Concentrations of individual sterols and n-alkanes were measured in the seawater of Kongsfjorden, Svalbard. The dataset was collected by the Korea Polar Research Institute (AMD_KOPRI) during April 2018, focusing on a specific Arctic fjord environment.
Use Cases
- Analyze sterol concentration patterns to trace marine vs. terrestrial organic matter inputs.
- Investigate n-alkane concentration distributions as indicators of petroleum contamination or biogenic sources.
- Correlate compound concentrations with spatial or temporal sampling points within the fjord.
- Compare the measured sterol profile to known biological sources like phytoplankton or zooplankton.
Strengths
- Data is specific to a single, well-defined Arctic fjord (Kongsfjorden, Svalbard).
- Focuses on two specific classes of organic compounds (sterols and n-alkanes).
- Collection date is precisely recorded (April 2018).
Limitations
- The total number of samples (rows) and measured compounds (columns) is unknown.
- Data is limited to a single month (April 2018), providing a seasonal snapshot rather than long-term trends.
- Geographic coverage is restricted to one fjord system in Svalbard.
