Passive acoustic monitoring on a SV3 Wave Glider for fish spawning aggregation detection and characterization
Date: April 24, 2018
Time: 12:00 PM ET
Presenter: Laurent Cherubin, FAU’s Harbor Branch Oceanographic Institute
Many commercially important reef fishes in the Caribbean and southeast US have been overfished to the point that some species, like the Nassau grouper, is considered threatened and on the endangered species list. Mature adults of some species gather in large numbers every year for two to three months at specific locations to spawn.
Once located, the spawning aggregations become an easy target that can be reduced until it can no longer be formed. Most grouper and snapper spawning aggregations in the region have been extirpated and the few that have been documented are vulnerable unless protection can be enacted.
We have developed and demonstrated a novel, autonomous approach to conduct fishery independent surveys in order to search and discover unreported aggregations by mapping the underwater acoustic landscape using an unmanned platform in areas that surround currently known spawning aggregations during the spawning season.
While passive acoustic methods have previously been used for fisheries management and stock assessment, the platforms and algorithms are not currently mature enough to allow for advanced autonomy, drastically limiting the spatial and temporal range, and resulting in considerable operational costs.
In addition to discovering previously unknown spawning sites, the development of novel algorithms, and passive acoustic and environmental sensor systems enables monitoring along with automated detection, classification and surveillance of fish vocalizations.
As well as providing significantly finer scale detection with low latency, this innovative approach also enables greater on-board intelligence and autonomy; reduced launch/recovery and satellite data cost thus further reducing the overall operational costs, while enhancing performance for ocean monitoring missions.

Next Generation SECOORA Data Portal (v2.5)
Stacey Buckelew and Brian Stone, Axiom Data Science
Recorded: February 27, 2018
Building on many years of stakeholder feedback, SECOORA and its technical partner, Axiom Data Science, have been working on a significant overhaul to the SECOORA Data Portal. The updated portal is currently available in beta version (v2.5) to give users access to new features and a revamped design to get more out of the SECOORA data services. The new portal exists on a platform that is more responsive to long time series observations, and has been updated with more advanced discovery and sharing capabilities. The portal offers sophisticated charting abilities, including comparisons between data sources, binning by time, and plotting of climatologies and anomalies. Users can create custom compilations of sensor and model outputs, which can be shared to spotlight environmental events or geographic locations. Ocean profiling sensors, such as gliders, have been enhanced to display depth charts, interpolation via kriging, and 4D interactive charts.
Feedback from test users on the new interface will be integrated into the final, operational version that is expected to replace the current one in April 2018. With these new features, the SECOORA Data Portal will serve as a more powerful tool for users to explore relationships and trends in the physical, chemical, and biological data collected from the waters surrounding the southeast coastal region.
West Florida Shelf and Tampa Bay Responses to Hurricane Irma: What Happened and Why
Dr. Robert Weisberg, University of South Florida College of Marine Science
Recorded: February 13, 2018
Hurricane Irma impacted the west Florida continental shelf (WFS) as it transited the State of Florida from September 10-12, 2017, first making landfall at Cudjoe Key and then again at Naples, as a Category 2 hurricane. The WFS response to Irma is analyzed using a combination of in situ observations and numerical circulation models. The observations include water column velocity, sea surface temperature, winds and sea level. The models are: 1) the West Florida Coastal Ocean Model (WFCOM) that downscales from the deep Gulf of Mexico, across the shelf and into the estuaries by nesting the unstructured grid FVCOM in the Gulf of Mexico HYCOM and 2) the Tampa Bay Coastal Ocean Model (TBCOM) that provides much higher resolution for the Tampa Bay vicinity (Tampa Bay, Sarasota Bay, the Intracoastal Waterway and all of the inlets connecting these with the Gulf of Mexico) by nesting FVCOM in WFCOM.
Both the observations and the model simulations revealed strong upwelling and vertical mixing followed by a downwelling as the storm passed by. This was accompanied by a rapid drop in sea surface temperature by about 4 degrees C and large decreases in sea level with negative surges causing drying in the Florida Bay, Charlotte Harbor, Tampa Bay estuaries and the Big Bend region. The transport and exchange of water between the shelf and the estuaries and between the shelf and the Florida Keys reef track during the hurricane have important ecosystem and sediment transport implications, including an inlet breach that occurred at the Pinellas Co. Shell Key preserve.
Recording Water Levels Through Citizen Science Reporting
Christine Buckel, National Oceanic and Atmospheric Administration’s National Centers for Coastal Ocean Science
Recorded: December 19, 2017
National Oceanic and Atmospheric Administration (NOAA) in partnership with the University of North Carolina, Institute of Marine Sciences, has developed a water level reporting application. The application collects and aggregates reports of observed water levels submitted through citizen scientists. These contributions are photographs with locations and a few simple details that will help weather predictors, scientists, and the public to better visualize and understand changing water levels. This application can be used globally to document high water levels at the coast, such as king tide events, but also far inland, such as snow melt or heavy rainfall events.
Various state and federal partners are currently using water level reports and photographs as communication and model validation tools. Explore the web-based application: What’s your water level? Or log a report from your mobile device.

