Long Island Sound Shell Day 2023

Let’s shellabrate Long Island Sound Shell Day!
What is Shell Day?
Community science organizations, CT-DEEP, and UConn are collaborating to collect total alkalinity samples around the coast of Long Island Sound during high, mid, and low tides.
Why Alkalinity?
Total alkalinity describes the buffering capacity of seawater. In other words, it’s the capacity of water to resist a change in pH when acidity is added. As CO2 from the atmosphere and from the decay of algal blooms increases in Long Island Sound, total alkalinity guards against pH changes.
Though important to the resilience of Long Island Sound to ocean acidification, total alkalinity is difficult to measure, leading to a scarcity of data. Researchers at UConn and CT-DEEP have established a monthly total alkalinity time series in Long Island Sound, but samples around the Sound are taken at different times. Through a multigroup collaboration, we’re obtaining data across the Sound at the same time, allowing us to understand the spatial differences alone!
