Rapid Warming Events In A Small Coastal Upwelling Embayment, Tatjana E. Ellis
Rapid Warming Events In A Small Coastal Upwelling Embayment, Tatjana E. Ellis
Physics
Temperature variability in the nearshore coastal ocean influences various biological processes and can drive changes in biodiversity and habitat range. Despite recent progress, there are still significant gaps in the understanding of drivers of temperature variability in upwelling bays, particularly at higher frequencies. In this study, we analyzed a decade of nearshore temperature measurements both inside and outside a small coastal embayment located in central California [San Luis Obispo (SLO) bay], as well as temperature data from satellites, to characterize rapid warming events. We found that rapid warming events, defined using rates of temperature change across different thresholds, occurred more …

STAR Program Research Presentations
Zooplankton biomasses in estuaries are often high and represent an important food source for fish, like theendangered Delta Smelt. Human interferences (nitrates from crops, freshwater flow alteration, invasive species introduction…) have altered the structure of the San Francisco Estuary (SFE) ecosystem. We use stable isotope analysis to improve our knowledge of the planktonic food web in the SFE and gain insights into its evolution over the past decades. Every living thing has a specific isotopic signature. For example, in the plankton we study exists Carbon 13 and Carbon 12. Carbon 13 is different only because it has one extra neutron, …
