Abstract
Assessment of phytoplankton (diatom) dynamics was studied using NASA Ocean Biogeochemical Model (NOBM) from NASA Geospatial Interactive Online Visualization and analysis Infrastructure (Giovanni) system, from Jan 1998 to Dec 2015. It was carried out from Indian Ocean to Southern Ocean covering areas of various small seas (45–145°E, 35N–80°S). High and low abundance of diatoms were observed during two periods from September to November and March to May, respectively. The diatoms spatial distribution and richness were observed high between 40° and 60° South latitudes throughout the year. During December to February they increased between 40 to 70 degree south. In March to May between 40 to 45 degree south, during June to August near Gulf of Aden, Arabian Sea and in the months from September to November diatom increased in the southern ocean areas and dropped in other areas. This study reveals potential rich diatom areas with its seasons and results can be useful further in ecological studies
