Decadal cyclicity of regional mid‐Holocene precipitation: Evidence from Dominican coral proxies

  title={Decadal cyclicity of regional mid‐Holocene precipitation: Evidence from Dominican coral proxies},
  author={Lisa Greer and Peter K. Swart},
[1] The stable carbon (δ13C) and oxygen (δ18O) isotopic compositions of four Holocene specimens of Montastraea sp. and Siderastrea sp. coral skeletons from the Dominican Republic were analyzed to examine decadal-scale fluctuations in regional precipitation. The specimens range in length from 47 to 197 years individually and range in age from ∼7.2 to 5.2 kyr. Oscillations in the δ13C and δ18O of coral skeletons from the Holocene Enriquillo Valley occur with a seemingly consistent frequency of 15…

Controls of Caribbean surface hydrology during the mid- to late Holocene: insights from monthly resolved coral records
Abstract. Several proxy-based and modeling studies have investigated long-term changes in Caribbean climate during the Holocene, however, very little is known on its variability on short timescales.
High-resolution windows into Holocene climate using proxy data from Belize corals (Central America)
Eleven fossil (Holocene) Montastraea coral samples from Belize barrier and atoll reef cores were analyzed geochemically. δ18O in fossil Montastraea cores suggest warmer and/or wetter conditions in
Mid-Holocene sea surface conditions and riverine influence on the inshore Great Barrier Reef
We present measurements of Sr/Ca, δ18O, and spectral luminescence ratios (G/B) from a mid-Holocene Porites sp. microatoll recovered from the nearshore Great Barrier Reef (GBR). These records were
Holocene sea surface conditions and riverine influence on the inshore Great Barrier Reef
We present measurements of Sr/Ca, δ18O, and spectral luminescence ratios (G/B) from a mid-Holocene Porites sp. microatoll recovered from the nearshore Great Barrier Reef (GBR). These records were
Mid- to late Holocene changes in tropical Atlantic temperature seasonality and interannual to multidecadal variability documented in southern Caribbean corals
Proxy reconstructions of tropical Atlantic sea surface temperature (SST) that extend beyond the period of instrumental observations have primarily focused on centennial to millennial variability
Geochemical signatures in the coral Montastraea: Modern and mid-Holocene perspectives
In the first phase of this project, four decades of monthly resolved geochemical variations from two massive heads of Montastraea were used to explore the reproducibility of the geochemical signal in
A reconstruction of sea surface temperature variability in the southeastern Gulf of Mexico from 1734 to 2008 C.E. using cross-dated Sr/Ca records from the coral Siderastrea siderea
This study uses skeletal variations in coral Sr/Ca from three Siderastrea siderea coral colonies within the Dry Tortugas National Park in the southeastern Gulf of Mexico (24°42′N, 82°48′W) to
Decadal-scale rainfall variability in Ethiopia recorded in an annually laminated, Holocene-age, stalagmite
An annually laminated, uranium-series dated, Holocene stalagmite from southeast Ethiopia has been analysed for growth rate and δ13C and δ18O variations at annual to biennial resolution, in order to
ABSTRACT During the early Holocene, rising waters of the Caribbean Sea flooded the Enriquillo Valley of southwestern Dominican Republic. A fringing coral reef developed and flourished along the
Linking hurricane landfalls, precipitation variability, fires, and vegetation response over the past millennium from analysis of coastal lagoon sediments, southwestern Dominican Republic
We reconstructed the late-Holocene environmental history of a coastal lagoon in semi-arid southwestern Hispaniola through multiproxy analysis of a sediment core, including pollen, macroscopic and

El Niño Southern Oscillation (ENSO) and decadal‐scale climate variability at 10°N in the eastern Pacific from 1893 to 1994: A coral‐based reconstruction from Clipperton Atoll
We have developed a 101 year (1893–1994) subseasonal oxygen (δ18O) and carbon (δ13C) isotopic time series from Clipperton Atoll in the eastern Pacific using the coral Porites lobata. In agreement
Stable isotope and growth records in corals from the island of Tobago : Not simply a record of the Orinoco
The geochemical composition of skeletons from corals growing around the island of Tobago is impacted by several environmental forcing factors. This project studied the stable oxygen and carbon
