The Vital Nutrients

Life in the Sea

Life in the sea around Australia seems to be rich. Yet in terms of marine biomass Australia is poor. For example some fifty other countries catch more fish than we do. Why are Australian waters less productive? In this programnm, we look at why some parts of the world’s seas are richer than others. We look at the marine carbon, nitrogen and phosphorus cycles, the biological carbon pump, how nutrients are distributed with depth and where and why upwellings occur. We also take a brief look at how humans are affecting the supply of nutrients with fertiliser run-off.
