Hydrographical profiles from Amazonas lakes, Brazil - rainy and dry seasons 2021 - 2023

DOI

Water (physico)chemical and sediment chemical data from shallow tropical lakes and some piscicultures are available. In 5 subsequent field campaigns in both dry (3x) and rainy (2x) seasons from September 2021 to August 2023, we targeted five lake basins, including a large reservoir (Balbina), and 2 pisciculture sites in Amazonas state, Brazil. The lakes are Caldeirao and Jandira (blackwater), and Grande and Iranduba (whitewater), all on Iranduba peninsula to the WSW of Manaus. The two piscicultural sites are near the town of Rio Preto da Eva, NE from Manaus, and comprise various basins each with site 1 being used for raising young fish and site 2 for the production of edible fish.Repetitive hydrographical profiles were taken each time from the same lake positions with a multi-parameter probe (Manta +35, Eureka), featuring water temperature (degrees C), pH, electrical conductivity (EC, µS/cm), turbidity (NTU), oxygen concentration (mg/l) and saturation (%), and depth (cm).
