Underwater camera technology development: Drop camera/Baited Remote Underwater Video Systems 

The primary focus of AORG camera development team is to create camera systems that can produce high quality imagery of underwater environments. For large-scale deep water applications, AORG has developed an 80 000-lumen ultra-high definition drop camera system easily deployed from a small fishing vessel. This system has been used extensively in the past 2 years, with over 300 deployments in the challenging waters of the Bay of Fundy.

Another area of interest is the development of small, autonomous camera systems that can provide long term monitoring options while capturing high resolution images of the seafloor. The development team is continuously designing and developing lighting solutions and innovative camera housing like the light in-oil and the 360 camera system.

Research Scientist Fisheries and Oceans Canada

Dr. Emmanuel Devred is a research scientist at the Bedford Institute of Oceanography (Fisheries and Oceans Canada) with more than 20 years of experience in the field of radiative transfer, marine optics and satellite remote sensing. His interests include the development of bio-optical algorithms, which relate information on marine constituents (e.g., phytoplankton) to the light field and are applied to data collected by satellite ocean colour sensors to derive information on the marine environment. This information, in turn, can be used to monitor the state of the ocean under climate change, and can provide scientific advice for ocean management and decision-making. His playground covers the three Canadian oceans including coastal and offshore environments.

Using Satellite Oceanography for real-time GIS 

Satellite ocean colour radiometry provides a synoptic view of the coastal and offshore marine environments at a frequency that is unmatched by other observation means. However, its full potential can only be achieved when field data are used to develop and validate algorithms that are applied to this technology to derive information on water properties such as phytoplankton biomass and production, sediment load or water transparency.

Several examples will be presented, emerging from research carried out at the Bedford Institute of Oceanography (BIO), that illustrate the development of bio-optical algorithms and demonstrate the utility of ocean-colour products to monitor the health of our oceans, to quantify changes in the marine ecosystem, and to help in the management of fisheries and protection of our oceans.

These examples include i) the early detection of harmful algal blooms in the Bay of Fundy, a recurrent issue that has severe economical impacts in term of fisheries and tourisms, ii) the discrimination of phytoplankton types to help monitor possible shifts in the marine ecosystem as a result of climate change with potential impacts on fisheries, iii), derivation of near-real time water clarity to infer bathymetry and bottom-type classification, and iv) monitoring of sediment transport by large rivers.

The presentation will also discuss the various sensors that are currently available for ocean colour measurements and the requirement of supplementary oceanography data (e.g., sea surface temperature) to increase the value of ocean colour products.

The Interplay between Knowledge Graphs and Machine Learning

Machine learning algorithms aim to make sense out of noisy data to generate data-driven insights. These algorithms, often called smart algorithms, are first given access to real-world examples of a huge data set, and then are set to detect patterns (or ‘similar data’) in other datasets in order to predict different events. As expected, the algorithms are only as good as the data behind them.

High-quality data can be extracted from knowledge graphs such as from google’s knowledge graph and Wikidata. Knowledge graphs form crucial components of modern web search engines and state-of-the art question answering systems as they provide a semantic structure to the underlying  data, i.e., data becomes a source of information that machines can easily interpret, combine and reuse. In this talk, we will discuss how companies running machine learning applications can use knowledge graphs to fine tune results and increase processing capabilities.

Canadian Healthy Ocean Network – MPA mapping/cartography 

Collaboration between the Canadian Healthy Oceans Network (CHONe), Department of Fisheries and Oceans Canada (DFO) and the Applied Oceans Research Group (AORG) is contributing to deep-sea and marine conservation-related monitoring and management approaches, specifically for the biological communities in the Laurentian Channel Area of Interest (AOI) and St. Anns Bank Marine Protected Area (MPA). Developments and advancements in acoustic survey technologies over the past few decades have allowed marine scientists to match the quality of terrestrial mapping efforts in the marine realm. Among these technologies, multibeam echosounders (MBES) have become widely acknowledged and preferred tools for wide-scale offshore mapping, producing accurate, aerial-like images of the seafloor.

