Abstract
We investigated the temporal changes in the structure of mesozooplankton community around Ulleung-island, Korea during spring and summer of 2017. Study stations at Ulleung-island consist of 6 coastal stations around Ulleung-island and 6 stations on transect from Ulleung-island to open-sea. Mesozooplankton samples were collected in the surface mixed layer (SML) by vertical hauls using a standard type net. The average SML depths were ~28 m in spring and ~24 m in summer. The vertical distribution of temperature ranged 11.3-17.8°C (average = 16.5°C) during spring and temperature ranged 16.1-26.1°C (average = 22.8°C) during summer. Relatively cold water (~12.3°C) was observed at 25 m depth at st.30 during spring. The abundance of mesozooplankton ranged between 917-10,648 inds.m-3, peaked at st.30 during spring and ranged between 960-7,175 inds.m-3, peaked at st.50 during summer. The average abundance for mesozooplankton was 1.6 times higher in spring than summer. The mesozooplankton community was numerically dominated by copepods which comprised 82.7%(spring) and 45.7%(summer). The next dominant groups were appendicularians (13.1%) and cirripedians (1.9%) during spring, and Noctiluca scintillans (26.4%), thaliaceans (10.1%), cladocerans(6.5%) and foraminiferans (6.5%) during summer.tions on transect from Ulleung-island to open-sea.
