Effort to save manatees goes underwater with planting of seagrass nursery

There is nothing quite like a beautiful day spent by the water. In some places, though, there is something dark lurking beneath the surface: human-caused pollution that is impacting creatures large and small. One program taking a hands-on approach to runoff pollution by going underwater. ....

Newly Discovered Symbiosis Could Power Carbon Removal in The Sea

Tropical rainforests are often called the lungs of our planet, sucking vast amounts of carbon dioxide from the atmosphere and puffing out oxygen in exchange. As it turns out, however, there are even bigger lungs in our oceans. ....

Effect of explosive shallow hydro... preview & related info

Abstract
Explosive volcanic submarine activity is expected to affect seagrass communities due to sudden and dramatic changes in the physical and chemical features of sea water and sediments, with possibly large ecosystem effects. However, seagrass response to the harsh environmental conditions that arise due to explosive volcanism is as yet unexplored as it is not easy to predict when and where an eruption will occur. Here, we investigate the uptake of hydrothermal carbon within the seagrass Posidonia oceanica by the analysis of Δ13C and growth rates in tissue laid down before and after an exceptional and massive hydrothermal gas release in the Aeolian Islands (Italy, Mediterranean Sea). Hydrothermal submarine activity was recorded by P. oceanica, which showed a large and persistent 13C-depletion in both scales and rhizomes in the site close to the eruption. Both increased CO2 availability and reduced carbon demand, as a consequence of stressful environmental conditions (e.g. ....

Neptune Balls: Seagrass Acts as Natural Plastic Sifters in the Ocean

Mediterranean seagrass meadow
The Posidonia oceanica, more commonly known as Neptune grass or Mediterranean tapeweed, is a seagrass species that inhabit the Mediterranean waters.
These seagrasses are known for playing a vital role in maintaining the ecosystem. They create ball like by-products made from various fibrous materials from its foliage.
These by-products are called Neptune Balls.
At first glance, these Neptune balls look like a bunch of unimportant plant dirt that serves no purpose. Once they are detached from their respective seagrasses, they just wash up to the nearest shoreline. ....
