Zooplankton from the inshore waters of Christmas Island (Indian Ocean) with reference to larvae of the red land crab, Gecarcoidea natalis [PDF]

, 2010
The red land crab, Gecarcoidea natalis, which is endemic to Christmas Island in the Indian Ocean, has an obligate marine larval phase. Surface plankton tows, using a 500 um mesh net, were completed monthly at three sites on the north coast of Christmas ...

Crustal fault reactivation facilitating lithospheric folding/buckling in the central Indian Ocean

, 1996
High-quality, normal-incidence seismic reflection data confirm that tectonic deformation in the central Indian Ocean occurs at two spatial scales: whole lithosphere folding with wavelengths varying between 100 and 300 km, and compressional reactivation ...

The influence of mid-ocean ridges on euphausiid and pelagic ecology [PDF]

, 2009
Chapters 1 & 2. Euphausiids comprise a major component of ecosystems in the pelagic realm, the world’s largest habitat, but basin scale drivers of euphausiids diversity and abundance are poorly understood. Mid-Ocean Ridges are the largest topographical

Late Pleistocene Volcanic Rocks From Tengchong Volcanic Field at SE Tibetan Plateau: Constraints on Petrogenesis and Mantle and Crustal Processes

Geological Journal, EarlyView.
Early zircon saturation and crystallisation occur in mafic (52–54 wt.% SiO2) lavas at Tengchong volcanic field. These early formed zircons with high δ18O (6.6‰–7.9‰) indicates mantle enrichment by subducted supracrustal materials. ABSTRACT Late Pleistocene (< 0.2 Ma) mafic and evolved volcanic rocks occur in northern Tengchong Volcanic Field, SE ...

The Effect of Indian Ocean Surface Freshwater Flux Biases On the Multi-Stable Regime of the AMOC

Tellus: Series A, Dynamic Meteorology and Oceanography
It is known that global climate models (GCMs) have substantial biases in the surface freshwater flux. Using numerical bifurcation analyses on a global ocean model, we study here the effect of freshwater flux biases over the Indian Ocean on the multiple ...

Indian Ocean warming as key driver of long-term positive trend of Arctic Oscillation

npj Climate and Atmospheric Science, 2022
Arctic oscillation (AO), which is the most dominant atmospheric variability in the Northern Hemisphere (NH) during the boreal winter, significantly affects the weather and climate at mid-to-high latitudes in the NH.

Mineral dust sources in the surroundings of the north Indian Ocean [PDF]

Geophysical Research Letters, 2003
We have used one year (1999) of Meteosat observations to monitor the dust activity in the arid and semi‐arid areas surrounding the North Indian Ocean. The method is based on the IDDI product derived from the infrared channel of the satellite. Dust sources are located according to a threshold on the IDDI and another on the surface wind speed. The global

Apatite in Carbonatite Preserving Primary Magmatic, Post‐Magmatic Overgrowth, and Post India‐Asia Collision‐Related Hydrothermal Alteration: Evidenced From U–Pb Isotope and Trace Element Geochemistry

Geological Journal, EarlyView.
U–Pb isotope and trace element geochemistry of apatite from carbonatites of Peshawar Plain Alkaline Igneous Province, western Himalaya shows Permo‐Carboniferous magmatism, an additional magmatic pulse during Cretaceous, and post‐magmatic hydrothermal/metasomatism during Oligocene. ABSTRACT U–Pb isotope and trace element geochemistry of apatite combined
