- Abstract:
- The data collected during fieldwork on the placement will provide additional data for the final chapter(s) of my PhD project on the use of remote sensing for understanding air-sea exchange of carbon dioxide in heterogeneous sea ice environments. The aim of these chapters is to provide an assessment of the effect of heterogeneous air-ice-ocean boundary conditions on air-sea gas exchange, to include work using satellite remote sensing data and in situ data collection in the Antarctic MIZ and Weddell Sea. The work presented in the chapter based on this internship will also be submitted for publishing in an academic journal. During the placement, field work will be undertaken at the eddy covariance tower operating on Qikirtaarjuk Island - a small rock outcrop in Dease Strait located roughly 35 km west of Cambridge Bay, Nunavut, in the Canadian Arctic Archipelago. A detailed description of the site can be found in Butterworth and Else (2018)10. Field experiments at this site will allow concurrent collection of air-ice-sea CO2 gas fluxes using EC equipment, spatial data on ice conditions collected using novel remote sensing techniques and pCO2w measurements from individual melt ponds.The objectives detailed below describe those which will be completed during the 12-week placement: Objective 1: Undertake training in water sample analysis to determine pCO2w and eddy covariance flux processing. Objective 2: Develop knowledge on, and assist with, the set-up of EC equipment and a fixed-point camera system on Qikirtaarjuk Island, Cambridge Bay. Objective 3: Collect a dataset of concurrent EC CO2 fluxes, spatial data on melt onset, melt pond formation and development using drone mounted cameras (visible light, near-infrared and thermal infrared), and pCO2w measurements from individual melt ponds within the flux footprint. The extent and position of the flux footprint will be determined using the Kljun et al. (2015)19 flux footprint prediction model. Objective 4: Collect a dataset of concurrent imagery taken by the fixed-point camera system mounted on the flux tower. Using the drone imagery for validation, processing methodologies and workflows will be determined to extract quantitative data on sea ice and melt ponds from fixed point images with reduced uncertainty, enabling effective long-term monitoring to occur at the site.
