Dr Sara Mikaloff-Fletcher is looking to turn the internationally accepted science of monitoring greenhouse gas emissions upside down – and the rest of the world is watching closely.
A breakthrough in understanding about the causes of climate change has today been published online in the prestigious international journal Science.
The World Meteorological Organisation Congress has confirmed NIWA's Lauder atmospheric research station as one of Earth's leading providers of upper-air data critical for measuring climate change.
Now back on dry land, Voyage Leader Richard O'Driscoll reflects on the final days of RV Tangaroa's 2015 Antarctica expedition.

This project will demonstrate the commercial feasibility of producing bio-oil by the conversion of algae biomass that has been grown in wastewater treatment facilities. In particular we aim to maximise algae production in High Rate Algal Ponds (HRAP) by adding carbon dioxide, and demonstrate energy efficient conversion of algal biomass to bio-oil.

In a small green laboratory perched on the rocky volcanic southern peninsula of Ross Island, Antarctica, there’s a space waiting for a new shiny, hi-tech Christmas present.

Not warming to climate change

The latest climate change reports from the Intergovernmental Panel on Climate Change (IPCC) reinforce the urgent need to reduce global greenhouse gas emissions as well as to adapt to the impacts of climate change. Michelle Sutton finds that the news is mixed for New Zealand’s agricultural sector.
A range of trace gases are measured continuously at Baring Head, New Zealand. Observations at this station were started in the early 1970s and continue to the present.

Scientists have discovered an abrupt increase in the uptake of atmospheric carbon dioxide by the land biosphere since1988. Without this natural increase in uptake, the amount of carbon dioxide in the atmosphere would probably have increased even more rapidly over the last two decades.

You might think that because all the carbon in cattle farming comes from the grass that the cattle is fed on, then the beef produced should be carbon neutral. But this is not the case.

Is ocean iron addition part of the solution to climate change? Cliff Law, NIWA explains: 

Lauder celebrates 50 years of atmospheric research.

The return of the upgraded RV Tangaroa represents a huge advancement for New Zealand science and exploration

NIWA today welcomed home RV Tangaroa, New Zealand’s only deepwater research vessel, after a $20 million dollar upgrade to enhance its ocean science and survey capabilities.

The statement made by NIWA Principal Scientist, Dr Keith Lassey in a TV3 news story about methane (22 Dec 2009) is correct.

The concentration of methane in the atmosphere is rising, according to measurements made by NIWA.

NIWA has today released measurements from its globally significant Baring Head station showing that southern hemisphere atmospheric methane increased by 0.7% over the two-year period 2007–08. While this increase may not sound like much, it is about 35 times more than all the methane produced by New Zealand livestock each year.

This schematic shows how greenhouse gas measurements are made for the Total Carbon Column Observing Network at NIWA's Lauder Atmospheric Research Station in Central Otago, New Zealand.

This is a description of technical terms used in the Total Carbon Column Observing Network project page.
