Originally published on GBIF.org - https://doi.org/10.15468/jhkb5u This dataset is the result of a radiolarian sampling program from Korsfjorden (60.19110 N,5.23136 E), on the west coast of Norway near Bergen, that took place from November 1969 and ended in May 1971. At the sampling location the fjord depth is 670 m. The water column was divided into 100 m depth zones (100-0 m, 200-100 m, ….600-500 m, and 650-600 m) except for the deepest zone where the sampling started ca. 20 m above the mud line to avoid contamination of the net. At each sampling date all depth zones were sampled. A plankton net with 63 µm mesh opening was used. This dataset also includes the phaeodarians found in this dataset. A total of 72 species was observed. A discussion of this dataset can be found in: Bjørklund, K.R., 1974. The seasonal occurrence and depth zonation of radiolarians in Korsfjorden, Western Norway.
