The SAMOS initiative encourages comparison studies between in-situ platforms. Surface flux reference stations and moored buoy arrays are key components of a sustained ocean observing system. Side-by-side comparisons between SAMOS equipped R/Vs and these moored platforms are necessary to maintain the data quality at these reference sites. In addition, data collected by the SAMOS during the vessel's approach to and departure from moored platforms will be useful to obtain a measure of the spatial variability, even if the vessel's stay at the site is temporally limited.
