Bottom fauna in Bothnian Sea adapts to new diet

A recently published doctoral thesis shows Monoporeia affinis, a small, benthic amphipod and key marine species in the Baltic Sea, benefit from eating cyanobacteria. This is good news as cyanobacteria will both increase and spread northwards with the ongoing climate change. But the thesis also showed that amphipods living in the Bothnian Sea seem to be particularly sensitive to environmental toxins.

Plankton - important for the climate

The world’s oceans play a central role in the global climate. Wallenberg Academy Fellow Rachel Foster, Stockholm University, is researching on marine plankton communities that impact nitrogen and carbon cycles. Plankton are of extreme importance for earth’s climate. They produce half of all oxygen, lock up enormous amounts of carbon and reduce carbon dioxide. But exactly how? And how long can they continue, now as the world heats up?

Sediment bacteria important for the phosphorus turnover in the Baltic Sea

Bacteria may play an important role in the development of eutrophication in the Baltic Sea, according to a new study on organically bound phosphorus in the sediments. Thriving bacterial communities in the seabed bind phosphorus that would otherwise leak back into the water, and the presence of the bacteria in turn depend on bottom-dwelling animals mixing the sediments.

New study: Methane emissions offset carbon uptake in Baltic macroalgae habitats

Bladderwrack in the Baltic Sea emits significant amounts of methane, which, to some extent, can offset the uptake of atmospheric carbon dioxide by these algae. This is shown by a new study from Askö Laboratory, where the fluxes of greenhouse gases between surface waters and the atmosphere were measured continuously over several seasons.

Overshooting climate targets could significantly increase risk for tipping cascades

Temporarily overshooting the climate targets of 1.5-2 degrees Celsius could increase the tipping risk of several Earth system elements by more than 70 per cent. The tipping risk increases even if in the longer term the global temperature stabilizes within the Paris range. This is the result of a new risk analysis by researchers at Stockholm university published in Nature Climate Change.

Analysis: What the Kunming-Montreal Global biodiversity framework should mean for the Baltic Sea

Hurray, we have a new global framework for biodiversity and if implemented, it can make a real difference for the global environment and the Baltic Sea! Although the agreement is not legally binding, over 190 countries have signed it and have agreed to monitor and evaluate progress. More money and the possibility to measure implementation and compare countries with each other have been pointed out as the success generator for this framework as compared to the old and failed 20 Aichi targets set in 2010.

Five options for restoring global biodiversity after the UN agreement

To slow and reverse the fastest loss of Earth’s living things since the dinosaurs, almost 200 countries have signed an agreement in Montreal, Canada, promising to live in harmony with nature by 2050. The Kunming-Montreal agreement is not legally binding but it will require signatories to report their progress towards meeting targets such as the protection of 30% of Earth’s surface by 2030 and the restoration of degraded habitats.

Regulations are required to save the herring on the Christmas table

Few dishes on the table for a traditional Swedish Christmas dinner are as soaked in cultural meaning as the herring, and in the southern parts of the country also the eel. At the same time, few things are as clear examples of state-supported businesses that, like the magician in Lennart Hellsing's nursery rhyme, devour themselves like the fisheries for these species, write experts Henrik Svedäng and Charles Berkow at Stockholm University Baltic Sea Centre.

Marine ecologist Henrik Svedäng: "The eel seems to be falling victim to a culture war"

Sweden opposes the European Commission's proposal for further restrictions on fishing for the endangered eel, arguing that Swedish eel fishing is a cultural heritage. "The endangered eel is being reduced to a prop in a sentimental tableau about a soon-to-be-defunct eel fishery," says fish researcher Henrik Svedäng at Stockholm University Baltic Sea Centre.

Removing fuel subsidies to fisheries could speed up the energy transition

The Baltic Sea Centre comments on the EU Commission Call for Evidence for the initiative for the energy transition of the EU’s fisheries and aquaculture sector: A major hurdle for an energy transition for fisheries is the fuel subsidy, in the form of exemption from tax or other full carbon pricing. Another hurdle is the depleted fish stocks. Robust fish stocks make for more efficient fuel use and aid the energy transition.

Modelling key to optimising outcome of aluminium treatment

Aluminium treatment can be an efficient way to remove excess phosphorus from lakes and coastal waters. But if the external loading of phosphorus isn’t reduced, the effects of the treatment won’t last long, and monitoring and modelling are keys to optimising the results, concluded the researchers participating in last Baltic Breakfast.

The Baltic Sea oxygen debt worse than ever

The Baltic Sea suffers from serious oxygen deficiency. Even large inflows of oxygen-rich seawater have in recent decades only provided short-term relief from oxygen deficiency in the deep water. In the latest issue of Ambio, a new method for quantifying the total oxygen debt from Öresund to Åland is presented. By using existing data dating back to the 1960s, the researchers show that we have gone from a supply of about 10 million tons of oxygen in the deep water to a net oxygen supply close to zero, with an oxygen debt of up to 4 million tons caused by accumulated hydrogen sulfide and ammonium. In the last 20 years, the oxygen debt has also spread to near-halocline waters west of Gotland.

