Summer 2021 measurements of nitrate+nitrite, silicate, ammonium, and phosphate concentrations across 5 stations in Antarctic coastal waters. Data was collected during a January 20-27 research cruise by the AMD_KOPRI organization. This dataset captures nutrient distributions in the Marian Cove and Maxwell Bay.
Use Cases
- Model silicate and phosphate concentration gradients across the 5 sampling stations in Maxwell Bay.
- Analyze correlations between nitrate+nitrite and ammonium levels in Marian Cove surface waters.
- Map geospatial distribution of major inorganic nutrients during the Antarctic summer period.
Strengths
- Data collected during a focused 8-day summer cruise in January 2021.
- Measures 4 key nutrient types: nitrate+nitrite, silicate, ammonium, phosphate.
- Samples from 5 distinct geographic stations provide spatial coverage.
Limitations
- Limited temporal coverage from a single 8-day period in one year.
- Small spatial sample size of only 5 stations may not capture full bay variability.
- Unknown sample depth and replication details limit statistical analysis.
