1. Marin Mikrobiologi
Forstå hvordan den mikrobielle sløyfen i det marine næringsnettet fungerer -Hvem er de (Virus, Prokaryote, encellede alger (protister)) ? -Hva gjør de? -Hvordan er sammspillet mellom dem? -Hvordan responderer de mht miljøforandringer?

Activities
Field campaigns NW
Svalbard, different water masses (2015)
SIMCO north of Spitzbergen (2016) (+ samples from N-ICE 2015, NPI)
Young Sound, Greenland (2015)
Field experiments Mesocosms June 2015
Grazing exps (during field campaigns and YS)
Workshops and data analyses
-
Protists: Filter various size classes - for diversity & taxonomic info - pyrosequencing rRNA gene tags (SSU & LSU rDNA)
Metagenomic data from fcm-sorted populations
mRNA to compare gene expression of enzymes involved in the production and consumption of DOC and CO2
Prokaryotes: Filter and extract DNA (history) and RNA (snapshop active community) simultaneously from same sample
Sequencing DNA of a 287 bp-long region within 16S rDNA (V4-5; 519F- 806R) (Illumina MiSeq)
Virus: Concentrate viral fraction - Illumina MiSeq sequencing
Tag sequencing: ssRNA virus (dino- and diatom-virus?),
MCP (phytovirus), PhoH (phages)
Metagenomic sequencing (some samples only)
Structure, function and diversity protist-, prokaryotic-, viral
communities (molecular)
