Probability distribution of surface slope for nonlinear random sea waves and calculation of whitecap coverage
Song Jinbao, Wu Kejian, Xu Delun, Sun Fu
1997, (2): 141-148.
Abstract:
Based on the nonlinear model of two-dimensional random sea waves, a statistical distribution of wave surface slope exact to the third order is derived by using the expansion of the characteristic function and direct calculations of each order moment....
Outer frequency spectrum of sea waves and its equilibrium range
Wu Kejian, Song Jinbao, Zhao Dongliang, Sun Fu
1997, (2): 149-155.
Abstract:
The present paper defines the generalized apparent energy distribution and derives the analytical form of the so-called generalized outer frequency spectrum or nth order apparent frequency spectrum. It is shown that the generalized outer frequency sp...
Evolutions of flow field and heat exchange on equatorial Pacific surface in El Nino-La Nina cycle
Ma Kaiyu, Yao Huadong, Lin Zhenshen, Chao Junwu
1997, (2): 157-170.
Abstract:
Abstract-In this paper, the monthly averages and deviations of temperature, pressure, tonal wind, specific humidity, cloud rover and the components of heat budget have been remputed on the equatorial (5°S-3°N) Pacific surface (EPS) based on the 2*×2*...
A simulation of radiation imagery for ocean color satellite
Pan Delu, Roland Doerffer, Mao Tianming, Li Shujing
1997, (2): 171-191.
Abstract:
The ocean color satellite is mainly applied to measure the water constituents such as chlorophyll, suspended material and yellow substance. The leaving water radiance is very small part of the total radiance arrival at the sensor about 3%-15%,and dep...
Remote sensing composite information of Nansha reef's closed atoll and model of its spatial structur evolution——Ⅱ
Wang Yanfeng, Liu Baoyin
1997, (2): 193-199.
Abstract:
Based on the Nansha Islands' closed atoll conception-remote sensing system in Part Ⅰ,through the solution of the information function value and isostatic value of closed and quasi-closed atoll, and by using topological analysis on growth form and the...
Responses of carbon dioxide in western tropical Pacific to 1991~1993 ENSO event
Ma Liming
1997, (2): 201-214.
Abstract:
On the basis of the data of the partial pressure of CO2 (PCO2)and the concentration of the total dissolved CO2(TCO2) in surface water during the expeditions in Nov.-Dec. 1991, the world ocean circulation experiment (WOCE) and Oct. 1992-Mar. 1993, the...
Isozyme changes during larval development of Penaeus chinensis
Zhang Zhifeng, Ma Yingjie, Liao Chengyi, Wang Hailin
1997, (2): 215-224.
Abstract:
Isozyme changes during early development of Penaeus chinensis are described for six enzymes (EST, AMY MDH, GDH, Gd and LDH) by means of polyacrylamide gel vertical plate electrophoresis. The results show that the number of isozymes varies considerabl...
Types and characters of sub-bottom acoustic reflection in eastern part of Bohai Sea
Wang Kuiyang, Liu Zhenxia, Xia Dongxing
1997, (2): 225-237.
Abstract:
High-resolution sub-bottom profiler has revealed sedimental strata and environments in the eastern part of the Bohai Sea since the Late Pleistocene. According to the characters of acoustic reflection and seismic-stratigraphic principle, some classifi...
Some problems on dynamical sedimentology in sea area near Huanghe Seaport
Zang Qiyun
1997, (2): 239-248.
Abstract:
In this paper, two problems on dynamical sedimentology in the sea area near the Huanghe(Yellow) River Seaport are studied. Firstly, with synchronously observed data of bed-load trap and winds, starting and transporting dynamical mechanism of sediment...
Studies on morphocytology of Planktoniella and correction of nomenclature of Valdiviella formosa (Schimper ex Karsten) Karsten
Qian Shuben, Wang Wei
1997, (2): 249-258.
Abstract:
Based on the morphocytological studies on Planktoreiella,two species of the genus, p. sol Schütt and p. formosa (Qian et Wang) are recorded in China's seas. The renaming of the latter species is based on a careful study on Valdiuella formosa (Schimpe...
