Water & Atmosphere

As a project to celebrate the creativity of the Principal Scientists at NIWA in Hamilton, David Roper and Stephanie Parkyn have created a series of photographs that depict the inspirations behind the scientists’ work. ‘Waterworks’, on the front cover, refers to Dr Chris Tanner’s pioneering use of constructed wetlands to treat wastewaters. See the images created for the other scientists at Inspired minds: curiosity and imagination in science. Read more about Vol.17 No.1- March 2009

Marine biofouling creates a huge headache for New Zealand aquaculture. Read about a promising new technology for controlling biofouling. Read more about Vol.16 No.4 - December 2008

Jordy Hendrikx makes a measurement at Arthur’s Pass to validate and calibrate snow depth observations in NIWA’s new Snow & Ice Network. Read more about Vol.16 No.3 - September 2008

RV Tangaroa in newly formed ice in the northern Ross Sea. Scientists from NIWA and other institutions travelled for seven weeks and covered more than 7000 nautical miles to sample Antarctic marine life. The back cover shows the ship’s track and sampling stations. Read about the voyage and see some of the finds in 'Back from the ice bearing scientific treasure'.

Berthing at Aotea Wharf in Wellington, NIWA's research vessel Tangaroa is readied for another voyage as part of the Census of Marine Life. CoML is an international initiative involving more than 80 nations in a 10-year effort to assess and explain the diversity, distribution, and abundance of life in the oceans.

A moon jelly drifts past a line of cultured mussels while NIWA scientists set up experiments nearby. They are exploring the benefits of integrated co-culture, where the waste from one species is food for one or more other cultured species. Read more in 'Finding hidden treasue in aquaculture waste'.

Flooding in March 2007 forced Northland farmers to move stock to higher ground; the same region was hit again in July. This special issue looks at ways that hazard forecasting can lessen the blow for communities caught in the path when nature turns nasty. Read more about Vol.15 No.3 - September 2007

A novel twist on existing technology gives NIWA scientists greater scope for using sediment colour to divine what’s happening at the microbe level. Read how this new technique is being used to track environmental damage and recovery in the article Colourful seafloor. Read more about Vol.15 No.2 - June 2007

Though ozone declines have slowed globally (and in some cases have ceased), here in New Zealand we’re still subject to very high levels of UV radiation and must take care when we go out in the sun. Read about the latest WMO/UNEP ozone assessments. Read more about Vol.15 No.1- March 2007
