A Novel Method to Determine the Grain Size and Structural Heterogeneity of Fine-Grained Sedimentary Rocks

open access: yesFractal and Fractional
Fine-grained sedimentary rocks exhibit significant textural heterogeneity, often obscured by conventional grain size analysis techniques that require sample disaggregation.

Remote sensing of the extent of the Bohai sea ice and temperature anomaly of ocean interior during recent global surface warming hiatus [PDF]

open access: yes, 2015
自1998年起,全球表面出现增暖减缓,全球气候处在深度调整中。我国近岸对此出现不同程度的响应,极端海洋灾害事件频发。2009-2010年冬季,受北方持续寒潮的影响,渤海出现了历史罕见的严重海冰冰情,海冰成为2010年中国海洋主要灾害之一。通过冰冻区遥感影像分类准确有效地提取海冰分布信息对于检测和评估海冰演化过程是至关重要的。我们提出一种新的基于融合多特征的机器学习影像分类技术,有效地用于MODIS冰冻区影像分类及海冰分布范围估算。通过灰度共生矩阵(GLCM)纹理特征分析提取MODIS影像纹理特征 ...

Conditions for the enrichment of karst hydrothermal resources in Bohai Bay Basin

open access: yesEnergy Geoscience
Drilling for karst hydrothermal resources in eastern China has posed challenges, including disparities between the temperature and yield of geothermal water. It is evident that relying solely on geothermal anomalies or indications of karst reservoirs is inadequate for the exploration of karst hydrothermal resources.
