Downward continuation of aeromagnetic data to the marine surface
XU Shizhe, WANG Rui, ZHOU Jianxin, XIAO Pengfei, CHEN Shengchang
2008, (1): 54-60.
Abstract:
The existing methods of downward continuation of potential field cannot be used to continue the aeromagnetic data to the marine surface because of the limited continuation distance. An iteration method for the downward continuation of potential field...
Two new species of Eirenidae from the coast of southeast China
GUO Donghui, XU Zhenzu, HUANG Jiaqi
2008, (1): 61-66.
Abstract:
Through the examination of 377 samples collected from the Taiwan Straits, two new species of Eirenidae, i. e., Eirene octonemalis n. sp. and Eutima krampi n. sp. are described. All type specimens are deposited at the Department of Oceanography, Xiame...
Potential impacts of Three Gorges Dam in China on the ecosystem of East China Sea
WANG Baodong, BROCKMANN Uwe
2008, (1): 67-76.
Abstract:
The Changjiang River in China was dammed in 2003. The possible changes in matters fluxes from the river downstream after the completion of Three Gorges Dam and their potential impacts on the ecosystem of the East China Sea are discussed.The estuarine...
Chlorophyll a and primary production in the northeastern Pacific Ocean
CHEN Xingqun, LIN Rongcheng
2008, (1): 77-84.
Abstract:
The primary production and chlorophyll a concentration of picoplankton (0.2~2 μm), nanoplankton (2~20 μm) and microplankton (20~200 μm) are described in the northeastern Pacific Ocean near the Hawaii Islands during the six survey cruises from 1996 to...
