NIWA Blake Ambassadors Vlog 3: Fishing for water!

7 November 2018. In this Vlog 2 update live from Tangaroa, NIWA Blake Ambassador Siobhan O’Connor shares a typical shift, starting at 2.30am, collecting water samples from different ocean depths which are carefully analysed in the lab. 

Timelapse from RV Tangaroa cutaway 12 hours

27 October 2018. A 12 hour time lapse from the cutaway deck on the RV Tangaroa.

To make sure that we are using our time on the ship as efficiently as possible, we have two shifts of scientists and crew working around the clock, either midnight-midday or midday-midnight. This often means that there are some members of the team who you barely cross paths with!

We are currently sampling a water mass where salps are present, which means that we are using a variety of nets to sample at different depths, and for different sized organisms. We are also collecting other environmental parameters with a CTD, which measures the salinity, temperature and depth of the water, and also allows us to collect small pockets of water from a range of depths.

26 October 2018. NIWA Blake Ambassadors, Lana Young and Siobhan O'Connor and SalpPOOP voyage leader Dr Moira Decima check out sampled salps from different depths.

Students at Leigh School have been working with marine scientists and the 'Year of the Salps' project partners to learn how to count sea salps, understand salp life cycle phases and the importance of salps in marine ecosystems and their carbon-cycling effects on climate change.
Who is involved in the TAN1810 SalPOOP voyage?
The RV Tangaroa heads out to the Chatham Rise and the east coast of the South Island on 23 October 2018. The TAN1810 voyage will focus on the special role salps play in carbon cycling, and where they fit in marine food webs off the New Zealand coast.

Think about a futuristic world where at night time, people use different kind of self-propelled vehicles to hover across cities, illuminating the skies with different colours and shapes, while transiting around them.

Breakfast with Ebony - Episode 3

Marine Biologist Diana Macpherson spends a good part of her time investigating various critters that live on the sea floor...check out this enormous specimen!

NIWA’s Marine Invertebrate Collection has welcomed two extremely rare octopus that have only just been provisionally identified.
An interactive guide to the intertidal sponges of New Zealand.

Pollen from New Zealand pine forests has been shown to travel more than 1500km through wind and ocean currents, and sink thousands of metres into the ocean to reach some of the world’s deepest ecosystems.

This week we feature a community of critters living on the Chatham Rise sea floor.

Recording underwater biodiversity after earthquakes

NIWA’s marine ecologist Dr Dave Bowden talks about the catastrophic changes to the seafloor in the Kaikoura Canyon following the November 2016 earthquake.

Our Critter this week is Uroptychus tracey (Ahyong, Schnabel & Baba, 2015)—newly described in a 2015 paper reviewing the squat lobster fauna of the Macquarie Ridge.

A voyage to the Kermadec Islands has resulted in the discovery of many species either new to science or not previously found in the area.
This year is the 2400th anniversary of the birth of Aristotle, a philosopher and scientist (384 BCE), who among other many great achievements was the first person to describe the structure, ecology, and diversity of sea urchins – way back in the 4th century BC.
A new fully illustrated electronic identification guide, Bountiful Bryozoans, has just been released to help people identify this group of marine creatures in the wild.
Exploring the deepsea

Despite many centuries of maritime exploration, only a fraction of our planet's seafloor has been observed. NIWA Deepsea Scientist Di Tracey tells us what it feels like to probe deep beneath the waves to see what's living on the ocean floor.
