October 2019 700 kHz multibeam echo sounder data used for Seasonal Change of Multifrequency Backscatter in three Baltic Sea Habitats

The raw data used for the study Seasonal Change of Multifrequency Backscatter in three Baltic Sea Habitats by Schulze et al.; currently under review at Frontiers in Remote Sensing. Files are stored in the s7k-Format, and sorted by date of acquisition and frequency. 200 and 400 kHz data were manufacturer-calibrated. Correct absorption values have been applied duirng the export. Refer to the paper for further dataset information. This upload stores the 700 kHz data recorded in October 2019.本研究采用的原始数据来自Schulze等人开展的《波罗的海三种生境多频后向散射的季节变化》（Seasonal Change of Multifrequency Backscatter in three Baltic Sea Habitats）研究，目前该论文正在《遥感前沿》（Frontiers in Remote Sensing）期刊审稿中。所有数据以s7k格式存储，并按采集日期与频率进行排序。其中200 kHz与400 kHz频段的数据已完成厂商校准，导出流程中已应用正确的吸收校正值。更多数据集相关细节请参阅该研究论文。本次上传的数据集包含2019年10月采集的700 kHz频段数据。
