JOURNAL FREE ACCESSThe surveying vessel “TAKUYO” of the Hydrografic Office of Japan had collected bluish grey ooze from the bottom of the Japan Trench. Various amino acids as listed in Table 2 have been found from this sample. The writer has attempted to investigate marine environments from the view point of amino acid analysis.View full abstractDownload PDF (3594K) -

JOURNAL FREE ACCESSH. Stommel's idea about the abyssal circulation in all the world has theoretically departed from the existence of the sources (areas of sinking motion) in the northern part of North Atlantic and in Weddell Sea, and the steady ascending motion in deep layer in sea areas of middle latitudes. The present author has researched into the abyssal circulation from the viewpoint of data analysis.
The authors study resulted in the following : The sinking motion of the northern part of North Atlantic is superior to it of Antarctic Ocean on an average. According to the distribution of oxygen, it may be seen that there is an area of sinking motion in Ross Sea. From the horizontal distribution of phosphate-p at deep layer, we can find that abyssal circulation is similar to chart of Stommel.View full abstractDownload PDF (1098K) -

JOURNAL FREE ACCESSA new type of bathythermograph for deep-sea research is presented. This instrument records the sea water temperature and the observed depth on a smoked glass plate. Experiments in the field show that the vertical profiles of temperatures against pressure to 1000m depth can be recorded successfully.View full abstractDownload PDF (2841K) -

JOURNAL FREE ACCESSTsuiyama harbour in Hyogo Prefecture is situated at the mouth of the River Maruyama flowing into the Japan Sea. This harbour has been suffered from the drifting sand, as is the case of the estuaries of rivers open on the Japan Sea, but not so remarkably as in the others.
By bathymetrie charts obtained several times hitherto, and by sampling the bottom deposits in the vicinity of this harbour, the author investigates movements of the drifting sands in this region and the effect of the embankments upon these movements. The results will be introduced in this report.View full abstractDownload PDF (1328K) -
II. The Graphical Method of finding the Correction “κ” in Chlorinity Determinations of Knudsen's MethodNaobumi KOSHIMIZU1962 Volume 18 Issue 1 Pages 23-25

JOURNAL FREE ACCESSThe values of the correction “κ” in chlorinity determinations in Knudsen's Hydrographical Tables are generally mixed number. Then, the calculation of the interpolation of the actual titration value for finding the correction “κ” is troublesome, and, according to the author's calculation, the error of the correction “κ” is 0.01 (‰) owing to the titration error and the drop error. The author has taken those errors of chemical analysis into account in the calculation of the value of κ, and calculated the values of the correction “κ” by introducing directly the titration values of a which are integer. Using those values of the correction “κ”, the author has deviced a graphical method finding the values of κ when both α and a are given.View full abstractDownload PDF (505K) -
III. The Range of the Instrumental Errors of Knudsen's Burette and Pipette and the Simplified Method of the Calculation of the Correction for Both ErrorsNaobumi KOSHIMIZU1962 Volume 18 Issue 1 Pages 26-28

JOURNAL FREE ACCESSBy the results of calibrations of Knudsen's burettes and pipettes of about thirty examples respectively, the author has ascertained the ranges of the errors of them. The absolute values of the ranges are mostly within 0.20 in the case of burettes by the unit of per mill, and almost the same value in the case of pipettes by the unit of cubic centimeter. Therefore, when we employ the burette and the pipette which are of the same sip in both instrumental errors, the correction ε for the total errors may he given in the simplified formula as follows:
ε=εB-R/15·εP,
where εB and εP are instrumental errors of burrete and pipette respectively, and R is the burette reading.
It is convenient for chlorinity determinations that the value of the correction of the instrumentel error is approximately zero or small. The author has deviced the method of combination of the instrumental error of the burette and that of the pipette in order that the value of the correction is approximately zero or small in the above formula.View full abstractDownload PDF (535K) -

JOURNAL FREE ACCESSTwenty-one species of copepods are identified from the vicinity of Mukaishima in Bingo-Nada. Among them, Eucalanus mucronatus, E. subcrassus, E. crassus, Acrocalanus gracilis, Pseudodiaptomus marinus and Microsetella norvegica are newly found in this area. The first three species occurred only in autumn. Acrocalanus gracilis occurred from autumn to early winter. The other two species were found throughout the year. Dominant species in copepod communities were Paracalanus parvus, Acartia clausi, Oithona similis, O. nana, Oncaea venusta, Corycaeus affinis and Microsetella norvegica. They thrived throughout the year except for Acartia clausi which does not exist from August to November. Of the other species, Calanus helgolandicus, Centropages abdominalis, Euterpina acutifrons mainly appeared in the colder season, and Centropages yamadai, Calanopia thompsoni, Labidocera bipinnata, Pontellopsis tenuicauda, Acartia erythraea and Tortanus forcipatus mainly in the warmer season.View full abstractDownload PDF (742K)
