Autor: Yassine Ait Brahim, Matthew C. Peros, André E. Viau, Mercedes Liedtke, Jesús M. Pajón, Julio Valdes, Xianglei Li, R. Lawrence Edwards, Eduard G. Reinhardt, Frank Oliva
Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-12 (2022)
Abstract We present a speleothem record from western Cuba, spanning the period 98.7–84.9 ka BP. Our record shows two distinctive periods of high δ18O corresponding to dry and/or cold periods during 85–87.6 and 90.2–93.1 ka BP, synchronous with

Abstract The collapse of the Maya civilization in the late 1st/early 2nd millennium CE has been attributed to multiple internal and external causes including overpopulation, increased warfare, and environmental deterioration. Yet the role hurricanes

Anthropogenic events captured within sediment in Hidden River Cave, Kentucky
Autor: Samantha K. Feist, John C. Maclachlan, Eduard G. Reinhardt, Hannah S. Skelding
Publikováno v: Quaternary Science Advances, Vol 1, Iss , Pp 100001- (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. Hidde

Publikováno v: Patterson, R T, Nasser, N A, Reinhardt, E G, Patterson, C W, Gregory, B R B, Mazzella, V, Roe, H M & Galloway, J M 2022, ' End-member mixing analysis (EMMA) as a tool for the detection of major storms in lake sediment records ', Paleoceanography and Paleoclimatology, vol. 37, no. 11, e2022PA004510 . https://doi.org/10.1029/2022pa004510, https://doi.org/10.1029/2022PA004510
Major Tropical Cyclone (TC) events cause extensive damage in coastal regions of the western North Atlantic Basin. The short instrumental record leaves significant gaps in understanding long-term trends in TC recurrence and intensity, creating uncerta

Water-level change recorded in Lake Pac Chen Quintana Roo, Mexico infers connection with the aquifer and response to Holocene sea-level rise and Classic Maya droughts
Autor: Marek Stastna, Aaron Coutino, Eduard G. Reinhardt, Dominique Rissolo, Sam Meacham, Anya Krywy-Janzen, Brenda Waltham, Peter J. van Hengstum, Chelsi A. McNeill-Jewer
Publikováno v: Journal of Paleolimnology. 62:373-388
Pac Chen Lake is located on the Yucatan Peninsula, Mexico and is ~ 42 km from the coast and ~ 22 km NE of Coba. It has an area of ~ 36,735 m2 and maximum depth of 25 m. Four sediment cores along a depth transect provide a 4-ka record of the evolution

Core-scanning X-ray Fluorescence (XRF-CS) is a well-established technique for rapid (30 replicate analyses for up to 180 samples in a single XRF-CS run. These replicate measurements allow for rigorous testing of precision and accuracy of XRF-CS data.

The iBox-FC: A new containment vessel for Itrax X-ray fluorescence core-scanning of freeze cores
Autor: Eduard G. Reinhardt, Jennifer M. Galloway, R. Timothy Patterson, Braden R.B. Gregory
Publikováno v: Quaternary International. 514:76-84
A combination of Itrax micro-X-ray fluorescence core scanning (μXRF-CS) and freeze coring can facilitate the development of high-resolution (e.g. sub-decadal) paleoclimate records in lacustrine systems where low sedimentation rates and poorly consol
