  • This Keyword List Contains Indian Ocean Place Names of Coral Reefs, Islands, Bays and Other Geographic Features in a Hierarchical Structure
    CoRIS Place Keyword Thesaurus by Ocean - 8/9/2016 Indian Ocean This keyword list contains Indian Ocean place names of coral reefs, islands, bays and other geographic features in a hierarchical structure. For example, the first name on the list - Bird Islet - is part of the Addu Atoll, which is in the Indian Ocean. The leading label - OCEAN BASIN - indicates this list is organized according to ocean, sea, and geographic names rather than country place names. The list is sorted alphabetically. The same names are available from “Place Keywords by Country/Territory - Indian Ocean” but sorted by country and territory name. Each place name is followed by a unique identifier enclosed in parentheses. The identifier is made up of the latitude and longitude in whole degrees of the place location, followed by a four digit number. The number is used to uniquely identify multiple places that are located at the same latitude and longitude. For example, the first place name “Bird Islet” has a unique identifier of “00S073E0013”. From that we see that Bird Islet is located at 00 degrees south (S) and 073 degrees east (E). It is place number 0013 at that latitude and longitude. (Note: some long lines wrapped, placing the unique identifier on the following line.) This is a reformatted version of a list that was obtained from ReefBase.

Yet he must protect himself against their dangers. Dräger’s ‘Technology For Life’ has been helping people deal with the elements for 125 years. “To ward off these four elements, most especially when they rage wild and tumultuous, without allowing the threatened human life to be torn away by their power and energy, and to rein those elements back in again – that has always been, from the very earliest beginnings, the mission of Dräger.” Senior Pastor Wilhelm Mildenstein, St. Mary’s Church Lübeck, on January 16, 1928, at the funeral of Bernhard Dräger People have fought over clean water just as they have fought over access to the seas. From early times they have considered lakes, seas, and rivers as transport routes and means of conquest. Enormous pressure, cold, darkness and of course the absence of breathable air make the depths of the ocean a place still largely unknown – the first deep sea dive was in 1960 when the Swiss Jacques Piccard and his companion, the American Naval Lieutenant Don Walsh, dived to almost 11,000 meters in their submersible, the Trieste. Despite protective equip- ment, the underwater world remains one of the loneliest and most challenging places to work.

World War II was extraordinarily War complex II and dynamic. The Atlantic and Pacific Theaters were radically different from one another, and as the war progressed, the way the war was fought and the tools used to fight the war continuously evolved. Early on, Winston Churchill secured from President Roosevelt an agreement that the Allies would put their main effort into defeating Germany first, and then they would together turn their attention to the Pacific. This “Europe First” policy was not an easy one for Roosevelt to sell to the military, considering it was the Japanese attack on Pearl Harbor which had forced America into the war. It was especially difficult for the United States Navy to deal with this policy. The US Navy considered the Pacific to be their war and, after the attack on Pearl Harbor, this is easy to understand.

Dominant species caught were Decapterus spp. having 70.09% of the total catch, followed by Selar spp. at 12.66% and Rastrelliger spp. 10.70%. Among the Decapterus spp. caught, D. macrosoma attained the highest total catch composition by species having 68.81% followed by D. kurroides and D.russelli with 0.31% and 1.14% respectively. The round scad fishery stock was composed mainly of juvenile fish (less than 13 cm) and Age group II (13 cm to 14 cm). Few large round scad at Age group IV and V (20 cm to 28 cm) stayed at the fishery.

  • Shark Aggregation and Tourism: Opportunities and Challenges of an Emerging Phenomenon
    Shark aggregation and tourism: Opportunities and challenges of an emerging phenomenon NIR NECKER ZIV ZEMAH SHAMIR , SHIRI ZEMAH SHAMIR NIR BECKER, DEPARTMENT OF ECONOMICS AND MANAGEMENT, TEL-HAI ACADEMIC COLLEGE, ISRAEL. E-MAIL: [email protected] ZIV ZEMAH SHAMIR, Marine Biology Department, M. Kahn Marine Research Station, University of Haifa, Haifa, Israel. E-mail: [email protected] SHIRI ZEMAH SHAMIR, School of Sustainability, Interdisciplinary Center Herzliya, P.O. Box 167, Herzliya 46150, Israel. E-mail: [email protected] Abstract In the last few winters, sharks have been aggregating near the Israeli Mediterranean coast, at a specific point, near Hadera power station. This unusual phenomenon has fascinated residents, visitors, kayakers, divers and swimmers. We analyse the effects of this intense human interest on the sharks, using contingent behaviour, in Hadera and in Ashkelon, where sharks are present but not the infrastructure for their observation. We also report on changes in shark behaviour due to change in tourism intensity. We find a change of about ILS 4.1 million annually for both sites but a larger individual consumer surplus in Hadera, where sharks are currently observable. Touristic intensity crosses the threshold level by about 12% and making the socio-equilibrium sustainable for both humans and sharks would have a social cost of ILS 0.157 million. Keywords: Shark aggregation, shark behaviour, human-wildlife conflict, Mediterranean, Travel cost, tourism. 1 1. Introduction Sharks (superorder Selachimorpha) are characterized by K-selected life history traits, including slow growth, late age-at-maturity and low fecundity. Thus, once a population is depleted, recovery to pre-exploitation levels may take several decades or longer (Kabasakal et al.

Rizalthus, new genus, with just one species, R. anconis, new species, can be distinguished from allied genera by characters of the carapace, epistome, chelipeds, male abdomen and male fi rst gonopod. Visayax, new genus, contains two new species, V. osteodictyon and V. estampadori, and can be distinguished from similar genera using a combination of features of the carapace, epistome, thoracic sternum, male abdomen, pereiopods and male fi rst gonopod. A new species of Hepatoporus Serène, H. pumex, is also described. It is distinguished from congeners by the unique morphology of its front, carapace sculpturing, form of the subhepatic cavity and structure of the male fi rst gonopod.

The area teems of history that spans the centuries with more than 150 wrecks that are scattered across the seabed from 18th century sailing ships to more recent fishing vessels. We plan to dive on the wrecks of the German fleet including the SMS Coln, Brummer, Dresden, Markgraf, Konig, and others. The massive hulking wrecks are truly amazing with so much to explore. The un-salvaged vessels of the German High Sea Fleet offer some of the greatest wreck diving the world has to offer. Truly a bucket list trip for any wreck diver! We will be staying aboard the Valhalla, a newly refurbished live-aboard diving vessel. This is one adventure you will not want to miss!
