CARMA - CARbonate skeletons as cliMAtic proxy archives
CARMA: Carbonate skeletons as climatic-proxy archives. Assessment of climate
change impact on the structure, mineral and geochemical composition of calcifying
benthic fauna in the Arctic region over the last several year
PROJECT GOALS
Characteristic of the carbonate skeletons geochemistryCharacteristic of the carbonate skeletons geochemistry
Determination of the geochemical composition (i.e., Ca, Mg, Na, Sr, Mn, Ba, Cu, Pb, Y, V, Cd) of Arctic invertebrate skeletons including bryozoans, serpulidae polychaetes, and barnacles along with analysis of element concentration variability within species, among the studied taxonomic groups, and assessment of potential environmental relationships.
Analysis of Spatial Variability in Skeleton Geochemistry
Assessment of how environmental parameters including temperature, Salinity, pH, calcium carbonate saturation state (Ω), and metal concentrations in seawater (Na, Mg, Sr, Ca) in different parts of the fjord and at varying depths influence the chemical composition of calcareous organism skeletons. This will allow determination of the extent to which skeleton chemistry is controlled by the environment, whether responses to changing environmental parameters are shared across species or are species-specific, and help identify potential indicator organisms.
Assessment of long-term (2009–2027) variability in skeletal geochemical composition
Identification of interannual variability in the concentrations of individual elements in calcareous organisms will allow assessment of the impact of ongoing climate change in the Arctic on their composition and condition.
