Animation author in Showa Seo Mitsuo
No full textFurthermore, it is also surprising that not much studying has been done on Seo Mitsuo either, who created about 25 pieces of work during the period of 1932 and 1949 through a method known as “Sell Animation.” The purpose of this study is to understand Kenjo Masaoka, a genius of Sell Animation, and analyze his works in order to identify the nature of those works.There are five main points in conclusion: first, of division of labor was developed more by use of a cell, and that a big hint was given to a division system of an after Japan animation co. The thing in which two could express a movement of the character which makes a story stand out freely using a cell. Such as applying to a movie cartoon three of taking a picture, various methods are tried, consequently, the thing which improved the quality of a movie cartoon. I kept studying four music methods, and that musical visualization was advanced. Five kept educating the posterity represented by Mitsuyo Seo and others, and that their ability was improved

Report on Japan-Australia collaborative research on marine biology in the Prydz Bay area, Antarctica in 1992
No full textA three-year research collaboration with biologists in the Australian Antarctic Division, on the variability in the Antarctic marine environment and its effects on the biological processes has started from the 1991/92 austral summer season. For the first year, a joint proposal of H. MARCHANT (Australian Antarctic Division) and M. FUKUCHI (National Institute of Polar Research) to investigate biological processes in the Prydz Bay and the coastal ice-covered areas, titled "The production and fate of biogenic particles in the Antarctic marine ecosystem" was submitted and carried out during the voyage 6 of the Australian Antarctic research ship, AURORA AUSTRALIS from January 9 to March 27,1992. Main objectives of this research were; 1) to investigate seasonal variations in the primary and secondary productions and sinking processes of the products throughout the year with moored instruments and 2) to estimate the contribution of different components to the production and sinking processes of lower trophic organisms. For these objectives, time-series sediment traps with an in-situ chlorophyll recorder and current meters were deployed and water collections, plankton-net samplings and incubation experiments were carried out in the Prydz Bay area. The feeding selectivity of the antarctic krill (Euphausia superba), a dominant primary consumer in the Southern Ocean, was preliminarily investigated with a simple electrophysiological method
Bromoform concentrations in slush-layer water in Antarctic fast ice
No full textBromoform concentrations in water of the slush layer that developed at the interface between snow and sea ice were measured during the seasonal warming in Lützow-Holm Bay, East Antarctica. Mean bromoform concentration was 5.5 ± 2.4 pmol l-1, which was lower than that of the under-ice water (10.9 ± 3.5 pmol l-1). Temporal decrease in bromoform concentrations and salinity with increasing temperature of the slush water suggest that the bromoform concentrations were reduced through dilution with meltwater input from the upper surface of sea ice. In contrast, bromoform concentrations in the under-ice water increased during this period while the salinity of the under-ice water decreased. It is speculated that the sea ice meltwater input contained high bromoform concentrations from the brine channels within the sea ice and from the bottom of the ice that were contributed to the increased bromoform concentrations in the under-ice water
Chlorophyll-α content in the surface water along the course of the FUJI to from Antarctica in 1976-1977
No full textDuring the relief cruise of the FUJI to Syowa Station, Antarctica, from November 1976 to April 1977, the chlorophyll-α contents in the surface water were measured at 150 stations as a part of the routine observations of marine biological program of the 18th Japanese Antarctic Research Expedition. The chlorophyll-α distributions were generally similar to those noticed in the previous observations. The maximum value was observed in the pack ice area of Prince Olav Coast, Antarctica (2.40 mg chl-α/m^3). The high values were also seen in the Celebes Sea, Makassar and Malacca Straits
Incorporation of nitrogen compounds into sea ice from atmospheric deposition
No full textTemporal measurements of temperature, salinity, water–oxygen isotopic ratio and nutrient concentrations at Saroma-ko Lagoon, southern Sea of Okhotsk, were made in February–March 2008 to examine the processes by which nitrogen compounds from the atmosphere were incorporated via snowfall into sea ice. Granular ice made up more than half the ice thickness, and the mass fraction of snow in the snow-ice layer on top of the ice ranged from 0.8% to 46.9%. The high concentrations of NO3− + NO2− and NH4+ observed in the snow and snow-ice throughout the study period were likely due to the proximity of the study site, in northern Japan, to the east coast of the Asian continent. Pollutants containing high NO3−and NH4+ concentrations are transported from East Asia and deposited in snowfall over the sea ice in the southern part of the Sea of Okhotsk. Compared with NO3− + NO2− and NH4+ concentrations, PO43− concentrations in the snow and snow-ice were low. The strong correlation between the NO3− + NO2− and NH4+ concentrations in the snow-ice and the mass fraction of snow indicates that the nitrogen compounds on top of the sea ice were controlled mainly by the snow contribution to the sea ice when snow-ice predominated. Our results indicate that chemical cycles in sea ice can be affected by polluted precipitation (snow) originating from a nonpolar sea
DMSP and DMS in coastal fast ice and under-ice water of Lützow-Holm Bay, eastern Antarctica
No full textThe combined concentration of total dimethylsulfoniopropionate and dimethylsulfide (DMSP+DMS) were measured in Antarctic fast ice on the coast of Lützow-Holm Bay, eastern Antarctica. High bulk-ice DMSP+DMS and chlorophyll a concentrations were found at the bottom of the sea ice, and these concentrations were higher than those in the under-ice water. The bulk-ice DMSP+DMS and chlorophyll a concentrations were highly correlated (r2=0.68, P<0.001), suggesting that the high bulk-ice DMSP+DMS concentrations were caused mainly by the presence of algae assemblages in the ice. The calculated brine DMSP+DMS concentrations were as high as 1100 nM in the bottom ice layer, and the vertical profile patterns of brine DMSP+DMS concentrations were almost the same as for the bulk ice, mainly because of the small amount of variability in the vertical brine volume fraction. DMSP+DMS and chlorophyll a concentrations in the under-ice water increased, whereas the salinity of the under-ice water decreased, during the sampling period. These results reflect the supply of freshwater containing high levels of DMSP+DMS to the water just under the ice as the ice melted. These results suggest that sea-ice melting could be important to sulfur cycling in coastal ice-covered regions of the polar oceans
