In the Hydrosphere Science Project (HSP), we provide opportunities for students to practice hydrosphere-related research in a short period of time. Specifically, students will acquire, organize, and analyze various data on the hydrosphere environment across multiple academic fields that make up the Hydrosphere Environmental Group, make presentations during the course, and compile a report. Through this series of experiences, we aim that students will acquire the practical skills necessary for subsequent Master's (Doctor’s) research. Regarding research conducted in this course, we strongly recommend that students widely disseminate results to the public, such as presenting in academic conference or writing a paper for scientific journals after taking classes with advisor’s support.

How it works

  • On the first lecture (April 5th), the topics that students should take are presented. These topics are proposed by the teachers/staffs of the Hydrosphere Environmental Group, and students will choose one of them as early as possible at latest by the end of April. Though the theme setting itself is an important process of research, that process will be skipped in HSP. If a student cannot narrow down his/her interest or he/she cannot find anything interested, please contact Yoshimura. In addition, if more than one student are interested in the same topic, we will resolve the situation considerably (basically with first-come-first-served basis). Please do not choose the topic provided by the supervisor of student’s graduation research from the reason that we would like students to have a wide range of interest.
  • In HSP, there are only three occasions that all of students and advisors gather; first guidance, mid-term presentation, and final presentation. During the course, students will proceed his/her research through individual meetings with an advisor who has offered the selected topic. Sometimes we will hold seminars on common skills (programming, analysis and visualization techniques using specific software, etc.), but attendance is not essential (it does not even apply to grades).
  • On May 31st, we will hold mid-term presentation. In the mid-term presentation, please present about the background, importance, etc. of the selected topic and the subsequent research plan in about 10 minutes for each student, along with the reason for choosing the topic. Students may include the initial results that he/she has done so far, but it is not mandatory.
  • On July 12 (19th for reserve), we will hold a final presentation. In the final presentation, in approximately 15 minutes for each student, as well as the mid-term presentation, please describe the background of the topic, show the results of the analysis etc. done by him/herself, and state the conclusion based on the analysis.
  • Finally, please submit a report that summarizes a series of research work to Yoshimura and his/her advisor by 24:00 on July 31. We do not specify its amount, but a concise report is preferred than lengthy one.
  • Mid-term presentation, final presentation, and report will be in English. The language used for discussion with advisors is free.
