Meet Henry

Hi, I’m Henry, a climate scientist, educator, and storyteller.

Some of my earliest memories are stitched to water: the scrape of skates on ice, the heavy stillness of a midsummer lake, the gurgling flow of tannin-stained backwoods streams. Growing up in Minnesota, water was everywhere, embodying the seasons, shaping the land, and revealing Earth’s constant change. It was my first teacher too: my introduction to science, and my companion still today. That early connection has carried me from frozen lakes to open oceans, and from quiet paddles to polar expeditions.

Today, I’m a PhD candidate in chemical oceanography at Aarhus University, where I also earned an MSc in Biology. Before that, I studied Environmental Science at St. Olaf College. My research focuses on the polar regions: how oceans absorb carbon, how acidification is evolving, and how melting glaciers reshape coastlines.

Much of my work happens along boundaries: where air, land, and sea meet. In other words, our coastal oceans. These are the places where the pulse of change is most visible, and where we can learn the most about our evolving world. My research isn’t just about collecting water samples; it grows through collaborations with international and local partners, working together to co-create knowledge.

Beyond the field, lab, and desk, I’m passionate about translating science into stories. I look for pathways between data and meaning, between ecosystems and everyday lives. Through writing, teaching, and photography, I aim to make complex ideas feel real, urgent, and human. My hope is to bring polar science to life—not just showing what it is, but what it feels like.
