Description

The dataset contains CTD casts taken during two deployments -- KM1016 (August 2010 ) and KM110 (March 2011 ). It includes biogeochemical measurements used to characterize the area around Station ALOHA (22° 45’N, 158° 00’W) An assessment of dinitrogen fixation rates and nifH community structure appears as a separate dataset.
