Spaulding is employed by the U.S. Geological Survey, working on the biogeographic distribution of diatoms across the country, particularly in relation to anthropogenic impacts of atmospheric deposition of nitrogen, sedimentation and nutrient loading. She served on the NSF Steering Committee for Deep Field Camps, Transantarctic Mountains (2011-2012), coordinating communication and research collaborations between biologists, geologists, glaciologists and others. Spaulding established the $10,000 endowed student fellowship (Reimer Scholarship) at Iowa Lakeside Laboratory. The scholarship is awarded to a student in the Ecology and Systematics of Diatoms course each year, based on merit. Spaulding serves on an ongoing basis to provide information on diatoms to professionals in academic institutions and government agencies including the US Forest Service, US Environmental Protection Agency, US Geological Survey, and National Park Service.
