Available in PDF, EPUB and Kindle. Book excerpt: Sea ice is one of the most important components of Earth’s cryosphere that regulates heat flow between the ocean and atmosphere, impacts water cycles and oceanic currents due to salt transport during the melt and freeze seasons, provides a natural habitat for many life forms, and affects global transportation. Remote sensing of sea ice has become more important than ever given the substantial reduction in sea ice extent in the Arctic in recent decades. A major advantage of remote sensing for sea ice studies is the continuous monitoring available from space that eliminates the need for expensive and difficult in-situ measurements. Although satellite-borne passive microwave radiometer observations of sea ice have been performed since the 1970s, significant challenges remain. Radiometer measurements at frequencies greater than approximately 19 GHz can detect sea ice concentration and extent but are impacted by clouds. L-band radiometers operating at 1.4 GHz have been shown to successfully estimate sea ice thicknesses up to ~1.5 m; however, thickness sensing performance is limited by the penetration depth in sea ice at this signal frequency. Radiometers operating at lower frequencies have not been used on satellites to date due to the strong man-made radio frequency interference (RFI) present at frequencies less than 1.4 GHz. The Ultra-Wideband Software-defined Microwave Radiometer (UWBRAD) was developed at The Ohio State University to observe thermal emissions in the presence of RFI. The instrument performs RFI detection and mitigation algorithms at multiple frequency channels from 0.5 – 2.0 GHz. As a result, UWBRAD is capable of retrieving sea ice thickness for ice thicknesses greater than 1.5 m due to its lower operating frequencies. In addition, the measurement of sea ice thermal emissions over the 0.5-2 GHz spectrum reveals additional information on ice characteristics and can allow the simultaneous retrieval of sea ice thickness and salinity. This dissertation examines the remote sensing of sea ice through wideband microwave radiometry. Sea ice thermal emissions are modeled for UWBRAD’s 0.5-2 GHz frequency spectrum and compared with measurements from validation campaigns. A retrieval process is also described to characterize ice thickness and salinity. Results from the two successful campaigns in which the instrument was operated in Greenland and in the Arctic are demonstrated. In addition, wideband retrieval performance is further investigated to explore the effect of available ancillary data, and Arctic scale retrieval simulations are described that provide additional insights to guide future wideband radiometer remote sensing missions.

Book excerpt: "Techniques for gathering data by remote sensors on satellites utilized for sea ice research are summarized. Measurement of brightness temperatures by a passive microwave imager converted to maps of total sea ice concentration and to the areal fractions covered by first year and multiyear ice are described. Several ancillary observations, especially by means of automatic data buoys and submarines equipped with upward looking sonars, are needed to improve the validation and interpretation of satellite data. The design and performance characteristics of the Navy's Special Sensor Microwave Imager, expected to be in orbit in late 1985, are described. It is recommended that data from that instrument be processed to a form suitable for research applications and archived in a readily accessible form. The sea ice data products required for research purposes are described and recommendations for their archival and distribution to the scientific community are presented."--NTIS abstract.

This book was released on 2006-11-30 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote Sensing of Sea Ice in the Northern Sea Route: Studies and Applications initially provides a history of the Northern Sea Route as an important strategic transport route for supporting the northern regions of Russia and cargo transportation between Europe and the Northern Pacific Basin. The authors then describe sea ice conditions in the Eurasian Arctic Seas and, using microwave satellite data, provide a detailed analysis of difficult sea ice conditions. Remote sensing techniques and the basic principles of SAR image formation are described, as well as the major satellite radar systems used for ice studies in the Arctic. The authors take a good look at the use of sensing equipment in experiments, including the ICE WATCH project used for monitoring the Northern Sea Route. The possibilities of using SAR remote sensing for ice navigation in the Northern Sea Route is also detailed, analysing techniques of automatic image processing and interpretation. A study is provided of regional drifting ice, fast ice and river ice in the coastal areas of the Arctic Seas. The book concludes with a review of the practical experience using SAR images for supporting navigation and offshore industrial activity, based on a series of experiments conducted with the Murmansk Shipping Company on board nuclear icebreakers.
