The National Geoscience Data Centre (NGDC) collects and preserves geoscientific data and information, making them available to a wide range of users and communities. NGDC is recognised as the NERC Environmental Data Centre for geoscience data.
Please use the NGDC data deposit application (portal) to deposit digital files with NGDC.
Data donations should comply with the following NGDC terms and conditions and guidelines:
- NGDC terms and conditions (372 KB pdf)
- NGDC data value checklist (92.2 KB pdf)
- Depositing sample analysis data (406 KB pdf)
- Data sharing agreements
Your data should:
- consistently include header rows and scientific units relating to any measurements
- document details about any scientific standards, instrumentation, software, code or data collection methodologies used
- be provided as a final version and therefore complete
- ideally be ‘open’ data allowing it to be discovered and re-used by other interested parties
- have all acronyms explained and use consistent naming conventions – guidance on naming strategy
When packaging up your data to deposit them with NGDC, you should consider the following.
Your data should be grouped appropriately with a common geographical location or science-specific topic, e.g. ‘two site investigations for Smith Street’ or ‘a chemical analysis spreadsheet of limestone’. This may result in you needing to split the data into several separate donations.
A donation may contain datasets that underpin publications. In these cases, NGDC is interested in holding the data rather than the associated paper.
Only one data access type (either open or restricted) can be applied to an entire donation. If your donation contains both open and restricted data, you will need to split your data and donate them separately, otherwise the open portion of your data will not be visible to our open web systems.
Bespoke portals to deliver your own organisation’s restricted donated data alongside NGDC openly available datasets can be built. Please contact the NGDC regarding commissioning such an activity.
Correct formatting containing no errors with commas or quotes which may prevent the file from being processed automatically
|Co-ordinates||Co–ordinates should be provided for all boreholes in British National Grid (m)|
|Key fields||All key fields must appear in each group but may contain null data. KEY fields are necessary to uniquely define the data|
|No orphan Records||All records should relate to a parent sample or hole|
|No duplicate records||No duplicate records should be present as this breaks unique identifier rules|
|Complete information||Important but not mandatory fields should be populated such as PROJ_CONT or PROJ_ID|
All Codes used should be present in ABBR
|Numerical values||Although text can be stored in all AGS fields, this is not always appropriate for values relating to units, so these should contain numbers with remarks in a remarks field if required|
|Lithostratigraphy Codes||Lithostratigraphy should be recorded as a BGS lexicon code in GEOL_BGS. It shouldn’t just be recorded as part of the GEOL_DESC text.|
Null means Null
|Where there is no value the field should be null, it should not be padded out with zeros as this may effect statistical analysis|
Data should normally be provided in a non-proprietary format (for example .csv rather than a Microsoft Excel spreadsheet).
The following formats are accepted by the NGDC:
|Data type||Preferred format||File extension|
|Geotechnical data||Association of Geotechnical and Geo-environmental Specialists (preferably version 3.1 or 4.0)||.ags|
|Geophysical data||Log ASCII Standard||.las|
|Sidescan sonar data||.xtf|
|Generic scientific data||Microsoft Excel files||.xls, .xlsx|
|Comma-separated value files||.csv|
|Data files (with readme file on software)||.dat|
|Tab delimited data file|
|Portable document format (PDF, PDF/A)|

Additional information for NERC-funded grant holders
NERC requires any data of long-term value created by NERC-funded activities to be deposited in a NERC Environmental Data Centre. NGDC is the designated repository for geoscientific data.

- Open Government Licence
The National Geoscience Data Centre (NGDC) actively encourages the deposit of openly available data via the Data Deposit Portal. The NGDC suggests some simple text can be added to contracts with clients, drillers or consultants, to request that data be deposited with open terms. Wording can be found on the Data Sharing Agreement page.
These data are available as deposited under the terms of the Open Government Licence by using the deposited data search and the GeoIndex. Please note some of our newer layers on the GeoIndex under ‘Boreholes’, Boreholes Other’ and ‘Deposited Data’.
Whilst NGDC prefer to hold open data with no access or use constraints, you can deposit restricted data for a limited embargo period giving justification on the ‘Data Access’ page/tab on the Data Deposit Portal.
Following the embargo date, NGDC will aim to automatically release the data in accordance with government open data policies. If you require a formal review, at which consideration is given to a future additional embargo period, please state and justify in the appropriate field. Note deposited data can be requested under the Freedom of Information (FOI) and Environmental Information Regulations (EIR) meaning the NGDC cannot respect all restriction requests.
Release of confidential information – site investigation and drilling information frequently asked questions.
Data Sharing Agreements
The National Geoscience Data Centre (NGDC) actively encourages the deposit of openly available data via the Data Deposit Portal. We have engaged with projects like the ASK Network (Accessing Subsurface Knowledge) and more recently through the Dig to Share Project to encourage the deposit of geotechnical data in AGS format.
The NGDC is collaborating with a number of organisations to create contracts and briefing notes for consultants carrying out ground investigation work to deposit AGS (Association of Geotechnical Specialists) data via the Portal.
Example agreements can be found below:
You can use the examples given to create new contracts, or the NGDC suggests some simple text can be added to contracts with drillers or consultants, to request that data is deposited with the NGDC in AGS format.

The NGDC also suggests to drillers and contractors to include some wording in standard contracts to ensure data is deposited with the NGDC.
