Adam Greenland National Hydrographer 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 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 Surveying & Charting in the Ross Sea Region 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
