Particulate matter levels are rapidly increasing daily, and this can affect human health. Therefore, air pollutant emissions from sea vessels require management. This study evaluates the status of air pollutants, focusing on air pollutant emissions from the vessels of the Korea Coast Guard (KCG), and proposes national management measures to reduce emissions. According to a report recently released (2018) by the National Institute of Environmental Research (NIER), emissions from vessels constituted 6.4 % of the total domestic emissions, including 13.1 % NO_x, 10.9 % SO_x, and 9.6 % particulate matter (PM10/PM2.5). Among the rates of pollutant emission from vessels, the emission rates of domestic and overseas cargo vessels were the highest (50.6 %); the ratio of fishing boats was 42.6 %. With respect to jurisdictional sea area, 44.1 % of the emissions are from the south sea, including the Busan and Ulsan ports, and 24.8 % of the emissions are from the west sea, including the Gwangyang and Yeosu ports. The KCG inspects boarding lines to manage emission conditions and regulate air pollutant emissions, but it takes time and effort to operate various discharge devices and measure fuel oil standards. In addition, owing to busy ship schedules, inspection documents are limited in terms of management. Therefore, to reduce the air pollutant emissions of such vessels, regulations will be strengthened to check for air pollutants, and a monitoring system based on actual field data using KCG patrol ships will be established, for each sea area, to manage the emissions of such vessels. Furthermore, there is a need for technological development and institutional support for the introduction of environmentally friendly vessels.

세계 해양환경의 보전을 위하여 설립된 UN 기구인 국제해사기구(IMO)에서는 해양환경 오염물질 등에 대한 규제강화를 위하여 최근 새로운 해양환경협약의 채택 및 발효를 강력히 추진해 오고 있다. IMO의 국제협약은 선박이라는 효과적인 제어수단을 통하여 가장 강력한 통제력을 갖는 협약으로 세계 모든 해양국의 해양환경에 관한 국제법의 성격을 띄고 있다. 구속력이 강력한 만큼 변화되는 국제협약에 의해 새롭게 창출되는 해양환경시장의 규모가 엄청나므로 당사국들이 서로 자국의 이익을 위해 올인하는 전형적인 그린라운드의 양상을 띄고 있는 현실이다. 우리나라는 국제해사기구의 A그룹 이사국이며 아울러 세계 제일의 조선대국, 또한 세계 6위의 해양대국으로서의 국제적인 위상을 감안할 때 해양환경 보호를 위하여 현재 발효되고 추진 중에 있는 협약에 대한 연구와 효과적 대처를 하여야 함은 물론 우리나라 조선, 해양산업이 보호되고 나아가 이익이 창출될 수 있는 방향으로 모든 국제협약이 이루어지게 노력해야할 것이다. 이 논문은 해양관련 환경규제 협약인 Marpol 73/78 협약, 선박의 유해방오도료 사용규제협약, 평형수 배출규제협약, 선박으로부터 오수에 의한 오염방지를 위한 협약, 대기오염방지협약 등의 주요 현안을 파악하고 분석하여 이에 따른 현실적인 대응책을 제시하고자 한다.

RADARSAT is one of many possible data sources that can play an important role in marine surveillance including ship detection because radar sensors have the two primary advantages: all-weather and day or night imaging. However, atmospheric effects on SAR imaging can not be bypassed and any remote sensing image has various geometric distortions. In this study, radiometric and geometric calibrations for RADARSAT/SAR data are tried using SGX products georeferenced as level 1. For radiometric calibration, information on the magnitude of the radar backscatter coefficient of the imaged terrain is extracted from the processed image data. Conversion method of the pixel DNs to beta nought and sigma nought is also investigated Finally, automatic geometric calibration based on the header file is compared to a marine chart.

To search out the characteristics of the lower and the upper atmospheric vertical structure, we selected the island(Oeyoundori Ochun-myen Poryeng city Chung-Nam) as an observation site, which is thought to represent the characteristics of ocean well, and observed the vertical structure of the atmosphere by Radiosonde. By using the results of the observation, we analyzed the changes of relative humidity(RH), temperature and wind when the cyclone and the anticyclone passed and compared the results in case of each event. To compare the vertical structure of the ocean atmosphere with those of the continent, we analyzed the values observed with using Radiosonde at Osan site.Through this study, we found that relative humidity changed as the cyclone and the anticyclone passed. That is, when the cyclone came, RH increased first in the upper atmosphere than in the lower and when the high came, RH in the upper decreased sharply to 10%. And the variations of relative humidity in ocean are bigger than those in continent. In the future, we plan to find out the relation between the vapor water in ocean and continent seasonally and daily through the observation in ocean and continent at same time.

남극은 인위적인 오염원에서 멀리 떨어져 있고 가장 깨끗한 환경을 유지하고 있기 때문에 배경환경으로써 평가되어져 왔다. 따라서 ice core 안에서, 시간에 따른 용해성 이온종들의 조성 변화는 지구 대기조성 변화를 나타내는 것으로 알려져있다. 특히 ice cores나 눈 속에 존재하는 황산염과 MSA(Methan Sulfonic Acid)는 해양생물의 활동도 변화론 연구하는데 있어 유용한 도구를 제공해주며, 그것은 과거 기상적 변화와 관련이 있다.(중략)

돗대기새우류(Leptochela sp.)는 전 세계적으로 2아속 12종이 분포하고 있으며 이중7종이 인도태평양 해역에 분포하고 있다. 우리나라 연안해역에서는 돗대기새우 (L.gracilis)와 둥근돗대기새우(L. sydniensis) 2종이 보고되고 있으며 특히 봄과 가을에 대량 출현한다. 돗대기 새우는 젓새우류와 혼획되어 어획되며 서남 해역에 어가의 주소득원이 되고 있다. 지금까지 보고된 연구는 형태학적 분류 (Chace, 1976), 성장 (Park and Lee, 1995)과 2차 성징의 특성 (Park, 1984)에 관한 연구 등이 있다.
