AB: We will present ultraviolet spectroscopy of polar coronal jets obtained by the Ultraviolet Coronagraph Spectrometer (UVCS/SOHO) during the two SOHO/Hinode observing campaigns (9-21 January and 12-20 March, 2007) for the north and south polar coronal holes. The emphasis is on identifying and tracing polar jets from the solar surface out into the accelerating solar wind and determining their physical properties as a function of height and time. UVCS/SOHO observed ultraviolet counterparts in the extended corona of the hot jets resolved by Hinode/XRT. These polar jets observed by UVCS have different characteristics in the acceleration region of the solar wind than the cooler jets identified at the last solar minimum by LASCO, UVCS, and EIT. Observations such as these are needed to clarify the relationship between the episodic jets, the longer-lived polar plumes, and the fast solar wind. This work is supported by NASA grants NNX06AG95G and NNX07AL72G to the Smithsonian Astrophysical Observatory. SOHO is a project of international cooperation between ESA and NASA.
