Judith is a Research Technician in the Research Centre for Oceanography Laboratory in Dunedin (Water World). Together with Kim Currie she operates the NZOA-ON (New Zealand Ocean Acidification-Observing Network). The Network consists of 11 coastal sites throughout the country where sampling partners (aquaculture and fishing industries, regional councils, and the Department of Conservation) take fortnightly bottle samples for DIC and alkalinity analyses. Sea FET pH sensors collect data to give high temporal resolution data.
Judith performs the alkalinity and DIC analyses, organises the logistics of the bottles and crates and manages the database. Judith also performs some commercial analytical services for industry and councils, prepares seawater-buffers and dye and certifies them. Judith comes from an analytical background (HPLC, LC-MS) in the Pharmaceutical industry.
