  • Echosounders
    The Pathway A program for regulatory certainty for instream tidal energy projects Report Scientific Echosounder Review for In-Stream Tidal Turbines Principle Investigators Dr. John Horne August 2019 Scientific-grade echosounders are a standard tool in fisheries science and have been used for monitoring the interactions of fish with tidal energy turbines in various high flow environments around the world. Some of the physical features of the Minas Passage present unique challenges in using echosounders for monitoring in this environment (e.g., entrained air and suspended sediment in the water column), but have helped to identify hydroacoustic technologies that are better suited than others for achieving monitoring goals. John Horne’s report and presentation will present a overview of echosounders and associated software that are currently available for monitoring fish in high-flow environments, and identify those that are prime candidates for monitoring tidal energy turbines in the Minas Passage. This project is part of “The Pathway Program” – a joint initiative between the Offshore Energy Research Association of Nova Scotia (OERA) and the Fundy Ocean Research Center for Energy (FORCE) to establish a suite of environmental monitoring technologies that provide regulatory certainty for tidal energy development in Nova Scotia. Final Report: Scientific Echosounder Review for In-Stream Tidal Turbines Prepared for: Offshore Energy Research Association of Nova Scotia Prepared by: John K Horne, University of Washington Service agreement: 190606 Date submitted: August 2019 Objectives: The overall goal of this exercise is to evaluate features and performance of current and future scientific echosounders that could be used for biological monitoring at in-stream tidal turbine sites.

    Appendix VII Final Report: Scientific echosounder review for instream tidal turbines Final Report: Scientific Echosounder Review for In-Stream Tidal Turbines Prepared for: Offshore Energy Research Association of Nova Scotia Prepared by: John K Horne, University of Washington Service agreement: 190606 Date submitted: August 2019 Objectives: The overall goal of this exercise is to evaluate features and performance of current and future scientific echosounders that could be used for biological monitoring at in-stream tidal turbine sites. Specific objectives include: 1. Reviewing literature for desired characteristics of scientific echosounders used in marine renewable energy monitoring applications. 2. Communicating with scientific echosounder manufacturer representatives to confirm current and future performance features of scientific echosounders. 3. Evaluating and reporting findings. Introduction and Overview Environmental monitoring is a required component of Marine Renewable Energy (MRE) licensing and operations throughout the world. Biological monitoring at instream tidal sites is the most challenging of all MRE industry sectors due to challenges associated with sampling. Biological monitoring at MRE sites is constrained by hydrodynamics that limits traditional sampling (i.e. nets) due to high water flow velocities and remote sensing (i.e. active acoustics) that is constrained by entrained air and turbulence. As a result, little historical data are typically available to characterize biological constituents, and the choice, timing, and deployment of monitoring equipment requires additional planning compared to less dynamic environments. The primary challenge when choosing any remote sensing instrument is maximizing the signal to noise data ratio. This generic statement has three relevant components when using active acoustics to monitor aquatic animals at instream tidal sites: near boundary interfaces, target resolution, and target detection (i.e.

  • Ices S Sym Mposiu Um
    ICES SYMPOSIUM MARINE ECOSYSTEM ACCOUSTICS – OBSERVING THE OCEAN INTERIOR IN SUPPORT OF INTEGRATED MANAGEMENT 25-28 MAY 2015 NANTES, FRANCE someacoustics.sciencesconf.org BOOK OF ABSTRACTS We thank the following commercial sponsors for their support: Symposium Overview Marine ecosystem acoustics is an approach that utilizes acoustics as the primary tool for understanding, assessing, and monitoring marine ecosystems. The approach holds the potential of becoming a principal contributor to operational Ecosystem Based Management (EBM). It is part of the strategy to move towards integrated management within ICES, but also elsewhere. The potential of marine ecosystem acoustics cannot be realized without systematic cross disciplinary interactions and cooperation within fields such as fisheries acoustics, physics, engineering, biology, oceanography, ecology, and ecosystem modelling. The ability of acoustics to resolve ecosystem processes at the spatio-temporal scales at which they occur fosters improved and new ecosystem understanding, such as quantification of physical forcing and biological responses, and patterns in prey-predator distribution and interactions, which are a prerequisite for EBM. The primary aim of this symposium is to bring together scientists and ideas from various fields to facilitate and catalyze interdisciplinary interactions with acoustics as the central tool to further the development of marine ecosystem acoustics. The Symposium will review and discuss recent developments in acoustic methods and technologies used to characterize and manage marine and freshwater ecosystems. Particular emphasis will be placed on technologies used to measure diverse aspects of the aquatic environment, techniques for data analysis, and the integration of multiple data sets to elucidate functional ecological relationships and processes. Contemporary challenges and future directions of these objectives will be identified.

