        1987년 6월-1988년 4월까지 격월로 제주도 해안선주변 10개 정점에서 부유성 갑각류의 현존량과 생산량을 야간채집, 조사하였다. 계절별 평균개체수는 12월에 가장 낮고, 6월에 가장 높았는데, 이들 개체의 대부분(90% 이상)은 90μm 망목의 네트로 채집된 것으로 이뤄졌다. 계절별 평균 현존량의 범위는 6.6-55.0mgm^(-1)(평균 16mgm^(-3))이고, 여름에 높았다. 일일평균 생산량 역시 여름(369μgCm^(-3)d(-1))에 높고 겨울(112μgCm^(-1)d^(-1))에 낮았다. P/B의 비(평균 0.25)는, 수온이 높고 소형 동물플랑크톤의 개체수가 많은 계절에 높은 값을 나타냈다.

        This study investigated the distributional pattern of meiobenthos associated with future deep-sea mining in the Korea Deep Ocean Study area present in the Clarion-Clipperton Fracture Zone (CCFZ) located in the southeastern part of the North Pacific Ocean. Standing stocks of meiobenthos were investigated in benthic impact experiment sites (BIS) and Korea Institute of Ocean Science & Technology long-term monitoring (KOMO) sites during the 2008-2014 annual field survey. A total of 14 taxa of meiobenthos were identified. Nematodes were the most abundant taxon (60-86%). Harpacticoid copepods (5-26%) and benthic foraminifera (1-12%) were also dominant at all sites. The total meiobenthic densities varied from 4 to 150 ind./10 cm2. The mean value of total meiobenthic abundance was higher at BIS than at KOMO sites, but there was no significant difference between the two sites. The mean values of the number of taxa and biomass at BIS and KOMO sites were similar. The mean abundance of nematodes that were the most dominant taxa was also higher at BIS than at KOMO sites. The standing stocks in our study sites were relatively lower than those previously reported at other CCFZ sites. These results seem to reflect a low organic concentration in the study area.
