黑珍珠的辨别     

刘丽 《黑龙江国土资源》2006,(3):54-54

当前对珍珠优化目的是提高档次，增加其经济价值。对于海水养殖珠，一般颜色的珍珠均无需改色，只有黑色珍珠因产量少，价格昂贵，所以才将浅色珍珠改成深色。  相似文献   

青岛鳌山湾海区营养结构分析与营养状况评价     

丁喜桂  叶思源  高宗军 《广东海洋大学学报》2006,26(1):22-26

根据2004年6月中旬在鳌山湾海区所取得的底层海水营养盐资料,分析了青岛鳌山湾海区营养盐的平面分布特征;运用绝对限制法则和相对限制法则确定了鳌山湾海区的营养盐限制因子;采用营养状态综合指数法和分类分级富营养化评价模式对鳌山湾海域的营养状况进行了评价。结果表明:鳌山湾营养盐限制因子为磷(P),该海区由缺氮转变为缺磷,营养盐结构发生了根本性变化,且该海域无富营养化现象,水质较好。  相似文献   

第七大洲——垃圾洲？     

《海洋世界》2008,(4):5-5

在夏威夷海岸与北美洲海岸之间，数百万吨被海水冲积于此的塑料垃圾组成了“第七大洲”。而且，顺时针流动的海水还形成了一个可让塑料垃圾飞旋的永不停歇的强大漩涡。  相似文献

千年古城西安在不知不觉中变“矮”,大雁塔可能成为“比萨斜塔”。天津塘沽地区上世纪九十年代比五六十年代海拔高度降低了3米。海河出现海水倒灌。北京有五个地区出现较大的地面塌陷,最严重的地方地表还在以每年20至30毫米的速度下沉。上海的地面以平均每年10毫米的速度下沉,有专家惊呼:再下沉2米上海将陷于汪洋之中。  相似文献   

Seasonal Phase-Locking of Peak Events in the Eastern Indian Ocean     

Qin ZHANG  Song YANG 《大气科学进展》2007,24(5):781-798

The sea surface temperature （SST） anomaly of the eastern Indian Ocean （EIO） exhibits cold anomalies in the boreal summer or fall during E1 Nino development years and warm anomalies in winter or spring following the E1 Nino events. There also tend to be warm anomalies in the boreal summer or fall during La Nina development years and cold anomalies in winter or spring following the La Nina events. The seasonal phase-locking of SST change in the EIO associated with E1 Nino/Southern Oscillation is linked to the variability of convection over the maritime continent, which induces an atmospheric Rossby wave over the EIO. Local air-sea interaction exerts different effects on SST anomalies, depending on the relationship between the Rossby wave and the mean flow related to the seasonal migration of the buffer zone, which shifts across the equator between summer and winter. The summer cold events start with cooling in the Timor Sea, together with increasing easterly flow along the equator. Negative SST anomalies develop near Sumatra, through the interaction between the atmospheric Rossby wave and the underneath sea surface. These SST anomalies are also contributed to by the increased upwelling of the mixed layer and the equatorward temperature advection in the boreal fall. As the buffer zone shifts across the equator towards boreal winter, the anomalous easterly flow tends to weaken the mean flow near the equator, and the EIO SST increases due to the reduction of latent heat flux from the sea surface. As a result, wintertime SST anomalies appear with a uniform and nearly basin-wide pattern beneath the easterly anomalies. These SST anomalies are also caused by the increase in solar radiation associated with the anticyclonic atmospheric Rossby wave over the EIO. Similarly, the physical processes of the summer warm events, which are followed by wintertime cold SST anomalies, can be explained by the changes in atmospheric and oceanic fields with opposite signs to those anomalies described above.  相似文献
