Study of Seaweeds sub species and their applications

Seaweeds are macrophytic algae, ubiquitously distributed along coasts from tropical to Polar Regions. They lack true roots, stem, leaves and generally grow in intertidal and sub-tidal regions of the sea. They belong to the Plantae kingdom, and being photosynthetic, constitute the basis of the food chain in aquatic ecosystems. Seaweeds are further classified as brown…

Analysis of Underwater Radiated Noise Based On Vessel Hull Vibrations

Pollution in the ocean is not just about the dumping of harmful chemical, physical orbiological substances into the sea, but also about the increased ambient noise. Ocean ambient noise results from both natural and anthropogenic(human-induced) acoustic sources. The latter are closely related to maritime shipping and seismic exploration by the oil/gas industry.

Identification of the Noise hotspots for Marine mammals in the Indian Ocean Region

Anthropogenic underwater noise is a form of pollution considered as a major threat for theconservation of marine wildlife, the impact of noise on marine mammals is a source ofconcern given that they heavily depend on acoustic signals to fulfil their vital functions.Their “acoustic habitat” appears nowadays altered by anthropogenic noise having bothdirect and indirect effects…

Mapping Snapping Shrimp Noise in the Indian Ocean Region

The snapping shrimp colonize warm littoral waters throughout the tropical and sub-tropical zones of the earth. The peak-to-peak source levels of a single shrimp snap have been recorded to be as high as 180 dB re 1μPa at 1m (louder than a jet at 140dB). Moreover, the combined snaps produced are essentially broadband signals and are observed…
