In the February issue of Eos, we dive deep to better understand opportunities, challenges, and ongoing mysteries posed by carbon’s role in marine environments.
Oceans
Bottom Trawling Shreds the Seafloor. It May Also Be a Huge Source of Carbon Emissions.
Dragging nets along the ocean bed wrecks marine life, but researchers can’t agree on how bad it is for the climate.
Compound Extreme Events Threaten Marine Ecosystems
Short-term extreme marine heat wave events superimposed on stressors from longer-term climate change produce compound extreme events that impact the Gulf of Alaska ecosystem.
In the Great Pacific Garbage Patch, New Marine Ecosystems Are Flourishing
Sea life, stuck to plastic bottles and other human trash, has journeyed far from coastal habitats—and may threaten local species
The Importance of Archiving the Seafloor
Marine geological sample repositories are vital for ocean science, climate change studies, and more. The value of their collections is growing amid efforts to meet rising demand for their services.
Overturning Ocean Water by Turbulence
A high-resolution regional model of the Southern Ocean reveals how topographically induced mixing in the abyss is important in creating the water masses that can upwell back up to the surface.
How Nutrients Get Back Up to the Surface Ocean
A new dual isotope tracer technique is used to assess the role of a number of poorly understood nutrient supply mechanisms fueling biological productivity in the ocean.
Scientists Investigate How Heat Rises Through Europa’s Ocean
A new study examines how heat may be transferred from the mantle, through the ocean, and into the icy crust of one of Jupiter’s moons—perhaps among the most promising places in our solar system to search for life.
Seawater Dynamics in an Underexplored Antarctic Fjord
Wind is the major driver of salinity changes within the narrow, glacier-fed cove.
