Crary Lab

Crary Lab. It is the primary scientific research facility at McMurdo Station, the largest community on the Antarctic continent. Named for geophysicist Albert P. Crary, the laboratory supports a wide spectrum of polar research disciplines under the auspices of the United States Antarctic Program. The facility enables year-round and seasonal studies in fields ranging from glaciology and marine biology to atmospheric sciences and geology.

History and establishment

The laboratory was constructed to centralize and modernize the scientific capabilities at McMurdo Station, which had expanded significantly since the International Geophysical Year. It was dedicated in 1991, honoring Albert P. Crary, a prominent figure in American polar exploration who served as the first person to have set foot on both the North Pole and the South Pole. The establishment of the facility represented a major investment by the National Science Foundation to bolster the infrastructure of the United States Antarctic Program. Its creation consolidated various scattered research efforts, providing state-of-the-art laboratories and workspaces to replace older structures like the original Bio Lab and other temporary facilities.

Scientific research and discoveries

Research conducted within its walls spans the physical, biological, and earth sciences, critical to understanding the Antarctic ecosystem and global processes. Major programs include long-term ecological monitoring of the Ross Sea, ice core analysis for paleoclimatology, and seismic studies of the West Antarctic Rift System. Scientists have made significant contributions to understanding ozone depletion over Antarctica, the behavior of the Ross Ice Shelf, and the unique adaptations of organisms like the Antarctic toothfish. Work here has directly supported large international projects such as ANDRILL, which drilled deep sedimentary cores to reveal the climate history of the Antarctic continent.

Facilities and location

The laboratory is situated on Observation Hill, overlooking Winter Quarters Bay and the McMurdo Sound. Its design incorporates specialized areas including wet labs, dry labs, environmental chambers, microscopy suites, and an aquarium with flowing seawater drawn from the sound. The facility houses analytical equipment such as mass spectrometers, gas chromatographs, and incubators, supporting detailed chemical and biological analysis. It also contains shared spaces like conference rooms, offices, and staging areas for field teams departing to remote sites across the Ross Dependency and the Transantarctic Mountains.

Notable personnel and leadership

The laboratory has been utilized by thousands of researchers from institutions worldwide, including leading universities and federal agencies. Notable scientists who have conducted work here include renowned ecologist Gretchen Hofmann, who studies the impacts of ocean acidification on marine invertebrates, and glaciologist Sridhar Anandakrishnan, known for his investigations of ice stream dynamics. Leadership and technical support are provided by personnel from Leidos, the primary support contractor for the United States Antarctic Program, under the oversight of the National Science Foundation's Office of Polar Programs.

Role in polar science and logistics

As the central hub for science at McMurdo Station, it plays an indispensable role in the logistical chain that supports field campaigns across Antarctica. It provides essential sample processing, data analysis, and communications capabilities before and after deployments to remote field camps. The laboratory's operations are intricately linked with the support services of the United States Antarctic Program, including flights by the New York Air National Guard and cargo handled by the Military Sealift Command. This integration makes it a critical node for international scientific collaboration, hosting researchers from programs like the British Antarctic Survey, Antarctica New Zealand, and the Italian National Antarctic Research Program.
