    NAD 83 and NAVD 88 will be replaced in 2022, and there are many related projects to make sure the transition goes smoothly. Read the NOAA NGS Ten-Year Plan to learn more and continue to visit the NGA web-page for more information.

    This information is very important for coastal and inland areas of the Gulf, such as coastal Louisiana and other coastal states.

    The newest positioning and monitoring station for coastal Louisiana has seen the completion of installation- at Cypremort State Park, located in the central coast of Louisiana.

    Through a five state- Gulf Wide- initiative lead by the University of Southern Mississippi (funded by NOAA Grant Funding), a multi year effort is seeing the planning, design and installation of new GPS (GNSS) based CORS Stations across the entire Gulf Coast. Combined with resources such as the Real Time GPS Network (RTN) by the Louisiana State University Center for GeoInformatics, very accurate positioning (in real time) are available for coastal restoration projects, coastal protection projects, infrastructure and community and industrial projects and programs.

    Special Thanks and Appreciation goes to the Louisiana State Parks, Department of Culture, Recreation and Tourism- for their support and collaboration.

    Thanks to the Texas A&M CBI for their work and the efforts and installation of this station with Louisiana State University C4G.

    Planning for a new GPS CORS Station is now underway for South Plaquemines Parish, Louisiana.

    Good example of former flooded wetland areas subsiding through the draining of the area--6 feet of vertical elevation loss, 1924-2009. A good way to show what happens to exposed organic soils when these (former) wetland soils are drained and exposed to the open atmosphere.

    The last time period rate of elevation loss may be due to the fact the soil has been pretty compacted in the decades before and a lot of the organic material has been oxidized and lost. It would be good to see what the composition of the remaining soil.

    This is seen across wide areas of coastal Louisiana and the northern Gulf. This loss of soil organic material, the compaction and other subsidence effects and the rise of sea levels- all making a relative sea level rise rate about 4 times greater than a coastal area like Pensacola.

    The big issue now is to see this occurring at a very rapid rate in Carbon emission/loss of the northern tundra through melting and fires. The release of carbon (CO2) into the atmosphere from this can be very large.

    On March 15th, The Hydrographic Society of America (THSOA) Southeast Chapter participated in the Biloxi High School Career day. Biloxi High School is one of the largest schools with 1,600 students on the Mississippi Gulf Coast. In a small and comfortable environment, THSOA Southeast Chapter was able to expose at least 200 out of the 800 students who visited the career day to the world of Hydrography.

    At the Career day, there were 23 tables and their primary themes were healthcare and the food/entertainment industry. Only two tables were directly related to science and engineering. Those two organizations were THSOA Southeast Chapter and the MS Department of Marine Resources, DMR.

    THSOA Southeast Chapter informed students on Hydrography along with the associated sciences and engineering. The storyline used was that few know Hydrography as a science and little know the engineering associated with survey. Biloxi High School was grateful for our participation and the Southeast Chapter is glad that many students were exposed to our industry.

    Completely unexpected was one student who saw our banners from across the way and ran up stating, “I can’t believe you are here. This is exactly what I want to do for a career!” She stayed the time allotted while we discussed the society, summer program possibilities, scholarships, educational and employment opportunities.

    Also discussed were academic preparation for whatever the interested student was considering. And of course, letting the students know the importance of their “best” ACT score.

    While there are difficulties in participating in efforts such as this. As examples, you are not the most popular table with Mc Donald’s and Army blow you away and 80% of the students have absolutely no interest but there are 20% do.

    Career day efforts such as these are worth it if we can help steer some to a science and engineering field.

    A report published by Marsh, a leading insurance broker and risk adviser, and a wholly-owned subsidiary of Marsh & McLennan Companies, says bathymetric data, which produces 3D images of seabeds, is "inadequate or non-existent" for large tracts of national and international waters.

    In order to support the growth of the global shipping industry, governments around the world need to invest more in creating and sharing accurate hydrographic information, says Marsh.

    Marsh’s report, 'Plumbing the Depths: Hydrographic Concerns for Modern-Day Large Vessels,' highlights how increasingly large commercial vessels with greater length, width, and depth are navigating vast areas of the world’s seas and oceans. These areas are either unsurveyed or have not been re-surveyed since lead-line soundings were used to measure fathoms nearly a century ago.

    According to the International Hydrographic Organization, nearly half (49 per cent) of the UK’s coastal waters up to 200m have been adequately surveyed to modern standards, with Japan at 46 per cent and Australia at 35 per cent. In the Arctic Peninsula, an increasingly popular destination for cruise ships, virtually all coastal waters up to depths of 200m have not yet been surveyed.

    “This is a pivotal decade in the development of the global maritime industry given the enormous proportions of commercial vessels now plying waters around the world,” said, Marcus Baker, Chairman of Marsh’s Global Marine Practice.

    “The new Suez Canal allows nearly double the previous maximum of vessels to transit the Canal each day; and the new Panama Canal, with its new locks and deeper channels, is set to open later this year. More government investment in hydrographic surveys and the sharing of accurate bathymetric data and hydrographic information is imperative, to protect vessels and the crews that serve on them.”

    In January 2016, the International Maritime Organization (IMO) was granted powers to audit the performance of countries in fulfilling their safety of life at sea (SOLAS) obligations, including the collection and compilation of hydrographic data and the publication and dissemination of all nautical information necessary for safe navigation. However, the IMO currently has no authority to compel countries to fulfil these obligations.

    Steve Harris, Senior Vice President, Marsh’s Global Marine Practice, said: “There are many parts of the world where the salvage industry is ill-equipped to handle large incidents, which is a concern for operators, insurers, salvors, and environmentalists alike. Having these larger vessels, with their increasingly valuable and complex cargoes, sailing through inadequately charted waters has enormous environmental and business interruption implications, should an incident occur.”
