(~40min)
Discussion of an ETM paper(~1h)
Activity towards understanding
Columbia River ETM
• Summary presentation (10 min• Open discussion (40 min)• Umbrella questions (10 min)
• Contextual forcing, dynamics and governing equations • ETM sources and characteristics• Observation and prediction tools• ETM experiments and analyses
• Part of lecture (occasionally)• Homework assignments (typically)

Lecture 2
• Discussion: Lin and Kuo 2003
• Context for understanding the Columbia River ETM: a brief introduction to the river-to-ocean system and to the SATURN/CORIE observatory (conclusion)
• Introduction to governing equations

Framing the course: umbrella questions
• What are ETMs?
• Where do ETMs occur?
• What causes ETMs?
• Why are ETMs important?
• How can ETMs be observed/modeled?
• How do ETMs vary in time?
• How do ETMs affect microbial communities, estuarine productivity and fisheries ?
• How are ETMs affected by climate and human activities?
• What do ETMs look like in the Columbia River estuary?
