Abstract:
The characteristics of currents and tidal currents in the Andaman Sea (AS) are studied during the second half of 2016 using observed data from a moored acoustic Doppler current profiler (ADCP) deployed at 8.6°N, 95.6°E. During the observation period,...
Relationship between a function of the northward pressure gradient and the Pacific Equatorial Undercurrent
CHEN Xuan, ZHENG Chongwei, WU Hui, YOU Xiaobao, LI Xunqiang, WANG Huipeng
2018, 37(9): 22-28. doi: 10.1007/s13131-018-1262-9
Abstract:
The Equatorial Undercurrent (EUC) plays an important role in ocean circulation and global climate change. Near the equator, as the Coriolis parameter goes to 0, equatorial currents cannot be described by geostrophy in which the pressure gradient forc...
A numerical study on the effect of tidal flat's slope on tidal dynamics in the Xiangshan Bay, China
LI Li, YE Taoyan, HE Zhiguo, XIA Yuezhang
2018, 37(9): 29-40. doi: 10.1007/s13131-018-1263-8
Abstract:
The Xiangshan Bay is a semi-enclosed and narrow bay, which is characterized by large scale tidal flats and has been historically utilized through coastal construction and aquaculture engineering. The hydrodynamic model using the Finite Volume Coastal...
A new global gridded sea surface temperature product constructed from infrared and microwave radiometer data using the optimum interpolation method
SUN Weifu, WANG Jin, ZHANG Jie, MA Yi, MENG Junmin, YANG Lei, MIAO Junwei
2018, 37(9): 41-49. doi: 10.1007/s13131-018-1206-4
Abstract:
A new 0.1° gridded daily sea surface temperature (SST) data product is presented covering the years 2003-2015. It is created by fusing satellite SST data retrievals from four microwave (WindSat, AMSR-E, ASMR2 and HY-2A RM) and two infrared (MODIS and...
An evaluation of sea surface height assimilation using along-track and gridded products based on the Regional Ocean Modeling System (ROMS) and the four-dimensional variational data assimilation
ZHOU Chaojie, DING Xiaohua, ZHANG Jie, YANG Jungang, MA Qiang
2018, 37(9): 50-58. doi: 10.1007/s13131-018-1225-1
Abstract:
Remote sensing products are significant in the data assimilation of an ocean model. Considering the resolution and space coverage of different remote sensing data, two types of sea surface height (SSH) product are employed in the assimilation, includ...

Paleoenvironmental implications of the calcium isotope characteristics in the MD81349 from the Nintyeast Ridge in the Indian Ocean
WANG Feng, FANG Nianqiao, HU Chaoyong, GOLDSMITH Sarah, XU Yonghang, DING Xuan, WANG Aijun, CHEN Ping, BAO Rui
2018, 37(9): 59-66. doi: 10.1007/s13131-018-1264-7
Abstract:
A δ44Ca curve from shells of the planktonic foraminifera Globigerinoides sacculifer in calcareous biogenic oozes has been extracted from the Nintyeast Ridge in the Indian Ocean since 300 ka. By combining terrigenous inputs (e.g., grain size, magnetic...
Smectite formation in metalliferous sediments near the East Pacific Rise at 13°N
RONG Kunbo, ZENG Zhigang, YIN Xuebo, CHEN Shuai, WANG Xiaoyuan, QI Haiyan, MA Yao
2018, 37(9): 67-81. doi: doi:10.1007/s13131-018-1265-6
Abstract:
A 43 cm long E271 sediment core collected near the East Pacific Rise (EPR) at 13°N were studied to investigate the origin of smectite for understanding better the geochemical behavior of hydrothermal material after deposition. E271 sediments are typi...
A numerical study for boundary layer current and sheet flow transport induced by a skewed asymmetric wave
