| contents | 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 locations in Amazonas state, Brazil. The lakes are Caldeirão and Jandira (blackwater), and Grande and Iranduba (whitewater), all on Iranduba peninsula to the WSW of Manaus. The two piscicultural locations are near the town of Rio Preto da Eva, NE from Manaus, and comprise various basins each with location 1 being used for raising young fish and location 2 for the production of edible fish. Water samples from different depth were taken repetitively with a contamination-free sampler. These samples were treated onboard (membrane filtration, acidification for cations, cooling) and stored in ultrapure acid-cleaned HDPE containers. Ion chromatography (IC, Metrohm), inductively-coupled optical emission spectrometry (ICP-OES, Perkin Elmer), also coupled with mass spectrometry (ICP-QMS, Perkin Elmer Elan) was used for the water samples. |
