地震分析软件震相走时表文件结构研究

通过对现有地震分析软件所配置的震相走时表文件的结构类型及优劣进行分析,将震相走时表分为4种组合结构并分析其实用性。在IASPEI91震相走时表文件结构的基础上进行修改、补充和完善,从而提出了一种安全性高、适用面广、灵活性强、能存储各种结构走时表的新型走时表文件结构。应用这种新型结构震相走时表,地震分析软件可以灵活配置不同的走时表,实现精细定位,并为数字化测震台网快速利用测震资料编制和应用高精度的区域震相走时表创造了条件,对于地球深部构造研究具有一定的促进意义。     

Ecological periodic tables for benthic macrofaunal usage of estuarine habitats in the US Pacific Northwest

This study shows that spatially and temporally recurring benthic macrofauna-habitat patterns validate the ecological relevance of habitat types to benthic macrofauna and suggest they can serve as elements in ecological periodic tables of benthic macrofaunal usage. We discovered patterns across nine habitat types (intertidal eelgrass [Zostera marina], dwarf eelgrass [Zostera japonica], oyster [Crassostrea gigas] ground culture, burrowing mud shrimp [Upogebia pugettensis], burrowing ghost shrimp [Neotrypaea californiensis], shell, sand, mud, and subtidal) on a variety of benthic macrofaunal community state variables in Grays Harbor, Washington, USA and compared them to those in Willapa Bay, Washington, USA. There were nominal differences in benthic macrofaunal Bray-Curtis similarity between all the habitats investigated except eelgrass and oyster in both estuaries. Across-habitat patterns on mean benthic macrofaunal species richness, abundance, biomass, abundance of deposit, suspension and facultative feeders, a dominance and a diversity index for the five habitats common to both studies were the same on a rank measurement scale: eelgrass ≈ oyster > mud shrimp > ghost shrimp ≈ subtidal. The patterns for most of the habitats and benthic macrofaunal measures were the same on a ratio measurement scale.
