An award is made to Walla Walla University to support an upgrade of the seawater system at Rosario Beach Marine Laboratory (RBML) that will include new additions to filter and sterilize seawater before and after it passes through tanks holding live marine organisms. The current system pumps unfiltered seawater from Rosario Bay into holding tanks for teaching and research, and returns it untreated to the bay, raising risks of transferring invasive species or pathogens into or out of the lab. The current system is impaired by sediment buildup that can disrupt water flow, harm animals and disrupt experiments. The system upgrade will address these issues and support certification as a terminal quarantine facility, enabling the lab to house non-native species. These upgrades will allow for the continuation of critical research at RBML, expand training and research opportunities for undergraduate and graduate students, reduce the time and expertise required for animal care, and allow RBML to host more external researchers. Upgrades will also support K–12 teacher workshops, student programs, and engagement with the local community and conservation groups. The upgraded system will enhance RBML’s ability to support critical research on marine responses to environmental change. RBML is located in the Salish Sea, an area already experiencing future-predicted levels of ocean acidity and hypoxia and is therefore well positioned to study the impacts of environmental change on marine org
