Title: Carbon cycling in coastal marine sediments: Implications for past, present, and future climates

Abstract: The exchange of carbon dioxide from the atmosphere, into the ocean, and its sequestration in marine sediments is a fundamental control of the global carbon cycle and in turn, Earth’s climate through time. A comprehensive understanding of the processes that control marine sediment biogeochemistry can strengthen our interpretations of past climates, constrain present carbon fluxes, and improve predictions of the planet’s future climate trajectory. However, several critical aspects related to the role of marine sediments in both local and global carbon dynamics remain poorly understood. For example, what are the micro- to macroscale controls of carbon cycling in modern marine sediments? How does the biogeochemical processing of carbon in marine sediments influence our reconstructions of the geologic past? And how will the processing, storage, and fluxes of carbon in marine sediments respond to future climate change and other anthropogenic stressors? In this talk, I will share insights into these questions from different nearshore marine environments and coastal sedimentary systems around the world. Using complimentary field- and laboratory-based experimental approaches and a suite of analytical tools, I will elucidate multiple complexities of carbon cycling in coastal marine sediments and potential implications for past, present, and future climates. Deeply interwoven with this work is building the collaborative and diverse global effort needed to address the climate crisis. I will share insights from my efforts to support, amplify, and center the voices of those most impacted by the current and future consequences of climate change.

Bio: Dr. Alyssa Griffin is a marine geochemist studying carbon cycling in coastal ecosystems and working towards a more just, equitable and inclusive geoscience community. She earned bachelor’s and master’s degrees in Geology from Temple University in her hometown of Philadelphia before working as a Staff Geologist at a leading environmental consulting firm. Her irrefutable passion for scientific research and education led her to pursue a doctoral degree at Scripps Institution of Oceanography where she studied the role of sedimentary carbonate dissolution in shallow coral reefs. She is currently a University of California (UC) Davis Chancellor’s Postdoctoral Fellow and member of the Ocean Climate Lab at UC Davis’ Bodega Marine Laboratory. There, she is researching carbon cycling in temperate seagrasses and other coastal ecosystems. Throughout her career, Dr. Griffin has continually worked to dismantle barriers for future geoscientists and has received multiple honors for these efforts, including the 2018 UC San Diego Inclusive Excellence Award. Dr. Griffin looks forward to continuing to develop geochemical research that centers those most impacted by environmental change and leads to more just, innovative, and inclusive solutions.

Sincerely,
