Underwater microscopes: From the lab to the field




Dr. Jules Jaffe - Scripps Institution of Oceanography, San Diego


Although microscopic processes play a vital role in marine ecosystems and hence, global ecology, the in situ tools to observe them have not existed. Underwater microscopes can play an important role in observing such processes if the difficulties of providing undisturbed measurements can be overcome. In this talk Dr. Jaffe will describe recent work in his lab to improve the available technology to optically image some of the smallest biota in the ocean. This includes a recently developed web cam to view both zooplankton and phytoplankton, a portable, diver deployed underwater microscope for looking at benthic habitats, and a very recently developed 4 camera system that uses orthogonal holographic microscopes with a scanned thin laser sheet for fluorescence and an electronic lens for rapid focal plane scanning.
