Acidification impedes shell development of plankton off the U.S. West Coast
Results from a 2016 research cruise show ocean acidification has interfered with shell development of zooplankton that are a critical part of the marine food web.

The 2014‐16 Pacific Warm Anomaly‐El Niño sequence significantly changed ocean conditions in the California Current System (CCS), but impacts of these anomalies on nutrients, chlorophyll‐a, and pH, and comparisons to past El Niño events, have not been well described. We examined nine years (2010‐2018) of data from two ocean moorings that provide hourly measurements at fixed locations in the southern CCS, allowing us to determine both sub‐seasonal and multi‐year ecosystem changes.
