■ Pollution Purifying Ability of Coarse Sediments in Garorim Bay and Assesment of its Enviromental Changes
• Results
About 30% of Garorim Bay is covered with coarse sediments. The ability of organic matter decomposition is well known to ss greater in coarse sediments than in fine ones. Methods like pore water extraction and benthic chamber deployment are commonly used for fine sediments. However, these methods are difficult to apply to coarse ones because of fast advection of porewater and high permeability of coarse sediments.

We have developed a series of optical techniques utilizing optode sensors, a digital camera, and graphic analyzing software. Oxygen contents in porewater were recorded on optode films in contact with coarse sediment in situ. Digital images of oxygen distribution on the films were quantified by a dedicated software to produce profiles of oxygen concentration in porewater.

Results from the coarse sediments in Garorim Bay showed oxygen consumption rate to be 26.6 mmol m^-2 day^-1, seawater filtering rate to be 148.5 L m^-2 day^-1, and organic carbon oxidation rate to be 219 mgC m^-2 day^-1. Applying these numbers to total area of 33.8 km² of Garorim Bay, we have estimated seawater filtering rate of 1.8 × 10⁹ ton yr^-1 and of organic carbon oxidation rate of 7.4 tonC yr^-1 for the bay.

■ A study on fluctuation factor of phytoplankton and primary production in the Garolim Bay of Yellow sea, Korea
• Results
The concentrations of chlorophyll and cells count of phytoplankton in the Garolim bay weren't have a big difference with previous result and different Yellow coastal areas. The concentrations of chlorophyll increased in summer, decreased in winter and fall in 1st year. Spatially, inner part of the bay was higher than in the outer but it appear to similar concentration at all sites.

The concentrations of chlorophyll slightly increased in spring but appeared on spatially small difference and seasonally in 2nd year.
Number of phytoplankton species were 89 species in 1st year that emerged more 20-30 species than before. However, this results observed emerged species of phytoplankton in detail on natural scientific approach unlike previous investigation. So there is no increased number of emerged species. Number of phytoplankton species were 74 species in 2nd year. Dominant species of phytoplankton was Crypto, Paralia sulcata, Skeletonema marinoi ect. in 1st year, dominant species was Crypto, Paralia sulcata, Asteroplanus karianus ect. in 2nd year. These were predominant speices in Yellow sea, emerged dominant species in the Garolim Bay in the past. The daily primary productivity was higher than existing result in 1st year in the Garolim Bay, similar to Cheonsu Bay, but was lower a quarter than average primary production in Korea.

■ Temporal and spatial variation of nutrients and trace metals, and tracking material sources in Garorim Bay
• Results
The present status of water and sediment quality in Garorim Bay was investigated. In addition, material sources were identified using source tracer. Seawaters were collected at 10 sites during four periods covering four seasons(Jun & Oct 2015, Jan & Apr 2016) and sediments were collected during two periods (Jun 2015 & Aug 2016). general water quality including turbidity, DO, Temperature and salinity, nutrients, and trace metals were analysed for seawaters, and trace metals and Pb isotopes were analysed for sediments.
- Vertically homogeneous distribution of water quality parameters was observed due to strong tidal mixing. Seasonally nutrients in inner bay were exahusted during the periods of Jan to May, and hence they were supplied from offshore, on the meanwhile, from Jun to Oct, nutrient concentrations were lowered in offshore due to active biological activities but active biological remineralization occurred in inner bay from wide tidal flat. Mn, Co and Pb were supplied from sources in inner bay while Zn was supplied from outer bay and removed in inner bay. Water quality during four seasons was assessed using Korea Water Quality Standard and showed good quality (1-2 grade) and the levels of heavy metals were very low.
- Cs concentration in sediments represents well the grain size distribution, and fine-grained sediments in tidal flat and coarse grained sediments in channel area.
- Heavy metals in sediments showed lower concentrations than Korean sediment quality guideline and very good linear relationships with Cs concentrations, which indicates little contaminants input in Garorim Bay.
- Pb in sediments of Garorim Bay was estimated as mixtures of materials from Gyunggi Bay sediments and Seosung ore using Pb isotopes, and might be suggested that it was suppled through groundwater from ore deposits.

• Expected Contribution

■ Marine ecosystem research in Garorim Bay : Emphasis on zooplankton and fish larvae
• Results
- Environmental factors
① Temperature : Mean temperature was 9.1 ℃ to 27.5 ℃. It is characteristic of a typical temperate sea that low temperature in winter and high temperature in summer.

