Methane sensor (METS) measurements at station HE537_58-1

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.

在德国‘Entenschnabel’海域的北海，RV Heincke 考察船 HE537 任务期间，收集了深海拖曳甲烷及CTD（海水温度、盐度、深度）数据。此次测量所采用的甲烷传感器（METS）由Franatech公司提供，该传感器被安装在一个框架上，与CTD、视频摄像头、前视声呐、高度计和USBL应答器共同组装。该框架在拖曳过程中被维持在距离海底0.5至2米的垂直高度，拖曳速度仅为0.5至1节。