More specifically, MBES backscatter, bathymetry, and bathymetry derived layers such as slope, curvature and aspect can all be used to segment and classify the ocean floor into regions with similar biophysical characteristics. They can also provide baseline data from which thematic maps (substrate maps, benthic habitat maps, species-specific habitat suitability maps) of the seabed environment can be derived. Cartographically visualizing marine environments through seafloor mapping not only helps to improve our understanding of seabed habitats, but also contributes to the facilitation of ocean management, mapping of conservation areas, and to the mitigation of increasing human impacts.

The Sedna Epic Expedition: Bringing the Ocean to Eye Level for Inuit Youth in the Arctic

The multi-year Sedna Epic Expedition is comprised of a volunteer team of women ocean explorers, scientists, photographers, videographers, artists, historians, educators and scuba divers from Canada, the USA and Mexico.

Sedna’s dive and snorkel expeditions to the Arctic (in the summers of 2014, 2016 and 2018) involved bringing the ocean to eye level for Inuit youth, girls and Elders living in remote northern communities. Sedna’s sea women bring the ocean to eye level for Inuit youth, girls and Elders via mobile touch aquariums that temporarily house sea critters and by running workshops to build underwater robots equipped with video-cameras. Taking the concept one step further, Sedna’s sea women equip Inuit girls and Elders with dry suits, masks, fins and snorkels, leading them on snorkel safaris to explore what lies beneath the waves in their own back yards.

Through its unique ocean mentorship program, the Sedna Epic aims to inspire and empower Inuit girls and young women of the Arctic—the next generation of leaders in this matriarchal Indigenous society—who will combat not only climate change but societal change in Canada’s remote northern communities.

Subject to vessel availability and funding, Sedna’s sea women will mount an epic snorkel relay of the Northwest Passage—all 3,000 kilometers of it—during the summer of 2020, conducting oceanographic research and delivering their ocean knowledge mobilization program in Inuit communities along the way.

Using Unmanned Aerial Vehicles for coastal monitoring and surge modeling. 

Through repeat UAV surveys throughout the years 2017 and 2018, we collected high-resolution aerial photography and produced digital elevation models to observe seasonal beach dynamics. Effects of three winter storms were captured by the surveys, showing dramatic change of a gravel barrier ridge on Long (aka Miseners) beach. The storms caused breaching of the gravel ridge separating the beach from the Long Lake, turning the lake into a tidal lagoon, with water levels in the lake varying by up to 1.5 meters.

The intrusion of salt water into the lake threatened fresh water wells and coastal dwellings. Analysis of historical shore profiled, LiDAR and BathyLiDAR data showed that the beach crest has retreated by more than 20 meters since 1980’s. The elevation of the crest was slowly decreasing through this time period, followed by a sharp decrease in the winter of 2018, which was a result of strong storm surge.

A storm surge model was developed and validated using Halifax harbour tidal gauge data and applied to the Long beach. The model estimates wind, wave and barometric setup, and wave run-up based on weather and sea state observations/predictions and on the coastal site configuration (coastal morphology and nearshore bathymetry). The model explains 96% variability in observed hourly water levels. Using high-resolution digital elevation models in surge modeling improved our understanding and capacity to predict the risk of wave run-up, flooding and coastal erosion. The developed model can be used to predict surge effects at other similar gravel beaches.

The Forum is an informal organisation open to all Canadian Organisations  (including non-OGC members) and international OGC members conducting business or research in Canada. Example organisations include, but are not limited to Federal, Provincial, Territorial and Municipal governments, Indigenous Organisations, Academia, and Industry.

The Canada Forum will provide a platform for all stakeholders to increase collaboration with a focus on Canada’s requirements for sharing geospatial data and information, capacity building, innovation, outreach, industry business development, and others. The forum is also intended to provide a venue for the community to improve the level of Canadian influence in the OGC geospatial standards process and related standards partners (e.g. ISO, IHO, GEO, UN-GGIM, W3C, CGSB).

