Description
Summary:Data provides the date, time and 10 min cumulative erythemal irradiance at Davis Station for downwelling solar radiation and the irradiance at depth beneath neutral density screen (ND-polythene) and 3.3, 5.5, and 9.0 mm borosilicate glass. These light treatments simulated water column depths of 1.0, 2.0, 3.0, and 3.6 m depth (calculated using Beer's Law and the average UV transmittance of Antarctic seawater at 4 ice-edge sites). A no erythemal UV control (transmittance greater than 375 nm) was also used in which samples were incubated beneath UV-stabilised polycarbonate. The fields in this dataset are: date Davis solar time downwell wnd w3.3 w5.5 w9
