Studies of light and the distribution of Puget Sound sea squirts: A vehicle for coupling research programs and undergraduate education at the Shannon Point Marine Center.Brian Bingham, Ph.D. Wednesday, June 13, 2001
Research on this topic has proven an excellent way to involve university students in scientific research. The research questions touch on issues ranging from ozone depletion and global climate change to basic ecology and conservation of marine diversity. As such, the work appeals to students with a variety of backgrounds and interests. Studying sea squirts and light, undergraduate students at the Shannon Point Marine Center are learning about research while contributing to our understanding of marine systems.

Research has
clearly demonstrated the harmful effects of UV radiation. UV affects
reproduction, growth, and survival of many plants and animals. Work at the
Shannon Point Marine Center is demonstrating that sea squirts are
particularly vulnerable. Solar radiation can have rapid lethal effects on
eggs, embryos, larvae, juveniles, and adults. The damaging effects are not
restricted to UVB. UVA and low-wavelength visible light can also be very
harmful. The vulnerability of sea squirt species varies enormously,
particularly in regards to the life-history stages that are most affected.
Differences in sensitivity are associated with specific anatomical,
behavioral, and life-history traits of individual species.
