in the fiord showed not so reach life in pelagial. No bloom, not so many zooplakton.
Seems that bloom starts outside Isfjorden

Spring field sampling activity in Polish GAME Project  April/May 2013

Aim of the sampling activity: to collect samples of zooplankton and protoplankton (autotrophic and heterotrophic plankton) communities, to collect water samples for chlorophyll concentration, and to do measurements of water temperature and salinity and light attenuation in spring and in the two fjords being compared in the GAME Project.

Coordinates of the preferable sampling stations.

Hornsund: Station name H2 (long term monitoring station) 76.9841°N, 015.7651°N, depth ~200 m. If not accessible then a substitute station in the middle of the fjord, towards the entrance, Name H2+, approximately at 76.96°N, 015.53°E, depth ~200 m, or another suitable place in the central part of the fjord.

Kongsfjorden: Station name K3 (long term monitoring station) 78.9555°N, 011.9320°N, depth ~300 m. If not accessible then a substitute station in the middle of the fjord, towards the entrance, Name K2, 78.9780°N, 011.7059°E, depth ~300 m, or another suitable place in the central part of the fjord.

Sampling/measurements at the station.

CTD profile throughout the water column (surface/bottom).

Light attenuation measurement with Secchi disk.

Zooplankton sampling. Aboard small boat  with WP2 net (mesh size 0.180 mm), preferably in strata: bottom-50, 50-10, 10-0 m; Aboard Helmer Hanssen, with Multi Plankton Sampler (MPS, mesh size 0.180 mm (0.200 mm); in Hornsund: bottom-150 m, 150-100 m, 100-50 m, 50- 10 m, 10-0 m; in Kongsfjorden: bottom-200 m, 200-100 m, 100-50 m, 50- 10 m, 10-0 m. Zooplankton sample fixed with formaldehyde, 4% final concentration in sea water. Provide sample with sample label on copying paper (including at least sample number, station name, sampling depth, date of sampling) and if possible label the sample bottle with key information about the sampling.
Phytoplankton sampling (regardless from boat or ship). Net phytoplankton sampling  with Phytoplankton net (mesh size 0.02 mm), vertically integrated tow from 30-0 m. Phytoplankton net sample fixed with Lugols solution (~ 0.5 - 1 % final concentration, in practice, 0.5  1.0 ml Lugols solution in 100 ml of sample volume), after 24 hour add formaldehyde (~2% final concentration, in practice, 5 ml of 36% formaldehyde in 100 of sample volume). Provide sample with sample label and label the sample bottle (see zooplankton sampling).
Water sampling for quantitative phytoplankton samples and chlorophyll concentration measurements  with water bottle from fixed depths (0, 3, 7, 15, 25, 30 m), quantity of 1000 ml of sea water poured into transport bottle and stored in cooled and dark place until brought to lab asap.
Quantitative phytoplankton sampling  in the lab shake well the water sample in the transport bottle, collect quantity of 250 ml of sea water taken with water bottle at a station from fixed depth, quantity placed in sample bottle (dark?), fixed the same way as phytoplankton net sample (with Lugols solution and formaldehyde). Provide sample with sample label and label the sample bottle (see zooplankton sampling).
Sampling for chlorophyll concentration  in the lab shake well the water sample in the transport bottle, filter known amount of water (from 50 to 250 ml) through Whatman GF/F filter until the filter turns greenish (note the water volume filtered). After completing filtration of a sample, fold the filter, blot it and wrap in aluminum foil. Put the filter in zip bag, provide with sample label on copying paper and store in bio-freezer or in a regular freezer (min -20°C).

Carry on notes from field and lab activity with information on sampling, measurements, sampling conditions (ice, weather), deviations from procedures etc. Take PICTURES and collect facts for expedition blog!!!.

We plan coastal expeditions in spring 2013 (see the photo of that type of work from Rijpfjorden, in cooperation with Norsk Polarinstuitutt) and summer r/v Oceania cruise to the fjords (see the photo of summer work from Hornsund)