② Salinity : Mean salinity was 31.5 psu to 31.8 psu. Overall, the salinity of inner bay stations was higher.

③ Chlorophyll a : Mean concentration of chlorophyll a was 0.67 ㎍/l to 2.87 ㎍/l(peaked in June).

④ Transparency : Mean transparency was 0.9m to 1.2m, Overall, the transparency of inner bay stations was shown low. These changes are thought to be caused by the increase in the amount of re-suspended material in lower layer as the depth of water becomes shallower toward the inside of the bay.

⑤ Nutrients : N / P ratio was 26.68 : 1. So that, Phosphate ( P ) is limiting factor to phytoplankton growth in Garorim Bay.

- Zooplankton
32 taxa belonging to 7 phylum were appeared in Garorim Bay. Acartia ohtuskai (22.8%) was formed the largest taxa in this study. And then, Acartia hongi (22.6%), Paracalanus arvus s. l. (20.4%), Decapoda larvae (11.8%), Mollusca larvae (5.4%) was appeared.

- Fish larvae
In order to overcome the limitations of existing morphologic identification methods, we have analyzed the fish larvae by 'DNA barcoding', one of the molecular biological method. As a result, 13 taxa of fish larvae was appeared in this study. Total abundance of fish larvae was increased April to August, but it was not collected in October. This distribution of fish larvae is similar to previous study(Hur et al., 1984).

■ Studies on the production and cultivation of single-oyster using discarded embanked farms
• Results
The results of the first year on the marine environment showed that sea water ranged from 3.43℃ to 23.77℃ for temperature, from 19.35 psu to 23.64 psu for salinity, from 0.23 ㎍/L to 5.21 ㎍/L for chl-a in the discarded embanked farms during September 2014 to January 2015. For parent shellfish management technique development, survival rate experiments were carried out on five test sites from high temperature to low temperature. The survival population was 22.5% ∼ 47.7%.
The results of the second year on the marine environment showed that sea water ranged from 5.2℃ to 33.4℃ for temperature, from 19.0 psu to 28.7 psu for salinity, from 6.3 mg/L to 13.3 mg/L for dissolved oxygen (DO), from 5.96 to 9.7 for pH, from 0.64 ㎍/L to 4.70 ㎍/L for chl-a during January 2015 to September 2015. The results on experiment of oyster larvae growing with hanging culture (October 2014 ∼ July 2015) in discarded embanked farms showed the larvae grew up to 23.91 mm of width and 37.41 mm of height after 30 days of experiments. On the last time to measure, it grew up to 30.16 mm of width and 47.10 mm of height, so that the size of larvae grew up as 7 mm of average width and 10 mm of average height during the experiment.
As a result of the verification test of the patented shellfish aquaculture device, the size of larvae grew up as 40 mm of width and 30 mm of height, which indicate the patented aquaculture device affect growth rate of the larvae more than hanging culture. The survival rate of the larvae population was as high as 80%∼95%. This survival rate is higher than first experiment on survival rate of natural parent shellfish. This result can be thought that perish of natural parent shellfish occurred early because they exhaust their physical stamina to spawn before the experiment.
The results of the third year on the marine environment showed that sea water ranged from 5.2℃ to 34.5℃ for temperature, from 24.3 psu to 26.8 psu for salinity, from 7.1 mg/L to 10.8 mg/L for dissolved oxygen (DO), from 7.4 to 8.4 for pH. In order to develop seedling collection technique of larvae in discarded embanked farms, artificial spawning by using warming and ultraviolet method was conducted. After successful spawning, 10 individuals were weighed and measured size monthly.
Monthly larvae measurements showed an average size of 3.5 mm and weight of 3.0 mg in June 2016, size of 6.6 mm and 27.0 mg in July 2016, size of 10.8 mm and weight of 114.2 mg in August 2016, size of 14.17 mm and weight of 195.8 mg in September 2016. Among the larvae collected, 6 larvae (April 2016) and a larva (May 2016) were died at Umbo larvae stage. 7 larvae (April 2016), 32 larvae (May 2016) were dead at pediveliger larvae stage. 14 larvae (May 2016), 23 larvae (June 2016) and 16 larvae (July 2016) were died at Early spat stage, which indicate the largest number of collected larvae died in June. At Later spat stage, 9 larvae (June 2016), 51 larvae (July 2016), 334 larvae (August 2016) and 98 larvae (September 2016) died, and it was found that the highest number of larvae died in August.

