Hillsboro/Deerfield Beach 2015 Beach Nourishment Biological Monitoring – 2016 to present

 Project includes monitoring of physical and biological characteristics to determine potential impacts following the 2015 truck-haul beach nourishment event

  • Monitoring includes:
  • Hardbottom Edge Mapping

 Map the most prominent sand-hardbottom interface or consolidated nearshore hardbottom edge  Comparison to previously mapped edge, helps to identify persistent hardbottom areas vs. ephemeral areas

  • Nearshore Monitoring Transects

 Sediment Depth Measurements  Sand-Hardbottom Intercept Measurements  Benthic Characterization: BEAMR

  • Comparison with data collected from past monitoring events
  • Parametric and non-parametric tests
  • Assessed significance in observed trends between current and baseline surveys

 Coordinate directly with State and Federal Agencies to employ approved standard operation procedures for monitoring methodology

  • Followed the 2014 Revised Biological Monitoring Plan
  • Prior to survey, conference with FDEP to ensure adherence to approved methodology
  • Followed the “Standard Operation Procedures For Nearshore Hardbottom Monitoring

Of Beach Nourishment Projects”: methods for data collection, and report/figure generation  Used modern survey quality geographic positioning systems in combination with navigational software for plotting and development of GIS habitat maps (industry standard)  Comprehensive Research, Inventory, and Statistical Comparison of historical monitoring data

Port Everglades Navigation Improvement Project (PRENIP) – 2016 to present

 Collecting baseline information for environmental resource permitting for dredging/port improvement  Two different monitoring protocols: ESA and Recon, used to collect baseline data on hardbottom habitat (nearshore to offshore habitats, various reef habitats)

  • ESA- specifically addressing ESA (Endangered Species Act) Listed

Species: Acropora palmata, Acropora cervicornis, Dendrogyra cylindrus, Mycetophyllia ferox, Orbicella annularis, Orbicella faveolata, and Orbicella franksi. Colony measurements, points, Species ID, location along transect.

  • Reconnaissance
  • video collection to provide benthic cover data, collected at a fixed

height and speed

  • Belt-transect: collecting data on all scleractinian (hard) corals

(species ID, maximum size, count, photos, location), and count and size class data for Xestospongia muta (Giant barrel sponges)

  • Quadrat data: octocoral (ID to genus level, maximum

measurement, count), sponge (morphotype, size class, count), maximum relief, maximum sediment depth and percent cover data collected at each quadrat location (14 functional groups)

  • Collect Hydrodynamic Current and Waves Data to support

nearshore sediment transport modeling

Coral Collection, Handling, Relocation and Nursery Development – 2009 to present

 Pinnacle is recognized by the National Oceanic and Atmospheric Administration (NOAA) and the Florida Keys National Marine Sanctuary (FKNMS) as leaders in coral reef damage assessment, reef rehabilitation, and coral transplantation.  Experience producing coral relocation plans, and obtaining Special Activities Licenses from Florida Fish and Wildlife Conservation Commission (FWC) for coral relocation activities.  Collectively, the team at Pinnacle has reattached more than 10,000 corals in the last 10 years  Multitude of past and ongoing projects that involve: coral relocation and monitoring, coral damage assessment, restoration, and monitoring, collection of baseline coral data, and development of effective mitigation planning for successful project permitting.
