President & CEO
Earthwatch Institute is an international environmental charity[third-party source needed] founded as Educational Expeditions International in 1971 near Boston (USA) by Robert A. Citron and Clarence Truesdale, then superintendent of Vermont public schools. It is one of the largest global underwriters of scientific field research in archaeology, paleontology, marine life, biodiversity, ecosystems and wildlife. For over forty years, Earthwatch has delivered a unique citizen science model to raise funds and recruit individuals, students, teachers and corporate fellows to participate in critical field research to understand nature's response to accelerating global change. Earthwatch's work supports hundreds of Ph.D. researchers across dozens of countries, conducting over 100,000 hours of research annually.
Earthwatch's mission statement is "to engage people worldwide in scientific field research and education to promote the understanding and action necessary for a sustainable environment."
Earthwatch Citizen Science Projects are peer-reviewed, Ph.D led scientific field research which give everyday citizens the opportunity to join research teams around the world to collect field data in the areas such as wildlife conservation, rainforest ecology, marine science and archaeology.
By paying to spend time on a project (ranging from a few days to several weeks), volunteers, corporations and foundations support the critical field research both financially and by providing manpower to collect data. Participants gain first hand experience with science, the scientists and the research area of their projects.
Organization and history
Earthwatch headquarters are in Boston (Massachusetts), as well as offices in Oxford (England), Melbourne (Australia), Tokyo (Japan) and Hong Kong (China).
Earthwatch was founded as Educational Expeditions International in 1971 near Boston (USA) by Robert A. Citron and Clarence Truesdale, then superintendent of Vermont public schools. In 1972, Brian A.Rosborough joined Educational Expeditions International as a volunteer and six months later became full-time president of the newly named Earthwatch.
Since 1971, the worldwide organization has recruited more than 110,000 volunteers who have joined scientists in the field as research assistants, and between them have contributed more than 11 million hours of their time to front-line environmental research all over the world. Earthwatch supports more than 50 vital research expeditions in nearly 40 counties.
Earthwatch volunteers partner with leading scientists in the field to conduct valuable research across four vital areas:
- Climate Change - Climate change poses one of the greatest challenges to the planet. Earthwatch supports research that improves the understanding of how climate change is affecting different environments, and they find ways to help communities reduce their impacts and adapt to changes.
- Archeology & Culture - This research shines a light on the combined genetic, ecological, cultural, and linguistic variation discovered in the native biological and cultural communities. These research programs unearth the past in a way that safeguards the future.
- Wildlife & Ecosystems - Habitats and animals all over the world area threatened. The goal of this research is to create conservation plans and help protect our planet and its inhabitants in today's ever-evolving landscape.
- Ocean Health - This research seeks to protect marine biodiversity with a focus on those parts of the ocean most quickly impacted by society, such as the highly threatened coastal habitats including mangroves and coral reefs.
Current research expeditions being fielded by Earthwatch scientists and volunteers from around the world:
