Description
A Finite Volume Community Ocean Model (FVCOM) simulation provides hourly data on water levels, velocity, temperature, and salinity for the Northeast US, including the Gulf of Maine. The model was configured and run by Dr. Changshen Chen at the University of Massachusetts Dartmouth's School for Marine Science & Technology. Output covers a multi-decadal period from 1984 to the present, with saved hourly data from August 21, 2009, to June 17, 2022.
Use Cases
Analyzing tidal and storm surge patterns based on simulated water levels.
Studying long-term temperature and salinity trends in coastal waters.
Validating other oceanographic models against a high-resolution regional hindcast.
Investigating ocean circulation and current velocity in the Gulf of Maine.
Strengths
Model output spans a multi-decadal period from 1984 to the present.
Data was saved at hourly intervals for over 12 years (2009-08-21 to 2022-06-17).
The model uses a variable-resolution triangular mesh with 45 vertical layers.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count and total data size are unknown, which may limit suitability assessment.
