Brief description

The datasets measure the Euphotic Depth (Zeu) of Australian oceans. They are derived products from MODIS (aqua) images using NASA's SeaDAS image processing software. The extent of the datasets covers the entire Australian EEZ and surrounding waters (including the southern ocean). The spatial resolution of the datasets is 0.01 dd. The datasets contain 36 monthly Zeu layers between 2009 and 2011. The unit of the datasets is metre.
