MALINA Expedition 2009 Arctic Carbon and Plankton Data

Seven shelf-basin transects were sampled during the summer 2009 MALINA oceanographic campaign in the Mackenzie River estuary and Beaufort Sea. The dataset contains measurements of physical, chemical, and biological variables including temperature, salinity, nutrients, chlorophyll a, and plankton abundance and taxonomy. It was produced by the OB_DAAC organization and published by Massicotte et al. in 2021.

Use Cases

• Analyzing meridional gradients in carbon stocks and fluxes across seven shelf-basin transects.
• Correlating phytoplankton and zooplankton taxonomy data with concurrent measurements of nutrients and chlorophyll a concentration.
• Investigating the relationship between physical variables (temperature, absolute salinity) and biological communities in an Arctic estuary.
• Studying carbon flux processes controlled by measured variables like irradiance and bacterial abundance.

Strengths

• Dataset covers a wide suite of integrated physical, chemical, and biological variables measured concurrently.
• Sampling design captured a spatial gradient across seven distinct transects from estuary to open ocean.
• Data is associated with a peer-reviewed publication (Massicotte et al., 2021) providing scientific context.

Limitations

• Exact row count, column names, and dataset size are not provided on any platform, limiting precise technical assessment.
• Conflicting license information: nasa_earthdata lists 'other-license-specified' in one entry and 'None' in another, while datagov lists 'other-license-specified'.
