Description

Bubble flux measurements and concentrations at two sites on the Virginia Eastern Shore, July 2017.

Methods & Sampling

Gas fluxes from simple inverted bubble traps described in:

Oxygen % of samples was determined by isotope ratio mass spectrometry (IRMS) and an oxygen optode.

These data will be published in Long MH, Sutherland K, Wankel SD, Burdige DJ, Zimmerman RC. Ebullition of Oxygen from Seagrasses under Supersaturated Conditions. In Revision: Limnology and Oceanography.

Data Processing Description

BCO-DMO Processing:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- reduced precision of O2_Ar and d18O to match input
- split date_time column into separate date, time and ISO_DateTIme_Local columns
- added lat and lon columns from associated dataset
