Marine geological sample data from the UK continental shelf and adjacent deep water areas (1966-)

BGS has collected approximately 33,000 offshore samples, using grab samplers, dredges and shallow coring devices (to a maximum depth of 6m below the sea bed). The data set consists of: i) The sample data sheets: these contain index information and geological descriptions of the samples. Before 1983, all data were entered on a single sheet. From 1983 onwards, the data were entered on three sheets, and therefore usually contain more detailed information than the old style data sheets. ii) Coded geological descriptions in digital format: from 1983 onwards, coded geological information regarding the descriptions were entered on data sheets. These were subsequently digitised, and information is available for about 10,000 samples in this form. iii) Sample material: the samples, cores and any remains of sub-samples are retained for further inspection and analysis. iv) Results of analyses: these are mainly short reports or single page documents resulting from analytical tests, for example, micropalaeontological examination or age dating. Digital data sets of test results (PSA, geochemistry and geotechnical) are described separately.

BGS 搜集了大约 33,000 份离岸样本，采用了抓斗采样器、挖泥船以及浅层钻探设备（最大钻探深度达海底以下 6 米）。该数据集包含以下内容：i) 样本数据表格：其中包含索引信息和样本的地质描述。在 1983 年之前，所有数据均记录在同一张表格上。自 1983 年起，数据记录在三个表格上，因此通常比旧式数据表格包含更为详尽的信息。ii) 以数字格式编码的地质描述：自 1983 年起，有关描述的编码地质信息记录在数据表格上。这些信息随后被数字化，约 10,000 份样本以这种形式提供信息。iii) 样本材料：样本、岩芯以及子样本的任何残留物均保存以供进一步检查和分析。iv) 分析结果：这些主要是来自分析测试（如微古生物学检查或年代测定）的简短报告或单页文档。测试结果的数字数据集（PSA、地球化学和岩土工程）将单独描述。
