Research on climate change over the Pacific Ocean Side of Antarctica Jang Bogo Research Station is expected to provide an ideal platform for the research on climate change over the Pacific Ocean side of Antarcica. The winter-over research program will contribute a great deal to understanding the rapid climate change in the region; for instance, a precise year-round measurement of green house gases will be an asset to the science community of the region.

Participate in the global atmosphere watch (GAW)

A climate observatory, which Korea is planning to establish to participate in the global atmosphere watch (GAW) program in Terra Nova Bay, will provide a useful, long-term database regarding the atmispheric composition. The nearest regional GAW station is located at McMurdo, 300km away from Terra Nova Bay. The climate-monitoring program in Terra Nova Bay, the new Korean project, will also provide valuable data about climate change on the Pacific side of Antarctica.

Reconstruction of paleo-climate and enviroment

from glaciers

Glaciers, often called frozen time capsules, contain valuable record of changes in atmospheric environment over time. Polar ice sheet is of special interrest, because air bubbles trapped in ice allow us to uniquely document levels of greenhouse gases such as CO2 and CH4 in responese to climate change. Reconstruction of changes in past atmospheric composition from Northern Victoria Land's ice core may be over the time scale of hundreds of thousand of years.

from sediments

To decipher natural environmental changes in the future we should understand the dynamic interactions among the atmosphere, ocean, cryoshere and lithosphere. Reconstructing past climatic changes help us to understand how the climate system works and interacts with other system. Marine sediments under Ross Ice shelf and in Terra Nava Bay record past changes in natural environmental changes. Korean scientists plan to reconstruct the environmental record of the Quaternary period of Ross Sea area.

Antarctic neotectonics

Antarcitic neotectonics including volcanism is an important subject to understand the geological processes as well as the development of continental glaciations. Mt. Melbourne in Terra Nova Bay is one of a few exposed active volcanoes in Antarcica. The location of Mt. Melbourne and its volcanic activities are associated with Ross Sea rifiting and uplift of the Transantarctic Mountains rift shoulder. Because the specific seismicity and physical structures in this area have not been fully studied yet, Korea is proposing to install multifold stations including seismic, infrasound, camera, and GPS system at Mt. Melbourne to observe microseismic activities caused by its volcanic activities.

Upper atomospheric observation

Terra Nova Bay is located at geomagnetic latitude of 77˚S, which will afford a good view of the site to check out upper atmospheric phenomena including Aurora. Although the upper atmosphere is currently well ovserved via such tools as ionosonde, MF radar and GPS scintillation receiver, its system is too complicated t fully analyse only with a limited number of measurements. In fact, the system consists of ionosphere, thermosphere and mesosphere, which interact with both the magnetosphere and the lower atmosphere. To understand the system comprehensively and extensively, therefore, a set of simultaneous and multidimensional observations must be surely made. So far, there has been no observation for the thermospheric winds and ionospheric drift velocity, which are crucially important for the study of the coupling getween the ionosphere and thermosphere. Korea will install Fabry Perot Interferometer for the thermospheric winds and Digisonde for the ionospheric drift velocity at the new station. In addition to the regular operations for long-term observations, it may also be needed to work with other stations to coordinate observations, different or similar, on specific events such as magnetic storms.

Long-term oceanographic monitoring

The Ross Sea contonental shelf represents a unique habitat : for example, the food web, in this region, is substantially different from other areas of the Southern Ocean because of the extreme seasonality, numerous polynyas and extenxive ice shelf. This ecosystem is also subject to physical changes occuring in the area. the Ross Sea, along with the Weddell Sea, is one of the places of extensive bottom water formation in the Antarctic. The Ross Sea is experiencing rapid fresheming that may result in change in the rate of bottom water formation and in turn global climate change. While there has been a 10% increase in Antarctic sea ice extent in the Ross Sea region, regional sea ice has decreased in the west of the Antarctic Peninsula and this should have far-reaching consequences. Therefore it is of great importance to identify major oceanographic and atmospheric parameters that are responsible for the freshening and to monitor the variability in the rate of bottom water formation. The observation of sea ice extent and physical processes are also important topics that need to be timely addressed together. Korean scientists plan to establish long-term oceanographic data series that will assist us in detecting the trend with comparison to other regions and predicting the future changes.

Long-term ecosystem monitoring

Long-term monitoring research around Antarctic research station offers valuable data to understanding hole Antarctic ecosystem under the climate changes. The year-round monitoring of ecosystem based on Jang Bogo Reaserch Station will contribute to better understanding ecosystem dynamics in Terra Nova Bay.

Antarctic meteorites (KOREAMET)

Meteorite is a natural object originating in outer space that survives an impact with the Earth's Surface. Antarctica is an ideal place to recover meteorites which lie on the surface of the ice. A Korean expedition was launched in 2006 dedicated to the search for Antarctic meteorites and collected meteorites around Thiel Mountains. Korean meteorite research team(KOREAMET) will collaborate with Italian team and expand area for exploring to Northern Victoria Land.
