Daily Bottom Temperature for the Northeast U.S. Shelf, 1959-2020

A high-resolution bottom temperature product for the northeast U.S. continental shelf from 1959 to 2020. The dataset combines a regional ocean model (ROMS-NWA) with a global assimilated model (GLORYS12v1), bias-corrected using monthly decadal climatologies from observations. Model skill was assessed with in situ observations, as presented in du Pontavice et al. 2023.

Use Cases

• Modeling climate change impacts on marine habitats based on the long-term (1959-2020) temperature record.
• Analyzing seasonal and decadal bottom temperature variability for the Northeast U.S. Shelf.
• Validating regional ocean circulation models using the combined observational and model-based product.
• Assessing thermal habitat suitability for commercial fish species based on the high-resolution (1/12 degree) gridded data.

Strengths

• Long-term temporal coverage spanning 61 years (1959-2020).
• High spatial resolution at 1/12 degree for the Northeast U.S. continental shelf.
• Model skill was assessed using a large number of in situ observations, as referenced in du Pontavice et al. 2023.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data format is listed as PDF and HTML, which may limit direct machine-readability for analysis.
