Life Journey of Scientist Kathy Barbeau
=====================================================================================
In the depths of the ocean, a vital element plays a crucial role in supporting life and regulating the global carbon cycle. That element is iron, and a researcher at the University of California, San Diego (UCSD) is delving deep to unravel its mysteries.
Dr. [Name], who has recently joined Scripps Institution of Oceanography at UCSD, is focusing on natural iron fertilization and how this essential nutrient makes its way into the ocean and interacts with microbes. While geoengineering approaches to iron fertilization have sparked interest as a potential means to draw down atmospheric carbon dioxide concentrations, Dr. [Name]'s work is centred on the natural processes at play.
Dr. [Name]'s research tools are as diverse as the ocean itself. Utilising a variety of instrumentation, they measure trace metal concentrations and the chemical form of trace metals in seawater. Additionally, genomic tools are employed to study how trace elements like iron cycle in seawater.
To gather data on iron concentrations, Dr. [Name] employs specialized sampling gear and works in a clean laboratory with non-metallic materials to ensure the accuracy of their findings.
Dr. [Name] chose Scripps for its reputation as one of the best places in the world for oceanography, as well as the opportunity to collaborate with esteemed faculty and students with a wide range of expertise. Their work is interdisciplinary, bridging the gap between chemistry and biology in studying the iron cycle and its impact on the global carbon cycle.
Their primary objective is to understand the fundamental aspects of the iron cycle, such as what forms of iron are most biologically available and how quickly it is removed from surface waters. This knowledge will provide the basic information necessary to effectively model what's happening with iron in the ocean and how it interacts with the global carbon cycle.
Dr. [Name]'s research is not limited to the ocean's depths. They also aim to understand the climate change impacts on the California Current ecosystem and how it responds to warming events and changes in atmospheric forcing.
While Dr. [Name]'s work is primarily focused on the ocean, it is worth noting that they have a secondary interest in neurodegenerative diseases and the molecular mechanisms underlying Parkinson's disease and related disorders.
As Dr. [Name] delves deeper into the ocean's mysteries, they are shedding light on the complex interplay between iron, microbes, and the global carbon cycle. Their findings will undoubtedly contribute to our understanding of how the ocean responds to climate change and how we might mitigate its impacts.
