LE BULLETIN DE L’UNION GÉOPHYSIQUE CANADIENNE
President’s Column
In this issue, I would like to present CGU members with a brief report on the recent CGC (Canadian Geoscience Council) meetings in Calgary, which took place on May 29 and 30, 2004, and which I attended in place of CGU President Phil Marsh. These were the CGC Council of Presidents Meeting, the 112th Annual Meeting of the CGC, and the CGC Annual Business Meeting.
The focus of the Council of Presidents Meeting was on geoscience education and outreach in Canada. Various issues were discussed, such as outreach activities currently underway in CGC member organizations, future collaboration, demographic issues in geoscience, and areas of improvement in outreach activities.
Here are some key points summarizing the meetings:
• The meetings were attended by representatives of many of the member organizations of the CGC, i.e., CAG, CGS, GAC, GSC, CIM, MAC, CSPG, CSEG, CGU, PDAC, NRCAN, CANQUA.
• The CGC is aware of the concerns of the CGU (and other organizations) about the current usefulness of the CGC. The CGC is striving to become an umbrella organization which is truly representative of all the geoscience communities in Canada, and genuinely hopes that the CGU and other organizations will be supportive of this.
• The CGC is developing an outreach initiative,
through CGEN (the Canadian Geoscience
Education Network), and encourages each
member organization to work together with the
CGC/CGEN on outreach, perhaps by appointing
an “Outreach and Geoscience Education
Director” on the organization’s executive
committee. Outreach is important to the CGC
because of statistics showing the gradual decline
of geoscience support in Canada. Those
interested should contact Allan Morgan
([email protected]).
Some member
organizations already do a lot of outreach (e.g.,
the MAC, GAC, GSC, CSPG, CSEG, CIM,
PDAC).
• A presentation on the IODP (Integrated Ocean Drilling Program) was given by Kathy Gillis, Canadian IODP Science Director, University of Victoria. IODP is a multi-national program supported mainly by the US, Japan, and ECORD (a consortium of European countries). Canada’s participation is currently as a part of ECORD. If funds cannot be raised in the future, Canada may have to drop out of IODP because of the high cost of membership (about a million dollars per year).

Other CNC-IAHS activities
At the IUGG in Sapporo, Japan, July 2003 a meeting was held to discuss the future of ICASVR (International Commission on Atmosphere-SoilVegetation Relationships) which had become moribund. It was decided to continue the commission under a new name - International Commission on the Coupled Land Atmosphere System (ICCLAS) - and to propose a symposium for the Brazil meeting in 2005. Canada supported this revival of a Commission for such an important subject.
CNC-IAHS deliberated on various decisions for Canada relating to the International Hydrology Prize. Canada has been active in the IAHS PUB Decade, organizing a meeting in Yellowknife, NWT in March (Chris Spence, Al Pietroniro, John Pomeroy) which considered cold regions aspects of PUB and organising a PUB session at CGU/AGU Montreal (Pomeroy).
The PUB website is http://cee.uiuc.edu/research/pub/default.asp
CNC-IAHS is encouraging Canadians to submit abstracts and papers to the 7th IAHS Scientific Assembly to be held in Foz de Iguassu, Brazil, April 24-30, 2005, abstracts for symposia are due at the end of May, 2004.

Northern Research Basins
Committee Chair: Dr. Philip Marsh, (Chief Delegate), NWRI, 11 Innovation Blvd. Saskatoon, SK S7N 3H5, [email protected]
8
Deputy-Chief Delegate: Dave Milburn, DIAND, Yellowknife
Past Chief Delegate: Garry Thorne, AECL Research, Pinawa, Manitoba
Mandate and Objectives The role of the NRB working group is to
encourage research and exchange ideas and information on northern research basins, in which snow, ice and frozen ground have a major influence on the hydrological regime. The NRB Working Group normally meets every two years with the meeting consisting of two parts; a symposium at which formal papers are presented; and, a workshop at which special hydrological research topics or issues of international interest are considered and task force reports presented. As part of the International Hydrological Program, the Northern Research Basins Working Group has held regular meetings since 1975 and full membership is currently open to all countries with land territories lying north of the Arctic Circle. In 1998, the Canadian NRB working group became a sub-committee of the Canadian Geophysical Union-Hydrology Section.
