Dr. Marc St-Onge Senior Research Scientist, Regional Geology, Department of Natural Resources

Thank you, Mr. Chair.

To begin with, I would like to thank all the members of the committee for inviting me here this afternoon to present a summary of the lecture that was given at the “Bacon and Eggheads Breakfast” at the beginning of May. I am very pleased to be here.

Given the time constraints this afternoon, I won't have time to present the full bacon and eggheads presentation that I presented at the start of May in the West Block. Rather, we'll focus on just a few key points that I hope will illustrate the importance and value of the new geological map of the Arctic for Canada and Canadians.

To start with, then, the new geological map of the Arctic, of which we have copies in the back for anyone interested in obtaining one, was published by the Geological Survey of Canada, part of the earth sciences sector of Natural Resources Canada, with the map presently available either as a hard-copy paper product for purchase or as a free download from the Natural Resources Canada government website.

Development of the new geological map of the Arctic was led by a Canadian research team based in Ottawa and Calgary, with the active and enthusiastic participation of scientists and technical staff from the geological surveys of Russia, the U.S., Norway, Denmark, Sweden, and Finland. Work on this project began in February 2006. The map was released to the public in November 2008.

If I could ask you to turn to page 30 of the handout, you'll see that the reason the new geological map of the Arctic and the related underlying database is so noteworthy is that the two together provide, for the first time, a complete, seamless, internally consistent digital documentation and interpretation of the circumpolar geology, with the map documenting, along with the related database, the distribution, the age, the composition, the association, the environment of formation, and the state of preservation of no less than 1,222 major map or rock units in the circumpolar Arctic. In other words, by combining various colours, various patterns, and various alphanumeric codes for different rock units or map units, this map provides information on those units all the way around the Pole, for all onshore areas and all offshore areas, with no gap, no break. In addition to all of this, the map also documents the location of linear and point features such as active faults or ancient faults, active volcanoes or dormant volcanoes, and other features that are listed on page 30.

In addition to documenting what is where from a geological point of view in the circumpolar Arctic, what else do this map and database do for us? If we turn to page 31, we see that the map and database, importantly, provide a global context for known mineral resources. In other words, a map user can go to the map and can go to the database, query about the geological context for a known mineral resource outside of Canada, and bring that information back to Canada in order to evaluate whether or not a similar geological context for similar mineral deposits might not be found in Canada.

Let's just look at one example. On page 31, again, we see zinc-lead deposits in central northern Norway, well known, with their characteristics written out on page 31. The question would be, is there a chance that similar deposits might be found in northern Canada? If we turn to page 32, we see that the answer is yes, and the similar yet unexplored geological context for that type of deposit corresponds to Bathurst Island, an island in the centre of the Canadian Arctic Archipelago. So that's just one example, with one commodity, of how information about known deposits elsewhere can be brought back to Canada to guide exploration in Canada.

The deck provides a similar example on the energy side of things, specifically natural gas, given that the new geological map of the Arctic and related database also provide a global context for any energy resources in the circumpolar Arctic. But I'll leave that for you to read, and I'll just address one last point in my presentation, and that is how the new geological map of the Arctic and related database can help constrain the geological origin of any given onshore or offshore feature. I thought for the presentation this afternoon that I'd use the example of the Lomonosov Ridge, thinking that might be of interest to some of you.

If you turn to page 36 of the deck, then, what you have there is the current plate tectonic geometry or configuration for the polar regions. There are three large tectonic plates: the Eurasian Plate, which carries northern Europe, western Russia, and central Russia; the North American Plate, which carries northern Canada, Alaska, and easternmost Russia; and the Greenlandic Plate, which carries Greenland.

The feature of interest, the Lomonosov Ridge, is highlighted with the dark blue line, separated from the Eurasian continent to the northeast by the Eurasian Basin, in much the same way as Greenland is separated from Norway and northern Europe by the North Atlantic. The present plate tectonic motions are shown with the red arrows, with the North American Plate and the Greenlandic Plate moving away from the Eurasian Plate at a rate of 1.4 to 2 centimetres every year. And you wonder why transatlantic travel costs more every year.

The way to constrain the geological origin of the Lomonosov Ridge, then, is to simply reverse the motion of the plates digitally and go back far enough in time, in a number of bite-size time increments. Looking at page 37, it is one step back in time to 23 million years ago. You will note that the North Atlantic is much narrower, Iceland has disappeared, the Eurasian Basin is narrower, and because of that, the Lomonosov Ridge has moved incrementally towards the Eurasian continent.

Turning to page 38, stepping back in time to 34 million years ago, the North Atlantic is much narrower again, the Eurasian Basin is narrower, and the Lomonosov Ridge is that much closer to the Eurasian continent.

On page 39, stepping back to 56 million years ago, the North Atlantic and Eurasian Basin are both much narrower, and this time Davis Strait, the body of water separating Greenland from northeastern Canada, is also starting to close, with Greenland moving back towards Canada.

