Forskningsområde
Jeg arbejder bredt med transport, produktion og omsætning af organisk materiale og næringsstoffer i akvatiske miljø.
Det inkluderer blandt andet:
- Primær produktion i havis og sedimenter
- Mikrobiel omsætning i sedimenter fra kystzonen til de største dybder i oceanerne
- Omsætning og dynamik i synkende partikler
- Zooplankton og stof omsætning
- Eeffekter af temperatur, hydrostatisk tryk, vandflow for udveksling og omsætning af materiale
- Sediment re-suspension
- Betydning af faunaadfærd for materialiseringsprocesser og stofudveksling
Nøgleord
- Biogeokemi
- Mikrobiologi
- Klimaforandringer
- Mikrosensorer
- Dybhav
- Sedimenter
- Marin sne
- Fotosyntese
- Undervandsrobotter
