Ocean Conditions Indicators Trends

Our stoplight table provides an overview of ocean indicators over time.

The following stoplight table presents a number of climate and atmospheric, local physical, and local biological indicators used to characterize the ocean conditions that may affect the growth and survival of juvenile salmon in the northern California Current. The table compares data across all years sampled, and each indicator is ranked and color-coded based on whether they are “good”, “bad”, or “neutral” for juvenile salmon growth and survival.
