The backend need to be updated to allow the users to query the data base based on:

1) location(point & polygon both predefined and arbitrary)

• - predefined (state, region) user defined (my favorite)

2) based on data type

• - N, TP, Chl a , DO, temp

3) Data source

• - EPA point, EPA seabird, triaxis, USGS, state data, all

4) Time

• - Season(spring, summer, fall), date/time range
