Overview • Surveying & Charting – In Antarctica – In the Ross Sea Region • Investigation of Ship-Bourne Tourism • Future Intentions • Recommendations

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

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

Investigation of Ship-Bourne Tourism New Sites visited • Cape Colbeck • New Harbour • Ross Ice Shelf

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
