Deep Sea Ecology

The deep-sea is the Earth’s last great wilderness, and yet we see signs of human impacts on every ROV and Submersible dive, even at the very bottom of the Marianas Trench. My work focuses broadly on how human activities shape and reshape the deep ocean. My current research portfolio includes understanding the environmental impacts of deep-sea mining, assessing the accumulation of microplastics at hydrothermal vents and methane seeps, and exploring the interconnectivity of life on the deep seafloor.

Conservation Technology

The ocean is the common heritage of humankind, but access to the tools needed to study, understand, and protect the ocean are not accessible to the vast majority of ocean stakeholders. My work developing low-cost open-source oceanographic instruments builds capacity and reduces barriers to knowledge production, so that those disproportionately affected by our changing oceans can access the tools necessary to quantify those changes.

Ocean Education and High Seas Policy

From bespoke apps to model sea level rise to month-long intensive programs on underwater robotics, I create programs to engage, educate, and inspire.

I also work to transform ocean literacy into policy action. This includes overseeing a trade journal covering the deep-sea mining industry, consulting with companies, governments, and NGOs on frameworks for high seas policy, and supporting community-led campaigns for ocean protection.

Outreach and Science Communication

Southern Fried Science: For over 15 years, I have served as the editor-in-chief of Southern Fried Science, which, at it’s peak, was the most widely read marine science and conservation blog in the English language. It covers a broad variety of topics ranging from shark ecology to technology tutorials to life as a scientist.

The Deep-sea Mining Observer: Conceived of as a trade journal to cover the nascent deep-sea mining industry and to galvanize global attention on this emerging issue, the Deep-sea Mining Observer ran for six years, publishing a monthly newsletter featuring articles about environmental issues, technology, policy developments, and other pressing issues facing the industry.

St. Michaels Floodwatch: To help the residents of St. Michaels better visualize and understand how sea level rise will effect the town in the coming decades, I created an interactive visualization of the nuisance flooding projections used by the St. Michaels Climate Change/Sea level Rise Commission.

Science Fiction

As a lover of all thing science fiction and fantasy, I self-published two science fiction novels set in an imagined post-climate catastrophe future, one novella envisioning what it would be like to sail on the methane seas of Titan in the far future, as well as a few short stories. It continues to be a source of pride that my sole Nature “paper” is a short story about zombies.

A lifelong student of the craft, I work with local cull wood to create custom, craftsman-inspired furniture built to last. Over on Southern Fried Science, I occasionally address topics where woodworking overlaps with conservation or life as a scientist.
