서해 남부와 남해 서부의 한 정점에서 수온 및 염분과 멸치 어군의 특징의 관련성 시각화

Abstract

Morphological and positional characteristics of anchovy aggregations, confirmed by trawling, were examined in two locationsof the southern part of theWest Sea (T1) and the western side of South Sea (T11) of South Korea. Morphological characteristics(mean length, height and area) of the anchovy aggregations at T1 were smaller than those at T11, however the positional characteristics(distributional depth and bottom depth) of the aggregations at T1 were larger than those at T11. Diverse dataset suchas the ship’s cruise track, the cruse map, and interpolated three-dimensional-like water temperature were visualized in multipledimensions. For a comprehensive understanding of the anchovy aggregations within their surrounding circumstances, the interpolatedwater temperature transferred to the location of anchovy aggregations at both stations were visualized based on geospatialinformation. Using quantitative investigation, the overall range of change in water temperature and salinity of anchovy aggregationsat stations was considerably small. However, the water temperature and salinity of anchovy aggregations at T11 weresomewhat higher than those at T1.
