- 摘要：The topography around the Taiwan Strait has been formed under the control of geological tectonism. However, modern oceanographic factors also play an important role in the developoment of topography and sedimentary structure in the strait. According to the characters of the topography (Fig.2) and its bottom materials (Fig.6)，the strait may basically be divided into two areas along the 24°N boundary line. The southern area is called the Taiwan Shoal, consisted of underwater dunes. Its sediments are composed of coarse to medium sands. To the south of the shoal the inner shelf topography is relatively flat and the outer shelf is rather steep. The sediments of the whole shelf are composed of fine sands, which are considered as relict sediment. The outer slope of the shelf is very steep with an average depth of 143 m. There are some biogenic materials and authigenic minerals in the slope sediments. The northern area of the strait (off the middle Fujian Province) consists of Wuqiu Channel near the shore, submeraged reefs and ridges in the middle and deep valleys in the east. Wuqiu Channel sediments are composed of fine sands?and silty sands, and in the east of channel sediments are clayey silts. The deep valleys might be a sedimentary area of terrigenous, relict sediments and marine sediments. To the further north of the strait the topography is relatively flat and sediments are composed of clays at the coastal area and gradually become fine-sand as relict sediments.关键词：TOPOGRAPHY AND SEDIME NT CHARACTERISTICS,TAIWAN STRAIT

发布时间：2023-04-28 - 摘要：Observations of the temperature and salinity microstructures with Mark-III CTD microprofiler were carried out by Institute of Oceanology, Academia Sinica in September 1985, along an oblique section through the Huanghai Cold Water Mass, the Qingdao Water Mass, and near by the Southern Huanghai Warm Current Water in the South Yellow Sea. In this paper, hydrological conditions along the section, including temperature T, Salinity S, conditional density σt Brunt-V?is?l? frequence N, geostrnphic current V, Richardson number Ri and so on are separately analysed according to the data obtained with Mark-III CTD. Microstructures of temperature and salinity along the oblique section are apparent and rich. Statistic characteristics of the temperature and salinity gradient layers, including the intension, thickness, and depth of upper and lower boundary of the gradient layers are represented in histogram and discussed. In addition, statistical parameters of the gradient layers such as the mean value, the mean-square deviation, the skewness S, and the kurtesis K are also calculated and analysed.关键词：HYDROLOGICAL CONDITION , MICROSTRUCTUR,OBLIQUE SECTION IN THE SOUTH YELLOW SEA

发布时间：2023-04-28 - 摘要：In this paper the distribution properties of NO3-, NO2-, NH4+ and PO43- in estuary of the Huanghe River (Yellow River) and its near waters, their removal processes in estuary and their relations with phytoplankton during April to November 1984 were discussed. High concentrations of inorganic N (particularly NO3-) are found in the estuarine water and low concentrations in the offcoast water and in the northwest region of Huanghe River estuary, indicating clearly that the high concenration of NO3- is from Huanghe River water. The distribution of PO43- in the estuary region of Huanghe River is consistent with NO3-, etc., but average concentration of PO43- is higher in the: water of northwest region of Huanghe River estuary where the exchange of PO43- is better between sediments and water. The distribution of the atomic ratio between total inorganic N and PO4-P is similar to NO2- and their changes of time and space is very large. The data show that the rich inorganic N and PO43- in the estuary region of Huanghe River are not the limiting factor for phytoplankton growth and it is possible that low concentration of NO3- in the northwest region of Huanghe River estuary sometimes limits the growth of phytoplankton. The distributions of three forms of inorganic N indicate that NO3- in the water of estuary region of Huanghe River and NH4+ in the water of northwest region of Huanghe River estuary are main forms of inorganic N respectively. The relationships of inorganic N and PO43- to salinity indicate that the removal processes of various inorganic N and PO43- in estuary vary in different time. The negative linear relative relationship of NO3- to S indicates that the concentration of NO3- is controlled by its dilution in seawater in the range of S surveyed. At the same time, the biological removal is evident for NO3- because a large quantity of phytoplankton is found there. In addition to the above two factors, other way for the removal of PO43- is possible because of the buffering action of suspensions and sediments of estuary. Therefore, the conservation of PO43- is worse than NO3-.关键词：INORGANIC NITROGEN,PHOSPHAET , ESTUARY OF THE HUANGHE RIVER

