In an attempt to make oceanophysical observations of the coastal areas of Mogpo and Soheugsando 150km away from the southwestern coast, the periodical function formula of the surface-water temperature of the two areas was obtained by applying Fourier's processing theory and by examining and analyzing the records of the past 41 years in Mogpo and of the past 46 years in Soheugsando based on the original observation record of "Oceanographic data of the shore station." Variations of temperature were compared as well as the year-average surface temperatures and air temperatures. Their minimum value, minimum water temperature value, ten-days minimum value, and specific gravity were appeared to be low around Mogpo and the maximum value, yearly difference and daily variation appeared, on the reverse, to be high around Mpgpo. These facts are a energy reaches the earth. The conclusion is that since Mogpo is a coastal area with shallow water it has been greatly influenced by the radiation energy of the land specific heat.

新安海域의 海洋學的 特性에 關한 硏究

曺炷煥,金容熙 조선대학교 기초과학연구소 1984 自然科學硏究 Vol.7 No.1

The purpose of this paper lies in collecting fundamental data which can contribute to basic studies on oceanograph and activities in fishery and marine industry by examining the oceanographical characteristics of the Shin-an sea area. To collect the fundamental data, the author examined oceanographical elements such as temperature, precipitation, water temperature, salinity, dissolved oxygen, transparency, pH, and nutruents in the Shin-an sea area, in February, May, September, and November in 1981 and 1982. The result of this study is as follows. The transparency and water temperature are high in summer when air temperature is high and the amount of precipitation is large, and low in winter when the amount of precipitation is small. This phenomenon shows that water temperature increases in proportion to air temperature. The precipitation in September 1981 was 548.2mm, which is the largest amount. Salinity is 29.95‰ lowest in September because of the influx of lots of land water to the Shin-an sea area. And it is 33.62‰ highest in Fevruary. pH was low in September when air temperature and water temperature are high and the amount of precipitation is small, but a little high in spring and winter. But the range of pH proves to be narrow and pH of the Shin-an sea area is almost the same as the average pH of sea water. NO^-_2-N, PO^-_4-P and a nutrient prevail in September when there is a large amount of precipitation. This phenomenon seems to have resulted from the influx of large amounts of organic matter as well as a large amount of precipitation from the land. During studying the oceanographical elements. the amount of NO^-_2-N is not changed according to the change of season : that is, there is no correlation between the amount of NO^-_2-N and oceanographical elements. But PO^-_4-P appeared in the largest amount in winter and in the smallest amount in spring. Dissolved oxygen is 7.20cc/ℓ in February which is the highest amount, and 4.12cc/ℓ in September, the lowest amount. This phenomenon seems to have resulted from the consumption of large amount of dissolved oxygen that is related to oxidization of organic matter and the breathing of plants and animals.

The purpose of this study is analyze the physical and chemical characteristics(water temperature, salinity, pH, dissolved oxygen, COD, phosphate, suspended solids, dissolved inorganic nitrogen) of the Southwestern coastal area of Korea. An investigation on oceanographical conditions of seawater in five sites (Youngkwang, Mokpo, Jindo, Wando and Dujrang bay) was carried out during from 1995 to 1996. These sea area showed a wide variation with time, place and season. These factors are very important for the inhabitance and laying eggs of aquatic life. The sea adiacent the coast of Wando is comparatively pure as yet. But recently, on account of the increasing pollution by materials flowing from islands, the environment of squatic life gradually worsen. From the data collected in this research it is possible to conclude that a countermeasure for the preservation of oceanic environment with a purpose of decreasing the level of pollutants which affects the ocean in need.

錦江河口둑 建設 前後의 海洋還境 變化에 관한 硏究

曺炷煥,申仁鉉 조선대학교 기초과학연구소 1992 自然科學硏究 Vol.15 No.1

To analyze the variation of the marine environments on Kum River estuary before and after the enclosure of the dam which physical and chemical surveys were made from February, 1986 to June, 1990. The results were as follows ; 1. Water temperatures were 0.20-29.00℃ before the estuary enclosure of the dam, but 1.99∼26.87℃ after that through the years. Comparing with before the enclosure of the dam, it was high in winter and low in summer. 2. Salinity was lower after than before the enclosure of the dam. Specially it was distinguishably low on St. 1,2 by the fresh water discharge in summer. 3. Dissolved oxygen content was decreased after the enclosure of the dam, but it was rather supersaturated partially in the plankton-rich area of the inner bay. 4. pH value was higher after than before the enclosure of the dam, but it was the lowest in summer with the fresh water discharge. 5. COD was gradually increased after the enclosure of the dam and it was high in summer specially It was the reason why the inflow of city foul water was increase and the exchange ability of sea water became low and stagnated with the decrease of tidal current by the enclosure of dam. 6. TSS was greatly decreased after the enclosure of the dam and transparency was distinguishably increased. 7. Ammoniac Nitrogen among the nutritious saline was highly increased after the enclosure of the dam comparing the before. On the contrary, Phosphate-Phosphorus, Nitrite-Nitrogen and Nitrate-Nitrogen were reduced. This phenomenon was low in the closure area which was enrich to the propagation of phyto-plankton with fresh water in spring. From the above results, I feared the change of maring circumstances since that the enclosure of the dam in Kum River estuary did not weaken only the flow of the river and the tidal current, but mede the stagnated water area and the exchange ability of open sea water was low. Thus, it was required the reasonable counter plan to prevent the inflow of industrial pollution for the adequate circumstances.

