Total Inorganic Carbon

A new paper provides insights on one of the most important factors in the Southern Oceanic carbon cycle, the "biological pump," where carbon is utilized by organisms at the surface and transferred to ocean depths, away from contact with the atmosphere. The study, authored by scientists from NOAA's Pacific Marine Environmental Laboratory and the University of Hawaiʻi at Mānoa, was published in PNAS.

One of the primary drivers of climate change is excess greenhouse gases like carbon dioxide in the atmosphere. Mitigating climate change in the coming century will require both decarbonization—electrifying the power grid or reducing fossil fuel-guzzling transportation—and removing already-existing carbon dioxide from the atmosphere, a process called carbon dioxide removal.

The overturning circulation of the Pacific Ocean "flipped" during the last ice age, altering the placement of ancient waters rich in carbon dioxide, according to Earth system scientists at the University of California, Irvine.

There is a less obvious source of carbon emissions than cars and factories: rivers and streams. Inland waters release carbon in the atmosphere, but their contributions depend on their concentration of dissolved inorganic carbon (DIC) from minerals and other sources. But what factors impact DIC concentrations? A team of Penn State engineers has now determined that both water discharge—or the volume of water flowing…

The ocean's ability to absorb carbon and stabilize the climate is attracting attention from scientists and companies alike looking for ways to slow global warming.

Global warming is not just a modern issue, but has occurred numerous times over Earth's history, with one such event happening 304 million years ago during the Late Paleozoic Ice Age (which spanned from 340 to 290 million years ago). Studies have discovered evidence of increased sea surface temperature, continental ice decline and oceanic environments flooding the land at the time.

Nearly a third of Earth's freshwater resources lie in groundwater—much more than in all lakes, rivers and the atmosphere combined, and exceeded only by the frozen water in polar ice caps. Accordingly, about half of humankind depends on groundwater as a source of drinking water.

Not everything that flows into the sea is waste. "In the past, we've heard that runoff and drainage from land is bad for the ocean. Now we see that it can also be an important resource," says Juan Pardo, Ph.D. student in the Center for Coastal Research (CCR) at UiA.

Marine biologists are increasingly seeking methods to mitigate anthropogenic climate interference by implementing strategies for ocean carbon dioxide removal (CDR). Ocean alkalinity enhancement parameter is an abiotic approach aimed at carbon dioxide removal. Attempts to increase the carbon dioxide uptake capacity of the ocean can be established by dispersing pulverized mineral or dissolved alkali into the ocean…

Mike Schroepfer's Additional Ventures has spun out Carbon to Sea, a nonprofit dedicated to accelerating research into ocean alkalinity enhancement.

An experiment has reinforced the connection between contaminants. Eight years ago, the data was robust but only suggestive, and the evidence was strong but circumstantial. Recently, Karrie Weber and her team at the University of Nebraska–Lincoln have experimentally confirmed that nitrate, a comp

The Kuroshio Current enters the South China Sea via the Luzon Strait and exerts significant effects on circulation and water mass properties of this marine basin. However, limited by the few on-site observations, multi-decadal variations in Luzon Strait Transport remain uncertain.

Most people consider climate change to consist only of the warming of the atmosphere, the consequences of which primarily affect land regions. However, this is a human-centered view and does not go far enough.

Researchers at UCLA have devised a novel way of removing carbon dioxide from the world's oceans simply and affordably.

According to the IPCC, various technologies have been identified to enable and increase ocean CO2 storage. One suggested option is to store a relatively pure

Storms dominate the subpolar Southern Ocean, where upwelling CO2 drives outgassing that impacts global CO2 budget, yet how storms modify this outgassing is unknown. Here, the authors present coupled atmosphere-ocean observations to show how storm-driven ocean mixing and circulation cause substantial CO2 variability and outgassing.
