diatoms
You’re standing in front of a mural inspired by microscopic organisms that help you breathe:
These tiny aquatic lifeforms produce 1 out of every 3 breaths you take.
What are Diatoms?
- Diatoms are microscopic algae (phytoplankton) found in oceans, lakes, and rivers
- They have intricate glass-like shells made of silica
- Each species has a unique geometric design
They are nature’s invisible architects, beautiful and essential to the health of our planet.
why do diatoms matter?
They’re Oxygen Producers
- Produce ~33% of Earth’s oxygen (pie chart with earth)
- Support the entire marine food chain
They’re Story tellers
- Their silica shells sink and preserve a record of Earth over thousands of years
- Scientists use them to understand past climate conditions
They’re an Early Warning System
- Diatom populations are usually stable
- Sudden changes can indicate pollution, warming, or ecosystem stress
- They help us detect problems before they reach the food chain
Diatoms as story tellers:
When diatoms die, their glass shells settle to the bottom of oceans and lakes. They settle layer by layer, year after year.
These layers become a timeline. A memory. A warning.
By studying them, scientists can see when ecosystems were stable and when something changed.
From Microscopic Life to Monumental Art
- Xavier Cortada draws inspiration from diatom forms and patterns
- His murals transform invisible life into public awareness
- Art becomes a bridge between science, community, and action
This mural is part of a larger effort to make the invisible visible.
