Abstract:
On the basis of aerial photos of sea ice in the Second Chinese National Arctic Research Expdition during July and September 2003 in the area of 74.11°~79.56°N and 144.17°~169.95°W, image processing techniques are used to acquire some geometric parame...
Improved sea-ice radiative processes in a global coupled climate model
LIU Jiping, ZHANG Zhanhai, WU Huiding
2005, (6): 68-79.
Abstract:
The NASA Goddard Institute for Space Studies (GISS) coupled global climate model was used to investigate the sensitivity of sea ice to improved representations of sea-ice radiative processes:(1) a more sophisticated surface albedo scheme and (2) the ...
Characterization of the summer pack ice biotic community of Canada Basin
HE Jianfeng, CAI Minghong, JIANG Xiaodong, CHEN Bo, YU Yong
2005, (6): 80-87.
Abstract:
Summer pack ice biotic community of the Canada Basin was characterized during the Second Chinese National Arctic Research Expedition (CHINARE-2003, 20 August-5 September 2003). Bacteria, ice algae (diatoms and autotrophic flagellates) and protozoa (m...
Nutrient maximums related to low oxygen concentrations in the southern Canada Basin
JIN Mingming, SHI Jiuxin, LU Yong, CHEN Jianfang, GAO Guoping, WU Jingfeng, ZHANG Haisheng
2005, (6): 88-96.
Abstract:
The phenomenon of nutrient maximums at 70~200 m occurred only in the region of the Canada Basin among the world oceans. The prevailing hypothesis was that the direct injection of the low-temperature high-nutrient brines from the Chukchi Sea shelf (&l...
