2003年的水温、总磷（total phosphorous）与叶绿素a（chlorophyll a）均显著高于1997年，而pH值与电导率（conductivity）则显著更低（双侧检验，p<0.01）。
