Projects :: Western Pacific Diatoms Project

This project is a flora-in-progress, comprising images of the taxa of benthic marine diatoms as we discover them in tropical Western Pacific islands, especially Guam, Palau and Majuro. Whenever possible, taxa will be illustrated with photos of living material as well as acid-cleaned frustules in differential interference contrast light microscopy and scanning electron microscopy. There are also macro- and micro-photos of diatom assemblages in situ and under low power magnification. It is our intent to build a richly illustrated manual that can be kept current as taxa are added, names are changed and identifications corrected.

Acknowledgements: Microscopes used in Guam are part of a microscopy teaching facility at U. Guam that has been developed with grants from the National Institute of General Medical Science MORE program and the U.S. Dept. Education MSEIP program. CL and MS thank COMNAVMARIANAS for access to sites on Naval Facilities Guam, particularly our main study site, GU44 GabGab.
