Descrição
This data is analysed under a microscope from water samples collected at the Isfjorden-Adventfjorden (ISA) time series station in Svalbard from 2011-14. It ranges from weekly to bi-monthly to monthly data at various different depths from the water column. The samples are generally preserved in Glutaraldehyde stained with Lugol (GLA-Lugol) and stored in a cooling room. The organisms are counted per cubic meter until the species level wherever possible.
Registros de Dados
Os dados deste recurso de evento de amostragem foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 405 registros.
Também existem 2 tabelas de dados de extensão. Um registro de extensão fornece informações adicionais sobre um registro do núcleo. O número de registros em cada tabela de dados de extensão é ilustrado abaixo.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

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.
