    Sample collection methods:
    --------------------------
    Samples were taken between 0600 and 0900 local time. Surface samples were
    taken by plastic bucket and subsurface samples by Van Dorn samplers, usually
    at 6 depths to a minimum of 40 m and more commonly to a depth of 50 m.

    Analyzes methods:
    -----------------
    Photosynthesis was measured in 300 ml volumes of sea water by the carbon-14
    method. Plant pigments were measured in samples having a minimum volume of
    2 litres, using a modification of the Richards method. The procedures descri
    by Strickland and Parsons (1960) were followed.

    Plant pigments were analyzed at sea, using a Beckman DU spectrophotometer.
    The HA milipore filters containing the radioactive plankton for determinatio
    of carbon-14 uptake were glued to copper planchets, stored over silica gel
    and soda lime, and were usually analyzed at the base laboratory ashore. Duri
    surveys P-59-3, P-60-1 and P-60-3, radioactivities were measured aboard ship
    Tests have shown that there is no significant change in activity during the
    6- to 8-week storage period undergone by samples held for analysis ashore.
    Radioactivity was determined in a Tracerlab windowless flow counter.

    The light intensities reported here are taken from transcripts of continuous
    records of solar radiation obtained using an Eppley pyrheliometer.
    Photosynthetic radiation was assumed to be 50% of that measured by the
    pyrheliometer. The complete radiation data are reported in the Monthly
    Radiation Summary published by the Meteorological Branch, Department of
    Transport, Canada.

    Method of incubation of samples for measurement of photosynthesis
    -----------------------------------------------------------------
    Samples were taken from the surface and from 5 depths which matched the
    percentage transmission of light by a graded series of neutral density
    filters. The filters were made of monel screen (McAllister and
    Strickland, 1960), The samples were incubated in daylight beneath their
    matching filters, thus simulating the in situ light intensities to which
    the plants would have been exposed, although not the spectral quality of
    the light.
