The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv,.esriCsv,.geoJson,.odvTxt
attribute NC_GLOBAL acquisition_description String Methodology:
Plankton samples were collected from discrete depths during CTD casts using
a high-capacity, diaphragm pump with an intake hose mounted to the CTD
Rosette. Subsamples of sample contents were manually counted, identified, and
measured in the laboratory

Sampling and analytical procedures:
For each sample, the pump was run for a timed period of nominally 5 min. The
flow rate of the pump was usually measured immediately prior to sampling, by
recording the time required to fill a barrel of known volume. Samples were
preserved and stored in 5% buffered formalin. The laboratory protocol was to
separate samples into two size fractions by passing them through large (200 or
500 \u03bcm) then small (64 \u03bcm) mesh sieves; split, dilute, and sub-
sample each size fraction as needed; count and identify all plankters (minimum
n = 50) in each subsample; and estimate the length and width of exactly 100
plankters (the first 50 from the large and small fraction, respectively) to
the nearest 50 \u03bcm using a dissecting microscope. Three replicate small
size fractions per sample were processed starting in 2006.

Data column "vol" was calculated as follows:
vol =

Data column "flag" contains the following codes:
flag 1: length & width were not measured, but estimated from similar samples
flag 2: shallow & deep samples not labeled, but deduced from sample contents
flag 3: depth estimate less accurate than usual (\u00b1 ~3 m)
flag 4: time estimate less accurate than usual (\u00b1 ~15 min)
flag 5: pump flow rate estimated by nominal flow rate

attribute NC_GLOBAL instruments_0_description String The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column and permits scientists observe the physical properties in real time via a conducting cable connecting the CTD to a deck unit and computer on the ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast. This instrument designation is used when specific make and model are not known.
