“…This was the world's largest macroalgal bloom ever reported and covered about 400 km 2 of coastal area, with over one million tons being removed by >10,000 people ). Also, green macroalgal blooms have periodically been reported along the coast of Korea Kim et al 1998). However, an extraordinary phenomenon has been reported recently, wherein banded floating green slicks were crossing the open ocean.…”

Samples of the massive drifting green alga, Ulva linza, were collected from the coastal waters of the Yellow Sea, southwest of Korea, in early July 2009, and cultured under laboratory conditions. The effects of various temperature (10-30°C) and irradiance levels (0-1,000 μmol photons m −2 s −1 ) on photosynthesis, growth, and tissue nutrient content of U. linza were investigated in laboratory for both individuals of the latestage vegetation (LSV) and the early-stage vegetation (ESV). After 1 h acclimation to various irradiance and temperature conditions, maximum gross photosynthetic rate of ESV was significantly higher than those of LSV. In the long-term (7-d) acclimation experiments to various irradiance and temperature levels, gross photosynthetic rates of ESV individuals were also significantly higher than those of LSV individuals. High photosynthetic rate of ESV individuals induced increase in mass of about 60% over the growth saturation irradiance (136 μmol photons m −2 s −1 ) and about 20% under low temperature conditions (10-15°C) during 7-d. The gross photosynthesis of LSV individuals was low when examined under temperature and irradiance conditions that were optimum for ESV growth. Consequently, freefloating U. linza exhibits cellular senescence beginning in early July in the Yellow Sea, and green tides formed by this species cannot be maintained beyond this time in the open sea. However, we expect that U. linza can proliferate quickly after settlement on new coastal habitats of the Yellow Sea because of the high tissue nitrogen utilization for photosynthesis in ESV, which is formed by germination of reproductive cells.

“…Communities at Jusamdo in the Yellow Sea are characterized by Desmarestia ligulata at subtidal depths of 5 m and vertically broad distributions of S. thunbergii (Heo et al 2011); Daejin communities in the East Sea are marked by Symphyocladia latiuscula and Phyllospadix japonicus (Shin et al 2011). These differences were probably due to several factors particular to each local region, such as annual mean sea surface temperature, difference in tidal level, latitude, hydrodynamics, topography, or turbidity (Chung et al 1998, Kim et al 1998, Stewart and Carpenter 2003, Kang et al 2011. Two species, S. latiuscula and D. ligulata, that appear to be dominant species on Daejin in the East Sea and Jusamdo in the Yel- In summary, our intensive study of macroalgal assemblages on the Marado coast provided great insights into the distribution pattern of macroalgal assemblages in unpolluted marine areas of Jeju Island.…”

