Spatial interpolation of Calanus finmarchicus and Calanus helgolandicus observations in the North Sea using the DIVAnd software tool.
The objective of this project is twofold:
- Create gridded maps of Calanus finmarchicus and Calanus helgolandicus abundances and
- Develop and apply a multivariate approach in the interpolatio method.
CPR stands for Continuous Plankton Recorder. It is an instrument, towed by volunteer merchant ships, designed to capture plankton samples. CPR datasets are unique in the sense that data have been acquired in a consistent way (same method) for more that 70 years.
The domain of interest ranges from 41.25°N to 67.0°N and from 20.5°W to 11.75°E.
In the instrument, plankton collected by continuously moving bands of filter silk is filtered and then the silk, stored in a cassette, is analysed in a laboratory.

- Each sample represents 10 nautical miles (< 20 km) of towing.
- The instrument towed at depth of about 5 -10 metres.
- Speed is up to 25 knots (46 km/h)

The formats are adopted for this project:
- netCDF, following the Climate and Forecast conventions for the metadata and attributes
- geoTIFF, more widely used in different scientific communities.
