Extension of the HiWASE measurement program at Station Mike.

2006年，英国国家海洋学中心（NOCS）的科学家们在南安普顿安装了额外的传感器来测量大气和海洋交换热量、二氧化碳和动量的速率。这些交换或“通量”的行为是复杂的，并受到许多其他过程的影响。例如，CO2通量可以取决于风速、空气温度和湿度、海水温度、海洋状态、波浪破碎、白顶覆盖、水中的CO2浓度和大气中的CO2浓度。所有这些过程都需要测量，以便了解通量的行为。Polarfront已经配备了船载波浪记录仪（SBWR），可以直接测量波高，但该系统不能测量波浪的方向。作为NOCS项目的一部分，还安装了波浪雷达系统（WAVEX）以提供波浪方向。WAVEX不进行直接的高度测量，但将其方向数据与SBWR的高度数据相结合，可以非常详细地描述海况-Polarfront是世界上唯一一艘同时拥有这两个系统的船舶。NOCS在船舶驾驶台上增加了数字摄像头，以获取白浪率，波浪雷达数据中的海尖峰将用于获得波浪破碎统计数据。这些通量很难直接测量，通常只能在几周的短期航行中由研究船进行测量。迄今为止，对二氧化碳通量的测量很少，在风速超过15米/秒的公海上也没有进行过测量。相比之下，Polarfront上的NOCS系统自2006年9月安装以来一直在持续运行，并且已经测量了超过25米/秒的平均风速。获得高风速数据很重要，因为通量随着风速的增加而迅速增加。Polarfront之所以被选中，是因为它致力于气象观测，不同于世界上任何其他船只。它还占据了一个高风速的位置，因此经常发生大通量。为了了解各种强迫过程之间的相互作用，需要在尽可能广泛的条件下获得大量数据。将测量计划从2年延长到3年（如原计划）将大大增加可用于分析的数据，而项目成本只会增加12%。

In 2006 scientists from the UK's National Oceanography Centre, Southampton (NOCS) installed additional sensors to measure the rate at which the atmosphere and ocean exchange heat, CO2 and momentum. The behaviour of theses exchanges or 'fluxes' is complicated and is affected by many other processes. For example, the CO2 flux may depend on wind speed, air temperature and humidity, sea temperature, sea state, wave breaking, whitecap coverage, CO2 concentration of the water and CO2 concentration in the atmosphere. All these processes need to be measured as well, so that the behaviour of the flux can be understood. The Polarfront was already equipped with a ship borne wave recorder (SBWR) which makes direct measurements of the wave heights, but this system does not measure the direction of the waves. As part of the NOCS project a wave radar system (WAVEX) was also installed to provide wave direction. The WAVEX does not make direct height measurements, but combining its directional data with the height data from the SBWR gives a very detailed description of the sea state - the Polarfront is the only ship in the world to have both systems. NOCS added digital cameras to the ship's bridge to obtain whitecap fraction and sea spikes in the wave radar data will be used to obtained wave breaking statistics. The fluxes are very difficult to measure directly and such measurements are usually only made from research ships, during short cruises of only a few weeks. To date very few measurements have been made of the CO2 flux and none have been made over the open ocean for winds of more than 15 m/s. In contrast, the NOCS systems on the Polarfront have operated continuously since they were installed in September 2006 and measurements in mean wind speeds of more than 25 m/s have already been made. Obtaining high wind speed data is important because the fluxes increase rapidly with increasing wind speed. The Polarfront was chosen for the project since it is dedicated to meteorological observations, unlike any other ship in the world. It also occupies a location where high wind speeds and therefore large fluxes often occur. To understand the interaction between the various forcing process requires a large data set obtained under as wide a range of conditions as possible. Extending the measurement program from 2 years to 3 years (as originally planned) would significantly increase the data available for analysis and would only increase the cost of the project by 12%.
