A Quick Guide to Southeast Florida's Coral Reefs
A Quick Guide to Southeast Florida’s Coral Reefs DAVID GILLIAM NATIONAL CORAL REEF INSTITUTE NOVA SOUTHEASTERN UNIVERSITY Spring 2013 Prepared by the Land-based Sources of Pollution Technical Advisory Committee (TAC) of the Southeast Florida Coral Reef Initiative (SEFCRI) BRIAN WALKER NATIONAL CORAL REEF INSTITUTE, NOVA SOUTHEASTERN Southeast Florida’s coral-rich communities are more valuable than UNIVERSITY the Spanish treasures that sank nearby. Like the lost treasures, these amazing reefs lie just a few hundred yards off the shores of Martin, Palm Beach, Broward and Miami-Dade Counties where more than one-third of Florida’s 19 million residents live. Fishing, diving, and boating help attract millions of visitors to southeast Florida each year (30 million in 2008/2009). Reef-related expen- ditures generate $5.7 billion annually in income and sales, and support more than 61,000 local jobs. Such immense recreational activity, coupled with the pressures of coastal development, inland agriculture, and robust cruise and commercial shipping industries, threaten the very survival of our reefs. With your help, reefs will be protected from local stresses and future generations will be able to enjoy their beauty and economic benefits. Coral reefs are highly diverse and productive, yet surprisingly fragile, ecosystems. They are built by living creatures that require clean, clear seawater to settle, mature and reproduce. Reefs provide safe havens for spectacular forms of marine life. Unfortunately, reefs are vulnerable to impacts on scales ranging from local and regional to global. Global threats to reefs have increased along with expanding ART SEITZ human populations and industrialization. Now, warming seawater temperatures and changing ocean chemistry from carbon dioxide emitted by the burning of fossil fuels and deforestation are also starting to imperil corals. -

Basic Concepts in Oceanography
Chapter 1 XA0101461 BASIC CONCEPTS IN OCEANOGRAPHY L.F. SMALL College of Oceanic and Atmospheric Sciences, Oregon State University, Corvallis, Oregon, United States of America Abstract Basic concepts in oceanography include major wind patterns that drive ocean currents, and the effects that the earth's rotation, positions of land masses, and temperature and salinity have on oceanic circulation and hence global distribution of radioactivity. Special attention is given to coastal and near-coastal processes such as upwelling, tidal effects, and small-scale processes, as radionuclide distributions are currently most associated with coastal regions. 1.1. INTRODUCTION Introductory information on ocean currents, on ocean and coastal processes, and on major systems that drive the ocean currents are important to an understanding of the temporal and spatial distributions of radionuclides in the world ocean. 1.2. GLOBAL PROCESSES 1.2.1 Global Wind Patterns and Ocean Currents The wind systems that drive aerosols and atmospheric radioactivity around the globe eventually deposit a lot of those materials in the oceans or in rivers. The winds also are largely responsible for driving the surface circulation of the world ocean, and thus help redistribute materials over the ocean's surface. The major wind systems are the Trade Winds in equatorial latitudes, and the Westerly Wind Systems that drive circulation in the north and south temperate and sub-polar regions (Fig. 1). It is no surprise that major circulations of surface currents have basically the same patterns as the winds that drive them (Fig. 2). Note that the Trade Wind System drives an Equatorial Current-Countercurrent system, for example. -
CITY of MIAMI BEACH DUNE MANAGEMENT PLAN January 2016
CITY OF MIAMI BEACH DUNE MANAGEMENT PLAN January 2016 Prepared by: CITY OF MIAMI BEACH COASTAL MANAGEMENT 1700 Convention Center Drive AND CONSULTING Miami Beach, Florida 33139 7611 Lawrence Road Boynton Beach, Florida 33436 I. STATEMENT OF PURPOSE Coastal dunes are habitat for wildlife and support a high biodiversity of flora and fauna. They also keep beaches healthy by accreting sand and minimizing beach erosion rates. The dunes protect coastal infrastructure and upland properties from storm damage by blocking storm surge and absorbing wave energy. Therefore, a healthy dune system is an invaluable asset to coastal communities like Miami Beach. The purpose of the City of Miami Beach Dune Management Plan (“the Plan”) is to outline the framework and specifications that the City will use to foster and maintain a healthy, stable, and natural dune system that is appropriate for its location and reduces public safety and maintenance concerns. The Plan shall guide the City’s efforts in managing the urban, man-made dune as close to a natural system as possible and ensuring the dune provides storm protection, erosion control, and a biologically-rich habitat for local species. II. OBJECTIVES This plan was developed collaboratively with local government and community stakeholders, as well as local experts to meet the following primary objectives: 1. Reduce to the maximum extent possible the presence of invasive, non-native pest plant species within the dune system. Non-native species compete with and overwhelm more stable native dune plants, thereby threatening the stability and biodiversity of the dune system. Reducing the presence of aggressive, non-native vegetation preserves and promotes the structural integrity and biodiversity of the dune. -

