Size and abundance data from Pro Mare project,Barents Sea 1984, 1987, 1988.

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 40 records.

2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

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.

Versions

The table below shows only published versions of the resource that are publicly accessible.

Sampling Methods

standard Juday nets (0,36 m opening, 90 µm mesh size) standard WP-2 nets (0.56 m opening, 200 µm mesh size) modified WP-2 nets (0.56 m opening, 90 µm mesh size) submersible plankton pumps "Hufsa" owned by IMR (Bergen; 90 µm mesh size) and University in Tromsø ( 200 µm mesh size). Opening diameter 0.25 m. Some samples were shared with other researchers - the fraction I received has been weighed into "fraction counted"

Method step description:

1. Metadata station data from files, notes and cruise reports Abundances count data from calculation files checked against hand-written raw data. Only numerical values above zero and presence data are noted. Data calculated per square m sea surface and down to sampling depth. Depth has been corrected for towing angle, when necessary. Abundances per square m Count data for split water-column (cruise 10, st 6 & 7) and Hufsa pump-samples at discrete depths (cruise 10, st 7, and cruise ED = Endre Dyrøy) Microscope_Pseudocalanus prosome lengths from formalin-preserved samples.

University of Southern California, Department of biological sciences. 254 pp. Length of Microcalanus sp adult females overlap mostly with M. pusillus. There is a small overlap of the size distributions between M. pusillus and M. pygmaeus Stained_Pseudocalanus Size measurements (digitized) from formalin fixed, stained and dehydrated copepods in cedarwood oil. Stained_Microcalanus Size measurements (digitized) from formalin fixed, stained and dehydrated copepods in cedarwood oil. Samples from stained samples Stained samples were preserved in formalin, then stained with borax-carmine and dehydrated and transferred to cedarwood oil. This procedure decreased sizes by ca 24% by length (Norrbin, 1994). These contain data on prosome length, width and area, gonad area (sometimes length and width) gonad development stage, oil sack area, sometimes gut contents, and sometimes also visible eggs (oocytes) or diverticulae Described in e.g. Norrbin (1991) listed above and Norrbin (1994)
