Project Description
The Wake Island Passage Flux Experiment (WIFE) was carried out from 2003 to 2005 to clarify and accurately quantify the temporal means and variations of heat content and volume transport of abyssal water in the North Pacific. WIFE consisted of repeated shipboard hydrographic surveys and mooring array observations along a line across a deep passage just south of Wake Island Passage (Uchida et al. 2007b). This study was designed to obtain time series measurements of heat content by using moored conductivity– temperature–depth (CTD) recorders and of volume transport by geostrophic calculations based on density measurements from the moored CTDs referenced to velocity measurements by moored current meters also deployed during the WIFE. Since changes in temperature and salinity of the abyssal water are small, moored CTD data must be accurately calibrated to shipboard CTD data.
