Water and sediment (physico)chemical data 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 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. The purpose of the study serves a) availability of high-quality water and sediment data for this underrepresented region, and b) providing related baselines, c) testing the differences between tropical clearwater, blackwater and whitewater lakes, d) elucidating lake sensitivies particularly to drought phases and seasonal changes at large, and e) to obtain data that allows for improving lake management in the region.
