Figure 3. Depth profiles of Northern Baffin Bay Stations 129, 123 and 109.

Density (sigma theta) is indicated by the solid black line, circles embedded in these lines show sample depths for DNA and RNA (open circles) and for DNA only (filled circles). In situ chlorophyll fluorescence (relative units) is shown by the green line and oxygen concentrations (μmol kg ⁻¹) by the dotted line.