As outlined in the NRB Mandate and the Canadian NRB Terms of Reference the Canadian participation in the NRB is limited to 10 delegates appointed by the Canadian Chief Delegate to represent Canadian interest in the hydrology of northern areas. The Canadian Chief Delegate at the 12th and 13th meetings was Garry Thorne. Philip Marsh has since been appointed as the Chief Delegate and David Milburn as the Deputy Chief Delegate for the next 2 meetings (the 14th and 15th NRB Workshops).
Progress on Issues and Objectives The CGU-HS Northern Research Basins
Committee participated in the 14th NRB Symposium and Workshop held in Kangerlussuaq/Sdr. Stromfjord, Greenland from August 25 to 29, 2003. There were 39 attendees, including 10 Canadians, at the 14th meeting, representing seven of the eight member countries which include Canada, Denmark/Greenland, Finland, Iceland, Norway, Russia, Sweden and the USA. The 26 papers in the proceedings, and 33 presented at the meeting, covered a wide range of topics, with the major emphasis on snow, ice and permafrost. Many of the papers also addressed the symposium theme of "The role of high latitudes in global water blance and element budgets”. Reports were received from the an NRB Task Force led by Doug Kane of USA, which is focused on comparison of basin water balance from a range of circumpolar environments. The proceedings of the meeting have been published, and papers have been submitted for consideration for publication in a special issue of the journal, Nordic Hydrology.
Other NRB business and issues:
a) The NRB working group will be constructing and maintaining a Canadian Northern Research Basins website (expected to be www.canadianNRB.com). Work has begun on acquiring background information.
b) Once completed this web page will be linked to the CGU-HS web site, that will provide current Canadian and other information regarding NRB activities.
c) The collection of NRB Proceedings, and special Journal issues, has been updated to include all proceedings. This collection is housed in the library at the National Hydrology Research Centre in Saskatoon.
Future events
Planning has started for the 15th International
Northern Research Basins Working Group Meeting. This
meeting will be held in Sweden, during August 2005.
More
details
are
available
at
http://aqua.tvrl.lth.se/NRB_2005.html. As in past years,
each NRB country is limited to a maximum of 10
delegates. Canadian Delegates will be by invitation of the
Canadian NRB Committee, and approved by the CGU-HS
Executive. Other Canadians may apply to the conference
organizers, and will be accepted depending on space, with
preference provided the official Canadian Delegates.
Glaciers and Environment Committee
Chair: Prof. D. Scott Munro, Department of Geography, University of Toronto at Mississauga, Mississauga, ON, L5L 1C6 CANADA, [email protected]
Vice-Chair: Michael N. Demuth, P. Eng., Geological Survey of Canada;
Advisory Members: Prof. Martin J. Sharp, University of Alberta Dr. Roy M. Koerner, Geological Survey of Canada Jeffrey Schmok, Golder Associates Ltd.
Mandate and Objectives A. Assist the CGU and its executive in promoting
glaciological research that is relevant to hydrological and environmental problems. B. Provide CGU members with information about glaciological research activity, as well as identify opportunities for collaboration among individuals and groups. C. Provide CGU members with information about the scope and extent of glaciological data, and promote efforts to improve accessibility to such data.
9
D. Influence research development by establishing lines of communication with other working groups in snow and ice, such as the Cryospheric System (CRYSYS) to monitor global change in Canada and identify personnel training opportunities.
E. Identify and promote opportunities for educating other members of the scientific community and the general public about glaciers and their role in the environment.
