Determining the extent of saltwater influence on groundwater in Dr. Von D. Mizell Eula Johnson State Park.
Title
Determining the extent of saltwater influence on groundwater in Dr. Von D. Mizell Eula Johnson State Park.
Name/Creator
Deitsch, Adam Michael
Abstract/Description
Dr. Von D. Mizell-Eula Johnson State Park is a barrier island off the coast of Dania Beach, Florida. Situated between the Atlantic Ocean and the Intracoastal Waterway, with the brackish Whiskey Creek transecting the park from north to south, the park is home to several coastal ecosystems and poses an unique opportunity to collect valuable data to assess the impact of sea-level rise on the distinct ecological communities within. The park is managed by the Florida Department of Environmental...
Show moreDr. Von D. Mizell-Eula Johnson State Park is a barrier island off the coast of Dania Beach, Florida. Situated between the Atlantic Ocean and the Intracoastal Waterway, with the brackish Whiskey Creek transecting the park from north to south, the park is home to several coastal ecosystems and poses an unique opportunity to collect valuable data to assess the impact of sea-level rise on the distinct ecological communities within. The park is managed by the Florida Department of Environmental Protection Division of Recreation and Parks. Goals for the park management and protection include protecting the water quality and quantity in the park (including restoring hydrology to a feasible level), as well as restoring and maintaining the natural communities within the park. As studies have shown, changes of the salinity in the groundwater and surrounding soils can affect the viability of coastal forest habitats and cause a shift in ecotones. To this date, there have been no detailed studies on the extent of the groundwater dynamics within the park. With three bodies of water with differing salinity surrounding the park, the geological design should create four independent zones of saline lensing around the freshwater lenses within the two segments of the island. Installation of piezometers in east-west transects at regular increments from the north to the south could allow for the mapping of the transition from saline to freshwater within the park. Subsequent sampling and testing of temperature, salinity, and water depth, as well as other ambient factors, over a complete lunar cycle, would provide critical data in determining the extent of the tides and sea-level rise on park’s freshwater-saltwater interface. Understanding this dynamic flux is vital in preservation and restoration management plans, especially involving protection and reestablishment of at-risk or endangered species. This research will provide insight into predictable changes in the park’s communities. This knowledge can be incorporated into established Florida Department of Environmental Protection management and monitoring plan. Establishing long-term groundwater monitoring protocols can influence future protection and restoration projects with ground truth data. If successful, this type of monitoring can be expanded to other state parks of similar coastal geomorphological features.

Establishing a Long term Monitoring Plan for Hallandale Beach, Florida Nearshore Coral Reef Habitats.

Establishing a Long term Monitoring Plan for Hallandale Beach, Florida Nearshore Coral Reef Habitats.

Pollard, Madison Jane
Abstract/Description
The city of Hallandale Beach, Florida adopted the “Our Local Coral Reef Protection Ordinance” in June of 2019, with plans to restore their coastline and protect the community from future storm surges. Ordinance No. 2019 1- 011 added sections 5 to 8 in Chapter 13 "Health and Sanitation" of the city of Hallandale Beach code of ordinances, which outline strategies to protect and restore the resilience of the nearshore coral reef.

Show moreThe city of Hallandale Beach, Florida adopted the “Our Local Coral Reef Protection Ordinance” in June of 2019, with plans to restore their coastline and protect the community from future storm surges. Ordinance No. 2019 1- 011 added sections 5 to 8 in Chapter 13 "Health and Sanitation" of the city of Hallandale Beach code of ordinances, which outline strategies to protect and restore the resilience of the nearshore coral reef. Complex coral reef systems bring higher biodiversity and will raise the economic value of the reef to tourism. The length of Hallandale Beach shoreline is approximately 0.80mi (4200ft). Acropora cervicornis (Staghorn coral), a critically endanger species, is said to be found ½ mile off the coast of Hallandale Beach and is an important reef-building species to be monitored. This proposal will establish a long-term monitoring plan and baseline for the nearshore coral reef based on the Atlantic and Gulf Rapid Reef Assessment (AGRRA) protocols. It will briefly outline procedures needed to accomplish the three different monitoring surveys and important indicators each SCUBA diver will be required to record. Corals are the primary builders of reef habitats and they benefit from the presence of reef fish and benthic organisms. Reef fish have different eating habits that promote positive structure changes such as, keeping turf algae in check clearing room for recruitment of polyps. Benthic promotors such as, crustose coralline algae and minimal turf algae encourage a healthy reef habitat. According to a map of Broward County, Florida reef structure created by Brain Walker, the linear reef inner begins about 0.80 mi (4200ft) and the liner reef middle ends at about 1.75mi (9240ft) from the shore. There appears to be no linear outer reef off the coast of Hallandale Beach. There is no previous baseline to compare future surveyed data or confirm presence and density of diver sighted Acropora cervicornis. Baselines are important historical data that enables the city to identify changes in the complexity of the reef structure and responses to climate change to make proactive decisions. An initial baseline of Hallandale’s reef will be made to be comparable with future monitoring data, as well as determine the effectiveness of the management plans in place. AGGRA protocols require a minimum of six divers and with the use of city vendors, equipment costs can be as low as 230 dollars. Without a coral reef, the city may face costly damages from natural disasters such as hurricanes. Coral Reefs provide protection against storm surges that without, coastal erosion would increase and leave the city without an offshore defense against high energy wave action. AGRRA protocols will be applied to create a basic level survey easily adaptable, this will provide community building and outreach opportunities through citizen science and volunteering.
