  • Sunscreen identified as major cause of coral bleaching

    New research highlights the harmful effects of sunscreens on coral reefs. The ultra-violet (UV) filters, used to protect skin from the harmful effects of sun exposure, caused bleaching of coral reefs even at very low levels. In areas exposed to high levels of human activity, sunscreens may now be posing a significant risk to marine life. Coral reefs are among the most biologically productive and ...

  • 20 years of monitoring provides insight into New Zealand`s river water quality

    Two decades of monitoring of river water quality by NIWA has provided important information that is helping to care for New Zealand’s iconic rivers.
