Oceanic anoxia and extinction in the latest Ordovician

Mu Liu et al.

Summary: This study explores the relationship between the Late Ordovician mass extinction and global marine anoxia through uranium isotope analysis. The research reveals that two episodes of widespread marine anoxia occurred during the Late Katian and the mid-late Hirnantian, with varying effects on biotic turnover.

Phosphorus Cycle and Primary Productivity Changes in the Tethys Ocean During the Permian-Triassic Transition: Starving Marine Ecosystems

Johann Muller et al.

Summary: The ultimate cause of the end-Permian mass extinction is still debated, but global warming caused by greenhouse gas emissions is widely accepted as an initial trigger. A decline in primary productivity within the Tethyan realm prior to the extinction event may explain the perturbations among marine heterotrophic organisms.

Geochemical Records Reveal Protracted and Differential Marine Redox Change Associated With Late Ordovician Climate and Mass Extinctions

Nevin P. Kozik et al.

Summary: This study analyzes iodine and sulfur isotope geochemical data from three globally distributed carbonate successions to constrain changes in local and global marine redox conditions during the Late Ordovician. The results suggest that locally anoxic conditions were pervasive on shallow carbonate shelves, while global euxinic conditions decreased. This research provides important constraints on local and global marine redox conditions during the Late Ordovician.

Development of carbonate-associated phosphate (CAP) as a proxy for reconstructing ancient ocean phosphate levels

Matthew S. Dodd et al.

Summary: Phosphorus is crucial in oceanic ecosystems over geological timescales, affecting global carbon cycling and redox conditions. Experimental studies have shown that CAP can be used as a tool for reconstructing ancient oceanic phosphate concentrations, providing valuable insights into the ocean's nutrient history.

Vertical decoupling in Late Ordovician anoxia due to reorganization of ocean circulation

Alexandre Pohl et al.

Summary: The study found evidence of seafloor anoxia during the late Ordovician glacial period, but also showed increased upper-ocean oxygenation. Through simulation studies, it was revealed that reorganization of ocean circulation during the late Ordovician altered oxygen levels in the water column, challenging previous assumptions about the relationship between climate states and oxygen levels.

Climate changes in the pre-Hirnantian Late Ordovician based on δ18Ophos studies from Estonia

Peep Mannik et al.

Summary: Conodont-based delta O-18(phos) studies from two core sections in Estonia indicate a general cooling trend in the pre-Hirnantian Late Ordovician, with variable temperature changes and multiple cooling events. Results do not show a straightforward correlation between temperature trends inferred from delta O-18(phos) measurements and changes in the delta C-13 record.

Middle Ordovician astrochronology decouples asteroid breakup from glacially-induced biotic radiations

Jan Audun Rasmussen et al.

Summary: Evidence from 469-million-year-old Palaeozoic era suggests a link between orbital changes and climatic- and biotic variations, indicating a universal orbital control in modulating climate and biodiversity accumulation through geological time. The study decouples millennia-scale climate and biodiversity change from a meteorite shower that occurred 468.4 million years ago.

The Mid-Ludfordian (late Silurian) Glaciation: A link with global changes in ocean chemistry and ecosystem overturns

Jiri Fryda et al.

Summary: This study reviews the significant perturbations in the Phanerozoic carbon cycle, particularly focusing on the Mid-Ludfordian Carbon Isotope Excursion (MLCIE) and its associated climate changes, marine temperature variations, and geological events. The research findings provide evidence for global cooling during the MLCIE, along with occurrences of climate cooling events, oceanic anoxic events, and extinctions, highlighting the complex interactions between carbon cycling, climatic shifts, and ecosystem disruptions during this period in the late Silurian.

Redox conditions and nitrogen cycling in the Late Ordovician Yangtze Sea (South China)

Min Li et al.

Summary: The study revealed a significant shift in nitrogen isotopes from the Wufeng Formation to the Longmaxi Formation in the Yangtze Sea region, indicating changes in oceanic redox conditions. This suggests that the nitrogen cycle perturbation during the pre- and post-Hirnantian intervals was directly related to environmental changes, with anaerobic processes dominating the nitrogen cycle in the Wufeng Formation and denitrification and anaerobic processes playing a more important role in the Longmaxi Formation. Nitrogen isotopes serve as a reliable indicator of paleoenvironmental changes and are valuable for understanding paleodepositional conditions and global geological events during the Ordovician-Silurian period.

Summary: The Late Ordovician Mass Extinction happened in two phases, primarily due to marine anoxia and deteriorating climate. Globally expansive ocean anoxia was most prominent during LOME2, while periodic sulfidic anoxia developed during LOME1.

Carbon isotope chemostratigraphy and sea-level history of the Hirnantian Stage (uppermost Ordovician) in the Oslo-Asker district, Norway

Mikael Calner et al.

Summary: Based on analysis of 208 whole-rock samples from six outcrops in southern Norway, a delta C-13(carb) chemostratigraphy for the Late Ordovician Hirnantian Stage is presented. The study reveals that the HICE occurred in the latest part of the Hirnantian Age, associated with substantial shallowing of depositional environments and four glacio-eustatically controlled sea-level lowstands with increased exposure and erosion.

Volcanism-induced late Boda warming in the Late Ordovician: Evidence from the Upper Yangtze Platform, South China

Yangbo Lu et al.

Summary: The study conducted on bentonite beds-bearing intervals from the Upper Ordovician Wufeng Formation in South China reveals the short-term and long-term impacts of volcanic activity on the paleoenvironment. Short-term effects include environmental disruptions such as ocean fertilization and warmer climate, while the long-term effects show a correlation between distribution of bentonite beds and global sea-level fluctuations, suggesting a cumulative heating effect from intense volcanic activities in South China.

Summary: Brachiopods are commonly used in Palaeozoic sediments to study stable C and O isotopic compositions. By analyzing Late Ordovician and early Silurian samples, this study shows a correlation between high C and O isotope values and colder episodes, as well as a global cooling event observed in the bulk carbonate 518O values.
