Diatoms are the main component of phytoplankton and thus form the basis of the marine food chain. Because they carry out photosynthesis with their chloroplasts, they account for a large proportion of ...

We examine diatoms via research-grade microscopes. Our lab also houses several thousand glass microslides and archived material, primarily from arctic, alpine and Antarctic lakes and streams. Our work ...
