Integrated Ecosystem Assessment Stories
Over the past 10 years, scientists from all over the world and in the United States have achieved incremental successes in using the Integrated Ecosystem Assessment approach. This approach allows them to build relationships with scientists, stakeholders, and managers and balance the needs of nature and society for current and future generations.
Scientists are heading to sea on the R/V Walton Smith to sample areas where red tide blooms are commonly present off the west Florida coast. Karenia brevis, the organism that causes red tide, forms blooms when elevated concentrations (>100,000 cells per liter) are present in the water. K. brevis produces toxins called brevetoxins that can cause massive fish kills, weaken or kill marine mammals, and (if the toxin becomes aerosolized and inhaled) cause respiratory distress in humans and marine mammals. The team of scientists will be comprehensively sampling a series of transects along the West Florida Shelf.
The Florida Keys Integrated Assessment (IEA) team, led by AOML in partnership with managers and scientists from the Office of National Marine Sanctuaries, launched a new Ecosystem Status Report web tool on May 13th. The IEA approach aims to balance the needs of nature and society through Ecosystem-Based Management. It provides scientific knowledge of the Florida Keys National Marine Sanctuary ecosystem to scientists, policy makers and resource managers.
An analysis of 20 years of water quality data shows that Biscayne Bay, a NOAA Habitat Focus Area off southeast Florida, is degrading, as scientists have identified early warning signs that could help inform managers to prevent a regime shift of the bay’s ecosystem.In a recent study published in Estuaries and Coasts, scientists from NOAA and partner organizations detected an increasing trend in chlorophyll and nutrient levels from 48 monitoring stations throughout Biscayne Bay.
AOML recently led a multi-agency (NOAA/AOML, NOAA/SEFSC, State of Florida Fish and Wildlife Research Institute, Florida Fish and Wildlife Commission, NOAA/NESDIS, University of South Florida, MOTE Marine Laboratory and Aquarium, and University of Miami) research cruise to study the effects of Southwest Florida’s ongoing red tide. To address such a complex problem as red tide, the cruise brought together a diverse team of experts consisting of commercial fishermen, oceanographers, systems ecologist, phytoplankton ecologist, and fish population biologist. This cruise allowed researchers to take a holistic approach to characterize the extent of the red tide and its impacts. The goal of the cruise was to understand why these blooms happen to better inform effective future response measures and hopefully improve Florida’s resilience to these coastal events.
In August 2018, a team of biological oceanographers and ecologists set sail on the R/V Walton Smith to sample the waters of Biscayne Bay & Florida Bay. AOML has conducted regular interdisciplinary observations of south Florida coastal waters since the early 1990’s. We spoke with Chris Keble, the lead scientist for AOML’s South Florida Ecosystem Restoration Research project, to learn more.
AOML scientists recently returned from the first cruise of 2018. As part of the South Florida Project, regional surveys over the southwest Florida shelf and the Florida Keys reef tract are routinely performed aboard the R/V F.G. Walton Smith on a bimonthly basis, to keep a watchful eye over sensitive marine habitats found in the region. Sampling methodologies include discrete sampling and flow through measurements of water quality and chemistry, and biological oceanographic parameters.
Photo Essay Adjacent to Everglades National Park, Florida Bay encompasses the shallow waters, mangrove islands, and grassy banks between mainland Florida and the Keys; an area about 1,000 square miles in size. With an average depth of only 3 feet, the bay is home to a number of marine populations as well as a […]
With an average depth of only 3 feet, the Florida Bay is home to a number of marine populations, as well as a vital nursery ground for commercial and recreational reef fish species. The Florida Bay also plays host to a group of NOAA researchers who are investigating how habitat changes in Florida Bay are impacting juvenile sportfish populations, with a focus on the spotted seatrout.
AOML scientists aboard the R/V F.G. Walton Smith conducted the bimonthly water quality research cruise in support of the South Florida Project during the week of September 21st. The AOML South Florida Project (SFP), and its associated field operations, have enabled scientists and resource managers to keep a watchful eye on the sensitive marine habitats found in the region and have served as a sentinel during periods when the ecosystem has been subjected to extreme events such as hurricanes, harmful algal blooms (HAB), and more recently, potential oil spill contaminants. Additionally, the AOML SFP has produced a comprehensive, long-term baseline regarding regional circulation, salinity, water quality, and biology for the ecosystem.
