Beaufort Sea Coastal Marine ProgramCCGS Nahidik Program

• Background to Northern Energy Development (roots of program)

• Program objectives

• Nahidik overview

• Links to other programs

Northern Energy Development

• Mackenzie Gas Pipeline: Northern Canada’s largest single development

– Environmental Impact Assessment of Pipeline (DFO capacity and research)

– Induced Activities: nearshore and offshore Beaufort Sea

– Complex governance and landclaims

– Challenge for Govt of Canada to prepare

Federal Responsibilities for Northern Energy Development

• INAC• DFO• EC• NRCan• NEB• TC• CEAA• Northern boards

MGP-MCIII (Budget 2005)

MGP-MCII (Budget 2004)

NEDS (Budget 2002)

NEDS – Focus on federal government preparedness for Northern Oil and Gas development, pipeline and exploration

MGP-MCII – Focussed science on research activities entirely in the area of MGP EA regulatory review only

MGP-MCIII – Added science activities associated with induced exploration

Federal Government Strategy

Research Priorities to Meet MGP

1. Gaps analysis workshops– Gartner Lee 2003, YK (Mackenzie

Valley)– Inuvik (Beaufort)

2. Community Consultations– E.g: 6 ISR Communities for Nahidik

3. Co-Management bodies (FJMC) –beluga, seals

4. Regulators needs (DFO-HM, NEB)

5. Industry demands (safety, mitigation)

6. Environmental Impact Assessment gaps.

Northern Energy DevelopmentBeaufort Coastal Marine Program

Program Objectives:

1. To ensure that we better understand the Beaufort Sea ecosystem for decisions related to oil and gas development in the nearshore and offshore.– Parts of ecosystem (biological /

physical / chemical)

– Interactions of ecosystem components with each other and the environment (processes)

– Areas of ecological significance

Shallow Gas Drilling HazardPaktoa Site

Northern Energy DevelopmentBeaufort Coastal Marine Program

Program Objectives:

2. To provide advice on geohazards and allow appropriate mitigation and planning to protect both industry and the environment.

• artificial islands

• ice scour

• shallow gas vents

• sub-surface stability

Northern Energy DevelopmentBeaufort Coastal Marine Program

Program Objectives:

3. Set the stage for enhanced marine research:

1. Canada’s Oceans Act- identify ecological and biologically significant

areas.- identify areas of interest for marine protected areas.

2. Establish long-term monitoring stations for broader Arctic Science under N-CAARE.

3. Links with other vessels in expanded program (national and international).

Northern Energy DevelopmentBeaufort Coastal Marine Program

• Introduction to integrated research program on CCGSNahidik– Marine habitat classification– Fisheries, plankton and

benthic studies– Oceanography – Multibeam work with NRCan– Geohazards (ice scour, gas

vents, artificial islands, etc.)– Bathymetric work with CHS

Physical Oceanography

Bill WilliamsCTD frame

Physical Oceanography• Understand physical and chemical dynamics of the Beaufort Sea

•Mackenzie Plume delineation

• extent, variability

• Help build more robust ecosystem models

CCGS NAHIDIK Fishing Program

A.R. Majewski, J.D. Reist, B.J. Park

Objectives:

Contribute to basic biological/ecological information of offshore fish populations

Information in support of acoustic fish work (Gyselman/Jorgenson)

Information on the use substrate features as habitat 

Provide samples for follow‐on analysis

Methods Overview:Multi‐mesh Gill Nets:60 and 120 m3.75cm (1in.) to 13.75cm (5.5in.)9 locationsSurface and bottom setsTotal depth: 8 – 70m3 – 18 hours

Mid‐water Trawl:3m x 3m gape, 12m length7.5cm (3in.) to 0.6cm (0.25in.)15 locationsSet depth: surface to 50m 30 minutes

Zooplankton and marine larval fish in the Canadian Beaufort Sea Shelf

M. Papst, J. Sareault, S. Wong, Collaborations with the Polish

Academy of Sciences

Objectives•To examine the ecology of the zooplankton and marine larval fish that are using the Beaufort Sea shelf during the ice-free summer months.

•To examine the annual variation of condition and distribution of larval fish such as Arctic cod (Boreogadus saida).

•To determine if different species of larval marine fish can be used as ecosystem indicators.

•To identify areas of high ecological importance to larval marine fish.

Benthic community research from the Nahidik cruises

Purpose of studies

• Taxonomy of Beaufort Sea benthos poorly understood

• Benthic Invertebrates important ecosystem component– Food for fish, and marine mammals– Indicator of healthy ecosystem

• Useful for monitoring programs• Useful in habitat assessments (special features)

Long-term ResearchNorthern Oil and Gas MC IV,V?

• Long-term research and monitoring to test EIS predictions, effectiveness of mitigation, respond to accidents, and future geographic expansion of MGP development

– Post construction impacts – Cumulative Impacts– Broader off-shore development –

Beaufort, but also High Arctic– Expansion of pipeline infrastructure

along corridor (new areas)– Respond to un-anticipated events

and new community concerns
