- Addressing Marine Megafauna Bycatch
Lead: Jeremy Kiszka
Project Title: Addressing and mitigating marine megafauna bycatch
Bycatch, or the incidental capture of marine mammals, seabirds, sea turtles and elasmobranchs is the most significant threat to these species at the global level. The magnitude of bycatch is overlooked in many regions around the world, particularly in developing countries, and actions to mitigate bycatch are still rare in most fisheries.
Working with our partners (including WWF Pakistan, Newcastle University, International Whaling Commission, US Marine Mammal Commission and Oceans Initiative), we investigate the magnitude of the incidental capture of marine megafauna and how to mitigate bycatch, primarily in small-scale fisheries. We also study how some industrial fisheries overlap and affect some endangered species, particularly cetaceans. We work regionally (East Africa, Arabian Sea) and globally to quantify and mitigate marine megafauna bycatch across multiple fisheries.

- Small-Scale Fisheries Management
Project Title: Small Scale Fisheries Research Projects
Overfishing has been recognized as one of the biggest environmental and socioeconomic problems facing marine ecosystems since it reduces biodiversity and alters ecosystem functioning. Fishing is often size-selective causing catches to be concentrated on large-bodied species including elasmobranchs (sharks and rays). Although research efforts have mostly focused on the effect of industrial fisheries on elasmobranchs, small-scale fisheries account for more than 95% of fishers in the world. Given their wide occurrence and the large number of people dependent on fishing, small-scale fisheries are an important economic sector and their impact on vulnerable elasmobranchs may be significant. However, in these types of fisheries, detailed information on catch composition is limited due to a lack of monitoring and reporting. In addition, the flexible and informal nature of most artisanal fisheries (e.g. broad range of targeted species, diversity of gear used) makes them difficult to study, in terms of catch statistics of targeted species and bycatch.
Thanks to the support of Save Our Seas and collaborators like Pontificia Universidad Javeriana de la Compañía de Jesús, Parque Nacional Natural Corales de Islas del Rosario y San Bernardo, ReGuaR, Kap Natirel, and the Environmental Research Institute of Charlotteville, Tobago, Ph.D. student Camila Caceres is sampling artisanal fishers to learn more about the elasmobranch and human communities that survive along Caribbean coastlines.
- Fisheries Management Strategy Evaluation
Lead: Yuying Zhang
Project Title: A decision-support tool for evaluating the impacts of short- and long-term management decisions on the Gulf of Mexico red snapper resource
Management strategy evaluation uses simulation methods to quantify the risk associated with a suite of potential fisheries management actions. Management of the Gulf of Mexico (GoM) red snapper resource over the last three decades has been controversial and contentious. The need to develop a management strategy evaluation tool that can test the robustness of long-term management strategies and short-term regulations has been indicated in the recent stock assessment reports. For complex fisheries like GoM red snapper, a customized decision-support tool is needed, based on a broader MSE framework that allows for a more holistic evaluation of alternative management strategies. This project is funded by NOAA Restore Act Program. You can test our newly developed web-based GoM red snapper MSE decision-support tool here: http://gomredsnappermsetool.fiu.edu/.

- Climate Resilient Urban Nexus CHoices (CRUNCH)
Lead: Thomas Spiegelhalter
Project Title: Miami Climate Resilient Urban Nexus CHoices (CRUNCH)
CRUNCH is a three-year project that explores the food, water, energy nexus. It is running from 2018 - 2021 and will build an Integrated Decision Support System, which is an assessment tool for cities.
The City of Miami Beach is one of the most climate vulnerable cities on planet Earth. In the coming decades the city will have to face the challenges of sea-level rise combined with yearly threats of hurricanes, king tides, and tropical rain downpours that can dump as much as five inches of water on the city in one afternoon.
Each semester the Miami CRUNCH research team will publish a volume of work based on design scenarios that have been developed with graduate students at the Urban Living Lab in Miami Beach. The team aims to publish book volumes focusing on different ways to respond to climate impacts through sustainable architecture. In their first volume, the team looks at designing building structures that can act as hybrids sitting in, out, or under the water with the ability to be self-sustaining.

