Pursuing Coordinated Coastal Planning and Broad Scale Implementation of Solutions in the Northern Gulf of Mexico
Natural and made-made disasters, coupled with a changing climate and significant increase in infrastructure development, have resulted in the loss and degradation of natural habitats, including wetlands, seagrasses, beach and dune habitats, and maritime forest. To address these acute and chronic issues, numerous large-scale projects have been initiated in some of the most vulnerable areas of the coast including urban, natural areas, and private and public lands.
Increasingly scientists are in a position to offer high-resolution predictions using advanced models and datasets to inform project development. This ability complements current levels of restoration and adaptation funding, growing public awareness of coastal resilience, and expanding forums to engage stakeholders. However, coordination is still needed across these interlocking activities, and across a range of spatial scales.
This session will focus on the efforts of multiple municipalities and agencies in the Gulf of Mexico, with specific emphasis on the Alabama and Mississippi coast. We will bring together partners across the predictive modeling, planning, implementation, and engagement landscape to discuss existing case studies and lessons learned for advancing effective coordination and moving towards actions and solutions.
Case studies will cover a broad range of topics including climate vulnerability, coastal resilience, adaptation planning, watershed management planning, habitat conservation and land acquisition, bird conservation, beach nourishment, shoreline stabilization, marsh restoration, and parks improvement and public access.
This session format will be a combination of individual speaker presentations, followed by a panel discussion to share challenges, experiences, and best practices associated with planning, design, construction, and public outreach of these broad-scale coastal projects. The end result will be increased awareness of opportunities for more coordinated, gulf-wide planning.
The Pelagic Gulf of Mexico: its Biodiversity, Ecology, Drivers, and Management
The Gulf of Mexico is the world’s 9th largest water body, with the majority (>90%) of its volume comprising the pelagic (open-ocean water column) domain. Extending from the outer continental shelf to abyssal depths, the pelagic Gulf is extraordinarily biodiverse in a global context. Research since DWH presents a picture of an extremely interconnected system, with the surface fauna feeding deep, the deep fauna feeding shallow, and both oceanic and coastal faunas using the open ocean as early life stage habitat. The pelagic Gulf is also a system subjected to severe chronic and acute human stressors in the form of resource extraction, pollution, biogeochemical alteration, and traffic (commercial, recreational, and military). These stressors occur against a backdrop of natural variability that is poorly understood. In this session we invite papers summarizing what we know and still need to learn about the Gulf’s largest ecosystem in order to facilitate management and mitigate further deterioration. Topics of particular interest include, but are not limited to, assessments of population levels, biophysical coupling, ecological connectivity, emerging threats, and management perspectives of commercial and protected species.
Practical Implementation of Regional Sediment Management and Methodologies to Reevaluate Coastal Sediment Sources
Coastal areas facing erosion exacerbated by storms and sea level rise need increasingly greater quantities of sediment for beach, dune, and marsh creation. Information on available material to support these projects is often limited because borrow area identification is typically confined to specific, relatively small areas, and data that do exist can be difficult to find or access due to being housed across databases within multiple agencies. New geological and geophysical data collection to support characterization of offshore sources, on the other hand, requires significant funds, dedicated planning, and complex interagency coordination. At the same time, new and expensive disposal alternatives are sought to replace rapidly filling disposal areas for sediment dredged from navigable waterways, material that may be appropriate for beneficial use. A solution to these interconnected challenges is Regional Sediment Management (RSM), a holistic, systems-based approach for stewardship of sediment resources to provide broad benefit.
This session is focused on issues related to practical implementation of RSM, from programmatic planning of sediment use to interagency leveraging of available data on sediment sources to beneficial use. Topics can range from sediment source to sink, including identification and quantification of sediment resources; strategies for resolving conflicting uses of borrow areas; evaluation and valuation of beneficial use opportunities; management of dredged sediment and sediment placement areas; and equitable and just management of sediment resources and the environment. Also of interest is repurposing of existing geological, geotechnical, and geophysical data to identify sediment sources through desktop analysis or application of new technologies (e.g., 3D analysis, artificial intelligence, and application of new geological or sedimentary models). Presentations may encompass applied research, case studies, and implementation strategies, with an emphasis on efforts where decision-makers, stakeholders, scientists, and/or engineers have worked collaboratively to develop and apply innovative approaches. The session will also include time for participants and attendees to discuss RSM challenges and opportunities as part of advancing innovation and regional collaboration on this topic.
Status of Corals in the Gulf and Caribbean Region
This session will bring together marine resource managers, researchers, aquarists, and NGO partners to discuss the current status of corals and threats, including bleaching, disease, and restoration challenges in the face of a changing climate.
Understanding Community Assemblages in Tidal Flats within the Gulf of Mexico
Tidal flats are critically important wetlands for primary production and habitat for a variety of fish and wildlife. In the Gulf of Mexico, tidal flat inundation and exposure are driven more by responses to wind than lunar tides and are therefore often termed “wind-driven tidal flats.” Tidal flats are often the primary wetland type on the bay sides of islands as well as along bay margins, river deltas and mouths of tidal creeks. Many wetland habitats across the Gulf of Mexico are receiving the necessary attention and resources for management and restoration. Tidal flats, however, have often been ignored due in part to less recognition of their importance and public perceptions of tidal flats as wastelands, devoid of emergent vegetation. A part of promoting the importance of tidal flats begins with an increased understanding of the community assemblages associated with tidal flats and the role tidal flats play in productivity of our bays and estuaries. Tidal flats provide important habitat for variety of vertebrate and invertebrate nekton, fish species especially juveniles, shrimp and crab species and a host of waterbird species including shorebirds and wading birds. This session will focus on species to community level studies of fish and wildlife that use tidal flat habitats for all or portion of their annual life cycle as well as studies related to the tidal flat primary producers (e.g. cyanobacteria) and the biotic and abiotic processes that influence formation and maintenance of these important wetland habitat. Additionally, tidal flats face threats associated with anthropogenic alterations to natural processes including rapidly changing sea levels, increasing storm frequency and intensity, and warming of surface and sea-surface temperatures. This session will also include studies that examine the dynamic processes of tidal flats and future net effect of these habitats in response to climate change.
