Cold-water corals (CWCs) are important ecosystem engineers in the deep sea that provide habitat for numerous species and can form large coral mounds. These mounds influence surrounding currents induce distinct hydrodynamic features, such as internal waves episodic downwelling events accelerate transport of organic matter towards mounds, supplying with food. To date, research on distribution at has focussed either seasonal timescales or provided single point snapshots. Data food timescale a...
Abstract Studying monsoon dynamics during past warm time periods such as the Miocene Climatic Optimum (MCO; ∼16.9–14.5 Ma) could greatly aid in better projecting intensity, context of future greenhouse warming. However, studies on regional MCO temperature change and its effect monsoons this period are lacking. Here, we present first high‐resolution, low‐latitude record sea surface (SST) paleoceanographic covering Optimum, eastern equatorial Atlantic, at Ocean Drilling Program Site 959, based...
Abstract Detailed analysis of tropical climate dynamics is lacking for the Early to Middle Miocene, even though this time interval bears important analogies future climates. Based on high‐resolution proxy reconstructions sea surface temperature, export productivity and dust supply at Ocean Drilling Program Site 959, we investigate astronomical forcing West African monsoon in eastern equatorial Atlantic across prelude, onset, continuation Miocene Climatic Optimum (MCO; 18–15 Ma). Along with...
Studying West African Monsoon (WAM) dynamics during past warm time periods such as the Miocene Climatic Optimum (MCO; ~16.9 – 14.5 Ma) could greatly aid in better projecting monsoon intensity, context of future greenhouse warming. However, studies on regional MCO temperature change and its effect WAM system this period are lacking. Here, we reconstruct a ~1.5 °C rise sea surface (SST) at onset (16.9 eastern equatorial Atlantic Ocean, Ocean Drilling Program (ODP) Site 959, based TEX86...
Detailed analysis of tropical climate dynamics is lacking for the Early to Middle Miocene, even though this time interval bears important analogies future climates. Based on high-resolution proxy reconstructions sea (sub)surface temperature, export productivity and dust supply at Ocean Drilling Program Site 959, we investigate orbital forcing West African monsoon in eastern equatorial Atlantic across prelude, onset, continuation Miocene Climatic Optimum (MCO; 18-15 Ma). Along with previously...
Some fifteen years ago, the pioneering Arctic IODP Expedition 302 (ACEX) drilled, and partly recovered Cenozoic sedimentary successions at Lomonosov Ridge (LR) close to North Pole. Of few intervals recovered, one was regarded likely encompass Paleogene-Neogene (P/N) transition. On board follow up marine palynological (mainly dinoflagellate cyst) studies indicate that within this P/N section, a hiatus lasting ~ 25 Myr separates top of Paleogene (dated ~44 Ma, mid Eocene) from locally base...
The Miocene Climatic Optimum (MCO, ~17-15 Ma) was a relatively warm interval that interrupted the Cenozoic cooling trend and bears analogies with projected end-of-the-century climate. Proxy data model simulations indicate temperatures were on average ~7 – 8°C higher than present day atmospheric pCO2 values 500-600 ppmV. At high latitudes, upper ocean ~10 15°C warmer day, but available tropical temperature records are limited. Importantly, to be able use...
<p>Some fifteen years ago the pioneering Arctic IODP Expedition 302 (ACEX) partly recovered Cenozoic sedimentary successions at Lomonosov Ridge (LR) close to North Pole. Among few more completely cored intervals one was regarded likely encompass Paleogene-Neogene (P/N) transition. In effect, on board and follow up marine palynological studies indicated that P/N transition is here marked by a major hiatus spanning some 25 Myr (from ~44 Ma, mid Eocene, ~18 early Miocene)....
