Multi-channel seismic imaging of a crustal magma chamber along the East Pacific Rise
A reflection observed on multi-channel seismic profiles along and across the East Pacific Rise between 8°50′ N and 13°30′ N is interpreted to arise from the top of a crustal magma chamber locatedExpand

Seismic Structure of the Southern East Pacific Rise
Seismic data from the ultrafast-spreading (150 to 162 millimeters per year) southern East Pacific Rise show that the rise axis is underlain by a thin (less than 200 meters thick) extrusive volcanicExpand

A multichannel seismic study of lithospheric flexure across the Hawaiian–Emperor seamount chain
Existing models assume that the thickened crust beneath seamounts is the result of a surface volcanic load flexing an elastic plate. New results suggest that flexed oceanic crust beneath theExpand

No evidence from multichannel reflection data for a crustal magma chamber in the MARK area on the Mid-Atlantic Ridge
THE role of crustal magma chambers in the construction of oceanic crust along the slowly spreading Mid-Atlantic Ridge (MAR) is still highly disputed1. Some investigators have argued for small,Expand

Seismic Images of Active Magma Systems Beneath the East Pacific Rise Between 17{degrees}05' and 17{degrees}35'S.
Seismic reflection data from the East Pacific Rise between 17 degrees 05' and 17 degrees 35'S image a magma lens that varies regularly in depth and width as ridge morphology changes, confirming theExpand

Platygaster robiniae n. sp. (Hymenoptera: Platygastridae) Parasitoid of Obolodiplosis robiniae (Diptera: Cecidomyiidae) in Europe
Abstract The gall midge Obolodiplosis robiniae (Haldeman) (Diptera Cecidomyiidae), originating from North America and damaging to black locust (Robinia pseudoacacia L.), was detected for the firstExpand

Magma distribution across ridge-axis discontinuities on the East Pacific Rise from multichannel seismic images
Detailed studies of the morphology of the East Pacific Rise axis have shown that its linearity is disrupted by many small but distinct non-transform offsets, including overlapping spreading centresExpand

Comparative emergence phenology of the orange wheat blossom midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae) and its parasitoids (Hymenoptera: Pteromalidae and Platygastridae) under
Abstract The orange wheat blossom midge, Sitodiplosis mosellana (Gehin) (Diptera: Cecidomyiidae), is a wheat ( Triticum aestivum L.) pest that can cause significant yield losses. SeveralExpand

A revised catalogue of the Platygastridae of the British Isles (Hymenoptera: Platygastroidea)
About 260 species of Platygastridae are listed from the British Isles. Forty-seven species and one genus are recorded as new to the UK. Fourteen new synonymies are proposed: Amblyaspis roborisExpand
