The Deep Carbon Observatory Diversity Grants program is made possible through support from Alfred P. Sloan Foundation, and is designed to bolster participation of traditionally underrepresented geoscientists in the United States within the Deep Carbon Observatory community. The Deep Carbon Observatory is a global research program to transform our understanding of carbon in Earth. DCO is a community of scientists, from biologists to physicists, geoscientists to chemists, and others whose work crosses these disciplinary lines, forging a new, integrative field of deep carbon science.
