Note
titleAttention:

Airguns Cluster Refraction Seismic is part of the Marine Seismic Equipment.

Please note that operations with the Seismic Equipment can only be operated upon request. Request operations with the Seismic Equipoment to AWI Geophysics and AWI-Logistics in sufficient time prior to the cruise. The operations of the system require experienced scientific staff on board.

0Summary

In

the

seismic

refraction

method,

seismic

waves

are

recorded

that

propagate

along

layer

boundaries

or

as

arcuate

"diving

waves"

mainly

sub-horizontally.

The

seismic

signals,

produced

by

controlled

seismic

sources,

are

recorded

along

lines

of

seismometers

deployed

on

land

or

in

the

ocean

(ocean-bottom

seismometers).

Although

this

method

can

also

be

used

in

engineering

geology

for

near-surface

investigations,

we

apply

it

to

analyze

deep

crustal

structures,

the

crust-mantle

boundary

and

the

uppermost

mantle.

Airguns have different chamber sizes, which are chosen in relation to the objectives, i.e. target size and depth. The Refraction Seismic Airguns Cluster consits of usually 4 G-guns with a volume of 8.32 l each, cluster bars as distance pieces and mounting gear. Ocean Bottom Seismometers (OBS) are needed to conduct Refraction Seismic measurements. OBS pool: Henning.Kock@awi.de (Engineer in Charge) or Mechita.Schmidt-Aursch@awi.de (Data Scientist).
