Final Report for Office of Naval Research Contract N00014-75-C-0187,
Abstract
This report consists of the following three manuscripts: (1) Underwater Acoustic Studies of the Chukchi Sea (Published in the Proceedings of the Ultrasonics International 1975 Conference, London, 1975, p249-272; (2) Aspects of Water Column Primary Productivity in the Chukehi Sea during Summer; and (3) Bioacoustic Studies in the Chukchi Sea. The first manuscript describes the acoustic aspect of the studies in the Chukchi Sea during July 1974. Analysis of the data reveals scattering strengths as great as -60 dB (re 1/m) at 105 kHz, and the echograms indicated intense biological activity, at least during the summer months. The second manuscript quantitatively describes the phytoplankton productivity and the related biological processes extant in the Chukchi Sea during summer. The data on selected biological, chemical and physical variables, obtained concurrently with primary productivity measurements, are statistically analyzed. In addition, factor analysis is used to investigate the covariation in the data. The third summarizes the overall contract effort and is a reprint from the Arctic bulletin, v2 n7 p8-10 1975.
