People behind the scenes: marine geologist Outi Hyttinen

Hello, I work as a marine geologist at the Geological Survey of Finland, in Espoo. Within the SEAmBOTH project I have interpreted sidescan sonar and seismic reflection data, in order to know what type of sediments the study area seafloor consists of. During the field season, my collegues collect information onboard, which we during the winter will process and interpret. Northern Bothnian Bay was a new geological environment to me, and it is really an interesting place!

Previously I have worked e.g. with Baltic Sea Basin deglaciation history and with laminated clays in southern Finland. This involved e.g. digging deep into clay or spending time on a research vessel. Sometimes you could end up in a sand pit. As you can see, fieldwork is always a good fun!

Marine geology has always interested me. The final push towards watery direction from more terrestrial activities was participating an International Ocean Discovery Program (IODP) expedition at the Baltic Sea in 2013.

After almost two months onboard, the world of research never looked the same. Maybe it was a lure of Neptune.
