浅谈海洋环境监测工作及其质量管理关键环节

随着我国海洋开发力度的不断加大,党的十八大提出了"建设海洋强国"的战略目标,海洋环境监测任务逐渐加重。结合多年海洋环境监测的实践,浅谈海洋环境监测工作及其质量管理的关键环节,以期为海洋环境监测工作质量的提高提供参考。     

基于多源融合卫星高度计观测数据的南海海浪有效波高的季节变化研究

The seasonal variability of the significant wave height(SWH) in the South China Sea(SCS) is investigated using the most up-to-date gridded daily altimeter data for the period of September 2009 to August 2015. The results indicate that the SWH shows a uniform seasonal variation in the whole SCS, with its maxima occurring in December/January and minima in May. Throughout the year, the SWH in the SCS is the largest around Luzon Strait(LS) and then gradually decreases southward across the basin. The surface wind speed has a similar seasonal variation, but with different spatial distributions in most months of the year. Further analysis indicates that the observed SWH variations are dominated by swell. The wind sea height, however, is much smaller. It is the the largest in two regions southwest of Taiwan Island and southeast of Vietnam Coast during the northeasterly monsoon, while the largest in the central/southern SCS during the southwesterly monsoon. The extreme wave condition also experiences a significant seasonal variation. In most regions of the northern and central SCS, the maxima of the 99 th percentile SWH that are larger than the SWH theoretically calculated with the wind speed for the fully developed seas mainly appear in August–November, closely related to strong tropical cyclone activities.Compared with previous studies, it is also implied that the wave climate in the Pacific Ocean plays an important role in the wave climate variations in the SCS.     

基于ArcGIS的倾倒区水深地形冲淤变化分析

东碇临时海洋倾倒区是当前福建省内使用频率最高、倾倒量最大的海洋倾倒区,自2010年重新投入使用以来,该倾倒区共接纳了约1.5×107 m3的疏浚物,为研究其海底地形冲淤变化情况,利用ArcGIS的空间分析模块、3D分析模块、地统计分析模块等对东碇临时海洋倾倒区进行冲淤变化分析,文中介绍了冲淤分析的基本流程并对分析结果进行讨论,说明疏浚物倾倒对水深地形的影响程度。
