我们估计气体交换率在Kabira礁石垣岛，日本西南部，使用质量平衡计算与双“生物”示踪剂：溶解无机碳（DIC）和溶解氧（DO）。夜间的结果使我们能够获得合理的气体传输velocitykw值，所有这些都超过了风占主导地位的研究。这种差异可能是由于海流和海底地形相互作用产生的湍流的作用。涨潮时的kw与Raymond和科尔（2001）的报告一致，而低潮时的kw明显更高，这似乎是由于与礁底的摩擦增强和/或礁顶处波浪破碎引起的气泡诱导气体转移造成的。
We estimated gas exchange rates in Kabira Reef at Ishigaki Island, southwest Japan, using a mass balance calculation with dual “biological” tracers: dissolved inorganic carbon (DIC) and dissolved oxygen (DO). The nighttime results allowed us to obtain reasonable gas transfer velocitykwvalues, all of which exceeded those obtained in wind-dominant studies. The difference is likely due to the contribution of turbulence generated by the interaction between the current and bottom topography. Thekwobtained during high tides is consistent with that reported by Raymond and Cole (2001), whereaskwduring low tides is significantly higher, which seems to be caused by enhanced friction with the bottom of the reef and/or bubble-induced gas transfer by wave breaking at the reef crest.
