Research Outcomes



Supported scientists are required to report progress toward research goals and objectives and research outcomes and impacts. 

ANNUAL FIELD REPORTS

PIs submit annual field reports that help us track progress and ensure that the project is aligned with our mission. These reports serve as a valuable resource for Earthwatch participants and support third-party grant opportunities. Here are some examples: 

PEER-REVIEWED PUBLICATIONS

Scientists that we support are expected to produce peer-reviewed publications based on their research findings.  Click here for a bibliography of selected publications from Earthwatch-supported projects.





CONTRIBUTIONS TO SCIENCE

Below is a sample of recent contributions to science made by Earthwatch-supported research:

2016 Dr. Joseph Dudley et al. (The Elephant Factor) expanded on their 1996 and 1998 work that first documented carnivory in the common hippopotamus (Hippopotamus amphibious); their latest data showed that  hippo carnivory causes increased anthrax mortality rates orders of magnitude higher than for other anthrax-susceptible herbivores.

2015 Dr. Lee Dyer et al. (Climate Change and Caterpillars in Costa Rica) found that host diversity affects the proportion of dietary specialists among insect herbivores, and that this shifts globally. The results of this study—which included more than 7,500 species—inform our understanding of how insect herbivores will respond to climate change.

2015 Dr. Charles Higham et al. (Origins of Angkor) re-dated the Angkor sites Ban Chiang, Non Nok Tha, Ban Na Di, and Ban Lum Khoa. Their data showed a new chronology for the Bronze Age, supporting the model that the Bronze Age occurred in the 11th century B.C. These results elucidate the timing of copper base technology in Southeast Asia.

2014 Dr. James Paruk et al. (Loons and the Gulf of Mexico Oil Spill) found that Common Loons (Gavia immer) wintering in the Gulf of Mexico two years after the Deepwater Horizon oil spill showed increasing concentrations and frequency of polycyclic aromatic hydrocarbons. These results demonstrated that the oil spill continues to impact loons wintering in the Gulf of Mexico.

CONTRIBUTIONS TO POLICY

Below is a sample of recent contributions to policy made by scientists supported by Earthwatch funding:

2017 Dr. Cristina Eisenberg et al. (Restoring Fire, Wolves, and Bison to the Canadian Rockies): Native grass data from this project are informing a collaborative IUCN-supported transboundary bison (Bison bison) reintroduction to the northern Rocky Mountains, as well as federal and First Nations fire-management policy to restore bison habitat.

2014 Dr. Demian Chapman et al. (Shark Conservation in Belize) developed a shark fin ID guide that enables customs and immigration officers to enforce the CITES Appendix II listing of scalloped hammerhead (Sphyrna lewini) and great hammerhead (Sphyrna mokarran) sharks.

2014 Dr. Frank Paladino et al. (Costa Rican Sea Turtles): The IUCN used data from this project to support retaining Critically Endangered status of the Eastern Pacific population of leatherback sea turtles (Dermochelys coriacea). The global population listing was downlisted from Critically Endangered to Vulnerable.

2013 Dr. Peter Barham et al. (South African Penguins): This research team made significant contributions to the Biodiversity Management Plan with regard to African penguins (Spheniscus demersus) on Robben Island. This plan was formally accepted into South African law.
