Watch this video to learn what HOT-DOGS is all about.

Station ALOHA is a multidisciplinary hydrostation situated in the North Pacific subtropical gyre.  A host of biological and chemical variables have been measured at this site on a near-monthly basis since October 1988.  Such data sets provide a rare and valuable opportunity to analyze fundamental geophysical dynamics and ecosystem processes.  Fortunately, these data are available for online public access and can be downloaded for students to explore a wide range of research questions.
