MARC recordEvidence for active microbial nitrogen transfers in sea ice (Gulf of Bothnia, Baltic Sea) in midwinter / Hermanni Kaartokallio.
| Title: | Evidence for active microbial nitrogen transfers in sea ice (Gulf of Bothnia, Baltic Sea) in midwinter / Hermanni Kaartokallio. |
| Author(s): | Kaartokallio, Hermanni. |
| Date: | 2001. |
| In: | Polar Biology. (2001.), Vol. 24(1) (2001) |
| Abstract: | Nutrient concentrations, chlorophyll-a, bacterial biomass and relative activity of denitrifying organisms were investigated from ice core, brine and underlying water samples in Feb. 1998. In 2-3 months old ice communities were at winter stage, chl-a concentrations were below 1 mg m⁻³ and heterotrophic organisms composed 7-20% of organism assemblage. In 1-month old ice, spring bloom was developing and chl-a concentrations were up to 5.6 mg m⁻³. In relation to low salinity, high concentrations of nitrogen and phosphorus compounds were found in ice column. |
