說明
The present phytoplankton dataset was obtained during seven surveys aboard the R/V Noruega from IPIMAR, as part of the project “Dinâmica do Fitoplâncton tóxico na costa portuguesa”. The campaigns took place from July 89 to March 95.

地理涵蓋範圍
Campaigns covered the coastal area of Portugal, from Caminha to V.R. Sto António (1989 to 1992), and along four transects perpendicular to the coast, numbered from 00 to 03, starting from the southern coast to the northern coast (1994 and 1995).

取樣方法
For the qualitative and quantitative analysis of phytoplankton from these six surveys, 250 ml samples of seawater were collected and placed in brown plastic bottles.
| 研究範圍 | From 1989 to 1992 - At each sampling station, depth levels of 0 and 20 meters were sampled using "Nansen" bottles. In 1994 and 1995 - At each sampling station, depth levels of 0, 10, 20, 30, 50 and 75 meters were sampled using "Nansen" bottles. |
|---|---|
| 品質控管 | The samples were in situ preserved with 20% formalin, neutralized with hexamethylenotetramine (previously placed in the bottle), resulting in a final concentration of 0.4%. |
方法步驟描述:
- In the laboratory, subsamples of 100 ml were placed to sediment in counting chambers for 72 hours. Phytoplankton enumeration was performed using the Utermöhl technique, on a ZEISS IM35 inverted microscope equipped with bright field and phase contrast.
