Particle-associated microbial community dynamics in the Southern Beaufort Sea

Jody Deming, Shelly Carpenter, Eric Collins, Marcela Ewert-Sarmiento, Colleen Kellogg & Min Lin
Our project examines the role that microbes play in attenuating particle flux on Arctic Shelves. We are coupling geochemical and microbiological analyses in a joint effort, with Kirk Cochran's lab at Stony Brook University in New York, to examine particle flux, the diversity and extracellular enzymatic (hydrolytic) activities of microbes associated with particles of different size classes, and corresponding chemical composition and likely source (marine or terrestrial) of the POM. Our specific objectives are threefold:...

Dynamic Inuit social strategies in changing environment: A long term perspective

Max Friesen, Arthur Dyke, Daniel Gendron, James Savelle, Julie Ross, Lauren Norman, Lisa Hodgetts, Peter Dawson & Sarah Finkelstein
For the IPY project Dynamic Inuit Social Strategies in Changing Environments: A Long-Term Perspective, archaeologists and other scientists from across Canada collaborated with Inuit community and heritage organizations to better understand how Inuit culture developed and changed over the past 1,000 years. Six research teams brought together Inuit traditional knowledge, excavation of important archaeological sites, and information about changing Arctic environments. The research took place across the Canadian Arctic, with fieldwork occurring in Nunavut near...

Feeding ecology of the Greenland shark under different ice conditions

Aaron Fisk, Bailey McMeans, Brian Fryer, Carlos Idrobo, Fikret Berkes, Michael Arts, Steven Campana & Susan Dennard
To date, five sampling trips to Cumberland Sound have been completed, three during times of open water (July-August 2007, 2008, 2009) and two during times of ice cover (April 2008, 2009). Preliminary results indicate that the Greenland shark is feeding at a high trophic position and on benthic and pelagic resources, based on chemical tracers. The Greenland shark appears to feed on seal during both open water and ice cover, and does not appear to...

2005-2009 River and Soil Dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) concentrations, Cape Bounty

Melissa Lafreniere
Samples were vacuum filtered using a glass filtration apparatus and precombusted 0.7 um GF/F glass fibre filters. In 2007 and 2008, samples were pressure filtered using a stainless steel apparatus. Filtration apparatus was soaked overnight in 30% hydrogen peroxide or 3% HCl, and triple rinsed with deionised water and sample for each use. Samples were stored cool in the dark (refrigerated) in amber glass EPA vials, and acidified to a pH of 2 upon return...

Lakes and Permafrost in Old Crow Flats

Lance Nagwan, Chris Burn, Blayne Brown, Dougie Charlie, Kibbe Tetlich & Pascale Roy-Leveille
Two sets of thermistor cables will be installed, one at a site in the OCF where drill depth will target 50 m, and the other closer to the community. The site in OCF will be used to obtain the curvature in the ground temperature profile, and establish the apparent response to recent regional increases in air temperature. The sites nearer to Old Crow will be established to 10 m depth, and will be monitored monthly...

The Kwäday Dän Ts'inchi Discovery: Expanding Our Understanding Through Linked Scientific and Community Studies

Sheila Greer, A. P. Mackie, D. Yang, Frances Oles, K. Mackie, Kate Helwig, P. Mudie, Sheila Joe-Quock & Valery Monahan
The Kwäday Dän Ts'inchi Discovery project is one of two confirmed projects within the IPY Activity #435 titled "Recovery Research and Stabilization of Culturally and Scientifically Significant Specimens From Melting Ice and Cryosols." This activity involves science and social science research that has been initiated as a result of the recent melting of glaciers and alpine ice patches. Melting of these scientific "deep freezes" is providing unanticipated data sources that are giving us insight into...

Canadian Coastal Information System (CIS) - CIS Points, Beaufort Sea Coast 1984, 1999 and 2000

Nicole Couture, Paul Fraser & Dustin Whalen
Shore-zone classification data for the Canadian Beaufort Sea coast form part of a GIS database, the Coastal Information System (CIS), developed and maintained by the Geological Survey of Canada (GSC-Atlantic), Natural Resources Canada, at the Bedford Institute of Oceanography in Dartmouth, NS. Coastal attributes in the CIS have been interpreted and mapped from low-level, oblique, aerial photography and video imagery with accompanying audio commentary. The CIS is hierarchical in that coastal forms are classified based...

Plant primary production and goose grazing impact at Fosheim Peninsula, Ellesmere Island

Canadian Wildlife Service Josée Lefebvre & Canadian Wildlife Service Austin Reed
We sample the production of plants (sedges, grasses, forbs and shrubs) and measure the impact of goose grazing in wetlands and mesic habitat since 2007. In both habitat, 6 new exclosures (1 m x 1 m x 50 cm high) made of chicken wire are installed in late June. At the end of the growing season in early August, we sample plant biomass by removing 20 x 20 cm plots in wetland and 20 x...

Vegetation Succession on Drained Lakes in Old Crow Flats, 2007-2009

Lance Nagwan, Trevor Lantz & Erika Tizya
Temperature increases in northern ecosystems are altering the freqeuncy of natural disturbance. Increased disturbance is likely to exert a strong influence on terrestrial vegetation. In the Old Crow Flats in the Northern Yukon, we investigated the effect of catastrophic lake drainage on plant community composition, vegetation structure and microenvironment by contrasting drained lake basins of various ages with several undisturbed terrain types. The vegetation that develops on drained lakes basins is typically dominated by canopy...

Gratton Yves, Marsden Richard, Nudds Shannon, Prieur Louis & Sharatunova Maria
The CTD data was obtained during the 2007-2008 scientific cruise #0802 within the framework of the Circumpolar Flaw Lead Study (CFL). This program included a year round sampling expedition to study the air-sea interactions occurring in the ice-free sections of the southern Beaufort Sea and Amundsen Gulf. The data were collected from March 15 to April 23, 2008, aboard the CCGS Amundsen. There were 132 CTD casts, associated to 10 ice-drift stations, located in the...

N2-fixation data Across the Canadian Arctic

Steven Siciliano, Katherine Stewart & Eric Lamb
Nitrogen inputs via biological N2-fixation are important in arctic environments where N often limits plant productivity. An understanding of the direct and indirect theoretical causal relationships between key intercorrelated variables that drive the process of N2-fixation is essential to understanding N input. An exploratory multi-group Structural Equation Modeling (SEM) approach was used to examine the direct and indirect effects of soil moisture, plant community functional composition, and bryophyte and lichen abundance on rates of nitrogen...

Ecological monitoring of polar bears and seals in Nunavut a step toward the future.

Steven H. Ferguson, Elizabeth Peacock, Andrew Derocher, Mary E. Obbard, Melissa A. McKinney, Nick Lunn, Sebastian Luque, Seth Stapleton, Tara Bortoluzzi & Vicki Sahanatien
We deployed satellite transmitters on live ringed seals captured in Hudson Bay in the summer of 2009. Polar bear transmitters have been deployed in Hudson Bay in 2007, 2008, and 2009. This project will provide management information and advice for the Hudson Bay and Foxe Basin ringed seal stocks by: (1) delineating movements that may bring juveniles and possibly adults into areas hunted by other communities, (2) assessing sex- and age-specific site fidelity of individual...
