JW Fishers Mfg., Inc. / 1953 County Street / East Taunton MA 02718 USA (800)822-4744 or (508)822-7330 / Email: info@jwfishers.com / www.jwfishers.com Underwater Search Equipment it PAYS to Own Frozen Fish Lake, Plain WA Air bubble under ice of an underwater metal detector for use on a salvage project. He discov- ered that there was no such device available and built his own: the Mark 1. The detector quickly gained popularity, and customer demands for new and more powerful models developed. As a result, the com- pany expanded the product line from diver-held detectors to boat- towed metal detectors (Mark 7) and magnetometers (Proton 1). In the following decades, the company introduced the DV-1 dropped cam- era system, Pulse 8X hand-held un- derwater metal detector, SeaOtter ROV, SeaLion ROV, side scan sonar system, acoustic pingers, cable and pipe trackers and sub-bottom profil- er. Recently, Fishers introduced the SAR-1 search and recovery wireless metal detector. JW Fishers will cele- brate its milestone 50th year with a tribute on www.jwfishers.com. Assessment of Alternative Fuels for Global Sulphur Cap DNV GL has issued the white paper "Alternative fuels and tech- nologies for greener shipping," examining the price, availability, regulatory challenges and environ- mental benefits of alternative fuels and technologies, including LNG, LPG, hydrogen, fuel cells and hy- brid and battery technologies, and comparing them to the use of con- ventional fuel with scrubbers and new low-sulphur alternatives. The paper offers insights to the shipping industry in preparation for the up- coming Global Sulphur Cap, due to come into effect January 1, 2020. For newbuilds, the sulphur cap could be a major driver for alter- native fuels, and LNG is the prime contender. Earth Challenge 2020 Encourages Citizen Science Earth Day Network, the Wood- row Wilson International Center for Scholars and the U.S. Department of State, through the Eco-Capitals Forum, announced Earth Challenge 2020, a Citizen Science Initiative, a collaboration with Connect4Cli- mate—World Bank Group, Con- servation X Labs, Hult Prize, Na- tional Council for Science and the Environment (NCSE), Open Geo- spatial Consortium (OGC), Reset, SciStarter, UN Environment and others. Millions of global citizens will collect data points for air and water quality, pollution and human health. In 2019, hackathons will be hosted around the world. The initial data collection cam- paign will launch April 1, 2020, with the objective of collecting 1 billion data points by Earth Day. Higher Bandwidth Trend For Vessels Demand for higher bandwidth is rising in the shipping industry, ac- cording to World-Link Communica- tions. The number of ships switch- ing to improved connectivity is also increasing. The per gigabyte cost is dropping, but the monthly spend is roughly the same because of high- er bandwidth usage. Some vessels are now running 40 to 50 GB per month. ST
