Unusual sea-floor fabric near the Bullard fracture zone imaged by GLORIA sidescan sonar
Read more of: Unusual sea-floor fabric near the Bullard fracture zone imaged by GLORIA sidescan sonarTHE tectonic fabric of the sea floor created at spreading ridges generally curves in the direction of ridge offset near transform faults, owing to the influence of shearing stress on […]

Effects of ridge crest-trench interaction on Antarctic-Phoenix Spreading: Forces on a young subducting plate
Read more of: Effects of ridge crest-trench interaction on Antarctic-Phoenix Spreading: Forces on a young subducting platePrecise measurements of spreading rates on marine magnetic profiles collected to the west of the Antarctic Peninsula have enabled some consideration of the forces governing plate motion, since Antarctic—Phoenix motion […]

Neogene interaction of tectonic and glacial processes at the Pacific margin of the Antarctic Peninsula
Read more of: Neogene interaction of tectonic and glacial processes at the Pacific margin of the Antarctic PeninsulaThe Antarctic Peninsula was a magmatic arc subducting Pacific Ocean floor throughout the Mesozoic. During the Cenozoic, subduction ceased at each of a series of ridge‐crest–trench collisions, which migrated northeast […]

Sporadic-E as a tracer for atmospheric waves
Read more of: Sporadic-E as a tracer for atmospheric wavesDuring three days of quiet geomagnetic conditions in August 1988, both the EISCAT UHF radar and the NOAA digital ionospheric sounder (Dynasonde) were operated from 12:00 to 22:00 U.T. Sporadic-E […]

Effectiveness of different shooting techniques in Antarctic firn
Read more of: Effectiveness of different shooting techniques in Antarctic firnThe British Antarctic Survey has commenced a programme of multichannel seismic reflection work over the Antarctic continental ice sheet and surrounding ice shelves. This is part of an integrated geophysical […]

NO2 overnight decay and layer height at Halley Bay, Antarctica
Read more of: NO2 overnight decay and layer height at Halley Bay, AntarcticaGround‐based measurements of stratospheric slant column NO2 amounts made at Halley Bay, Antarctica in 1987 are compared with ozone and temperature profiles from balloon‐borne sondes. Sunrise‐to‐sunset (am/pm) ratios of NO2 […]
