abstract = "The Nhecolandia region, located in the southern
portion of the Pantanal wetland area, is a unique
lacustrine system where tens of thousands of
saline-alkaline and freshwater lakes and ponds coexist
in close proximity. These lakes are suspected to be a
strong source of greenhouse gases (GHGs) to the
atmosphere, the water pH being one of the key factors
in controlling the biogeochemical functioning and,
consequently, production and emission of GHGs in these
lakes. Here, we present a new field-validated
classification of the Nhecol^andia lakes using water pH
values estimated based on a cloud-based Landsat (5 TM,
7 ETM+, and 8 OLI) 2002-2017 time-series in the Google
Earth Engine platform. Calibrated top-of-atmosphere
(TOA) reflectance collections with the Fmask method
were used to ensure the usage of only cloud-free
pixels, resulting in a dataset of 2081 scenes. The pH
values were predicted by applying linear multiple
regression and symbolic regression based on genetic
programming (GP). The regression model presented an R 2
value of 0.81 and pH values ranging from 4.69 to 11.64.
A lake mask was used to extract the predicted pH band
that was then classified into three lake classes
according to their pH values: Freshwater (pH < 8),
oligosaline (pH 8-8.9), and saline (at least 9). Nearly
12,150 lakes were mapped with those with saline waters
accounting for 7.25percent. Finally, a trend surface
map was created using the ALOS PRISM Digital Surface
Model (DSM) to analyse the correlation between
landscape features (topography, connection with the
regional drainage system, size, and shape of lakes) and
types of lakes. The analysis was in consonance with
previous studies that pointed out that saline lakes
tend to occur in lower positions compared to freshwater
lakes. The results open a relevant perspective for the
transfer of locally acquired experimental data to the
regional balances of the Nhecolandia lakes.",
