Sedimentary structures from evaporative coastal environments indicate carbonate saturation, offer insight in mid-Mesozoic ocean chemistry and potentially even earlier times.
A new study refines our understanding of marine residence times of iron, which supports carbon-sequestering sea life, offering valuable data to inform biogeochemical models.
Tiny, shelled protists known as Rhizaria may be responsible for up to one fifth of the total amount of silica produced by the world’s oceanic organisms.
A new framework for understanding the suite of processes acting on marine particulate trace metals exemplifies how alternative analyses can maximize the information that large data sets provide.
Dissolved thorium isotopes light the way to a more thorough understanding of how different elements enter marine environments—and how long they stay there.
Offsets in radiocarbon concentration within the ocean or between the ocean and the atmosphere are particularly useful proxies for a variety of studies.
A recent paper in Reviews of Geophysics discussed increasing ocean alkalinity as an alternative method of carbon sequestration in response to climate change.
Old coral colonies suggest that a prehistoric warming event called the mid-Holocene Thermal Maximum may have occurred earlier than previously thought.
