There is no evidence that elevated methane levels have a direct impact on planktonic foraminifera and sea snails in the Barents Sea, according to a recent study in the Journal of Geophysical Research: Biogeosciences.<\/h4>\n

Text: Maja Sojtaric<\/h6>\n

<\/p>\n

First author of the study is PhD candidate Siri Ofstad from CAGE Centre for Arctic Gas Hydrate, Environment and Climate. The main finding is that there is a seasonal variation in plektonic populations in the Arctic ocean: Planktonic foraminifera and sea snail numbers swell from April to June in the Bj\u00f8rn\u00f8yrenna area of the Barents Sea. The organisms, however, do not appear to be affected directly by high methane levels from the huge blow-out craters in the area.<\/p>\n

The study was highlighted in Science News by AGU<\/a>. The article points out that methane seepage may still have an effect: \u201cThe researchers hypothesize that increased levels of methane could enhance primary production in the water column indirectly by, for example, carrying nutrients toward the ocean surface or increasing carbon dioxide levels in the water\u201d<\/p>\n

\u201cWe are flattered that they chose to highlight this seasonal study on marine calcifiers at the Bj\u00f8rn\u00f8yrenna crater area,\u00bb says Siri Ofstad.<\/p><\/blockquote>\n

\u201cAlthough we did not find a spatial or geochemical link between methane and the calcifiers, we believe there should be more research focusing on how methane affects the plankton community and trophic interactions.\u201d<\/p>\n
