    This Webinar which was delivered by Dr Joshu Mountjoy, who is a NIWA Scientist / Marine Geologist - Ocean Geology was focused on Survey technologies used to find the aquifer offshore south Canterbury. In this Webinar, Joshu has explained the offshore survey campaign to find and map the aquifer.

    This is a unique survey as our AHS members are usually involved in surveys for oil/gas/wind farms or dredging/aggregates.

    This Webinar was delivered on 14 May 2020 13:00 - 13:30 (UTC+12:00).

    The recording are now available through link below.

    This well attended webinar was Cory Brooks (Unique Group) on remote control boat surveying under structures and the ixBlue ASV. This was followed by Emily Tidey (Hydrographic lecturer - Otago Uni) talking on surveying / geology on a NZ sub antarctic island.

    Last year a research team of staff and students at the University of Otago's School of Surveying sought the views of hydrographers to use in an investigation considering the development of the profession in New Zealand as part of a larger project titled: Tuia: 250 years of navigation, map making and belonging. Tuia 250 commemorated the first meetings of Māori and European at the time of Captain Cook's first visit to New Zealand in 1769.

    We are so grateful for all the thoughtful and detailed responses we received, which totalled over 50 (we had thought >20 would be a good result!), and thank you and your colleagues for your valuable contributions.

    In 2019, as we worked on the fantastic questionnaire input you gave us, we shared interim findings with audiences at the Survey+Spatial NZ (formerly NZIS) conference, the NZR AHS seminar, at a School of Surveying seminar, with students from Te Tumu (School of Māori, Pacific and Indigenous Studies) at Otago University and at the NZ Coastal Society conference.

    The final results of our investigations have now been published in  the article 'Cook: Our Professional Ancestor' in the recent Special Edition of New Zealand Surveyor. We also have another publication in this edition discussing the evolution of hydrographic technology and charting:

    1) Cook: Our Professional Ancestor [page 79]

    2) Charting Our History [page 131]

    To read these, New Zealand Surveyor Special Edition (Dec 2019, no. 305) can be downloaded at: [direct to the Special Edition] [to all online versions of this journal]

    We encourage you to share our articles widely with the hydrographic community – we hope they will be especially interesting to those who responded so positively to our questionnaire.

    We also wish to acknowledge the support of:

    1) The Australasian Hydrographic Society (AHS) who funded our students. This enabled the running of online survey, gave our students a day on the water using multibeam, enabled our students to present their work at the S+SNZ conference and will facilitate the proper presentation of the charts donated in 2) below.

    2) Ron Tyson (of NZ Ocean Technologies Ltd) for his generous donation of three 1700's charts which formed the focal points for our second published article.

    On 27 August, the Australia-New Zealand Emergency Management Committee (ANZEMC) endorsed the National Framework for Flood Warning Infrastructure and the Flood Warning Infrastructure Standard developed by the National Flood Warning Infrastructure Working Group (the Working Group). The Framework provides guidance for future flood warning infrastructure planning and investment, based on jurisdictional analyses of their flood warning infrastructure. The Standard presents non-mandatory industry-recommended performance requirements for the design, development and monitoring of fit-for-purpose flood warning infrastructure. These initiatives will guide future flood warning infrastructure investments in an integrated and cost-efficient manner, to enhance flood warnings to the community. This marks the successful conclusion of the time-limited Working Group and is testimony to the collaborative nature of the Working Group and the hard work of all involved.

    Following Munro (2011) recommendations, ANZEMC established a Bureau of Meteorology Hazards Services Taskforce (the Taskforce) in October 2013. The Taskforce reported to ANZEMC in May 2015 and recommended the formation of the Working Group. The Working Group was established in 2016 to address the limitations and inconsistencies of flood infrastructure and standards across Australia. The Working Group involved extensive collaboration and inter-agency cooperation to standardise national flood warning services and infrastructure; an ambitious undertaking given the wide variety of climates, jurisdictions, and agencies involved. The Working Group was a time-limited project, working to deliver a Flood Warning Infrastructure Standard, Infrastructure reports for each jurisdiction, and a National Framework for Flood Warning Infrastructure by 2019. The Working Group produced these deliverables within the specified timeframe.

    Chairs of the ANZEMC

    Collaboration was key to the success of the Working Group. In accordance with the Total Flood Warning System, flood warnings in Australia are provided via a partnership involving all levels of government: Commonwealth, State, Territory and local. While the Bureau of Meteorology has the responsibility for the provision of forecasting and warning services for riverine flooding in all states and territories (with limited exceptions), the prime responsibility for flash flood warnings lies with states and territories in partnership with local government. However, the Bureau provides forecasts and warnings for severe weather conditions and potential heavy rainfall conducive to flash flooding. Given the already inter-dependent nature of these relationships, the Working Group demonstrated the significance of a cooperative spirit to improve the preparedness and safety of the community.

    This year, the Hydrography Professional Stream (HPS) ran a successful one-day event as part of the annual NZ Institute of Surveyors (NZIS) Conference. It was supported by the NZIS organising committee and representatives from the New Zealand hydrographic industry.

    Three university students were generously sponsored by the Australasian Hydrographic Society (AHS) and the New Zealand Region of the AHS and to attend and report on the day.

    Please enjoy reading the students excellent report from the event, from page 21...

    Some of the presenters have allowed their presentations to be made public so please contact Gary Chisholm (NZR, ) if you would like to view them.
