Svinøy Section Sampling Program - IMR Standard Procedures for Long-Term Monitoring

The Svinøy standard section sampling program involves repeated sampling five times a year in various months to monitor hydrography, nutrients, phytoplankton, and zooplankton. The program includes specific sampling protocols for different parameters at different depths and stations to facilitate comprehensive data collection and analysis. Furthermore, additional sampling activities such as macroplankton trawling and multi-frequency acoustics are conducted to enhance the understanding of marine ecosystems in the area.

  1. IMR Standard Section Svinøy Sampling program

  2. IMR Standard sections and fixed stations • Svinøy standard section: • Repeated 5 times per year • Januar, March, May, July, November • Objectives: • Long term monitoring of • Hydrography • Nutrients • Phytoplankton • ooplankton

  3. Standard sampling program on Svinøy section

  4. Sampling program • Zooplankton • WP2 (180 mµ) 0-200m at all stations • 1 m2 Mocness (180 mµ) to bottom at selected stations (if weather and cable permits) • 50% of sample on formalin • 50% of sample: Biomass size fractions >180, >1000, >2000 (extracting krill, amphipods, shrimps, fish,+) • Phytoplankton • Chlorophyll samples down to 100 m • Phytoplankton species: Water samples (0-30 m) from the bottles (lugol) • Phytoplankton species: 10 mµ net haul (30-0m) (20% formalin) • Secchi • Nutrients • 12 water bottles • Nutrient samples from all depths • Nitrate, Nitrite, Phosphate, Silicate (ammonium is possible) • Hydrography • CTD with Fluorescence, oxygen, Light, Ph (to bottom at all depths • Thermo-salinograph (T, S, Fluorescence) • Weather station data...

  5. Additional sampling at Svinøy • Macroplankton trawl for macroplankton and micronekton • Mulitfrequency acoustics (fish, macroplankton, micronekton) • ADCP • Applied for two days extra on the Svinøy section for BASIN • Standard program takes about two days... • Challange: we do not know what ship will be used yet... • GOSars about 25 berths for scientists. Standard IMR scientific crew on Standard sections are 4 persons. • Johan Hjort ? • Håkon Mosby ?

  6. Database • IMR database holds: • hydrographic data, including fluorescence • Nutrient and chlorophyll data • Zooplankton data (nets and macroplankton trawl) • Fish data (trawl) • Acoustic raw data and scrutinised data • Data from towed platforms (CTD, fluor., OPC, Acoustics, VPR self contained)

  7. BASIN cruise June 2012 • 13 days with G.O. Sars in early June 2012 (Confirmed by IMR cruise committee) • Time to be shared with other projects (INDIPOP, ++?) • Arctic front between Iceland and Jan Mayen

  8. BASIN Cruise objectives • T5.1.2 Spatial structure in small pelagic fish populations, Atlanto Scandic herring, blue whiting and mackerel • Migration of herring in relation to zooplankton dynamics at the Arctic front • Cruise activities will focus on the continuous monitoring of high resolution 3D distribution of hydrography, fluorescence, size resolved zooplankton, and fish.

  9. MUST and MESSOR Mulitfrq. Acoustics, VPR, L-OPC, F-CTD...