• Expected Contribution
The results of this study can be utilized as a seedling collection technique for bivalves in embanked farms. It can also be used as a source technology for the development of complex aquaculture technology with other shellfish and it can be an effective utilization method of coastal fish farm using discarded embanked farms. It is possible to retain the stable income sources of oyster farmers through efficient supply of low-priced oysters from discarded embanked farms. Domestic and foreign technology leading and intellectual property rights can be secured to prevent national wealth leakage by preceding the cultivation of the embankment pond.

■ Studies on the preservation of commercial shellfish resources and macrobenthos monitoring in Garolim bay
• Results
A total of 171 shellfishes cultivating fisheries in Garolim bay were surveyed with 145 shellfishes, 8 complex cultivating fisheries and 18 village fisheries, and oysters, manila clam, corb shell, abalone, mussels, and jackknife clam were used as shellfish species. The sediment environmental factor is the ratio of organic carbon to total nitrogen in the inner area is relatively high. The sediment composition is composed of sand, silt jinja, and silty silt, but most of the silt is dominant in the inner most part, and sandy area is strong in the middle part of tidal flat. A total of 120 species of intertidal macrobenthos with a density of 630 inds./m² were studied. The mean biomass was 22.59 gWWt/m². The polychaetes were dominant taxon with 52 species (45%) and the mean density of 454 inds./m² (72%) in species and density.
Mollusks were dominant taxon with 11.63 gWWt/m² (51%) in biomass. Appearance pattern of each station was high in the bay entrance area and the right side of the Gopa-island area. The densities were high in the left and right areas of the Seosan, low in the densities in the bay area, and biomass was high in the right area. The dominant species by LeBris index was the polychaetes, Heteromastus filiformis (300 inds./m², 68.58%) at middle of the bay. And followed by polychaetes Mediomastus californiensis (9.43%), crustaceans I lyoplax pingi (4.67%), crustaceans Macrophthalmus japonicus (3.93%) and so on. The diversity highly appeared at inner bay and Seosan tidal flat. The Evenness was mostly high and the richness was relatively low in inner bay. From the community statistics, the macrobenthic community was distinguished into two groups of middle of the bay and inner bay (nearby Seosan). Mean BPI condition of Garolim bay was moderately polluted. In contrast, tmid of the bay, entrance bay area located in Seosan and inner bay located in Taean-gun were highly polluted condition. K-dominance was showed that the disturbances in mid of the bay. The correlation between environmental factors and the density of the sediments was positively correlated with the sand composition and the silt analyzed a negative correlation. Iron (Fe), aluminum (Al) and potassium (K) are found to have a negative correlation with trace metals. R. philippinarum juv. correlated a positive correlation with sand and there was a negative correlation with the silt. Iron, aluminum and potassium in trace metals analyzed a negative correlation but sodium (Na) was found to have a positive correlation. The results of the search for shellfish resources were mostly found in the central area of bay tidal flat. Especially, the densities were high in the high sand composition of Taean area. The lowest area in the bay where the shellfish fisheries are concentrated is low.

It will be provided ecotourism information to tourists through ecotourism map of Chungcheongnam-do tidal flat in fishing ground. Eco-tourists will be have opportunity to understand tidal-flat ecosystems. It will be possible to use it as educational material in government offices and educational institutions in the future.

■ Beach erosion monitoring and numerical modeling around Taean and Anmyeondo in Chungnam
• Results
- 30-days consecutive observation of tidal current and wave.
- Result of harmonic analysis showed the range of 34.9 ~ 42.1 cm/s(M2) on each station.
- Result of coherence analysis showed the available period range of 1.8 ~ 5.7 day
- Result of spectral analysis and empirical orthogonal function showed the three peak in available period
- Development of ocean circulation model using ECOM3D model.
- Numerical model results in terms of tidal height show satisfactory with skill scores over 98%.
- The Tidal height showed the range of 0.57 ~ 4.10 m during flood and ebb phase.
- The current velocity showed the range of 1.5 ~ 3.9 m/s during flood and ebb phase.

• Expected Contribution
- Identify ocean circulation pattern of Taean and Anmyeondo coastal area
- Provide basic data for neighboring disciplines
