Light Saturated Needle Photosynthesis and Stomatal Conductance

Measurements of instantaneous mid-day light saturated net photosynthesis and stomatal conductance of white spruce needles at sites on the Agashashok, Kugururok, Dietrich and Wind Rivers in the Brooks Range, Alaska. Measurements were made on three or four occasions at each site during the 2013 and 2014 growing seasons. In 2013, measurements were made at the Kugururok, Dietrich and Wind River sites. In 2014, measurements were made at the Agashashok, Dietrich and Wind River sites.