Meetings and Activities a. Michael Demuth and Roy Koerner continue to build
the National Glaciology Program (NGP) in the Geological Survey of Canada (GSC), supported by Natural Resources Canada, Environment Canada and University partners, consolidating research in Arctic and Western Canada. b. A book entitled Peyto Glacier: One Century of Science, M.N. Demuth, D.S. Munro and G.J. Young (eds.), is in the final stages of copy editing. c. Michael Demuth, continues as Canadian Correspondent to the International Glaciological Society, and Canadian National Representative to the International Commission on Snow and Ice. d. Scott Munro has recently completed A revised Canadian perspective: progress in glacier hydrology, a sequel to an earlier review which appeared in Hydrological Processes 14: 1627-1640. e. Scott Munro recently attended the Automatic Weather Station (AWS) Workshop, Pontresina, Switzerland, March 2004, to describe the Western Canada glaciers AWS effort to the international glaciology community and to gain insights on improving the Canadian effort.
Progress on Issues and Objectives The NGP work, in partnership with others, is
central to the first objective of this committee where progress occurs through continued development of the AWS program at the Peyto, the Place and, most recently, the Ram River Glaciers. Toward the second objective, Peyto Glacier: One Century of Science describes the research context for the CGU and others, while A revised Canadian perspective: progress in glacier hydrology reports Canadian research achievements to the world glaciological community. Improvements to the NGP program require new sites in Yukon and British Columbia, and better data management, key points in addressing our third objective. The NGP consolidation effort is essential to our fourth objective: linking research among universities and agencies (e.g.: Mike Demuth, NGP; Scott Munro, University of Toronto; Dan Moore, University of British Columbia). Our fifth objective, public education on glaciology, continues in the Canadian Geographic feature Mysteries in the Ice and in the recent appearance of Mike Demuth on the CBC program, Country Canada, January 2003.
Future Meetings and Activities As committee chair, I note progress toward an
effective, collaborative Canadian glacier network, a need identified in the GSC Workshop, Ottawa, January 2000. I have also addressed a need to better relate us to the Cryospheric System (CRYSYS) to monitor global change in Canada, reporting to the annual CRYSYS meeting in Montreal, March 2003, most recently to the world community at the AWS Workshop in Pontresina, an event which we should consider hosting in Canada in the near future.
Other Business The glacier inventory is a continuing matter of
concern, particularly as it relates to water resources in Western Canada; as is continued development of research infrastructure and new personnel, finding additional research positions rather than merely replacing or terminating existing ice science positions. These are key to stronger NGP, CRYSYS and CGU-HS inputs to global change science.

LE BULLETIN DE L’UNION GÉOPHYSIQUE CANADIENNE
President’s Column
In this issue, I would like to present CGU members with a brief report on the recent CGC (Canadian Geoscience Council) meetings in Calgary, which took place on May 29 and 30, 2004, and which I attended in place of CGU President Phil Marsh. These were the CGC Council of Presidents Meeting, the 112th Annual Meeting of the CGC, and the CGC Annual Business Meeting.
The focus of the Council of Presidents Meeting was on geoscience education and outreach in Canada. Various issues were discussed, such as outreach activities currently underway in CGC member organizations, future collaboration, demographic issues in geoscience, and areas of improvement in outreach activities.
Here are some key points summarizing the meetings:
• The meetings were attended by representatives of many of the member organizations of the CGC, i.e., CAG, CGS, GAC, GSC, CIM, MAC, CSPG, CSEG, CGU, PDAC, NRCAN, CANQUA.
• The CGC is aware of the concerns of the CGU (and other organizations) about the current usefulness of the CGC. The CGC is striving to become an umbrella organization which is truly representative of all the geoscience communities in Canada, and genuinely hopes that the CGU and other organizations will be supportive of this.
• The CGC is developing an outreach initiative,
through CGEN (the Canadian Geoscience
Education Network), and encourages each
member organization to work together with the
CGC/CGEN on outreach, perhaps by appointing
an “Outreach and Geoscience Education
Director” on the organization’s executive
committee. Outreach is important to the CGC
because of statistics showing the gradual decline
of geoscience support in Canada. Those
interested should contact Allan Morgan
([email protected]).