The Canadian Forum intends to inform stakeholders on the objectives of the group in the East, West and North of Canada at a series of geomatics events. Another aspect of the Forum is to identify geospatial sectors where Canada excels so that this expertise can be highlighted globally. The Marine geospatial sector is one such sector so the presentation will also focus on the data standards work being conducted that relates to Ocean data.

He has been contributing to OTN’s mission for the last two and a half years by researching and developing models, visualizations, and analytical tools to display, contextualize and interpret OTN biological and physical oceanographic data using R and Python.

Abstract

Acoustic telemetry is an emergent technology for tracking marine species regionally and globally. Electronic tags attached to animals can log position, depth, and a suite of environmental variables, but because of the scale of the ocean, they only offer a pinpointed snapshot in space and time.

Habitat and migration of these tracked species are not ignorant of the seasonal and long-term changes in global ocean conditions that are currently underway. Oceanographic variables influence both animal behavior and the likelihood of detections. Correlating animal detections with oceanographic variables is key to understanding and improving the analysis of marine species movements. But with this correlation come new challenges of highly variable sampling effort, aggregation of detections within and across dissimilar project designs, and dealing with limited sample sizes in animals tagged/detected compared to larger oceanographic data densities and sampling rates. To improve predictions about animal movement, acoustic receiver detections, and population sizes, detections may be correlated with environmental and/or oceanographic variables/models. Leveraging community-built and maintained geospatial and visualization tools in Python/R we are able to put detections of animal movement into the context of oceanographic variables, while preserving and communicating location and time.

The Ocean Tracking Network (OTN) is a global research network uniting telemetry researchers through equipment and data sharing. Its policy makes tracking data accessible while respecting the intellectual property rights of its collaborators. OTN’s novel approach to aggregating acoustic telemetry data lets tag owners leverage the network of affiliated global acoustic receivers to detect long distance movements of their tagged animals, and to use oceanographic observations from stationary platforms and mobile AUVs to characterize the habitat during the tag detection period. OTN provides a set of geospatial and time series based analysis tools in Python, and works with the Great Lakes Acoustic Telemetry Observation System (GLATOS) to provide a similar set of tools in R.

Abstract

Environmental big data and nonlinear systems with high output rate: persistent challenges and novel solutions

Valuable environmental big data are often associated with major challenges regarding their appropriate handling. Moreover, their effective interpretation and their integration in evolving patterns with strong potential for application raise barriers that are even more difficult to overcome. This presentation argues that for challenges of such proportions, while a methodological arsenal focusing on aspects of fast handling of large amounts of environmental data of a wide diversity is beneficial, it is insufficient and sometimes inadequate. The effectiveness of efforts related to environmental big data can be notably enhanced by a comprehensive and suitably targeted assessment of the dynamic system characteristics to which the acquired data are associated. In the case of complex dynamic systems, understanding the nature of the system and monitoring its spatio-temporal change should be seen as more than an optional set of operations.

Considered in isolation, in-depth system-identifying operations can be relatively expensive in terms of time and computing resources, but they may provide insights capable of considerably improving the performance of the tools to be subsequently applied to the data. Not only can the processing time be slashed significantly, and not only can proper resources be more realistically allocated to each task: new, initially unforeseen value may be identified in the data without any additional acquisition effort. Moreover, most natural systems are complex and nonlinear. Their output is usually non-stationary and often strongly irregular. How can we make sense of their output in order to better understand them, when fast data streaming is added to their non-stationary and wild irregularity?

The paper presented addresses the above-mentioned difficulties with the help of methodologies developed by the author, which build on and incorporate some powerful approaches to nonlinear pattern analysis. A key step in this context is the transformation of time series into transition structures, which can be two-dimensional or multi-dimensional matrices. Properties of the resulting matrices are analyzed using rapid procedures and then followed in time in order to characterize systems with fast streaming output.

The methods are introduced systematically, step by step, and illustrated with practical examples. Key aspects addressed include scaling, universality, the detection of long-range correlations and their possibly spurious nature, as well as multifaceted aspects of pattern change identification. Applications concern renewable energy resources and natural hazards.