And in a final step back in time, on page 40, to 61 million years ago, the North Atlantic is fully closed, the Eurasian Basin is fully closed, Davis Strait is fully closed, and the three tectonic plates—the Eurasian Plate, the North American Plate, and the Greenlandic Plate—are forming one large composite polar plate, with the Lomonosov Ridge tucked back, parked against the western rim of the Barents Sea continental shelf or European continental shelf, from whence it came.

In other words, the geological origin of the Lomonosov Ridge is as the outermost edge rim piece of the European continental shelf, faulted off, ripped off 61 million years ago.

The take-home message is that this was 61 million years ago. Ever since then, for a period of time that's longer than the Himalayas have been forming in Southeast Asia, the Lomonosov Ridge has been part of the North American Plate, moving away from northern Europe, moving away from western Russian, in tandem with the Canadian land mass at a rate of 1.4 to 2 centimetres a year, tracking 900 kilometres west to where we now find it beneath the North Pole.

The implications for Canada of having produced and published the geological map of the Arctic and related database are listed on pages 41 and 42. I could go through that or let you read it. I think possibly I'm out of time. I will conclude my comments with that.

Thank you very much, Mr. Chair.

Thank you very much for your attention.

Thank you very much, Mr. St-Onge.

I will now give the floor to Mr. Boerner.

12:15 p.m.

Dr. David Boerner Director General, Central and Northern Canada Branch, Geological Survey of Canada, Department of Natural Resources

I don't think at this point I have anything really to add, so we can probably just go to questions.

12:15 p.m.

Conservative

The Chair Conservative Maxime Bernier

Okay. So you can take maybe another five minutes if you wanted to explain other things to the members, and after that we'll go to the questions. I thought you were sharing your time.

12:15 p.m.

Senior Research Scientist, Regional Geology, Department of Natural Resources

Dr. Marc St-Onge

Excellent. Let me go through the implications, then. That will highlight the application of all of this.

Having produced this new geological map of the Arctic has done a number of things for Canada and the polar nations. The first thing is that this map now provides a seamless—no gaps, no breaks—geological coverage of the whole polar region, onshore and offshore, down to 60 degrees north. That's about 8% of the surface of the globe.

As I indicated, the new map provides a correlation tool for 1,222 map units from Greenland to Europe, from Russia to Alaska, and into northern Canada. In doing so, it provides the global context for mineral resources and energy resources that are known elsewhere. It allows us to bring that information back to bear in Canada to guide and help with new exploration work in Canada.

As I illustrated with the Lomonosov Ridge, the map can be used to resolve, document, sort out the geological origin of any feature onshore or offshore in the whole of the northern polar region. And finally, from a research and development management point of view, the new map also highlights where there might be gaps in knowledge or data or areas that need more work in Canada. The map and the underlying digital database are useful that way as well.

Great. Thank you.

We'll go to the members now.

Mr. Bagnell, you have seven minutes.

Liberal

Larry Bagnell Liberal Yukon, YT

Thank you for coming. It was your West Block presentation that encouraged me to have you come here.

Not to oversimplify the question, but based on all this, who owns the Lomonosov Ridge?

12:20 p.m.

Senior Research Scientist, Regional Geology, Department of Natural Resources

Dr. Marc St-Onge

Well, that's a good question. I guess I'll have to make a distinction between the information that is shown on this map and what, ultimately, the Commission on the Limits of the Continental Shelf will want to see.

The map documents, as I said, the onshore and offshore geology for the whole region, including the Lomonosov Ridge, and it does it using data that were available to us starting in February 2006, because that's when we started the compilation project.

The new data being acquired by Canada and the other polar nations in support of their submissions under the terms of UNCLOS.... For Canada, I believe that started in 2006, which is when we were working our compilation map, so that new data wasn't available to us. The important distinction is that the new data is of a resolution, a level of detail, that far surpasses what we can show at this scale, but that's the level of detail that UNCLOS and the commission will be requiring in order to make their judgments.

So I hesitate to tell you who owns the Lomonosov Ridge, because we're talking about two different data sets.

12:20 p.m.

Liberal

Larry Bagnell Liberal Yukon, YT

I was worried about that.

What does UNCLOS require, though—what specific type of information—to make a claim?

12:20 p.m.

Senior Research Scientist, Regional Geology, Department of Natural Resources

Dr. Marc St-Onge

UNCLOS requires principally two data types: detailed information on bathymetry, which is the depth to the ocean floor, and detailed seismic surveys. I illustrate both in the deck here, because we made use of what was available to us at the start of 2006 in compiling this map, including bathymetry and seismic data. The difference with UNCLOS is that what they require is much more detailed information. Specifically, the requirement by UNCLOS is transects for bathymetry and for seismic data that are spaced 60 nautical miles apart. I believe Canada is doing it every 50 nautical miles, to be on the safe side. That's good. It's detailed information that will eventually be made public, but wasn't available for the compilation of this map.

12:20 p.m.

