Dataset-specific description

Phytoplankton samples from the PAL-LTER surveys were collected using an 80 µm ring net towed through the upper water column (≤ 50 m depth) for ~ 30 minutes. Phytoplankton were collected during the Oden cruises of 2007/08 and 2010/11 via vertical tows from depths of ~ 20 m with a 30 µm ring net.