Web cameras are transforming how environmental monitoring is conducted. Video data is being used for applications related to transportation and commerce, preparedness and risk reduction, and stewardship of coastal resources.
The NOS Web Camera Applications Testbed (WebCAT) is a one year project that is installing web cameras in five locations for various purposes – counting right whales, spotting rip currents, validating wave run up models, understanding human use of natural resources and more. This unique project is a public-private partnership leveraging the expertise and capabilities of private, nonprofit and public sectors.
SECOORA Marine Weather Portal
Jennifer Dorton (SECOORA) and Charlton Galvarino (Second Creek Consulting, LLC)
Recorded: October 24, 2017
Southeast Coastal Ocean Observing Regional Association (SECOORA) members have worked together since 2007 to develop and continuously improve the Marine Weather Portal (MWP). The MWP aggregates data provided by the NOAA National Data Buoy Center, National Weather Service (NWS), National Estuarine Research Reserves, IOOS Regional Associations, and other sources into a map-based product specifically developed for the marine community.
The MWP was developed by meteorologists, web designers, data managers, and outreach personnel with the University of North Carolina Wilmington, University of South Carolina, Second Creek Consulting LLC, and NWS offices in coastal states across the Southeast and Gulf of Mexico. The MWP is currently used to disseminate standardized, consolidated marine information for the SECOORA and Gulf of Mexico Ocean Observing System regions. Explore the portal: http://mwp.secoora.org.
A year and A Hurricane Apart: Nutrient Loading in the St. Lucie Estuary in the Summers of 2016 and 2017
Dr. Ian Walsh, Director of Science and Senior Oceanographer, Sea-Bird Scientific
Recorded: October 3, 2017
The recent history St. Lucie Estuary has included a devastating harmful algal bloom crisis in 2016 and the passage of Hurricane Irma in 2017. SECOORA member Florida Atlantic University broadcasts real time data from the estuary through the Indian River Lagoon Observatory Network of Environmental Sensors (IRLON). The IRLON network includes nutrient and biogeochemical sensors that provide data on the response of the base of the food chain to the mixing and flows of water in the estuary. This presentation will provide a perspective on how the sources of nutrients and high flow events change the environment in the estuary.
Predicting Marine Physical-Biogeochemical Variability in the Gulf of Mexico and Southeastern U.S. Shelf Seas
Dr. Ruoying He, Distinguished Professor of North Carolina State University
Recorded: September 6, 2017
An integrated marine environment prediction system is developed and used to investigate marine physical-biogeochemical variability in the Gulf of Mexico and southeastern U.S. shelf seas. Such variability stem from variations in the shelf circulation, boundary current dynamics, impacts of severe weather forcing, as well as growing population and associated land use practices on transport of carbon and nutrients within terrestrial systems and their delivery to the coastal ocean. We will report our efforts in evaluating the performance of the coupled modeling system via extensive model and data comparisons, as well as findings from a suite of case studies.

The SECOORA Data Portal has over 4,000 datasets that are accessible. Use the to tool explore, download and visualize ocean and coastal data and models in the Southeastern U.S.
The SECOORA Data Catalog contains searchable, downloadable data from all SECOORA-funded observational and modeling assets that include coastal and offshore stations (atmospheric and oceanographic data), IOOS Priority High Frequency Radar Stations, regional and sub-regional coastal circulation, water quality and fisheries habitat models. The catalog also aggregates data from federal and non-federal real-time and non-real time coastal ocean datasets (in-situ, gliders, profilers, drifters, satellite and models) in the SECOORA region.
Coastal Ocean Circulation Influences on Matters of Societal Concern
Dr. Bob Weisberg, University of South Florida College of Marine Science
Recorded: February 28, 2017
The coastal ocean, defined as the continental shelf and the estuaries, is where society meets the sea. It is where bathing and boating abound, where major recreational and commercial fisheries are situated along with maritime commerce hubs, where harmful algal blooms occur, fossil fuels are tapped and alternative energy sources are considered for exploitation, and where tourists and residents simply go to relax. In essence, the coastal ocean is the epicenter for maritime ecosystems services. Managing all of these coastal ocean utilizations, some competitive with one another, and planning for future, sustainable uses, requires the ability to describe the state of the coastal ocean and to predict the effects that may ensue from either naturally occurring or human-induced influences. The state of the coastal ocean is largely determined by the ocean circulation. The circulation is what unites nutrients with light, fueling primary productivity, what determines the water properties in which fish and other organisms reside and what controls the movement of larvae between spawning and settlement regions. The circulation also determines the movement of harmful substances spilled into the sea and the conduct of search and rescue operations. Applications for red tide, gag grouper recruitment and the transport of Deepwater Horizon oil to northern Gulf of Mexico beaches will be discussed.
