Our climate is changing - we need to act now.
Glaciers Don't Lie
If you think New Zealand's Southern Alps are shielded from climate change – take a look at this. "You can't make a glacier lie.”
Dr Yoann Ladroit, Whakaari TAN2007 Voyage
Marine Acoustician Dr Yoann Ladroit is leading research into using acoustics to find underwater gas bubble flares and then compare these to the chemical composition of water samples taken at the same locations.
Alex Hayward, Whakaari TAN2007 Voyage
Measuring chlorophyll, organic nitrogen and carbon levels, PhD student Alex Hayward looks at how much marine life is in the water around the Bay of Plenty during winter.
Arne Pallentin, Whakaari TAN2007 Voyage
NIWA marine geologist Arne Pallentin is looking for telltale gas bubble 'flares"—using a multi-beam echo sounder—that indicate new volcanic activity in the Calypso Vent Field.
Dr Kura Paul-Burke, Whakaari Voyage
"For us, Whakaari is our whaea, she is our tupuna, and also a place of our mahinga kai. I didn't realise how much I'd missed her..."
Joshu Mountjoy, Whakaari Voyage
Marine geologist - Dr Joshu Mountjoy - is mapping the seafloor landscape around Whakaari/White Island to understand how much sediment was dislodged in the eruption and where it has gone.
Sally Watson, NIWA marine geophysicist
Marine Geophysicist Sally Watson, maps the seafloor and takes samples from the water column so we can understand geological processes shaping the volcanic underwater realm around Whakaari/White Island.

SHMAK Water Quality – Phosphate
Phosphate is measured in SHMAK using the Hanna Instruments Phosphate Checker. Where to order phosphate checkers and reagents.
SHMAK Water Quality – Nitrate
The nitrate test included in SHMAK is a colorimetric test. Where to order additional Aquaspex Microtest® Nitrate-N kits.
SHMAK Water Quality – Temperature and Conductivity
Temperature and conductivity are two easy measurements you can take in your stream. Here's how to use a temperature logger.
SHMAK Water Quality – Visual Clarity
There are two methods to determine visual clarity in SHMAK; the clarity tube (or SHMAK tube) and the black disc method.
How to Collect a Water Sample
Some SHMAK tests require you to collect a water sample. If you are sending your water sample to a lab for analysis, here's a list of some water quality labs.
Setting up your Site
The various assessments in SHMAK are done over different lengths (reaches) of stream. Mark out the longest reach first, then shorter reaches.
What is Included in SHMAK
SHMAK is available as a starter kit, a standard kit and SHMAK+. Here we explain what is included in the kit and what extras you need to purchase on your own.
SHMAK Stream Life – Periphyton
How you can assess the types and amount of periphyton: communities of algae and cyanobacteria attached to the sediment surface or plants.
