Hurricane Matthew Captured by LOBO (Land/Ocean Biogeochemical Observatory)

Graph animation of effects of Hurricaine Matthew.
The above graph highlights the landing of Hurricane Matthew at Jensen Beach. The beach is part of the Indian River Lagoon, which has ten Land/Ocean Biogeochemical Observatories deployed by Florida Atlantic University (FAU).

Hurricane Matthew did not make landfall in Florida, but heavy rainfall on the east coast of the state impacted Florida estuaries. The Indian River Lagoon Observatory (IRLO) monitored the passage of the storm, demonstrating the rapid changes in water quality parameters that occur when large and rare events such as hurricanes disturb estuaries. Most of the effect of hurricanes on estuaries is through the extreme flow of fresh water carrying runoff from the surrounding land, scouring the bottom in the channels and re-depositing sediments in flooded areas.

WE ARE HIRING
 

 

The Indian River Lagoon Observatory Network of Environmental Sensors (IRLON) consists of Sea-Bird Scientific Land/Ocean Biogeochemical Observatory (LOBO) units and weather sensors to provide real-time, high-accuracy, and high-resolution water quality/weather data through an interactive website. IRLON is based at Florida Atlantic University (FAU) Harbor Branch in Fort Pierce, Florida, providing continuous data on the IRL's plants, animals, and environment, and how natural and human-induced stressors impact them.

Hurricane Matthew passed to the east of the Indian River Lagoon on October 7, 2016. The hurricane's approach was recorded in the rapid increase in wind and rainfall (see charts above). The turbidity sensor, which measures the amount of light scattered from particles in the water, showed that the particle load increased as the wind and rainfall increased. While the rainfall dropped rapidly after the passage of the storm, the turbidity decreased more slowly, with significant peaks twelve and twenty-four hours after the peak of the storm. Particle loads increase in the water column generally from three sources: plant growth in the water, injections of particles from runoff, and re-suspension of sediments from the bottom. The turbidity signal seen from the storm is a combination of the runoff and re-suspension, as the time to generate a bloom was too short and the chlorophyll signal decreased as the storm water filled the lagoon.

Given the large amount of sediment and runoff particulates mobilized by the storm, it is likely that effects of Matthew on the lagoon will last much longer than the changes observed in the water column, as the sediment scoured and re-deposited within the lagoon has changed the benthic environment.

Tech Tip: Removing Barnacles

The ocean is full of amazing creatures, but it's not so amazing when they are found clinging to your oceanographic instruments. Biofouling is a common occurrence during extended deployments, and biological growth such as barnacles or algae must be removed before instruments are redeployed or serviced. To clean biofouled instruments, Sea-Bird recommends wrapping your encrusted instrument in an old t-shirt or towel soaked in a dilute vinegar solution (one part white vinegar to two parts water) for 20 minutes to 6 hours depending on the extent of the fouling. Do not soak the instrument in the solution. Then use a plastic putty knife, which can be purchased at your local hardware store, to gently scrape the accumulated wildlife off your instrument. Take particular care around the more delicate conductivity cells and optical sensor faces. Rinse with freshwater afterward and your newly clean instrument is ready to be deployed again.

To avoid some of this hassle, try wrapping the body of our instrument in plastic or copper tape, which can then just be peeled off after the deployment.

Kim Martini
Senior Oceanographer

Kim graduated from the University of Washington in 2010 with a Ph.D. in Physical Oceanography. Prior to joining Sea-Bird she was a research scientist at NOAA PMEL in Seattle, studying biophysical interactions, sea ice deformation, and internal waves. While there, she focused on developing novel techniques to study ocean processes using a variety of sampling platforms, including moorings, satellite tracked drifters, towed vehicles, and even land-based HF radars.

Kim's primary duties at Sea-Bird are the characterization and optimization of instruments, Navis customer support, and customer training. Her prior experience with all aspects of instrument deployment, from choosing instrumentation to recovery and data processing, will enable her to help Sea-Bird customers collect the best data possible.

Outside of work, Kim likes to bike, spend time outdoors, cook, tinker, and do outreach via social media. She can be found tweeting about marine science, data, and instrumentation @rejectedbanana.
