DATA DISCLAIMER
1. IMPORTANT
Thank you for downloading data from the International Council for the Exploration of the Sea (ICES).
By downloading data from the ICES website and sub-domains [ices.dk] you are agreeing to the terms and conditions of use as described in this document and any documents referred to in this text.
Please read this before using the downloaded data, as this file contains specific information about the use of the data provided, limitations, and known issues. This file contains contact information regarding the origins of the data (where supplied) as well as how to cite these data in a publication or a data product.
This file is the counterpart to the data download file FILENAMEXXX
and was downloaded on DATETIMEXXX by IP IPADDRESSXXX .
Note that data download is built on the following national submissions:
COUNTRYLISTXXX
2. CONTACT INFORMATION
For feedback or queries about this data download, contact ICES at:
Email: [email protected]
Tel.: +45 3338 6700
Find more information at:
Web: https://www.ices.dk/marine-data/Pages/default.aspx
3. DATA SPECIFIC INFORMATION
Data from the trawl survey database are freely available for downloading.
Whilst the data have been extensively checked by both the supplying institutes
and ICES there are inherent flaws in gathering the information.
For example:
* In spite of the fact that now all bottom trawl surveys are in the same database
and often at least partially overlap in time period or area covered, there are
differences between the surveys that do not allow the combination of data from
different surveys in one analysis unless this point is specifically addressed.
* There is no guarantee that the gears deployed adequately sample all species
(e.g. catchability of flatfish in beam trawls is markedly higher than that of GOV).
It should be realized that each survey gear catches a gear-dependent subset
of the fish community.
* A common property of all surveys is that over time species determination skills
improve. As a result, new taxa will emerge in the dataset that were previously
reported as part of another closely-related taxon.
* Over time the sampling procedures, gear characteristics, timing of the survey
or the area covered may have changed thereby influencing the catches. Expert
advice recommendations are given in order to prevent bias in the analyses using
DATRAS catch data, caused by such factors.
* Please check on the submission status https://datras.ices.dk/Data_products/Submission_Status.aspx
before finalizing your report.
* Data product 'Litter Assessment Output' provides data mapping to Exclusive Economic Zones in the
field 'EEZ'. Layer with EEZ boundaries is from the http://www.marineregions.org/,
and ICES does not bear any responsibility for EEZ definitions.
When using this data product, please include acknowledgement of the EEZ data source as in the section below.
Thus users are urged to treat the data with caution. If the user has any queries
on the validity of the data or the conclusions to be drawn they should contact
either the ICES Secretariat or the Chairs of the relevant Working Group
(IBTS, BITS or BEAM)
4. TERMS OF USE:
ICES makes data available to users in an open, timely and easy way, but ICES remains dependent on data contributions.
- Correct and appropriate data interpretation is solely the responsibility of data users.
- Data Users must not expressly or otherwise imply ICES substantiation of their work, results, conclusions and/or recommendations.
- Data sources must be duly acknowledged.
- Data Users must respect any and all restrictions on the use or reproduction of data such as restrictions on use for commercial purposes.
- Data Users are obliged to inform ICES of any suspected problems in the data.
- Data Users are encouraged to inform ICES of possible sources of other relevant data.
The full ICES data policy and terms of use can be viewed at:

5. DATA ACKNOWLEDGMENT
Data sources should be acknowledged by a citation. Detailed information and examples of citations can be found in ICES Data Policy: https://ices.dk/marine-data/guidelines-and-policy/Pages/ICES-data-policy.aspx.
A minimum requirement citation would include the following:
