Swath sonar bathymetry during POLARSTERN cruise ANT-VI/2 (PS12) with links to multibeam raw data files@en

Multibeam data were collected during R/V Polarstern cruise ANT-VI/2. Data recording was mainly executed in Drake Passage and Bransfield Strait and was not supervised by hydrographers. Data are unprocessed and may contain outliers and blunders. Therefore the data should not directly be used for grid calculations and charting projects but need to be edited furthermore. One file normally contains a measurement period of one day. The dataset consists of 17 files in originally Seabeam binary multibeam format (*.geo) and additionally of 17 files converted into a more common Seabeam format (*.mb14). Both datasets are compressed with GZIP to size of 7.2 MB. Seabeam data files (*.mb14) can be processed using the open source software package MB-System (http://www.ldeo.columbia.edu/res/pi/MB-System/) or the software package CARAIBES from IFREMER. […]本多波束数据采集自研究船‘极星号’（R/V Polarstern）ANT-VI/2航次。数据记录工作主要在德雷克海峡（Drake Passage）与布兰斯菲尔德海峡（Bransfield Strait）开展，且未接受水文测绘人员的监理。本数据集未经过预处理，可能存在异常值与粗差。因此本数据不可直接用于格网计算与海图制图项目，需进一步进行编辑修正。单个文件通常对应单日的测量时段。本数据集包含17份原始Seabeam二进制多波束格式（*.geo）文件，另有17份转换为更通用的Seabeam格式（*.mb14）文件。两类数据集均通过GZIP压缩，总大小为7.2 MB。Seabeam格式的*.mb14数据文件可通过开源软件包MB-System（http://www.ldeo.columbia.edu/res/pi/MB-System/）或法国海洋开发研究院（IFREMER）推出的CARAIBES软件包进行处理。 […]
