I am generally interested in the relationships between atmospheric gases and groundwater, as mediated by the interactions in the vadose zone, the layer of the ground that water must pass through before it enters an aquifer.I have a background in experimental atmospheric chemistry, having worked with several groups on topics including ocean fertilization, biogeochemical impacts to atmospheric chemistry, oceanic emissions of halocarbons to the atmosphere, instrument validation studies, long term observations, anthropogenic emissions, and air quality measurements.Dissolved Gases are important chemical tracers in groundwater systems. They provide information about groundwater age, aquifer mixing, and the climate conditions when water entered the aquifer. This information can be used to study issue of groundwater availability, quality, and quantity. Additionally direct measurements of these properties can be used to validate groundwater model output and improve model algorithms, allowing more accurate assessment of aquifer systems. I have designed, constructed several noble gas mass spectrometer and GC systems to measure dissolved fixed gases (O2, N2, He, Ne, Ar, Kr, and Xe) to assess groundwater recharge temperatures more accurately, and I am studying the behavior of various anthropogenic compounds in the groundwater system.In pursuit of these research goals, I have developed novel and customized analytical systems and sensors for research and production operations. Among others, these include an automated economical quadruple mass spectrometer based noble gas analyzer, a dual channel GC-FID-AED system for measuring trace hydrofluorocarbons (as novel groundwater age tracers) and trace hydrocarbons (to better understand hydrocarbon geochemistry, a highly automated multi-port noble gas analyzer for tritium-helium dating and noble gas concentrations in groundwater, a self contained low cost pCO2 sensor, and GC-TCD system for measurements of He/Ne in groundwater samples. additionalType: personal statement email: khaase@usgs.gov hasCredential: [] hasOccupation: - '@type': OrganizationalRole affiliatedOrganization: '@type': Organization name: Water Resources Mission Area url: https://www.usgs.gov/mission-areas/water-resources roleName: Research Chemist startDate: '2024-05-12T15:18:10.163838' - '@type': OrganizationalRole affiliatedOrganization: '@type': Organization name: Reston Stable Isotope Laboratory (RSIL) url: https://www.usgs.gov/labs/reston-stable-isotope-laboratory roleName: Research Chemist startDate: '2024-05-12T15:18:10.171656' identifier: - '@type': PropertyValue propertyID: GeoKB value: https://geokb.wikibase.cloud/entity/Q46482 - '@type': PropertyValue propertyID: ORCID value: 0000-0002-6897-6494 jobTitle: Research Chemist knowsAbout: - '@type': Thing additionalType: self-claimed expertise name: Environmental tracers research - '@type': Thing additionalType: self-claimed expertise name: Atmospheric Chemistry - '@type': Thing additionalType: self-claimed expertise name: Gas Chromatography (GC) Method and Design - '@type': Thing additionalType: self-claimed expertise name: Mass Spectrometer Systems Design, Development and Integration - '@type': Thing additionalType: self-claimed expertise name: Vacuum Systems - '@type': Thing additionalType: self-claimed expertise name: Process and Instrumentation Automation - '@type': Thing additionalType: self-claimed expertise name: Trace Gas and Dissolved Trace Gas Analysis - '@type': Thing additionalType: self-claimed expertise name: Air Water Interaction - '@type': Thing additionalType: self-claimed expertise name: Groundwater Dating - '@type': Thing additionalType: self-claimed expertise name: Electronics Prototyping memberOf: '@type': OrganizationalRole member: '@type': Organization name: U.S. Geological Survey name: staff member startDate: '2024-05-12T15:18:10.160842' name: Karl B Haase, Ph.D. url: https://www.usgs.gov/staff-profiles/karl-b-haase
