Ms. Kate Hall holds a BS degree in Environmental Science through the Western Washington University Huxley Environmental Studies program. Her focus has been on stream ecology, water quality, toxicology, risk assessment, physical oceanography, and species and habitat monitoring. She served her internship at the Battelle Marine Sciences Laboratory and was hired full-time to assist in conducting bioassays in the toxicology laboratory. Since then she has evolved her capabilities to work in multiple groups within MSL and Richland. Her duties include laboratory setup, instrument calibration, organism receiving and animal care, test initiation, monitoring and termination, and data collection. She also oversees the maintenance of a variety of test organism cultures such as of Leptocheirus plumulosus, Pimephales promelas, and Daphnia Magna. Her field work duties have included inventory management, sample and data collection, equipment deployment, maintenance and retrieval, as well as surgical implantation of acoustic tags in juvenile salmon.

Ms. Hall is proficient at using several instruments involved in daily laboratory and field tasks, including dissolved oxygen meters, pH meters, thermometers, refractometers, ammonia meters, light meters, flow meters, HOBO data loggers, and the YSI data sonde, which takes simultaneous readings of salinity, conductivity, temperature, DO, and pH. Other equipment includes proportional diluters, balances, environmental chambers, various sizes and types of pumps, underwater surveillance equipment, remote environmental monitoring unit system (REMUS) and autonomous acoustic receivers. Her field work often includes working on and operating various types of research vessels and SCUBA work.

Ms. Hall is also a member of the MSL dive team and certified boat operator. She holds certificates in open water diver, advanced diver, rescue diver, first aid/CPR, SCUBA first aid, and diver emergency oxygen administration. She also holds a certificate as a service technician for the Interspiro/Ocean Technology Systems Divator MKII, the mask used by the MSL dive team. Her duties as a dive team member include research support through habitat monitoring, surveying and restoration, equipment deployment, sample and data collection, as well as servicing dive gear. As a Battelle qualified boat operator, she holds a boat safety education card and has completed America’s Boating Course and met all other requirements set by Battelle.

Some of her most recent projects involve working with principal investigators on the juvenile salmon acoustic telemetry (JSAT) program. This program uses acoustical tags and receivers to track salmon as they migrate out of the Columbia River system. Duties for this project include intensive field work to surgically implant the acoustic tags in the fish and to deploy service and retrieve the autonomous nodes and collect data. Ms. Hall also performs the post season acoustic receiver performance testing in the lab.
