IFGHH Weigel W. 266 n miles G26
Seismic refraction (no.of nautical miles)
Seismic refraction using ocean bottom hydrophones to characterize the variability of the physical parameters of the basaltic crust (laker 2a) and to study the crust/mantle boundary seismically no
IFGHH Weigel W. 2043 n miles G28
Magnetic measurements
Magnetic to map the seafloor spreading anomalies to estimate the age of crust (0-8 million years) and to study magnetic structures devoloped in conjunction with crustal revolution. Continuous recording on all seismic refraction and reflection profiles no
GEOUNB Villinger Heinrich 17 stations G71
In-situ sea floor measurements
83 geothermal measurements to measure heat flow along a transect across the flank of the superfast spreading east Pacific Rise; lister probe no
IFGHH Weigel W. 24 stations G72
Geophysical measurements made at depth (below near surface and above seafloor)
19 stat.: ocean bottom hydrophone (deployed/recovered), 5 stat.: sea bottom seismic system (deployed/recovered) no
IBGMHH Wong H.K. 2099 n miles G73
Single-beam echosounding
Parasound, sediment echo sounder; differencial frequency of 2,5-5,5 kHz; morphology of the seabottom and the structure of the uppermost sedimentary layers and for selection of heat flow stations. no
IFGHH Weigel W. 9250 km G74
Multi-beam echosounding
Hydrosweep, fan-type echosounder; frequency 15.5 kHz; mapping of the ocean bottom morphology. continuous recording on all seimic reflection, refraction and transit profiles no
IBGMHH Wong H.K. 1993 n miles G76
Multichannel seismic reflection
High resolution seismic reflection to map seismo-stratigraphically the distribution, thickness and facies of the sediments as a function of crustal age no
IFGHH Weigel W. 3 stations H10
CTD-Stations
CTD multiprobe MARK III C (at 2 stat.) and CTD-ME probe (at 1 stat.) for comparative measurements of the physical parameters of pressure, temperature and conductivity and to get the compressional wave velocity distribution in the water column for the purpose of seismic modeling and hydrosweep meas. and temp. calibration of the geothermal probe. no
