PhD: University College Cork, Ireland • Marine Biology
BSc: University College Cork, Ireland • Applied Ecology

Ian is a new post-doc working on a project examining the extent and composition of fouling communities entering the Lower Columbia River on the hulls of ships. Much of the recent work carried out on species introductions and vector science in marine systems has focused on the importance of ballast water in transferring species around the world. Much less attention has been given to hull mediated transfers, and this is a first attempt to quantify the extent of biofouling transfers into the Lower Columbia River. Samples will be taken directly from ships, both underwater and from occasional dry-docking periods, as well as from archival video footage provided by maritime companies in the region. Patterns of fouling assemblage distribution occurring on existing man-made structures and other hard-bottom substrata will also be surveyed.

Robyn Draheim is a research assistant with the Center for Lakes and Reservoirs. Her background is in benthic ecology and estuarine systems and she has been involved with invasive species issues since 1997. She coordinated the Middle Columbia River Aquatic Nonindigenous Species Survey (an extension of a similar project on the Lower Columbia River summarized here) and assists with the implementation of the Oregon ANS Management Plan. She also provides education and outreach on Mitten crabs, New Zealand mudsnails, etc.

BS:Humboldt State University • Aquatic Systems Analysis

Rich is a research assistant for the Environmental Protection Agency’s Nutrient Criteria Development program for lakes and reservoirs. The current year’s research will develop a classification scheme for reservoirs in EPA region 10. Rich is also updating the Atlas or Oregon Lakes to reflect modern data collection and publication techniques.
