The news has been packed in recent months with severe climate and weather events—record-high temperatures from the Pacific Northwest to Sicily, flooding in Germany and the eastern United States, wildfires from Sacramento to Siberia to Greece. Events that seemed rare just a few decades ago are now commonplace.
A new study in the journal Nature Climate Change, looks specifically at extreme sea levels—the occurrence of exceptionally high seas due to the combination of tide, waves and storm surge. The study predicts that because of rising temperatures, extreme sea levels along coastlines the world over will become 100 times more frequent by the end of the century in about half of the more than 7,000 locations studied.
That means, due to rising temperatures, an extreme sea level event that would have been expected to occur once every 100 years (currently) is expected to occur, on average, EVERY YEAR by the end of this century.

Marine biodiversity is a fundamental characteristic of our planet that depends on and influences climate, water quality, and many ocean state variables. It is also at the core of ecosystem services that can make or break economic development in any region.
New research highlights the need for marine biological observations to inform science and conservation management and to support the blue economy.
The researchers provide ten recommendations, applicable now as part of economic monitoring efforts.

Many foundation species in chemosynthesis-based ecosystems rely on symbiotic bacteria that they take up from their environment, for their survival.
Understanding the distributions of these beneficial symbionts by region is key to understanding patterns of connectivity and predicting the resilience of the host populations.
New research attempts to shine a light on a deep-sea bacterial symbiont population structure with CRISPR. Read more at the link!

What is a nodule? In marine geology, the term usually refers specifically to manganese nodules. Manganese deposits in rings, around a fragment of some other rock or biological material, called a nucleus. When a manganese nodule is cut in half, the circular layers around the nucleus look like tree rings.
Manganese nodules were first WAY back in the 1870s. They are made primarily of manganese-oxides minerals, though they also contain high amounts of iron as well as trace amounts of cobalt, nickel, copper, and other rare metals, depending on where they form.
Because of their unique characteristics, manganese nodules found on deep sea abyssal plains have been considered for their potential as a mineral resource. In some regions of the Pacific and Indian Oceans, exploration for potential mining areas has already begun.
