Last winter’s El Niño might have felt weak to residents of Southern California, but it was in fact one of the most powerful climate events of the past 145 years.If such severe El Niño events...
Beach Replenishment May Have ‘Far Reaching’ Impacts on Ecosystems
Beach Replenishment Far Reaching Ecosystems
2016/4/13
UC San Diego biologists who examined the biological impact of replenishing eroded beaches with offshore sand found that such beach replenishment efforts could have long-term negative impacts on coasta...
The Beach Book is about beaches—but also much more. An alternative title could be "The East Coast of the USA." In addition to beaches, the book covers dunes, barriers, tidal inlets and jetties, marshe...
本文对发育在澳大利亚悉尼附近的Long Reef Beach中新世古土壤剖面进行了系统的岩石磁学研究,测量了磁化率、饱和磁化强度、饱和等温剩磁、非磁滞剩磁等常温磁学参数和磁滞回线,并对所有样品进行了热磁分析.实验结果表明:全新世软土层主要磁性矿物为MD颗粒磁铁矿,磁性矿物含量与黄土高原黄土层相当.中新世老成土层随地层深度增加主要磁性矿物由磁铁矿转变为磁赤铁矿,随着磁铁矿向磁赤铁矿的转化,开始出现赤...

Once the lightest fractions of the oil had been consumed, the organisms that had been digesting those compounds declined, replaced by others able to chew up the remaining heavier materials. Ultimately...
Analysis of teleseismicPwaves with a 5200-station array in Long Beach, California: Evidence for an abrupt boundary to Inner Borderland rifting
Analysis of teleseismic waves in Long Beach, California Evidence an abrupt boundary Inner Borderland rifting
2014/4/10
We analyze teleseismicPwaves from four Mw≥6.5 earthquakes recorded by a petroleum industry survey in Long Beach, California. The survey used a 2-D array with up to 5200 seismometers, 120 m mean spacin...

Locating micro-events in Long Beach CA urban environment a dense array
2014/4/10
Micro-earthquake activity is reported for the first 6 months of 2011 in Long Beach, CA using a density urban exploration seismic network. Detected events include at least four times as many man-made e...
High-resolution 3D shallow crustal structure in Long Beach, California: Application of ambient noise tomography on a dense seismic array
High-resolution 3D shallow crustal structure in Long Beach California ambient noise tomography on a dense seismic array
2014/4/10
Ambient noise tomography has proven to be effective in resolving shallow earth structure. We applied ambient noise tomography on a dense seismic array in Long Beach, California. The array was composed...

The morphological and volumetric changes of a sandy beach were investigated through a series of two- monthly filed surveys carried out aver a 2-year period from April 2005 to January 2007. This paper ...
Variable sources of beach sands of north Adriatic islands:examples from Rab and Susak
beach sands sediment supply framework composition heavy mineral Rab Susak Croatia
2009/12/7
The composition of beach sands from the Islands of Rab and Susak (northern Adriatic) has been studied in order to determine how individual beaches are supplied with detritus. The beaches on both islan...
Natural geophysical timeseries bear the signature of a number of complex, possibly inseparable, and generally unknown combination of linear, stable non-linear and chaotic processes. Quantifying the re...
