Dear Coral-List members,

Henry Wu, Delphine Dissard, Nathalie Goodkin and Jens Zinke invite you to
submit an abstract for oral and poster presentations at ICRS 2020 to Theme
1, session "*What do corals and marine calcifiers tell us about
anthropogenic effects on ocean chemistry and global change?".*

Abstract Deadline: 1 September 2019

Session Description:

Our understanding of current and future anthropogenic impacts (e.g. thermal
stress and ocean acidification) on corals and coral reef ecosystems is
severely limited due to the lack of reliable long-term monitoring and
limited geographical coverage. Skeletal records from living and fossil, and
tropical or subtropical biogenic carbonates such as surface and deep-sea
corals, sclerosponges, bivalves, and foraminifera are key archives of
environmental variability over historical time-scales. These records not
only extend short instrumental records that started during the industrial
era, but also allow for environmental reconstructions at unconstrained
locations. Stable isotopes (e.g. δ11B, δ13C, δ15N) and trace elements (e.g.
B/Ca, Sr/Ca, Li/Mg, etc.) incorporated into skeletons of calcifying
organisms provide an indirect tool to reconstruct variations in seawater
and calcification pH, 13C Suess Effect, DIC and carbonate chemistry,
thermal stress, sediment and riverine discharge or nutrient loading, light
intensity, water mass dynamics, and coral performance in extreme
environments. This session aims to present reconstructions that identify
the most prevalent stressors on corals and coral reef ecosystems and assess
the interaction of multiple stressors on their resilience through time. In
particular, we welcome regional to global scale contributions that
characterize and precisely quantify recent or historical trends of OA,
coral responses to past bleaching events, biologically mediated
calcification mechanisms and/or "vital effects", and their sensitivities to
environmental changes. Contributors may include coral biologists and
physiologists who have concerns about the fidelity and limits of proxies
(e.g. calibration, analytical issues, application) or analyzing past
bleaching or stress events using geochemical techniques. Ecological
modelers working to increase our understanding of the impacts of OA on the
calcification of corals and reef community are also encouraged.
