[EN] The baseline of a specific variable defines the average behavior of that variable and it must
be built from long data series that represent its spatial and temporal variability. In coastal and marine
waters, phytoplankton can produce blooms characterized by a wide range of total cells number or
chlorophyll a concentration. Classifying a phytoplankton abundance increase as a bloom depends
on the species, the study area and the season. The objective of this study was to define the baseline
of satellite absorption coefficients in Todos Santos Bay (Baja California, Mexico) to determine the
presence of phytoplankton blooms based on the satellite inherent optical properties index (satellite
IOP index). Two field points were selected according to historical bloom reports. To build the baseline,
the data of phytoplankton absorption coefficients (aphy,GIOP ) and detritus plus colored dissolved
organic matter (CDOM) (adCDOM,GIOP ) from the generalized inherent optical property (GIOP) satellite
model of the NASA moderate resolution imaging spectroradiometer (MODIS-Aqua) sensor was
studied for the period 2003 to 2016. Field data taken during a phytoplankton bloom event on June
2017 was used to validate the use of satellite products. The association between field and satellite
data had a significant positive correlation. The satellite baseline detected a trend change from high
values to low values of the satellite IOP index since 2010. Improved wastewater treatment to waters
discharged into the Bay, and increased aquaculture of filter-feeding mollusks could have been the
cause. The methodology proposed in this study can be a supplementary tool for permanent in situ
monitoring programs. This methodology offers several advantages: A complete spatial coverage
of the specific coastal area under study, appropriate temporal resolution and a tool for building an
objective baseline to detect deviation from average conditions during phytoplankton bloom events.
