• Nutrient export from Finnish rivers into the Baltic Sea has not decreased despite water protection measures

  Open Access•Antti Räike, Antti Taskinen et al.•ARTICLE•AMBIO•2020•Citada por: 3•Referencias: 36

  Añadir item

  To tackle the symptoms of eutrophication in the open Baltic Sea and Finnish coastal waters, Finland has agreed to reduce both total nitrogen (TN) and total phosphorus (TP) inputs. Due to large investments in treatment of municipal and industrial wastewaters, TP loads started to decrease already in the mid-1970s and the respective TN loads in the mid-1990s. During the last two decades, much effort has been spent in decreasing the load originating …

• Multiple anthropogenic drivers behind upward trends in organic carbon concentrations in boreal rivers

  Open Access•Eero Asmala, Jacob Carstensen et al.•ARTICLE•Environmental Research Letters•2019

  Añadir item

  Increases of riverine organic carbon concentrations have been observed across the northern hemisphere over the past few decades. These increases are the result of multiple environmental drivers, but the relative importance of the drivers is still unclear. We analyzed a dataset of >10 000 observations of riverine total organic carbon (TOC) concentrations and associated water chemistry and hydrological observations from 1993 to 2017. The observatio…

• Concept design for a collaborative digital learning tool for film post-production

  Antti Räike, Anna Keune et al.•ARTICLE•Journal of Media Practice•2013

  Añadir item

  This article considers how and in what form a collaborative digital learning tool can contribute to the training of trainees in the field of film post-production. A concept design for such a tool is presented. The concept design was the product of a series of collaborative investigations, and the initial findings of these investigations are reported. The initial findings suggest that such a digital learning tool has the potential to qualitatively…

• Searching Efficient Protection Strategies for the Eutrophied Gulf of Finland

  An experiment combining the use of two ecosystem models was conducted to search for effective protection strategies for the Gulf of Finland (Baltic Sea). Reference and scenario simulations were first run with a one-dimensional (1D) model for seven main basins of the entire Baltic Sea until steady state was achieved. The obtained basinwise distributions of inorganic nitrogen (N) and phosphorus (P), as well as sediment labile P, were then used to i…

• Internal Nutrient Fluxes Counteract Decreases in External Load

  Añadir item

  Despite a decrease of about 30% in the external nutrient inputs, no corresponding improvement has been observed in the state of the open Gulf of Finland. At the end of the 1990s the external nutrient load to the Gulf totalled 120,000 tonnes (t) yr-1 of nitrogen (N) and 7000 t yr-1 of phosphorus (P). Relative to its surface area, the nutrient load of the Gulf is 2 to 3 times the average of the Baltic Sea. Despite the decrease in loading, an increa…
