There are numerous human and environmental challenges to coral reefs that leave many species of scleractinian corals globally threatened. The EDGE of Existence (Evolutionarily Distinct and Globally Endangered) programme commenced in 2007 at the Zoological Society of London (ZSL). The purpose of the programme was to focus resources for science and conservation on species where little research had been done, or where there were no conservation plans. The programme was developed to support EDGE Fellows who came from, and were based, in the countries where the EDGE species existed. So far, 58 Fellows have been supported, in 33 countries. The Fellowship lasts 2 years, and provides training to develop science and conservation techniques, including outreach and policy development. A grant enables initial implementation of the project. The EDGE programme aims to train future leaders in conservation science. In 2011 the programme was expanded from mammal, amphibian, reptile and bird species to include coral reefs. Specific training in coral reef biology, taxonomy and ecology is provided, together with SCUBA training if necessary. Marine conservationists are able to target conservation projects directed to specific species in Africa, Asia and the Americas.

This short article deals with useful and modern bubble models used to stage divers to the surface and correlations, if and when they exist, with actual data, usually decompression sickness (DCS) outcomes across a limited spectrum of exposures. Many of the early (wet) tests were carried out by world Navies, later by hyperbaric chamber testing and today also by statistical inference from downloaded computer profiles. All have contributed to correlation of models and data but in varying degrees as the scope of mixed gas, open circuit (OC) and rebreather (RB), nonstop to saturation and sea level to altitude diving is immense. No amount of wet or chamber testing will ever cover the ground here, but there is considerable hope and potential for downloaded computer profile data coupled to DCS outcomes to provide necessary correlations across the varied activities of modern diving.

This paper is focused on the Ecosystem Approach Framework for Planning and Management of Coastal Wetlands “EA-PMCW”, as one of the novel Ecosystem Approach’s customized frameworks. The EA-PMCW was developed by Ghoneim SA to support the land use planning and development decision in coastal wetlands as an example of the most sensitive and productive ecosystems on earth. However it translated the principles of the ecosystem approach into a step by step methodology considering the requirements of the planning process, it reflected the especial features of coastal wetlands and the challenges they are facing, including development pressures and increased impacts of climate change. The paper aims to test the applicability of the EA-PMCW within the context of the Egypt, as a rich representative case study. It starts with a brief description of the EA-PMCW and its main feature. Then it tests the applicability through exploring the potentials and challenges involved in applying different stages of the EA-PMW in Egypt. The results show high level of acceptability from the decision-makers and a promising level of applicability. Finally, some recommendations towards successful application could be extracted based on tackling the challenges and maximizes the potentials within the local context.

In this paper, I have reviewed some basic concepts of the plate tectonics theory in a plain geological language with the aim of encouraging geologists to correctly understand this theory in its applications to geological problems. I emphasized the decisive role of subduction as the ultimate (dominant) driving force of all the plate tectonics phenomena. Hence, my discussion has focused on major issues such as the origin of subduction zones, slab rollback, trench retreat, trench suction and driving mechanism of plate motion (both oceanic and continental) by means of illustration with hypothetical and real examples. As much of the discussion is heavily based on my personal (original) perspectives, some of the concepts, interpretations and hypotheses may not be familiar to many and may not be readily found in the existing literature. Mantle plume hypothesis is not the focus of this paper and is thus only mentioned in passing.

Sequences developed within the middle Miocene in the study area are interpreted to be controlled locally by episodic shelf instabilility, basin physiography (shelf edge), fault growth and linkage. Relative sea level changes provide the major control on sequence development and deep valley incisions. The latter have a strong geomorphological impact on the area and a strong control on sequence variability. Interpretation of GDE maps shows that sands were originally deposited in river- and mouth bars with longshore drift currents redistributing the sand parallel to the shoreline. During lowstand periods, canyons developed which served as conduits for sand to the basin (deep water sand), recognized as high amplitude seismic facies on the slope and on the basin floor. This mechanism has led to the deposition of considerable amount of sandstones in the slope and offshore environments. Idealized schematic sequence stratigraphic development models have been generated for the study area, while schematic palaeogeography and general conceptual depositional models of the study area during middle Miocene time are also presented.

Our overall goal is to analyze dolphin sounds to determine if dolphins utilize language or perhaps pictorial information in their complex whistles and clicks. We have recently discovered a novel phenomenon in images derived from digital recordings of the sounds of dolphins echolocating on submerged objects. Hydrophone recordings of dolphin echolocation sounds were input to a CymaScope, an analog instrument in which a water-filled, fusedquartz cell is acoustically excited in the vertical axis by a voice coil motor directly coupled to the cell. The resulting wave patterns were recorded with a digital video camera. We observed the formation of transient wave patterns in some of the digital video frames that clearly matched the shapes of the objects on which the dolphin echolocated, including a closed cell foam cube, a PVC cross, a plastic flowerpot, and a human subject. As further confirmation of this phenomenon the images were then converted into 3-dimensional computer models. The computer models were made such that the thickness at any given point was proportional to the brightness of a contrast-enhanced image with brighter areas thicker and darker areas thinner. These 3-dimensional virtual models were then printed in photopolymers utilizing a high definition 3D printer.

Welch method have result in marker 1 (perpendicular line) with clay color have (x) 1365 and (y) -32,67 dB, and marker 2 with interrupted line have (x) value 2728 and (y) value -32.46 dB Welch power spectral density is a good method used for signal and spectrum analysis with object signature whistle of bottlenose dolphins.","PeriodicalId":331621,"journal":{"name":"Journal of Marine Science: Research & Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131376855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
