1.Providing data QC as well as outlier flagging and filtering. 2.Providing data file aggregation and production of large integrated datasets. 3.Providing production of time-series plots, maps, sections and animated 3D plots.

ODV collections are created for every data type found. ODV collections are created for every data type found. Data of a given file are imported into the corresponding ODV collection.

When aggregating SDN files different BODC parameter/unit codes are maintained as separate variables (e.g., 3 oxygen variables). User may combine separate variables by means of aggregated derived variables (e.g., 1 oxygen variable for scientific usage).

Aggregated derived variable Oxygen [ml/l] = 1 * (DOX1 DISSOLVED OXYGEN ml/l) * (DOX2 DISSOLVED OXYGEN micromole/kg) * (DOXY DISSOLVED OXYGEN millimole/m3) + 0 Merging Principles: Merging Type (exclusive use of first available value, average over all available values) Order of input variables matters (in case of eclusive merge) Standard or user-specified conversion formulas Quality flag inheritence
