“Flames Over Persepolis”: New Scientific Evidence Supporting Historical Perspectives

open access: yesArchaeometry, Volume 68, Issue 3, Page 421-433, June 2026.
ABSTRACT This study investigates the burning of Persepolis Terrace, historically attributed to Alexander III in 330 bce. A review of classical accounts and excavation reports, combined with diagnostic surveys, confirms the fire's historicity and provides novel insights.

Into the Wild: Farm‐Derived Energy and Nutrients Enter Marine Food Webs With Carrying Capacity Implications for Aquaculture Management

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Marine aquaculture is expanding globally, yet its interactions with surrounding ecosystems remain complex and insufficiently understood. This study reviews the fluxes of energy and nutrients from three major aquaculture systems: finfish cages, suspended bivalves, and seaweed farms and considers their implications for ecosystem functioning and ...

Updated calibration of the clumped isotope thermometer in planktonic and benthic foraminifera

open access: yesGeochimica et Cosmochimica Acta, 2018
Accurate reconstruction of past ocean temperatures is of critical importance to paleoclimatology. Carbonate clumped isotope thermometry (“Δ47”) is a relatively recent technique based on the strong relationship between calcification temperature and the ...

Bioerosion Drill Holes Increase Carbonate Dissolution in the Planktonic Foraminifer Globigerinoides ruber

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Planktonic foraminifera are instrumental in reconstructing paleoceanographic and paleoclimatic conditions. However, preferential dissolution can significantly bias both assemblages and chemical analyses, leading to biased interpretations. Bioerosional drill holes are commonly found in foraminiferal tests; however, it remains unknown if these ...

Three hundred eighty thousand year long stable isotope and faunal records from the Red Sea : influence of global sea level change on hydrography [PDF]

open access: yes, 1996
Stable isotope and faunal records from the central Red Sea show high-amplitude oscillations for the past 380,000 years. Positive δ18O anomalies indicate periods of significant salt buildup during periods of lowered sea level when water mass exchange with

Spatial and Temporal Variability of Eastern Pacific Radiocarbon and Carbon Chemistry From the Ice Age to Today

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 5, May 2026.
Abstract Proxy records of seawater radiocarbon (14C/C) provide strong constraints on how changes in ocean ventilation contributed to the increase in atmospheric CO2 during the termination of the last ice age (≈18,000‐to‐12,000 years ago). One outstanding problem, however, is the existence of anomalously low deglacial benthic foraminiferal 14C/C in the ...
