Through a series of field and laboratory experiments, we aimed to: 1. Study seasonal calcification rates of common Kimberley corals over two years; 2.

Three experimental sites with varying degrees of tidal influence were chosen to assess the broadest range of light and temperature variability. To compare the calcification rates of Kimberley corals with similar genera from a more typical tropical reef, a comparative study was conducted at Coral Bay in the southern part of the Ningaloo Reef Tract. Calcification rates of Acropora muricata (branching), Dipsastraea favus (massive) and Lobophyllia hemprichii (massive) from a back-reef site were measured over the same time period as for the Kimberley corals. 2) Thermal tolerance and bleaching thresholds of Kimberley corals. In April/May 2014, a controlled experiment was conducted to assess the thermal tolerance and bleaching thresholds of two common Kimberley corals at the Kimberley Marine Research Station in Cygnet Bay. Branching Acropora aspera and massive Dipsastraea sp. corals were collected from a tide pool and a subtidal environment, respectively. They were maintained in shaded outdoor flow-through miniflumes at ambient +2°C and ambient +3°C temperatures for 11 days. A daily temperature variation of 4-5°C characteristic of intertidal habitats was simulated in all treatments. Seawater temperature, salinity, carbonate chemistry, and nutrients were monitored on a regular basis. 3) Historic records from Porites cores Using massive long-lived (50 -100 years) Porites colonies, it is possible to obtain long-term records of both climate and environmental change using preserved geochemical characteristics to quantify changes in seawater temperature (Sr/Ca, Li/Mg), pH (boron isotopes), salinity(oxygen isotopes and Sr/Ca), terrestrial runoff (Ba/Ca) and other parameters. Similarly, long-term coral calcification rates can be reconstructed from a combination of the annual linear extension rate and density. In April 2016, a ~1.2m-long coral core was collected from a massive Porites spp. colony in the subtidal zone of Shell Island near Cygnet Bay, of which the skeletal growth covers the calendar years from 1919 to 2015. High-resolution and annually-resolved geochemical measurements were conducted at the Advanced Geochemical Facility for Indian Ocean Research at UWA.

Brief description

The overall objectives of this project are to understand how corals, the key ecosystem engineers on tropical reefs, have adapted and will respond in the future to the extreme variations in physical (e.g. light, temperature, water motion) and chemical (e.g. pCO2, oxygen, and nutrients) conditions characteristic of the Kimberley coastal region. Through a series of field and laboratory experiments, we aimed to: 1. Study seasonal calcification rates of common Kimberley corals over two years; 2. Assess their thermal tolerance and establish the first bleaching thresholds for this region; and 3. Reconstruct their resilience to historical climate and environmental extremes using geochemical proxies in coral cores. Data stored on Pawsey Data Store and UWA IRDS store. The raw data from the 2017 paper are also archived in the Pangaea database.
