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)
