  • The internal phosphorus load
– recycles old sins Policy Brief: The internal phosphorus load 2016-10-11 The accumulated pool of phosphorus on land receives much less attention than the pool in the Baltic Sea, despite being substantially larger and the ultimate source to the sea. Actions taken to reduce the internal load will not address the causes of eutrophication. Instead, actions must focus on improving both nutrient use efficiency in agriculture and sewage treatment.
  • Nutrient recycling in agriculture
– for a cleaner Baltic Sea Policy Brief: Nutrient recycling in agriculture 2016-10-11 Agriculture is a large source of nutrients to the Baltic Sea. Only about half of the nutrients in fertiliser and manure are converted to harvested crops. Nutrient use efficiency must improve.
  • R/V Oceania at Askö Laboratory R/V Oceania at Askö for important satellite overpass 2016-05-16 Last week several european research groups gathered at Askö Laboratory to take part in an intercalibration workshop to secure data quality of remote sensing reflectance over the Baltic Sea.
  • Sentinel-3A – the first in the two-satellite Sentinel-3 mission – lifted off on a Rockot launcher from the Plesetsk Cosmodrome in northern Russia at 17:57 GMT (18:57 CET) on 16 February 2016. Photo: ESA–Stephane Corvaja, 2016 Successful launch of Sentinel-3 - the ocean satellite 2016-02-17 ESA:s third satellite within the Copernicus mission was successfully launched from Siberia on the 16th of February. A series of satellites will be carried into orbit over the coming two decades to provide a ‘bigger picture' for the environment programme.
  • Vårutflykt till solig udde i havet Changing seasonality of the Baltic Sea 2015-12-15 Summer season in the Baltic Sea starts earlier. The number of days with sea water warmer than 17°C have almost doubled over the past 30 years. The productive season has also been prolonged. These findings are based on satellite data and the results demonstrate how such indicators of seasonality can be used to detect long-term changes.
  • BEAM Brochure Fall 2014 University Baltic Sea research in short 2015-11-24 What are the effects of brominated substances on marine wildlife? How does regulation to decrease eutrophication look in Baltic Sea countries? Why can trawling lead to toxic pollution? These are some of the issues that scientists in a large research program at Stockholm University work with.
  • Manure management in the Baltic Sea region 2015-06-22 Baltic Eye researchers Annika Svanbäck and Michelle McCrackin hosted a workshop 8 – 9 June at Kolskjulet in Stockolm to discuss manure management practices in the Baltic Sea region.
  • Klotet på Askölaboratoriet Swedish Radio about oxygen depletion 2015-04-29 A recent episode of the scientific radio program SR Klotet focused on oxygen depletion on the Baltic Sea seafloor. Three of our experts contributed with their knowledge.
  • Bacteria in the Baltic Sea reduce acidification Bacteria in the Baltic Sea reduce acidification 2014-12-15 Alkalinity production in the Baltic Sea is much larger than previously known. Researchers at Stockholm University determined the alkalinity delivered by rivers to the Baltic Sea and concluded that there are large internal sources in the sea that generate alkalinity.
  • Legal frameworks for an ecosystem-based management of the Baltic Sea Are the regulations that steer Baltic Sea management ecosystem-based? 2014-10-20 Using an ecosystem approach in managing for example fisheries and eutrophication seems to be something that most Baltic Sea countries strive for, but how is that implemented in the binding laws and regulations? To illuminate that was the purpose of the conference Towards an ecosystem-based legal framework for the Baltic Sea held at Stockholm University on October 7th 2014.
  • Cyanobacterial bloom in the Baltic Sea July 11, 2005 Cyanobacterial summer blooms progressively earlier in the Baltic Sea 2014-07-08 The cyanobacterial summer bloom in the Baltic is now almost three weeks earlier than 35 years ago, according to a study published in Biogeosciences. The blooms had been predicted to become earlier in the future, as a result of climate change, but now it appears that the future is already here.
  • 10-fold increase of 'dead zones' in the Baltic Sea 2014-04-02 Baltic Nest Institute researchers and their international colleagues report that the dead zones in the Baltic Sea have increased 10-fold over the last 115 years, growing from approximately 5 000 km² in 1900 to more than 60 000 km² in recent years. The study is published 2014 in PNAS, Proceedings of the National Academy of Sciences.
  • Retention in South Baltic river basin district, by Andrew Quin Landscape-scale effect of wetlands in reducing nutrient loads to the Baltic Sea 2013-12-06 The Baltic Sea is heavily impacted by eutrophication due to excessive nitrogen and phosphorus loading from various anthropogenic sources. Protection, restoration and creation of wetlands are often proposed as a solution, but scientists at Stockholm University now warn that the effect of wetlands on nutrient retention is undetectable at landscape-scales.
  • Marine resource management - an explanation 2013-04-08 To find out we asked a long-time expert a few questions: How are marine resources managed in Sweden? What are some important decisions that have been made? What is needed in the future?
