Abstract:
This dataset is part of a study investigating the freshwater Nitrososphaeria and their impact on the nitrogen cycling in lakes. It includes biweekly-monthly measurements of chlorophyll a concentrations in the upper water column (0-60 m) in Lake Constance (Germany) from November 2017 to November 2019. Water was taken with a Niskin bottle and filtered on board directly using Glasfiber filters.
