Austin Marine Science Institute in\ \ Port Aransas, TX. Steve\u2019s research focuses on natural and anthropogenic\ \ tracers in aquatic systems and the influence of UV radiation on both biology\ \ and chemistry. While in Georgia, Steve developed an appreciation for aquifers\ \ including their importance as an ecosystem and for supporting human life." additionalType: personal statement email: sopsahl@usgs.gov hasCredential: [] hasOccupation: - '@type': OrganizationalRole affiliatedOrganization: '@type': Organization name: Oklahoma-Texas Water Science Center url: https://www.usgs.gov/centers/oklahoma-texas-water-science-center roleName: Hydrologist startDate: '2024-05-12T16:12:17.609189' identifier: - '@type': PropertyValue propertyID: GeoKB value: https://geokb.wikibase.cloud/entity/Q140162 jobTitle: Hydrologist knowsAbout: [] memberOf: '@type': OrganizationalRole member: '@type': Organization name: U.S. Geological Survey name: staff member startDate: '2024-05-12T16:12:17.606458' name: Stephen Opsahl url: https://www.usgs.gov/staff-profiles/stephen-opsahl
