Southern California margin benthic foraminiferal assemblages record recent centennial-scale changes in oxygen minimum zone

July 06, 2020

Microfossil assemblages provide valuable records to investigate variability in continental margin biogeochemical cycles, including dynamics of the oxygen minimum zone (OMZ). Analyses of modern assemblages across environmental gradients are necessary to understand relationships between assemblage characteristics and environmental factors... Read the full publication by Hannah Palmer, Tessa Hill, et al. in Biogeosciences

Exploring the Oceans

Corals are one of the most iconic images of the ocean, offering a spectacular scenery of vibrant, underwater castles for snorkelers and divers. But for marine biogeochemist ​Carina Fish​, these vacation spots aren’t just aesthetically pleasing. Corals are biological time capsules, making them a perfect toolset for Fish to utilize as she uncovers stories about the Earth’s past.

High variability of Blue Carbon storage in seagrass meadows at the estuary scale

April 09, 2020

By Aurora M. Ricart, Ph.D.

Seagrass meadows are considered important natural carbon sinks due to their capacity to store organic carbon (Corg) in sediments. However, the spatial heterogeneity of carbon storage in seagrass sediments needs to be better understood to improve the accuracy of Blue Carbon assessments, particularly when strong gradients are present. We performed an intensive coring study within a sub-tropical estuary to assess the spatial variability in sedimentary Corg associated with seagrasses, and to identify the key factors promoting this variability.

The Seagrass Microbiome Project: Bacteria, the Unseen Heroes?

February 27, 2020

By Jane Park, Undergraduate Intern

 

Though bacteria often get a bad reputation, many organisms depend on them. Humans, for example, have gut bacteria that aid with digestion. Similarly, marine plants, like seagrass, host a collection of microorganisms potentially vital to their health. At UC Davis, researchers have created the Seagrass Microbiome Project to learn about these microbial inhabitants. Through the project, they are looking to see whether certain bacteria are fundamental to the plant’s survival.
