Decades of research on river deltas identify gaps in our knowledge of delta behavior and the tools required to fill them in.

Reforestation as a Local Cooling Mechanism
Reforestation has been shown to cool surface temperatures, and a novel study suggests it may also reduce air temperature up to several stories above the ground.
Floating Patches of Soil Nutrients in Soil Help Explain Arctic Thawing
Nutrient-rich diapirs have a complex relationship with soil microbes and play an important role in carbon and nitrogen nutrient cycling, making them crucial for understanding feedbacks in the Arctic.
Florida Coastlines Respond to Sea Level Rise
For more than a century, carbon burial rates have been increasing on some southern Florida coasts. Scientists now verify this trend and propose an explanation.
New Models Give Global Picture of Mercury Content in Oceans
Concentrations of methylated mercury in high latitudes show the importance of sunlight and biological activity for cycling the metal.
Training the Next Generation of Marine Biogeochemists
Early-career scientists came together recently to learn to use a suite of ocean biogeochemical sensors, with the goal of closing the knowledge gap between ocean technology and potential end users.
Integrating Landscape Terrestrial and Aquatic Carbon Fluxes
Workshop on the Integration of Aquatic and Terrestrial Carbon Fluxes across landscapes; Montreal, Quebec, Canada, 9–10 May 2019
Is the Northern Permafrost Zone a Source or a Sink for Carbon?
Thawing permafrost could release large amounts of carbon into the atmosphere, but finding out how much requires better collection and curation of data.
Scientists Discover an Environment on the Cusp of Habitability
A volcanically heated Costa Rican lake hosts only one type of organism, suggesting that its Mars-like environment is just barely capable of supporting life.
Methane, Climate Change, and Our Uncertain Future
Methane is generally considered secondary to carbon dioxide in its importance to climate change, but what role might methane play in the future if global temperatures continue to rise?
