20180275311 | METHOD FOR DETECTING GLACIER MELTING BASED ON TRACER TECHNOLOGY - The present invention discloses a method for detecting glacier melting based on tracer technology. The method includes the following steps. 1. Different tracer agents with equal concentration are respectively added into a plurality of water samples. The water sample and the tracer agents are mixed well. Meanwhile, the volume and the mass of each glacier model are recorded. A plurality of water samples added with tracer agents are frozen layer by layer from inside to outside to establish a plurality of glacier models. 2. The surrounding environmental factors of the glacier model are adjusted. Water samples of the glacier models melted under different environmental factor conditions are collected. Furthermore, the concentrations of different kinds of tracer agents in the water samples are measured. | 2018-09-27 |
20180275312 | CONSTRUCTING STRATIGRAPHIC IMAGES OF SEDIMENT DISTRIBUTION IN A SUBSURFACE OF THE EARTH - A distribution of sand sediment class in a subsurface of the Earth is identified. Three-dimensional stratigraphic images of sediment distribution in a subsurface of the Earth are constructed, including at least two depositional domains, by simulating sediment transport and deposition over a selected time interval of sediments originating from one or more clastic sediment input sources. The simulation uses at least two equilibrium surfaces bounding the at least two depositional domains and at least two sediment classes, and updates the equilibrium surfaces in a sequence of timesteps, by accounting for sediment feed from the one or more clastic sediment input sources, erosion and deposition in accordance with mass-balance equality constraints. The images are used to identify a distribution of sand sediment class in the subsurface of the Earth suitable for acquiring hydrocarbons or fresh water, or for storing gas or liquids. | 2018-09-27 |
