Demonstration Test Catchments: Data sharing and archival - WQ0219

Description
SEE http://www.environmentdata.org/dtc-archive-project for the DTC data archive generated by this project

***********************************************************************************************************************************

Defra’s Demonstration Test Catchment (DTC) project examines aspects of three test catchments (the Eden [Cumbria], Hampshire Avon and Wensum [Norfolk]), in order to investigate innovative solutions to the long standing water quality problem of diffuse pollution. A major component of the DTC approach is intensive monitoring of the environment in order better to understand the origin and nature of stressors, a key issue in the UK’s successful compliance with the Water Framework Directive. This project, the provision of a data archive for the DTCs, provides a key extra element to the DTCs.
A small data archive consortium of the Freshwater Biological Association (FBA), a leader in environmental data archiving, and King’s College London, a major developer of processes for handling and using electronic data, has the crucial task of receiving data gathered by three larger consortia (one for each of the three test catchments) and storing it in a dedicated archive in such a way that it is secure for the long term and easily accessible by consortia members, the people living in the three catchments, decision and policy makers. Tools, using leading edge technologies, will be developed to enable interrogation of the data to be achieved in an enjoyable, clear and efficient way and will be as accessible as possible.

In order to achieve this aim, it will be necessary to carry out much innovative work in order to develop the data archive into a format in which users can add or access information easily. The types of data are varied, including water chemistry, hydrological information, weather records, ecological data and ‘soft data’ (photographic and video images, subjective assessments, etc.). An effective archive will link interrelated components of this diverse data archive together so that users will be able to find relevant information in response to search queries. The task of this project, in addition to accepting and storing data, will be to make its use as intuitive and valuable as possible.

The data archive project team will talk to the researchers who will provide the data, and to potential users, including farmers and other land owners, in order to understand the uses to which the data may be put. Following this, the data archive team will develop ontologies, which use words and phrases (‘vocabularies’) specific to the types of use anticipated in order to allow users to find data easily; this will be combined with an intuitive approach to querying the data and a clear understanding of the formats in which users will want data to be made available. The entire process will be web-based, and will use web portals designed specifically to facilitate input and output of the data. Data provision will be connected, where appropriate, with supporting information to enable stakeholders better to understand its meaning and relevance to their needs.

Forums, newsletters and other communication activities will be organised for researchers and the stakeholders to demonstrate the new techniques and to raise awareness of the work being done, the results and the implications for ways in which water quality can be improved in future. Care will be taken to complement the activities of each of the consortia to maximise the cost effectiveness of these knowledge transfer activities, recognising that these must be of a high standard and can be very consumptive of resources. The FBA’s existing connections to farmers and their organisations, those interested in the natural history of water bodies and their surroundings, environmental charities, the water industry and regulators will be used to maximise the spread of knowledge from the project and to raise the profile of water quality.

Following the completion of the initial development and of the DTC projects, steps will be taken to ensure the long term viability of the data archive as a mechanism for storing and accessing valuable data on rivers catchments and water quality.
Objective
7. (b) Objectives

The general objective of this work is to provide a mechanism for storing, collating and accessing data from the Demonstration Test Catchments (DTCs) in a way that is usable for data providers, specialist data users and other stakeholders in the three catchments and elsewhere.

The proposed programme of work will be broken down into eleven Work Packages (WPs: described in 7.(c)), each of which is associated with a set of time-bound objectives that together will fulfil the general objective. This breakdown will make the work easier to manage and progress easier to monitor. The specific objectives are as follows, the numbers matching those of the WPs.

Note 1: The dates indicated assume a project start date of 1 Jan 2011.

Note 2: Because of the iterative nature of our approach, project deliverables will be made available in phased versions, so it is important to understand to what the dates below refer.

For documents (e.g. the data model), the date refers to the publication of the first complete version, which will be regarded as quasi-definitive for the project. This may however be subject to further updates during the project in the light of changing circumstances, in which case a final version will be released at the end of the project as part of the documentation set.

For software, the date refers to the release of the first, complete, tested beta version of the code in question, for final, formal evaluation by stakeholders. Earlier, partial, releases will be made available in accordance with the agile development methodology followed by the project.
