 こういったプロセスが、川の周辺でどんな風に起こっているのか、を調査するために、キャンプをしながら山に立ち入っています。場所は北海道の東側のある川です。学生たちは協力しながら、危険の無いように調査しました。川の周辺といっても、竹林だったりミズナラ林だったり、湿地だったりと、いろいろな植生が観察されます。こういった植生が窒素のガス化能力を変化させているのは間違いないでしょう。 どういう風に川を管理すればいいのか、ということを考えるための情報の一つとして、こういった試験は大切ですが、チームとして調査をすることで学生間に連携が生まれるのも見ていて幸せです。 Here I talk about a field study, conducted by the whole team. We study
nitrogen cycle, as mentioned earlier. Nitrogen becomes soluble to water as well
as several types of gases, and this
characteristic makes things difficult but also interesting. For example,
livestock farming without concerning the impact to the environment can
negatively impact fishery industry through nitrogen leached to rivers and
oceans. However, some of the nitrogen
becomes gas during this process (nitrogen goes from farms to ocean). We are interested in how these processes are occurring along a river. We camped and investigated the soil along the river. The river was on the eastern side of Hokkaido, and my students cooperated well, to be safe. We found bamboo trees, some broad leaf trees as well as wetlands. I am sure these different ecosystems differently influence how nitrogen becomes gases. This research is important to understand how to manage rivers. Also, I loved seeing students helping each other during this type of big field survey. |
