The underlying data that comprises the biodiversity values were collected between 1980 and 2023 using a range of survey methods. Further packages include overall and seasonal predictions of detected biodiversity incorporating the effects of shelf-sea fronts and internal waves.

These are the bird/mammal datasets, and the fish datasets. The bird/mammal datasets are comprised of at-sea animal observation surveys collated from several data sources between 1980 and 2022. Within this, the survey methodology varies from manual visual vessel surveys, such as observers posted on ferry routes, to aerial video surveys. Throughout the 40-year period some areas within the Exclusive Economic Zone (EEZ) have been extensively surveyed, whilst others have been visited only once or not at all. It is necessary to collate the entire 40-year period in order to achieve reasonable spatial coverage throughout the EEZ. The fish datasets used in this project are not observations as such, but are catch-per-unit-effort (CPUE) within the International Council for the Exploration of the Sea (ICES) Statistical Areas. These surveys have been conducted only in the North Sea, within which there has been relatively evenly-spaced sampling between 2010 and 2023. Combining the bird/mammal datasets with the fish dataset is a process that must therefore account for the very different ways in which these data have been collected so that they are weighted equally in the resulting biodiversity index.
