We take a global interdisciplinary approach
INSTAAR's research is truly global in scope, not only spanning latitudes, elevations, and timescales, but crossing multiple science disciplines. This wide range increases our ability to help solve the challenging environmental issues that confront our world.
We work across a number of science disciplines, including in the overlap between them. Small white circles represent individual INSTAAR faculty fellows (as of early 2022). Not shown are our non-traditional fields (for a traditional science institute) such as policy, art, and human dimensions. The INSTAAR members who work in these additional fields help broaden our policy relevance and public engagement.

Research talks
During the Fall and Spring semesters, INSTAAR hosts research talks that are open to the public. They are usually both online and in person. Speakers can be from inside or outside INSTAAR. Occasionally grad students will present research updates and PhD/MS defenses. In the summer, INSTAAR's Mountain Research Station (MRS) hosts in-person seminars open to the public.
Research strengths
INSTAAR has worked at the forefront of these five important research areas for more than half a century.
Cold regions play a crucial role in Earth’s water and energy cycles. And, in the age of global warming, these austere locations are the fastest changing places on earth. INSTAAR has long been a leader in research that seeks to understand rapid change in arctic, antarctic, and alpine climates.
Today, the institute continues this work with an increased focus on interdisciplinary and transdisciplinary research. This includes collaborations between scientists from different fields and collaborations between scientists and indigenous knowledge holders.

Paleoclimate research has never been more important than it is today — it was featured prominently in more than half of the chapters in the latest IPCC report. Without paleoclimate research, we simply wouldn’t know what the Earth’s climate system is capable of.
Formative work on the Quaternary history of Northern Hemisphere cold regions, and on understanding the climatic impacts from the growth and decay of the Laurentide Ice Sheet, helped establish INSTAAR as a world-leading institute. INSTAAR’s paleoclimate research has since expanded to all regions of the globe.

Our institute takes a holistic approach to investigating how landscapes and ecosystems form — from the bedrock to the treetops. INSTAAR leads innovative research efforts into processes that form Earth’s critical zone, and environments as a whole.
Our research has elucidated Earth surface processes all over the planet. In addition, our scientists have created new methods to place landscape processes in geologic time. This includes methods for dating environmental samples and incorporating physical evidence into numerical models.

For more than 30 years, INSTAAR has monitored greenhouse gases and their isotopes. This research provides insight into the sources and sinks of greenhouse gases like carbon dioxide and methane at a global scale.
Measurements are made in the 3 different INSTAAR labs noted below. Collectively, their work provides a vast high-precision, long-term record unlike any other. This data is the basis for dozens of research projects around the world.

INSTAAR scientists drive inquiry into the ecological, biogeochemical, and hydrologic processes that drive changes in high-altitude and polar environments. This research has only become more critical as these environments change in an era of unprecedented human impact.
The (LTER) project based at INSTAAR’s Mountain Research Station (MRS) was one of the founding eight research sites in NSF’s initial LTER network in 1980. 13 years later, The project, located on the coast of East Antarctica, joined the LTER network, with INSTAAR leading stream and ecosystem research efforts.

Delve into the long-term collaborative efforts led by INSTAAR members
INSTAAR's national and international collaborations magnify our efforts and frame our work in a larger context. We lead and manage long-running research programs around the world including two U.S. Long-Term Ecological Research (LTER) programs.

Spanning timescales
INSTAAR researchers work across a broad range of timescales, reconstructing environments of the past, studying present conditions and processes, and improving predictions of our uncertain future.
¶¶ÒõÂÃÐÐÉä half of our faculty fellows study past environments and processes. Most of the focus is on the recent geologic past within the last ~2.6 million years (Quaternary period). Many studies are further focused on the last ice age (~115,000 to ~12,000 years ago) and/or the subsequent warmer and more climatically stable Holocene epoch when humans developed intensive agriculture.
Studies within one timescale often help increase understanding in another timescale. For example, measuring carbon dioxide levels in ice cores improves understanding of past environments which, in turn, feeds into climate models that can make better predictions of future climate change.
Research interests by timeframe
The height of each colored box is weighted by the number of INSTAAR Faculty Fellows researching that discipline/timescale (as of early 2022).
