AI Article Synopsis
- The Caribbean region faces challenges in detecting harmful algal blooms due to logistical constraints and limited knowledge.
- The study utilized MODIS Fluorescence Line Height (FLH) data from 2003 to 2013 to identify potential algal bloom areas in the Colombian Caribbean Sea.
- Three key areas with possible persistent blooms were found: Urabá Gulf, Magdalena Rivermouth, and Guajira Peninsula, with nutrient supply during rainy seasons likely contributing to massive algae growth.
Article Abstract
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.
