Heterogeneous reservoirs in the marine carbon cycle [PDF]

, 2014
Understanding the fate of primary production in the ocean is a challenging task because once produced, organic material is oxidized over timescales which range from minutes, to millions of years. This timescale diversity is matched by an equal heterogeneity in both the local physical and chemical environment.

Improving the Satellite-Based Winter Wheat Monitoring by Using UAV-Derived Leaf Chlorophyll Content

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Mapping regional leaf chlorophyll content (LCC) still faces challenges of the scale mismatch between ground sampling points and satellite pixels. To improve the satellite-based model, this study explored the potential of using high-resolution unmanned ...

Global Wetland Methane Emissions From 2001 to 2020: Magnitude, Dynamics and Controls

Earth's Future
The large uncertainties in estimating CH4 emissions from wetland ecosystems, the leading natural source to the atmosphere, substantially hinder the quantification of the global CH4 budget.

Oceanic carbon cycle in a symbiotic zone between hydrothermal vents and cold seeps in the Okinawa Trough

Geosystems and Geoenvironment, 2022
Submarine cold seeps and hydrothermal vents are the key agents of material and energy exchange between the marine lithosphere and outer geospheres. Moreover, they breed natural gas hydrates, massive metal sulfides, and precious genetic resources and are ...

Need for monitoring and maintaining sustainable marine ecosystem services [PDF]

, 2014
Increases in human population and their resource use have drastically intensified pressures on marine ecosystem services. The oceans have partly managed to buffer these multiple pressures, but every single area of the oceans is now affected to some ...

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

FEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Marine Biopolymer Dynamics, Gel Formation, and Carbon Cycling in the Ocean [PDF]

Gels, 2021
Much like our own body, our planet is a macroscale dynamic system equipped with a complex set of compartmentalized controls that have made life and evolution possible on earth. Many of these global autoregulatory functions take place in the ocean; paramount among those is its role in global carbon cycling.
