Abstract:

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.

Sediment cores were taken once at profundal positions with a custom-built gravity corer, sliced in the field into 2.5 cm sections, and stored cool in PE-containers. Their subsequent analysis covered a similarly wide bandwidth of major, minor, and trace elements after drying, milling to analytical grade (<63 µm), determined by ICP-OES and ICP-QMS (as above, yet after full, multi-acid digestion (MA-Dig)), and by wavelength-dispersive XRF (S8 Tiger, Bruker) on glass-fusion discs (GFD) and pressed powder pellets (PPP). CNS was determined by elemental analysis (El Cube, Elementar).
