Description

This dataset includes dissolved nutrient concentrations from seawater collected in the Norwegian National Mesocosm Centre at the Espegrend (Espeland) Marine Biological Station near Bergen, Norway, in May 2017.

Methods & Sampling

Dataset acquisition description

Samples for dissolved nutrient analysis were collected by filtering through a pre-combusted GF/F filter (pore size ~ 0.7 µm) into acid washed Falcon tubes. Samples were frozen at -20°C and analyzed for nitrate+nitrite, ammonium, and orthophosphate at the Rutgers University Nutrient Analysis Facility.

Data Processing Description

Dataset Processing Description

BCO-DMO Processing Notes:
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
- re-formatted date from d-Mon-yy to yyyy-mm-dd
- replaced commas with semicolons
- reordered columns; sorted records by Treatment, Bag#, Depth
- changed column name Depth to Depth_description (shallow, deep) and added column Depth (1, 5)
