Bryan Mark, together with former BPCRC postdoctoral researcher Alfonso Fernandez, and colleagues from the Moritz Lab and from the University of Maroua, Cameroon, held a workshop in Ngaoundere, as part of the Capacity Building of stakeholders, students and researchers, as part of the MORSL project (Modeling Regime Shifts in the Logone floodplain). This project is funded by the NSF (Dynamics of Coupled Natural and Human Systems (CNH) program) and has the objective to explore the impact of human activities and climate change over the social, ecological, and hydrological systems, in the Northeastern floodplains of the African country.
January – March 2012
On February 15, 2012, the Byrd Polar Research Center presented a series of talks for updating about the ongoing situation of Peruvian Glaciers. The event was catered with Peruvian food and featured Lonnie Thompson, Bryan Mark and Nathan Stansell. The three scientists from the Byrd Polar Research Center described glacier changes they’ve observed in Peru and the implications of changes in the water supply to the people who live downslope.
Glacier environmental change group impacts the world
To capture a picture of how the earth’s climate has changed over time, researchers from Ohio State’s Byrd Polar Research Center travel alpine and polar regions to collect, measure and archive ice cores collected from around the world.
The Big Ten network featured our group to show how Ohio State impacts the world.
Our group, through our colaborator Michel Baraer, has been interviewed during AGU:
“Glaciers in retreat around the world“, The Independent
“Peak water and glacier melt pose thorny problems downstream“, The Daily Climate
“Images Show Big Retreat of Chile Glacier“, Time Science

The purpose of the program is to furnish students a professional learning experience through participation in various projects aimed at the diffusion of geographic knowledge“.
Global Change in Mountains Environments
Location: The Learning Center, Byrd Polar Research Center,
136 Scott Hall
Instructors: Drs. Bryan G. Mark, Geography, and William B.
Lyons, Earth SciencesMountain environments comprise a nexus for interdisciplinary
research because their verticality transects all climatic zones, from
glacierized summits to diverse lowland biomes. As such, they form headwaters of
vital surface water resources, and are hotspots of biodiversity. Furthermore, mountain
environments are most “sensitive” to natural or human-induced
environmental change, a characteristic that calls for the attention of uniquely
trained scientists in identifying linkages between earth systems and social
science.This interdisciplinary graduate student seminar will explore
processes of climate and environmental change in mountainous regions. Our
approach will be grounded in physical biogeochemical processes, but to foster
transdisciplinary literacy we will incorporate both physical and human
perspectives. We will survey current research from different mountain regions,
including Eurasia, Africa, North and South America. Particular attention will
be paid to dynamics of changing environmental conditions over time, and impacts
to physical (e.g. climatic, hydrologic, ecologic) and human (e.g. social,
cultural, economic) systems. Specific content will be directed by students,
whose interests will be developed in individual case studies.
October and November 2011
__Scott Reinemann and Nathan Patrick are lead authors in a new Park Science article that describes our project in Great Basin National Park
and subalpine aquatic ecosystems are highly susceptible to direct and
indirect effects of climate change, making them ideal study sites. We
recovered a sediment core spanning the last 7,000 years from Stella
Lake and a core of the last 100 years from Baker Lake in Great Basin
National Park, Nevada, in 2005 and 2007. We examined the cores for
subfossil chironomid (Insecta: Diptera: Chironomidae; i.e., midge)
remains. The midge communities in the lakes underwent little
compositional change through much of the 20th century; however, after
1980 a rapid lake-specific faunal turnover was observed. Because of
limited dispersal ability and restricted habitats, some lake species
will be extirpated by climate change. Fortunately, lake cores show that
even during the most arid periods the lakes did not completely
desiccate, but continued to support lake biological communities. To
complement the limnological work, an air temperature and humidity
micrologger network was deployed in 2005 and expanded in subsequent
years, now numbering 36 instruments. The sensor network that spans the
full park elevation range (1,639–3,892 m/5,377–13,063 ft) indicates
coherent seasonal and elevational variations, which help to interpret
the paleolimnology data. Climate models indicate increasing temperatures
and uncertain change in precipitation for the Great Basin region.
Although we may not be able to protect all ecosystems faced with climate
change, our collaborative educational research project exemplifies how
the National Park Service is equipped to document and interpret
NASA project in the Bolivian Andes
_ Oliver Wigmore participated in the initial stages of a NASA project in
the Bolivian Andes. The project is investigating high alpine bofedales
(peatbogs). Bofedales are an important habitat for endemic and
endangered species, help to capture, store, regulate and filter water,
provide vital livestock forage, and sequester carbon. The project aims to:Characterize the variability of bofedales throughout the Andes
Provide satellite image analysis of area, distribution and condition
Examine linkages between peatlands and mountain hydrology
Assess the impacts of climate change and glacier recession on bofedalesThis is the first stage of a four year project that will incorporate study sites throughout Bolivia and Peru

_ Photo Name: Lost City, Lonely Dog
In Alex Eddy‘s words: “What is the story of a place? This photo shows two pyramids in Caral, found in the Supe Valley of Peru. Caral is said to be the oldest city in the Americas, serving as the center of the Caral civilization more than four thousand years ago. I was here with a group of scientists, who debated over the unlikely location of this place – seemly too far from the coastal fisheries, too far from other resources farther inland. I wondered about the stories surrounding this place and the people who lived here or just passed by here. I wondered about its dynamic now, and even about the story of this dog, which despite being the same color as the sand, looks so out of place.”
August and September 2011
_ The Imja Lake Expedition
Bryan Mark and Jeff La Freniere participating in the Imja Lake Expedition.
Bryan and Jeff were part of the “2011 Andean-Himalayan Glacial Lake Exchange and Collaboration Expedition”. It was a 18 day field expedition and survey of the potentially dangerous Imja glacial lake in Sagarmatha (Everest) National Park, Khumbu. Strategies for increasing exchange and collaboration opportunities for practitioners from their home mountain ranges—the Andes, Tien Shan, Pamirs, Karakoram, and Hindu Kush-Himalaya—will be developed. Expedition members spent three days camped below the Imja glacial lake to exchange experiences in glacial lake control, mitigation, and management. The expedition had live-blog, Twitter and Facebook during the entire journey. The field expedition (5-23 September 2011) was followed by a four-day workshop “Promoting South-South Knowledge Exchange and Collaboration between Experts and Practitioners from the Hindu Kush-Himalaya, Andes, and Central Asian Mountains for Improved Adaptation and Resilient Livelihoods”, held at the International Centre for Integrated Mountain Development (ICIMOD) (25-28 September 2011).
Karthaus Summer School
Congratulations to Dr. Bryan Mark, who was awarded the Distinguished Undergraduate Research Mentor Award! Dr. Mark won this award for his work with the brilliant young Geographical minds that he has mentored through their research, which is why the award has the above title.
Visit of Dr. Kurt M. Cuffey
Dr. Cuffey is Profesor at the Departments of Geography and Earth and Planetary Sciences, University of California, Berkeley. He visited The Ohio State University for the Edward J. Taaffe Physical Geography Colloquium. He spoke about the major glaciological factors contributing to the rise in global sea level. His topic raises the question of how environmental scientists should respond to requests for quantitative forecasts when quantitative precision is illusory.