- Direct-ageing Technique for Gulf and South Atlantic Spiny Lobster
Lead: Mark Butler
Project Title: Development of a direct-ageing technique for Gulf and South Atlantic Spiny Lobster for age-based stock assessment
No fishery is more iconic or valuable to Florida and the Caribbean than that for the Caribbean Spiny Lobster, Panulirus argus. Yet, proper management of lobsters has been hampered by our inability to directly determine their age. Standard techniques for fishery stock assessment are largely age-based but unlike in fishes and mollusks, whose age can be determined from growth bands deposited in calcified structures, determining age in crustaceans has proved elusive.
We are testing in P. argus the efficacy of a new method proposed for aging crustaceans that uses growth bands in the gastric mill ossiciles (part of the lobster stomach) to accurately ascertain lobster age. Laboratory studies of lobster growth along with collections of lobsters from fisheries in the Florida Keys, Dry Tortugas, and various Caribbean locations will allow us to construct size-at-age models useful for fishery management in each area.
This project is funded by the NOAA Marine Fisheries Initiative.

- Effects of Projected Sea-Level Rise on the Everglades
Project Title: Effects of Projected Sea-Level Rise on Everglades Coastal Ecosystems
This study identifies potential mechanisms for how salinity and saltwater inundation contribute to peat loss in freshwater and brackish wetlands, which can be used to inform Everglades and South Florida water management decision and more broadly inform ecosystem management of coastal landscapes worldwide. The outcome of the study will have immediate application to water and environmental management needs, and has been designed with end-users (e.g., SFWMD) to ensure that information will be readily accessible to water managers and decision makers. This project will continue to increase our understanding of the net effect of increased salinity and inundation specifically examining the effects of chronic and acute saltwater intrusion events on Everglades coastal peat communities.
- Florida Building Commission Project
Lead: Jayantha Obeysekera
Project Title: Potential Implications of Sea-Level Rise and Changing Rainfall for Communities in Florida using Miami-Dade County as a Case Study
The overall effort to assess flood risk may be accomplished by comparing existing flood elevations with new elevations based on updated rainfall data and sea-level rise projections. For the contract, SLSC evaluated groundwater level due to sea-level rise and changes in extreme rainfall in Miami-Dade County and potential implications for the current Florida Building Code.
- Land Subsidence and Coastal Flooding in South Florida
Lead: Shimon Wdowinski
Project Title: Land subsidence contribution to coastal flooding hazard in southeast Florida
Over the past decade, several coastal communities in southeast Florida have experienced a significant increase in flooding frequency, which has caused disturbance to property, commerce, and overall quality of life. The increased flooding reflects the contribution of global, regional, and local processes that affect elevation difference between coastal communities and rising sea level.
In a recent project, funded by the state of Florida, we monitor coastal subsidence in southeast Florida using GPS and spaceborne radar observations, in order to evaluate the contribution of local subsidence to the increased coastal flooding hazard.
As part of the project, we constructed a network of four continuously operating GPS (cGPS) stations that monitor land subsidence with accuracies of millimeters per years (Figure 1). Each station is equipped with precise GPS antenna, a monument holding the antenna, solar panels, and cellular communication, and an explanation plaque (Figure2). The spaceborne radar observations enable the detection of building movements over wide areas, also with accuracy of millimeters per year.

- Mercury Cycling at the Arctic Ocean Air-Sea Interface
Lead: David Kadko
Project Title: Constraining the role of chemical transformations on the cycling of mercury at the Arctic Ocean air-sea interface
This project will provide new understanding about mercury exchange between the air and sea surface in the Arctic, in conjunction with studies of the forms of mercury in seawater. Results will help predict how increasing ice melt and warming waters will affect mercury levels in polar regions. The investigators will use a novel approach of comparing the dynamics of radon, an unreactive gas, and mercury, which is reactive in all its forms, to understand the importance of chemical and biological reactions influencing mercury levels in seawater. Results will be useful for the international Minamata Convention and resource managers concerned with mercury bioaccumulation in humans and wildlife.
The goal of this collaboration is to better understand mercury cycling in the Arctic, and any dependencies that would give insight into how cycling may change in the future.

- Novel Mariculture of the Caribbean King Crab
Project Title: Novel Mariculture of the Caribbean King Crab for Market and Coral Reef Restoration
We are investigating the potential for the semi-wild mariculture of the Caribbean King Crab for use in coral reef restoration and, perhaps for the commercial seafood market, through the unique use of underutilized, land-locked saltwater quarries in south Florida where the crab already occurs or can be introduced. Our approach is based on first investigating the environmental conditions in salt-water quarries throughout the Florida Keys to assess their suitability for mariculture, comparing crab population dynamics and productivity in quarries versus natural habitats, and assessing the genetic structure of crab populations in the wild and in land-locked quarries.
This research is funded through the NOAA-National Sea Grant “Exploring New Aquaculture Opportunities” Program.

