Incredible under what extremely harsh environments #mangroves can live and have adapted to: high #salt concentrations, #anoxia and #tidal stress. Salt crystals are visible on the leaves. Observed in #LasPenitas, #Nicaragua.

We're not "repeating the mistake", we're doing *way* worse.

Death is a disintegration of the old in favor of the true. Who are we, what are we, where are we, why are we, and how are we in this lifetime? We can ask the same of our ancestors and ancients, just as our children and descendants will ask the same of us.

Controls on the Termination of Cretaceous Oceanic Anoxic Event 2 in the Tarfaya Basin, Morocco | Published in American Journal of Science

By Chiara Krewer, Simon W. Poulton & 4 more. The recovery from OAE2 in the Tarfaya Basin was driven by decreasing chemical weathering, less intensely reducing conditions and pulses of phosphorous drawdown.

Researchers use genetic engineering to create flood-tolerant plants

Adding too much water to your plants can damage them as much as not having enough water. In the environment, plants submerged under excessive rain have limited access to light and oxygen, which reduces or eliminates their ability to thrive. This poses an important problem for crops.

First paper out of Nina Wichern's PhD (w/ other good people, also me) explores how weathering, #anoxia, and orbital forcing interacted during the Kellwasser Crisis of the Late Devonian #extinction (ca. 372 Ma).

Astronomically paced climate and carbon cycle feedbacks in the lead-up to the Late Devonian Kellwasser Crisis

Abstract. Repeated carbon isotope excursions and widespread organic-rich shale deposition mark the Middle and Upper Devonian series. Various explanations such as extensive volcanism and land plant evolution have been given for these perturbations and the general sensitivity of the Devonian oceans to the development of anoxia, but their repeated nature suggests that astronomical forcing may have controlled their timing. Here, a cyclostratigraphic study of the Kellwasser Crisis at the Frasnian–Famennian stage boundary (ca. 372 Ma) is carried out. The Kellwasser Crisis was one of the most ecologically impactful of the Devonian perturbations and is ranked among the “Big Five” Phanerozoic mass extinctions. The studied site is the Winsenberg roadcut section in the Rhenish Massif, Germany, which represents a quiet tropical shelf basin setting. Centimetre-scale elemental records, generated by portable X-ray scanning, allow for testing of the hypothesis that a 2.4 Myr eccentricity node preceded the Upper Kellwasser event. The study's results are supportive of this hypothesis. We find enhanced chemical weathering (K2O / Al2O3) during the period leading up to the Upper Kellwasser and a peak in distal detrital input (SiO2 / CaO) and riverine runoff (TiO2 / Al2O3) just prior to the start of the Upper Kellwasser event. We interpret this pattern as the long-term eccentricity minimum facilitating excessive regolith build-up in the absence of strong seasonal contrasts. The Earth's system coming out of this node would have rapidly intensified the hydrological cycle, causing these nutrient-rich regoliths to be eroded and washed away to the oceans, where they resulted in eutrophication and anoxia. An astronomical control on regional climate is observed beyond this single crisis. Wet–dry cycles were paced by 405 kyr eccentricity, with both the Lower and Upper Kellwasser events taking place during comparatively drier times. A precession-sensitive monsoonal climate system prevailed on shorter timescales. Intensification of this monsoonal system following the node may have caused the widespread regolith erosion. We estimate the total duration of the Kellwasser Crisis at ca. 900 kyr, with the individual events lasting for ca. 250 and 100 kyr, respectively. If astronomical control indeed operated via regolith development in monsoonal climates, then land plants may have played an important role. This would not have been through evolutionary steps directly triggering Kellwasser perturbations but by gradually strengthening the climatic response to orbital forcing via soil development – creating soils thick enough to meaningfully respond to orbital forcing – and intensifying the hydrological cycle.

Marine #anoxia is characterized by the oceans being severely depleted in dissolved #oxygen, making them toxic and thus having devastating impacts on the organisms inhabiting them.

Global warming caused widespread #ocean anoxia 93 million years ago.

Persistent low-oxygen layers increase in number and size with enhanced warming of the oceans, forming a thick zone at depth below a highly productive thin surface layer that is oxygen-rich.

Global warming caused widespread ocean anoxia 93 million years ago, deep-sea sediments research suggests

Marine anoxia is characterized by the oceans being severely depleted in dissolved oxygen, making them toxic and thus having devastating impacts on the organisms inhabiting them. One such event, known as Oceanic Anoxic Event 2 (OAE2), occurred ~93.5 million years ago across the Cenomanian-Turonian boundary of the Upper Cretaceous and lasted for up to 700,000 years.