Some member
organizations already do a lot of outreach (e.g.,
the MAC, GAC, GSC, CSPG, CSEG, CIM,
PDAC).
• A presentation on the IODP (Integrated Ocean Drilling Program) was given by Kathy Gillis, Canadian IODP Science Director, University of Victoria. IODP is a multi-national program supported mainly by the US, Japan, and ECORD (a consortium of European countries). Canada’s participation is currently as a part of ECORD. If funds cannot be raised in the future, Canada may have to drop out of IODP because of the high cost of membership (about a million dollars per year).

Northern Research Basins
Committee Chair: Dr. Philip Marsh, (Chief Delegate), NWRI, 11 Innovation Blvd. Saskatoon, SK S7N 3H5, [email protected]
8
Deputy-Chief Delegate: Dave Milburn, DIAND, Yellowknife
Past Chief Delegate: Garry Thorne, AECL Research, Pinawa, Manitoba
Mandate and Objectives The role of the NRB working group is to
encourage research and exchange ideas and information on northern research basins, in which snow, ice and frozen ground have a major influence on the hydrological regime. The NRB Working Group normally meets every two years with the meeting consisting of two parts; a symposium at which formal papers are presented; and, a workshop at which special hydrological research topics or issues of international interest are considered and task force reports presented. As part of the International Hydrological Program, the Northern Research Basins Working Group has held regular meetings since 1975 and full membership is currently open to all countries with land territories lying north of the Arctic Circle. In 1998, the Canadian NRB working group became a sub-committee of the Canadian Geophysical Union-Hydrology Section.
As outlined in the NRB Mandate and the Canadian NRB Terms of Reference the Canadian participation in the NRB is limited to 10 delegates appointed by the Canadian Chief Delegate to represent Canadian interest in the hydrology of northern areas. The Canadian Chief Delegate at the 12th and 13th meetings was Garry Thorne. Philip Marsh has since been appointed as the Chief Delegate and David Milburn as the Deputy Chief Delegate for the next 2 meetings (the 14th and 15th NRB Workshops).
Progress on Issues and Objectives The CGU-HS Northern Research Basins
Committee participated in the 14th NRB Symposium and Workshop held in Kangerlussuaq/Sdr. Stromfjord, Greenland from August 25 to 29, 2003. There were 39 attendees, including 10 Canadians, at the 14th meeting, representing seven of the eight member countries which include Canada, Denmark/Greenland, Finland, Iceland, Norway, Russia, Sweden and the USA. The 26 papers in the proceedings, and 33 presented at the meeting, covered a wide range of topics, with the major emphasis on snow, ice and permafrost. Many of the papers also addressed the symposium theme of "The role of high latitudes in global water blance and element budgets”. Reports were received from the an NRB Task Force led by Doug Kane of USA, which is focused on comparison of basin water balance from a range of circumpolar environments. The proceedings of the meeting have been published, and papers have been submitted for consideration for publication in a special issue of the journal, Nordic Hydrology.
Other NRB business and issues:
a) The NRB working group will be constructing and maintaining a Canadian Northern Research Basins website (expected to be www.canadianNRB.com). Work has begun on acquiring background information.
b) Once completed this web page will be linked to the CGU-HS web site, that will provide current Canadian and other information regarding NRB activities.
c) The collection of NRB Proceedings, and special Journal issues, has been updated to include all proceedings. This collection is housed in the library at the National Hydrology Research Centre in Saskatoon.
Future events
Planning has started for the 15th International
Northern Research Basins Working Group Meeting. This
meeting will be held in Sweden, during August 2005.
