German research\u00a0vessel\u00a0Polarstern has retrieved a CAGE methane sensor from 2600-meter water depth in the Fram Strait.<\/h4>\n

Text: Maja Sojtaric<\/h6>\n

<\/p>\n

CAGE deployed a methane sensor and a CTD during the RV Polarstern-expedition<\/a> to the deep- sea observatory Hausgarten<\/a> in 2015.<\/p>\n

\u201cThe main motivation for our participation<\/a> in the Polarstern cruise was to install the sensors on a deep lander at Hausgarten, and acquire long term observations of methane concentrations and variations in water masses.\u201d says PhD candidate P\u00e4r Jansson who participated in the expedition last year.<\/p>\n

Important reference site<\/strong><\/p>\n

Hausgarten is a network of 21 moorings and observatories at water depths ranging between 250 m and 5500 m in the Fram Strait<\/a>. RV Polarstern has revisited the observatory annually for the past 18 years, collecting long-term ecological data sampled by different instruments throughout the network.<\/p>\n

RV Polarstern retrieved CAGE sensors earlier this summer providing long-term observations of methane release in the Arctic Ocean.<\/p>\n

Data sampling of methane on the deep lander started on August 14th<\/sup> 2015 and the sensors were successfully recovered on June 26th<\/sup> this year, providing a long data time series.<\/p>\n

\u201d This will give CAGE researchers a better understanding of the natural yearly methane variations. The data from the central Hausgarten site will mainly serve as a reference for CAGE observatories in the shallow waters,<\/a> as the methane sensor was deployed in an area where no deep-water gas hydrate has been found and no methane seepage has been previously observed.\u201d concludes Jansson.<\/p>\n

This work was conducted within the\u00a0FixO3 project<\/a>, which seeks to integrate European open ocean fixed-point observatories.<\/p>\n","protected":false},"excerpt":{"rendered":"
