Maddie is a Program Manager for TOF’s Programs and Consulting Team with a current focus on deep seabed mining, underwater cultural heritage (UCH), and climate geoengineering. She is passionate about increasing access to science and policy, allowing her to combine her background in physical sciences, interest in digital communications, and research focus on environmental policy in her work at TOF.
Maddie has a Master’s in International Environmental Policy with a specific focus on Ocean and Coastal Resource Management from the Middlebury Institute of International Studies in Monterey. She specialized in international and US marine policy legislation and completed research projects on equity within the law of the sea (UNCLOS), the viability of a deep seabed mining moratorium in the US, and the impacts of sea level rise on politically unique coastal communities.
During her time at the Middlebury Institute, Maddie received a Fellowship with the Center for the Blue Economy and worked with Plastic Tides to support their plastic-free advocacy, and TOF on deep seabed mining.
She became a Mentor with Plastic Tides’ Global Youth Mentor Program, supporting three high school students as they developed community based projects to combat the plastic pollution crisis.
She loves making handicraft projects for family and friends, seeing live music, and nerding out about pop culture. She also holds a BS in Chemistry from Georgetown University.

The Ocean Foundation was thrilled to participate in the 2024 United Nations Ocean Decade conference in Barcelona, Spain. The conference brought together scientists, policymakers, youth, Indigenous people, and local communities …
Is it loud enough yet? Protests, Indigenous Voices, and the Business Case for DSM at the March 2024 ISA Meetings
The Ocean Foundation’s Deep Seabed Mining (DSM) team is happy to have participated again in meetings of the International Seabed Authority (ISA) in Kingston, Jamaica. Negotiations continue, and despite ongoing cooperation, the regulations are still far from being completed, with divergent views on fundamental concepts blocking consensus on key issues.
No-Mining November: The Ocean Foundation’s ISA Council Check-In
The International Seabed Authority’s third set of meetings held in Kingston, Jamaica wrapped up last week with little fanfare and fewer decisions. The Ocean Foundation participated in the meetings for the third time this year, continuing to speak with delegates on our key goals.
Don’t Shade the Ocean
We need sound legal tools to address side effects from climate geoengineering projects that could endanger the marine environment. These unwanted impacts include the ability of the seas to produce food and oxygen and absorb carbon dioxide and excess heat.
Our Mission to Defend The Deep
The Ocean Foundation was on the ground of the 28th meeting of the International Seabed Authority in July 2023 for all three weeks to raise our topline messages on finance and liability, underwater cultural heritage, transparency, and stakeholder engagement.
The 8th Wonder of the World: Mining’s Threat to our Underwater Cultural Heritage
With 80% of the seabed unmapped, Deep Seabed Mining poses a wide array of threats to Underwater Cultural Heritage in the ocean.
Climate Geoengineering and Our Ocean: Considering Ethics, Equity, and Justice
The technical and ethical uncertainties around climate geoengineering are numerous in both carbon dioxide removal and solar radiation modification
Planetary Sunscreen: Solar Radiation Modification
Solar Radiation Modification (SRM) is a form of climate geoengineering that aims to increase the amount of sunlight reflected back into space – to reverse the warming of the planet.
Trapped in the Big Blue: Ocean Carbon Dioxide Removal
Carbon dioxide removal (CDR) is a form of climate geoengineering that seeks to remove carbon dioxide from the atmosphere.
Endless Unknowns: Climate Geoengineering
The planet is getting closer to exceeding the global climate target. Because of this, there has been an increased focus on climate geoengineering.