- Protecting South Florida Archeological Sites with Integrated Ecosystem Restoration
Lead: Randall Parkinson
Project Title: Stabilize and Protect South Florida Archeological Sites with Integrated Ecosystem Restoration
Cultural resource sites are found throughout South Florida in a variety of environmental settings. These sites date to both colonial and pre-colonial times and are mostly found in close proximity to the coastline or are embedded in surrounding wetlands. As a consequence, these sites are vulnerable to the effects of accelerating sea level rise and anthropogenic climate change that will bring higher tides, more frequent strong hurricanes and increased erosion.
This five-year project was designed to quantify rates of shoreline change associated with contemporaneous wave and tide conditions at three high-priority sites located in Everglades National Park using high-resolution 3D scans and contemporaneous water level data collected during winter and summer conditions. Results will help inform resource managers on the level of future risk to these resources caused by climate change stressors.

Such efforts include, but are not limited to, the Florida Protection Level of Service (FPLOS) program, Water Supply Planning, and CERP Planning/Everglades Restoration. As a first step in this process, FIU organized a workshop on May 16, 2019 to be attended by a selected group of experts in the field and representatives of various agencies, governments, and private sector.
- Restoring Coral Reefs in the Florida Keys
Lead: Mark Butler
Project Title: Restoring coral reefs in the Florida Keys by stocking native herbivorous crabs and corals
Florida’s coral reefs have reached a threshold whereby their resilience has been compromised, species are endangered, and ecosystem function degraded. There is a human cost too. Coral reef-associated tourism and fishing generate about $8billion per year and support more than 70,000 jobs in the Florida Keys alone.
A big contributor to reef degradation has been the phase-shift from coral to macroalgae dominance that has diminished coral health and recruitment. We are testing a novel, two-pronged approach to coral reef restoration: (1) improve reef habitat for corals and other species by transplanting native, herbivorous crabs onto reefs to graze and reduce macroalgae, and (2) then increase coral density on reefs through coral transplantation, to help rebuild coral spawning biomass.
This project is funded by grants from the National Fish and Wildlife Foundation and the Florida State Wildlife Grants Program.

- Coastal Fish Ecology in the Everglades
Lead: Jennifer Rehage
Institute scientists are passionate about fish and fisheries and the issues that affect them, particularly water and climate issues and their interacting effects. We focus on understanding how water and water management decisions interact with climate patterns to affect fish and the quality of recreational fisheries. Ongoing research efforts aim to understand how fishes move through their seascapes, what drives these movement, how those movements fit into large-scale ecosystem processes and what are the consequences for socio-economically valuable recreational fisheries. Our research mainly takes places in the Everglades and coastal South Florida, and we focus on key recreational species such as: Tarpon, Snook, Bonefish, Florida Bass, Jack Crevalle, and Redfish.

- Epigenetics - NSF Understanding Rules of Life (URoL)
Project Title: Predicting phenotypic and eco-evolutionary consequences of environmental-energetic-epigenetic linkages
Living organisms may acclimate to environmental changes through epigenetic modifications to DNA, which alter the way genetic instructions are interpreted without altering the DNA code itself. While these modifications to organismal phenotype or function can be reversible, some of them may be inherited by offspring, potentially producing multiple, heritable outcomes from a single genome and affecting ecological and evolutionary outcomes. This project uses symbiotic, metabolically complex reef building corals as a model system to test the connections between physiological, epigenetic, and metabolic states, and predict how population and community dynamics are influenced by epigenetically-modulated phenotypes. This work will advance biological knowledge by delineating fundamental links (Rules of Life) between ubiquitous organismal energetic processes, epigenetics, and eco-evolutionary outcomes.
- Hurricane Effects on Spawning Aggregations of Goliath Grouper
Project Title: Storm and tropical cyclone effects on the spawning activity, larval dispersal, and ecosystem impacts of an endangered marine predator
Spawning aggregations, where large numbers of fish from across a broad area assemble to reproduce at a single site, are a critical component of the life-cycle of many fish species. Environmental conditions are critical for spawning success, including water temperatures and currents, and for that reason spawning behavior tends to be predictable in both time and space. Spawning activity is critical to population dynamics for many species, and missed spawning events can dramatically reduce annual recruitment and dispersal. While much work goes into identifying and protecting spawning sites, less is known about how disturbances, such as those caused by hurricane/storm events, may impact spawning aggregations.
Large-scale weather events lead to dramatic changes in surge, waves, and physical energy, along with potentially dramatic declines in salinity due to freshwater inputs, both of which are likely to change spawning behavior. These changes (e.g. delayed, ineffective, or missed spawning events) are likely to have significant negative effects on population dynamics. However, for a recovering species, altered dispersal patterns could also potentially benefit the population by delivering larvae to new, but historically occupied, locations. When spawning aggregations are for large predators (e.g. grouper), changes due to disturbances can also have trophic consequences on prey species.
This project will, for the first time, document the impacts of a major disturbance on a fish spawning aggregation. Such data are particularly critical given predictions of increased storm activity because of climate change.
- Marine Macroalgae Connections to the Environment and Other Organisms

