Abstract

A modified gravity corer (MGC) for more efficient and high-quality sediment core sampling is considered. Such design elements as the core catcher, section muff joints, the weight, and loop have been modified; the crown and locking plate have been removed. As a result of comparative testing in the South Chukchi Basin of the Chukchi Sea, it is shown that the MGC sampled 30% longer cores than the standard gravity corer (SGC). Judging from the distribution of such a redox-sensitive element as iron in the cores, when the MGС is used, a surface oxidized film remains in sediments. Thus, the disturbance of properties and textures/structures of sediments under sampling is the lowest.

改良型重力取样器：优势与海上测试

摘要研究了一种改进型重力岩心取样器（MGC），以提高沉积物岩心取样的效率和质量。对岩心捕捉器、断面马弗接头、配重和环等设计元素进行了修改；去掉了冠和锁定板。在楚科奇海南楚科奇盆地进行的对比测试表明，MGC 取样的岩芯长度比标准重力取样器（SGC）长 30%。从岩心中铁这种氧化还原敏感元素的分布情况来看，使用 MGС 时，沉积物中会残留一层表面氧化膜。因此，取样时对沉积物性质和纹理/结构的干扰最小。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
