Assessment and Catalogue of Puerto Rican Mooring Buoys WORCESTER POLYTECHNIC INSTITUTE May 5, 2009 Assessment and Catalogue of Puerto Rican Mooring Buoys WORCESTER POLYTECHNIC INSTITUTE May 5, 2009 By Greg Coffey Eric Greer Ryan LaSante Brittany McNally Project Liaison: Dr. Craig Lilyestrom, Mr. Carlos Matos Project Advisors: Professor Karen Lemone and Professor Ingrid Shockey ABSTRACT The Department of Natural and Environmental Resources of Puerto Rico has installed over 270 mooring buoys in seagrass, coral, and mangrove regions with the anticipation that they will curb boating damage and allow these natural environments to recover. To streamline buoy management, our group constructed a Geographic Information System database. This contains data we gathered at each buoy concerning its exact GPS location, condition, the recovery of the environment it is protecting, and observations of boating trends within the region. ii ACKNOWLEDGEMENTS Throughout the course of this project there have been many helpful individuals who have taken time from their busy lives to contribute to the success of this project. We would like to thank them for their contributions. To Craig Lilyestrom for his wealth of information and coordination of our entire project. To Carlos Matos for his exceptional aid with fieldwork, and continuous support with all aspects of our project. To Edwin and Maribel Rodriguez for the sharing of their photography, and help throughout our project. To the Oficina de Informática: Nora Alvarez, Victor Cuadrado Landrau, and Alberto Colón for their help with developing the GIS Database. To the Coral Rangers for their assistance with aquatic transportation. To our fellow colleagues from WPI: Kevin Vayda, Dan Cafferty, and Jason Carmichael for their willingness to share their survey results. iii AUTHORSHIP We, as a group, have researched and written this report. All sections of this paper were written through our combined efforts. We have all agreed upon this. iv TABLE OF CONTENTS ABSTRACT

Costs of solar thermal collectors employed in stand-alone power plants are noticeably higher than more mature technologies one. A suitable alternative to exploit the solar thermal energy is the integration of solar collectors in already existing fossil-fuelled power plants; in this way, the investment cost of the power block is avoided and solar thermal energy is converted at higher efficiency. The present thesis work presents the analysis of several layouts of Integrated Solar Combined Cycle (ISCCs) in terms of nominal and annual performances and costs of the electricity. In the first part of the work, an analysis of the existing integrated plants and the state of the art of the ISCC technology have been presented. Advantages and disadvantages of the integration of solar collectors in different kind of power plants have been pointed out and a literature review of present studies about ISCCs has been made. Several commercial solar collectors have been analysed and a thermal model has been built to estimate the heat losses of collectors receiver.

October l r3, ~1980 l,' ~ ".,/ ',. .. : ~ - . ~~ -~ INTRODUCTION Since 1956 Government laboratories have been meeting to exchange ideas on hydraulic laboratory techniques and instrumentation. These meetings have been held at about 2-year intervals. This seminar was the eleventh of the series and represented a radical departure from the traditional participants. For the first time, university and private laboratories were invited to attend. This outside participation added additional spice to the meetings. To maximize the exchange of information, participation was limited by invitation to the major laboratories in the United States. A strong emphasis was placed upon discussions of what did not work as well as what was successful. In addition to the scheduled talks, an impromptu session was held to discuss "who knows about ?" One of the highlights of the seminar was a panel discussion following the banquet concerning the management of research from the Government, private industry, and university viewpoints. Surprisingly, there were far more similarities than differences between the three types of laboratories. The format of this report is an overall summary of each session, comments on each paper, followed by the papers. It was felt that this format promoted the greatest amount of candid response from the participants. Seminar Agenda Organizing Committee Danny L. King E. J. Carlson Henry T. Falvey Thomas J.

  • Commonwealth Marine Reserves Review
    Chapter 3 Assessments of new scientific information to support Commonwealth marine reserve zoning and management decisions The Expert Scientific Panel (ESP) terms of reference included providing advice on options for zoning and allowed uses consistent with the Goals and principles for the establishment of the National Representative System of Marine Protected Areas in Commonwealth waters (the Goals and Principles). Noting the extensive scientific process that underpinned the design of the Commonwealth marine reserves (CMRs) proclaimed in 2012, as outlined in chapter 2, and mindful of work of the Bioregional Advisory Panel (BAP) to identify possible new zoning boundaries for the CMR estate, the ESP focused its work on this term of reference on new science directly relevant to the needs of the BAP. The BAP referred a number of matters to the ESP for advice. These matters related to areas of contention identified through the BAP consultation process. They are listed in table 3.1 and are addressed in this chapter. The associated findings were communicated to the BAP for consideration in formulating recommendations on zoning options. Broadly, these matters related to: • concerns about the applicability of Fishing Gear Risk Assessment (FGRA) findings to certain gear types in certain areas of the CMR estate (section 3.1) • concerns about the impact of recreational fishing (section 3.2) • concerns about the effectiveness of different zone types (section 3.3) • the need to have up-to-date scientific information for particular marine features and particular CMRs (sections 3.4 and 3.5). Table 3.1 Issues referred by the Bioregional Advisory Panel to the Expert Scientific Panel for advice Advice request CMR and/or network to Relevant which the request related section of ESP report Evaluate the process used to determine fishing gear risk for Estate-wide 2.3.5 CMRs.

  • Connectivity Across the Caribbean
    Connectivity across the Caribbean Sea: DNA Barcoding and Morphology Unite an Enigmatic Fish Larva from the Florida Straits with a New Species of Sea Bass from Deep Reefs off Curac¸ao Carole C. Baldwin*, G. David Johnson Department of Vertebrate Zoology, National Museum of Natural History, Smithsonian Institution, Washington D. C., United States of America Abstract Integrative taxonomy, in which multiple disciplines are combined to address questions related to biological species diversity, is a valuable tool for identifying pelagic marine fish larvae and recognizing the existence of new fish species. Here we combine data from DNA barcoding, comparative morphology, and analysis of color patterns to identify an unusual fish larva from the Florida Straits and demonstrate that it is the pelagic larval phase of a previously undescribed species of Liopropoma sea bass from deep reefs off Curac¸ao, southern Caribbean. The larva is unique among larvae of the teleost family Serranidae, Tribe Liopropomini, in having seven elongate dorsal-fin spines. Adults of the new species are similar to the golden bass, Liopropoma aberrans, with which they have been confused, but they are distinct genetically and morphologically. The new species differs from all other western Atlantic liopropomins in having IX, 11 dorsal-fin rays and in having a unique color pattern–most notably the predominance of yellow pigment on the dorsal portion of the trunk, a pale to white body ventrally, and yellow spots scattered across both the dorsal and ventral portions of the trunk. Exploration of deep reefs to 300 m using a manned submersible off Curac¸ao is resulting in the discovery of numerous new fish species, improving our genetic databases, and greatly enhancing our understanding of deep-reef fish diversity in the southern Caribbean.
