NAME OF DIVISION

:

Oceanography Division

BRIEF INTRODUCTION

:

Deals with the ocean extending from the shallow estuarine areas to the deeper locations of the ocean for survey, monitoring, digital mapping and management of natural resources in the areas of environment, coastal, marine zone, infrastructure planning, etc. (more)

OBJECTIVES

:

Application of space and satellite based remote sensing technology in coastal, offshore and open sea for exploration and exploitation of available resources therein.

MAJOR FUNCTIONS

:

·         Monitoring and Mapping of Morphological Changes of Coastal Area, Bangladesh
