Remote sensing

One of the major deliverables of the proposed Chair research program will be a set of analytical tools and algorithms for the remote sensing of key processes in the ice-free surface layer of the Arctic Ocean. These will first be used to analyze the data available over the last decades and detect possible trends, and then to extend observations over the duration of the CERC. The development of these tools will build upon the work of Bélanger et al. (2006, 2007, 2008) in which several new approaches were developed and implemented to monitor the photo-oxidation of CDOM. Several of the remote sensing data used here are free and accessible in near-real time from public web servers.

Current European (MERIS) and US (MODIS) ocean color missions will end in a few years, but the incoming NOAA and ESA-EUMETSAT missions (NPOESS and Sentinel, respectively) guarantee the viability of our observation program. Collaboration with the Marine Core Service of the European Global Monitoring of Environment and Security (GMES) program, MyOcean, will augment our access to remote sensing data. Polar View is another important component of GMES that provides ice data. In addition, jointly with other polar nations (e.g. with Germany at Inuvik, NWT), Canada is investing in a network of ground stations to capture images from the ever-expanding international fleet of satellites. Hence, the proposed remote-sensing program will benefit from increased accessibility to satellite data. Key processes of carbon fluxes that will be derived from the remote sensing of temperature, chlorophyll biomass, CDOM and other variables in the coastal Arctic Ocean are: (1) primary production; (2) the abiotic photo-oxidation of CDOM into CO and CO2; and (3) the bacterial mineralization of DOC.
