However, the native distribution has been extended by human-aided translocations. The turtle lives in freshwater habitats in lowland areas with still or slowly moving water. -
Formation in Chiba Prefecture, Japan
ll Lateral change of foraminiferal fauna at the horizon ● just below the tuffaceous key bed, O7, of the Otadai Formation in Chiba Prefecture, Japan Akio Hatta (Received October 8, 1985) Department of Science Education, Faculty of Education, Kagoshima University. K喝oshima 890, Japan Abstract Lateral change of foraminiferal fauna in a siltstone just below a tu打key bed O7 0f the Otadai Format- ion of Chiba Prefecture was investigated traversing the whole breadth of the Boso Peninsula. ● Faunal composition of planktonic Foraminifera of this horizon shows insignificant lateral change (Text-figure 4). This hirizon may belong to N.22 of the Blow (1969)'s zonation scheme, judging from the ranges of Globorotalia tosaensis Takayanagi & Saito, G. hirtuta d'Orbigny and Globigerina parabulloides Blow. The planktonic ratios of this horizon indicate the values between 70.3 and 84.1 %, and this suggests a typical off-shore environment. Faunal composition of benthonic Foraminifera shows significant lateral change (Text-figure 5). The siltstone beneath the O7 bed contains many specimens of deep sea species, such as Bulimina aculeata d'Orbigny, B. nipponica Asano, Bolivina robusta Brady and Uvigerina akitaensis Asano at every locality. Elphidium group and Quinqueloculina group, which are characteristic of shallow water, are very rare m the central part, but increase westward. ● Faunal change of benthonic Foraminifera is scrutinized by using the factor aualysis. The results are interpreted by referring to the distribution of Foraminifera in the adjacent seas of Japan. From the result, it can be thought that the second factor in the g-mode factor analysis is a parameter of abundance of shallow water elements (Table 2 and Text一五gure 6). -

Sci. Rep., Niigata Univ. (Geology), No. 32 (Supplement), 1–27, 2017 1 Cenozoic biostratigraphy, chronostratigraphy and paleoceanography in the Boso Peninsula and Bandai Volcano in the Aizu region, East Japan Isao MOTOYAMA*, Takuya ITAKI**, Shin’ichi KAMIKURI***, Yojiro TAKETANI**** and Makoto OKADA***** Abstract The Boso Peninsula is a geologically active region where Cenozoic marine sediments formed in a wide variety of depositional and tectonic environments, including ocean basins, trench, trench-slope basins, forearc basins, and shelf to coastal zones. Radiolarians are key to dating most of these sedimentary rocks. In the northern part of the peninsula, Quaternary sedimentary sequences consisting mainly of siltstone and sandstone crop out along canyons of the Yoro and other rivers. There is no better place in the world than the Yoro canyon to correlate the Pleistocene geomagnetic polarity records to marine micro-biostratigraphy, oxygen isotope records, and radiometric ages from volcanic ash layers. This feature is of great benefit to establishing the boundary stratotype of the lower and middle parts of the Pleistocene Stage. In the more mountainous area to the south, visitors can trace the geological history back to middle Miocene through continuous sedimentary sequences. The earliest fossils imprinted in the rock of the peninsula are of early Cretaceous radiolarians from the Mineoka ophiolite complex. Since the Early Miocene the southern part of the peninsula was covered by seas and close to the trench where the Philippine Sea Plate subducts under the North American Plate. Continual subduction of the oceanic plate resulted in a pile of accreted Miocene sedimentary rocks in the southern part of the peninsula. -

Plankton Community Structure in Saguling
17th World Lake Conference, Lake Kasumigaura, Ibaraki, Japan, 2018 P1-1 Plankton Community Structure in Saguling Dam Fattreza Ihsan1, Feni Hastuti1, Regina Leny1, Ika Puspitasari1, Alya Fatina Diandari1, Nisrina Sukriandi1, Beo Nada Rezky1, and Rizkyanti Aulia1 1Institut Teknologi Bandung Keywords: Saguling Dam, plankton biodiversity, Floating Net Cage, fisheries, organic waste ABSTRACT Saguling Dam is a semi natural man-made ecosystem which is located at Bandung District, West Java. For the time being, the characteristic of Saguling Dam is changing because of human activity, such as floating net cage (FNC) activity. FNCs on Saguling Dam increase organic waste level at Saguling Dam. This causes plankton communities to change around the FNCs on Saguling Dam. Plankton communities can be used as an aquatic biologic parameter. Aspects that were inspected are the composition, abundance, and diversity of plankton species. This research’s goal is to compare plankton communities at 3 different state of FNC: dense, distant, and vacant; at three different lake depths: 0, 3, and 6 meter(s) below the surface. Plankton communities on each point of point sample is tested using Sorensen’s index. This research’s conclusion is that the diversity index at Saguling Lake is at medium level; the highest plankton abundance is at 3 meters depth, and the highest predominant genus for phytoplankton is Trachelomonas and for zooplankton is Paradileptus. Sorensen’s index results show that there are similiarities of plankton communities at several point samples. 1. INTRODUCTION Saguling Dam is a semi-natural man-made ecosystem which is located at Bandung District, West Java. The construction of Saguling Dam is done by stemming the flow of Citarum River. -

The Techniques and Tools of Kazusabori Well-Boring
The Techniques and Tools of Kazusabori Well-boring The Techniques and Tools of Kazusabori Well-boring Hiroki Takamura Abstract The Kazusabori method of well-boring originated during the Bunka era years (1804 – 1818) of the Edo period in the area now called Kimitsu-gun, Chiba Prefecture. This method was used to bore a large number of flowing wells, which supplied water for the local community and farming. In the 25th year of the Meiji period (1892), Kazusabori was even utilized to de- velop oil wells in Niigata and Akita and was introduced outside of Japan (in India particularly) as the Kazusa System. It was the most advanced well-boring technique of the time in Japan. Kazusabori well-boring is designated as an important cultural asset in Japan’s List of Important Tangible Folk Cultural Properties (Occupations), and the tools associated with this method are archived at the Chiba Prefectural Kazusa Museum. However, few studies have been done on the development of and tools used for this technique. In February 1981, the author had the opportunity to observe a reen- actment of the Kazusabori method by a master borer working to keep the technique alive. The author utilized the occasion to conduct research on the technical details of the Kazusabori method, the tools used, and the history of its development. As a result, much light was shed on the technical details of Kazusabori well-boring and the actual tools used in the process. Some questions still remain regarding the origin of this method and the use of clayey water. A document in FAO library indicates that Chinese Drilling bears a close re- semblance to Kazusabori well-boring, and could provide clues for further research.