Liberal

Larry Bagnell Liberal Yukon, YT

If there were a spot on the ridge that was equidistant from Canada and Russia or Greenland and Russia, what information would decide who owned that part of the ridge?

12:20 p.m.

Senior Research Scientist, Regional Geology, Department of Natural Resources

Dr. Marc St-Onge

In any submission for an extension of the continental shelf, and the Lomonosov Ridge would be one example, the requirement is demonstrated with the detailed bathymetry and seismic data that there is an extension; that the ridge, in this case, is attached to one shelf or the other. If one country or the other can prove that, then I believe the limits to the extension work out to 350 nautical miles—so there is a limit to how far you can take things. But first you have to demonstrate that the ridge, in this example, is attached to either the Canadian-Greenlandic side or to the Russian side at the far end.

12:20 p.m.

Liberal

Larry Bagnell Liberal Yukon, YT

Is it connection by depth or by geological feature?

12:20 p.m.

Senior Research Scientist, Regional Geology, Department of Natural Resources

Dr. Marc St-Onge

It's both. That's the nice thing about UNCLOS, that it's geology-based; there has to be a geological connection. In other words, the rocks that form the Lomonosov Ridge, in this case, have to have, from the Canadian perspective, we would hope, a link to mainland Canada's geology. Likewise, bathymetrically you'd like to see a bridge, an apron, between mainland Canada or the Canadian contiguous continental shelf and the Lomonosov Ridge itself.

12:25 p.m.

Liberal

Larry Bagnell Liberal Yukon, YT

Do sediments have any part in this or in anything related to UNCLOS?

12:25 p.m.

Senior Research Scientist, Regional Geology, Department of Natural Resources

Dr. Marc St-Onge

Absolutely they do, because the thickness of sediments that rest on the bedrock, let's say—the core of the ridge—helps in establishing that bathymetric tie between the ridge and mainland Canada, for example.

12:25 p.m.

Liberal

Larry Bagnell Liberal Yukon, YT

Can you make any comment on the volume and locations of methyl hydrates, of frozen methane in the Arctic?

12:25 p.m.

Senior Research Scientist, Regional Geology, Department of Natural Resources

Dr. Marc St-Onge

Yes. Canada is certainly well endowed in gas hydrates, which is basically methane frozen in ice crystals, both because the extensive permafrost that characterizes northern Canada—and the bulk of Canada's north is above 60 degrees north—is permafrost hosting gas hydrates inland, and also, if the water depth is sufficient, because pressures and temperatures will be such that gas hydrates will also exist at the bottom of a deep column of cold water. So again, on that front, Canada is well served by Mother Nature.

12:25 p.m.

Liberal

Larry Bagnell Liberal Yukon, YT

There's a suggestion that there are more of those than of all the other hydrocarbons in the world. Is that...?

12:25 p.m.

Senior Research Scientist, Regional Geology, Department of Natural Resources

Dr. Marc St-Onge

I don't know the specifics of that.

David, do you?

12:25 p.m.

Director General, Central and Northern Canada Branch, Geological Survey of Canada, Department of Natural Resources

Dr. David Boerner

Yes, that's one of the estimates. It is based on fairly limited data; it's hard to know the exact extent of these things. But if you take what we know and project it out, that has absolutely been one of the calculations people have made.

12:25 p.m.

Liberal

Larry Bagnell Liberal Yukon, YT

In the meeting before this, we had witnesses from the north say that they wanted to continue the geoscience program for years to come, because a lot of Nunavut and the Northwest Territories in particular has not been mapped by the geoscience programming. I'm wondering how you can have a comprehensive map that has everything, if these people are saying there's a lot that hasn't been done.

12:25 p.m.

Senior Research Scientist, Regional Geology, Department of Natural Resources

Dr. Marc St-Onge

Both can co-exist. The reason our partners suggest that, and we agree with it, refers to the comment I made about the new compilation and underlying database being a useful tool for management to decide where to go next and what area needs more work. Although the map is all coloured, the level of detail in different parts or segments of the map isn't uniform, and certainly when one looks at the database, it's not populated as densely in some areas as in others.

We've used the information and the data available to arrive at an internally consistent picture and interpretation, but that's not to say that there aren't areas—there are many of them in northern Canada—that absolutely need more work to bring things up to a more international standard.

Claude Bachand Bloc Saint-Jean, QC

Thank you, Mr. Chair.

Welcome. I would like to start by congratulating you. You live up to your reputation in the area of clear, understandable and accurate maps. I am very impressed by your work. I did not think it was so advanced.

The material you presented seems extremely interesting, and I would like to know more about it. Here we are limited to five or six minutes for our questions, and I will not be able to get in-depth understanding. At some point, I would like you to call either my office or Mr. Paillé's office, or someone else's office to give us a more in-depth briefing.

I thought I had read recently that the Canadian claim to the continental shelf is quite large and extends beyond the archipelago. Somewhere it even said that we could pursue the studies beyond the North Pole.

Did I read that correctly, or is it because I have the impression that the Canadian continental shelf goes on and on indefinitely?
