The 3d Seismic Survey Of East Godavari Mangrove Area

The 3D seismic survey in East Godavari mangrove area has short-term effects on the environment. The surveyed area includes the main six reserved mangrove patches in East coast of India and the process of lying of geophones cables and shoot hole drilling for 3D seismic exploration may lead to the destruction of habitat through clearing the vegetation. Primary sources of disturbances associated with exploration include equipment transportation inside the mangrove, vehicle traffic, shot hole drilling activities, and underground blasting. Seismic exploration survey has the potential to affect wildlife either by increasing noise and human activity around them, or seismic shooting process. The seismic activities can even lead to long-term habitat alteration. Though the exploration activities is often a short term process, extending over a few months, the footprint of exploration activities especially in the high wildlife sensitive area can be quite large (Jorgenson et al. 2010). Seismic ex ploration can alter plant community structure, directly affecting fauna of that area on a long-term basis (Jorgenson et al. 2010). There is evidence to suggest wildlife may react to seismic activity with elevated metabolic rates (Bradshaw et al. 1998), and the cumulative effects of repeated disturbance of individuals may affect population reproductive rates if exploration is widespread (Bradshaw et al. 1998). Extensive studies are conduced to estimate the impact of seismic activities on marine
