2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
Sea ice concentration (SIC) calculated from the AMSR-E by using NASA Team2 (NT2) algorithm has proven to be very accurate over sea ice in Antarctic Ocean. When glacial ice such as icebergs and ice shelves are dominant in an AMSR-E footprint, the accuracy of NT2 algorithm is not well maintained. We extracted the concentrations of sea ice and glacial ice ...

On the 4thAugust 2010, Very Low Frequency (VLF) chorus was observed on Marion Island (L = 2.6). This is a very unusual occurrence as chorus is thought to be generated outside the plasmapause, which would only extend to such low L during periods of severe geomagnetic activity. A similar event was observed at Palmer Station, Antarctica (L = 2.44) during ...
Sea ice concentration (SIC) calculated from the AMSR-E by using NASA Team2 (NT2) algorithm has proven to be very accurate over sea ice in Antarctic Ocean. When glacial ice such as icebergs and ice shelves are dominant in an AMSR-E footprint, the accuracy of NT2 algorithm is not well maintained. We extracted the concentrations of sea ice and glacial ice from two ENVISAT ASAR images of southern Antarctica, and compared them with NT2 SIC. The result showed that the NT2 algorithm underestimates the concentration of glacial ice. We also found that glacial ice occupies a unique region in the PR (polarization ratio), GR (spectral gradient ratio), PRR (rotated PR), and ΔGR domain different from other types of ice such as ice type A, B, and C, and open water. This implies that glacial ice concentration can be added as a new category of ice to the NT2 algorithm.
The sea ice in polar region has been shrunk and thinned considerably with the rampant global temperature during the last few decades. It has already shown dramatic effects on regional water balance, ocean circulation and global climate. Nowadays, an extensive investigation and understanding of the environmental change in polar region becomes a crucial task. However, difficulties resulting from transportation, extreme weather, and seasonal cycle, as well as the lack of satellite coverage make the polar research extremely challenging. Successful launch of FORMOSAT-2 satellite by National Space Organization, Taiwan (NSPO) in 2006 is supposed to resolve the limitation of polar observation by providing daily high resolution images (8 m MS and 2 m Panchromatic) near two poles. This paper presents preliminary findings from time-series FORMOSAT-2 images over the Arctic sea and Amundsen- Scott South Pole Station. Results indicate that wind erosion and ocean circulation shear force may take part in shaping the Arctic ice. In addition, the wind field over the Antarctic may be estimated.
The goals of this study are to observe the development of multifreqency microwave emissivity (e) of new and young sea ice grown under dynamic conditions, and to investigate the effects of ice growth and structural changes on its microwave signature. In particular, the authors are interested in three ice types, whose signatures are particularly difficult to investigate under normal field conditions. Unconsolidated frazil ice and pancake ice, which occur when ice forms in a wave field under stormy conditions, are found in abundance in the marginal ice zones of the Arctic and Antarctic sea ice packs. They make up a significant portion of the area covered by the new and young ice. Because new and young ice types are weaker than the surrounding thick ice and fracture first under conditions of high ice stress, a large percentage of the ridged ice consists of thin saline ice. As the ridges evolve, brine drains out of the elevated parts causing substantial changes in the permittivity distribution which can affect their microwave emissivities. Previous studies have shown that the microwave signatures of these ice types appear to be distinct in several respects, but the data from these experiments are sparse and the uncertainties are still relatively large. The differences between the microwave signatures of these ice types and those of first-year (FY) ice types grown under relatively calm conditions are important for interpreting satellite derived ice concentrations and ice type distributions. This paper presents the results of the author's latest studies of the microwave emissivities of these ice types.
On the 4thAugust 2010, Very Low Frequency (VLF) chorus was observed on Marion Island (L = 2.6). This is a very unusual occurrence as chorus is thought to be generated outside the plasmapause, which would only extend to such low L during periods of severe geomagnetic activity. A similar event was observed at Palmer Station, Antarctica (L = 2.44) during the Halloween storms of 2003. The 2003 event had a minimum Dst of around -350nT, while the 2010 event occurred after a significantly smaller storm (Dst ~ -70nT). A further difference is that the 2003 event occurred during solar maximum, while the 2010 event occurred during a period where the Sun had been unusually inactive. The spatial extent of the 2010 event is discussed, and data from a broadband VLF ground receiver is presented. Empirical plasmapause location models reveal that Marion Island was just within the plasmasphere at the time of the event. Preliminary analysis of low resolution VLF data from another high latitude station shows that a similar emission was observed at that site, but at a slightly later universal time, which indicates that the generation region was moving. This movement is likely linked to the eastward drift of electrons, and also possibly to the plasmapause relaxing to its quiet time position.
