GOAL OF THIS WORK
• Investigate the role of vertical positioning in determining habitat connectivity
Q: Does vertical positioning do this?

TARGET AREA
• Central California– Wind is dominant
• Mean wind stress– Along the coast– Stronger in summer,
weaker in winter
• Wind is variable– Larval dispersal in
