Species Microsetella norvegica - Distribution map 5Issued from : M. Anraku in Mar. Biol., 1975, 30. [p.82, Figs. 1, 2].
Distribution of hydrological factors and abundance of Microsetella norvegica in Oshoro Bay (west Hokkaido, Japan), 30 August 1958, along vertical section from stations 1 to 5 (distance 650 m).

Nota: The plankton samples were collected by means of a plankton pump during the morning hours at the same time as the hydrological observations. Copepodids and adults were counted ans expressed as number of individuals per 20 l.
The distribution of copepods in a limited area seems to be related to the pattern of oceanographic conditions to some extent, but a pattern of contagious distribution is also apparent. See Barnes & Marshall (1951) ; Cassie (1959) ; Boyd (1973).

Horizontal distribution pattern of Microsetella norvegica (individuals per m2) in the winter North Sea.
Collected by WP2-net. Numbers (ind/m3) depth-integrated, extrapoled to the bottom (but at a maximum to a depth of 500 m) and expressed as ind per m2 of water surface.

Abundance (ind. m3) ± standard deviation of the copepodite stage I-VI of Microsetella norvegica from 2005 to 2010 in SW Greenland near Nuuk.

Nota: Algorithm used to convert body length to body carbon: Equation (Carbon): Ln (µg C) = 1.7843 In (L µm) + In 11.14.
L= prosome length.
During summer, the increase in total copepod biomass was due to higher biomass in M. norvegica. The copepod biomass peaked in August at 71 ± 49 mg C m3; 59% of this was due to M. norvegica

Rem.: Epi-bathypelagic.
Sampling depth (Antarct., sub-Antarct.) : 0-600 m.
Sometimes in brackish water (Chilka Lake in Sewell, 1924; Casamance estuary).
According to Yamazi (1958) the species is common in winter and spring in Tanabe Bay (Japan).
Evans & Diaz (1978, p.313) underline the direct relationship between the size and the temperature in the North Sea.
This form is well represented over the entire length of the Suez Canal.
Observed in ballasts of ships at San Francisco.
After Arendt & al. (2011, p.70) this species dominated the copepod community in the entrance to Godthabsfjord near Nuuk (SW Greenland) at 64°07'N, 51°53'W during 7 months out of a year and makes up > 50 % of the total abundance. However, abundances are low in January-April where M. norvegica make up 32-49 % of the total abundance. From June the abundance of M. norvegica increases rapidly and peaks in July with in average 159.1000 ± 56.000 ind./m3. Due to the massive abundance of M. norvegica it constitutes 95-86 % of total abundance in July-September, respectively, whereas the contribution of other copepods decreases in the same perod. In October M. norvegica numbers decreases to 150.000 ind/m3 until December.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 5 corresponding to small sac-spawning detritivorous.
Ohtsuka & Nishida (2017, p.578) point to the Japanese coasts adjacent to the Kuroshio Current are distinguished by warm-water species M. norvegica.