The Southern Ocean (SO) is an important contributor in determining how the Earth's climate is changing. The SO plays a major role in global ocean circulation, a system of surface and deep currents, linking all oceans and one of the fundamental determinants of the Earth's climate. Despite the recent increase in our understanding of the SO system, there is still uncertainty in the fluxes and transport of fresh and salt water within this region. Additionally, waters at mid-depth in the SO have increased in temperature at a faster rate than the average rate for the entire global ocean. In this study we used Sea surface salinity (SSS) derived from the NASA's Aquarius/SAC-D salinity mission to estimate surface salt fluxes. Depth-integrated salt and volume transports will be estimated using Simple Ocean Data Assimilation (SODA) reanalysis. The upper 2000m of the Southern Ocean has noted the most intensified change in temperature and salinity. Additional analysis with SODA reanalysis showed the changing transports at each of the basin's boundaries, increasing meridional magnitude and decreasing in zonal. Transports are important as the relationship to movement of salt, heat, gases, etc., and can be used to suggest the intensification of the water cycle.
Global totals of ice area and volume for mountain glaciers are small compared to the Antarctic and Greenland ice sheets, however, their present contribution to sea level rise (SLR) is on par with the ice sheets. Alaska Glaciers provide the largest contribution of all mountain glaciers to SLR. We discuss the use of spaceborne remote sensing techniques to study Alaska glacier contributions to sea level and suspected changes in ice velocity. Direct calculation of ice volume changes and rates of change on Kenai Peninsula glaciers are based on differences in USGS and SRTM DEMs and airborne Lidar profiles. A preliminary study of ice velocities on the Seward Glacier using L-band InSAR from PALSAR is presented.
In recent years there is growing interest, on the part of the remote sensing community, in using the Antarctic area for calibrating and validating data of the low-frequency satellite-borne microwave radiometers. In particular, the East Antarctic Plateau appears to be suited for this purpose. The reason of this interest lies in the size, structure, spatial homogeneity and thermal stability of this area. This is particularly interesting for low-frequency microwave radiometers since, due to the low extinction of dry snow, the upper ice sheet layer is almost transparent and the brightness temperature variability is therefore extremely small. In preparation for the November 2009 launch of the ESA's SMOS satellite, an experiment called DOMEX, which included radiometric L-band measurements was started in the Austral summer 2009. Data acquired in the campaign confirmed the temporal stability of the site. Comparison between ground and satellite data at L-band are also presented here. Moreover multi-frequency analysis of data collected over this area is performed by using SMOS and AMSR-E data.
The contemporary legal status of Antarctica could soon become a polemical political issue due to the considerable natural resource wealth believed available there for exploitation. This paper examines those legal implications for Antarctica and the Southern Ocean which stem from the 1959 Antarctic Treaty vis-à-vis the emergent law for the sea as embodied in the 1982 UNCLOS III Convention.
Climatological features of NmF2 are investigated and compared using long-term observations among the Arctic and Antarctic stations of Tromso (69.6N, 19.2E; CGM:66.7N, 102.2E), Longyearbyen (78.2N, 16.0E; CGM: 75.4N, 110.7E) and Zhongshan (69.4S, 76.4E; CGM:74.7S, 96.9E). Interesting results are presented as follows: The maximum value of NmF2 mainly occurs at local noon (LN) at the auroral latitude station Tromso, but at magnetic noon (MN) at the cusp latitude station Longyearbyen and between local noon and magnetic noon at Zhongshan. There is another peak just before magnetic midnight at Longyearbyen in winter during solar maximum years. An enhancement of NmF2 is also detected during 21-01 UT in winter at Tromso. There are semi-annual anomaly at Tromso and normal variability at both Longyerabyen and Zhongshan during solar minimum years. During solar maximum years there is semi-annual anomaly for all three stations. The winter anomaly is evident at Tromso and Zhongshan, but does not exist at Longyearbyen. It is demonstrated that in addition to the solar radiation the magnetosphere-ionosphere coupling processes, such as particle precipitation and plasma convection, play a significant role in the high latitude ionosphere.
