Magma chamber and mantle reflections – East Pacific Rise

Geophysical Research Letters, 1980
A multichannel seismic reflection profile of stacked and migrated common depth point data across the East Pacific Rise near the Siqueiros Fracture Zone supports and extends previous observations (at two crossings 27 to 50 km to the south) of reflections assumed to be from the top of a magma chamber and of reflections from the M‐discontinuity.

History of oceanic front development in the New Zealand sector of the Southern Ocean during the Cenozoic--a synthesis [PDF]

, 2001
The New Zealand sector of the Southern Ocean (NZSSO) has opened about the Indian-Pacific spreading ridge throughout the Cenozoic. Today the NZSSO is characterised by broad zonal belts of antarctic (cold), subantarctic (cool), and subtropical (warm ...

A Geomorphometric Approach to Estimate the Deterioration of Earthen Archaeological Sites by Rainfall and Diffusion Processes: The Huaca Chornancap (Eighth–14th Century ad), Lambayeque, Peru

Archaeological Prospection, EarlyView.
ABSTRACT Rain‐induced erosion processes can severely damage Earthen archaeological sites. Huaca Chornancap (HCH; eighth–14th century ad) is a platform located in the Lambayeque region (Peru) exposed to seasonal rain due to El Niño Southern Oscillation (ENSO).

CCD digital camera maps the East Pacific Rise

Eos, Transactions American Geophysical Union, 1992
Since the pioneering work of Ewing et al. [1946] and Edgerton [1963] on the development of modern deep‐sea camera systems, photographs of the deep seabed have been fundamental to marine geological investigations, portraying deep‐sea fauna and permitting study of seafloor morphology at scales ranging from centimeters to meters [e.g., Heezen and ...

“Hands‐On” white matter anatomy: Using Air Anatomy gestures and tractography on simple brain sections to enhance teaching of white matter directions

Anatomical Sciences Education, EarlyView.
Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.

Lava Geochemistry as a Probe into Crustal Formation at the East Pacific Rise [PDF]

Oceanography, 2012
Basalt lavas comprise the greatest volume of volcanic rocks on Earth, and most of them erupt along the world's mid-ocean ridges (MORs). These MOR basalts (MORBs) are generally thought to be relatively homogeneous in composition over large segments of the

Revised Pacific-Antarctic plate motions and geophysics of the Menard Fracture Zone [PDF]

, 2008
A reconnaissance survey of multibeam bathymetry and magnetic anomaly data of the Menard Fracture Zone allows for significant refinement of plate motion history of the South Pacific over the last 44 million years.

Global and regional knowledge of antibiotic use and resistance among healthcare students: A systematic review and meta‐analysis

British Journal of Clinical Pharmacology, EarlyView.
Aims We synthesized and analysed existing evidence on healthcare students' knowledge of antibiotic use and resistance to provide pooled global and regional estimates. Methods The PubMed®, Embase® and CINAHL databases were searched for studies published between January 2015 and October 2025 that reported the knowledge of antibiotic use and resistance ...

Fine structure of an oceanic crustal section near the East Pacific Rise [PDF]

, 1978
In this study we model synthetically a complete seismic profile of roughly 20-m.y.-old crust located to the west of the East Pacific Rise, 3.37S, 114.13W.
