GEBCO 측심 석사과정 (1년제)
명칭: GEBCO designed and managed Postgraduate Certificate in Ocean Bathymetry (PCOB) graduate certificate course in ocean mapping
교육수탁기관: 미국 New Hampshire대학교 Center for Coastal and Ocean Mapping/Joint Hydrographic Center
일본재단에서 장학금 (학비전액 및 소정의 체재비) 제공
졸업생 누계: 2004최초개설이래 32개국 60 PCOB course graduates working in their home country organizations, in academic institutes and in international industry. PCOB scholars are now active members of GEBCO subcommittees and working groups, are taking the lead in regional and capacity-building projects, and increasingly are in influential positions in their national organizations, and internationally, as a result of their Nippon Foundation / GEBCO training.
재학생 현황: 6 students currently studying at UNH. A new group of 6 students will start at UNH in August 2015
학과
- theoretical and practical aspects of ocean mapping
- 지구과학, 해양공학
교육방식
- 조별실습위주
- working visits to other ocean international organizations (for familiarization with the programs that the visited organization is engaged in, as well as some directed work under their supervision)
- opportunity to take part in a deep-ocean cruise to round out the students training
