    Dimensions and sinking speeds of tropical radiolarian skeletons from the parflux sediment traps : technical report (2017)
    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-25
    Description: Length, width and projected area (58 species) and weight (53 species) of radiolarian. skeletons, mainly from the Panama Basin PARFLUX sediment trap (5°21.8'N, 82°01.4'W) samples, were measured. Volume and density contrast were computed. The measured mean weight values for the examined species range from 0.05 pg/shell to 24 μg/shell. The weight is best correlated with projected area among the studied size dimensions of Radiolaria as a whole group. The density contrast of the radiolarian skeletons, relative to seawater, generally falls between 0.01 and 0.5 g/cm3 and appear to be constant with an order of magnitude increase of the shell diameter. The sinking speeds of specimens of 55 radiolarian species measured in 3, 10 and 20°C seawater range from 13 to 416 m/day. Despite the wide variety of morphology between the species, the sinking speed is best correlated with weight/shell with reasonably small deviations from a regression line. Using the sinking speeds residence times of the 55 species in the 5 Krn pelagic water column range from 2 weeks to 14 months.

    Pelagic diatom fluxes I : size fractioned time-series results from subarctic Pacific Station Papa during 1982-1983 (2016)
    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-26
    Description: A time series vertical flux assessment of pelagic diatoms was conducted during September, 1982 through September, 1983 at subarctic Pacific Station PAPA (50°N, 145°W; water depth 4200 m) using PARFLUX sediment traps deployed at 1000 and 38000 m. The time series sediment trap samples were collected for 11 to 16-day periods during the year; a total of 24 samples represent a full year's record of flux. Eighteen taxonomic groups of diatoms were enumerated, based on a census of four wet-sieved size fractions: 250-1000μm, 125-250μm, 63-125μm, and 〈 63μm. In order to study the sinking processes of diatoms, detailed information on frustule integrity was acquired. For example , counts of single valves were separated from frustules. Size-fractioned fluxes of all the counting groups are graphically presented, which provides a data base for further investigations.

    Two year time-series fluxes of Silicoflagellates and Actiniscus : size fractioned results from subarctic Pacific Station Papa, 1982-1984 (2016)

    Details
    Publication Date: 2022-05-26
    Description: A seasonal flux study of silicoflagellates and Actiniscus was conducted at subarctic Pacific Station PAPA (50°N, 145°W; water depth 4200 m) during September, 1982 through August, 1984 using PARFLUX time series sediment traps deployed at 1000 m and 3800 m depths. The time series sediment trap samples were collected for 4 to 16-day periods depending on the samples; most of the samples were collected for 14 to 16-day periods. A total of 47 continuous samples represents nearly a two-year record of the fluxes of silicoflagellate and Actiniscus taxa at 3800 m depth. An additional 12 samples from 1000 m represent a continuous 6-month period which provides a pair of samples from two depths of each time series. Analysis of the paired samples is essential to understand particle sinking processes. Seven silicoflagellate taxa, several additional variants of silicoflagellat.es, and Actiniscus pentasterias group were enumerated, based on a census of four wet sieved size fractions: 250-1000μm, 125-250μm, 63-125μm, and 〈63μm. A total of more than 32x103 specimens were identified to species level and counted in this study. Statistics of the counts are given. The fluxes of silicoflagellate taxa of all four size fractions are graphically presented. This report provides a detailed data base for further investigations of seasonal silicoflagellate fluxes in the area.

    Notes: [Auszug] Conventional methods of measuring underground elec-tromagnetic radiation (EMR) associated with seismicity are not effective in a highly industrialized area with high levels of urban noise. Measuring EMR using a steel pipe in a deep borehole as an electrode was therefore proposed, especially to ...

    Human hepatocyte growth factor in blood of patients with fulminant hepatic failure (1991)

    Notes: Abstract The levels of human hepatocyte growth factor (hHGF) in sera obtained from patients with various liver diseases were determined using adult rat hepatocytes maintained in primary culture. The mean hHGF activity for 22 patients with fulminant hepatic failure was about nine times greater than that found in normal human serum. The increase in serum hHGF activity seen in two patients with “acute-on-chronic” hepatitis was similar to that found in patients with fulminant hepatic failure. The serum level of hHGF from patients with acute hepatitis is related to the stage of their illness. The average value for 31 patients was about three times that of normal human serum. In some patients, the time course for the increase in serum hHGF activity was similar to that demonstrated for alpha-fetoprotein. The mean hHGF activity in serum for the 33 patients with chronic hepatitis and from 25 patients with liver cirrhosis was increased also compared with that of normal human serum. In addition, serum hHGF activity in three of seven patients studied after partial hepatectomy for a space-occupying lesion of the liver was increased. These data suggest that the increase in serum hHGF activity present in patients with various liver diseases reflects a self-defense mechanism that is involved in the process of liver cell regeneration.

    (Table 1) Stratigraphic distribution and abundances of Cretaceous radiolarians from ODP Holes 130-803D and 130-807C (1993)
    PANGAEA
    In:  Supplement to: Takahashi, Kozo; Ling, Hsin Yi (1993): Cretaceous radiolarians from the Ontong Java Plateau, western Pacific, Holes 803D and 807C.

    Description: Among the five sites drilled during Ocean Drilling Program Leg 130, two deep holes (8O3D and 807C) penetrated Cretaceous sediments overlying the basaltic pillows, flows, and possibly basement rocks. Abundant, poorly preserved radiolarians with limited diversity were recovered from a few horizons within the sediments proximal to the basalt. At Site 803, three thin layers of radiolarites interbedded with claystone and clayey siltstone yielded radiolarian assemblages of late Albian age. At Site 807, several layers of radiolarian siltstones were recovered proximal to the basalt. Among them the most significant radiolarian assemblage is an Aptian fauna, located approximately 7 m above the basaltic flows. The Aptian radiolarian age for Site 807 is at least in accord with those suggested by planktonic foraminifer and paleomagnetic evidence. These Cretaceous radiolarians are the oldest assemblages recorded from the Ontong Java Plateau region.
