Métodos de Amostragem
Nisking bottles were used to collect sea water samples for microscopy data, which were later fixed with Glutaraldehye-lugol and refrigerated at UNIS, Svalbard. Samples were collected from various depths 5,15,25,60m for all three years.
Área de Estudo | The sampling was conducted once every week in 2012 followed by once every two weeks in 2013 and once every month in 2014 at the IsA timeseries station in Svalbard. |

Descrição dos passos do método:
- Stored and fixed samples were then sent to IOPAN for microscopic analysis. Samples were prepared according to Utermohl method. 50 ml of the pelagic subsamle was sedimented in 50 ml cylinder attached to the utermohhl base plate for 24 hrs. This was kept in a cool, shaded place (to avoid convections). The sample was then analyzed by counting cells in the microscope's fields of view in transects through the bottom of the chamber. 50 dominant cell taxa were counted. At 100x magnification, transects usually covered most of the slide area and at 400 or 600x, counts were made in three transects (1 crossing middle and 2 on the sides of the chamber). The abundance was calculated taking into account the number of cells counted, the so-called chamber factor (the ratio of the field of view to the chamber area) the volume of the subsample used for sedimentation and the number of fields of view.
