process generated by photoautotrophic organisms that transform inorganic carbon
into organic macronutrients and micronutrients via photosynthesis. While in
situ studies have shed light onto the spatial and seasonal variations of
chlorophyll a (Chl a) concentration, and thus PP, in speci!c study sites, there
are no comprehensive monitoring programs to assess its long-term variation nor
its seasonal patterns in broader areas of coastal Ecuador. The main objective
of the present study is to evaluate changes in Chl a concentration along the
coast of Ecuador and examine how these changes correspond to changes in Sea
Surface Temperature (SST). Eighteen o"shore and nearshore sampling sites
along the Ecuadorian coast were studied over 15 years, using satellite
measurements of MODIS-Aqua and MUR. Results show mean Chl a concentration in
coastal Ecuador is rather low (1.5 mg m−3 ) in comparison with other oceanic
regions. Puerto Bolivar, Gulf of Guayaquil and Esmeraldas were characterized by
the highest mean Chl a concentration; while Galera San Francisco Marine
Reserve, Cojimies and Cabuyal were characterized by the lowest. A positive
trend in Chl a concentration was detected at the southernmost (Puerto Bolivar
and Gulf of Guayaquil) and northernmost (Esmeraldas) study sites, with a
seasonal trend following the observed seasonal SST trend. Chl a is high in
areas under the in$uence of both the Humboldt upwelling system and river
discharge. The positive correlation between Chl a and SST is likely a response
to increased precipitation during warmer months. These results highlight the
importance of improving our understanding of the e"ects of climate change
on coastal PP, and the potential for these e"ects to in$uence the health
of commercial and threatened marine species. Further research should assess the
implications of changes in PP and SST for species of commercial and
conservation importance along the coast of Ecuador</span></p></div><div id="DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br> <table style="border-top:1px solid #d3d4de">
