Surveying & Charting in Antarctica

  • Majority of Antarctica remains unsurveyed or requires modern re-

survey

  • Less than 1% of sea area within 200m contour is adequately

surveyed to meet the needs of contemporary shipping

  • Greatest effort to-date focused on Antarctic Peninsula MSR
  • NZ responsible for the Ross Sea Region
  • LINZ is responsible for authoritative hydrographic information,

primarily for safety-of-navigation

  • IHO HCA promotes, facilitates, stimulates & encourages

hydrographic activities in Antarctica

Surveying & Charting in the Ross Sea Region

  • New Zealand Survey Activities

– LINZ contracted safety-of-navigation surveys in 2001 & 2004 (Cape Adare to Cape Hallett) – Opportunistic surveys during 2006 & 2008 (Scott Island & Balleny Islands)

Surveying & Charting in the Ross Sea Region

  • New Zealand Survey Activities

– 8 new charts published in last 6 years – But, still limited coverage and significant unsurveyed areas

Surveying & Charting in the Ross Sea Region

  • Data received by LINZ

– 2004 R/V Palmer Scientific cruise resulting in 2 new charts for Ross Island (INT 9001 & 9002) – GNS database of 116 surveys spanning 3 decades. Data to be assessed for charting programme

Investigation of Ship-Bourne Tourism

  • Analysis of IAATO Overview of Antarctic Tourism Reports from 2003

to 2008

  • Tourism fluctuates annually
  • A small number of tourist vessels
  • Most popular sites: Cape Adare & Cape Bird (ASPA)
  • New sites: Cape Colbeck, Ross Ice Shelf, New Harbour

Future Intentions

  • Further investigation & analysis required (science & Govt vessels)
  • Highlight survey & charting needs
  • LINZ to develop prioritised survey plan for Ross Sea Region, guided

by HSPWG & present at next IHO HCA meeting

  • Consider all options
  • Collaborative approach, LINZ Ross Sea Region Strategy 2003-2012
  • NZ will continue to support, promote & contribute to the work of the

IHO HCA

Recommendations

  • The Antarctic Treaty Parties should advise all tourist vessels

intending to operate in the Antarctic Treaty area to be aware of the limitations of the adequacy of charts for the region

  • The Parties should contribute to the improvement of charting

information
