Foraminiferal Assemblages from Recent Coastal Sediments of Chandipur, East Coast India

摘要

Background and Objective: The study area, being in close proximity of the estuarine and river mouth, is vulnerable to potential mixing and distribution of pollutants along with the sediment load into the ecologically sensitive tidal flat microhabitat. This study was conducted for investigating foraminiferal assemblages from recent coastal sediments of Chandipur, India. Materials and Methods: Total ten perforated and agglutinated foraminiferal species have been identified under scanning electron microscope. Their systematics and morphologies have been documented. Results: Dominant species are Ammonia beccarii , Ammonia tepida , Haynesina germanica and Quinqueloculina seminulum , mostly found in sand flats. Habitat and substrate preferences of various foraminiferal species have been established from the studied foraminiferal assemblages. Conclusion: Study shows great abundance of low diversity, epifaunal to infaunal foraminifera’s assemblages in Chandipur sand flats, muddy tidal flats and marshlands.
