Abstract

The Marine Supply Base channel in Darwin Harbour, Northern Territory Australia provides access to berthing and loading at East Arm wharf for vessels that support the offshore energy industry.

Sedimentation in the channel due to complex currents in the area is reducing navigational efficiency and safety.

A combination of multi-beam echo sounder, utilising an Odom MB1 and Acoustic Doppler Current Profiler, using a network of TRDI Workshorse and Sentinel V, surveys were conducted over a 12 month period encompassing both dry and wet seasons. The MBES surveys mapped the extent of the MSB channel and the East Arm sandbar adjacent to the channel. Tidal current patterns determined from the ADCP surveys show that tidal currents in the area are highly variable and are stronger in the ebb tide direction except at the entrance to the navigation channel. Tidal current are more variable in the flood tide direction at all remaining sites along the channel. The strength and direction of the tidal currents indicate that sediment movement is along the channel toward the deeper seaward navigation channel.

Fine sediments have deposited in the MSB berthing area slightly reducing the volume of the berthing pocket and also depositing toward the end of the channel. An annual sediment deposition rate of 100 mm over the berth area was determined via observations and modelling.

Non-cohesive sand transport modelling, configured using data from the MBES and ADCP surveys, has indicated slow movement of the sandbar in a dominantly south west direction at between 100 – 200 mm per month. Fine sediment modelling indicates deposition in the MSB berth area of 20 – 50 mm/year under average conditions.

Modelling indicates that if the MSB channel was realigned to be straighter the current directions would be more regular assisting navigation. Sediment accumulation would not present a major issue if the majority of the East Arm sandbar was dredged.

Perspectives on the State of Ocean Science

Tue, 14 Nov 2017 09:51:10 GMT

Keynote presentation by Margaret Leinen

The value and role of ocean science and innovation increasingly has been the focus of both international and domestic forums on climate science, sustainability, and defense. Now in its second century of exploration and research, UC San Diego's Scripps Institution of Oceanography is rising to meet new challenges to understand and protect the planet, through interdisciplinary and cross-sector collaborations and a continued focus on developing innovative technology to observe the planet.

Scripps shares its science at international forums such as the United Nations ocean and climate conferences to advise, contextualize and strengthen the efforts of nations, NGO's and policymakers that set and meet standards for sustainable use of the oceans. The United States Navy is also in the midst of assessing the global state of ocean science and technology via Task Force Ocean, and has engaged US academic institutions including Scripps to ensure cutting-edge ocean science is applied to its oceanographic infrastructure, technologies, and technical workforce so that the Navy maintains its global competitive advantage.

In her keynote, Dr. Margaret Leinen will describe these international forums, Scripps role, how Scripps scientists are innovating to meet these global demands in ocean science and technology, and the state-of-the-art research facilities, centers, and education that will shape the future of ocean and climate science.

The Next Great Odyssey of Human Endeavour Exploring the Deep Ocean

Thu, 09 Nov 2017 14:55:25 GMT

Keynote presentation by Oliver Steeds

Humankind is poised to make the next giant leap – into the deep ocean. We now have the technology available to us to discover more of our planet in the next 10 years than we have in the last 100,000.
Throughout human history, exploration has always driven our progress. Lief Ericson's journey to North America (1001 AD), the discovery of the New World (1490s), Magellan's first circumnavigation (1519) and space exploration (1957-) have all pushed back the frontiers of our knowledge, unlocking immense opportunity and changing our relationship to our planet and ourselves.
But since 1969, we've been looking up when we should have been looking down. The most important part of our planet, the deep ocean, remains the least known part of our planet.
The ocean is the heart of our planet. It's 99% of the planet's biosphere[1], regulates our atmosphere and climate and produces 50% of the oxygen we breath[2]. It captures heat and carbon dioxide which dramatically reduces global warming and provides a primary source of protein for 3 billion people[3]. The ocean is everybody's business. How it changes affects us all. The problem is that we don't know how the deep ocean functions, how healthy it is, how resilient it is and how the development of a sustainable blue economy can drive our growth.
The ocean remains the last great unknown frontier on our planet. We've only biologically sampled 0.0001%[4] and mapped an area equivalent the size of Tasmania to the same kind of detail that we have mapped the entire orbs of the Moon and Mars[5].
From Autonomous Underwater Vehicles (AUVs) to Remotely Operated Vehicles (ROVs), from seabed mapping systems and chemical sensors to the initial library of DNA sequences of marine animals, technological developments now unlock extraordinary new research capabilities. We now have the ability to discover more of our planet in the next 10 years than the last 100,000 of human history.
New areas of economic activity such as renewable energy and marine mining are on the horizon. Millions of new species are to be discovered that can propel human medicine. Resources to be unearthed that will drive our sustainable economic development. Even the origins of life on Planet Earth are to be found.
To engage the world in our all of our work, we should be looking to the space community to learn how to improve our story-telling – engaging our audiences with stories that are positive, forward looking and about a brighter future; that are Mission based and trigger the imagination, communicating danger and building on narratives of exceptionalism, patriotism, exploration and the collective human achievement.
Together, as an industry, we are already leading the exploration of the deep ocean, the last, great unknown frontier on Planet Earth.
The Apollo Missions, polar exploration, Jacques Cousteau's adventures, even Felix Baumgartner's space jump captivated the world with their human drama, battles against adversity, and above all, the unknown. We need the unknown. It is the sense of mystery that gives us imagination and makes us human. Our work is the next positive epic story of human endeavor that can inspire humanity.

