Abstract Plant wax hydrogen isotopes (δ2H) preserved in lake sediments provide valuable insights into past climatic changes. However, lake catchments often experience local shifts in vegetation type that can yield distinct isotopic signatures in the sediments, potentially obscuring hydroclimatic signals.

Atmospheric fluxes of radionuclides on monthly time-scale in Málaga (Spain) [PDF]
.- Bulk atmospheric deposition of gamma radionuclides ( 7Be, 210Pb and 40K ) has been measured at Málaga (4º 28´80′′ W; 36º 43′ 40′N) at a coastal Mediterranean station in the south of Spain, from January 2005 through December 2012 for monthly ...

Bioturbation experiments in the Venice Lagoon [PDF]
Short experiments (14–21 days) were carried out during autumn 1998 and spring 1999 at one selected site of the Venice Lagoon to measure bioturbation activities and mixing rates, as well as to obtain quantitative information on benthos functionality ...

This study reveals unprecedented burning in tropical peatlands during the 20th century, mainly expressed in the Indomalayan and Australasian regions, emphasising regional variability in peatland burning and its links to modern human activities. Before this period, tropical peatland burning largely followed changes in global temperature and was ...

Abstract Coastal hypoxia is profoundly affected by sediment depletion of oxygen and recycling of nutrients—processes sustained by long‐term accumulation of sediment organic matter. While sediment‐water interactions are widely recognized, quantitative understanding of sediment legacy effects remains limited. To address this gap, we developed a two‐layer

Variations of PM10 and its relationship with 7Be and 210Pb measurements at Malaga (Southeastern coast of Spain) [PDF]
INTRODUCTION Levels of particulate matter fraction PM10 were monitored between 2009 and 2011 in Malaga (Spain) in one of the Atmospheric Pollution Monitoring network managed by the Environmental Health Service of the Andalusian Government.

Spatial Variability in Deep SOC Storage in Georgia (USA) Salt Marshes
Abstract Coastal Georgia's (USA) salt marshes function as soil organic carbon (SOC) sinks because of their high primary productivity and slow decomposition rates. Quantifying SOC stocks is essential to establish a baseline for long‐term SOC trends and to highlight their capacity for long‐term carbon (C) sequestration.
