    Description: In the Campeche Knolls, in the southern Gulf of Mexico, lava-like flows of solidified asphalt cover more than 1 square kilometer of the rim of a dissected salt dome at a depth of 3000 meters below sea level. Chemosynthetic tubeworms and bivalves colonize the sea floor near the asphalt, which chilled and contracted after discharge. The site also includes oil seeps, gas hydrate deposits, locally anoxic sediments, and slabs of authigenic carbonate. Asphalt volcanism creates a habitat for chemosynthetic life that may be widespread at great depth in the Gulf of Mexico.

    Publication Date: 2024-01-12
    Description: 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.
