Deciphering the intensity of past ocean currents
Ocean currents determine the structure of the deep-sea ocean floor and the transport of sediments, organic carbon, nutrients and pollutants. In flume-tank experiments, researchers from MARUM—Center for Marine Environmental Sciences at the Universit.....»»
How the oceans" most abundant bacteria impact global nutrient flows
If you were to collect all the organisms from the ocean surface down to 200 meters, you'd find that SAR11 bacteria, though invisible to the naked eye, would make up a fifth of the total biomass. These bacteria, also known as Pelagibacterales, have ev.....»»
Reassessing the stability of the Florida Current: New insights from 40 years of observations
There is growing scientific interest in quantifying how large-scale ocean circulation is evolving as part of a changing global climate. Of particular interest is the potential weakening of the Atlantic Meridional Overturning Circulation (AMOC)......»»
Whales are recovering from near extinction, but industrial fishing around Antarctica competes for their sole food source
The Southern Ocean encircling Antarctica is the world's largest feeding ground for baleen whales—species like humpbacks that filter tiny organisms from seawater for food. In the 20th century, whalers killed roughly 2 million large whales in the Sou.....»»
Jellyfish under attack: Study uncovers parasitic spillover of a burrowing sea anemone
Many marine organisms, like sea anemones, struggle to spread across the ocean, especially if they lack long, mobile larval stages. Unlike their jellyfish relatives, sea anemones do not have a medusa stage, making their dispersal challenging. Their on.....»»

The case for adding iron to the ocean for carbon dioxide removal
While the urgent reduction of carbon dioxide (CO2) and other greenhouse gas emissions is needed as the primary activity to curb climate change, there is broad agreement for the need to remove CO2 already in the atmosphere. Given its outsized role in.....»»
Could comets have delivered the building blocks of life to ocean worlds like Europa, Enceladus and Titan?
Throughout Earth's history, the planet's surface has been regularly impacted by comets, meteors, and the occasional large asteroid. While these events were often destructive, sometimes to the point of triggering a mass extinction, they may have also.....»»
