Biological Oceanography in the School of Ocean and Earth Science and Technology at the University of Hawaii BOD Faculty: Bienfang, Church, Drazen, Huntley, Johnson, Karl, Kemp, Selph, Smith, Steward, Waller, Wang, Weng Biological Oceanography in SOEST Biological oceanographers seek to understand how biology influences and responds to the ocean habitat and environmental variability. Breadth of biological oceanography research and education conducted at UH spans subcellular to ecosystems scales, including everything from viruses to whales. There is enormous potential for growth in the field, and our proximity to the sea provides SOEST with strategic opportunities.
