SBOO plume mapping 2. Tijuana River plume mapping 3. Boat survey-mapping of land based plume 4. Continuous flow rate and loading of the Tijuana River 5. Ocean moorings at key areas 6. Mapping of ocean currents using CODAR and improved data handling 7. The development of indicator studies to support source identification 8. Identification of spatial patterns Significant variability exists in the water quality of the region. SDCOOS goals to explain how the environment impacts this variability.

  • ADM Issue 4 Finnished
    DEMA 2000 marks one year since the sale of DeepTech by my two ex-business partners. Being the original founder of DeepTech, the news of its sale without my knowledge or approval kinda, well lets say: rubbed me the wrong way. Not only was I concerned about all the years and thousands of hours of work I put into DeepTech but also about the subscribers who had paid their money for a subscription and now would not receive what they shelled out their hard earned cash for. My reputation not only as a publisher but also as a respected diver was immediately at stake. Knocked back to step one after all these years was a hard blow but also a blessing in disguise. When I started DeepTech I had no connections, no advertisers and very little money. After 4 years in circulation I had thousands of connections, good rapport with my advertisers, and a little more money to start over from square one. Advanced Diver Magazine was born with no business part- ners, many of the same advertisers and a data base of good subscribers available. One year has passed and the small staff at ADM has delivered what we had prom- ised. An on-time, high quality, fully illustrated dive magazine like no other. Designed with a good balance of text, illustrations, photos and less than 20% advertising. ADM will continue into the new millen- nium providing what we promised our subscribers with the quality and graphic design that I expect as the founder and publisher. After all, my reputation is at stake.

  • Introduction
    Introduction The best way to understand and appreciate the natural world that sur- rounds us may be to explore beneath its surface—not by digging, which destroys the very systems we seek to examine, but by looking underwater, which we can do with little or no disruption of the processes we observe. Birth and death, growth and decline, the interaction of plants, animals and minerals, of predators and prey—in short, everything that happens in the familiar environment aboveground also happens below the waves. Because water is transparent, these phenomena should be easier to ob- serve there; yet the environment is so profoundly alien to human beings that venturing down even 40 or 50 feet is the closest almost any of us will come to visiting another planet. A person needn’t be a scuba diver or a snorkeler to explore the fascinat- ing complexity of life beneath the surface. You don’t even have to be able to swim. I prefer to visit this engagingly exotic world in person, listening to the gentle bubbles of my exhalations as I glide lazily along, enveloped in warm liquid. (As a diver, I’m something of a wuss. I never was one for cold-water diving and have a decided preference for the tropics.) But I have become increasingly amazed at the quality and detail captured by the world’s great underwater cinematographers and even by enthusiastic graduate students. The latter’s camera work may waver, but their obvious excitement and their exclamations of “Awesome grouper!” and the like make up for the home-movie visual quality.

  • Below the Mesophotic C
    www.nature.com/scientificreports OPEN Below the Mesophotic C. C. Baldwin1, L. Tornabene2 & D. R. Robertson3 Mesophotic coral ecosystems, which occur at depths of ~40 to 150 m, have received recent scientifc attention as potential refugia for organisms inhabiting deteriorating shallow reefs. These ecosystems merit research in their own right, as they harbor both depth-generalist species and a distinctive reef-fsh Received: 31 August 2017 fauna. Reef ecosystems just below the mesophotic are globally underexplored, and the scant recent literature that mentions them often suggests that mesophotic ecosystems transition directly into Accepted: 12 February 2018 those of the deep sea. Through submersible-based surveys in the Caribbean Sea, we amassed the most Published: xx xx xxxx extensive database to date on reef-fsh diversity between ~40 and 309 m at any single tropical location. Our data reveal a unique reef-fsh assemblage living between ~130 and 309 m that, while taxonomically distinct from shallower faunas, shares strong evolutionary afnities with them. Lacking an existing name for this reef-faunal zone immediately below the mesophotic but above the deep aphotic, we propose “rariphotic.” Together with the “altiphotic,” proposed here for the shallowest reef-faunal zone, and the mesophotic, the rariphotic is part of a depth continuum of discrete faunal zones of tropical reef fshes, and perhaps of reef ecosystems in general, all of which warrant further study in light of global declines of shallow reefs. Studies of deep tropical-reef ecosystems have surged during the past decade1–10. This is due in part to the global decline of shallow coral reefs having sparked interest in the potential for deep reefs to act as refugia for shallow-water organisms stressed by warming surface waters or deteriorating reefs.

  • Effects of Sea Level on Reef Habitats of Papahānaumokuākea Marine National Monument During the Last Glacial Maximum
    Effects of Sea Level on Reef Habitats of Papahānaumokuākea Marine National Monument during the Last Glacial Maximum A THESIS SUBMITTED TO THE GLOBAL ENVIRONMENTAL SCIENCE UNDERGRADUATE DIVISION IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF BACHELOR OF SCIENCE IN GLOBAL ENVIRONMENTAL SCIENCE DECEMBER 2011 By Keolohilani H. Lopes Jr. Thesis Advisor Charles H. Fletcher, III We certify that we have read this thesis and that, in my opinion, it is satisfactory in scope and quality as a thesis for the degree of Bachelor of Science in Global Environmental Science. THESIS ADVISOR Charles H. Fletcher, III Department of Geology ii DEDICATION I dedicate this paper to my family for their support over the years and the sacrifices they made to allow me to return to school. I would also like to dedicate this, and future works to my nephew Luke and his generation. This scientific research is aimed to maintain a healthy environment so he, and future generations will be able to enjoy the natural beauty and resources as our ancestors have. Mahalo Nui. iii Acknowledgments A special thanks goes out the Cori Kane whom brought me on as a safety diver for my first research cruise to Papahānaumokuākea Marine National Monument (PMNM), it was a very special cruise for me being a native Hawaiian and as a scientist. I would also like to thank Randy Kosaki, Chief Scientist, and the rest of the scientist at PMNM for making me feel welcome. I’d also like to thank Richard Pyle whom first sparked my curiosity into trying to explain the extraordinarily high rate of endemism in the monument.

Rebreather divers appreciate the formalise risk assessment in a CCR. The advantage of value of training, pre-dive checks and equipment this technique over others, such as Failure Modes and maintenance but it is often difficult to visualise just how Effect Criticality Analysis (FMECA), is that it is possible important these factors are and how they inter-relate to visualise the risk easily and see how common human for a rebreather. In this paper, the well-known tech- factors, such as training, pre-dive checks and design, nique of fault tree analysis (FTA) is used to identify risk impact on safety. It is this combination of inter-related in a rebreather. Due to space constraints, only the human issues that makes rebreather diving so interest- branch of the tree for unconsciousness as a result of ing, especially for the risk analyst.
