Cross–Shelf Exchange Along the Antarctic Continental Margin: Modeling Results
The shelf areas around the Antarctic Continent are locations of dense water formation; part of these water masses ventilate the adjacent deep ocean basins and enter the global thermohaline circulation. This paper takes a look at regional differences of shelf sea–deep ocean exchange in high southern latitudes (mainly between the Weddell and Ross Seas), highlights a few physical mechanisms potent...
متن کاملSignificance of the Trace Fossil Zoophycos in Pliocene Deposits, Antarctic Continental Margin (ANDRILL 1B Drill Core)
Zoophycos is a complex three dimensional trace fossil that is abundant in deep ocean sediments worldwide, but has not been described previously from Cenozoic continental margin deposits of Antarctica. In the ANDRILL 1B core drilled through the northwest McMurdo ice shelf, Zoophycos occurs in a 17m thick unit of interglacial sediments bounded above and below by glacial surfaces of erosion. This ...
متن کاملHolocene variability in the intensity of wind-gap upwelling in the tropical eastern Pacific
Wind-driven upwelling in Pacific Panamá is a significant source of oceanographic variability in the tropical eastern Pacific. This upwelling system provides a critical teleconnection between the Atlantic and tropical Pacific that may impact climate variability on a global scale. Despite its importance to oceanographic circulation, ecology, and climate, little is known about the long-term stabil...
متن کاملAbrupt mid-Holocene onset of centennial-scale climate variability on the Peru-Chile Margin
[1] Understanding the natural climate variations in the eastern tropical Pacific (ETP) is crucial for predicting the evolution of the El Niño-Southern Oscillation (ENSO). Here we present the first continuous, decadal-resolution Holocene climate record from the Peru-Chile Margin, near the epicenter of the modern ENSO system. Geochemical proxies allow us to reconstruct sea surface temperature, ph...
متن کاملThe Holocene temperature conundrum.
A recent temperature reconstruction of global annual temperature shows Early Holocene warmth followed by a cooling trend through the Middle to Late Holocene [Marcott SA, et al., 2013, Science 339(6124):1198-1201]. This global cooling is puzzling because it is opposite from the expected and simulated global warming trend due to the retreating ice sheets and rising atmospheric greenhouse gases. O...
