Hatfield Marine Science Center

The Newport Line team monitors the pulse of the ocean with year-round, bi-weekly sampling of phyto-, zoo-, ichthyo-plankton, and hydrography in continental shelf and oceanic waters off Newport, Oregon. Originated by the late Bill Peterson, this 25-year time series along the Newport Hydrographic (NH) Line collates key physical, chemical, and biological oceanographic metrics. These data are distilled into a “stoplight” chart of ocean ecosystem indicators used to characterize the habitat and survival of juvenile salmonids.   

The high-frequency NH Line sampling also provides data on critical and emerging issues—like marine heatwaves, ocean acidification, hypoxia, and harmful algal blooms—for fishing communities and federal, state, tribal, and academic organizations.

We work with collaborators from various academic institutions and government agencies to answer ecological questions and address management concerns in the northern California Current Large Marine Ecosystem.
