These two monitoring programs are inextricably related; population and community changes that result from the Sanctuary’s network of fully protected marine zones occur in the context of large-scale environmental characteristics measured by the water quality, seagrass, and coral reef evaluation and monitoring projects of the WQPP. This year we have added a set of summary reports on socioeconomic research projects, and continue to present findings of partnership projects with NOAA National Centers for Coastal Ocean Science. After presenting reports on two long-spined urchin (Diadema antillarum) restoration projects, we conclude with lists of permitted research projects for the years 2002 and 2003. We thank the large group of investigators working in the Florida Keys National Marine Sanctuary for designing projects and collecting the ecological and socioeconomic data we need to evaluate the condition of the Sanctuary’s resources and how the ecosystem as well as human uses and perceptions respond to management actions.

2 October 2006 Executive Summary Circulation and Exchange of Florida Bay and South Florida Coastal Waters The coastal ecosystem of South Florida is comprised of distinct marine environments. Circulation of surface waters and exchange processes, which respond to both local and regional forcings, interconnect different coastal environments. In addition, re-circulating current systems within the South Florida coastal ecosystem such as the Tortugas Gyre contribute to retention of locally spawned larvae. Variability in salinity, chlorophyll, and light transmittance occurs on a wide range of temporal and spatial scales, in response to both natural forcing, such as seasonal precipitation and evaporation and interannual “El Niño” climate signals, and anthropogenic forcing, such as water management practices in south Florida. The full time series of surface property maps are posted at www.aoml.noaa.gov/sfp. Regional surface circulation patterns, shown by satellite-tracked surface drifters, respond to large-scale forcing such as wind variability and sea level slopes. Recent patterns include slow flow from near the mouth of the Shark River to the Lower Keys, rapid flow from the Tortugas to the shelf of the Carolinas, and flow from the Tortugas around the Tortugas Gyre and out of the Florida Straits. The Southwest Florida Shelf and the Atlantic side of the Florida Keys coastal zone are directly connected by passages between the islands of the Middle and Lower Keys. Movement of water between these regions depends on a combination of local wind-forced currents and gravity- driven transports through the passages, produced by cross-Key sea level differences on time scales of several days to weeks, which arise because of differences in physical characteristics (shape, orientation, and depth) of the shelf on either side of the Keys. A southeastward mean flow transports water from western Florida Bay, which undergoes large variations in water quality, to the reef tract. Adequate sampling of oceanographic events requires both the capability of near real-time recognition of these events, and the flexibility to rapidly stage targeted field sampling. Capacity to respond to events is increasing, as demonstrated by investigations of the 2002 “blackwater” event and a 2003 entrainment of Mississippi River water to the Tortugas.

  • Mollusks Background the Florida Keys Marine Ecosystem Supports a Diverse Fauna of Mollusks Belonging to Several Orders
    2010 Quick Look Report: Miller et al. VII. Abundance and Size of Selected Mollusks Background The Florida Keys marine ecosystem supports a diverse fauna of mollusks belonging to several orders. Opisthobranch mollusks, for example, are represented by at least 30 species of sea slugs (Sacoglossa) and 23 species of nudibranchs (Nudibranchia) (Clark and DeFreese 1987; Levy et al. 1996), including at least three endemic species (Clark 1994). Data on the status and trends of mollusk populations and habitat utilization patterns in the Florida Keys, with the exception of queen conch (Strombus gigas), are generally limited (Marcus 1960; Jensen and Clark 1983; Clark and DeFreese 1987), as most previous studies have been qualitative in nature (Clark 1994; Trowbridge 2002). Clark (1994) noted a declining population trend for the lettuce sea slug, Elysia (Tridachia) crispata Mörch (see cladistic analyses in Gosliner 1995; Jensen 1996) in southern Florida, based upon qualitative comparisons of occurrence and population densities between 1969-80 and 1987-93. About 50% of the nearshore populations assessed by Clark (1994) nearly 17 years ago were declining due to habitat destruction, siltation, eutrophication, and over- collection, particularly evident in nearshore habitats. Since 2001, we have conducted intermittent surveys of various gastropod mollusk species in conjunction with assessments of other benthic variables. For example, we encountered unusually high densities of lettuce sea slugs among 63 shallow fore reef sites during June-September 2001. While sacoglossans are not particularly rare in many shallow-water marine habitats where densities correlate with algal biomass (Clarke and DeFreese 1987), our observations offshore were considered unusual because fleshy algal cover tends to be relatively low (Chiappone et al.

  • Variable Holocene Deformation Above a Shallow Subduction Zone Extremely Close to the Trench
    ARTICLE Received 24 Nov 2014 | Accepted 22 May 2015 | Published 30 Jun 2015 DOI: 10.1038/ncomms8607 OPEN Variable Holocene deformation above a shallow subduction zone extremely close to the trench Kaustubh Thirumalai1,2, Frederick W. Taylor1, Chuan-Chou Shen3, Luc L. Lavier1,2, Cliff Frohlich1, Laura M. Wallace1, Chung-Che Wu3, Hailong Sun3,4 & Alison K. Papabatu5 Histories of vertical crustal motions at convergent margins offer fundamental insights into the relationship between interplate slip and permanent deformation. Moreover, past abrupt motions are proxies for potential tsunamigenic earthquakes and benefit hazard assessment. Well-dated records are required to understand the relationship between past earthquakes and Holocene vertical deformation. Here we measure elevations and 230Th ages of in situ corals raised above the sea level in the western Solomon Islands to build an uplift event history overlying the seismogenic zone, extremely close to the trench (4–40 km). We find marked spatiotemporal heterogeneity in uplift from mid-Holocene to present: some areas accrue more permanent uplift than others. Thus, uplift imposed during the 1 April 2007 Mw 8.1 event may be retained in some locations but removed in others before the next megathrust rupture. This variability suggests significant changes in strain accumulation and the interplate thrust process from one event to the next. 1 Institute for Geophysics, Jackson School of Geosciences, University of Texas at Austin, J.

Principal Investigators: William C. Sharp and Kerry E. Maxwell Florida Fish & Wildlife Conservation Commission Fish & Wildlife Research Institute 2796 Overseas Hwy., Suite 119 Marathon FL 33050 Project Period: 15 January 2018 – 30 June 2018 Reporting Period: 21 April 2018 – 15 June 2018 Background: Disease is recognized as a major cause of the progressive decline in reef-building corals that has contributed to the general decline in coral reef ecosystems worldwide (Jackson et al. 2014; Hughes et al. 2017). The first reports of coral disease in the Florida Keys emerged in the 1970’s and numerous diseases have been documented with increasing frequency (e.g., Porter et al., 2001). Presently, the Florida Reef Tract (FRT) is experiencing one of the most widespread and virulent disease outbreaks on record. This outbreak has resulted in the mortality of thousands of colonies of at least 20 species of scleractinian coral, including primary reef builders and species listed as Threatened under the Endangered Species Act.
