1. Sewage nutrients do increase algal growth in the harbour. 2. This new tool has spurred many studies of acidification, and is being applied to other issues such as runaway algal growth and climate change. 3. A large area of its surface water is suffering from de-oxygenation due to algal growth. 4. Nitrates contribute to nutrient enrichment which encourages algal growth and blooms. 5. By contrast, said Boesch, the western bay has plenty, and added nitrogen would spur algal growth there. |
