La Niña events often result in a strengthened LC, high coastal sea levels and unusually warm sea surface temperatures (SSTs), termed Ningaloo Niño. The rarity of such extreme events and the response of the southeastern Indian Ocean to regional and remote climate forcing are poorly understood owing to the lack of long-term records. Here we use well-replicated coral SST records from within the path of the LC, together with a reconstruction of the El Niño-Southern Oscillation to hindcast historical SST and LC strength from 1795 to 2010. We show that interannual and decadal variations in SST and LC strength characterized the past 215 years and that the most extreme sea level and SST anomalies occurred post 1980. These recent events were unprecedented in severity and are likely aided by accelerated global ocean warming and sea-level rise. #-------------------- # Authors: Kuhnert, H., J. Pätzold, B.

A 200-year proxy record of sea surface temperatures from the Houtman Abrolhos Islands off west Australia was obtained from coral δ18O. At 29′S, the Houtman Abrolhos are the southernmost major reef complex of the Indian Ocean. They are located on the path of the Leeuwin Current, a southward flow of warm, tropical water, which is coupled to Indonesian throughflow. Coral δ18O primarily reflects local oceanographic and climatic variability, which is largely determined by spatial variability of the Leeuwin Current. However, coherence between coral δ18O and the current strength itself is relatively weak. Evolutionary spectral and singular spectrum analyses of coral δ18O demonstrate a high variability in spectral composition through time. Oscillations in the 5–7-y, 14–15-y, and quasi-biennial bands reflect teleconnections of local sea surface temperature (SST) to tropical Pacific climate variability. Deviations between local (coral-based) and regional (instrument) SST contain a cyclic component with a period of 15 y. Coral δ18O suggests a rise in SST by 0.6 ′C since AD 1944, consistent with available instrumental SST records. A long-term warming by 1.4 ′C since AD 1795 is inferred from the coral record. #-------------------- # Funding_Agency # Funding_Agency_Name: Australian Research Council (ARC) # Grant: ARC DP0986505 #-------------------- # Funding_Agency # Funding_Agency_Name: Commonwealth Scientific and Industrial Research Organization (CSIRO) # Grant: Wealth from Oceans Flagship #-------------------- # Funding_Agency # Funding_Agency_Name: Australian Climate Change Science Program # Grant: #-------------------- # Site_Information # Site_Name: Houtman Abrolhos Islands (HAB05B, HAB10A, 1994) # Location: Australia # Northernmost_Latitude: -28.461 # Southernmost_Latitude: -28.465 # Easternmost_Longitude: 113.77 # Westernmost_Longitude: 113.75 # Elevation_m: #-------------------- # Data_Collection # Collection_Name: HAI Composite Z14 # First_Year: 1795 # Last_Year: 2010 # Time_Unit: CE # Core_Length_m: # Parameter_Keywords: trace metals, oxygen isotopes, physical properties # Notes: From Zinke et al.(2014): a 215-year record of reconstructed mean annual SST is derived from coral δ18O and/or Sr/Ca variations in three cores from the HAIs (Figs 1a, 2a–c; Supplementary Figs 2–5; Supplementary Tables 1 and 2). In brief, we first, normalized (subtract mean and divide by s.d.) each individual coral record to its variance using the time period 1900–1993 shared by all cores; second, aligned the new annually resolved Sr/Ca and δ18O records with the Kuhnert et al.12 annual time series, and third, averaged all records to form a composite chronology that extends from 1795 to 2010. We converted our normalized coral composite proxy record to SST by scaling it to the s.d. of extended reconstructed SST (ERSST)v3b17 (over the period 1900–1993), the longest continuous SST data set for the HAI region. #-------------------- # Chronology_Information # Chronology: #-------------------- # Variables # PaST_Thesaurus_Download_Resource:
