Virgin rock temperatures from well logs — accuracy analysis for some advanced inversion models

Temperature data from 18 measurement series obtained during logging of the Oseberg field in the northern North Sea are presented. Because the measurement series are taken at approximately the same depth, they should give identical temperatures after depth correction, and are suitable for assessing the performance of different models used to determine virgin rock temperatures from well log information.We have used this data set to test the properties of the different models given by Shen and Beck (1986). Although these models were built to simulate closely the thermal recovery of a well and are unbiased, the uncertainties in the temperature estimates when applied to real data are found to be no less than those from simpler (biased) models. This fact confirms the conclusion of Hermanrud (1989a) who showed that physical factors other than those presently accounted for significantly influence the thermal recovery of a borehole.     

One new species of free-living marine nematodes (Enoplida,Anticomidae, Cephalanticoma) from the Huanghai Sea

One new species of free-living marine nematodes Cephalanticoma filicaudata sp. nov. from the Huanghai Sea, China is described and illustrated. Cephalanticoma filicaudata sp. nov. is characterized by well developed cephalic capsule, three teeth at the anterior of oesophagus, excretory pore opens posterior to cervical setae, only two cervical setae per file, body length longer than 5 200 μm, tail long and no ventral-lateral seta between the supplement and the cloacal opening. Types are deposited in the College of Marine Life Sciences, Ocean University of China.

中国沿岸水域养殖贝类及其养殖笼网污损苔虫7新种

拟小孔苔虫属Microporella和斑孔苔虫属Fenestrulina均隶于唇口目Cheilostomida有囊亚目Ascophorina皮壳次目 Lepraliomorpha裂孔超科Schizoporelloidea拟小孔苔虫科Microporellidae。这两个属的主要区别在于：拟小孔苔虫属具有鸟头体，而斑孔苔虫属无鸟头体。我们在研究中国沿岸水域养殖贝类及其养殖笼网的污损苔虫时发现，中国一些学者以前所报道的“纤毛拟小孔苔虫”并非 Pallas(1766)所鉴定的种，而是包括不同于纤毛拟小孔苔虫Microporella ciliata Pallas，1766的5个不同的独立种，即本文所描述的拟小孔苔虫属的5个新种：空穴拟小孔苔虫 Microporella vacuatus sp.nov.、小筛网拟小孔苔虫Microporella cribellata sp.nov.、无齿拟小孔苔虫Microporella inermis sp.nov.、异北方拟小孔苔虫 Microporella antiborealis sp.nov.和项链拟小孔苔虫 Microporella monilifera sp.nov.。这5个新种与纤毛拟小孔苔虫的主要区别是:5新种的口刺为2~6根，除无齿拟小孔苔虫的口上卵胞仅具一列边缘孔外，其他4新种卵胞前表面还有分散的穿孔；而纤毛拟小孔苔虫的口刺为6根，口上卵胞细颗粒状，无穿孔。研究中我们还发现前人所定名为“马氏斑孔苔虫”的种并非 Audouin(1826)所描述的种，而是4种不同于马氏斑孔苔虫 Fenestrulina mallusii Audouin，1826的独立种，其中两种不属于污损苔虫的范畴，另外的两种即本文所描述的斑孔苔虫属的两新种，即中华斑孔苔虫Fenestrulina Sinica sp.nov.和东方斑孔苔虫Fenestrulina orientalis sp.nov.。这两个新种与马氏斑孔苔虫的主要区别在于：两新种口刺均为4~6根，受孕个虫有2根裸露的口刺；而马氏斑孔苔虫的口刺为2~3根，受孕个虫无裸露的口刺。     

区域海洋地质数据库建设纲要

区域海洋地质数据库是中国地质调查局基础数据库的一个重要组成部分，是实现地质调查基础性与公益性战略部署的依托。根据区域海洋地质数据库建设的目标与任务，在数据结构和实施步骤等方面进行了初步研究。区域海洋地质数据库及其管理信息系统适合采取基于Web系统的三层体系结构，在数据构成上亦分为区域海洋地质调查原始资料与成果资料，其中元数据库的建设对数据库的应用非常重要，用户可以通过元数据了解数据的存在性、适宜性、有效性等，确定数据的使用方法，因此，元数据库的建设应采用国际已经普遍认可的ISO/TC211发布的ISO19115空间元数据标准。     

Wind-driven interannual variability over the northeast Pacific Ocean

Interannual variability of the sea surface height (SSH) over the northeast Pacific Ocean is hindcast with a reduced-gravity, quasi-geostrophic model that includes linear damping. The model is forced with monthly Ekman pumping fields derived from the NCEP reanalysis wind stresses. The numerical solution is compared with SSH observations derived from satellite altimeter data and gridded at a lateral resolution of 1 degree. Provided that the reduced gravity parameter is chosen appropriately, the results demonstrate that the model has significant hindcast skill over interior regions of the basin, away from continental boundaries. A damping time scale of 2 to 3 years is close to optimal, although the hindcast skill is not strongly dependent on this parameter.A simplification of the quasi-geostrophic model is considered in which Rossby waves are eliminated, yielding a Markov model driven by local Ekman pumping. The results approximately reproduce the hindcast skill of the more complete quasi-geostrophic model and indicate that the interannual SSH variability is dominated by the local response to wind forcing. There is a close correspondence the two leading empirical orthogonal modes of the local model and those of the observed SSH anomalies. The latter account for over half of the variance of the interannual signal over the region.
