The springtime stratospheric ozone (O3) layer over the Antarctic is thinning by as much as 50 percent, resulting in increased midultraviolet (UVB) radiation reaching the surface of the Southern Ocean. There is concern that phytoplankton communities confined to near-surface waters of the marginal ice zone will be harmed by increased UVB irradiance penetrating the ocean surface, thereby altering the dynamics of Antarctic marine ecosystems. Results from a 6-week cruise (Icecolors) in the marginal… 

Ultraviolet Radiation and Bottom‐Ice Algae: Laboratory And Field Studies from Mcmurdo Sound, Antarctica

Springtime ozone depletion in the Antarctic has allowed high levels of ultraviolet radiation to reach the Earth's surface, and this may adversely affect the productivity of phytoplankton growing in

Inhibition of marine photosynthesis by ultraviolet radiation: Variable sensitivity of phytoplankton in the Weddell‐Scotia Confluence during the austral spring

The results suggest that nonlinear exposure-response relationships are necessary for modeling UV-dependent photosynthesis in the surface mixed layer of the springtime Weddell-Scotia Confluence, and modified the laboratory-based model of photosynthesis and photoinhibition to describe photoin inhibition as a nonlinear function of biologically weighted cumulative exposure to damaging irradiance.

ULTRAVIOLET RADIATION IN ANTARCTICA: INHIBITION OF PRIMARY PRODUCTION

With the seasonal formation of the ozone hole over Antarctica, there is much concern regarding the effects of increased solar UV‐B radiation (280–320 nm) on the marine ecosystem in the Southern

Impact of a deep ozone hole on Southern Ocean primary production

[1] Field studies show that photosynthesis by Antarctic phytoplankton is inhibited by the increased ultraviolet radiation (UVR) resulting from springtime stratospheric ozone (O 3 ) depletion. To

Influence of Ozone-Related Increases in Ultraviolet Radiation on Antarctic Marine Organisms

SYNOPSIS. Every spring for the past two decades, depletion of stratospheric ozone has caused increases in ultraviolet B radiation (UVB, 280–320 nm) reaching Antarctic terrestrial and aquatic

Influence of Ozone-Related Increases in Ultraviolet Radiation on Antarctic Marine Organisms1

Abstract Every spring for the past two decades, depletion of stratospheric ozone has caused increases in ultraviolet B radiation (UVB, 280–320 nm) reaching Antarctic terrestrial and aquatic habitats.

Transparency of Antarctic ice‐covered lakes to solar UV radiation

Depth profiles of solar ultraviolet radiation (UVR), photosynthetically available radiation (PAR), and related variables were measured beneath the thick, permanent ice cover of four lakes in the

Interactive effects of ozone depletion and vertical mixing on photosynthesis of Antarctic phytoplankton

Photosynthesis of Antarctic phytoplankton is inhibited by ambient ultraviolet (UV) radiation during incubations, and the inhibition is worse in regions beneath the Antarctic ozone ‘hole’. But to

UV radiation and potential biological effects beneath the perennial ice cover of an antarctic lake

High-resolution spectral scans of solar ultraviolet radiation (UVR) were obtained directly beneath the 4.0–5.0 m thick, perennial ice cover of Lake Hoare, South Victoria Land, Antarctica. Both UVA

Ultraviolet radiation, ozone depletion, and marine photosynthesis

Results show that although UVB photons are more damaging than UVA (320–400 nm), the greater fluxes of UVA in the ocean cause more UV inhibition, and models can be used to analyze the sensitivity of water column productivity to UVB and ozone depletion.

Ultraviolet Radiation Levels During the Antarctic Spring

Model calculations show that UV irradiances encountered during the occurrence of an Antarctic "ozone hole" remain less than those typical of a summer solstice at low to middle latitudes, but the low ozone amounts observed in October 1987 imply biologically effective irradiances for McMurdo Station, Antarctica that are comparable to or greater than those for the same location at December solstice.
