Earthwatch Institute is an international environmental charity. It was founded in 1971 as Educational Expeditions International by Bob Citron and Clarence Truesdale. Earthwatch Institute supports Ph.D. researchers internationally and conducts over 100,000 hours of research annually using the citizen science methodology. Earthwatch's mission statement states that the organization "connects people with scientists worldwide to conduct environmental research and empowers them with the knowledge they need to conserve the planet." As such, it is one of the global underwriters of scientific field research in climate change, archaeology, paleontology, marine life, biodiversity, ecosystems and wildlife. For over fifty years, Earthwatch has raised funds to recruit individuals, students, teachers, and corporate fellows to participate in field research to understand nature's response to accelerating global change.2

The story

Earthwatch headquarters are in Boston, Massachusetts. They also have offices in Oxford, England; Melbourne, Australia; Gurgaon, India; and Tokyo, Japan.

Earthwatch was started as Educational Expeditions International in 1971 by Bob Citron, who was a Smithsonian Institution employee, and Clarence Truesdale, the superintendent of Vermont public schools. In 1972, Brian A. Rosborough joined Educational Expeditions International as a volunteer and six months later became president of the newly named Earthwatch. The organization quickly expanded, partnering with scientists around the world to confront threats to wildlife and the environment.

Since 1971, Earthwatch has made notable achievements in environmental research and policymaking. These include

Fielding 1,430 research projects in 131 countries and 46 U.S. states, which have yielded over 2,000 peer-reviewed research publications.

Producing research that has informed approximately 1,200 official environmental policies and wildlife management plans at the local, regional, national, and international levels.

Providing Earthwatch projects over 7 years of support, on average, enabling long-term research goals.

Sending more than 200,000 volunteers into the field to support scientists in the field as research assistants.

Earthwatch Australia is a partner in Bush Blitz, operated by Australian Biological Resources Study with co-funding by Bush Blitz founding partner BHP Billiton.

Products and brands

Earthwatch prioritizes support for research projects that align with the UN Sustainable Development Goals (SDGs).

All projects must contribute to one or more of the following SDGs below and incorporate actions "to combat climate change and its impacts." (SDG 13)

In alignment with UN Sustainable Development Goal 15 (Terrestrial Ecosystems) Earthwatch’s Terrestrial Ecosystems Programs focus on the nexus of habitat preservation and restoration, assessing and mitigating the impacts of a changing climate, and the conservation of biodiversity.

In alignment with UN Sustainable Development Goal 14 (Ocean Ecosystems), Earthwatch’s Ocean Ecosystems Programs focus on conserving biodiversity in marine ecosystems, including open oceans, seas, coral reefs, seagrass beds, kelp forests, and coastal areas, including estuaries, mangrove forests, and saltwater marshes.

In alignment with UN Sustainable Development Goal 11 (Sustainable Cities and Communities), Earthwatch’s Sustainable Cities and Communities Programs focus on research that creates more resilient urban environments.

Earthwatch-supported research has impacted scientific progress and environmental policy in a number of areas. Below are a few relevant examples.

In 2001, Earthwatch volunteer James Murphy unearths a near-complete skeleton of a new genus of dinosaur in the Argentinian Andes, on an excavation led by Dr. Oscar Alcober. The genus, Eodromaeus murphi, is named after Murphy.

Earthwatch-supported research in Belize under Dr. Demian Chapman has led to the listing of five shark species of concern by the Convention on International Trade in Endangered Species (CITES) and the 2020 passage of a comprehensive fisheries bill that protects all rays within 200 nautical miles of its coastline and allows for greater protections of endangered sharks. Chapman’s team also helped cut the total shark catch in Belize from 2018 to 2019 in half by enlisting local shark fishers to tag and release their catches for pay as part of the project.

In 2022, nine years of wildlife monitoring data collected by Earthwatch volunteers in Costa Rica culminated in the designation of Golfo Dulce as an Important Marine Mammals Area, bringing increased protection for whales, dolphins, and other wildlife.

26 years of permafrost data collected by Earthwatch Volunteers research in Canada's Mackenzie Mountains much of it collected by Earthwatch volunteers, has documented an average warming of 0.98 °C—bringing all sites studied dangerously close to thawing. Data from this expedition was cited in Intergovernmental Panel on Climate Change (IPCC) reports in 2019.
