Seasonal high-resolution sensor data for pCO2, pCH4, O2 and temperature/salinity within the Danube Delta, Romania in May 2017

Flow-through pCO2, O2 and some CH4 measurements throughout the Danube River Delta in spring (17.05.2017 - 26.05.2017). Surface water flow-through system set up on a houseboat (see Canning et al., 2020). All running on the same water at almost the same time (within seconds), therefore all joined together into each data set. Gaps from sensors depend on when they were logging. For the pCO2, some gaps will be due to periods of zeroing and flushing. Depth of pumps: approx. 75cm Flow rate: ~ 5-6 L/min flow readings logged for Aug and Oct. May data was manually logged and recorded, therefore potential discrepancies. All data was processed following Canning et al., 2020 (In Review). Seasonal sensor data are in separate files.
