Line P

A Long-Term Oceanographic Time Series

Ecosystem Type: Coastal Seas, Open Ocean
Location: Northeastern Subarctic Pacific Ocean, Ocean Station Papa (50°N, 145°W)
Year: 2007 - present

The Line P transect is one of the longest running oceanographic time series in the world, traversing coastal to open ocean water column conditions in the northeastern subarctic Pacific Ocean (NESAP). We participate in Line P cruises to monitor microbial community responses to seasonal dynamics and changing climate patterns. The endurance of this time series is critical to the study of interdecadal processes like ocean acidification, ocean deoxygenation, and Pacific Decadam Oscillation.
