O16: Long Term Video EEG (AC/DC) Monitoring

Long term video electro-encephalographic (EEG) monitoring (LTM) is defined as the continuous and synchronized recording of EEG and multimedia to analyze brain abnormalities. A conventional LTM system continuously records EEG in the frequency range of 0.5-70Hz. The data synchronization, the high-volume data management, the system reliability as well as noise reduction remain significant challeng...

Long-Term Ecological Monitoring

Developments toward a low-cost approach for long-term, unattended vapor intrusion monitoring.

There are over 450 000 sites contaminated by chemicals in the US. This large number of contaminated sites and the speed of subsurface migration of chemicals pose considerable risk to nearby residences and commercial buildings. The high costs for monitoring around these sites stem from the labor involved in placing and replacing the passive sorbent vapor samplers and the resultant laboratory ana...

PSAMP Long-term Sediment Monitoring

PSAMP Long-term Sediment Monitoring As part of the Puget Sound Ambient Monitoring Program (PSAMP), the Washington State Department of Ecology sampled sediments at ten fixed stations each spring from 1989 through 2000 (Figure 1). Stations were chosen from a variety of habitats and geographic locations in Puget Sound. Sediments from each station were analyzed for particle size, organic carbon con...
