PINRO has conducted annual plankton research expeditions in the Barents Sea since 1952, typically running three surveys per year. The data includes mesoplankton and macroplankton samples collected with specific nets and methods to study community formation and trophicity. This long-term monitoring supports theoretical investigations into interannual dynamics related to Atlantic water advection.
Use Cases
- Model interannual plankton dynamics using the time-series data spanning over 70 years.
- Analyze species abundance for Calanus and Euphausiacea from samples collected with Juday and trawl-fastened nets.
- Investigate correlations between plankton data and abiotic factors recorded on sampling forms.
- Forecast fisheries food supply by using plankton community data as a prognostic predictor.
- Study vertical distribution patterns from data fished at standard depth layers (0-50m, 50-100m, etc.).
Strengths
- Time-series data collection initiated in 1952, providing over 70 years of temporal coverage.
- Surveys are conducted three times per year, capturing seasonal variation in plankton communities.
- Sampling employs standardized methods and gear (e.g., Juday net, specific trawl net) for consistency.
Limitations
- Specific sample counts, row numbers, and data volume are not disclosed.
- The raw description does not specify the spatial resolution or exact geographic coordinates of sampling stations.
- Data on file formats, licensing, and recent update frequency is unavailable.
