Abstract:
High-frequency data collected continuously over a multiyear time frame are required for investigating the various agents that drive ecological and hydrodynamic processes in estuaries. Here, we present water quality and current in-situ observations from a fixed monitoring station operating from 2008 to 2014 in the lower Guadiana Estuary, southern Portugal (37°11.30' N, 7°24.67' W). The data were recorded by a multi-parametric probe providing hourly records (temperature, salinity, chlorophyll, dissolved oxygen, turbidity, and pH) at a water depth of ~1 m, and by a bottom-mounted acoustic Doppler current profiler measuring the pressure, near-bottom temperature, and flow velocity through the water column every 15 min. The time-series data, in particular the probe ones, present substantial gaps arising from equipment failure and maintenance, which are ineluctable with this type of observations in harsh environments. However, prolonged (months-long) periods of multi-parametric observations during contrasted external forcing conditions are available. The raw data are reported together with flags indicating the quality status of each record. River discharge data from two hydrographic stations located near the estuary head are also provided to support data analysis and interpretation.

Comment:
Multiyear (2008-2014) water quality and current data from a fixed monitoring system operating (SIMPATICO) at the lower Guadiana Estuary, southern Portugal (37.188048º -7.411062°). The data were recorded by:
- A multi-parametric probe providing hourly records of temperature, salinity, chlorophyll, dissolved oxygen, turbidity, and pH at a water depth of ~1 m.
- A bottom-mounted acoustic Doppler current profiler (ADP) measuring the pressure, near-bottom temperature, and flow velocity through the water column every 15 min.
The datasets are divided into 12- to 23-month-long (non continuous) time-series that are split by large gaps arising from equipment failure and maintenance. The raw data are reported together with flags reporting quality control results. River discharge data are also provided to support data analysis.
