Educational and other Activities

1. "Systematics and Ecology of Diatoms" Class at Iowa Lakeside Laboratory
   Our PEET award provides support for one student per year to assist in the annual diatom course at Lakeside Lab. This both enriches the class and provides experience in teaching diatom systematics. Matt Julius assisted the 1996 class and Becky Bixby assisted in teaching the 1997 class. This year we added a one-week Diatom Clinic primarily for senior investigators working on diatom related projects, and advanced research students. The first year clinic was considered a success, and we hope to continue the experiment next year.

Experience Working In Large Collections.

Our PEET award also provides categorical support for students to gain experience working in large collections. Group visits to the Academy of Natural Sciences, Philadelphia were conducted during spring break 1996 and spring break 1997. Matt Julius spent this past June working at the California Academy of Sciences.

Supplemental Award

Through a supplemental award, E. F. Stoermer and Mark Edlund were able to join an NSF-sponsored expedition organized by the Academy of Natural Sciences of Philadelphia to Lake Hovsgol, Mongolia. Here is a picture of the group, taken in Hatgal, Mongolia, E. F. Stoermer and colleague, pictures of Mark Edlund and Soninkhishig Nadair, collecting at Ar Hel, on Lake Hovsgol, Mark and our self-appointed guide and helper, Gambat collecting near the outlet of Lake Hovsgol, and Mark, with the fruits of his labors, after a long day in the field.

We recovered 150 collections which are presently under study. Some of the interesting species found include:

An unknown species of Stephanodiscus;

Didymosphenia siberica, a member of the Baikal endemic swarm;

Cymbella stuxbergii, also found in Lake Baikal.

Meeting of the North American Diatom Symposium

Although this meeting is not directly sponsored by PEET, students and faculty investigators have been active hosting it. NADS will be held at the University of Michigan Biological Station, Pellston. MI, 24-28 September. Dr. Charlie O'Kelly will attend to represent NSF, and the PEET Program in particular.
