           This homepage introduces "yukimarimo" that was discovered at Dome Fuji, central Antarctic
               ice sheet,  in 1995 by the members of 36th Japanese Antarctic Research Expedition.


 What is yukimarimo?

 In 1995, nine members of the 36th Japanese Antarctic Research Expedition (JARE-36) carried out the first year-round glaciological and meteorological observations at Dome Fuji Station, located at 3,810 m on the inland plateau of the Antarctic ice sheet. Members of JARE-36 observed an unusual phenomenon. Fine frost layers had formed on the snow surface at cold air temperatures (ranging from -59 to -72 °C), and frost balls had formed due to a weak wind condition.
   Dr. Kameda investigated the formation process of the balls and named them “yukimarimo”. “Yuki” means snow in Japanese and “marimo” is a ball-like plant found in some lakes in the northern hemisphere. So, yukimarimo means something like “snow ball” or “snow roller”. If you want to know more details about yukimarimo, please see Kameda et al. (1999) and Kameda (2007).

 Yukimarimo cookie first visits to his
fathers's "birth place", Dome Fuji in 2008

From November 2007 to January 2008, members of the 48th and 49th Japanese Antarctic Research Expeditions carried out the Japanese-Swedish Scientific Traverse on East Antarctic ice sheet. One of the members of the expedition (Prof. Hiroyuki Enomoto of Kitami Institute of Technology) took me to Dome Fuji. This was the first visit of my father's "birth place". These are memorial photographs. Photographs are kindly supplied by Prof. H. Enomoto of KIT, Japan.

Yukimarimo cookie's first visit to UK
in summer 2009

In August 2009, yukimarimo cookies first visited Newcastle, UK to meet world famous glaciologists.
