Florida Sea Grant
This year marks the 35th anniversary of the annual Cortez Commercial Fishing Festival. For one weekend in February, this tough and tiny village will open its doors to thousands of visitors to share the proud history and culture of one of Florida’s last true working waterfronts.
Settled by fishermen from North Carolina in the late 1800s, Cortez has never stopped fishing. Its people have withstood hurricanes, wars, recessions and storms of regulations. The village has had to adapt to shifting sands – but the perseverance and grit of the people have never wavered. Today it remains a true testament to the “real” Florida.
This region has supplied bountiful seafood to humans for thousands of years. Fishing here is good for a reason. Nestled among mangroves on Sarasota Bay, Cortez is positioned between two nationally accredited estuaries. Quick translation: the habitat here is pretty special. However, like so much of Florida, Cortez faces threats associated with an increasing human population and ever-encroaching development. But unlike so much of Florida, where similar places have simply been swallowed by the concrete, Cortez has been fighting back.
In April of 2010, a gas release on the Deepwater Horizon oil rig caused an explosion that caused devastation in the Gulf of Mexico. Approximately 210 million gallons of oil spilled into the Gulf of Mexico over the course of 87 days to make this oil spill the worst one in recent history. Because of this oil spill, the coastlines of states like Texas, Louisiana, and Florida have portions that were polluted by the oil spill in 2010, and there are still sightings of oil washing up on these state’s shores today. Nearly 8,000 marine animals, such as turtles and birds, were reportedly dead within six-months of the oil spill.
Even though the Deepwater Horizon oil spill occurred over six years ago, scientists and researchers are still discovering the oil spill’s effects on the Gulf of Mexico. Come join us and Dr. Monica Wilson as she discusses recent research findings and explores the Deepwater Horizon oil spill’s impacts on habitats, aquatic wildlife, and human health.
This past summer, Florida’s Lake Okeechobee and St. Lucie Estuary became sheathed in toxic algal blooms. Do you know why these toxic algal events occurred? This month’s Salty Topics speaker series welcomes you to learn about the context of these events in a discussion presented by Dr. Karl Havens.
During early summer 2016, a bloom of the toxin-producing blue-green alga Microcystis began for form on the surface of Lake Okeechobee. By July, it covered nearly 45% of the surface of the lake with a fluorescent green surface scum. The bloom was fueled by high levels of nutrients (nitrogen and phosphorus) in the lake water that come from agricultural runoff, and by warmer than average water temperature and good underwater light conditions that were favorable for rapid growth. At the same time that this bloom was happening in the lake, the US Army Corps of Engineers was releasing large quantities of water from the lake in order to lower water levels in preparation for hurricane season. They are required to do this by a federally-authorized ‘lake regulation schedule.’ The flood control releases carried nutrients and toxic algae downstream to the St. Lucie Estuary, where massive blooms also developed and included another toxic species called Anabaena. As of late August, the blooms persisted and the ecological, human health and economic impacts have yet to be determined. A perfect storm created this event, and to fully understand it one must have some context about the regional flood control system and about sources of nutrients – topics to be discussed as part of this talk.
Karl Havens is a Professor at the University of Florida and Director of Florida Sea Grant, which is a NOAA-funded program that is a partnership between the Department of Congress, the State University System of Florida and Florida coastal communities. The mission of the program is to support research, education and outreach to preserve coastal resources and economies. Dr. Havens has been studying lakes for over 30 years and has published over 160 journal articles, three books and numerous book chapters dealing with harmful algae and other topics related to human impacts on lake ecosystems.
Do you know that Tampa Bay’s coastal ecosystems soak up and store carbon in a process called Coastal Blue Carbon? If not, come join us and Dr. David Tomasko for our Salty Topics speaker series!
Coastal Blue Carbon is a new term for carbon captured by living coastal and marine organisms and stored in coastal ecosystems. Mangroves, sea grass beds and salt marshes take up atmospheric carbon and store it in their systems throughout their life cycle. Also, these plants trap fine muddy sediments in their roots structures building thousands of years. Tampa Bay is a unique ecosystem as it is one of the few places in the U.S. to have three critical coastal habitats – mangroves, salt marsh, and seagrasses. Dr. David Tomasko, Principal Associate ESA, will share the results of the Tampa Bay Blue Carbon Project that was jointly funded by the Tampa Bay Estuary Program and Restore America’s Estuaries.
The presentation will include:
• Carbon storage and sequestration rates for Tampa Bay habitats
• Impacts of land use change, including sea-level rise and management actions, on carbon in the estuary
• How blue carbon ecosystem services can inform management decisions and provide additional incentives to support conservation and restoration and adaptive management
Duh-dum, duh-dum, duh-dum, …Shark Week! Well friends, it is that time of year again. Sharks take center stage this week on cable television. With all the hype, it can be hard to separate the fact from the fiction. Are sharks friends or foe? Perhaps they are not either. Perhaps we should look at them as oft-misunderstood, ecologically-important predatory ocean fish. So what are sharks?
Sharks ARE ancient. Sharks are sometimes referred to as “living fossils”. Ancient sharks lived in the oceans long before animals colonized the land. Sharks have lived on earth for at least 400 million years! Most fossil evidence of early sharks exists as fossil teeth along with a few skin impressions. Ancestry of sharks dates back before the earliest known dinosaur. Although the dinosaurs are long gone, sharks still live on.
All of us with the southwest Florida Sea Grant Extension Program wish all of you a great holiday season. It is truly an honor and privilege to work with so many dedicated citizens and scientists along the coast. As the years pass, change occurs. However, one thing that doesn’t change is the great nature of the folks we work with. We hope 2013 is good to all of us.
