Our home base is in the Hawaiʻi Institute of Geophysics at the heart of the UH Mānoa campus. This is where we conduct all of our sample analyses and prepare for field expeditions.
A super-hot argon plasma breaks all chemical bonds in a sample. We use plasma mass spectrometry to measure elements.
Our samples have the lowest levels of Fe, Zn and other metals on earth. We work in a clean room to keep them that way!
Highly-sensitive electrodes allow us to make ultra-trace measurements of seawater micronutrients.
We collect samples from the open ocean, rivers, and everywhere in between.
From the surface it might be hard to tell, but the open ocean is changing. Our measurements help predict how these ecosystems will shift as climate change continues.
The oceans are overturned around Antarctica: Atlantic waters flow into the Pacific, deep waters ascend to the surface. Its effects are felt far and wide, even in the relative warmth of Hawaiʻi.
The ocean is just one part of the great geochemical cycle. By working close to the coast, in rivers, and on land, we can figure out how the ocean gets its elements.
We collaborate with researchers at the Hawaiʻi Institute of Marine Biology (HIMB) to use flow-through mesocosms with seawater from Kāneʻohe Bay. These mesocosms allow us to study how seawater metals impact corals under near-natural conditions.
After the 2022 fire that burned Lahaina in West Maui, we began studying how metal inputs and changing coastal chemistry from the wildfires impacted coral reefs.
