Giant comet marks up to 135-m long and 30-m wide were detected 130 km northeast of Durban (South Africa) during a side-scan sonar survey. The high width-length ratio of 1:4.5, in contrast to ratios of 1:33 observed elsewhere, is attributed to lateral coalescence of adjacent tails. The marks are interpreted as erosional features formed in the wake of large obstacles in an area continuously exposed to the strong geostrophic flow of the Agulhas Current.

85:5167 Miller, R.G. and R.K. O'Nions, 1985. Source of Precambrian chemical and elastic sediments. Nature, Lond, 314(6009):325-330. Nd isotope composition of surviving Archaean sediments provides no evidence for the existence of pre-4000-Myr continental crust. Either the amounts of such crust were trivial or it was destroyed substantially by 3800 Myr ago. Nd in major Precambrian banded iron formations was supplied largely by continental weathering; in this respect the water masses in which they formed were analogous to modern oceans.

SONCHES--a subject oriented, task-related, modular and interactive simulation system--is presented as the framework for model building and evaluation, forecasting, testing of hypotheses, and control design. The main emphasis of this paper is toward technical rather than ecological details. Central Inst. for Cybernetics and Info. Proc., G.D.R.

Model., 26(1-2):103-113.
Tests of a 15-component model indicate its capability to describe and predict the general dynamics of algae and nutrients, sufficient for purposes of
water management. Special interest has been paid to the critical analysis of differences between simulations and field data of several components of the model. Inst. of Geogr. and Geoecol., G.D.R. Acad. of Sci., Berlin, DRG.

Such a unique faunistic assemblage has never before been reported for Mexican Pacific coastal lagoons. Univ. Nac.
