Air-Sea Fluxes of Momentum, Heat, and Carbon Dioxide at High Wind Speeds in the Southern Ocean

需要对进入南大洋的大气-海洋二氧化碳通量，特别是在高风速时的大气-海洋通量进行准确的参数化，以便更好地评估全球气候变暖在多风世界的预测如何影响海洋的碳吸收，并改变高纬度地区的海洋热量收支。海气动量、感热和潜热(水蒸气)和二氧化碳(二氧化碳)通量将在巡航中使用适用于船上使用的微气象涡旋相关技术进行连续测量。然后，测量的气体传输速度(K)将与其他已知影响气-海-气通量的参数相关联。这项工作的一个既定目标是收集一套在高风速下直接测量海-气通量的方法，在这种情况下，气体交换与风速的关系的参数设置仍然存在争议。研究将在南大洋的地点进行，使用USAP RV Nathaniel B Palmer作为测量平台。将在总体分析中使用并实现内部一致性检查的共处位置的二氧化碳数据，正在从USAP研究船上的现有正在进行的系统中收集，并获得其他NSF奖项。

Accurate parameterizations of the air-sea fluxes of CO2 into the Southern Ocean, in particular at high wind velocity, are needed to better assess how projections of global climate warming in a windier world could affect the ocean carbon uptake, and alter the ocean heat budget at high latitudes. Air-sea fluxes of momentum, sensible and latent heat (water vapor) and carbon dioxide (CO2) are to be measured continuously underway on cruises using micrometeorological eddy covariance techniques adapted to ship-board use. The measured gas transfer velocity (K) is then to be related to other parameters known to affect air-sea-fluxes. A stated goal of this work is the collection of a set of direct air-sea flux measurements at high wind speeds, conditions where parameterization of the relationship of gas exchange to wind-speed remains contentious. The studies will be carried out at sites in the Southern Ocean using the USAP RV Nathaniel B Palmer as measurment platform. Co-located pCO2 data, to be used in the overall analysis and enabling internal consistency checks, are being collected from existing underway systems aboard the USAP research vessel under other NSF awards.
