Flowrates, gas bubble concentrations, water chemistry at Zelenka Beach. METZE 1 to 3 field works

Flowrates, gas bubbles concentrations, water chemistry at Zelenka Beach. METZE 1 to 3 field works Flowrate of the gas emissions were measured by professional divers using an calibrated volume and a timer. Pegaz tool was used by the divers to collect gas samples at different places sourunding a carbonate rock. Gas composition of the bubbles were measured using a gas chromatograph equipped with a TCD and FID, Stable isotops were measured at ISOLAB laboratory in Netherlands. Water samples were collected at the same time than the Pegaz were filled. Gas chromatograph with TCD and FID was used to measure the methane dissolved, Picarro detector was used to measure the stable isotops and liquid chromatograph was used to measure the ions.