Mapping and measuring eelgrass beds with an MB1 sonar

Fri, 29 Jan 2016 09:24:08 GMT

This presentation was given at the Teledyne Marine Technology Workshop in San Diego 2015 by Ashley Norton from Center for Coastal and Ocean Mapping

Eelgrass plays many important roles in temperate coastal ecosystems, including as habitat for many species, and as a bio-indicator for water quality in many areas.

The deepest edges of eelgrass beds are considered more vulnerable to water quality issues because of the pre-existing light limitation with increasing depth due to natural light attenuation. However, the deep edges of beds are also often the most difficult to delineate with satellite and aerial imagery often used for large-scale seagrass mapping programs. We are developing a methodology to characterize the depth limit (‘deep edge’), percent cover and canopy height of eelgrass beds at high resolution (~1 m) using water column acoustic backscatter data from an MB1 multi-beam echo-sounder.

An automated data processing workflow is being developed that will use a combination of digital signal and image-processing techniques, including techniques originally developed for medical ultrasound imagery. These data can provide georeferenced acoustic imagery and depth information needed to document the location, structure, and spatial heterogeneity of eelgrass beds, with more spatial coverage than existing acoustic tools that mostly utilize single-beam echosounders.

Water column data were collected over beds at 3 locations in the estuary in the summer of 2014, and preliminary data analysis shows that eelgrass patches as small as 1m2 and as short as 20 cm are detectable. Data was also collected concurrently in the summer of 2015, and they include1) ground-truth data from drop camera imagery and field surveys; 2) aerial surveys; and 3) acoustic backscatter data. The ability to process multi-beam water column data for eelgrass characterization may provide a new data source and tool for ecologists and managers interested in eelgrass distribution and characterization, as well as bathymetric information used for charting depths.

Dual Head Multibeam bathymetry mapping riverbed structures and morphologies...

Fri, 13 Nov 2015 12:55:08 GMT

Along the years, Rural Tech Company has realized a series of surveys of all kind in the Amazon region, especially in Tapajós River. One of the areas that has been studied since 2006 is São Luís do Tapajós in Pará state, near Itaituba city. There, is going to be built one of the five biggest Brazilian hydropowers on terms of energy generation. Current studies, already at an advanced level, include a multibeam survey of about 30 square quilometers. Mapping with a Teledyne Odom MB1 Dual Head (phase and amplitude bottom detection bathymetry), all the riverbed structures and morphologies were well defined, allowing, this way, a great amount of information to be extracted, extremely important for that involved on the hydropower construction study. On the other hand, the contractors could plan their projects with the best benefit-cost ratio, taking advantage of the natural features mapped with the bathymetry.

The benefits of online analysis of sound speed profiles during data acquisition

Mon, 06 Jan 2014 15:35:04 GMT

By Hydrographic surveyor - Morten Sølvsteen, Danish Geodata Agency

Presentation outline

The two major uses of the ”skeleton”

1) Line planning
Line planning for more efficient surveys.

2) On-line analysis of sound speed profiles during data acquisition
A method for analyzing overlapping areas in multibeam echosounder surveys is introduced. The method requires that the velocity of sound at the transducer is monitored during the survey.

The method applies the principle of least squares to determine the vertical offset and the bias of the swaths caused by insufficient knowledge of the velocity of sound in the water column below the transducer.

This presentation was given at the Teledyne RESON Underwater Technology Seminar in Copenhagen 2013.
