Oceanographic CPIES Data from the Cascadia Subduction Zone, 2017

NOAA_NCEI provides a data set containing vertical acoustic travel time, bottom pressure and temperature, and near-bottom current and temperature from four current and pressure recording inverted echo sounders (CPIES). The data were collected near the Cascadia subduction zone offshore of Oregon from 2017-04 27 to 2017-11-11, with additional measurements from two PIES and a separate current meter mooring. The CPIES data are provided in NetCDF format as the highest quality versions with minimal processing.

Use Cases

• Modeling ocean circulation patterns based on near-bottom current and temperature measurements.
• Analyzing acoustic travel time variations for underwater sound propagation studies.
• Studying seafloor pressure changes in relation to tectonic activity in the Cascadia subduction zone.
• Calibrating oceanographic models using high-quality, minimally processed CPIES data.

Strengths

• Data are described as the highest quality versions with the least amount of processing.
• Includes measurements from four CPIES instruments, two PIES instruments, and a separate current meter mooring.
• Covers a specific time range from 2017-04-27 to 2017-11-11 in a defined geographic area.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2017-11-11 00:00:00; freshness should be verified.
• Row count and file size are unknown, which may limit suitability assessment.
