Cassandra M. Smith, Ph.D.
Cassandra is a Physical Scientist with the USGS Volcano Hazards Program.
Dr. Smith was an NSF funded postdoctoral fellow with the USGS Alaska Volcano Observatory in Anchorage AK developing spatiotemporal relationships between globally detected volcanic lightning and eruption cloud dynamics.
Additionally, Cassandra previously worked on natural hazard resilience at the Department of State.

Temporal and spatial monitoring of cyanobacterial blooms at Willow Creek Reservoir, North-Central Oregon Temporal and spatial monitoring of cyanobacterial blooms at Willow Creek Reservoir, North-Central Oregon
The U.S. Geological Survey (USGS) and U.S. Army Corps of Engineers (USACE) investigated the spatial and temporal dynamics of cyanobacterial (blue-green algal) blooms in Willow Creek Reservoir in north-central Oregon in 2015–16. A combination of cameras and water-quality monitoring equipment was used to assess the frequency and duration of blooms and their effects on water quality. A...

Klamath River Basin water-quality data Klamath River Basin water-quality data
The Klamath River Basin stretches from the mountains and inland basins of south-central Oregon and northern California to the Pacific Ocean, spanning multiple climatic regions and encompassing a variety of ecosystems. Water quantity and water quality are important topics in the basin, because water is a critical resource for farming and municipal use, power generation, and for the...

Investigating the origin of continual radio frequency impulses during explosive volcanic eruptions Investigating the origin of continual radio frequency impulses during explosive volcanic eruptions
Volcanic lightning studies have revealed that there is a relatively long‐lasting source of very high frequency radiation associated with the onset of explosive volcanic eruptions that is distinct from radiation produced by lightning. This very high frequency signal is referred to as “continual radio frequency (CRF)” due to its long‐lasting nature. The discharge mechanism producing this...
