Ship-Based Eddy Covariance Data, 2014 ArcticNet, Northwest Passage and Baffin Bay
During the ArcticNet annual cruises of the research icebreaker CCGS Amundsen, characteristics of the near-surface atmosphere are monitored in conjunction with surface sea water properties to observe the relationship between the surface micro-climate and the air-sea exchange, with particular interest in CO2. Central to this integrated dataset is an eddy covariance system used to monitor fluxes of CO2, H2O, heat and momentum. The system continuously sampled the following variables at a rate of 10 Hz (instrument used to collect each variable is in parentheses, and approximate instrument height above surface is indicated): 3D wind velocity (Gill WindMaster Pro and Campbell Scientific CSAT3 ultra-sonic anemometers) - 15m; sonic air temperature (3D ultra-sonic anemometers) - 15m; CO2 molar concentration (two LI7500A open path gas analyzers) - 15m; H2O molar concentration (two LI7500A open path gas analyzers) - 15m; CO2 mixing ratio (LI7000 closed path system) - 15m; H2O mixing ratio (LI7000 closed path system) - 15m; and 3D ship motion - angular rates and accelerations (MotionPak, Systron Donner) - 13m.
All instruments were mounted on a meteorological tower on the bow of the research icebreaker CCGS Amundsen.
