Fisheries and Oceans Canada provides baseline data on dinoflagellate communities, including abundance, richness, and diversity, from four Arctic ports. The dataset was collected via plankton net sampling in August across multiple years between 2007 and 2019. It includes environmental variables measured with a CTD and Secchi disk.
Use Cases
- Analyze dinoflagellate abundance and richness across ports like Churchill and Iqaluit to establish baseline biodiversity levels.
- Verify the presence of potential non-indigenous species using taxonomic data from the collected samples.
- Correlate environmental variables like Secchi disk measurements with dinoflagellate community diversity.
- Compare temporal changes in communities using data from repeated sampling years, such as 2007 and 2015 in Churchill.
Strengths
- Data collected from four distinct Canadian Arctic ports: Churchill (MB), Deception Bay (QC), Iqaluit (NU), and Milne Inlet (NU).
- Sampling spans multiple years from 2007 to 2019, providing temporal context.
- Includes derived metrics for dinoflagellate abundance, richness, and diversity.
- Associated environmental variables were measured using a CTD and Secchi disk.
Limitations
- Sample collection is limited to the month of August, missing seasonal variation.
- Geographic coverage is restricted to four specific port locations in the Arctic.
- The sample size and number of rows are not specified in the input.
