An investigation of mechanisms that drive compounding connections between tropical cyclones and marine heatwaves in the coastal ocean

Project Leader:Dr. Brian Dzwonkowski Project Details Primary Research Areas: The proposed project will investigate interactions between marine heatwaves, tropical cyclones, and climate modes, which addresses fundamental questions related to air-sea interaction and is directly related to a primary scientific goal of the NASA physical oceanography program by improving the ‘understanding of the ocean’s role in climate variability and its prediction’. Broadening the understanding of the role of the coastal ocean and its associated air-sea couplings in generating extreme events (i.

Center for Environmental Resiliency

Project Leader:Dr. Brian Dzwonkowski Project Details The project addresses overreaching research questions related to how and why hypoxic conditions change in response to both natural conditions and increased anthropogenic pressures present in the Alabama coastal waters. The study is identifying and improving the understanding of the structure, variability, and impacts of dissolved oxygen patterns in estuarine systems of Alabama.

DISL Coastal Ocean Observation systems

Project Leader:Dr. Brian Dzwonkowski Project Details Lead investigator involved in maintaining site CP, a long-term mooring site collect water column velocity and hydrographic data. This is one of the longest running high frequency hydrographic times series in coastal water of the Gulf of Mexico and has a tremendous potential for being a sentinel site for address anthropogenic impacts in the coastal zone (e.g., watershed urbanization, climate change issues). Interdisciplinary data from this have been used in a range of ways by numerous scientists.

Expansion of

Project Leader: Renee Collini, co-leader Dr. Brian Dzwonkowski Project Details NOAA RESTORE ACT Science Program - Expansion of for coastal Alabama resource management Project Effective management of coastal estuaries requires real-time and historical knowledge of water quality such as salinity, temperature, dissolved oxygen, and turbidity. Unfortunately, many Gulf of Mexico coastal regions lack web-based tools that effectively integrate available water quality data so that resource managers and stakeholders can efficiently use incoming data to make information decision related to the marine environment (for example, closure of oyster harvesting areas).

GoMRI Consortium for oil spill exposure pathways in Coastal River-Dominated Ecosystems (CONCORDE)

Project Leader:JProject Leader: Monty Graham (University of Southern Mississippi) Project Details This project addresses how complex fine-scale structure and processes in coastal waters dominated by pulsed-river plumes control the exposure, impacts and ecosystem recovery from offshore oil spills. CONCORDE has been focused on understanding sub-surface modes of Oil Derived Substance transport and chemical change as it relates to organism exposure in coastal waters dominated by pulsed-river plumes. A central component of this program is seasonal transects across the Mississippi Bight shelf with coupled biophysical measurements.

MBNEP Fowl River Marsh Study

Project Leader:Dr. Just Cebrian Project Details The success of estuarine restoration efforts often depends on a range of interdisciplinary marine and fluvial process that interact in complex ways. Physical forcing is a critical factor in controlling the environmental conditions that biogeochemical and ecosystem processes must operate. Thus, a major consideration in estuarine restoration is the physical conditions at site locations due to their importance in determining whether biological organisms can survive and flourish.

Mississippi Water Resources Research Institute

Project Leader:National Estuarine Research Reserve System (NERRS), Grand Bay Project Details The project focuses on improving the understanding of water quality in Bangs Lake, a region effected by recurrent phosphate spills from an adjacent chemical plant. Dr. Dzwonkowski’s component of the project focuses on accurately describing circulation and dispersion processes in a shallow salt marsh system. This experiment involved tracking of a dye release, deployment of a short-term moorings (ADCP, CTDs, and ADVs), and the release of surface drifters.

NASA SUSMAP: SMAP observations to trace the lifecycle of hydrologic extreme events

Project Leader:John Reager (NASA JPL) Project Details SMAP is a remote sensing observatory that carries two instruments that will map soil moisture and determine the freeze or thaw state of the same area being mapped. This project is a collaboration with scientists from the Jet Propulsion Laboratory (JPL) to explore the temporal and spatial domain of flood events and their impacts, encompassing both terrestrial and oceanic regions. The primary objective of the work will be to understand the mechanisms of flood generation and progression, and to characterize the contributors to land and ocean event severity.

Using shelf monitoring to assess multi-stressor impacts on dissolved oxygen dynamics and hypoxia in a changing coastal climate

Project Leader: B. Dzwonkowski (PI), J. Lehrter, and D. Tian Project Details Shelf hypoxia is a well-recognized management issue for a growing number of coastal regions (Diaz and Rosenberg 2008) that can alter food web dynamics and biogeochemical cycling, resulting in threats to fisheries, coastal economies, and ecosystem health (Breitburg et al. 2009; Diaz and Rosenberg 2011). While hypoxia is often associated with excess nutrients delivered by freshwater inputs, a number of recent studies have indicated the interannual variability in physical forcing functions are as important (in some cases more important) than nutrient loading.
