Mapping of Marlborough Sounds

Seabed charts of the Marlborough Sounds dating back to the 1940s are set to be overhauled in a state-of-the-art digital mapping project. Information from more than 40,000 hectares of Queen Charlotte Sound and the Tory Channel will help to guide council and science in the future use of the area. The joint project between Marlborough District Council, National Institute of Water and Atmospheric Research and Land Information New Zealand has begun.

Multibeam Echo Sounders Supporting Water Quality

Multibeam Echo Sounders (MBES) are increasingly being used in fresh water environments to support water quality management programs for rivers, lakes and dams as well as asset management for submerged structures such as dam faces, intakes and outfalls. This high resolution mapping is revealing remarkable detail of submerged features providing clients with a baseline data set from which to better understand the capacity of their assets, their value and the impact of run off, erosion and siltat...

DML Supports Tauranga Boys College in Fiji

Tauranga Boys College recently returned from Fiji where they undertook a post cyclone rebuild of the Yamacia Rugby Clubs' youth accommodation block. In one week the team of students, teachers and locals built a new accommodation block for the team with the aid of generous donations from local and New Zealand companies.

DML Staff & friends take on the 2016 Tawharanui Coastal Challenge

The 23km Mid-Monty distance event was held through the Tawharanui Regoinal Park, Auckland and required 'Team DML Loaded' to run, walk, hobble, scramble, wade, climb and crawl their way around some of Auckland's most pristine coast. The course took us east from Campbells Beach through numerous bays across white sand, stones, gravel, boulders and gnarly rocks. Next we were up and over the peninsula through a mixture of native bush trails and grassed tracks which offered awesome panoramic views ...

Surveying Bridges & Super-Structures

Surveying Bridges & Super-Structures Bridges and other structures spanning waterways present challenges when it comes to asset management and maintenance. The structure lifespans are typically measured in decades, with both the surface and subsurface components subject to a number of stresses and strains over long periods of time. Bridges are often subject to tidal flows 24 hours per day. Understanding the extent and nature of any scouring around the main bridge piles, can be key to he...

Ōpōtiki Harbour Development – a clear mandate to develop economic & social wealth

It was pleasing to be present at today's Applicant briefing for the investigation, design and construction of the Ōpōtiki Harbour Development project. Robert Edwards, Chairman of Whakatōhea, is clearly a passionate supporter of the Harbour Development given the benefits it will bring to the community. The estimated R.O.I to the community, by way of new business development and employment was expressed numerically; an impressive ratio in itself. However what is really exciting, is the downs...

Need to inspect submerged infrastructure?

We've been working with mobile laser scanners and our multibeam echo sounders to produce 3D data and images where we combine the data sets from both below and above the waterline. This is an ideal way of inspecting and monitoring submerged infrastructure. Our Senior Surveyor, Declan Stubbing undertook a trial last year to prove this application and achieved some exciting results. Feel free to contact Declan direct to discuss whether this may be of interest in your business. declan@dmlsurveys...

However, DML considers this as mandatory for business sustainability. The operation and knowledge of high end swathe sonars for engineering, port maintenance/development and national charting agencies is a complex business. DML is ensuring its people are staying abreast of advances in sonar capabilities and i...

Coda Echoscope

DML recently had a visit from Coda Octopus, demonstrating their impressive 3D real time imaging sonar, the Echoscope. The echoscope sonar has an 128x128 beam acoustic array which provides over 16,000 data points per return at over 10hz. This means the user can see a real time 3D imaging video in zero visibility subsurface conditions. DML sees the potential for this tool to supplement traditional multibeam bathymetry surveys in hard to access areas such as under large wharfs and structures, a...

The Next Generation

Getting the next generation into hydrography and marine science is close to the hearts of the team at DML. More often than not these disciplines fly under the radar. The House of Science (http://www.houseofscience.org.nz/) at Waikato University's Sulphur Point Marine Lab is supporting local teachers with pragmatic applied science kits for their classrooms, to help stimulate interest in the sciences. Recently DML assisted the House of Science by sponsoring the development of a new resource kit....

Laser Scanning from a Vessel

We recently conducted a trial in Auckland, New Zealand whereby a Terrestrial Laser Scanner was mounted to the roof of our vessel PANDORA II and driven around Westhaven Marina and the Auckland Harbour Bridge. The trial will form the basis of a paper being presented at the Australasian Coasts and Ports 2015 Conference in Auckland in September. The locations for the trial were scanned at a rate of 2000 points per second, the detail of which is not evident in these images. The results exceeded our...

PANDORA II, DML’s new dedicated MBES survey vessel.

The demand for Multibeam Echo Sounder (MBES) surveys is increasing in New Zealand. DML has responded to the demand by recently commissioning a dedicated MBES survey boat. Pandora II is a 7.5m catamaran and incorporates a clever mechanism whereby the sonar transducer is raised and lowered through a moon pool arrangement located between the hulls and operated by a hand winch. Being a catamaran design, the boat is very stable and manoeuvrable and can operate in very shallow water. She is fitted w...
