Spatial chlorophyll fluorescence analysis of Banco Chinchorro using terra and aqua MODIS products

Annual average data of four MODIS (Aqua and Terra) products were analyzed, compared and used to explore temporal trends of indicative parameters of net primary productivity and physiological state of phytoplankton in Banco Chinchorro, a coral reef located southeast of the Yucatan Peninsula. The parameters evaluated were: chlorophyll a concentration (Chl a), normalized fluorescence (NFLH), instantaneous photosynthetic active radiation (iPAR) and sea surface temperature (SST4). According with MODIS Aqua, the first results indicate that between 2002 and 2016, there was a small and steady decrease in NFLH (slope m = -0.0008). The temporal trends found were compared against hydro-meteorological events recorded in the region such as tropical storms and hurricanes. Due to lack of information about spatial fluorescence in the study region, the aim of this document is establishes a point of reference for future research, and define a methodology which can be replicated in other regions.
