Late Pleistocene to Holocene sedimentation in the Great Blue Hole (Lighthouse Reef, Belize): Results from a 30 m long core

The Depositional Record
The Great Blue Hole is a prominent flooded karst sinkhole, located in the lagoon of Lighthouse Reef atoll off the coast of Belize. Short cores recovered from varved bottom sediments have been used in previous studies as climate and cyclone archives ...

Clumped Isotope Temperature Reconstruction Using Stalagmite Drip Cups. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Application of clumped isotope palaeothermometry to speleothems (carbonate cave deposits, e.g., stalagmites and flowstones) has been restricted largely to subaqueous samples because of kinetic fractionation processes that occur during subaerial speleothem formation, which lead to erroneously high inferred temperatures.

ANATOMY OF A CENOTE WITH USE OF DRON

Tropical and Subtropical Agroecosystems, 2021
Background: Detailed geomorphological analysis of the karst depressions in Yucatán has received little attention because the measurement of morphometric parameters taken in the field involves a lot of work, time and costs.

Bubble trail and folia in cenote Zapote, Mexico: petrographic evidence for abiotic precipitation driven by CO2 degassing below the water table

International Journal of Speleology, 2020
Folia are speleothems that resemble bells, inverted cups, or bracket fungi, and whose origins are still controversial. Cenote Zapote (an underwater cave) in the Yucatán Peninsula (México), is home to some of the largest folia reported to date.

Transmission of Anellovirus From Kidney-Donor to Pediatric Recipient: An Exploratory Study. [PDF]

Pediatr Transplant
Donor‐to‐recipient anellovirus transmission occurred in 1 of 6 pediatric kidney transplant pairs, in a recipient with pre‐existing immunosuppression. The donor‐derived lineage became detectable 1 year after transplantation, indicating no meaningful contribution to early post‐transplant recipient TTV load and supporting continued research into TTV as an
