The current capacity in the Caribbean region to enhance the knowledge about algal blooms and harmful algal blooms has several logistical constraints. This work aimed to explore the detection of possible algal blooms using Moderate Resolution Imaging Spectroradiometer (MODIS) Fluorescence Line Height (FLH) data in the Colombian Caribbean Sea between 2003 and 2013. Monthly FLH images with 4 km of spatial resolution were processed and classified. The relationship between the Sea Surface Temperature (SST) and the FLH were explored using a Geographically Weighted Regression. The results showed three areas identified as having possible persistent blooms: the Urabá Gulf (UG), Magdalena Rivermouth (MRM), and Guajira Peninsula (GP). The SST does not have any considerable influence on the variation in the FLH. The supply of nutrients during the rainy season may be causing the frequent massive algae growth. MODIS fluorescence was useful as a screening tool to identify risk areas for potential algal blooms.
加勒比地区目前在增强有关藻华和有害藻华知识方面存在若干后勤方面的限制。本项工作旨在探索利用中分辨率成像光谱仪（MODIS）荧光线高度（FLH）数据在 2003 年至 2013 年期间探测哥伦比亚加勒比海可能发生的藻华。对空间分辨率为 4 公里的每月 FLH 图像进行了处理和分类。利用地理加权回归探讨了海面温度（SST）与 FLH 之间的关系。结果显示，有三个地区被确定为可能存在持续性藻华：乌拉巴海湾（UG）、马格达莱纳河口（MRM）和瓜希拉半岛（GP）。SST 对 FLH 的变化没有任何显著影响。雨季期间营养物质的供应可能导致藻类频繁大量生长。MODIS 荧光可作为一种筛选工具，用于识别潜在藻华的风险区域。
