“…Studies in other regions (Piercy et al 2014, Kaplan et al 2015 have also observed a positive correlation between spectral levels in this band and indicators of ecosystem function. It is intuitive to surmise that greater numbers of acoustically active organisms would create louder biological soundscapes.…”

“…Nondestructively determining whether there is any such relationship may be challenging as snapping shrimp are usually subterranean creatures and are rarely observed above the substrate. Directional acoustic re ceivers may be employed to determine the location of snaps in an area (Ferguson & Cleary 2001, Chitre et al 2012, Kaplan et al 2015, producing estimates of snapping shrimp distribution in a localized area. Re gardless of the process that connects high-frequency sound and the proportion of algal cover, the correlative findings shown here introduce the possibility of an acoustic indicator of algal dominance, and in some situations, of reef degradation.…”

“…Wave energy and tidal or other currents are always minimal throughout the area. Biotic sounds experience small peaks around dawn and dusk but are uniform at other times [11]. These uniform water characteristics are not believed to be a major source of spatial or temporal variability on transmitter detections [4,6,12,13].…”

Baffling telemetry detections can be useful: an acoustic receiver design to monitor organisms along reserve boundaries and ecotones

Background: Many biotelemetry studies seek to detect movement of organisms across reserve boundaries or between adjacent habitat areas. Our objective was to enhance this capability in studies of aquatic organisms that are tagged with acoustic transmitters and tracked by passive data loggers. We installed an experimental shroud on a commercially available telemetry receiver. The shroud was designed to baffle incoming signals from transmitters along one hemisphere of the receiver and therefore more conclusively determine which side of a boundary line that a tagged organism occupies.Results: Range testing of shroud effectiveness was conducted along the border of a marine-protected area in a coral reef ecosystem. A transmitter of the type implanted into reef fish was deployed in various directions, distances, and landscape settings relative to 11 shrouded receivers. There was a significant difference in the detectability of transmissions on the shrouded versus unshrouded side of the receivers. On the unshrouded hemisphere of the receiver, 75-100 % of transmissions within 100 m were detected and maximum effective detection range was ~180 m. On the shrouded hemisphere of the receiver, detections were rare at any distance with a maximum of 12 % of transmissions recorded even as close as 60 m away. Conclusions:The shroud modified the detection area of a standard omni-directional receiver into a hemi-directional receiver better able to detect transboundary presence. The approach is useful for applications that require detection of simple boundary-crossing events using a minimal number of receivers.

“…We will assess biodiversity diversity following new measurements developed for coral reef soundscapes, such as the median difference in daily max and min values (Kaplan et al 2015) and a fish-sound detector/classifier (Kaplan et al 2014). These measures seek to statistically quantify soundscape variability relative to the presence of OSW and changes in overall biodiversity between experimental and control areas.…”

The landscape of applied ocean technology is rapidly changing with forces of innovation emerging from basic ocean science research methodologies as well as onshore high tech sectors. There is a critical need for ocean-related industries to continue to modernize via the adoption of state-of-the-art practices to advance rapidly changing industry objectives, maintain competitiveness, and be careful stewards of the ocean as a common resource. These objectives are of national importance for the dynamic ocean energy sector, and a mechanism by which new and promising technologies can be validated and adopted in an open and benchmarked process is needed. POWER-US seeks to develop Ocean Test Beds as research and development infrastructure capable of driving innovative observations, modeling, and monitoring of the physical, biological, and use characteristics present in offshore wind energy installation areas.The Industry Need: Throughout the second half of the last century, ocean technology advancements ushered in new ocean-related industries and ocean advancements that changed the course of history. Remote and deep water oil and gas exploration and extraction methods, bottom survey methods, global shipping route optimization, ocean storm and weather forecasting, etc. have enabled substantial economic gains. That much of ocean science and engineering today continues to rely on technologies developed in the last century is a testament to the robust nature of our previous development efforts. However, more recent technological innovations in environmental sensing, computing, and automation offer the potential to further revolutionize both existing ocean-related industries such as: energy, mining, transportation and shipping, global trade, adaptation and resiliency, defense and security, salvage, and ocean exploration as well as newly emerging ocean uses.One clear example of the need for rapid adoption of new technology is in the area of offshore wind energy production. As a new energy industry in the U.S., offshore wind shows tremendous potential as a component of the nation's energy future portfolio. However, solid scientific data on the design characteristics as well as consensus on the interactions of a wind farm with the marine environment are critical to reduce risk, advance public acceptance, and evolve the regulatory process. Coupling this with the unique conditions present over the U.S. outer continental shelf in areas slated for development, an acute need exists for creating the physical and organizational infrastructure to rapidly move innovations in site characterization through systematic validation and into industry best practices and/or regulatory requirements. This process requires an open and evolving infrastructure that allows benchmarked data sets to test and evaluate sensors, improved systems modeling, and analysis by neutral, disinterested parties.
