1. color coded according to mean salinity Low Medium High Bottom Dissolved Oxygen Bottom Salinity ChesROMS + 1-term oxygen model For variables with higher standard deviation, target is less stringent test of model skill

2. color coded according to DO level color coded according to bottom depth color coded according to mean salinity Low Medium High Low Medium High Shallow Mid Deep For bottom oxygen, model does best in deep, low oxygen waters Dissolved oxygen at bottom of water column

3. color coded according to DO level color coded according to bottom depth color coded according to mean salinity Low Medium High Low Medium High Shallow Mid Deep Does not do as well in pycnocline, perhaps because stdev of data is lower. Pycnocline oxygen is most accurate low oxygen waters Dissolved oxygen at pycnocline

4. Next Steps in Hypoxia Comparison… Which effect is greater – changing circulation model or changing hypoxia model? 1. ChesROMS + 1-term hypoxia 2. EFDC + 1-term hypoxia 3. ChesROMS + multi-term hypoxia
