We are saddened to share the news that John A. Wott, retired professor emeritus, Urban Horticulture at the University of Washington and former Washington Park Arboretum director, passed away on August 28, 2021, at the age of 82.

Volcanic eruptions may have spurred first ‘whiffs’ of oxygen in Earth’s atmosphere

A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere. This would change existing stories of Earth’s early atmosphere, which assumed that most changes in the early atmosphere were controlled by geologic or chemical processes. Though focused on Earth’s early history, the research also has implications for extraterrestrial life and even climate change.

Kelp farming and the potential for new maritime markets in Puget Sound

You have likely heard of shellfish and finfish farming, but a new type of cultivation is emerging in our region: seaweed farming.

Official recognition of Southern Ocean brings Earth’s total to five

Growing up, most of us learned there were four oceans making up 71% of earth’s surface: The Arctic, Indian, Pacific and Atlantic. Now, there are five. The Southern Ocean is the most recent addition, officially recognized by National Geographic in June of 2021 on World Ocean Day. While the other four oceans are defined by continental boundaries, the Southern Ocean is different: it is the only ocean connecting the other oceans through a current that circles the entire globe.
