教师的研究
该系的教员研究地球的远古历史, 气候变化, 海洋系统, 全球周期, 自然灾害. 他们的研究在材料构造方面开辟了新天地, 海洋酸化, 和超级火山, and broadens our understanding of how Earth's oceans and terrestrial ecosystems are being changed by 气候变化 and, in turn, 会影响变化的速度吗.
在课堂教学之外, lab, 还有田野, EOS的教员也经常雇佣学生做实验室助理, 独立研究或荣誉论文的机会.
艾米丽渔夫
和太阳城娱乐以及其他地方的合作伙伴, Peterman uses a variety of methods to explore and quantify solid Earth processes. 她对山带在时间和空间上的演变很感兴趣, and how the strength of the lithosphere evolves during mountain building processes. 要回答这些问题, she explores the deep roots of ancient mountain systems that are exposed at the surface today. 她的研究包括实地研究的结合, 偏光显微镜, 扫描电子显微镜, EBSD, CL, EDS), 地质年代学, 地球化学建模. 例如缅因州的变质作用和变形作用, 原子尺度的地质年代学和地球化学, 以及希腊的超高压地形.

Rachel Beane
Rachel Beane is a geologist who interprets processes that have shaped the earth. 她进行了矿物试验。, volcanic, 以及新西兰的构造研究, Russia, Kazakhstan, Greece, western US, and Maine, 由美国国家科学基金会(NSF)和太阳城娱乐资助. 来解释固体地球的过程, Beane’s lab often uses a combination of methods including field-based research, 光学显微镜, 扫描电子显微镜(EBSD), CL, EDS, and BSE).
Her current projects include interpretation of metamorphism and mineral deformation in Maine and volcanic-plutonic processes in New Zealand. 除了这些矿物和岩石为基础的研究项目, 她还从事与教师发展有关的研究, 科学学习, and diversity, equity, 以及地球科学的包容性实践. This research typically involves literature reviews and statistical analyses. 她欢迎与太阳城娱乐的学生合作.
科林依然
科林依然's research centers on factors that drive primary production in the ocean, a process that forms the base of the marine food web and generates most of the world’s oxygen. 初级生产主要由浮游植物提供燃料, which are critically important microscopic single-celled organisms with rapid growth rates.
Roesler has developed a suite of tools to study phytoplankton on scales relevant to their small size and short life cycles. 用这些传感器系统, 她研究浮游植物在日循环和潮汐循环中的动态, 跨越四季，跨越几十年, observing their responses to environmental changes and recordings changes in the diverse composition of phytoplankton species. 她的工作让她走遍了全球，去过所有主要的海洋.
Because phytoplankton are photosynthetic—acting like a vibrant unseen garden at the surface of the ocean—they absorb some of the excess CO2 humans contribute to the atmosphere. So, 而罗斯勒的研究重点是微小的有机体, her work is helping us better understand global ocean productivity and the ocean's role in balancing the earth’s carbon cycle.
Some of the sensors Roesler uses to do her research are attached to moorings in the Gulf of Maine and in nearby Harpswell Sound. 它们为基于卫星的海洋观测提供了地面真相. 她班上的学生, 还有那些追求独立项目的人, can mine the data of the moorings and/or NASA satellite's long-term data sets to explore a wide range of research questions.

米歇尔·拉维妮
米歇尔·拉维妮's lab researches marine biogeochemistry and paleoceanography across ocean regions and timescales. 与学生和其他合作者, she studies how global 气候变化 has affected the biogeochemical cycling of ocean nutrients and carbon over the past several centuries—and how global warming will impact 海洋酸化 and marine biological response in the future.
Her local projects include evaluating the effects of 海洋酸化 in the Gulf of Maine. The growing concentration of atmospheric CO2 in the seawater is simultaneously lowering the water's pH and increasing the solubility of calcium carbonate minerals. 她与生物学家合作, ecologists, 海洋学家, and geochemists to investigate the natural chemical variability of intertidal ecosystems and the effects on the geochemistry and mineralogy of calcifiers, 比如蛤蜊和龙虾. 这涉及到实地工作, 海岸水质监测, 地球化学分析, 以及生物的培养.
She also uses geochemical “fingerprints” naturally recorded in coral skeletons as proxies for constructing records of past ocean nutrients. Biogeochemical cycles play a key role in connecting interannual to decadal 气候变化, circulation, 生物生产力, 以及大气中的碳吸收. The power of corals to act as continuous recorders of their biogeochemical environment allows her to study remote areas of the ocean where instrumental data have been sparse until recent years, 比如赤道太平洋和深海.
Additionally, LaVigne is interested in science communication and sharing her scientific knowledge with policymakers.
She welcomes collaborations with students who have taken (or are currently enrolled in) 生物地球化学.

Phil Camill
The main driver behind Phil Camill’s research is his quest to understand how changing climate impacts Earth's natural systems, 无论是在现代世界还是在过去的地质时代. 他的研究涵盖了所有的“领域”——生物圈, atmosphere, hydrosphere, cryosphere, 岩石圈-了解景观如何对变暖和, 随着它们的变化, 它们是如何促成或减缓气候变化的. 在过去的三十年里, he has focused on investigating the vast northern ecosystems in boreal and arctic regions, 那里的碳动态和植被模式正在发生巨大变化.
菲尔鼓励对他的工作感兴趣的学生给他发电子邮件, 去他在Roux 128的办公室看看, or, 最有利, 去上他的课, especially 生物地球化学:全球变化的分析.

Jabari Jones
贾巴里·琼斯对河流如何随时间变化很感兴趣, 特别强调人类活动是如何影响河流的. 人类是非常有效的地质代理人，两者都是直接的(e.g.(如筑坝)和间接(如.g.(如气候变化)人类活动改变了河流的形状和功能. In turn, geologic processes like flooding and access to environmental amenities affect human communities, 通常以不平等的方式. 琼斯使用了公开数据的组合, 遥感, 统计分析, and field work to address questions about river change and environmental justice.
琼斯的兴趣不止于河流变化, including community science – where people outside of traditional scientific institutions (government, 大学)有权提出科学问题, diversity, equity, 包括地球科学, 地球科学教育. Jones is new to Bowdoin in Fall 2023 and is looking forward to working collaboratively with students.
