Paleobotanical proxies for early Eocene climates and ecosystems in northern North America from middle to high latitudes [PDF]
Climate of the Past, 2020 Early Eocene climates were globally warm, with ice-free conditions at both poles. Early Eocene polar landmasses supported extensive forest ecosystems of a primarily temperate biota but also with abundant thermophilic elements, such as crocodilians, and ...

Use of Proxy Indicators to Interpret the Epi Curve of COVID-19 in Sri Lanka [PDF]
International Journal of Community Resilience, 2021 Sri Lanka has taken measures to avoid the introduction and spread of COVID-19 well before the country confirmed its first COVID 19 case on 27th January 2020, on top of its detailed epidemiological surveillance and infectious disease control system. Traditional indicators such as the daily case numbers have been used as an indicator to keep track of the

Use of mineral magnetic concentration data as a particle size proxy: a case study using marine, estuarine and fluvial sediments in the Carmarthen Bay area, South Wales, U.K. [PDF]
, 2007 Compositional (non-magnetic) data can correlate strongly with particle size, which deems it appropriate as a particle size proxy and, therefore, a reliable means of normalising analytical data for particle size effects.

Testing the timing of radiocarbon-dated events between proxy archives [PDF]
, 2007 For interpreting past changes on a regional or global scale, the timings of proxy-inferred events are usually aligned with data from other locations. However, too often chronological uncertainties are ignored in proxy diagrams and multisite comparisons ...

A comparison of Eocene climate model results to quantified paleoclimatic interpretations [PDF]
, 1992 The integration of climate model results and geologic information offers considerable potential for deriving greater insight into the geologic record. In this study, climate model results and quantified climatic interpretations derived from proxy data ...

Electron flux is a key determinant of uranium isotope fractionation during bacterial reduction
Communications Earth & Environment, 2023 Uranium isotopic signatures in the rock record are utilized as a proxy for past redox conditions on Earth. However, these signatures display significant variability that complicates the interpretation of specific redox conditions. Using the model uranium-

The response of ENSO flavors to mid‐Holocene climate: Implications for proxy interpretation [PDF]
Paleoceanography, 2015 AbstractThe response of El Niño–Southern Oscillation (ENSO) to mid‐Holocene boundary conditions remains an open question: paleoclimate proxies and climate model simulations do not agree in the magnitude of the reduction of ENSO variability, while recent proxy evidence from fossil corals from the central Pacific show that the reduction in mid‐Holocene ...

Joint Proxy Inversion for Robust Paleoenvironmental Reconstruction
, 2018 Traditional interpretations of paleoclimate proxies are based on the errant inversion of conditional probabilities. As a consequence, the resulting climate reconstructions fail to formally consider proxy response to alternative forcing factors, giving ...

Influence of regional precipitation patterns on stable isotopes in ice cores from the central Himalayas [PDF]
The Cryosphere, 2014 Several ice cores have been recovered from the Dasuopu (DSP) Glacier and the East Rongbuk (ER) Glacier in the central Himalayas since the 1990s. Although the distance between the DSP and the ER ice core drilling sites is only ~ 125 km, the stable ...
