Population Connectivity and Larval Dispersal Using Geochemical Signatures in Calcified Structures
Population Connectivity Larval Dispersal Geochemical Signatures Calcified Structures
2015/7/22
The importance of larval dispersal to the population dynamics and biogeography of marine organisms has been recognized for almost a century (Hjort, 1914; Thorson, 1950). More recently, theoretical stu...

2017/8/9
The petrography as well as major, trace and rare earth element (REE) compositions of Mesoarchaean Naharmagra quartzite of Aravalli Craton have been investigated to determine influence of sorting and r...
Evidence for geochemical control of iron by humic substances in seawater
geochemical control iron by humic substances in seawater
2014/4/17
A new method, based on the direct detection of iron-humic substance (HS) species by cathodic stripping voltammetry (CSV), is used to determine the iron binding capacity and complex stability of fulvic...

Geochemical controls on anaerobic organic matter decomposition in a northern peatland
Geochemical controls anaerobic organic matter decomposition northern peatland
2014/4/18
The decomposition of deep peat deposits controls the long-term carbon balance of peatlands but is poorly understood with respect to rates and controls. To rectify this deficiency, we estimated in situ...
