The present study was carried out to discuss the suitability of the criterion for the determination of the on-water oil removal resource requirement in Korea by comparison with the US criterion. According to the present criterion in Korea, the on-water response operation against the worst case discharge assuming the oil spillage of 60,000 ton from the accident of DWT 300,000 tanker requires the oil recovery capacity of 19,425 kl/hr (on-water recovery volume 20,000 ton). Under the US criterion, the recovery capacity of 16,667 kl/hr is required to respond to oil spill accident of the worst case discharge from the DWT 300,000 tanker. The result shows that resource requirement from the Korean criterion is 16% higher than US criterion, indicating that thc Korean criterion is reasonable

This is a brief report on the development of a system which provides fishing vessels with a real-time key information that can direct to regions of high fish density. Water temperature and Plankton distribution are the base parameters and various public information have been examined and summarized. The suface water temperature can be obtained from NOAA's high resolution infrared data base and the vertical water temperature can be obtained from TAO/TRITON's buoy near the equator and ARGOS's drifting buoy covering wider Pacific ocean. MODIS's data is also utilized for sea color information. A model data format is proposed and a few examples are demonstrated.

The circulation of sea water was simulated by two dimensional tide model using the main four tidal components and permanent current driven by inflow/outflow across open boundaries. According to the residt of tide model, the maximum speed of eastward flow on the Cheju Strait is twice higher than that of westward flow. According to the result of permanent current, the flow of permanent current showing semi-circle pattern in the southern part of Kojedo was due to variation of topography. According to the result of circulation model in the Cheju Strait, eastward flow entering in the southern waters from the Yellow Sea of Korea were dominant, but outflows westward were weak. These results suggest that it was difficult to move for suspended particulate matter into the Yellow sea from the southern waters through Cheju Strait.

The surface current in the region from Mara-do to mid of the Pacific has been measured by tracking the position of a buoy. The buoy was accidentally released from its original location, near Mara-do, and it has been drifting following the surface current. The tracking started on 27 December 2001 and continued until 29 June 2002. We combined the trace oi the buoy with the wind data available.

It was peformed to estimate the sensitivity analyses and mass balance for tributyltin in Masan Bay, using the model builded by stella program. The results of the sensitivity analysis for dissolved tributyltin and tributyltin in the particulate organic carbon showed that not only organic carbon partition coefficient but also settling rate is important. In the case of tributyltin in phytoplankton, bioconcentration factor of phytoplankton is most important. The results of the mass balance showed that standing stocks of tributyltin in water, in phytoplankton and in particulate organic carbon are 3.29×10⁴g, 1.16×10²g and 3.17×10³g, respectively. In the case of flux, partition to particulate organic carbon showed most high value, 1.64×10³g/4ay, and next were deposition to sediment, 1.64×10³g/day and transportation to open sea by tide, 1.64×10³g/day.

The present study deals with turbulent flow over a long train of fixed two-dimensional dunes, identical in size and shape. A detailed study was carried out by PIV over a range of flow depths in a fully developed region. The present study confirmed the global features of flow past a fired dune noticed in previous studies, i.e. the size and shape of the reverse flow, the mean velocity and turbulence profiles across the separated and attached flows. The turbulence and shear stress profiles reveal the presence of larger values along the line extending from crest to crest. At stations ahead of the dune crest, the presence of a peak in the streamwise turbulence profiles around y/h = 2 indicates the sustenance of turbulence generated in the separation zone of the previous zone which will be carried over to the next dune.

This paper presents the results of a ten-day long survey for assessing the possibility of further oil spillage from the sunken tanker, Kyung-Shin(995 G/T), which had sunken in the East Sea, off Pohang City, in February 1988. The survey was conducted using remotely operated vehicle(ROV), manned submersible and ultrasonic thickness gauge in September 2001. The external inspection by the optical camera shows that small scale oil spill has been continued from the sunken ship. It's hull thickness was also measured at several points of the ship, using an ultrasonic sensor for assessing the current corrosion status of the sunken ship. Taking into account the results of this survey and the existing salvage report, it is estimated that the remaining oil in the tanker is approximately 600 ㎘, and this oil could be leaked into marine environment due to continuous severe corrosion if no preventive is taken.
