Icebreaker Oden
What Are They Doing?
The scientific objectives of the cruise were to collect a range of data in rarely traveled areas of the Antarctic seas and coastline, including the Bellingshausen, Amundsen, and eastern Ross Seas. International science teams worked alongside teachers and other personnel monitoring wildlife, including pinnipeds, cetaceans, seabirds, and penguins; surveying sea ice and meteorological conditions; mapping the chemical, thermal and bathymetric properties of the ocean; and measuring the abundance of plankton and nutrients in the ocean. These studies helped add to our limited knowledge of these remote corners of the Antarctic and allow future researchers to expand their monitoring efforts in these regions.

Location:
SEDNA Ice Camp
What Are They Doing?
Mr. Harris and Dr. Geiger joined an international team of scientists on the SEDNA project, working north of Alaska on the drifting pack ice of the Beaufort Sea. SEDNA was an International Polar Year (IPY) project; the goal of the project was to develop a deeper understanding of how the atmosphere, ocean, and sea ice interact and influence the mass balance of sea ice cover. The results of this study helped researchers better understand the effects of climate change on sea ice cover, leading to better predictions of future changes and assessments of the impacts of these changes on regions and global communities. While in the field, the team took measurements on, above, and under the ice, and compared the ice thickness and distribution with data provided by satellites. Instruments placed on the ice collected and transmitted data via satellite, in order to track the ice conditions even after the science team had left the ice.

Location:
Bering Sea
What Are They Doing?
A diverse research team aboard the U.S. Coast Guard Cutter (USCGS) Healy conducted sampling along a series of transects over the eastern Bering Sea. Research on the ship was multidisciplinary, as part of the Bering Ecosystem Study, with scientists using a variety of techniques to measure the productivity of the Bering Sea ecosystem. Research teams measured the temperature, salinity and nutrient content of the sea water, changes in sea ice cover, and the concentration of nutrients used and released by phytoplankton. They also conducted surveys of zooplankton, fish, seabirds, and marine mammals such as walruses and seals, to assess the health of these populations. These measurements helped give scientists an indication of the status of the Bering Sea ecosystem and any potential changes occurring in the marine environment that might change the continued use of its resources, and the economic, social and cultural sustainability of the people who depend on it.

Location:
Summit, Greenland
What Are They Doing?
This research project on the Greenland ice cap examined the air trapped in firn (old snow that has recrystallized into a more dense substance through the weight of the overlying snowpack) for clues to past climates. The unique characteristics of firn allow the sampling of large quantities of pre-industrial air to explore anthropogenic effects on the atmosphere. While in the field, the team conducted a variety of snow measurements; post-field analysis of the data enabled a better understanding of past climates and the impact of human activity on the Earth's atmosphere.

Location:
Bering Sea
What Are They Doing?
The research team studied the impacts of predators on the main benthic prey species in the Northern Bering Sea. Main predators of benthic organisms include spectacled eiders, groundfish, snow crabs, sea stars, and gastropods. As ice cover declines and groundwater temperatures increase in the Bering Sea, the ranges of mobile benthic predators such as crabs and groundfish may increase and thus affect food availability for other predators such as the spectacled eider. The team used trawls, corers and nets to extract sediment and water samples from the sea floor in order to inventory the benthic population and document any changes occurring within the marine food web.

Location:
Barrow, Alaska
What Are They Doing?
The team investigated the role of carbon in arctic tundra ecosystems. Approximately one quarter of the world's soil organic carbon is stored at high northern latitudes in permafrost and soils. As the arctic environment warms, this carbon may be released to the atmosphere in the form of greenhouse gases such as carbon dioxide (CO2) and methane (CH4). The goal of this project was to understand how changes in a warming and drying arctic environment might affect the balance and stability of the arctic soil carbon. The team measured soil moisture, permafrost depth, carbon dioxide and methane gas in the soil and atmosphere, and surveyed plant composition, function and primary productivity. They also used remote sensing as part of a larger project to investigate patterns of change across the tundra at various scales, from small local changes to landscape level changes. Before Mr. Wilder joined Dr. Obermeier’s team, he had the opportunity to work on an archaeological project outside of...

Location:
Greenland
What Are They Doing?
The expedition members spent five days learning about the research conducted in Greenland, the logistics involved in supporting the research, and had first-hand experience conducting experiments and developing inquiry-based educational activities. The project tied in with the international network Global Learning and Observations to Benefit the Environment (GLOBE), supported by the National Science Foundation, NASA, and GLOBE sponsors around the world. The group arrived in the coastal town of Kangerlussuaq, Greenland on June 18th, where they toured the research infrastructure that supports Danish, U.S., and other international research projects. Tuesday, On June 19th the group flew to Summit Camp at the top of the Greenland Ice Sheet to learn about the research conducted at the Greenland Environmental Observatory at Summit (GEOSummit). Teachers and students participated in data collection for some of the large and ongoing projects, measuring the sun reflectance off the snow and...

Location:
Kuril Islands, Russia
What Are They Doing?
An international team of American, Japanese, and Russian researchers and students examined the 5,000-year history of human-environmental interactions in the Kuril Island chain of Russia. The team combined studies of archaeology, geology, paleoecology, oceanography, and climatology to investigate the records of human settlement and abandonment on the Islands. They also surveyed the geologic evidence of volcanic eruptions, earthquakes, tsunamis, past vegetation and marine conditions, and climatological evidence of past temperature, sea ice, and storminess. The research team traveled by boat to a number of islands to dig archaeological pits, sample soils, and search for buried artifacts and clues to past activity on the islands. The objectives of the project include understanding the environmental conditions of the past and estimating the degree of human vulnerability and resilience to both sudden and gradual environmental changes.

Location:
Kap Hoegh, Greenland
What Are They Doing?
The research team studied little auks (Alle alle), small seabirds also known as dovekies that migrate to the High Arctic to breed in large colonies in Greenland and Spitsbergen. Little auks eat zooplankton, and parents feed their chick almost entirely on copepods (Calanus species). Different zooplankton communities are associated with the different water masses in the Greenland Sea. More importantly, the energy content of individual zooplankton differs among species, with larger species generally providing more energy to predators than smaller ones. Changes in the species composition of zooplankton communities associated with changes in oceanographic conditions in the Greenland Sea therefore directly affects the quality of prey available to Little Auks. The East Greenland population of little auks forages in water that originates from the Arctic and they are able to eat large, energy-rich Calanus hyperboreus and Calanus glacialis, whereas little Auks breeding in areas influenced by...

Location:
Svalbard, Norway
What Are They Doing?
The team traveled to Svalbard, Norway, located in the High Arctic to investigate how high latitude glaciers, melt-water streams, and sedimentation in lakes and fjords respond to climate change. The Svalbard region has been marked by the retreat of glaciers, reductions in sea ice, and measurable warming throughout the Holocene period, and more specifically during the last 90 years. The Svalbard archipelago has preserved geologic records of climate change since the last ice age and into the 20th century, which makes it an ideal location for this study.
