Working on aggregating information in the data over either time or space to generate visualizations and summary statistics that identify and convey broad trends. Keeping record of plots generated

Grouped bottle by year and quarter, summarized oxygen by averaging over all stations sampled in that given time point, plotted that against year.

Next step is to generate the same plot using data only from years in which all quarters were sampled — some years in the 70's and 80's have only 1 quarter sampled

[mgupta701]

Selected only years that had all quarters sampled to generate same graph as previous comment

This plot displays the same data but separates out the trends for each quarter
