  • 23.03.2018: Seaweeds protect calcifying marine species from ocean acidification

    Ocean acidification is making it harder for calcifying marine species to construct their protective outer layers or shells. But new research suggests some organisms have found protection from lower pH levels among seaweed. As ocean water soaks up excess CO2 in the atmosphere, pH levels drop. Seaweed absorbs CO2 during the day, however, reducing the […]

  • 23.03.2018: Seaweeds shelter calcifying marine life from acidifying oceans

    Seaweeds create a chemical microenvironment at their surface, providing refuge for calcifying organisms that are at risk from decreasing oceanic pH, shows new research published in the journal Functional Ecology. CO2 in the atmosphere dissolves directly into seawater, lowering the pH and making it increasingly acidic. Kelp and other seaweeds are ecosystem engineers that shape their […]

  • 23.03.2018: Abiotic and biotic interactions in the diffusive boundary layer of kelp blades create a potential refuge from ocean acidification

    Seaweeds are able to modify the chemical environment at their surface, in a micro‐zone called the diffusive boundary layer (DBL), via their metabolic processes controlled by light intensity. Depending on the thickness of the DBL, sessile invertebrates such as calcifying bryozoans or tube‐forming polychaetes living on the surface of the blades can be affected by […]

  • 23.03.2018: Carbon–climate feedbacks accelerate ocean acidification (update)

    Carbon–climate feedbacks have the potential to significantly impact the future climate by altering atmospheric CO2 concentrations (Zaehle et al. 2010). By modifying the future atmospheric CO2 concentrations, the carbon–climate feedbacks will also influence the future ocean acidification trajectory. Here, we use the CO2 emissions scenarios from four representative concentration pathways (RCPs) with an Earth system model […]

  • 23.03.2018: Partnering with indigenous communities to anticipate and adapt to ocean change

        The productive ocean off Washington state’s Olympic Coast supports an abundant web of life including kelp forests, fish, shellfish, seabirds and marine mammals. The harvest and use of these treaty-protected marine resources have been central to the local tribes’ livelihoods, food security and cultural practices for thousands of years. But ocean acidification is […]

  • 22.03.2018: Lithium isotopic composition of benthic foraminifera: a new proxy for paleo-pH reconstruction

    The lithium isotopic composition of foraminifera is an established tracer of long-term changes in the global silicate weathering cycle, following the assumption that foraminifera faithfully record the lithium isotopic composition (δ7Li) of seawater. In this study, we demonstrate by utilizing benthic foraminifera (Amphistegina lessonii) that were cultured under decoupled pH-[CO32-] conditions, that foraminifera δ7Li is […]
