ASP Cambridge Bay Campaign Ice Covered Ecosystem - CAMbridge bay Process Studies (ICE-CAMPS)

Background

Climate change is being felt first and foremost in Arctic regions and is having a dramatic effect on the marine system. Unfortunately, the direction and extent of this change is not well understood due to the lack of baseline studies. New data to help fill knowledge gaps are urgently needed. This is particularly true for the region around Cambridge Bay, Nunavut, where only a few sea ice and oceanographic studies have taken place to date. Building upon the Arctic-ICE program, the process-based and inter-annual aspects of the research planned for ICE-CAMPS are critical for improving our understanding and predicting the impact the rapidly changing ice cover will have on the marine Arctic ecosystem and its associated climate feedbacks.

Project Description

The overarching objective of ICE-CAMPS is to investigate physical and biogeochemical processes operating across the ocean-ice-atmosphere interface during the winter-spring-summer transition to improve our understanding of how our warming climate will affect the ice-covered marine ecosystem of the Canadian Arctic. To meet this objective, we will undertake a set of three themes and subprojects:

Characterization and remote sensing of sea ice melt-dynamics and air-ice-ocean interactions – Sea Ice Geophysics

  • Microwave scattering responses from sea ice pressure ridges (M. Shields, MSc; D.G. Barber, PI, J. Ehn, PI)
  • Physical processes controlling melt evolution (J. Landy, PhD; D.G. Barber, PI, J. Ehn, PI)
  • Air-ice fluxes and the spring/summer evolution of surface heat budget (SEB) (B. Else, PI; T. Papakyriakou ,PI)
  • Polarimetric scatterometer measurements of snow covered first-year sea ice (J. Yackel, PI)
  • Fully-polarimetric C-band remote sensing of thermodynamic changes in snow-covered first-year sea ice (A. Komarov, PhD; N. Firoozy, PhD; D.G. Barber, PI)
  • Retrieval of advanced-melt season parameters over first-year sea ice using satellite remote sensing (R. Scharien, PDF; D.G. Barber, PI)
  • Irradiance in the snowpack and related physical and optical properties of snow on sea ice (G. Picard, PI; F.Dominé, PI)

Environmental factors influencing timing of primary production and its link to sea ice carbon chemistry – Marine Biogeochemistry

  • Underwater eddy covariance measurements of heat, salt, and dissolved oxygen (B. Else, PDF; S. Rysgaard, PI)
  • Assessment of productivity and environmental factors affecting ice algae (K. Campbell, PhD; S. Rysgaard, PI; C.J. Mundy, PI)
  • Temporal trends in relative biomass composition of key ice algae species determined through Fourier Transform Infrared (FTIR) spectroscopy (C.J. Mundy, PI; K. Gough, PI)
  • Phytoplankton dynamics under sea ice in the Canadian Arctic (A. Delaforge, PhD; C.J. Mundy, PI)
  • Mycosporine-like amino acids in Artic sea-ice algal communities (A. Elliot, MSc; C.J. Mundy, PI; F. Wang, PI)
  • Seasonal succession of the microbial community in Arctic sea ice (E. Collins)

Biogeochemical processes controlling atmosphere-sea ice and sea ice-ocean contaminant deposition and ecosystem incorporation – Marine Chemistry

  • Halogen chemistry across the ocean-sea ice-atmosphere interface (W. Xu, MSc; F. Wang, PI)