Rip Current Observations Via Marine Radar
Rip Current Observations via Marine Radar Merrick C. Haller, M.ASCE1; David Honegger2; and Patricio A. Catalan3 Abstract: New remote sensing observations that demonstrate the presence of rip current plumes in X-band radar images are presented. The observations collected on the Outer Banks (Duck, North Carolina) show a regular sequence of low-tide, low-energy, morphologically driven rip currents over a 10-day period. The remote sensing data were corroborated by in situ current measurements that showed depth-averaged rip current velocities were 20e40 cm=s whereas significant wave heights were Hs 5 0:5e1 m. Somewhat surprisingly, these low-energy rips have a surface signature that sometimes extends several surf zone widths from shore and persists for periods of several hours, which is in contrast with recent rip current observations obtained with Lagrangian drifters. These remote sensing observations provide a more synoptic picture of the rip current flow field and allow the identification of several rip events that were not captured by the in situ sensors and times of alongshore deflection of the rip flow outside the surf zone. These data also contain a rip outbreak event where four separate rips were imaged over a 1-km stretch of coast. For potential comparisons of the rip current signature across other radar platforms, an example of a simply calibrated radar image is also given. Finally, in situ observations of the vertical structure of the rip current flow are given, and a threshold offshore wind stress (.0:02 m=s2)isfoundto preclude the rip current imaging.

A Lifeguard's Beach Safety Tips
A Lifeguard’s Beach Safety Tips by Sgt. Ed Fisher Special to the Dispatch The writer is a 17-year veteran of the Beach patrol. In the off-season, he is an elementary school teacher in Montgomery County. The OCBP consist of over 200 men and women dedicated to ocean rescue and maintaining a safe and orderly environment on Ocean City’s beach. The Sure Rescue Technicians guard the beach seven days a week from 10 a.m. – 5:30 p.m. Studying the waves helps safety September 12, 2008 The Dispatch/Maryland Coast Dispatch Recently a kite surfer tried surfing in a hurricane and ended up getting blown into the side of a building. An accident like this does not happen because of bad luck. An accident like this happens because of poor decision making, not knowing your sport, and not respecting the elements. I mean is it really surprising that a kite that was flying in a hurricane got out of control? The idea here is that everyone entering the surf should have more common sense than this and take some basic precautions. The first precaution begins on the beach. People should spend at least 15 minutes on the beach surveying the conditions. Often people come out to the beach and see a calm ocean. As soon as they attempt to swim they find themselves confronted with a dangerous set of waves or strong currents they were not aware of. Be sure to know what the conditions are before entering the water. The daily conditions of the ocean are governed by the swell direction, wind velocity, and ocean bottom. -

What Are Rip Currents? Types of Rips Are Rips Dangerous
What are Rip Currents? Rips are strong, narrow currents that flow from the shoreline seaward past the breaking waves. They exist as a way of getting water carried to the beach by breaking waves back out to sea and are usually confined to deeper channels between shallow sand bars. The bigger the waves, the stronger the rip. Think of them as "rivers of the sea". Types of Rips • Low energy rips are the most common and occur when waves are smaller or haven't changed in a while. They are usually fixed in place and sit in channels between sand bars and don't move much. • High energy or flash rips are bigger and occur when waves have increased suddenly, or during a storm. They tend to move around a bit and flow faster. • Headland and fixed rips are often permanent and occur next to headlands and structures such as groynes and jetties. Low Energy Rip High Energy Rip Are Rips Dangerous? Rips are only dangerous if you don't understand what they are and you are not a good swimmer. They can carry you more than 100 m offshore in less than a minute and are the major cause of surf drownings and rescues in Australia. However, surfers use rips to their advantage to help them swim out through the surf quickly. Page1of2 © 2007 Dr R Brander continued Spotting a Rip Since rips often sit in deeper channels between shallow sand bars, always spend 5-10 minutes looking at the surf zone for consistent darker and "calmer" areas of water that extend offshore between the breaking waves. -
