Impact of 'Chitra' oil spill on tidal pool macrobenthic communities of a tropical rocky shore (Mumbai, India)
Sukumaran, S.; Mulik, J.; Rokade, M.A.; Kamble, A. (Coastal and Estuarine Research Federation, 2014)A collision between the ships MSC Chitra and MV Khalijia 3 in the mouth region of Mumbai Harbour led to a leakage of around 800 t of fuel oil in August 2010, affecting the rocky intertidal region of Colaba. To evaluate the ... -
Macrobenthos in anthropogenically influenced zones of a coralline marine protected area in the Gulf of Kachchh, India
