Integrative Oceanography Division

Professor of Oceanography, Emeritus

Research Interests

  • Large scale patterns in space and time and the California El Niño
  • Pelagic diversity maintenance
  • Pelagic biogeography
  • Climate and change in the California Current

Pelagic ecosystems are the largest and among the oldest on Earth. They process large quantities of atmospheric gases and produce at least half of Earth's organic compounds. Their diversity, structure, and productivity are strongly influenced by large-scale, time/space variations in oceanographic and atmospheric dynamics, including climate. I study these patterns.
