Multibeam system 7 - Equipment performance

3. FIELD OPERATIONS

3.2. Equipment performance

3.2.2. Multibeam system 7

The EM1002 system was not used during the cruise due to the large water depth of the surveyed areas. The EM300 functioned optimal throughout the entire cruise.

3.2.5. Gravity Corer

The gravity coring system functioned very well all the time. Gravity coring was performed at a number of locations and was recovered successfully.

3.2.6. Box Corer

The box coring system functioned very well all the time. Box coring was performed at a number of locations and was recovered successfully.

3.3. General cruise performance

 The weather conditions were good throughout the survey period.

 The data collected during the cruise can be summarized as (Table II-V):

o 3 CTD stations o 4 gravity cores o 3 box cores

o A total of 255 km of multibeam and TOPAS data:

 88 km in Fensfjorden

 115 km in Bjørnafjorden

 52 km in Byfjorden
