The College of Gothenburg has sent three submerged robots into the Baltic waters around the holes of the Nord Stream gas pipeline. This is to have the option to follow how science and life in the ocean change after some time because of the huge arrival of methane gas. Moreover, the research vessel Skagerak is set to sail on another campaign to the Baltic Ocean to trial the huge, automated vessel Ran.
The campaign with R/V Skagerak was not, by any means, the only measure the college’s analysts took when the Nord Stream pipelines started to spill methane gas. With the assistance of the Voice of the Sea establishment, VOTO, three remote-controlled submerged robots were set nearby. They will move around the ocean and record water information constantly for the next 15 weeks.
They are called “lightweight flyers” and are given by VOTO, who likewise deals with their activity. “The robots can give us estimations over a progression of time about what the science and nature of the water is meant for by the petroleum gas spill,” says oceanographer Bastien Queste at the College of Gothenburg.
There is a lot of information from the area.
Since Walk 2021, VOTO has had two lightweight planes in the space with the same capabilities as one of the establishment’s sea observatories and where the water quality is estimated to be constant. The robots go down to the base and, afterward, go up to the surface, something rehashed over a preset distance. Each time the lightweight plane is at the surface, the most recent estimation information is shipped off to the analysts through satellite. Hence, a lot of information from this area currently exists from previously. One of the three extra robots that were dropped into the ocean last week has been prepared by the maker Alseamar with a unique sensor to have the option to gauge the adjustment of the methane content throughout the next 15 weeks.
“They are known as gliders, and they are supplied by VOTO, which also manages their operation. The robots can provide us with measurements over time regarding how the natural gas leak affects the chemistry and quality of the water.”

Last week’s campaign gave important information and a preview of the condition of the sea following the spillage. With the new robots set up, we get nonstop reports on the condition of the water close to the Nord Stream pipeline spills. “They are sent exclusively for this reason,” says Bastien Queste.
“The fact is that we get estimations from the water over an extensive stretch of time and over a larger region. We can perceive what amount of time it requires for the methane to vanish and how the oceanic climate responds over the long haul. The reaction in the ocean is frequently delayed. It might require days or weeks before we see a change, “says Bastien Queste.

Indeed, even the submerged robots that are normally sent there can contribute significant information as they measure saltiness, temperature, oxygen content, and how much chlorophyll there is. This completes the image of how the water in the Baltic Ocean is doing after the gas spill.
Strong logical documentation
“Along with the new robots and the endeavor’s estimations, we analysts will have strong logical documentation of the effect of the Nord Stream spill. When we consider the whole, we have a decent image of both the quick and the delayed impacts. “With lightweight flyers that constantly measure, we will actually want to more readily comprehend the cycles that were noticed then,” says Bastien Queste.
The campaign has had the opportunity to land before arrangements for the following outing to the Baltic Ocean with Skagerak have begun. Polar scientist Anna Whlin had, for quite a while, arranged an outing with the boat exactly to the area east of Bornholm.
“I will test how the huge submerged robot Ran acts in oceans with enormous layers of thickness and how well it can gauge over silt-rich bottoms. This spot is ideal for that. “Ran can likewise add to examination of gas outflows since it estimates the carbon dioxide and nitrate levels in the water,” says Anna Whlin. This is likewise whenever Ran first leaves Skagerak, which will be a significant test of the boat’s adaptability.