Marado is a small rocky island located off the south coast of Jeju Island and acts as the first gateway of the Kuroshio Current to Korean coastal ecosystems. This island is one of the most unpolluted and well preserved sea areas around the Jeju coast. We extensively observed macroalgal assemblages of species and functional forms in the intertidal and subtidal zones through four seasons on Marado, Jeju Island, Korea to demonstrate the seasonality of vertical distribution patterns and biomass. A total of 144 species (14 Chlorophyta, 40 Phaeophyta, and 90 Rhodophyta) were identified in quadrats and were analyzed seasonally and vertically to define the variation patterns. The annual mean biomass of macroalgae was 2,932.3 g wet wt m -2 and the highest value was recorded in spring and the lowest was in winter. The annual dominant species by biomass was Ecklonia cava followed by Sargassum fusiforme, S. macrocarpum, Amphiroa galapagensis, Chondria crassicaulis, and S. thunbergii. Obvious biomass zonation patterns of macroalgal species were detected in relation to tidal height and depth. Macroalgal biomass, diversity index (H'), and community dynamics were the highest in the shallow subtidal zone. Species number was higher in the subtidal than in the intertidal zone and similar throughout the entire subtidal zone. Our results provide revealing insights into the distribution patterns of macroalgal assemblages in an unpolluted sea area around Jeju Island.Key Words: biomass; distribution; Jeju Island; macroalgae; Marado; seasonal variation INTRODUCTIONMacroalgal ecologists strive to understand the environmental factors and phenomena that affect macroalgal zonation patterns (Choi and Kim 2004, Balata and Piazzi 2008, Konar et al. 2009, Kang et al. 2011. Macroalgal zonation patterns commonly undergo changes in abundance, diversity, and community dynamics through natural processes along tidal height and depth gradients. The highest level of these patterns is generally found at mean low water (MLW) and decreases with both increasing depth and intertidal height (Garrabou et al. 2002, Choi and Kim 2004, Kang and Kim 2004, Balata et al. 2006, Konar et al. 2009. Although numerous studies have described these general zonation patterns, recent studies have suggested that these patterns may not be generalizable across geographic regions because peaks in abundance or diversity are not found consistently in particular depth strata (Balata and Piazzi 2008, Konar et al. 2009, Heo et al. 2011, Kang et al. 2011. Therefore, there is great interest in investigating not only these exceptional patterns but also different zonation patterns in species composition, diversity, abundance, and community dynamics among areas at local scales (Konar et al. 2009, Heo et al. 2011, Kang et al. 2011, Shin et al. 2011.Macroalgal growth is influenced by multi-factorial in- This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/3.0/) which permits unrest...

“…Kim et al (1998) concluded that depth is a primary factor constraining the seasonal fluctuations of the numbers and abundance of species in subtidal benthic algal communities. Studies have shown that deepwater algal assemblages are more stable throughout the year compared to shallow-water assemblages (Kim et al, 1998;Piazzi et al, 1999Piazzi et al, , 2002. In general the number of species as well as the percentage cover and biomass of macrophytes decreases with increasing depth independent of season (Kim et al, 1998;Yoo, 2003a).…”

Seasonal dynamics of subtidal macrophyte assemblages in Sobol Bay (Peter the Great Bay, Sea of Japan) in relation to depth anna v. skriptsova and irina r. levenets A.V. Zhirmunsky Institute of Marine Biology, Far-Eastern Branch of the Russian Academy of Sciences, Vladivostok, 690041, Russia This paper describes the species composition, vertical distribution, and the seasonal changes in the biomass of subtidal macrophytes in Sobol Bay (Peter the Great Bay, Sea of Japan). The samples were collected in the depth-range from 0.5 to 4 m. A total of 65 macrophyte species were identified, among which were 10 species of Chlorophyta, 17 of Phaeophyceae, 37 of Rhodophyta and 1 of Magnoliophyta. Multivariate analyses were performed to detect spatial and temporal variations. Maximum species richness was registered in June, with a particularly dramatic biomass increase of brown algae. Both the number of species and the biomass of macrophytes decreased with increasing depth. Depth clearly affected the patterns of seasonal fluctuations of the species composition and biomass. In the study area, the species composition of the shallow-water algal assemblages was more stable throughout the year compared to that of the algal assemblages found in deeper waters. In total, four macrophyte assemblages were identified in the bay. A Phyllospadix iwatensis and Coccophora langsdorfii dominated assemblage occupied muddy-gravel bottoms in depths from 0.5 to 2 m throughout the year. An assemblage, co-dominated by annual brown algae Desmarestia viridis and Costaria costata, occurred at depths more than 3 m at late spring. Two other assemblages occurred on the rock and boulder bottom at 0.5 -2 m depths, but they were temporally separated. An assemblage co-dominated by annual laminarian algae (Undaria pinnatifida and Costaria costata) developed at late spring and was succeeded in the autumn and winter by a Tichocarpus crinitus, Ulva lactuca, Sargassum pallidum and Codium fragile co-dominated assemblage. A comparison between the data obtained in the present study and the results of a previous study conducted in 1927 shows that the macrophytes assemblages in Sobol Bay underwent little change.
