Calcareous Nannoplankton (marine algae) Analysis in Subsurface Sediments of Andaman Sea

Abstract

Andaman Sea in the Indo-Pacific Warm Pool (IPWP) is influenced by Indo-Australia monsoon winds. Marine sediment cores in this area, BS36 (06°55’50.8”N; 96°07’28.51”E; ; Water depth 1147.1 meters) were acquired by Geomarin III research vessel andanalysed its morphology for nannoplankton occurences. Results from qualitative identification on marine sediment core in Andaman Sea obtained 11 genus of nannoplankton marine algae in this area. Dominated genus discovered in this site is Gephyrocapsa, Emiliania, and Helicosphaera. Although this research is qualitative and preliminary study phase; however, this reference of modern nannoplankton taxonomy and features using Scanning Electron Microscope (SEM) would enhance marine algae biodiversity along Andaman Sea of Indonesian waters
