Using energetic ion data obtained by the EPAS experiment on the ICE spacecraft we investigate the three dimensional ion bulk flow in the mass loading region around the comet P/Giacobini-Zinner. We find relatively abrupt changes in flow speed (-100 km s-1) at the boundaries between the pickup and mass loading regions. Flow deflections away from the comet tail of -15¿ are observed at the boundaries with peaks up to -30¿ inside the mass loading region. Ion energies of-300 keV are found inside the mass loading region which suggest the need to consider other ion acceleration mechanisms in addition to solar wind pickup.
