Anthropogenic events captured within sediment in Hidden River Cave, Kentucky

open access: yesQuaternary Science Advances, 2020
Karstic cave systems are intricately related to surficial processes and the study of cave sediments is a growing field of research. Sediment deposits in caves are protected from surficial weathering processes, and are therefore often preserved.

Interannual Variations of D14CTOC and Elemental Contents in the Laminated Sediments of the Santa Barbara Basin During the Past 200 Years

open access: yesFrontiers in Marine Science, 2022
A 51-cm core (SBB-8-2012) from the depo-center of Santa Barbara Basin (SBB), California has been dated by 210Pb dating and varve counting, spanning a depositional history during 1815-2011 CE. A total of 89 AMS 14C measurements on samples from 66 horizons,

Sediment structure and physicochemical changes following tidal inundation at a large open coast managed realignment site [PDF]

open access: yes, 2018
Managed realignment (MR) schemes are being implemented to compensate for the loss of intertidal saltmarsh habitats by breaching flood defences and inundating the formerly defended coastal hinterland.

A tale of two lakes: a multi-proxy comparison of Lateglacial and Holocene environmental change in Cappadocia, Turkey [PDF]

open access: yes, 2016
Individual palaeoenvironmental records represent a combination of regional-scale (e.g. climatic) and site-specific local factors. Here we compare multiple climate proxies from two nearby maar lake records, assuming that common signals are due to regional-

A chironomid-based reconstruction of summer temperatures in NW Iceland since AD 1650 [PDF]

open access: yes, 2011
Few studies currently exist that aim to validate a proxy chironomid-temperature reconstruction with instrumental temperature measurements. We used a reconstruction from a chironomid percentage abundance data set to produce quantitative summer temperature

Does climate change alter the nutrient trends of Cedrela fissilis Vell. trees in the southern Brazilian Amazon?

open access: yesEcological Processes, 2023
Background The increase in the frequency and intensity of droughts is pointed out as one of the main factors altering biogeochemical cycles in the Amazon basin.

XRF core scanners as a quick and good screening tool for detecting pollution in sediment cores

open access: yesFrontiers in Marine Science, 2014
The capabilities of X-Ray Fluorescence (XRF) core scanners, to acquire high-resolution geochemical data sets in relatively short time, have made them an increasingly popular geochemical screening tool to study sediment cores for palaeoclimatologic and ...

Holocene environmental changes in the highlands of the southern Peruvian Andes (14° S) and their impact on pre-Columbian cultures [PDF]

open access: yesClimate of the Past, 2015
High-altitude peatlands of the Andes still remain relatively unexploited although they offer an excellent opportunity for well-dated palaeoenvironmental records.
