  1. JR245 (WCB)/JR246 (HS)/JR247(AFI-KRILL)

  2. Primary objective: KRILL Primary method: Target fishing AFI-KRILL Science: Krill nutrient cycling iron chemistry Personnel: Angus Atkinson (BAS) Katrin Schmidt (BAS) Hugh Venables (BAS) Christian Schlosser (NOC) Sophie Fielding (BAS) Peter Enderlein (BAS) Equipment: RMT8 MOCNESS/Ring net (backup) GO-FLO SAPs Towed iron fish EK60/ADCP WCB Science: WCB krill biomass Mooring deployment/recovery EK60 calibration Personnel: Gabi Stowasser (BAS) AN Other (BAS) Sophie Fielding (BAS) Peter Enderlein (BAS) Equipment: RMT8 EK60/ADCP Moorings AFI-CGS Science: Thermal tolerance krill Personnel: Geraint Tarling (BAS) Magnus Johnson (Uni Hull) AN Other (?) Equipment: RMT8 MOCNESS Total personnel 8 (11 with the 3 unconfirmed)+ 1 NMF + 1 directorate

  3. Sampling strategy: AFI-KRILL Task Time Locate a krill swarm acoustically ? Target fish with an RMT8 (require >100 live and kicking krill) 1 hr Acoustic grid to locate swarm again 2 hr SAPS deployed through krill swarm 5 hr CTD (chl sample from krill swarm depth) 1 hr GO-FLO profile 3 hr Total 12 hr + ? Sampling strategy: WCB Task Time Mooring recovery (P2,P3,WCB) 12 hr each Mooring CTD 3 hr each Mooring deployment (P2,P3,WCB) 12 hr each 8 acoustic transects 4 hr each 6 CTDs 9 hr 6 RMT8 oblique hauls (1.5hr each) 9 hr EK60 calibration 12 hr Target fish with an RMT8 24 hr Transit ? hr Total 167 hr + ?
