Tessa Michelle Hill is an American marine geochemist and oceanographer. She is a professor at the University of California, Davis, and a resident professor at its Bodega Marine Laboratory. She is a Fellow of the California Academy of Sciences, and in 2016 was named a Leshner Public Engagement Fellow of the American Association for the Advancement of Science. In that year she also received the US Presidential Early Career Award for Scientists and Engineers (PECASE).

Her research and wider public influence focuses on the effects of climate change on the global ocean, including ocean acidification.

Early life and education

Hill was born in Tacoma,Washington, U.S. and raised in the Pacific Northwest, where she attended Stadium High School. She gained a Bachelor in Science degree in Marine Science from Eckerd College.[1] After graduating she studied marine micropaleontology and climate change at UC Santa Barbara. After receiving her Ph.D. in 2004 she was given a University of California President’s Postdoctoral Fellowship at UC Davis for two years, before joining its faculty of the Earth and Planetary Sciences department.[2][3]

Research areas

Hill's research includes methane in the ocean (methane in hydrocarbon seeps, and clathrate dissociation), changing ocean oxygenation and the effects of a warmer more acidic ocean on bivalves, coral, and foraminifera.

Methane in the Ocean

Early in her career, Hill investigated the role of oceanic methane sources in modifying environments at the sea floor and releasing methane to the water column and atmosphere.[4][5] This work utilized modern methane seep environments to investigate the biological and chemical responses to methane. It included reconstructing past intervals of methane and hydrocarbon seepage on the California margin.

Ocean acidification

At Bodega Marine Laboratory (near Bodega Head), Hill and colleagues studied the effect of ocean acidification in the natural laboratory of the California continental margin.[6] Here, upwelling of carbon dioxide-rich water seasonally decreases the pH in local marine environments. One theory about this region is that local fauna would be well adapted to acidic (low pH) water. Hill and colleagues have shown that acidic waters have an adverse impact on growth characteristics of the protozoan zooplankton foraminifera,[7] oysters,[8] and mussels.[9] Oysters and mussels play an important role as foundation species in marine ecosystems, and zooplankton are an important source of food for many organisms. These findings indicate that ocean acidification may have a significant impact on California marine ecosystems.

Hill has been a contributing author to several governmental reports on ocean acidification and climate impacts, including the West Coast Ocean Acidification & Hypoxia Panel,[10][11] Indicators of Climate Change in California,[12] and the Fourth Climate Assessment for California.[13]

Past climate change and the ocean

Hill has utilized past records of climate to understand how temperature, productivity, and oxygen changes in the past have influenced ocean ecosystems. Hill utilizes deep sea corals to reconstruct changes in the ocean through hundreds of years.[14][15] Hill uses microfossils in sediment cores to understand how the ocean has changed over thousands of years, including dramatic temperature and oxygen[16][17] changes associated with the transition from Earth's most recent glaciation to the modern, warmer climate.

Awards and honors

Tessa Hill earned a US National Science Foundation CAREER award in 2013 for [https://www.ucdavis.edu/news/two-win-prestigious-nsf-early-career-awards/ her research] on marine ecosystem shifts due to climate change, and her work to integrate climate science into K-12 education.

In 2014 she was elected Fellow of the California Academy of Sciences.[18] She was named a Leshner Public Engagement Fellow[19] of the American Association for the Advancement of Science in 2016.

Also in 2016, Hill received the US Presidential Early Career Award for Scientists and Engineers (PECASE). The PECASE citation reads:[20]

For her transdisciplinary research that places modern ocean acidification and ocean oxygenation into a long-term Earth-system context, and for training and outreach to K-12 teachers and students that offers them a better understanding of ocean science and climate change through inquiry-based learning.

Public engagement on scientific research

Outreach

In May 2017, Hill was invited to give the Rosenburg Institute Public Forum lecture[21] at San Francisco State University and in May 2018 she gave the Riser Lecture[22] at Northeastern University.

As part of a program supported by the National Science Foundation, Hill leads a program that trains future K-12 teachers in ocean, environmental and climate science. This program has supported curriculum development and research experiences for students in the Math and Science Teaching Program at UC Davis.[23]

Hill serves on the Advisory Council for Cordell Bank National Marine Sanctuary,[24] the Board of Trustees[25] for the California Academy of Sciences and the Board of Trustees[26] for the Society for Science and the Public.

Media

Tessa Hill’s research has been featured in print and radio media on topics concerning climate science, deep sea corals, and ocean acidification. These include a New York Times opinion article,[27] a radio interview on Science Friday,[28] and an interview about the impacts of ocean acidification on shellfish on US National Public Radio (NPR).[29] In addition, she has been profiled in a program featuring climate scientists on NPR.[30]

An interview on corals appeared in Al Jazeera America.[31] Hill published an Op Ed in the Santa Rosa, CA Press Democrat on the role of federal science funding in supporting innovation in the United States.[32] She was profiled as a Scientist-to-Watch in The Scientist magazine,[33] and is a regular contributor of essays and blogs[34][35][36] including for the Union of Concerned Scientists.[37]
