Abstract

Abstract:

On the geophysics-imaged mud volcanoes over the northwest Dongsha Waters, a large number of deep-water benthic living organisms, fossils, and authigenic carbonate nodules were photographed by our newly developed portable underwater camera on 250-350 m deep seafloor. The organisms comprise abundant deep-water corals, glass sponge, sea anemone, sea lily, fish, shrimp, lobster and bivalve. The photographs further revealed that active methane leakage and mud volcanic activity in the Dongsha Islands area.

Key words: underwater camera, Dongsha Islands, mud volcanos, deep-water benthic living organisms, methane leakage
