Data Adequacy Reports

The Data Adequacy Report (DAR) provides a view of the monitoring effort in the Arctic sea basin, with the aim to show how well the available marine data meets the needs of users. The monitoring effort is elaborated from three different viewpoints, which are clearly distinguished in three parts:

  1. the needs of users (e.g. fisheries managers, coastal protection authorities, ports);
  2. separate parameters (e.g. temperature, bathymetry, sea level rise);
  3. the purposes for which data is used (e.g. marine spatial planning, assessment of (potential) MPAs, assessment of navigational risks).

As part of the Arctic SBC project, a structure for collecting information on data adequacy was developed: the Content Management System (CMS). The structure of the CMS allows for the presentation and analysis of the quality and adequacy of the assessed data sets, from many different angles and perspectives, of which the main are presented in this DAR. The literature review and the challenges as registered in the CMS were used as input.

In general we have found that the datasets that are available and have been evaluated in the present study usually have a quality that has a limited match with the requirements for the purpose for which it is used. For the spatial and temporal aspects, in most cases there was an association between the quality (i.e., resolution and coverage) and data requirements (match of quality for a specific purpose). As (for at least most challenges in the present project) the focus is on the entire Arctic region, a partial mismatch can be expected for many European data sources (such as EMODnet) which only focus on the European part of the Arctic. Only a small fraction of datasets were classified as unsuitable for specific purposes.

Within the scope of this study we identified some data sources and data sets that are particularly ‘popular’ for Arctic based studies, which indicates that those datasets are reused. It was also found that the original purpose for which data was generated is often not reported or not known. In case the purpose  is known, data sources and data sets are often (re)used for the same purpose. For some original purposes, the datasets are reused for multiple additional purposes and some additional purposes use data generated with multiple original purposes.

This first DAR will be reviewed by the Commission and the Panel and their input will be addressed in a second DAR.