More
details
are
available
at
http://aqua.tvrl.lth.se/NRB_2005.html. As in past years,
each NRB country is limited to a maximum of 10
delegates. Canadian Delegates will be by invitation of the
Canadian NRB Committee, and approved by the CGU-HS
Executive. Other Canadians may apply to the conference
organizers, and will be accepted depending on space, with
preference provided the official Canadian Delegates.
Glaciers and Environment Committee
Chair: Prof. D. Scott Munro, Department of Geography, University of Toronto at Mississauga, Mississauga, ON, L5L 1C6 CANADA, [email protected]
Vice-Chair: Michael N. Demuth, P. Eng., Geological Survey of Canada;
Advisory Members: Prof. Martin J. Sharp, University of Alberta Dr. Roy M. Koerner, Geological Survey of Canada Jeffrey Schmok, Golder Associates Ltd.
Mandate and Objectives A. Assist the CGU and its executive in promoting
glaciological research that is relevant to hydrological and environmental problems. B. Provide CGU members with information about glaciological research activity, as well as identify opportunities for collaboration among individuals and groups. C. Provide CGU members with information about the scope and extent of glaciological data, and promote efforts to improve accessibility to such data.
9
D. Influence research development by establishing lines of communication with other working groups in snow and ice, such as the Cryospheric System (CRYSYS) to monitor global change in Canada and identify personnel training opportunities.
E. Identify and promote opportunities for educating other members of the scientific community and the general public about glaciers and their role in the environment.
Meetings and Activities a. Michael Demuth and Roy Koerner continue to build
the National Glaciology Program (NGP) in the Geological Survey of Canada (GSC), supported by Natural Resources Canada, Environment Canada and University partners, consolidating research in Arctic and Western Canada. b. A book entitled Peyto Glacier: One Century of Science, M.N. Demuth, D.S. Munro and G.J. Young (eds.), is in the final stages of copy editing. c. Michael Demuth, continues as Canadian Correspondent to the International Glaciological Society, and Canadian National Representative to the International Commission on Snow and Ice. d. Scott Munro has recently completed A revised Canadian perspective: progress in glacier hydrology, a sequel to an earlier review which appeared in Hydrological Processes 14: 1627-1640. e. Scott Munro recently attended the Automatic Weather Station (AWS) Workshop, Pontresina, Switzerland, March 2004, to describe the Western Canada glaciers AWS effort to the international glaciology community and to gain insights on improving the Canadian effort.
Progress on Issues and Objectives The NGP work, in partnership with others, is
central to the first objective of this committee where progress occurs through continued development of the AWS program at the Peyto, the Place and, most recently, the Ram River Glaciers. Toward the second objective, Peyto Glacier: One Century of Science describes the research context for the CGU and others, while A revised Canadian perspective: progress in glacier hydrology reports Canadian research achievements to the world glaciological community. Improvements to the NGP program require new sites in Yukon and British Columbia, and better data management, key points in addressing our third objective. The NGP consolidation effort is essential to our fourth objective: linking research among universities and agencies (e.g.: Mike Demuth, NGP; Scott Munro, University of Toronto; Dan Moore, University of British Columbia). Our fifth objective, public education on glaciology, continues in the Canadian Geographic feature Mysteries in the Ice and in the recent appearance of Mike Demuth on the CBC program, Country Canada, January 2003.
Future Meetings and Activities As committee chair, I note progress toward an
effective, collaborative Canadian glacier network, a need identified in the GSC Workshop, Ottawa, January 2000. I have also addressed a need to better relate us to the Cryospheric System (CRYSYS) to monitor global change in Canada, reporting to the annual CRYSYS meeting in Montreal, March 2003, most recently to the world community at the AWS Workshop in Pontresina, an event which we should consider hosting in Canada in the near future.
Other Business The glacier inventory is a continuing matter of
concern, particularly as it relates to water resources in Western Canada; as is continued development of research infrastructure and new personnel, finding additional research positions rather than merely replacing or terminating existing ice science positions. These are key to stronger NGP, CRYSYS and CGU-HS inputs to global change science.
