Methane sensor (METS) measurements at station HE537_41-1

Deep-towed methane and CTD data measured during RV Heincke expedition HE537 in the German 'Entenschnabel' area, North Sea. The methane sensor (METS) from the company Franatech was mounted at a frame (together with CTD, video cameras, forward looking sonar, altimeter and USBL transponder), which was towed 0.5 - 2 m above the sea floor at tow speeds of only 0.5 - 1 knots.

本数据集为德国海因克号（RV Heincke）考察航次HE537于北海德国所属"鸭嘴"（Entenschnabel）海区采集的深拖甲烷与温盐深仪（CTD，Conductivity Temperature Depth）数据。来自弗拉纳泰克公司（Franatech）的甲烷传感器（METS）安装于集成了温盐深仪、摄像机、前视声呐、高度计及超短基线应答器（USBL transponder）的拖曳框架之上，该框架以仅0.5至1节的低速，在海底上方0.5至2米的高度开展拖曳作业。
