Sea level instrumentation A broad but sound understanding of the instrumentation used to identify sea level changes. Tides and sea level analysis A sound understanding of the theory of tides and sea level; sea level observing systems and quality control of sea level data. Updated version Interpret observational data to confirm or deny the arrival of a tsunami, and to determine its strength and arrival time at the observation site
Description of performance criteria • Compare observed and forecast sea level data to confirm or deny the arrival of a tsunami • Interpret observational data to determine tsunami strength and arrival time at the observation site • Incorporate limitations and errors in the data based on instrument response, accuracy and exposure • Sources of error include responses of different instruments, exposure in relationship to tsunami direction, reliability of instrument
Required underpinning knowledge, skills & systems • The ATWS Sea Level Observation System (ASLOS) - comprising coastal based sea level stations and deep ocean tsunami detection buoys • The theory of tides and sea level; sea level observing systems and quality of sea level data.
Regional variations • Differing sea level gauge types • Exposure of individual instruments with respect to the direction of the tsunami
Underpinning knowledge, skills and systems • Instrumentation used to identify sea level changes - characteristics and accuracies, oceanic and coastal instruments • The ATWS Sea Level Observation System (ASLOS) - comprising coastal based sea level stations and deep ocean tsunami detection buoys • Accuracy and limitations of the data – characteristics, exposure and reliability of individual observation sites • Sea level data access systems and site information
