Great story on mapping rivers in shelf seas with ocean gliders in Aotearoa New Zealand. uv-2.com Even made the front cover with TeledyneMarine glider + Mt Taranaki by Fiona Elliott. @niwa_nz Sustainable Seas
Great first PhD paper by Rafa Santana 👏👏👏 Analysis of year-long moorings deployed across New Zealand’s NE Shelf to observe the highly variable boundary current and its interaction with shelf seas @niwa_nz
I usually post about field work but last 12 months have been slow-going. Even today… was supposed to deploy a glider but Welly + COVID + uncertainty = cancelled trip. Sigh. Feels like treading water. Good stuff is happening too, I’ll be a JGR-Oceans editor from July 1 AGU Ocean Sciences
Congratulations to Khushboo Jhugroo on her successful PhD defence today. It’s been a great 4 years of glidering + sciencing!
WRIBO measured salinity in Wellington Harbour lower than 10 psu- it’s usually around 32 psu - after all that rain on the weekend. That’s fresh! River plume will keep heading out to Cook Strait + beyond providing connectivity between our mountains + oceans @niwa_nz Greater Wellington
Bluest ocean I've ever seen! Last Nov 2021 went to Rangitāhua/Kermadec Islands w Expedition Rangatahi. Such a privilege. Ocean glider+ big internal waves! Supports Ngāti Kuri-led research w Auckland Museum + Inkfish Auckland Museum neihana manawatu NIWA, vid by Annika Andresen
Glider deployment #30 underway. Manaia sampling from Bay of Islands to Bay of Plenty in 30 days for MBIE Science smart idea. Ocean glider data + models = realistic ocean forecasting for Aotearoa’s oceans. Jasmin McInerney @niwa_nz MetOcean Solutions
Cyclone vs robot. 120km/h wind gusts vs 1.5m glider. Tomorrow they go head-to-head!🤞ocean glider Manaia will observe rapid upper ocean mixing for Deep South Challenge: Changing with our Climate. How will ocean cooling from cyclones or storms impact Aotearoa’s weather in a changing climate? @niwa_nz NIWA Weather
Come do a summer research project with Alice Della Penna (she/her) Dr Denise Fernandez and me. auckland.ac.nz/en/study/schol…
Disentangling physical-biological oceanographic processes in the Rangitāhua/Kermadec region. PhD project working with me, Alice Della Penna (she/her) + Dr Denise Fernandez starting early 2023. Supporting Ngāti Kuri-led research with Auckland Museum Ngati Kuri Auckland Museum
Back from leading a 3-week RV Tangaroa voyage to Rangitāhua/Kermadecs Islands. It wasn’t always easy but I feel very privileged. Amazing location, great team, new knowledge of this pristine marine ecosystem. Ngāti Kuri-led research with Auckland Museum Ngati Kuri Auckland Museum
Still time to apply for this PhD scholarship. New ocean observations - Nov 2022 - from Rangitāhua to disentangle biophysical processes. Another voyage in June 2023 for successful candidate to gain ocean-going research skills. Alice Della Penna (she/her) Dr Denise Fernandez Ngati Kuri Auckland Museum
Neat modelling + obs assimilation for East Auckland Current. Well done Rafa Santana “in situ subsurface temperature is of utmost importance to correctly simulate the top of the thermocline-one of the most difficult regions to simulate in ocean models” @helensmacdonald @niwa_nz
