Climate Change Vulnerability
• Latitude, bathymetry, isolation, precipitation
![Page 7: Monitoring and Assessment in the Chequamegon Bay Area ... · Randy Lehr, Ph.D. Monitoring and Assessment in the Chequamegon Bay Area. Ecological Solutions Initiative. Chequamegon](https://reader034.fdocuments.net/reader034/viewer/2022042103/5e8130631a824e0325414749/html5/thumbnails/7.jpg)
Climate Change Impact Assessment
• Integrated Approach
– Monitoring
– Modeling
• Magnitude
– Changes in chlorophyll concentration/water clarity
• Mechanism
– Temperature vs. altered hydrology

Watershed/Tributary Monitoring
• Continuous discharge gage stations– 15-minute water levels
• Continuous data– Temp, SpCond, TSS
• Parameter loads (Grab/integrated samples)– TP, SRP, TN, NO3, TOC,
DOC, TSS, SSC, E. Coli, DO
• Input Data Sets
• Condition and open land assessments

Nearshore Monitoring
• Physical-chemical measurements– Vertical 1-m profiles:
Temp, pH, SpCond, DO, chl-a, turbidity, cDOM
– Vertical profile (SMB):• TP, SRP, TN, Chl-a, TSS• TP, SRP, TSS• TP, SRP, TSS
– Transect tows
• Monthly plankton tows
• Current profiles– ADCP
• Biweekly sampling
