Infrared images of the California Current
Is it really
the ocean?
Lesson #1: Advising Students

Don’t be too available

Strategies for finding Myrl or solve the
problem yourself
Provide plenty of moral support
Corollary: Let someone else do the
serious criticism (Russ?)
“It looks real, so assume it is”

Lesson #2: Analyzing Observations

Focus on understanding processes
Corollary: let someone else “ground truth”
the data

Don’t micromanage the research
Corollary: “go ask Russ or Bob Parker”

Vicarious enjoyment of results

Core of wind jet moves offshore, expanding region of positive curl
and upwelling -- current core moves offshore with curl
