Info

Besides a general charting of sediment characteristics along the Mud Volcano, the PARASOUND data will give information on the classification and interpretation of sediment types. The sediment echo sounding of cruise ARK XIX/3b has been performed for the AWI geochemistry working group. B. 3.4 Marine Geology Kukina, N. During the scientific expedition ARKXIX/3b 12 geological stations were carried out in the Håkon Mosby Mud Volcano area (Tab. B3.4-1) in the framework of the project described herein. More than 40 samples of bottom sediments were taken for future investigation at the Murmansk Marine Biological Institute (MMBI) of the Russian Academy of Science. Sedimentological investigations included granulometry, mineralogical analysis and morphology of quartz grain. Tab.

B3.4-1) with Giant Box Corer (GKG; 50x50x60 cm) and Multicorer (MUC) with eight tubes of 10 cm in diameter. Sampling of long sediment cores The gravity corer was used to obtain long sediment cores. The length of obtained - 177 -
sediment cores varies between 166 to 485 cm. Six gravity cores were opened, photographed, discribed and sampled onboard RV “Polarstern” (Fig. B3.4-1a-f). Sediment colors were identified with the “Munsell Soil Color Chart”. Preparation and examination of smear-slides from sediments have been done on board. Results of smear-slides examination are represented in Table B3.4-2. For lithological descriptions see Fig. B3.4-1a-f. Tab.