Yet, the SSLs taxonomic composition remains largely unknown. To improve our comprehension of SSLs, a dedicated study was conducted in Northern Bay of Biscay (France) using broadband acoustic. Four broadband EK80 (i.e. 70, 120, 200 and 333 kHz nominal frequencies) and two narrowband EK60 (i.e. 18 and 38 kHz) echosounders were used to obtain the frequency spectra of SSLs in two contrasted zones. Groundtruthing data were collected by deploying plankton and micronekton nets and in situ video in the SSLs. Measured frequency spectra were compared to forward modeled spectra derived from groundtruthing data to identify organisms contributing to the observed SSLs. The results showed that SSLs were dominated by resonant Gas Bearing organisms, siphonophores and juvenile fishes, especially in the lower range of frequencies (< 90 kHz).

With four million echoes at each frequency, this data set permitted thorough explorations of some practical considerations that influence every acoustic seabed classification. Our unsupervised classification involved an objective determination of the optimal number of classes for each of the pre-classification methods we explored, allowing useful comparisons among methods. Stacking, one of the pre-classification steps, is the process of averaging sequential echoes to allow sediment information to express itself in spite of ping-to-ping variability. With stacks of fifty pings, feature spaces had more detail and better defined clusters, thus more classes in unsupervised classification, compared to stacks of five pings. Classification by echo shape requires changing the sampling rate to compensate for depth changes. While effective, this changes the apparent roughness and the amount of detail submitted to the feature-generating algorithms.

  • Sounding out Life in the Deep Using Acoustic Data from Ships of Opportunity
    www.nature.com/scientificdata OPeN Sounding out life in the deep DAtA DeScriptOr using acoustic data from ships of opportunity K. Haris ✉, Rudy J. Kloser , Tim E. Ryan , Ryan A. Downie, Gordon Keith & Amy W. Nau Shedding light on the distribution and ecosystem function of mesopelagic communities in the twilight zone (~200–1000 m depth) of global oceans can bridge the gap in estimates of species biomass, trophic linkages, and carbon sequestration role. Ocean basin-scale bioacoustic data from ships of opportunity programs are increasingly improving this situation by providing spatio-temporal calibrated acoustic snapshots of mesopelagic communities that can mutually complement established global ecosystem, carbon, and biogeochemical models. This data descriptor provides an overview of such bioacoustic data from Australia’s Integrated Marine Observing System (IMOS) Ships of Opportunity (SOOP) Bioacoustics sub-Facility. Until 30 September 2020, more than 600,000 km of data from 22 platforms were processed and made available to a publicly accessible Australian Ocean Data Network (AODN) Portal. Approximately 67% of total data holdings were collected by 13 commercial fishing vessels, fostering collaborations between researchers and ocean industry. IMOS Bioacoustics sub-Facility offers the prospect of acquiring new data, improved insights, and delving into new research challenges for investigating status and trend of mesopelagic ecosystems. Background & Summary Since 2010, as a part of existing ocean industry collaboration, Australia’s Integrated Marine Observing System (IMOS) Ships of Opportunity (SOOP) Bioacoustics sub-Facility (here onwards IMOS Bioacoustics sub-Facility) has been collecting opportunistic, supervised, and unsupervised active bioacoustic data from different plat- forms including commercial fishing and research vessels transiting ocean basins1 (Fig.

  • Improving Acoustic Surveys by Combining Fisheries and Ground Discrimination Acoustics. ICES CM 2002/K10
    Not to be cited without prior reference to the authors ICES CM2002/K:10 Improving acoustic surveys by combining fisheries and ground discrimination acoustics Steven Mackinson, Steven Freeman, Roger Flatt and Bill Meadows The Centre for Environment, Fisheries and Aquaculture Science, Lowestoft Laboratory, Pakefield Road, Lowestoft, Suffolk, NR33 0HT, UK. Phone: +44 (0)1502 524295. Fax: ++ 44 (0)1502 524511. e-mail: [email protected] Abstract Field surveys are notoriously costly. Whilst continuous acoustic surveys provide good value in terms of their data richness and spatial coverage when compared to point sample surveys (e.g. trawls, dredges, grabs), there is scope to improve survey methods and provide value added data. We present technical details and an example application of an approach that maximises survey efficiency and data richness through the integrated use of two acoustic tools; a fisheries echosounder and ground discrimination system. Simultaneous, integrated operation of both systems provides a more cost- effective use of survey time by eliminating the need to conduct independent coverage. The scientific benefit is that the approach removes the temporal confounding of spatial data that results when trying to compare data from two independent surveys. i.e. it enables fish to be placed with their habitat by linking information about seafloor composition directly with fisheries data. Key words: acoustic surveys, cost-effective, integrated technology, spatial distribution Introduction The ability of fisheries and ground discrimination acoustic surveys to offer continuous, high resolution observations through the water column, provides a spatial and temporal data richness that cannot be achieved by point sampling methods such as trawls, grabs and dredges.
