Sea ice climatology of the Baltic Sea (1982-2020)
Full text link<p>This report sets out to investigate the climatology of sea ice conditions in the Baltic Sea region, with a focus on the gulfs of Riga and Finland. The analysis will be carried out by implementing climatological normals of ice days and ice extent values over a specified period of time spanning over 38 years (1982-2020).</p>

Electronic structure and defect states in bismuth and antimony sulphides identified by energy-resolved electrochemical impedance spectroscopy
No full text<p>One of the reasons chalcogenide-based photovoltaic solar cells (SC) do not yet meet the expected high-power conversion efficiencies is a lack of understanding of their electronic structure, and particularly the nature of the point defects in the absorber materials. We show that the density of states of the characteristic features of the electronic structure, such as band edges and energy distribution of defects, can be obtained experimentally by energy-resolved electrochemical impedance spectroscopy (ER-EIS) in a technically simple and quick way. The ER-EIS data correlate well with theoretical density functional theory calculations. The ER-EIS reveals that Bi<sub>2</sub>S<sub>3,</sub> has only shallow defects near the conduction band minimum (CBM). In Sb<sub>2</sub>S<sub>3</sub>, ER-EIS also shows deep defect states, which can be the cause of the low electrical conductivity of Sb<sub>2</sub>S<sub>3</sub> and lower than theoretically possible power conversion efficiency of Sb<sub>2</sub>S<sub>3</sub>-based SC. A dominant sulphur vacancy defect was identified in Bi- and Sb-chalcogenides. In the (Sb<em><sub>x</sub></em>Bi<sub>(1−<em>x</em>)</sub>)<sub>2</sub>S<sub>3</sub> ternary alloy series, a gradual transformation of CBM and defect states in the band gap was observed. Notably, a 1:9 ratio of Bi:Sb cations already transforms the deep sulphur defects into shallow ones while keeping the band edges similar to those of the pristine Sb<sub>2</sub>S<sub>3</sub>. It can provide a novel strategy for healing the deep defect states in Sb<sub>2</sub>S<sub>3</sub>, a crucial step for boosting solar cell performance.</p>

Average amount of days in the years 1993 to 2021 where coastal sea surface temperatures around Estonia are higher than 18 deg C
Full text link<p>By analyzing sea surface temperature (SST) data from Baltic Sea Physics Reanalysis datasets, a timeline of average days where coastal water temperatures were higher than a certain level can be made. In this instance, the minimum temperature was set at 18°C. Further comparisons that can be made from this data include seasonal averages for each year, the number of days with an SST of 18+ degrees that have occurred from 1993 to 2021 as well as the likelihood of having days with higher water temperatures per season.</p>
