Abstract:
One sediment echosounder profile from the Cartwright trough, a glacial cross-shelf trough of the Labrador Shelf, is presented. The profile was collected on board the Maria S. Merian during the cruise MSM45 using the Teledyne Parasound P70 parametric sub-bottom echosounder mounted on the hull. A secondary low frequency of 4 kHz was used. Data was converted from the PS3 recording format to the SEGY format using the software ps32sgy written by Hanno Keil (University Bremen). The conversion included mean subtraction, time-domain filtering (pass from 2 to 6 kHz) and calculation of envelopes. The objective of data recording on the Labrador Shelf is to map glacial landforms and reconstruct the dynamics of the Laurentide Ice Sheet in detail.
