Yellow Springs Instruments (YSI) Discrete sampling instruments (600 series)
– Used to “spot” sample– Could be used on a weekly basis– $3000-$5000
Unattended sampling instruments (6000 series) – Left in the field to collect data on a user
determined interval– Requires secure mounting– $5000-$8000
How can we display the data collected?

Geographic Representation of Measurements at Sampling Stations in the Mullica River - Great Bay Estuary
ArcView was used to create a macro program– spatial data from the field – table development in Excel– table import to ArcView software
Results of macro program– generates a map with sampling sites noted– creates charts of selected variables vs. sites– produces report quality map with data charts, north
arrows, scale, and titles
