Machine learning leverages large data sets to reveal hidden patterns explaining when, where, and why dissolved organic carbon moves from hillslopes to streams.
Clues from a Subglacial Lake for Holocene Grounding Line Change
Organic carbon sampled in the lake contained radiocarbon, indicating connection to the ocean in the mid-Holocene, when the grounding line was up to 260 kilometers inland of its current position.
Bio-Argo Floats Reveal Phytoplankton Increase at Ocean Fronts
Bio-Argo floats and satellite altimeter data reveal that upwelling caused by confluent flow on the warm side of ocean fronts increases phytoplankton carbon and chlorophyll.
The World’s Roots Are Getting Shallower
Root-filled soils are hot spots of nutrient cycling and carbon storage. New research finds that the world has lost millions of cubic meters of rooted soil volume—and we’re on track to lose much more.
Una explosión de radiocarbono del pasado
El fechamiento por radiocarbono es un pilar de la climatología y la arqueología. Sin embargo, esta metodología se encuentra amenazada por las emisiones de combustibles fósiles, que invalidan una señal útil proveniente de pruebas nucleares.
Radiocarbon’s Blast from the Past
Radiocarbon dating is a cornerstone of climate and archaeological sciences. But the method is under threat as fossil fuel emissions negate a useful signal from atomic tests.
Impact of Climate on River Chemistry Across the United States
Findings of a new study have implications for water quality, aquatic ecosystem health, and water treatment and management as the world warms.
Measuring Carbon Ion Loss from the Martian Atmosphere
The flux, observed with NASA’s MAVEN spacecraft, is in line with models and 1–2 orders of magnitude lower than that of oxygen ions.
A Deep Dive into Organic Carbon Distribution in Hadal Trenches
Researchers use sediment cores to study the amount and origin of sediment organic carbon in one of the least studied regions of the planet: hadal trenches.
