ABSTRACT: Understanding underwater soundscapes provide insights into the occurrence, temporal distribution and interaction of various geophonic, anthrophonic and biophonic sources. Soundscapes not only indicate coral reef health and quality, but also play a crucial role in the larval recruitment of fish, crustaceans, mollusks and corals. In the northern Indian Ocean, seasonally reversing monsoonal cycles play a significant role in shaping ocean life near mid-oceanic habitats. There have been very few studies characterizing coral reef soundscapes in this region, and most of these are limited in temporal resolution or do not cover the monsoon season. We conducted passive acoustic monitoring to understand the temporal variability in soundscapes across monsoon and non-monsoon months in the Lakshadweep islands, India. We identified the dominant sources and temporal drivers to the soundscape, and correlated acoustic bands to satellite-derived oceanographic variables. In this talk, I will discuss the status of this project and analysis plans.
