oceanbusiness Mississippi River Floods, Locks Closed The U.S. Army Corps of Engineers closed locks on the Mississippi River twice in June, spanning a stretch of the river from Iowa to Missouri, Reuters reported. Heavy rains forced the river to food over, with more rain expected for the area at press time. Among the locks to be closed were Locks 12, 13, 16, 17, 18, 20, 21, 22 and 24. Given the unpredictable weather, the Corps could not give an estimate of when the locks would be reopened. The loading of grain barges was interrupted by fooding because the rising waters prevented the vessels from positioning themselves beneath the loading spout above the river. Senesco Marine Delivers Commercial Floating Dock Senesco Marine (North Kingstown, Rhode Island) launched a commercial foating dry dock in the northeast United States. Senesco built the dry dock for Caddell Dry Dock and Repair Co. Inc. (Staten Island, New York). The dry dock is 420 feet long and has a 100-foot-wide, open pontoon deck. It was designed to accommodate large tank barges, tugs, workboats and U.S. Coast Guard cutters. The dock has 8 pairs of compartments with a safety deck 12 feet above the pontoon deck. The design incorporates large side openings through the wing walls to allow machinery and personnel access to the pontoon deck. Ocean Observatories Initiative to Receive Echosounders From Kongsberg Echosounders from Kongsberg (Kongsberg, Norway) will play a part in the American Ocean Observatories Initiative (OOI) for the monitoring of subsea life along both U.S. coasts. OOI is a cable-based array of scientifc sensors designed to monitor the marine habitat. Everything from fsh and plant life to chemical, physical and geological changes will be measured. Similar initiatives are taking off on the coasts of Australia, Canada and Africa, as well as in Norway's Arctic waters of Lofoten. Geomarine Completes North American geoROV Survey Geomarine Ltd. (Newcastle upon Tyne, England) completed a geoROV CPT survey in North America. The geotechnical survey in the Gulf of Mexico was in support of a pipeline construction project, and work comprised of in-situ testing, interpretation and production of the fnal reports. The geoROV is an ROV-conveyed geotechnical testing and sampling system. Greensea Delivers Navigation Systems Greensea Systems Inc. (Richmond, Vermont) ended a research and development effort with the delivery of four navigation and control systems. The deliveries consisted of navigation and control software suites for a standalone 50 st / July 2013 inertial navigation system (INS), a 1,000-meter-rated commercial AUV, a 6,000-meter work-class ROV and a retroft for a miniature ROV. The effort focused on modularizing Greensea's software architecture to allow for more fexibility and portability across hardware platforms. The ROV systems provide autonomous operating modes, route following, station keeping, dynamic positioning and vehicle control on top of an integrated INS core. Decline in Panama Economic Growth Panama's economy sank to its lowest point in two years in March, reported Reuters. According to the nation's government, there was less activity at the canal and ports as delays in expansion have postponed the opening. The loss of business from two prominent companies could result in $40 million less in revenue for the coming year. The companies are redirecting shipping routes to pass through the Suez Canal, which allows for larger ships carrying greater loads. In 2012, the country saw more than 10 percent economic growth. But the number dropped to 8 percent in three months. The canal is expected to open in mid-2015. Tidal Data Available in Herradura, Costa Rica The Los Suenos Marina (Herradura, Costa Rica) now has daily tidal data available for its users and the nearby community. Original specifcations for the system were for routine monitoring, with a future upgrade to a tsunami warning station planned. Data transmission is via NOAA's GOES Satellite Service. Data will also be received and managed by the University of Hawaii Sea Level Center (UHSLC), based in Honolulu, Hawaii. The UHSLC collaborates with agencies within host countries for the installation and maintenance of a global network of tide gauge stations, which meet standards that range in resolution from tsunami warning to global sea level rise. Home-Grown Buoy System for Brazil RDSEA International (St. Pete Beach, Florida) assisted AMBIDADOS (Rio de Janeiro, Brazil) and the Oceanographic Institute, University of Sao Paulo (Sao Paulo, Brazil) with the deployment of Brazil's frst home-grown buoy system, ATLAS-B, in the Atlantic. Averaged data are transmitted daily for post-processing and dissemination. The system has a 100 percent data stream, with data fowing from the western Atlantic. Full meteorology is also incorporated into the buoy's data set. These data will support ocean and climate research being conducted in the southeastern Brazilian Bight region. Court Allows Savannah Construction to Begin U.S. District Judge Richard M. Gergel accepted the settlement agreement between all parties involved in the mediation over the Savannah Harbor Expansion Project (SHEP) in an order that dismissed the federal litigation pending against the proposed deepening of the harbor channel. Georgia Governor Nathan Deal recently signed a 2014 state budget that includes $50 million in state bonds for SHEP construction, bringing the total state dollars allotted to the project to $231.1 million. The harbor deepening is necessary to better accommodate the larger container ships that already arrive through the Suez Canal and soon will www.sea-technology.com
