ANALYSIS OF THE RELATIONSHIP BETWEEN MARINE FERTILITY AND PRIMARY PRODUCTIVITY IN THE BANDA SEA
The development of marine and fisheries sectors based on the Banda Sea is crucial for Maluku Province, as it is part of the Fisheries Management Area of the Republic of Indonesia (WPP-RI) 714 and has been designated as a National Fish Barn (LIN). To support this, information on the spatial and...

| Summary: | The development of marine and fisheries sectors based on the Banda Sea is crucial for Maluku
Province, as it is part of the Fisheries Management Area of the Republic of Indonesia (WPP-RI)
714 and has been designated as a National Fish Barn (LIN). To support this, information on the
spatial and temporal influence of sea parameters such as nitrate, phosphate, chlorophyll, dissolved
oxygen, and Ekman transport on primary productivity in the Banda Sea is essential. The data used
in this analysis includes reanalysis data from Marine Copernicus and CCMP for the period 1993
to 2020, covering various oceanographic parameters like nitrate, phosphate, chlorophyll, and
dissolved oxygen. High concentrations of nitrate and phosphate are generally found in coastal
areas and upwelling zones influenced by Ekman transport, indicating high fertility in the Banda
Sea waters. Based on Pearson correlation analysis, it was found that chlorophyll levels have a very
strong correlation (0.966) with primary productivity (PP), while dissolved oxygen also shows a
strong correlation (0.852) with PP. Phosphate exhibits a negative correlation (-0.144) with PP,
while nitrate (0.751) and wind (0.655) have positive correlations. These findings reveal the
complexity of interactions between environmental factors in influencing primary productivity in
the Banda Sea. According to the Minister of Environment Regulation No. 4 of 2011, the Banda
Sea is a fertile and nutrient-rich area, strongly supporting the development of the marine and
fisheries sectors in Maluku. |
