In this study, an integrated approach utilizing satellite technology and field data was employed to monitor Harmful Algal Blooms (HABs) in the Tropical Mexican Pacific (TMP). The 2019 research used the Surface Algal Bloom Index (SABI) algorithm on Modis-Aqua sensor data via Google Earth Engine, pinpointing significant occurrences of HABs in February, August, and October, especially in Banderas Bay, Acapulco Bay, and the Gulf of Tehuantepec. This approach was further enriched by comparative analysis with UAMITPacific microalgae collection samples, incorporating advanced microscopy and molecular phylogenetic techniques for precise taxonomic identification. A notable aspect of this study was the new bloom record of Helicotheca tamesis and Eutreptiella sp., adding to the significance of these observations. The findings provide vital insights for managing HABs and safeguarding marine and coastal resources, emphasizing the importance of focused monitoring during critical months for effective environmental management. This study not only demonstrates the impact of environmental factors such as ocean currents on HAB dynamics but also highlights the effectiveness of integrating various scientific methods. This approach is crucial in offering comprehensive insights into marine ecosystem health and aiding in the protection of crucial marine and coastal environments from the effects of HABs.
