简介：在从南船座介绍的situ观察，与卫星相结合的漂流检索了SST，雨率被用来通过2012年8月29日从20调查上面的海洋回答到台风Bolaven。在台风Bolaven的经过以后，加深混合的层深度(MLD)，并且冷却混合的层温度(MLT)被观察。在混合的层咸度(MLS)的变化显示出因为在混合的层的导致台风的咸度变化被降水，蒸发，狂暴的混合和thermocline水的upwelling影响，增加并且减少的一个相等的数字。加深MLD并且冷却MLT显示了重要向右偏爱，而MLS被添到台风轨道的左边并且在另外的方面上增加了。铱漂流观察的集中的温度和咸度侧面使在台风的经过以后在上面的海洋看反应过程可能。冷却在近表面并且温暖在表面下被在暴风雨的开发阶段期间定位到气旋的磁道的左边的二铱漂流观察，在远处，最大值的半径相对台风中心弯屈。在混合的层的底和thermocline的顶的水咸度增加是那些二漂流观察的最明显的变化。在轨道并且在台风中心附近的右边上当台风被加强时，从海表面的重要冷却到200的深度

简介：在四国盆的发行量在北方太平洋在副热带的旋回在自台湾东面的菲律宾海流向日本的暖流和水交换的小径起一个很重要的作用。介绍在四国盆部署的漂流的南船座被用来在盆学习发行量和水群众。轨道和从所有Argofloats导出的停车的深度速度领域在四国盆在2000m显示出逆旋风的发行量。在四国盆有inhanced旋涡活动，它在四国盆发行量模式上有大影响。温度的特征-咸度曲线显示有北方PacificOcean热带水(NPTW)，诺思太平洋副热带的模式水(NPSTMW)和在四国盆的北方PacificOcean中间的水(NPIW)。NPTW仅仅是32°N向南存在。盆的Inthe中间的部分，它是28°～31°N，133°～135°E，有一个融合区域。水集中在四国盆与水来自自台湾东面的菲律宾海流向日本的暖流混合。