发布时间：2023-04-28 - 摘要：We had described (1981) crustaceous coralline algae, Lithothamnium pacificum (Fosl.) Fosl. and 2 other doubtful species from Huangxian, Shandong Province, known for their medicinal value as expectorant, cough remedy, antipyretic, etc. or known as “ Hai fu shi” in Chinese herbal pharmacopoeia. Further extensive collections made in other districts and a comparative study of their morphology with the use of SEM, made possible the distinguishing of 4 species of Lithothamnium from the North China Coasts, viz., 1. L. aculeiferum L. R. Mason, 2. L. fretense Fosl., 3. L. intermedium Kjellman, 4. L. pacificum (Fosl.) Fosl. Among them, L. aculeiferum and L. fretense are new to China. In this paper, L. pacificum is referred only to those distributed in the intertidal zone and L. pacificum sensu Zhang and Zhou is revised as L. fretense. Besides, L. fretense is quite similar to L. japonicum in their changeable outer morphology, though L. japonicum often becomes flat and often has well developed branches, the cover cells of L. japonicum are rather different from the former. More careful comparisons between L. japonicum and L. fretense are necessary in future. In the XIth International Seaweed Symposium, we had listed 6 species in the form of poster. Besides the above 4 species, other 2 species i.e. Lithothamnium sp. aff. fornicatum f. apiculata Fosl. and L. intermedium sensu Zhang and Zhou (1983) are doubtful after our carefully comparative study. L. intermedium which we refered to L. sp. sensu Zhang and Zhou (1983) has very peculiar characteristics, with sporic conceptacles most readily detached after discharge and seems to be only superficial，not always growing down into the frond. After comparing our specimens with the Japanese one sent kindly by Prof. Masaki, we refer this species to L. intermedium rather than to L. intermedium sensu Zhang and Zhou (1983), because our specimens have a close resemblance to the Japanese one of L. intermedium in both their inner structure of the thallus and their well developed basal crust, but differ from it in having branches repeatedly divided, which often form dense bundles and in the number of muciferous canals in each sporangial conceptacle, etc. Of course, type study is necessary in future. L. intermedium may account for 50－70% of “ Hai fu shi” in Huangxian, Shandong Province.关键词：NORTHERN CHINA LITHOTHAMNIUM

发布时间：2023-04-28 - 摘要：From 1866 to 1983, about 28 species of the articulated coralline algae were reported from China (see the list). Most of them, in general, were published in list without detailed descriptions morphologically or anatomically, and some only with a few localities indicated. Thus, it would be rather difficult to make a correct identification of certain species, and before the specimens from the similar localities were obtained or the original ones were examined, some? records could hardly be accepted with certainty. In this paper. 5 genera and 8 species belonging to Corallinoideae (Aresch,) Fosl. (Adey and Johansen, 1972; Johansen, 1976) with their anatomical details and concrete localities in China are described. The specimens used for this study were collected by members of the Institute of Oceanology, Academia Sinica and the present authors during 1949-1984, and by Prof. C. K. Tseng during 1933一1941. Among them. Cheilosporum jungermannioides Rupr. was already recorded from Taiwan Province (Shen and Fan, 1950), Corallina sessilis Yendo and Jania ungulata Yendo f. brevior Yendo from Hong Kong, (Lee, 1965), Jania rubens (L.) Lamx. is new to China; other 4 species, namely, Bossiella cretacea (P. et R.) Johansen, Jania crassa Lamx., Marginisporum crassissimum (Yendo) Ganesan, and M. aberrans (Yendo) Johansen et Chihara were reported by the present authors in “ Common Seaweeds of China" for the Chinese marine flora for the first time. We are much interested in the Genus Marginisporum which was originally regarded as being endemic to Japan, but recently two species of the genus, i.e., M. crassissimum (Yendo) Ganesan and M. aberrans (Yendo) Johansen et Chihara, were also found of frequent occurrence on the coasts of Zhejiang or Fujian Provinces,, China. As pointed out by Johansen (1969), the marginal and lateral conceptacles with essentially straight medullary filaments characterized by Marginisporum, are also present in the Chinese specimens. Even though, the conceptacle types in Marginisporum, whether marginal or lateral, are not always very clear. Sometimes, margina1. conceptac1es appearing axial, cortical ones appearing marginal after maturity (Johansen, 1981). Based upon Yendo (1902a)， Segawa (194la, 194lb) and our anatomic and distributional investigations on the above two species of Marginisporum from Japan and China, we think it would. be more reasonable to combine the closely related species Amphiroa aberrans Yendo together with A. crassissima Yendo and A. declinata Yendo into the genus. Marginisporum.关键词：ARTICULATED CORALLINE ALGAE,CHINA

