Our skills

Developement of specialized tools

Analyzing larage datasets - including hydrological (temperature and salinity), physical (e.g., wave parameters), biogeochemical (e.g., oxygen, water color, nutrients) and other data - requires well-structured databases to ensure fast and efficient use. We develop our own databases to meet our R&D needs, as well as full suite of tools dedicated to data visualization, quality control, statistical analysis, and more. Our development methods prioritize the accessibility, interoperability, and portability of our tools.




QA/QC

Any data analysis can be biased or even inaccurate if poor-quality data (such as data from a faulty sensor) has not been filtered out beforehand. However given the volume of available data and the need to assess the challenges of distributing data in near real time, it is essential to have both automated and semi-automated data quality control procedures in place.

We develop and validate our own quality control procedures. We review and validate alerts in near real time so that we can provide higher-quality data to the scientific community and other policy and public stakeholders. Our validation methods ensure the traceability of any changes made.

Data management

We have built up expertise in vocabulary, harmonisation and duplicate detection, with a view to providing the community with high-quality metadata and data.

Data analysis

The data ingested into the database and quality-controlled by our team are subsequently catalogued, georeferenced, and post-processed (including the computation of derived parameters and mapping onto vertical and/or horizontal grids). They may also be stratified by geographical region. Leveraging our statistical analysis tools, these datasets are then used to develop new data-adjustment methods (i.e., real-time data correction) and to establish ocean indicators. This work contributes, among other objectives, to the assessment of the state of the ocean and enables us, for example, to contribute to the preparation of key reference reports such as Ocean State Report (OSR) published by Copernicus Marine Service.
