Observations on microbial percent respiration values in arctic and subarctic marine waters and sediments

  title={Observations on microbial percent respiration values in arctic and subarctic marine waters and sediments},
  author={Robert P. Griffiths and Bruce A. Caldwell and Richard Y. Morita},
  journal={Microbial Ecology},
Percent respiration was measured in over 1,100 arctic and subarctic marine water and sediment samples using14C-labeled glucose and glutamate. These measurements were made at different times of the year in 4 regions. Percent respiration values were typically lower in regions where the waters of large rivers mixed with seawater. They were also lower in sediments and in waters collected near the bottom than in surface waters. They were higher in winter arctic waters than water samples collected in… CONTINUE READING
