ATLANTIC_CH10_Product_2 / Digital bathymetry uncertainty covering the North Atlantic, and a representative sample area within the North Atlantic.
This product is a map of the uncertainty of available digital bathymetry measurements for the North Atlantic Ocean. This is done for a spatial resolution feasible for this large area (25km x 25km). It is designed to assess the quality of the bathymetry readings with a view to supporting assessments of future need. The product is formulated through a number of characteristics of the data including age of measurement and slope.

This EMODnet Atlantic Checkpoint data product (the “Product”) is the result of a “challenge” stress test specified by the call for tenders No MARE/2012/11. The challenge partners ( "the producer") were commissioned to perform a number of tests to evaluate marine data according to set user requirements. This product and any resultant data and metadata produced is a consequence of these tests and provided for interest only. The Product is provided on an “as is” basis, and the producer disclaims any and all warranties, conditions, or representations (express, implied, oral or written), relating to the Product or any part thereof, including, without limitation, any and all implied warranties of quality, performance, suitability or fitness for a particular purpose to the full extent permitted by law. The Producer and the Atlantic Checkpoint partners accept no liability for loss suffered or incurred as a result of reliance on the Product or any output of its use. The Producer shall not be liable for any economic loss, loss of profit, loss of business or contract, depletion of goodwill or otherwise, in each case whether direct, or indirect or any indirect loss whatsoever (howsoever caused) including loss or damage suffered as a result of an action brought by any person which arise out of or in connection with the use of the Product or inability to use the Product

It is possible to build a coarse uncertainty grid for the entire North Atlantic Ocean. However, the value produced is relative and does not indicate a quantitative error. Data offered in standard formats. Limitations with downloading large quantities.
Metadata is also missing and had to be approximated. Metadata was varied and complex, sometimes even within individual data products. Much metadata was missing and incomplete. On the whole, metadata was non-standard and variable leading to difficulties producing data products with multiple sources. It was also necessary to infer certain attributes (such as method) from the data values themselves by looking at the density and form of the depth readings.
For each input dataset, the reported findings are as follows:
- GEBCO Source Identifier Grids. It was possible to assign a value based on whether the bathymetry came from a particular source.
- EMODnet : Usability problems prevented EMODnet metadata being obtained in the quantities necessary.
- USGS : Extensive metadata available by survey and also regarding dataset compilation.
- CHS : Limited metadata available, not much useful information. Information was inferred from the characteristics of the data."
