中国沿岸现代海平面变化及未来趋势分析

本文用线性回归分析方法，分１９８５年以前和１９９２年以前两个时段，对我国沿岸２５个验潮站近百年来的海平面资料进行了系统分析，计算了两个时段相对海平面变化的年速率和平均海面高度，论述了海平面变化的主要控制因素，并对未来海平面变化趋势进行了预测。计算结果表明，近百年来我国沿岸相对海平面在总体上不但持续上升，而且近年来上升速率普遍加快；根据海平面变化的主要控制因素变化趋向，预计到下世纪中叶前后，全球性海平面大幅度上升的可能性不大，我国沿岸区域性海乎面平均上升幅度不超过１５ｃｍ，不同岸段因地壳升降差异性大而有较大差别。

中太平洋CP25岩心的矿物、稀土元素及Sr、Nd同位素组成--晚新生代海底火山活动的证据

中太平洋ＣＰ２５岩心沉积物中钙十字沸石、蒙脱石／伊利石比值（Ｍ／Ｉ）、稀土元素含量、铈异常（δＣｅ）、铕异常（δＥｕ）及Ｓｒ、Ｎｄ同位素特征作为海底火山活动的证据,揭示了中太平洋海盆晚新生代以来火山活动和沉积的历史。其结果是,早中新世约２０～１７ＭａＢ．Ｐ．间,火山活动逐渐强烈,在１７ＭａＢ．Ｐ．最强烈,使得沉积物具有高Ｍ／Ｉ和∈Ｎｄ、低δＣｅ和８７Ｓｒ／８６Ｓｒ。１７～１ＭａＢ．Ｐ．发生沉积间断。１ＭａＢ．Ｐ．至现代,火山活动较早中新世减弱     

黄、东海毗邻海域悬浮体与水团的对应关系及影响因素

对黄、东海毗邻海域由陆架到深海的悬浮体进行了大量加密取样,获得了较准确的结果。给出了悬浮体含量及其三维分布,确定它们与水团及其边界有良好的对应关系。并从物源、动力和成因等解释了这种对应,提出了水团对悬浮体研究的重要意义。研究表明黑潮次—中层混合爬升水及其混合水形成悬浮体含量最低值区,横亘在陆架与深海之间,形成阻隔含有大部分悬浮体的陆架中、下层水体向深海输送的洁净“水障”,台湾暖流北上的顶托也起类似作用,并分析了影响悬浮体含量的各种因素及有关机制。     

Biokarst on Limestone Coasts, Morphogenesis and Sediment Production

Abstract. Biokarst-forms on limestone coasts are developed and arranged according to the bionomic zonation. The development of biokarst is the result of bioerosion, a synergistic effect of biological corrosion by endoliths and biological abrasion by grazers.
The cumulative effect of biogenic carbonate destruction leads to coastal destruction with a resulting highly profiled morphology on the limestone surfaces along the coastal profile. Under the influence of environmental factors a zonation of organisms develops which brings in turn a zonation of erosion rates (0.1-1.1 mm a^-1) resulting in biokarst-forms such as rock holes, rock pools and notches.
Products of bioerosion on limestone coasts are dissolved carbonate (by biological corrosion, 10–30% of the decomposed limestone) and particulate carbonate (by biological abrasion, 70–90% of the decomposed limestone) both of which contribute directly or indirectly to nearshore sedimentation. Size and shape of the bioerosional grains are determined by the boring pattern of the endoliths. The fine-grained sediments (maximum within the fraction 20–63 μm) contribute 3–25 % to the nearshore sediments.
Drastic changes in the biological zonation (like the mass invasion of the sea urchin Paracentrotus lividus in the Northern Adriatic since 1972 which eliminated nearly the entire macrophyte zone) due to unknown factors or pollution can have a profound effect on the bioerosion rates, altering them by as much as a factor of ten.

High parallelization efficiency in barotropic-mode computation of ocean models based on multi-grid boundary ghost area

In general, barotropic-mode computation requires the largest communication time in ocean models because of its iterative nature, when parallel computation is performed based on regional partitioning. In this study, reduction in the overhead time included in the communication in the parallel computation of the barotropic mode is considered to achieve a high parallelization efficiency of ocean models. We verify that the reduction in the communication frequency based on the multi-grid boundary ghost area reduces the total communication time. We find that this is because the sum of several kinds of overhead time for communication occupies a fairly large part of the total communication time. We discuss the trade-off between the decrease in communication time and the increase in computation time due to increased boundary area in such cases, leading to a determination of a suitable width of the multi-grid boundary that minimizes the total required time. We also discuss the efficiencies of the one- and two-dimensional partitioning of the model domain, when a multi-grid boundary is used. In general, two-dimensional partitioning is more efficient than one-dimensional for large partitioning numbers.
