Estimating Geoacoustic Properties of Surficial Sediments in the North Mien-Hua Canyon Region With a Chirp Sonar Profiler

The Rimouski shelf is a smooth-surfaced, gently sloping platform which gives way to the north to a steep, sometimes irregular margin of the Laurentian Trough. The surficial sediments are sandy and change rapidly over short distances particularly in areas close to the shore. A zone of well-sorted medium sands, littered in places with gravel, and surrounded by bands of finer, more poorly sorted sediment occupies the western half of the shelf. The central part of the shelf is also banded but fine-grained sediment is more abundant. Sand deposits reappear on the eastern edge of the study area, while uniform muds occur over the slope. These surface deposits are thin and appear to be related to modern shelf currents, ice rafting from the shore, and local sources of mud. Below the surface the deposits become more sandy and are often in sharp contact with a dense clay. The latter is correlated with the Goldthwait Sea clays of 9–12000 years BP. Available information suggests that the Goldthwait Sea regression continued past the present shorelines to permit the emplacement of the sandy deposits and then transgressed once more to about the present sea level during the last 9000 years.

The Right

SummaryRecently, there has been a proliferation of international agreements imposing minimum standards on states in respect of their treatment of foreign investors and allowing investors to initiate dispute settlement proceedings where a state violates these standards. Of greatest significance to Canada is Chapter 11 of the North American Free Trade Agreement, which provides both standards for state behaviour and the right to initiate binding arbitration. Since 1996, four cases have been brought under Chapter 11. This note describes the Chapter 11 process and suggests some of the issues that may arise as it is increasingly resorted to by investors.

Cyclic Variations

AbstractLong-term cyclic variations in the distribution of prominences and intensities of green (530.3 nm) and red (637.4 nm) coronal emission lines over solar cycles 18–23 are presented. Polar prominence branches will reach the poles at different epochs in cycle 23: the north branch at the beginning in 2002 and the south branch a year later (2003), respectively. The local maxima of intensities in the green line show both poleward- and equatorward-migrating branches. The poleward branches will reach the poles around cycle maxima like prominences, while the equatorward branches show a duration of 18 years and will end in cycle minima (2007). The red corona shows mostly equatorward branches. The possibility that these branches begin to develop at high latitudes in the preceding cycles cannot be excluded.
