Abstract:

The data describes net primary productivity data obtained from 14C-uptake standard 24h incubations during several cruises across the Southwest Pacific. The data spans 25 years (1993 - 2018) and includes measurements obtained in subantarctic and subtropical water masses and in the Subtropical Front that separates both. The dataset contains depth-resolved chlorophyll a concentration (mgChla/m³) and primary productivity measurements (mgC/m³/day) as well as areal chlorophyll a (mgChla/m²) and primary productivity (mgC/m²/day) calculated for the euphotic zone using trapezoidal integration. Environmental data including surface temperature, daily incident irradiance, attenuation coefficient and depth of the euphotic zone are provided when available.
