Suitable Location for Bathymetry Data?

Hi Forum,
I'm trying to find Bathymetry data for the West Coast of Scotland.
The following Earthdata Search query is a suitable area
[url]https://search.earthdata.nasa.gov/search?sb[0]=-7.77832%2C55.15913%2C-4.5791%2C58.74435&m=56.28910001188092!-8.947265625!6!1!0!0%2C2[/url]
I came across the General Bathymetric Chart of the Oceans (GEBCO) https://www.gebco.net/ which looks like it could be a good solution.
Does anyone know of any other resources or datasets they could point me to?
Thank you
Lewis

Hi Lewis,

You could try to look at the JPL TELLUS GRACE-FO Level-3 Monthly Ocean Bottom Pressure Anomaly (https://podaac.jpl.nasa.gov/dataset/TEL ... 06_OCN_v03) and JPL Mascon (https://podaac.jpl.nasa.gov/dataset/TEL ... ID_RL06_V2) products. They provide the water mass anomaly in equivalent water thickness units (cm) and could be useful datasets for your bathymetry study. If you need more information about the GRACE/GRACE-FO mission datasets, please let us know.

Best Regards,

Wenhao Li

Global bathymetry data products you might find useful are:

The General Bathymetric Chart of the Oceans (GEBCO) https://www.gebco.net/data_and_products ... etry_data/
where you can navigate to a subset tool at https://download.gebco.net/

The SRTM15_PLUS Estimated Topography of Tozer et al. https://topex.ucsd.edu/WWW_html/srtm15_plus.html which has an ascii download option, but is also accessible via ERDDAP (with subsetting) at https://coastwatch.pfeg.noaa.gov/erddap ... 5plus.html
