Description
Pacific Marine Environmental Laboratory (PMEL) submitted this dataset of moored current meter and pressure gauge observations from the Gulf of Alaska, collected between April 22 and September 26, 1989, as part of the Fisheries-Oceanography Cooperative Investigations (FOCI) project. Data are processed to the National Oceanographic Data Center (NODC) standard F015 and F017 formats, which contain time series of current vector components and seawater pressure. The data likely contain measurements of east-west and north-south current components, total pressure, and may include water temperature, salinity, and sensor metadata.
Use Cases
Analyzing tidal and storm-driven flows based on high-frequency pressure gauge measurements.
Modeling ocean circulation patterns using Eulerian current vector components (u, v).
Investigating relationships between water properties (temperature, salinity) and current dynamics.
Calibrating regional hydrodynamic models with in-situ mooring data from specific stations.
Strengths
Data collection uses a defined, fixed-point Eulerian method from moored instruments, providing consistent temporal measurements.
Time series are reported at high temporal resolution, typically at 10-15 minute intervals.
Data are processed to established NODC standard formats (F015, F017), ensuring a defined structure.
Collection covers a specific five-month operational period in 1989 for the FOCI project.
Limitations
Key metadata such as row count, file size, specific column names, and license are unavailable across all sources.
There is a conflict in the reported temporal coverage: the title states 1989-04-26 to 1989-09-26, while descriptions state 1989-04-22 to 1989-09-26.
