章节大纲

    • We measure as many basic parameters of ocean chemistry as possible.

      Seawater components：dissolved oxygen, total carbonate, alkalinity, nutrients (five components), organic gas components (halocarbons, isoprene, of which methane is included)

      Particle components： diatom suspensions during diatom bloom (vertically collected with NORPAC Net)　→　Carbon, nitrogen, phosphorus, silicon (of which, iodine is also included)

      Sediment components： nutrients, organic gas components, carbon, nitrogen, phosphorus, silicon

       

      For the time being, we measure everything we can. Though we have not fully analyzed everything…
      （This paper focuses on the analysis of organic gas components, which is the main research theme. Of these, carbon, nitrogen, and silicon are included）


    •  Photobook of observations at Funka Bay (some include links to LASBOS YouTube)





      A large amount of diatom aggregate is collected and used for the decomposition culture experiments. We always receive the cooperation of members of the Fisheries Science Group. Thank you.



      This is a sediment sample.




      We attempted to investigate the chemical environment of sediments and the state of benthic organisms. 



      Ashura sediment core sampler. This can collect three sediment core samples at a time.



      The landscape looks beautiful during winter. This is Mt. Yotei.



      The picture below shows a sample treatment where the pore water is sucked out on board the Ushio-Maru.

      Mr. Miyashita (left) was recording observations with a runny nose like a little kid.




      The top two students who conducted the Funka Bay observations. They have both found jobs at an environmental consulting firm.



      The dining scene at Ushio-Maru. We want to eat seafood curry on every voyage!



      CTD rosette sampler on Ushio-Maru. A miniature size around this scale is easier to use.

      Observations from around ten years ago. Professor Emeritus Kuma (right) stood on the front lines of the observation process until just before his retirement.



      Water is sampled in narrow spaces.
