Abstract

Tin the Cartagena Bay, phytoplanktonic blooms have been documented for more than three decades, as result of the impacts generated by anthropogenic activities. One of these events occurred on August 2019 in a body of water called El Laguito, located in Bocagrande sector. To confirm the event, physical-chemical, biological and optical parameters were evaluated in 12 stations. The Inherent Optical Properties index (POIIndex) identified one station in active bloom, another in increase or decrease bloom conditions and ten in non-bloom condition. The station in active bloom with the highest index value (2.76) reported densities that exceeded 5.80 x 106 cells L−1 of Gymnodinium sp., 41.47 mg/m3 of chla-a, 9.86 pH units and 8.63 mg L−1dissolved oxygen. Therefore, the POI Index constitutes a rapid and low-cost measurement tool for phytoplankton monitoring programs, as well as for monitoring the evolution of phytoplankton blooms.
