    Description: Background:The rising temperature of the world’s oceans has become a major threat to coral reefs globally as the severityand frequency of mass coral bleaching and mortality events increase. In 2005, high ocean temperatures in the tropicalAtlantic and Caribbean resulted in the most severe bleaching event ever recorded in the basin.Methodology/Principal Findings:Satellite-based tools provided warnings for coral reef managers and scientists, guiding both the timing and location of researchers’ field observations as anomalously warm conditions developed and spread across the greater Caribbean region from June to October 2005. Field surveys of bleaching and mortality exceeded prior efforts in detail and extent, and provided a new standard for documenting the effects of bleaching and for testing nowcast and forecast products. Collaborators from 22 countries undertook the most comprehensive documentation of basin-scale bleaching to date and found that over 80% of corals bleached and over 40% died at many sites. The most severe bleaching coincided with waters nearest a western Atlantic warm pool that was centered off the northern end of the Lesser Antilles.Conclusions/Significance:Thermal stress during the 2005 event exceeded any observed from the Caribbean in the prior 20 years, and regionally-averaged temperatures were the warmest in over 150 years. Comparison of satellite data against field surveys demonstrated a significant predictive relationship between accumulated heat stress (measured using NOAA CoralReef Watch’s Degree Heating Weeks) and bleaching intensity. This severe, widespread bleaching and mortality willundoubtedly have long-term consequences for reef ecosystems and suggests a troubled future for tropical marine ecosystems under a warming climate

    Description: A Fisheries Forum in Cuba brought together stakeholders from coastal communities to examine opportunities and challenges to make fisheries more sustainable. Fishermen from across Cuba gathered for the first time in September 2018 at the Fisheries Forum called Encuentro Pesquero. For three days, 55 stakeholders, including 21 fishermen from 10 coastal communities, joined heads to diagnose the status of fish populations and priorities for their management across Cuba’s four fishing zones. They examined opportunities and challenges for sustainable fisheries and developed a shared vision for the future.

    Description: In addition to providing vital ecological services, coastal areas of North Carolina provide prized areas for habitation,recreation, and commercial fisheries. However, from a management perspective, the coasts of North Carolina arehighly variable and complex. In-water constituents such as nutrients, suspended sediments, and chlorophyll aconcentration can vary significantly over a broad spectrum of time and space scales. Rapid growth and land-usechange continue to exert pressure on coastal lands. Coastal environments are also very vulnerable to short-term (e.g.,hurricanes) and long-term (e.g., sea-level rise) natural changes that can result in significant loss of life, economic loss, or changes in coastal ecosystem functioning. Hence, the dynamic nature, effects of human-induced change over time, and vulnerability of coastal areas make it difficult to effectively monitor and manage these important state and national resources using traditional data collection technologies such as discrete monitoring stations and field surveys. In general, these approaches provide only a sparse network of data over limited time and space scales and generally are expensive and labor-intensive.Products derived from spectral images obtained by remote sensing instruments provide a unique vantage point fromwhich to examine the dynamic nature of coastal environments. A primary advantage of remote sensing is that the altitude of observation provides a large-scale synoptic view relative to traditional field measurements. Equallyimportant, the use of remote sensing for a broad range of research and environmental applications is now commondue to major advances in data availability, data transfer, and computer technologies. To facilitate the widespread useof remote sensing products in North Carolina, the UNC Coastal Studies Institute (UNC-CSI) is developing thecapability to acquire, process, and analyze remotely sensed data from several remote sensing instruments. Inparticular, UNC-CSI is developing regional remote sensing algorithms to examine the mobilization, transport,transformation, and fate of materials between coupled terrestrial and coastal ocean systems. To illustrate this work, we present the basic principles of remote sensing of coastal waters in the context of deriving information thatsupports efficient and effective management of coastal resources.

    Description: Congress established a legal imperative to restore the quality of our surface waters when it enacted the Clean Water Act in 1972. The act requires that existing uses of coastal waters such as swimming and shellfishing be protected and restored. Enforcement of this mandate is frequently measured in terms of the ability to swim and harvest shellfish in tidal creeks, rivers, sounds, bays, and ocean beaches. Public-health agencies carry out comprehensive water-quality sampling programs to check for bacteria contamination in coastal areas where swimming andshellfishing occur. Advisories that restrict swimming and shellfishing are issued when sampling indicates thatbacteria concentrations exceed federal health standards. These actions place these coastal waters on the U.S.Environmental Protection Agencies’ (EPA) list of impaired waters, an action that triggers a federal mandate toprepare a Total Maximum Daily Load (TMDL) analysis that should result in management plans that will restoredegraded waters to their designated uses.When coastal waters become polluted, most people think that improper sewage treatment is to blame. Water-qualitystudies conducted over the past several decades have shown that improper sewage treatment is a relatively minorsource of this impairment. In states like North Carolina, it is estimated that about 80 percent of the pollutionflowing into coastal waters is carried there by contaminated surface runoff. Studies show this runoff is the result of significant hydrologic modifications of the natural coastal landscape.There was virtually no surface runoff occurring when the coastal landscape was natural in places such as NorthCarolina. Most rainfall soaked into the ground, evaporated, or was used by vegetation. Surface runoff is largely anartificial condition that is created when land uses harden and drain the landscape surfaces. Roofs, parking lots,roads, fields, and even yards all result in dramatic changes in the natural hydrology of these coastal lands, andgenerate huge amounts of runoff that flow over the land’s surface into nearby waterways.

    Description: The largely sedentary behavior of many fishes on coral reefs is well established. Information on the movement behavior of individual fish, over fine temporal and spatialscales, however, continues to be limited. It is precisely this type of information that is critical for evaluating the success of marine reserves designed for the conservation and/or management of vagile fishes. In this pilot study we surgically-tagged eight hogfish(Lachnolaimus maximus Walbaum 1792) with coded-acoustic transmitters inside the Conch Reef Research Only Area (a no-take marine reserve) in the northern Florida KeysNational Marine Sanctuary. Our primary objective was to characterize the movement of L. maximus across Conch Reef in the vicinity of the reserve. All fish were captured,surgically-tagged and released in situ during a saturation mission to the Aquarius Undersea Laboratory, which is located in the center of the reserve. Movement of taggedL. maximus was recorded for up to 95 days by three acoustic receivers deployed on the seafloor. Results showed clear diel patterns in L. maximus activity and regular movementamong the receivers was recorded for seven of the eight tagged fish. Fidelity of tagged fish to the area of release was high when calculated at the scale of days, while within-day fidelity was comparatively low when calculated at the scale of hours. While the number of fish departures from the array also varied, the majority of departures for seven of the eight fish did not exceed 1-hr (with the exception of one 47-day departure), suggesting that when departures occurred, the fish did not travel far. Future efforts will significantly expand the number of receivers at Conch Reef such that fish movement behavior relative to the reserve boundaries can be quantified with increased temporal and spatial resolution.
