These metabolic processes are largely controlled by the changes of environment in which they live, so Zn isotopic compositions (d66Zn) in coral skeletons may possibly serve as potential tracers for climate and environmental changes. In this study, we first reported the d66Zn in shallow-water coral skeletons by investigating with monthly resolution d66Zn values in the skeleton of a modern Porites coral 10AR2 from the Great Barrier Reef of Australia, and the bulk skeletal d66Zn values of several coral species from the Luhuitou Reef of Hainan Island in the northern South China Sea. Correlations between d66Zn and other climate and environmental proxies (Sr/Ca, d18O, and d13C) and instrumental environmental variables (sea surface temperature, river runoff, and chlorophyll a) are poor, suggesting that the effects of external environmental changes on monthly variations in d66Zn in coral skeletons are not significant. However, significant interspecific differences in the skeletal d66Zn of corals growing under identical external environments may suggest the occurrence of biologically controlled d66Zn fractionation during coral skeletons formation. In addition, the monthly d66Zn in the 10AR2 coral skeleton roughly decreases with increasing temperature, which is in agreement with the recent finding that d66Zn in coral tissues and zooxanthellae increases with increasing temperature and can serve as a proxy for thermal stress in corals. We thus suggest that the complicated coral internal biological processes hinder the use of skeletal d66Zn as a climate and environmental proxy. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: # Grant: #--------------------------------------- # Site_Information # Site_Name: Arlington Reef # Location: Australia # Northernmost_Latitude: -16.6381 # Southernmost_Latitude: -16.6381 # Easternmost_Longitude: 146.1036 # Westernmost_Longitude: 146.1036 # Elevation_m: -4 #--------------------------------------- # Data_Collection # Collection_Name: 10AR2 isotopes, trace metals Xiao2020 # First_Year: 2006 # Last_Year: 2010 # Time_Unit: year Common Era # Core_Length_m: # Parameter_Keywords: chemistry, carbon isotopes, oxygen isotopes, trace metals # Notes: Porites sp. #--------------------------------------- # Chronology_Information # Chronology: #--------------------------------------- # Variables # PaST_Thesaurus_Download_Resource: https://www.ncei.noaa.gov/access/paleo-search/skos/past-thesaurus.rdf # PaST_Thesaurus_Download_Description: Paleoenvironmental Standard Terms (PaST) Thesaurus terms, definitions, and relationships in SKOS format. # # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-var components: what, material, error, units, seasonality, data type, detail, method, C or N for Character or Numeric data) # ## SampleName sample identification,Porites sp.,,,,corals and sclerosponges,,,C, ## Age age,,,year Common Era,,corals and sclerosponges,,,N, ## d13C delta 13C,Porites sp.,,per mil VPDB,,corals and sclerosponges,,isotope ratio mass spectrometry,N, ## d18O delta 18O,Porites sp.,,per mil VPDB,,corals and sclerosponges,,isotope ratio mass spectrometry,N, ## Sr/Ca strontium/calcium,Porites sp.,,millimole per mole,,corals and sclerosponges,,inductively-coupled plasma atomic emission spectroscopy,N, ## Zn zinc,Porites sp.,,microgram per gram,,corals and sclerosponges,,inductively-coupled plasma mass spectrometry,N, ## d66Zn delta 66Zn,Porites sp.,,per mil JMC 3–0749L,,corals and sclerosponges,,multiple collector inductively-coupled plasma mass spectrometry,N, ## d66Zn_2SD delta 66Zn,Porites sp.,two standard deviations,per mil JMC 3–0749L,,corals and sclerosponges,,multiple collector inductively-coupled plasma mass spectrometry,N, ## N number of samples,Porites sp.,,count,,corals and sclerosponges,,,N,Replicated times of the same solution. #------------------------ # Data: # Data lines follow (have no #) # Data line format -