- Saltwater Intrusion and the Everglades
ProjectTitle: Experimental Saltwater Intrusion Drives Rapid Soil Elevation and Carbon Loss in Freshwater and Brackish Everglades Marshes
A team of Institute researchers set out to determine if and how saltwater intrusion can cause coastal wetlands to sink. Their findings demonstrate local actions can play a large role in the resilience of ecosystems to climate change. Through effective ecosystem management, wetlands could play a key role in staving off sea level rise. Read this FIU News article to learn more about this project.
Additionally, our experts have also found that the Everglades is seeing increased threats from sea level rise, like peat collapse. Our researchers are investigating how to address this challenges in an effort to protect the Everglades and, thus, incorporate wetlands in addressing the effects brought on due to climate change.
- Scaling Up Sponge Community Restoration in South Florida
Lead: Mark Butler
Project Title: Scaling up Sponge Community Restoration in South Florida to Improve Nearshore Water and Habitat Quality
Declining water quality in south Florida is a real and frightening prospect for the health of this iconic ecosystem, as well as for the tourism- and fisheries-based economy of the region. For over a decade, our researchers have sought to understand the ecological structure and function of the region’s shallow, nearshore sponge-dominated hard-bottom communities that in some areas have been decimated by harmful algal blooms. Our current research focuses on better understanding the effects of sponge community assembly and diversity on ecosystem functions such as water column filtration, provisioning of nursery habitat, and contribution to underwater soundscapes along with the potential for improving coastal water quality through the large-scale restoration of sponge communities.
This research has been funded by the EPA South Florida Initiative, The Nature Conservancy-NOAA Community-Based Habitat Restoration Program, and the Florida Sea Grant.

- Epigenetics of Corals in Response to Hurricanes Irma and Maria
Lead: Jose Eirin-Lopez
Porject Title: Interaction between genotype and acquired environmental modifications during coral responses to hurricanes Irma and Maria in Puerto Rico
After the impact of two consecutive category 5 hurricanes in less than a month, Puerto Rico is (for a narrow window of time) the world's best natural laboratory to study the effects of extreme weather episodes on coral reefs and the mechanisms underlying coral acclimatory responses to global change. This project leverages this opportunity, and the research team's previous work in the area, to understand how coral existing genetic variation interacts with acquired environmental modifications (i.e., microbiome and epigenome) during intra- and trans-generational responses to extreme climatic events.
This work is undertaken by a multi-institutional team, providing much needed answers to questions concerning the mechanisms by which foundational species acclimatize to rapidly changing environmental conditions. By better understanding the mechanisms contributing to stress responses, the researchers hope to learn how long lived sessile organisms may adapt or acclimatize to a extreme events. Established resources at Florida International University, the University of Puerto Rico, and Pennsylvania State University recruit and engage graduate and undergraduate students from under-represented groups in science in the research. The research team works closely with Puerto Rican agencies and local resource managers to communicate management and conservation applications from the research.

- French Polynesia Reef Shark Research
Project Title: French Polynesia Reef Shark Research Projects
Do healthy reefs need sharks? In October 2013, our scientists launched a study of the reef sharks that inhabit the coastal waters of Mo’orea, an island in French Polynesia. Using animal borne (or shark cams) and stationary cameras, the goal of the study is to investigate the feeding and behavior of a variety of reef sharks, especially blacktip reef and sicklefin lemon sharks, and their importance to the health of the reefs. Because Mo’orea offers shark feeding as a tourist attraction at designated sites, one goal of this study is understand how feeding of sharks changes their behavior and their role in the ecosystem.
Our researchers are exploring how emerging video technologies may offer a solution by providing inexpensive and non-invasive ways to survey sharks in remote, data-poor regions.

