Fifty years of ocean chemistry in one place: GLODAPv3 is here!

Working with marine carbonate-system observations has taught me how much effort lies behind every row of an oceanographic dataset: long hours at sea, careful sampling, laboratory analyses, calibration and quality control. A single bottle of seawater may represent only one place, one depth and one moment, but when many such samples are brought together, they can reveal how the ocean is changing.

Piedmont’s big-two rock quarries: a geology walk

Oakland Geology | 20 July, 2026
This is a walk I led recently, and I like it so much I'm writing it down. As we visit these two major former quarries in the Piedmont bedrock block, we explore some distinctive terrain created during the Pleistocene epoch. We also experience how this beautiful landscape appealed to the people who developed this part of Oakland and Piedmont.

Why the Same Soot Can Warm One City and Cool Another

Every time something burns incompletely --whether in a car engine, a factory furnace, a cooking fire, an agricultural field set alight after harvest, or a vast wildfire sweeping through savanna grasslands-- tiny particles of black carbon are released into the atmosphere. You might know these more simply as soot. These particles are so small that thousands of them laid side by side would barely stretch across the width of a human hair. Yet despite their minuscule size, black carbon (also known as aerosols) are one of the most powerful and perplexing drivers of climate change on the planet.

Exploring salt for hydrogen storage

GEOExPro | 20 July, 2026
Energy stock, a wholly owned subsidiary of the Dutch state-owned company Gasunie, is working on a project called HyStock, which aims to facilitate underground hydrogen storage as a crucial element in the hydrogen econo­my. As part of this project, and prior to any potential cavern development, salt producer Nobian has start­ed to drill three wells...

Burrowing Owls and Eocene Geology, Southwest Montana

Geopostings | 19 July, 2026
The western burrowing owl is North America's only owl that lives underground. They typically use ground squirrel burrows but may also occupy larger burrows made by mammals such as foxes or badgers. I've been fortunate to watch burrowing owls during their recent nesting season in open fields near Three Forks, Montana. Not only are the owls and their owlets fascinating to watch, I'm also interested in their burrows. My interest stems from work that colleagues and I are doing on Eocene fossil burrows (about 39-36 million years in age) located north of Dillon. We are still wrestling with the genesis of the fossil burrows, but it does help to look at a variety of present-day burrows and their associated inhabitants.

TD 2 predicted to strengthen near upper Gulf Coast

Eye On the Storm | 19 July, 2026
A tropical storm watch was issued for the western Florida Panhandle on Sunday, July 19, after large but disorganized circulation over the northeast Gulf of Mexico was designated Tropical Depression 2 by the NOAA/NWS National Hurricane Center on Sunday morning. Although it may struggle to approach hurricane strength, TD 2 could develop a core of [...]

Currently reading Wals (2022): “Transgressive learning, resistance pedagogy and disruptive capacity building as levers for sustainability”

Wals (2022) argues that the classical key competencies for sustainability are not sufficient, that we also need to learn to disrupt, and then learn from the resistance against that. Interesting!! Wals (2022) describes the current systemic dysfunction...
