Summary

Today’s book is: At Every Depth: Our Growing Knowledge of the Changing Oceans (Columbia UP, 2024), by Tessa Hill and Eric Simons, which takes readers beneath the waves and along the coasts, to explore how climate change and environmental degradation have spurred the most radical transformations in human history. The world’s oceans are changing at a drastic pace. In response, the people who know the ocean most intimately are taking action for the sake of our shared future. Community scientists track species in California tidepools. Researchers dive into the waters around Sydney to replant kelp forests. Scientists and First Nations communities collaborate to restore clam gardens in the Pacific Northwest. In At Every Depth, the oceanographer Dr. Tessa Hill and the science journalist Eric Simons profile these and other efforts to understand and protect marine environments, taking readers to habitats from shallow tidepools to the deep sea. By sharing the stories of scientists, coastal community members, Indigenous people, shellfish farmers, and fisheries workers, At Every Depth brings together varied viewpoints, showing how scientists’ research and local and Indigenous knowledge can all complement each other to inform a more sustainable future.

Our guest is: Dr. Tessa Hill, who is a professor in the Earth and Planetary Sciences Department at the University of California, Davis. She teaches and researches oceanography and climate change.