- Investigating Marine Organisms with Underwater Acoustics Technology
Lead: Kevin Boswell
Our scientists explore the world of deep ocean life by using advanced underwater acoustics technology to monitor what happens under the sea. They investigate deep-pelagic communities on short-term (sub-generational) and long-term (evolutionary) timescales to appraise extant recovery and potential future recovery of these communities. They also study sound scattering layers (SSLs) used by euphausiids, crustaceans, siphonophores and myctophids, which are prey for larger predators, like marine mammals, allowing our experts to explore predator-prey interactions. Our experts also use autonomous survey vehicles to perform acoustic surveys in shallow coastal waters (e.g., estuarine systems), collecting high-resolution data of the substrate characteristics, bathymetry and the organisms distributed above the seabed.

- Ocean Life Public Seminar Series
The Ocean Life series brings renowned researchers and academics to the Keys to educate, entertain and inspire audiences of all ages. Hosted by our Center for Coastal Oceans Research and the Friends of the Key Largo Cultural Center, the series features interdisciplinary experts from FIU and the Keys.
- Sea Level Solutions Center Citizen Science
Seasonal King Tides (the highest of the high tides) have been causing flooding in our Miami community. SLSC, in collaboration with several partners, hosts yearly volunteer events to collect sea level rise data through flood reporting.
- Sea Level Solutions Interdisciplinary Research & Design Studio
Sea Level Solutions Interdisciplinary Research & Design Studio
This course provides an innovative and creative platform to work collaboratively across disciplines to design and produce sea level solutions that are at once functional and visionary in their approach, in addition to serving as a model for our region and beyond. Faculty from multiple FIU colleges are among instructors and will provide weekly lectures (open to the public), training and analytical tools.
The studio will pay particular attention to infrastructural solutions that are concurrently functional, aesthetic, and contextual in their design approach. Students will be expected to deliver projects that are formally resolved in macro and micro scales, and will conduct research and analysis, site investigation, mapping and interpretation of the existing context. They will carry out studies aimed at exposing important site qualities and relationships. Ideas will be discussed in the form of desk crits and formal reviews, with special emphasis on frequent, in-class pinups and interdisciplinary group work.

- Public Education and Outreach - Communicating Sea Level Rise
Project Title: Communicating Sea Level Solutions
Robert Gutsche, Susan Jacobson, Kate MacMillin and Juliet Pinto of FIU won Eyes on the Rise: Sea Level Rise South Florida in 2014-2015. Their project entitled “Sea Level Rise South Florida: How Are Waters Affecting You?” presented ways of communicating sea level solutions while building community awareness and inspiring action.
- Sea-Level Rise and Projected Impacts
Project Title: Predicting Urban Flooding
GIS Coordinator, Pete Harlem, mapped sea level rise in South Florida which predict urban flooding patterns. Ivan D. Haigh, Thomas Wahl, Eelco J. Rohling, Rene M. Price, Charitha B. Pattiarachi, Francisco M. Calafat and Snoke Dangendorf are creating timescales to detect a significant acceleration in sea level rise. Through their findings, they will know if sea level in 2100 will increase by 1.5-2m (by 2020) and 0.5-1 (by 2030).
- Sea-Level Rise, Peat Collapse and the Everglades
Project Title: Effects of sea-level rise and freshwater management on long-term water levels and water quality in the Florida Coastal Everglades
Scientists found that reduced freshwater delivery to the Everglades is increasing salinity in drinking water wells through their study analyzing data from 2003-2012. Researchers examined sea level rise and South Florida coastal forests and found new evidence of the collapse of peat soil. In their study, looking at 50 years of coastal vegetation change, scientists found that sawgrass marshes in Everglades National Park is at risk of peat collapse. Additionally, they discovered that mangroves are displacing sawgrass marsh at rates up to 10 km per 50 years. They have conducted experiments to determine the consequences of SLR to marshes.
- Sustainable Communities and Transportation Planning
Project Title: Designing a Resilient City
The project looks at the city, neighborhood and building scale. It won the Florida Foundation for Architecture Award as well as the Provost’s Award for Outstanding Creative Project and the A|A Miami Design Awards. The project was exhibited at the Coral Gables Museum in 2014, Miami Beach Urban Studios in 2013 and the Association of Climate Change Officers in 2013.

- Water Supply, Management and Infrastructure
Project Title: Measuring Impacts of Flood Mitigation on Water Quality
Measuring the impacts of flood mitigan on water quality has been one priority. There have been routine assessments of the effects of urban flooding on water quality in Marine Protected Areas. Henry Briceño of the School of Environment, Arts and Society examined the King Tide Day in 2014 at Miami Beach. The regulated total nutrients (TP, TN) and CHLa were within range, but dissolved nutrients, SRP and DIN were up to six times the historic averages concentration.