发布时间：2023-04-28 - 摘要：In May, 1958 and February 1961, we carried out investigations from off shore waters of southeast Hainan Island between latitudes 16°一22°N, longitudes 110°一115°E with the purpose of collecting acantharian specimens. All the samples from forty seven stations of this area were examined. Forty acantharian cysts of different shapes had been found from six stations (fig. 1). According to our observation and previously published information, from the morphological point of view, there seems to be three phases during the process of cyst formation: Prophase一一The central structure of spines in cyst is not separated yet. Metaphase一一The central structure of spines in cyst is already separated but more or less still retaining some structure characteristic of spines. Anaphase一一The spines in the cyst have all disappeared. According to their shape and the structural characteristics of spines, these cysts may be divided into two groups: Group I Includes all the cyst in the prophase stage and a few cysts in the metaphase stage. They could be identified to genus but not to species. It includes 10 formas under five genera.关键词：ACANTHARIAN CYSTS ,SOUTH CHINA SEA

发布时间：2023-04-28 - 摘要：Ecdysteroid concentration determined by RIA in certain organs (hepatopancreas, hemolymph, eyestalk, muscle, heart, etc) of prawn (Penaeus orientalis) demonstrated that the concentration of ecdysteroid in prawn collected from Jiaozhou Bay, Qingdao in September and October is generally higher than that in the matured prawn collected in May. The concentration of ecdysteroid in eyestalk of the prawn during the moulting period is the highest. The ecdysteroid concentrations in the organs excepting muscle during the intermoult period increased gradually, and reached the highest during the moulting period. This result suggests that the activity of eyestalk Y-organ changes within moult cycle. The present experiment shows that concentration of ecdysteroid in the inclusions of midgut is 2.27一28.36 pg/mg, which suggests that there is rich ecdysteroid in the food ingested by prawn from natural sea.关键词：PENAEUS ORIENTALIS, ECDYSTEROID CONCENTRATION

发布时间：2023-04-28 - 摘要：The present paper deals with the Mysidacea fauna of the North China waters ——the wes tern part of Yellow Sea and the Bohai Sea. The materials studied were collected by the Institute of Oceanology and the Institute of Zoology, Academia Sinica, from shallow waters off the North China coasts during the past thirty years. Through the present study the authors found that the mysid fauna of the northern part of China seas is comparatively poor in species, but several species of this group, e. g. Neomysis awatschensis, N. japonicus, Acanthomysis longirostris, etc., are very abundantly distributed in shallow seas, particularly in coastal waters of low salinity and estuaries of rivers, and are of economic importance in local fisheries. They are utilized and sold in fish market freshly or as shrimp paste as nutrient food for human consumption .as well as for cultivated shrimps. A total of 16 species belonging to 3 subfamilies and 8 genera of the Family Mysidae were identified, of which 2 are described as new, namely Pseudomma brevicaudum Shen et Liu sp. nov. and Acanthomysis sheni Wang et Liu, sp. nov. The latter species is named in honour of the founder of Chinese carcinology, the late Professor C. J. Shen. The type materials of the new species are deposited in the Institute of Oceanology, Academia Sinica, Qingdao.关键词：MYSIDACEA,WATERS OFF THE NORTH CHINA COASTS

发布时间：2023-04-28 - 摘要：This paper presents the results of ecological study of the macrobenthic fauna in the Huanghe River estuary and adjacent waters. The materials for study were collected during eight cruises in April-November 1984. The species composition and distribution of biomass and density was described and discussed. Relative abundance of Echinodermata is higher in area northern to the river mouth, but that of Mollusca is higher in the southern area. Polychaeta was found everywhere in the explored region, but Crustacea was abundantly found in area northern to the river mouth. The distribution of biomass and density is extremely uneven, but the areas of high biomass and high density were basically similar, both in Laizhou Bay. The highest record of biomass occured in July, being ?X＝ 50.76g m-2, but the lowest was in November, being ?X＝ 25.83g m-2. The highest record of density was in November, being ?X＝622 ind. m-2, but the lowest in August, being ?X＝304 ind. m-2. Dominant group of the benthic fauna in this region was Mollusca, particularly Musculus senhonsei. In this paper, the seasonal change in abundance (biomass and density) of Musculus senhonsei was described.关键词：ECOLOGICAL CHARACTERISTICS ,MACROBENTHOS ,HUANGHE RIVER ESTUARY
