Coral rare earth element tracers of terrestrial exposure in nearshore corals of the Great Barrier Reef, in Proceedings of the 11th International Coral Reef Symposium, Fort Lauderdale, Florida. # Abstract: Rare earth element and yttrium (REY) concentrations were measured from two nearshore Porites sp. corals collected from Round Top Is. and Keswick Is., at 5 km and 32 km offshore from Mackay, Queensland, on the southern Great Barrier Reef, Australia. The REY patterns from the Round Top coral differed from the Keswick coral in 5 respects: (1) greater REY concentrations; (2) preferentially enriched light rare earth elements (LREEs); (3) reduced slope across the heavy rare earth elements (HREEs); (4) more negative cerium (Ce) anomaly; and (5) lower yttrium (Y) to holmium (Ho) ratios. These patterns suggest greater terrestrial exposure and higher biological productivity at Round Top Is. Total abundance of REY in both corals increased over time between 1950 and 2002. The rate of increase at Round Top Is. was 3-fold greater than at Keswick Is., thus the innermost site was likely more influenced by weathering from rapid agricultural expansion in the adjacent Pioneer River catchment. The Y/Ho ratio decreased over time in both corals, but as the coral values were substantially higher than ambient seawater, more research is suggested to identify the cause. #--------------------------------------- # Publication # Authors: Jupiter, S. # Published_Date_or_Year: 2006 # Published_Title: From Cane to Coral Reefs: Ecosystem Connectivity and Downstream Responses to Land Use Intensification # Journal_Name: Thesis # Volume: # Edition: # Issue: # Pages: # Report_Number: # DOI: # Online_Resource: # Full_Citation: Jupiter, S.D. 2006.

PhD Thesis, University of California, Santa Cruz, pp. 600. # Abstract: Clearing of catchments draining into the Great Barrier Reef Lagoon (Queensland, Australia) has increased sediment and nutrient loads in river runoff. The extent of land cover change and the intensification of land use were analyzed for the Pioneer River catchment near Mackay (from Landsat images, 1972-2004), and for the estuary (from aerial photographs, 1948-2002), to determine whether and how loss of natural vegetation has affected sediment delivery to nearshore waters and adjacent coral reefs. Geochemical proxy records of weathering and sediment delivery to the sea, deposited in skeletons of living Porites corals from inshore (5 km from Pioneer mouth) and midshelf (32-51 km offshore) reefs, were analyzed to determine the spatial and temporal extent of terrestrial impacts. High-temporal resolution (~weekly) concentrations of barium (Ba), yttrium (Y) and calcium (Ca) were measured by laser ablation inductively-coupled mass spectrometry (LA-ICP-MS), while annual samples of rare earth elements and yttrium (REY) were measured by solution ICP-MS. Major trends emerging from integration of contemporaneous terrestrial changes, marine geochemical proxies and climate records include: 1. A 33% net decline (1972-2004) of forests on alluvial plains as farms encroached into riparian zones; and a 22% net decline (1948-2002) of tidal mangroves in the estuary. 2. Ba/Ca correlations with Pioneer River discharge were influenced by wind direction and strength; but there was no apparent temporal change in Ba/Ca since 1946. The absence of enrichment in mean inshore Ba/Ca ratios (versus midshelf reefs) may be due to biological recycling by phytoplankton, which may restrict Ba availability. 3. Mean Y/Ca ratios from inshore (5 km) corals were 3.1 and 3.6 times higher than from midshelf (32 and 51 km) corals, and inshore REY abundances were ~2-5 times higher than from mishelf reefs. Inter-annual REY variation on both inshore and midshelf sites was correlated significantly with year and discharge, while long-term temporal trends in maximum annual Y/Ca, normalized to Pioneer River discharge, appear to reflect both agricultural expansion and changing management practices. 4. The combination of high turbidity and high nutrient discharge from the Pioneer River may be affecting benthic community composition on both inshore and midshelf reefs. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: Australian Research Council # Grant: Linkage grant LP050896 #--------------------------------------- # Site_Information # Site_Name: Round Top Island # Location: Great Barrier Reef, Australia # Northernmost_Latitude: -21.1708 # Southernmost_Latitude: -21.1708 # Easternmost_Longitude: 149.2644 # Westernmost_Longitude: 149.2644 # Elevation_m: -4 #--------------------------------------- # Data_Collection # Collection_Name: RTF trace metals Jupiter2008 # First_Year: 1950 # Last_Year: 2002 # Time_Unit: year Common Era # Core_Length_m: # Parameter_Keywords: trace metals # Notes: Porites sp.
