The temperature sensitivity of soil organic carbon decomposition is greater in subsoil than in topsoil during laboratory incubation

open access: yesScientific Reports, 2017
The turnover of soil organic carbon (SOC) in cropland plays an important role in terrestrial carbon cycling, but little is known about the temperature sensitivity (Q 10) of SOC decomposition below the topsoil layer of arable soil.

Study on the Spillover of Sediment during Typical Tidal Processes in the Yangtze Estuary Using a High-Resolution Numerical Model

open access: yesJournal of Marine Science and Engineering, 2019
Because of special morphologies and complex runoff−tide interactions, the landward floodtide flows in Yangtze Estuary are observed to spill over from the North to the South Branches, carrying a lot of sediment.

Effects of annual flow characteristics on the freshwater life history of Chinese sturgeon: concern inferred from the number of seaward migrating juveniles [PDF]

open access: yes, 2012
Since 2003, the flow characteristics of the Yangtze River, currently the only river where the protected Chinese sturgeon, Acipenser sinensis, spawns and where the young grows to the 6 to 8 month juvenile stage, has been regulated by the operation of the ...

The thermal response of soil microbial methanogenesis decreases in magnitude with changing temperature

open access: yesNature Communications, 2020
Soil microbes produce more methane as temperatures warm, but it is unclear if they acclimate to heat, or keep producing more of the greenhouse gas. Here the authors use artificial wetland warming experiments to show that after initial spikes in methane ...

129I and its species in the East China Sea: level, distribution, sources and tracing water masses exchange and movement [PDF]

open access: yes, 2016
Anthropogenic I-129 as a long-lived radioisotope of iodine has been considered as an ideal oceanographic tracer due to its high residence time and conservative property in the ocean. Surface water samples collected from the East China Sea (ECS) in August

Response of nearshore circulation outside Yangtze Estuary to El Niño events

open access: yesWater Science and Engineering, 2016
With consideration of the comprehensive effects of runoff from the Yangtze River, East China Sea background circulation, and tidal currents, a regional circulation model, including the Yangtze Estuary, Hangzhou Bay, and adjacent sea areas was established.
