AB: Plasma measurements in the Earth's magnetotail have revealed occasional existence of multiple plasma components. It is uncertain whether the bulk plasma moments computed can truly represent the transport properties in such occasions. In this work, we examine the influence on the transport of plasma, magnetic field, and energy by the presence of multiple plasma components in Geotail plasma measurements. We use the automatic detection technique newly developed by Ueno et al. [2001] to examine three-dimensional plasma measurements in the Earth's magnetotail. Two events are examined in detail, one occurring in a magnetic reconnection interval during the substorm expansion phase while the other occurring at plasma sheet thickening during the substorm recovery phase. Similarities and differences in transport characteristics deduced from the bulk plasma moment procedure and that from the multi-component procedure are presented, including implications of these results.
