Methane sensor (METS) measurements at station HE537_51-1

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.
