Multibeam

Who are you ?

I’m a 26-years-old PhD student from Norway. working at the University of Tromsö, Norway. I have studied geophysics, and now I’m working in Trosmö since 2 years. I’m also teaching a course called “Introduction to sedimentology” at this university.

Can you describe us your job ?

My PhD thesis is on submarine mass movement and its processes. One of my study areas is an old submarine slide called the Andøya slide, located along the NW-Norwegian coast. I compare geophysical data (bathymetry, seismic profiles…) with geological data (sedimentary cores)

Why did you choose this job ?

When I was at High school, I found geology very interesting. I’m also curious about different subjects of this science.

What will be your tasks during the cruise ?

I will produce records with different geophysical information. On this cruise, we have an echosounder, which works like a SONAR. It’s the same device usually used by fishermen to detect fish. However, we will use it in a different way than them ! We will also use a multibeam instrument, which is able to map the ocean floor. Finally, we will use a sub-bottom profiler, which can produce images of the first tenth to hundreds meters of the sediment cover.

What do you like (most) in your work ?

I like 2 different parts on my work : At first, I like discovering of something new, because we often explore unknown areas. Secondly, when you collect the data, and after that, you connect this data to something wider, then we can increase our understanding of the world !
