摘要春季和夏季,北冰洋浮冰表面普遍存在融化池塘。关于融化池塘藻类群落的研究还很少。这些研究表明,这些融化池塘是超营养的,对整体生产力的贡献很小。然而,在2014年夏季第六次中国北极之旅北冰洋期间,在加拿大盆地的北极浮冰上观察到了一个封闭的彩色融化池塘,其叶绿素浓度为15.32μg/L。这次水华是由绿藻卡特里亚引起的,其丰度为15.49×10~6个/L,生物量为5.07 mg C/L。随着北极变暖,表层融化池塘内的初级生产力可能需要引起更多的关注。
ABSTRACT Melt ponds are common on the surface of ice floes in the Arctic Ocean during spring and summer. Few studies on melt pond algae communities have been accomplished. These studies have shown that these melt ponds were ultra-oligotrophic, and contribute little to overall productivity. However, during the 6th Chinese Arctic Cruise in the Arctic Ocean in summer 2014, a closed coloured melt pond with a chlorophyll a concentration of 15.32 μg/L was observed on Arctic pack ice in the Canada Basin. The bloom was caused by the chlorophyte Carteria lunzensis at an abundance of 15.49×106 cells/L and biomass of 5.07 mg C/L. Primary production within surface melt ponds may need more attention along with Arctic warming.
