Hydrography, Underwater Archaeology & Collaboration = Success‎!

Although this is not their primary role and raison d’être, hydrographic surveyors are no strangers to locating shipwrecks in the due course of conducting surveys for safety and efficiency of navigation, nautical charting and seabed mapping.  Likewise, Archaeologists are no strangers to imaging the seabed when conducting surveys to locate artefacts. Indeed, each use similar tools for different mandates and objectives and so it would be somewhat more than just coincidence the two disciplines might benefit one another through collaborative actions, particularly where the proposed survey area was extensive and complex logistical challenges were to be overcome.

Such collaboration, between Parks Canada, Underwater Archaeology Service (UAS) and Fisheries and Oceans Canada, Science – Canadian Hydrographic Service (CHS) was conceived, developed and executed over the past decade, resulting in over 1500 square kilometres of modern hydrographic surveys and seabed mapping which ultimately lead to the discovery of HMS Erebus in September, 2014.  The context of past and modern expeditions to locate the wrecks of HMS Erebus and HMS Terror will be presented along with the role of hydrographic surveying in its relevance to underwater archaeology.


Andrew Leyzack, C.L.S.

A graduate of Humber College’s Hydrographic and Land Survey Technologist programs, Andrew has been surveying for over 25 years, with varied experience in topographic, cadastral, offshore/industrial and hydrographic surveys for nautical charting.  He is a Commissioned Canada Lands Surveyor, working as an Engineering Project Supervisor with the Canadian Hydrographic Service (CHS), Central and Arctic Region (Federal Department of Fisheries and Oceans Canada). He was involved with developing and executing the CHS’s collaboration with Parks Canada on the “Search for Franklin” from 2006 to 2012. He currently leads a team involved with data management.  He is past president of the Canadian Hydrographic Association and past chair of FIG Commission 4.





Ryan Harris

Ryan Harris,  a senior underwater archaeologist with Parks Canada, was born in Calgary, Alberta. He completed his Bachelor’s degree in Anthropology at the University of Toronto then studied at East Carolina University, in Greenville North Carolina, where he graduated with his Masters in Maritime History and Nautical Archaeology. Working as an underwater archaeologist with Parks Canada since 1998, he has participated in more than 60 underwater archaeology projects across the country. In July 2010, Ryan led the archaeology work that located the wreck of HMS Investigator(1853) off the shores of Aulavik National Park in Mercy Bay, NWT. Ryan also served as the lead archaeologist for Parks Canada’s search for the lost vessels of the 1845 Sir John Franklin Expedition, which after six field seasons beginning in 2008, culminated in the discovery of HMS Erebusin September 2014. Presently, he continues to direct site investigations on the Investigator and Erebus wreck sites, and will do the same with the wreck of HMS Terror, recently discovered in 2016. His professional research interests include historic ship architecture, remote sensing applications in underwater archaeology, and the maritime archaeology of 19th-Century British polar exploration. In 2015, Ryan was an inaugural recipient of the Governor General’s Polar Medal.

Denis Hains

Mr. Denis Hains is the Director General, Canadian Hydrographic Service (CHS). The position also carries the title of Hydrographer General of Canada.

Mr. Hains began his career at CHS in the Québec Regional office. He eventually went on to become the CHS Director for Québec Region.

He worked at Natural Resources Canada (NRCan) as Director, Canadian Geodetic Survey, before returning to the CHS to serve as acting Director General and Dominion Hydrographer in early 2000s.

This assignment was followed by the Director General, Integrated Business Management Services position at the Canadian Coast Guard. He then returned to NRCan, as Director, Earth Observation and GeoSolution Division, and then as Director, Canadian Geodetic Survey.  This is where he stayed until he accepted his most recent post of Director General, CHS in early 2014.

Mr. Hains holds a Bachelor of Science Degree in Geodesy from Laval University in Québec City, Canada and he is a member of the Québec Land Surveyor Corporation as well as the Canadian Hydrographic Association. He is the Co-Chair of the US Canada Hydrographic Commission and he was the 2016 Chair of the Arctic Regional Hydrographic Commission of the International Hydrographic Organization.
