FEATURED TOPIC

What is Ocean Acidification?

Absorption of carbon dioxide by the ocean is altering ocean chemistry. Carbon dioxide is an acid gas-- when it dissolves in water it forms carbonic acid, which effectively makes the water more acidic. Although ocean water is naturally basic (pH > 7) the process of absorbing carbon dioxide decreases the pH, which means it is becoming more acidic.

NUTRIENT BIOEXTRACTION

PSI examines nutrient bioextraction in Budd Inlet

Reducing nutrient sources has become a top priority for many jurisdictions. By decreasing nutrient loading, widespread problems with thick algae blooms and oxygen depletion can be prevented. Source control is a critical step-- but can nutrients be removed once they enter the marine environment? This project explores that question!
