Last week the international family of Carnegie institutions named nine exceptional individuals as recipients of the Carnegie Medal of Philanthropy, including Kristine McDivitt Tompkins, who co-founded Tompkins Conservation along with her late husband Douglas Tompkins. Carnegie President Matthew Scott wrote about her selection for this honor:
"Kristine McDivitt Tompkins’ philanthropic career dramatically increased in scale with her partnership and marriage to Douglas Tompkins in 1993. Their shared appreciation for nature—its unspoiled beauty and inhabitants—led to the creation of Tompkins Conservation, the umbrella organization covering a range of efforts to preserve, nurture, and restore biodiversity through conservation, restoration, regenerative agriculture, and activism. Although Mr. Tompkins died in 2015, the couple’s shared mission continues to inspire conservation accomplishments of epic proportions. Steadfast in her commitment, Ms. Tompkins, together with her husband, acquired and donated millions of acres of unspoiled new parklands to Chile and Argentina. This achievement rendered the couple the most successful park-oriented conservationists in history. Ms. Tompkins is the former CEO of the outdoor clothing and gear company Patagonia Inc."
Below is a selection of images Scott took at the Tompkins Conservation's Pumalín Park in Patagonia, Chile, showcasing the vast geological and biological diversity of the preserve.

Washington, DC—Rock samples from northeastern Canada retain chemical signals that help explain what Earth’s crust was like more than 4 billion years ago, reveals new work from Carnegie’s Richard Carlson and Jonathan O’Neil of the University of Ottawa. Their work is published by Science.  
There is much about Earth’s ancient crust that scientists don’t understand. This is because most of the planet’s original crust simply isn’t around any longer to be studied directly—it has either sunk back into the planet’s interior due to the action of plate tectonics or been transformed by geological activity at Earth’s surface to make new, younger rocks.
“Finding remnants of this ancient crust has proven difficult, but a new approach offers the ability to detect the presence of truly ancient crust that has been reworked into ‘merely’ really old rocks,” Carlson said.
The approach employed in this study examined variations in the abundance of an isotope of the element neodymium, which is created by the radioactive decay of a different element, samarium.
Isotopes are versions of an element that have the same number of protons, but different numbers of neutrons, causing each isotope to have a different mass.  The isotope of samarium with a mass of 146 is unstable and decays to the isotope of neodymium with a mass of mass 142. (If you’re interested in knowing how, it does this by emitting what’s called an alpha particle—composed of two neutrons and two protons—from its nucleus.)
Samarium-146 is a radioactive isotope that has a half-life of only 103 million years. That may sound like a long time, but in geological terms it is really quite short. While samarium-146 was present when Earth formed, it became extinct very early in Earth’s history. We know of its existence from the study of very ancient rocks, especially meteorites and samples from Mars and the Moon.  
Variations in the relative abundance of neodymium-142 compared to other isotopes of neodymium that didn’t originate from decaying samarium reflect chemical processes that changed the ratio of samarium to neodymium in the rock while samarium-146 was still present—basically before about 4 billion years ago.
 Carlson and O’Neil studied 2.7 billion-year-old granitic rocks that make up a good portion of the eastern shore of Hudson Bay. The abundances of neodymium-142 in these granites indicates that they were derived from the re-melting of much older rocks—rocks that were more than 4.2 billion years old – and that these ancient rocks were compositionally similar to the abundant magnesium-rich rock type known as basalt, which makes up all of the present day oceanic crust as well as large volcanoes such as Hawaii and Iceland.
In more-recent times in Earth’s history, basaltic oceanic crust survives at Earth’s surface for less than 200 million years before it sinks back into Earth’s interior due to the action of plate tectonics. The results presented in this paper, however, suggest that basaltic crust, which may have formed not long after Earth’s formation, survived at Earth’s surface for at least 1.5 billion years before later being re-melted into rocks that form a good portion of the northernmost Superior craton, a geological formation that extends roughly from the Hudson Bay in Quebec to Lake Huron in Ontario.
 “Whether this result implies that plate tectonics was not at work during the earliest part of Earth history can now be investigated using our tool of studying neodymium-142 variation to track the role of truly ancient crust in building up younger, but still old, sections of Earth’s continental crust,” Carlson explained.
 Their findings thus have important implications about the Earth’s earliest crust and the processes that started the formation of Earth’s continental crust.

Carnegie staff scientist Greg Asner has been awarded the 22nd Heinz Award for the Environment,* “ for developing ultra-high-resolution imaging technology that provides unprecedented detail on the biodiversity and health of the world’s forests and coral reefs, and the impact of deforestation, land degradation and climate change.” The annual award comes with a cash award of $250,000.
Asner was hired in 2001 as the Department of Global Ecology’s first staff scientist. Since coming to Carnegie, Asner has pioneered new methods for investigating tropical deforestation, degradation, ecosystem diversity, invasive species, carbon emissions, climate change, and much more using satellite and airborne instrumentation. His innovations measure the chemistry, structure, biomass, and biodiversity of the Earth in unprecedented detail over massive areas not thought possible before. He has developed new technologies for conservation assessments, including tropical forest carbon emissions and stocks, hydrologic function and biodiversity.
Asner leads the CLASLite forest change mapping project, oversees the spectranomics biodiversity project, and pioneered the one-of-a-kind Carnegie Airborne Observatory (CAO) with its laser-guided imaging spectroscopy system. The fixed-wing CAO laboratory reveals the structure and chemistry of the ecosystem below the forest canopy in unprecedented detail.

“Greg’s research has enormous international significance,” commented Carnegie president Matthew Scott. “Andrew Carnegie’s original vision of enabling gifted researchers to follow independent paths to pursue extraordinary discoveries are embodied in Greg’s work. We are extremely proud of his accomplishments and congratulate him on this recognition.”
Asner received his bachelor’s, master’s, and doctorate from the University of Colorado at Boulder in environmental engineering, biogeography, and environmental biology, respectively. In 2007, Popular Science magazine selected him as one of its Brilliant Ten young scientists.

In addition to his work at the interface of ecosystems, land use and climate change, Asner is heavily engaged in teaching others to use his technology for tropical forest management and conservation.   
*The Heinz Awards were created by Teresa Heinz “to honor the memory of her late husband, U.S. Senator John Heinz, the Heinz Awards celebrates his accomplishments and spirit by recognizing the extraordinary achievements of individuals in the areas of greatest importance to him.”
