Sea-Bird Scientific LOBOs Monitor Hurricane Irma's Wrath
Above: Salinity (top) and turbidity (bottom) data captured leading up to, and during Hurricane Irma.
The center of Hurricane Irma may have missed Florida’s eastern shore, but its effects did not. Florida Atlantic University’s Harbor Branch operates a network of Sea-Bird Scientific Land/Ocean Biogeochemical Observatories (LOBOs) in the Indian River Lagoon that captured the edge of Irma’s wrath in real time. The peak of the storm occurred just before midnight on September 10th as the air pressure dropped to 990 mbar and wind speeds topped out over 45 mph.
In the Indian River Lagoon, Sea-Bird Water Quality Monitors (WQM) measured the increase in water level due to storm surge and increased turbidity due to winds stirring sand and sediment up from the lagoon bed. Further inland in the estuary, salinity values dropped as fresh rainwater gushed from the St. Lucie River. Interact with this data and view more of the effects of Hurricane’s on eastern Florida at the LOBOviz website.
Sanibel Captiva Conservation Foundation's custom data chart can sort and display LOBO data on the southwest coast. Plotting yearly rain (cumulative) with turbidity and salinity for the Fort Myers location in September reflects the large rain event, resulting in high turbidity and a subsequent drop in salinity due to Irma passing through.

Our thoughts are with all Floridians and our affected customers, with whom we have continued close relationships that reach back over many years. We hope they and their families are safe.
Irma Creates High Turbidity Along The Keys
NOAA released before and after images of sand along the south coast of Florida to showcase the impact of Irma on sand distribution. According to the Florida Keys National Marine Sanctuary, "the continental United States’ only barrier reef provides a buffer for the Florida Keys during storms, decreasing impact on lives and property. Minor hurricanes may clear the reef of dead organisms and even enhance biodiversity, however strong hurricanes often result in significant damage, depleting the natural barrier and important marine life habitat."
The image, showing Florida's southern tip, the Florida Keys, and the Bahamas clearly shows vast disturbance of the sand being suspended in the water, causing a large increase in turbidity, and changing the ecosystem.
Irma's strongest wind gusts were on the north side of the storm, or the west coast of Florida and the Keys. NOAA's National Hurricane Center logged Irma's maximum sustained winds ranging from 110 (on 9/10) to near 180 (on 9/7) miles per hour during this period.
Argo Profiling Float and Sensor Workshop
The University of Washington (UW) hosted a workshop for users of Argo floats and sensors last week in Seattle, Washington. Roughly 50 members of the global community attended the meeting, which was held to provide a forum for establishment of best practices and improved performance across the fleet of profiling floats.
Our invlovement was two-fold: we provided presentations on the present and future states of the Sea-Bird 41CP CTD and Navis Profiling Floats and our Bellevue site hosted a tour of our facilities for all the attendees, with much interest by all those who made the tour.
Sea-Bird at Oceans'17 MTS/IEEE in Anchorage this Week
Sea-Bird Scientific is exhibiting this week (September 18 - 21, 2017) at Oceans'17. in Anchorage, Alaska The focus of the event this year is "Our Harsh and Fragile Ocean". If you are attending, plan to drop by our booth (# 709) to meet with us and discuss your programs, applications, and plans. Members of our Science and Sales team will be there to answer your questions.
Dave Murphy, Director of Science (pictured above) hosted a workshop on SUNA Nutrient Sensor Measurements, Calibration and Application on Monday, September 18th and a seminar entitled Oceanographic Instrumentation and Sensors, the following afternoon (Tuesday).
UCI 1.2.3 Release
UCI 1.2.3 for Windows and MacOS has been released. We recommend that all customers using SUNA, Deep SUNA, HydroCAT, or HydroCAT-EP should upgrade to UCI 1.2.3.
Please refer to the release notes for the list of fixes and improvements.
Note that the original release of this newsletter had 1.2.2 as the release. UCI 1.2.3 was released a few days later. The link below will always send you to the latest version.
Tech-Tip: Monitoring Run-off During Storm Events
We need not be reminded that hurricane season is not yet over and there are many storms ahead that require monitoring. Regardless of the strength of storms, monitoring runoff during storm events is a key part of any continuous monitoring program. Water quality conditions can change quickly, and spot sampling while the event is occurring is not always possible. Data collection during these events is needed to assess the effectiveness of stormwater management best practices. For that reason, we recommend that you take a look at a number of Sea-Bird sensors
that are suitable for such a situation, allowing for assessment of water quality issues during storm events.
Meet Our People: Adam C. Dutton, Technical Support Manager
Adam has been with Sea-Bird Scientific for over 7 years. Prior to joining Sea-Bird, Adam worked with an NGO named International SeaKeeper Society as a calibration technician, installing autonomous atmospheric and oceanographic systems on cruise ships, ferries, private yachts, buoys, and research vessels.
Adam joined Sea-Bird as a Service Technician in 2009 and moved on to work as a Field Deployment Specialist, helping customers with their deployments, product demonstration and training. Adam has been in his current role as Support Manager for 2 years now and is responsible for managing and mentoring a team of Technical Support Specialists from all three sites (Bellevue, Philomath and Halifax). Adam is also responsible for providing technical support on escalated issues and supporting his team on an ongoing basis.
In his personal time, Adam enjoys reading novels, and about history and political economics. He also enjoys live music and performance art from symphony and ballet to small time folk artists and large venue rock concerts, which made him travel to Taipei in 2016 to see Sigur Rós (rock band)! Adam also enjoys travel of all kinds and has logged a lot of miles in the air for both work and pleasure. His goal is to fill up all the pages in his passport before it expires!
