ANTARCTICA NEW ZEALAND NEWS
 

Welcome to the final Science Update for 2018! We hope you have found these newsletters to be an interesting and useful source of Antarctic information. Many thanks to those of you who have contributed items over the past year - please do keep sending us any content you wish to be included.

This month we bring you a 'holiday special' update featuring photos and tales from a few of the scientists who have returned home following their successful season on the ice.


 

SEASON'S GREETINGS FROM ANTARCTICA NEW ZEALAND  

On behalf of those of us in the Christchurch office, our colleagues at Scott Base, members of the Antarctic Science Platform and the Scott Base redevelopment team, we would like to take this opportunity to sincerely thank all of you for your support and efforts throughout the year. A challenging start to the season tested our skills in flexibility and fortitude, but thanks to your ongoing commitment we are now back on track and continuing to support world-class science.

Highlights for this year include being named as the host of the Antarctic Science Platform, a strong kiwi contingent at the Scientific Committee on Antarctic Research conference in Davos, as well as the many exciting scientific discoveries made over the course of the year.

The team at Antarctica New Zealand send warm wishes to you and your family for a very Merry Christmas and a safe and Happy New Year. We look forward to continuing to work closely with you in 2019.

TALES FROM THE ICE


K066 - Natalie Robinson, NIWA
K066 returned from the ice at the end of November with a suite of new observations in the bag: cross-sound transects of snow, ice and sub-ice platelet layer thicknesses; ocean data from all levels beneath the ice, including timeseries of suspended frazil ice; and timelapse imagery of underwater ice growth on ropes, instruments and equipment. The team were joined by Florence Isaacs, a 2018 Antarctica NZ scholarship winner, and by ‘Walter’ the Weddell Seal who took up residence in one of the ocean access holes – both of whom fitted in well!

K083B - Kim Goetz, NIWA

K083B successfully completed the first part of their field season, gathering data from 21 adult female Weddell seals. The 4 person international team commuted by snow machine from Scott Base to access seals located at Tent Island, big and little Razorback Islands, Hutton Cliffs and North Base located at the base of the Erebus glacier tongue.
This project operated under DOC Permit Number: 69331-MAR

K043 - Ken Ryan, Victoria University of Wellington
Team K043 returned home after a successful season investigating the distribution and health of primary producers under the sea ice. The team implemented an under ice hyperspectral camera run on second hand skis which allowed the rig to be towed along a transect 1m wide by 15m long, to determine baseline data of sea ice microbial biomass. A remotely controlled robot was used to aid in the deployment of the hyperspectral camera rig. The team were joined by Michael Bollen, a 2018 Antarctica NZ scholarship winner.

The team were also lucky to receive some special visitors to their camp - of the emperor penguin kind!

K812 - Craig Cary, University of Waikato

K812 completed 8 days of intensive work at Cape Hallett generously hosted by our Korean Polar Research Institute (KOPRI) colleagues.  KOPRI has established a 5 year camp at Hallett to continue their work monitoring the Adélie penguin colony. The camp includes a solar powered hut large enough for 11 researchers to work and live.  Our NZARI-supported work included hyper-spectral imaging of the colony and high productivity moss beds with a new drone, activity assessments of springtails and moss under new active in situ warming chambers, and continued assessment of the impact of the colony on local and regional microbial communities.

K085 - Dan Smale, NIWA

During November 2018, as part of a new NIWA, Antarctica New Zealand & USAP scientific collaboration Mike Kotkamp (NIWA) visited McMurdo station's radiosounding facility to install a standard humidity chamber (SHC) and train their operators on its use.  The SHC is a 100% relative humidity (RH) environment used as an additional ground-check for radiosonde humidity sensors (radiosondes typically only have a 0% RH check).  Constraining the upper limit of humidity values improves the water vapour estimates while decreasing their uncertainty, especially important in dry environments like the atmosphere above Antarctica.  Now, in addition to McMurdo radiosonde data's operational role in forecasting, those same data will be post-processed at the GCOS Reference Upper Air Network (GRUAN) Lead Centre and made available to the scientific community in their value-added format.  A similar SHC has been installed and operating at the NZ MetService's Invercargill site since 2016. The McMurdo sonde data will be the first Antarctic data processed by GRUAN.