The results from investigation for the physical, chemical and biological marine environments during the period from February 1989 to November 1990 in the Wando coastal areas are as follows: 1. The water temperature appeared high in proportion to a amount of diural sun rays and air temperature. 2. The salinity appeared differently every season by a amount of precipitation. 3. The distribution of pH was settled, and the degree of acidity apperared relatively high in the area where the river waters flows. 4. The dissolved oxygen was low in summer season, but high in winter. 5. The distribution of the chemical oxygen demand was distributed irregularly every season. 6. The suspended materials appeared remarkably high on St.1 in 1990. 7. The concentration of the phosphate-phosphorous is higher in river waters than in sea waters, and the phosphate-phosphorous in sea waters was mostly flowed from lands. 8. The concentration of the dissolved inorganic nitrogen appeared high in autumn when nitrite-nitrogen and nitrate-nitrogen is more concentrated. 9. The relative relationship between phosphate-phosphorous and dissolved inorganic nitrogen appeared higher comparatively in 1990 than in 1989. After all. our investigation suggests that the physical, chemical character brings about an abnormal variation of the marine ecosystem, and obstructs the birth and breeding of the submarine livings. Therefore, we must draw up divers shemes for the preservation of the quality of coast water, and concentrate our efforts on doing away with factors of all marine pollution which spread rapidly in proportion to the industrial development.

新安海域의 海洋學的 特性에 관한 硏究

曺炷煥,姜大連 조선대학교 기초과학연구소 1994 自然科學硏究 Vol.17 No.1

The purpose of this study is to investigate and analyze the physical and chemical characteristics (water temperature, salinity, pH, DO, COD, transparency, solid solution, and nutrient) of the Shinan sea area extending from February to November in 1992 and to contribute to the protection of sea ecosystem and sea environment through research on sea pollution. The following are the results. The water temperature of the continental side sea was lower in winter and higher in summer than that of the island side sea. This seems to have resulted from the difference of specific heat between in land and in sea. Salinity was highest in April and lowest in August. This may be viewed in the way that much precipication and fluctuation of land water from the mouth of Mokpo in the rainy season, summer, have influenced on the salinity of the above sea area. The range of pH proved to be rather high in summer. This seems to have resulted from the features of atmosphere and land and water distribution of this area. DO was highest in February and lowest in August on account of the influence of water temperature and activities of marine inhabitants. But COD was highest in August and lowest in April. This also had a close relation to water temperature and activities of marine inhabitants. Judging from the standard amount of inhabitant environment of marine organisms, 2 mg/l, the above-mentioned area was found rather clean. Transparency was high in summer and low in winter. This may be viewed in the way that the shallow soundings and monsoon had an influence on the spout of marine deposits such as silt and clay. Solid solution was high in spring and winter. The correlation coefficient to the transparency was r=-0.927 in the continental side sea and r=-0.845 in the island side sea. This showed reverse distribution. PO4-P was high in spring and winter and low in summer and autumn. This resulted from the fact that the amount of consumption decreased in winter on account of the weakening of plankton multiplication, while the amount of supply increased on account of the decomposition of the animal dead bodies. NH_4-N was high in spring, when all living creatures are enlivened. NO_2-N and NO_3-N was high in autumn owing to the cycle process of nitrate. DIN was high in autumn and winter and the Shinan sea area was found one of the malnourished area in total nitrogen quantity The correlation coefficient between PO_4-P and DIN in the continental side sea was r=0.368 on the surface and r=0.821 at the bottom, while that in the island side sea was r=0.6833 on the surface and r=0.895 at the bottom. This showed that the island side sea was higher and more stable in correlation than the continental side sea. According to the above results, the author found that the Shinan sea area was one of the malnourished and rather clean sea area and was proper for an ecosystem environment.

海洋學的 要素의 變化가 김 生産에 미치는 影響

曺炷煥,李元鎭 조선대학교 기초과학연구소 1986 自然科學硏究 Vol.9 No.1

The aim of this paper is to study and analyze the physical, chemical and biological elements in Hampyeong bay, and the Aphai coastal area in Sinan on the early growing period August-December for the purpose examing what caused the laver production difficiency in Hampyeong bay in 1983 and 1984. In this study these stations were established in Hampyeong bay, two stations in Aphai coastal area, and water temperature, salinity, dissolved oxygen, pH, chemical oxygen demand, PO_4-P, NH_4-N, NO_2-N, NO_3-N and plankton were investigated. The laver crop was poor in this period for the following reasons; the tide currents interfered by the laver crop to exceed its productive capacity in limited fishing sea area; infant weeds suffered photo-oxidation phenomena by the continuously unusual high temperature of the early periods and excessive sunlight; nutritious salt water was consumed by the excessive propagation of phyto-plankton and seaweeds; the decompose phenomena by the sedimentation of animal and plant remains. The reason why these phenomena occurred is that sea water interchange capacity is limited in the Hampyeong bay itself, and even if seawater is interchanged, it is blocked in the narrow water course of the neighbouring sea area, and the original seawater comes back again in the bay, mixing with outer seawater at the time of the tide. In particular, because a large quantity of laver was cultivated in the open outside Hampyeong bay during 1982 and 1983, the influx of open sea water caused the speed of a current to decrease sharply. For these reasons I consider Hampyeong bay became a sluggish water area.
