With 1,357 miles of coastline, involvement by 34 different counties, and over 2,500 artificial reefs deployed to date, Florida manages one of the most diverse and most active artificial reef programs in the United States. Because artificial reef development in Florida works with, and depends upon, a network of local partners, inter-county coordina- tion and communication is critical to ensure successful implementation of statewide strate- gic objectives for artificial reef development. This Summit occurs every 3 to 5 years and provides the format for local partners to meet and exchange information. It is a critical opportunity for the Florida Fish and Wildlife Con- In Memoriam servation Commission Artificial Reef Program and Florida Sea Grant to disperse high-quality information, experience and program goals and objectives directly with all of Florida’s The 2010 Artificial Reef Summit is dedicated to the memory of Chris Koepfer, the long-time Lee County Arti- artificial reef stakeholders. ficial Reef Coordinator who passed away in 2009.

Box 4970 Jacksonville, Florida 32232-0019 Ref.: U.S. Army Corps of Engineers Jacksonville District’s Programmatic Biological Opinion (JAXBO) Dear Mr. Kinard: Enclosed is the National Marine Fisheries Service’s (NMFS’s) Programmatic Biological Opinion (Opinion) based on our review of the impacts associated with the U.S. Army Corps of Engineers (USACE’s) Jacksonville District’s authorization of 10 categories of minor in-water activities within Florida and the U.S. Caribbean (Puerto Rico and the U.S. Virgin Islands). The Opinion analyzes the effects from 10 categories of minor in-water activities occurring in Florida and the U.S. Caribbean on sea turtles (loggerhead, leatherback, Kemp’s ridley, hawksbill, and green); smalitooth sawfish; Nassau grouper; scalloped hammerhead shark, Johnson’s seagrass; sturgeon (Gulf, shortnose, and Atlantic); corals (elkhom, staghorn, boulder star, mountainous star, lobed star, rough cactus, and pillar); whales (North Atlantic right whale, sei, blue, fin, and sperm); and designated critical habitat for Johnson’s seagrass; smalltooth sawfish; sturgeon (Gulf and Atlantic); sea turtles (green, hawksbill, leatherback, loggerhead); North Atlantic right whale; and elkhorn and staghorn corals in accordance with Section 7 of the Endangered Species Act. We also analyzed effects on the proposed Bryde’s whale. -
A Numerical Assessment of Artificial Reef Pass Wave-Induced Currents As a Renewable Energy Source

The overall idea is to mimic the functioning of natural reef–lagoon systems in which the cross-reef pressure gradient induced by wave breaking is able to drive an outward flow through the pass. The objective is to estimate the feasibility of a positive energy breakwater, combining the usual wave-sheltering function of immersed breakwater together with the production of renewable energy by turbines. A series of numerical simulations is performed using a depth-averaged model to understand the effects of each geometrical reef parameter on the reef–lagoon hydrodynamics. A synthetic wave and tide climate is then imposed to estimate the potential power production. An annual production between 50 and 70 MWh is estimated. Keywords: artificial reef; positive energy breakwater; numerical simulation; turbines 1. Introduction Low-lying nearshore areas host a significant and increasing population. Under the combined actions of sea level rise [1], modified storm patterns [2], and increasing urbanization, these regions will face growing risks of submersion, inundation, and erosion [3–6]. -

Disneynature DOLPHIN REEF Educator's Guide
Educator’s Guide Grades 2-6 n DOLPHIN REEF, Disneynature dives under the sea Ito frolic with some of the planet’s most engaging animals: dolphins. Echo is a young bottlenose dolphin who can’t quite decide if it’s time to grow up and take on new responsibilities—or give in to his silly side and just have fun. Dolphin society is tricky, and the coral reef that Echo and his family call home depends on all of its inhabitants to keep it healthy. But with humpback whales, orcas, sea turtles and cuttlefish seemingly begging for his attention, Echo has a tough time resisting all that the ocean has to offer. The Disneynature DOLPHIN REEF Educator’s Guide includes multiple standards-aligned lessons and activities targeted to grades 2 through 6. The guide introduces students to a variety of topics, including: • Animal Behavior • Biodiversity • Culture and the Arts and Natural History • Earth’s Systems • Making a Positive Difference • Habitat and Ecosystems for Wildlife Worldwide Educator’s Guide Objectives 3 Increase students’ 3 Enhance students’ viewing 3 Promote life-long 3 Empower you and your knowledge of the of the Disneynature film conservation values students to create positive amazing animals and DOLPHIN REEF and and STEAM-based skills changes for wildlife in habitats of Earth’s oceans inspire an appreciation through outdoor natural your school, community through interactive, for the wildlife and wild exploration and discovery. and world. interdisciplinary and places featured in the film. inquiry-based lessons.
