KH11-1航海報告 No. 1 オーストラリア巡検

横山研M1の坂下です。
たいへん遅くなりましたが1/18〜2/9までのKH11-1航海の報告をさせて頂きます。

まず船(白鳳丸)に乗る前に先遣隊として
窪田、中村、坂下のM1の３人とスティーブ(PD)でオーストラリアに一足先にいきました。
その際、前のlegの高知大学の方々と一緒にオーストラリア巡検を行いました。

１日目はワイン巡検を行いました。

みんなワインをおおいに堪能いたしました！！
ワインを堪能した後、マーガレットリバーのホテルで１泊しました。

2日目は本格的にCave巡検を行いました。

中村さんのテンションが非常に高かったのが印象的でした。
Cave巡検のあと、Cape leeuwinという南大洋とインド洋の境界に位置する岬に行きました。

非常にスケールの大きな風景が印象的でした。

全体的な感想として自分は今回が初海外だったこともあり
体験する全てのことが自分にとって刺激になることばかりでした！！
No.2につづく・・・

Nagasaki

My first trip outside Tokyo since I am in Japan was to visit the Nagasaki region. 

The three days trip was divided in a day of field excursion, a day at the University of Nagasaki and the last day to visit the Nagasaki city.

The first day I took part of a field excursion held at the end of the international symposium on the sustainability and productivity of coastal resources. I had the chance to visit Isahaya dike gate, Unzen Jogoku, the Nita ridge observatory and the Mt. Unzen Disaster Memorial Hall.

The Nita observatory and the Mt Unzen Memorial Hall were very interesting to understand what is the life near an active volcano.

The second day I visited Prof. Yu Umezawa laboratory at the University of Nagasaki. The aim of the visit was to make some tests on his RaDeCC system. The RaDeCC system is used to measure short half-life radium isotopes (²²³Ra and ²²⁴Ra).

Finally, I visited Nagasaki city and in particular the Atomic bomb museum and his Memorial Hall.
