Metadatabase view - dataset: Hydrochemical database of inflows and outflow of Võrtsjärv

General information

dataset entry ID:
FWM_2
name of the dataset:
full name of the dataset:
Hydrochemical database of inflows and outflow of Võrtsjärv
dataset short name:
Võrtsjärv in&out
type of dataset (more information):
environmental characteristics database
data type:
point data/observation data
short description of the dataset/summary:
This database contains the hydrochemical data (different C, P, N, Si forms) that were collected during the target-financed project SF0170011s08 ("Will climate change alter the relative importance of catchment and in-lake processes in the carbon balance of shallow lakes?") from Lake Võrtsjärv. We focus on time series of water samples in intensivly monitored main inflows and outflow of Võrtsjärv during six years (2008-2013). Samples were taken at least monthly. Additionally, the database contains information on environmental parameters (T, pH, oxygen, conductivity) measured in the field when water samples were taken. Supplementary hydrological data are separately available and can be linked to the hydrochemical database.
