How seagrasses store carbon?
Along with being a haven for marine life, seagrass sediment is one of the planet’s most efficient carbon stores and prevents it from becoming a planet-warming greenhouse gas.
Now, researchers at the Max Planck Institute for Marine Microbiology in Bremen, Germany, a one-time coordinator of a European Union-UNEP project, have discovered how seagrasses store carbon.
The research shows that seagrasses convert organic carbon into large amounts of sugar during photosynthesis, mainly sucrose. Globally, seagrasses have produced between 0.6 and 1.3 million tonnes of these sugars. This is comparable to the amount of sugar in 32 billion cans of Coke.

Coinciding Objects (2019-2021)
rocks, shells, bones, eggshells, plaster casts, acetic acid, sediments
on view within Fotograf Festival - "Earthlings".
The exhibition “Earthlings III: Patterns” explores the possibilities of overcoming the cycle of violence and healing; extraction and growth. On the one hand, it considers patterns of environmental and racial injustice, while on the other hand, it looks up towards the autonomous power of patterns whose provenance is not in the register of human experiences and practice, but the mythological and poetic activity of objects on the threshold of the animate and the inanimate. The ability of these objects to constantly oscillate between meanings and perspectives serves as a guide to another of the principles of terrestrialness: to avoid the ’calcification’ of power relationships in our society.
Fotograf Festival - Earthlings III: Patterns is open until 7. 11. 2021 at Karlin Studios, Prvního pluku 2, Prague.
Artists: Denise Ferreira da Silva & Arjuna Neuman, Anetta Mona Chișa, Haseeb Ahmed
Curators: Lukáš Likavčan, Caroline Krzyszton
The realisation of the work was supported using public funding by Slovak Arts Council.

HEAVY METAL CONCENTRATION IN SEDIMENTS, PRAWN AND FISH FROM THE ISAKA RIVER | Journal of Global Ecology and Environment
The heavy metal concentrations in sediments, prawns, and fish (SP&F) from the Isaka River were determined in this study. Bundu, Ibeto, Macoba, and Union-Dicon were the four river stations where samples were taken. Vanadium, Chromium, Nickel, Copper, Barium, Cadmium, Arsenic, Mercury, and Lead were measured using an atomic absorption spectrophotometer. The following are the outcomes: In Bundu, SP&F, and Ibeto, Vanadium concentrations were 0.640.02, 1.440.02, and 3.942.16 mg/kg, respectively; in Ibeto, concentrations were 0.710.01, 4.793.19, and 8.061.28 mg/kg, respectively. For SP&F, Macoba showed concentrations of 0.850.02, 1.820.06, and 6.971.53 mg/kg, whereas Union-Dicon had values of 0.680.13, 1.660.02, and 7.061.19. Bundu's chromium concentrations in the SP&F were 3.110.00, 3.010.66, and 119.7420.20 mg/kg, whereas Ibeto's were 2.370.38, 3.540.75 mg/kg. 160.707.46 mg/kg and 160.707.46 mg/kg, respectively. Macoba had concentrations of 4.190.04, 4.960.59, and 143.604.72 mg/kg in SP&F, whereas Union-Dicon had concentrations of 3.850.03, 7.111.99, and 162.0613.09 mg/kg. Nickel concentrations in Bundu SP&F were 1.710.11, 5.62.36 and 29.7013.14 mg/kg, respectively, whereas Ibeto were 1.540.02, 4.620.47, and 55.7623.36 mg/kg. SP&F values in Macoba and Union-Dicon were 2.140.03, 6.721.22, and 57.484.72 mg/kg, respectively, and 1.580.04, 7.212.24, and 44.504.51 mg/kg. Copper concentrations in SP&F in Bundu, Ibeto, Macoba, and Union-Dicon were 3.200.06, 4.290.07, and 178.013.74, 4.2410.39, 7.341.50, and 230.9497.6, 4.541.23, 8.590.77, and 196.952.13 mg/kg, respectively. Bundu had concentrations of 1.510.27, 3.580.30, and 70.267.21 mg/kg in SP&F, Ibeto had values of 1.980.15, 3.340.18, and 69.912.30 mg/kg, and Macoba had concentrations of 2.490.31, 4.040.91, and SP&F concentrations were 2.790.11, 4.980.45, and 63.8713.60 mg/kg in Union-Dicon and Union-Dicon, respectively. Cadmium, arsenic, mercury, and lead were all found to be below the detection limit. The river is contaminated with heavy metals, according to the study, making the marine seafood obtained from it dangerous for human consumption.

What you really have to understand is that pix is Genuinely. Pix the nebulous character that exists in season 2 when other people and I guess Winchester are around, Is Just Some Guy. Everyone else has SOMETHING fucking weird going on, and sure Pix HAS the machine n his Dodos and he lives in the catacombs and probably sleeps in a coffin and licks rocks and shit. But he is also, Just Some Dude. That’s what you need to get, Hes some guy, and All of the Empires Rulers like this Some Guy SO MUCH that he has been added into their group chat and cannot leave. He’s stuck here, these weirdos have grown attached to him, hes meant to be writing a thesis and yet he’s being dragged into situations. He’s fighting a Eldritch horror for a Princess with an 11ft god and a Druid. These people keep asking him for the pretty glowing fruits he picks up from trees and they’re giving him magic books and stuff in return. He’s like some dude and he can’t escape what’s happening but it’s also not like he was really doing anything else

Act now to protect seagrasses by prioritising timely, ambitious and coordinated actions in the areas of conservation, sustainable management and restoratio
The importance of seagrasses is highlighted in a new report, Out of the Blue: The Value of Seagrasses to the Environment and to People, released by the United Nations Environment Programme (UNEP) together with GRID-Arendal and UNEP’s World Conservation Monitoring Centre (UNEP-WCMC).
Seagrasses are marine flowering plants that are found in shallow waters in many parts of the world, from the tropics to the Arctic circle. Seagrass meadows are of fundamental importance to nature and people. They contribute to community well-being, whether through food security from fish production, improved quality of water filtered by seagrasses, protection of coasts from erosion, storms and floods, or carbon sequestration and storage. However, seagrasses have been declining globally since the 1930s, with the most recent census estimating that 7 per cent of this key marine habitat is being lost worldwide per year, which is equivalent to a football field of seagrass lost every 30 minutes. Seagrasses are among the least protected coastal ecosystems and often face cumulative pressures from coastal development, nutrient run-off and climate change.
The message is clear. Healthy seagrasses provide a source of opportunities to mitigate climate change, adapt to future changes, build resilience and offer multiple additional societal benefits. We need to act now to protect seagrasses by prioritising timely, ambitious and coordinated actions in the areas of conservation, sustainable management and restoration.
