Dose rate (KJm⁻² h⁻¹) and total dose (KJm⁻²) of UV-B, UV-A and PAR provided to larvae.

<p>Cod larvae (<i>Gadus morhua</i>) were exposed to two different light conditions (UV-B and Control) for 15 hours before the behavior experiments. Measurements were made at the surface of the water in the exposure tanks.</p

Spectral irradiance for the 3 treatments: PAR (solid line), PAR plus ambient UVR (dotted line), and PAR plus enhanced UVR (dashed line) measured inside the Teflon bags that were used for culturing the algae.

Daily irradiance of UVB, UVA and PAR provided to <i>Thalassiosira weissflogii</i> cultures used as food for <i>Calanus finmarchicus</i>.

<p>Algal cultures received one of three treatments: PAR-only (PAR), PAR plus ambient UVR levels and PAR plus enhanced UVR (UVR+).</p

Schematic of the test tank and funnel insert.

<p>Once the release device is lowered into the tank, the eel is able to come out in any direction. Its escape direction (where it touches the water surface along the slopes of the funnel) is recorded as a bearing.</p