Over the last 25 years Dr. Danika van Proosdij has been engaged in understanding how the biophysical processes of coastal ecosystems respond to natural and anthropogenic drivers of change. As a coastal geomorphologist and director of two CFI funded labs:  the Intertidal Coastal Sediment Transport Research Unit and Maritime Provinces Spatial Analysis Research Unit, she merges field studies of sediment transport and hydrodynamics with geomatics and geo-visualizing technologies to assess and enhance the resilience of these systems. This includes coastal vulnerability assessment to climate change impacts and the use of ecosystem based adaptation to manage flooding and erosion hazards in Canada, the Caribbean and Indian Ocean.

Over the last decade she has assisted the provincial government critically assess the vulnerability of their dyke infrastructure to coastal erosion and flooding, and develop best practices for management of dykelands and foreshore marshes that protect them. Her longterm engagement with CB Wetlands Environmental Specialists (CBWES) has facilitated the application of innovative techniques, including 3D hydrodynamic modelling and UAVs, to restore close to 100 Ha of tidal wetland habitat in NS.  She is currently leading $2.4M of federally funded research focused on building resilience to climate change impacts along Canada’s Atlantic coastal using nature-based adaptation strategies.

Abstract

Vulnerability Assessment of Dyke Infrastructure in the Bay of Fundy: Challenges and Opportunities

The purpose of this project was to assess the vulnerability and probability of dyke over topping and/or failure in dykeland areas in Nova Scotia within the Bay of Fundy, to help inform decision making by the NS Department of Agriculture. Analysis was performed using updated surveyed dyke elevations, newly released LiDAR elevations from the Province, and other attribute data within the Dykeland Decision Support Tool (DDST).  Vulnerability to over topping and/or failure was identified as a function of water depth, crest elevation, exposure, foreshore marsh width, platform elevation and form (ramped versus cliffed), and presence or absence of armouring.  Dykes were divided into 25 m segments and attributes assigned per segment using an automated process in ArcGIS 10.5.1.  Based on the analysis, dyke tracks were coded into categories of low to high risk and viewed in conjunction with a companion project identifying assets as risk.  Historical patterns of erosion and progradation over the last 60 years were quantified using AMBUR for the 1671 individual marsh units fronting 240 km of agricultural dykes in the Province.

A robust post analysis accuracy assessment was developed and applied to empirically identify areas where reported rates of coastal change were not in line with known coastal processes and individual transects were adjusted manually as needed.   As seen elsewhere in the region, cyclical patterns of erosion and progradation were observed within each Basin however the impacts of human action on this process (e.g. armouring, engineering, dredging) were evident.  Ecomorphodynamic principles were then applied to identify areas of foreshore marsh that had the greatest or least likelihood of continuing to provide natural forms of coastal defense in the future, and time period over which this would occur.  Areas of high vulnerability were assessed for opportunities of strategic managed realignment of dyke infrastructure.

3-D data collection, analysis and visualization

With the advances in laser scanning, drone-based structure from motion, and the ability to map indoors using SLAM and structure from light, the collection of 3-D point cloud data is becoming common place. The coastal zone consists of the area around the land-sea boundary and is critical to many community’s economic development and prosperity. With issues related to ecological degradation, storm-surge flooding and erosion, the ability to map and monitor the condition of the coastal zone in 3-D is critical.

The coastal zone is a challenging place to map; techniques for mapping the land elevation do not work under water and echo sounding methods for mapping the seabed elevation work well in deep water but are dangerous and expensive in shallow water. The Chiroptera II shallow water topo-bathymetric lidar sensor can collect 3-D seamless elevation and RGB-NIR orthophoto data in coastal or freshwater environments. Drones offer the ability for low-cost repeat topographic surveys, but have challenges related to the high absolute spatial accuracy.

Recent advancements in 3-D collection technology now allow the construction of building interiors that can be merged with lidar and drone-derived point clouds to map structure such as real-estate, commercial, and historic properties. The various 3-D data can then be visualized using the latest mixed and virtual reality systems to better interpret and represent reality.