Extreme variability in coastal methane emissions could have large effects on carbon budgets

Carbon uptake by coastal ecosystems is a hot topic. The so-called ‘blue carbon’ is considered an essential part of nature-based solutions to mitigate climate change and offers opportunities for carbon trading and offset schemes. But new research on methane emissions from coastal ecosystems raises caution – the variability of these emissions is much larger than previously assumed, which implies that upscaled global carbon budgets may be far from realistic.

New study: Cod's latest crisis is not due to lack of oxygen

The crisis for Baltic cod is often associated with oxygen deficiency, oxygen-free bottoms and a lack of bottom animals that cod can eat. But now, a new Finnish-Swedish study shows that oxygen conditions have been quite adequate for cod in the southern Baltic Sea for several decades – and that there have been plenty of bottom animals above the halocline.

Baltic Breakfast: "It's a completely different sea"

The inputs of nutrients and harmful substances to the Baltic Sea have changed the distribution and composition of the animals living in and on the seafloor. But the whole ecosystem has also undergone several regime shifts during the last century. At the last Baltic Breakfast, Eva Ehrnsten and Maciej Tomczak shared their research on this topic.

Cormorant eggs – an opportunity for contaminant monitoring

The number of great cormorants in Sweden increased greatly during the 1990s and they are now a common species around the Swedish coast and many of the lakes. During the breeding season great cormorants build colonies with a distinctive fishy odor which, along with their voracious appetite for fish, has often made them unpopular. However, great cormorants could give valuable information on environmental contaminants found in aquatic environments according to a new collaborative study from the Swedish University of Agricultural Sciences (SLU), the Swedish Museum of Natural History (NRM) and Stockholm University.

Recovery from deoxygenation may be unpredictable: new study

The recovery of the oxygen-depleted bottoms in the Baltic Sea could be more unpredictable than previously estimated. New research shows that historically, the occurrence of oxygen deficiency has varied rapidly, due to an inherent instability that makes the Baltic Sea particularly sensitive to variations in climate. As the Baltic Sea recovers and approaches the goal of being unaffected by eutrophication, these sharp variations in oxygen depletion may return.

Scientists: Don’t look at the 1980's as a reference for the Baltic Sea

The photos of happy fishermen in the 1980's holding huge cods, almost larger than themselves, are iconic and often contrasted by a small meagre fishes caught today. But this period of time was an anomaly in the Baltic Sea history, and should not be regarded as a reference state, says scientists after having compiled and analysed large quantities of information from the last century.

New Article from the 2019 Ryder expedition to North Greenland

Using marine sediment cores collected during the 2019 Ryder expedition to Northern Greenland on icebreaker Oden, the Holocene retreat and advance behavior of Ryder Glacier is reconstructed. This new research shows that while Sherard Osborn Fjord has a physiography conducive to glacier and ice tongue stability, Ryder Glacier still retreated more than 40 km inland from its current position by the Middle Holocene – highlighting the sensitivity of north Greenland's marine glaciers to climate change.

Article by PhD Student Gabriel West

Establishing a solid chronological framework for Arctic marine sediments is a critical first step towards glacial and palaeoceanographic reconstructions. However, this has historically been more challenging than elsewhere in the world, and often results in core chronologies and subsequent paleoenvironmental reconstructions being questioned and overturned. Optically stimulated luminescence (OSL) dating provided important constraints on late Quaternary ages for central Arctic marine sediments, and has considerable potential to underpin chronologies in other parts of the Arctic Ocean.

Policy brief: Healthy coastal ecosystems are crucial to mitigate climate change

Treated right, coastal zones are important cornerstones in climate change mitigation, but if degraded, they instead release large amounts of greenhouse gases, re-enforcing global warming. Urgent action is needed to preserve and restore the Baltic Sea coasts and use these systems to work in favor of the climate – not against it.

Measures improve the Baltic Sea environment – even in a changing climate

A changing climate makes it even more important to reduce the nutrient supply to the Baltic Sea according to our new Policy brief. In the coming decades, continued reductions in emissions of nitrogen and phosphorus from land will yield better oxygen conditions and improved water quality – even in the face of major climate change. These measures also make the Baltic Sea ecosystem more resilient to the changing climate.

Research expedition to unexplored part of the Arctic

The marine ecosystem in the ice-covered area between Greenland and the North Pole is unexplored, but it is urgent to find out how it works. The Arctic sea ice is melting, which will radically change the ecosystem. This summer, a research expedition on board the Swedish icebreaker Oden will explore one of the world's most inaccessible places. “Nobody has ever performed these measurements there before, we are first in this giant area,” says the expedition's Chief Scientist Pauline Snoeijs Leijonmalm.

Antarctic ice sheet retreat could trigger chain reaction

The Antarctic ice sheet was even more unstable in the past than previously thought, and at times possibly came close to collapse, new research suggests. The findings raise concerns that, in a warmer climate, exposing the land underneath the ice sheet as it retreats will increase rainfall on Antarctica, and this could trigger processes that accelerate further ice loss.
