Algae floods Arabian Sea
A green algae growing in the Arabian Sea is threatening fisheries in the region. A report by Columbia University's Lamont-Doherty Earth Observatory says green
Noctiluca scintillans has been spreading over the last decade. It is a plankton that survives in low-oxygen waters and a growing "dead zone" in the Arabian Sea has allowed it to dominate the region. Discharge of nutrientrich sewage from coastal cities is expanding the dead zone. Fisheries help sustain 120 million people living along the shores of Oman, India and Pakistan.
