Data from the DICHOSO Project assesses spatio-temporal variability of marine biogeochemical variables in the waters of Deception Island, Antarctica. The dataset includes measurements of methane, pH, alkalinity, dissolved oxygen, nutrients, chlorophyll, trace metals, and vertical profiles from a multiparameter probe. It was collected by the SCIOPS organization from the Spanish base Gabriel de Castilla and last updated in March 2024.
Use Cases
- Model relationships between trace metals and other variables like pH and dissolved oxygen to study volcanic influence.
- Analyze vertical profiles of temperature, conductivity, and fluorescence to understand water column stratification and phytoplankton distribution.
- Assess spatio-temporal correlations between methane concentrations and total alkalinity to investigate biogeochemical processes.
- Use nutrient and chlorophyll data to study primary productivity dynamics in Port Foster.
Strengths
- Includes a multi-faceted suite of measurements covering over 10 key biogeochemical variables.
- Data is recent, collected and updated in 2024, reflecting current conditions.
Limitations
- Sample size and spatial coverage are limited to specific locations within Port Foster, Deception Island.
- The number of rows, columns, and temporal range within 2024 are unknown, limiting statistical assessment.
