Pagination or Media Count:
This report consists of two independent parts. The first part addresses the interannual variability in the Arctic Ocean. The analysis of long-term variations in the water temperature and salinity from the beginning of the 20th century until present, has been conducted with the use of all available data of CTD measurements in different regions of the Arctic Basin, and up-to-date climatology data which represents the mean hydrologic fields. The second part of this report considers the results of processing and analysis of the signals transmitted during the Transarctic Acoustic Propagation experiment from the ice camp TURPAN and received at the ice camp NARWHAL. The main goal of this study is to determine the propagation loss of individual acoustic modes in the signals transmitted across the Arctic Basin to the Lincoln Sea.
