The research vessel\u00a0Helmer Hanssen spent\u00a0 3-weeks on an expedition to\u00a0seabed methane seeps <\/a>in the Arctic Ocean around Svalbard. Onboard the ship was a remotely operated vehicle (ROV) – an exploration system that can \u00a0be deployed into the depths of the ocean while operated by scientists aboard the ship to collect desired images and samples.<\/p>\n

Researchers from two Norwegian Centres of Excellence collaborated on this expedition: Centre for Arctic Gas Hydrate, Environment and Climate (CAGE) based at UiT in Troms\u00f8, and Centre for Autonomous Marine Operations and Systems (AMOS)<\/a>\u00a0\u00a0based at NTNU in Trondheim. The latter provided ROV-technology <\/a>making it possible to explore these cold seeps extensively.<\/p>\n

“The centres have cooperated to make this unique and multidisciplinary investigation possible.” says CAGE director J\u00fcrgen Mienert.<\/p>\n

Mapping the extent of the climate gas seeps<\/h2>\n

Twenty-three scientists and engineers from the two Centres conducted exhaustive mapping and sampling at methane seeping areas in Storfjordrenna and Bj\u00f8rn\u00f8yrenna.<\/p>\n

While many of these locations were already known from remote detection methods, the ROV-based surveying provided additional insight on the structure, location, and spatial extent of the gas seeps themselves and on the physical setting and biological communities surrounding them.<\/p>\n

“This unique approach has led to new discoveries on both the seeps themselves and on their impact on the local environment” says Michael Carroll, Chief Scientist of the expedition.<\/p>\n

A strong compliment to CAGE expertise<\/h2>\n

The advanced underwater technology developed through NTNU AMOS was a strong compliment to the expertise of CAGE in geology, physical oceanography, sediment geochemisty, and biology. The ROV platform provided an unpresented precision sampling in sample collection and surveying.<\/p>\n

Stein M. Nornes, PhD student at NTNU AMOS points out that the collaboration across the disciplines on scientific cruises is very inspiring.<\/p>\n

“We get to see the results of the engineering research at NTNU AMOS improving scientific data collection, and we discover new challenges to solve in order to improve our systems even further.<\/p>\n

Now that the cruise is finished the researchers have much work with data processing and sample analysis, which will probably yield yet more discoveries on these fascinating and unusual seafloor features.<\/p>\n","protected":false},"excerpt":{"rendered":"
