On-Going Research
Food availability (environmental forcing)
- Phytoplankton community structures identified by chemotaxonomic (HPLC) analyses and the size fractionation (flow-cytometric) analysis
Physiological energetics (Organism)
- Evaluating physiological processes for adapting to varying environmental conditions
Growth and reproduction (Population)
- Studying the energetics of gametogenic development
Community structure and trophic interactions (Community and Food web dynamics)
- Dealing with more comprehensive ecosystem dynamics
- Highlighting the influence of climate-induced changes in hydrographic structure and circulation (e.g., stratification, thermal regimes and current patterns) on the structure and function of ocean food webs and the productivity of living ocean resources
Current projects
- Long-term marine ecosystem monitoring (LTMER, KIMST 2011-present)
- East Asian Seas Time series-I program (EAST-I, KIMST 2006-present)
- Assessment of marine environmental status and carrying capacity in coastal and aquaculture ecosystems (NFRDI 2010-present)
- Ecosystem-based management of fisheries resources (KMOF 2012-present)
[Long-term Marine Ecosystem Research (LTMER)]
Goal

[Assessment of marine environmental status and carrying capacity in coastal and aquaculture ecosystems ]
Goal
The ascidian Styela clava has recently become a common species for suspended aquaculture in Korea. Because of the ecological and commercial importance of this species, it is important to understand its physiological energetics. The purpose of this study was to determine fundamental biological traits for the cultivation of S. clava. Physiological processes (food consumption, feces production, ammonia excretion and respiration) of the ascidian were measured under in situ environmental conditions.
