Nacote Creek Water Quality
Water quality instruments…
Temp pH Conductivity Salinity DO (Mg/L and %sat) Depth
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
Technical Reports - data maps using GIS software and analysis
Boating Safety – year round Medical needs – must inform me Eat properly day of trip Non-swimmers?
– Other concerns?
Boarding a boat – carefully While underway – PFD’s on Getting off the boat To assist or not to assist…fending off, etc.? Questions?
