Abstract:
Based on the ray theory of waves and the linear model of sea waves, a joint distribution of periods and heights is derived. The theoretical expression has the same merits as those of Lon-guet-Higgins', but the wave height distribution is still Raylei...

Abstract:
The daily weather maps of the 850 hPa level and the monthly mean wind maps of tropical regions published by ECMWF are utilized to study the cross-eguatorial currents. It is found out that there are 3 branches of the cross-equatorial current in the ar...

Abstract:
Phytoplankton samples were collected bi-weekly by towing a 20 μm mesh net in the Indian River Lagoon from January to August, 1985. Two-way ANOVA and T-method was used in analyzing data. Identified were 145 species of phytoplankton including 89 specie...
