Lakes Amplify Carbon Emissions Relative to Downstream Export in Aquatic Networks

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Inland waters emit and export large quantities of carbon (C), and the balance between emission and export determines the role of inland waters in the global C cycle. Modeling studies of stream‐lake networks suggest that C emission‐to‐export ratios (emission:export) are higher in lake‐rich networks with longer network residence times (NRT), yet

Structural Analysis: Folds Classification of metasedimentary rock in the Peninsular Malaysia

IOP Conference Series: Earth and Environmental Science, 2017
Understanding shear zone characteristics of deformation are a crucial part in the oil and gas industry as it might increase the knowledge of the fracture characteristics and lead to the prediction of the location of fracture zones or fracture swarms. This zone might give high influence on reservoir performance.
