Department of Earth Sciences

Department of Geography and Spatial Sciences

School of Marine Science and Policy

CEOE brings the latest advances in technology to bear on both teaching and conducting ocean, earth, and atmospheric research. We strive to educate well-rounded scientists and policy specialists with the broad vision needed to address today’s global problems.

Concerns such as climate change, globalization and migration, marine pollution, watershed degradation, energy independence and fisheries decline are at the heart of our work at CEOE. Meeting these challenges often demands expertise in several disciplines, and our curriculum and research portfolio reflect this reality.

Our distinguished faculty includes members of the National Academy of Sciences, the American Association for the Advancement of Science, the National Academy of Engineering, the National Association of Geology Teachers, the Archaeological Institute of America, Society of Exploration Geophysicists, a Presidential Faculty Fellow, a Fulbright Scholar, and several University named professors.

Dr. Estella Atekwana
Dean, UD College of Earth, Ocean and Environment



I will be leaving the University of Delaware College of Earth, Ocean and Environment (CEOE) at the end of this month to take a position at the University of California, Davis. It has been both rewarding and gratifying to lead CEOE over the last four years. I have built on the foundation laid by my predecessors and hope that my service has helped to reenergize the college and position it for tremendous future growth. As the Earth continues to warm at an alarming rate, I have high hopes that the foundation established through the launch of the Gerard J. Mangone Climate Change Science and Policy Hub will position CEOE and UD to become a global leader in providing real solutions to the climate crisis and Earth’s other grand challenges.

As I reflect on my time at UD, I am excited about the future of CEOE and am confident that its best days are yet to come. I would like to express my gratitude to President Assanis, Provost Morgan and my fellow deans for this tremendous career growth opportunity. Thank you, too, to my leadership team, faculty, staff, students and the Dean’s Advisory Council for their support in working with me to execute my vision for the college. I hope I have helped make CEOE and UD a better place. I hope to continue to be a resource for the next dean, as well as the students, faculty, and staff that make up this wonderful community.

CEOE Committees & Their Work

In July 2015, the Acting Dean of CEOE formed a college-level Committee on Diversity. The committee was renamed and membership updated in the summer of 2020.

The committee supports the university-wide effort to develop and implement policies that, over long time periods, will enhance the diversity on our campus and ensure we are truly a welcoming, inclusive learning community that reflects our region and country.

Health and Safety Resources

CEOE is committed to collaborating with international partners to advance our joint understanding of the world. CEOE focuses on the following key strategic partnership areas internationally, although individual faculty members have research and relationships in countries around the world.

1. China - CEOE is building on its existing partnership with Xiamen University and expanding to other disciplines beyond marine science and policy.

2. Small Island Developing States (SIDS) - We are fortunate to have ties with many of these countries in the Caribbean, Indian Ocean and the Pacific, and they face unique challenges and opportunities for which CEOE research can be an asset.

3. African Continent - Building on UD's strong faculty leadership and networks in Africa and the immense challenge of environmental and social harm, this continent has a deficit of major partnerships and great potential for high impact research.

The college is examining where and how it can best contribute and lead and where the societal need is greatest. In addressing community needs, the college is fortunate to have valuable in-house capabilities that are already engaged with Delaware’s regional communities and focus on a host of critical issues, including those related to coastal resiliency and waterfront economic sustainability (Delaware Sea Grant), water supply and management (Delaware Geological Survey), and state climatology services (Center for Environmental Monitoring and Analysis).  The three academic units and engagement arms are, therefore, well-positioned to address the increasingly complex societal problems with our legacy of fundamental and applied research and exemplary education, while continuing to explore thematic, interdisciplinary areas that engage students, scientists, stakeholders and decision makers. 

This planning process recognizes that, along with these opportunities, we have a range of in-house challenges that need to be addressed, including priorities for infrastructure upgrades across two campuses in Newark and Lewes with limited investment capital and increasing resources for expanding experiential learning opportunities for students.
