东海北部黑潮区浮游动物的多样性研究

由于浮游动物在海洋生态系统中处于主导地位及其对生物地球化学循环和全球变化的重要影响,浮游动物与环境间相互作用的研究已成为现代海洋生态学研究的一个核心问题[1].     

北部湾三维风生流及密度流模拟

将Casulli差分格式引入三维物理海洋模型计算，模拟了北部湾风生流及密度流。模拟结果表明，夏季西南季风在北部湾导致一个顺时针环流，夏季海水密度梯度导致一个逆时针方向的环流，密度流明显强于风生流；冬季东北寒潮导致一个逆时针环流。模拟结果不支持北部湾夏季为一顺时针环流、冬季为逆时针环流的传统结论，而支持终年为逆时针环流的观点。     

A three-dimensional wave field over a bidirectionally periodic ripple bottom

For gravity wave trains propagating over an arbitrary wavy bottom, a perturbation expansion is developed to the second order so that the Bragg resonance effect of the ripple bottom on the free-surface wave can be analyzed. Both the resonant and non-resonant cases are treated and the singular behavior at resonance is avoided. This theory is successfully verified by reducing to simpler situations. Then, the analytical results for the special case of a unidirectional sinusoidal bottom are compared with experimental data for validation.

大气污染物质SO2对雾水酸度的控制作用

主要研究了青岛大气污染物质ＳＯ２对雾水酸度的控制作用，用实测结果统计得到雾得水ＰＨ值与Ｃｓｏ２的经验关系式，青岛、烟台等地雾水ｐＨ值与计算值吻合一致，表明统计关系的合理性。通过对青岛雾水中ＳＯ２清除率的估算，说明在青岛雾期，人为污染物质所占比值越高，其污染物质沉降百分率也越高，存留在大气雾中百分率就愈低。     

Cross thermocline mixing effect due to tide in the shallow sea

Using the data specially observed on the Bohai Sea oil platform by the authors for studying thermocline for two weeks, the thermocline depth, the temperature and the salinity of the layers below and above the thermocline were numerically modelled. The model is based on the Stigebrandt model and some important supplements are made in this paper in accordance with the local condition of the sea. The modelling results fit well in the observations. It is proved that the entrainmem due to both the tide and the wind can give rise to rather intense mixing cross the thermocline. This process makes the temperature rising below the thermocline,and causes the nutrient increasing above it,which has important significance for the marine physical environment and the marine organism.     

南海中北部表层沉积物的矿物沉积

本文研究了南海中北部500多个样品的矿物学。认为,本区表层沉积物中矿物种类繁多,分布较为普遍,碎屑矿物(含火山物质)、粘土矿物、自生矿物常有出现。以前者为最显著(共60多种,其中重矿物50多种,轻矿物近10种),主要分布于陆架区及深海盆;粘土矿物次之,多分布于陆坡～深海盆;自生矿物较少,陆架～深海盆均有分布。文中根据矿物沉积特征和环境差异,把它划分为6个矿物区。
