Abstract

On the first several days of October 2013, daily chlorophyll a (chl a) data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the National Aeronautics and Space Administration (NASA) Aqua satellite detected a marked increase in chlorophyll a concentrations (chl a) in the vicinity of Chuuk Lagoon and the Federated States of Micronesia. Such an increase, likely indicative of a phytoplankton bloom, has not been observed in this location at any other time during the MODIS-Aqua mission, which commenced in 2002 and continues to present. Examination of sea surface wind data from the Modern Era Retrospective analysis for Research and Applications Version 2 (MERRA-2) reanalysis dataset indicated that the region experienced a sequence of alternating elevated and very low wind speed events prior to the observation of the bloom. The influence of the winds can be seen in MERRA-2 sea surface skin temperature data. Elevated windspeeds for several days likely induced a mixing of deeper waters with higher nutrient levels to the surface, which was followed by stratification and phytoplankton growth during low wind intervals and finally transport induced by a brief high windspeed event. Analysis of hourly MERRA-2 maximum windspeed data over a 40-year period indicated that this sequence was climatologically rare.

确定2013年10月密克罗尼西亚独特浮游植物爆发的气象和海洋条件
2013年10月的头几天,美国国家航空航天局(NASA) Aqua卫星上搭载的中分辨率成像光谱仪(MODIS)获取的每日叶绿素a (chl a)数据发现,楚克泻湖和密克罗尼西亚联邦附近的叶绿素a浓度(chl a)显著增加。这种增加很可能表明浮游植物大量繁殖,在MODIS-Aqua任务期间的任何其他时间都没有在这个地点观察到。MODIS-Aqua任务从2002年开始,一直持续到现在。对来自现代回顾分析研究与应用版本2 (MERRA-2)再分析数据集的海面风数据的检查表明,在观测到水华之前,该地区经历了一系列交替的高风速和极低风速事件。风的影响可以在MERRA-2海面皮肤温度数据中看到。持续数天的高风速很可能导致较深的水与较高的营养水平混合到水面,随后在低风间隔期间发生分层和浮游植物生长,最后由短暂的高风速事件引起运输。对每小时MERRA-2最大风速40年数据的分析表明,这种序列在气候上是罕见的。
