Depth profiles of dissolved and surface-bounded 224Ra as well as 228Th in near-surface sediment were determined at several sites in the Pearl River estuary (PRE) and the adjacent South China Sea (SCS) shelf.Together with 224Ra and 228Th measurements,dissolved inorganic carbon (DIC) and dissolved inorganic nitrogen (NO3+NO2,NH4+) in porewater and the overlying water were also measured.

第四纪气候旋回导致的海平面升降在陆架区留下了丰富的沉积记录及海平面和气候信息.目前第四纪研究中,对浅层高分辨地震的解释仍是重要的手段,其垂向分辨率可达分米级,足以刻画高精度的层序地层单元,乃至各种自旋回的沉积结构单元;其不足之处是地震测线间距常达数公里,横向分辨率低,难以刻画沉积体空间展布.与之相反的是石油勘探中广为采用三维地震数据,其道间距仅十几米,依靠平面切片可精细地刻画沉积体的平面展布,但其

对海底沉积物底质分类可以了解海底沉积物的不同颗粒大小、类型在海底的分布特征,进而可研究海底沉积物的物源和沉积环境等,是现今海洋工程、海洋地质和海洋环境研究的重要信息.用声呐技术进行底质分类具有工作效率高、资料连续等优点,因而是对传统的海洋地质调查手段开展底质分类技术的一种重要补充.传统的基于角度响应曲线特征分类是多波束声呐海底分类技术中的一个重要方法,但会出现分辨率较低等问题,为此,本文在其基础上
