AbstractThe Gulf of Mexico Coastal Hypoxia Glider Experiment was designed to assess the feasibility of using ocean glider technology in the coastal hypoxic zone of the northern Gulf of Mexico in Summer/Fall 2014. The objectives were (1) to coordinate and operate multiple autonomous buoyancy ocean gliders in depths less than 50 m and (2) to determine how close to the bottom gliders can reliably reach without making contact. Strong vertical and horizontal stratification gradients, strong coastal currents, and the low-oxygen conditions that occur within the lower water column characterize the coastal area of the northern Gulf of Mexico. These environmental conditions combine with the presence of more than 5,000 surface piercing oil/gas structures to make piloting and navigation in the region challenging. We quantify glider performance to assess the usefulness of buoyancy gliders to address the National Oceanic and Atmospheric Administration Action Plan goal to monitor the spatial extent, duration, and severity of the Gulf hypoxic zone. We find that the gliders, despite the operational challenges, were consistently able to travel from the surface to the oxygen-depleted depths of subpycnocline waters, that is, within 2 m of the ocean bottom. Our assessment is that gliders are able to provide real-time observations suitable to monitor coastal hypoxia.

Strategic, data driven conservation approaches are increasing in popularity as conservation communities gain access to better science, more computing power, and more data. High resolution geospatial data, indicating ecosystem functions and economic activity, can be very useful for any conservation expert or funding agency. A framework was developed for a data driven conservation prioritization tool and a data visualization tool. The developed tools were then implemented and tested for the U.S. Gulf of Mexico coastal region defined by the Gulf Coast Ecosystem Restoration Council. As a part of this tool development, priority attributes and data measures were developed for the region through 13 stakeholder charrettes with local, state, federal, and other non-profit organizations involved in land conservation. This paper presents the measures that were developed to reflect stakeholder priorities. These measures were derived from openly available geospatial and non-geospatial data sources. This database contained 19 measures, aggregated into a one km2 hexagonal grid and grouped by the overarching goals of habitat, water quality and quantity, living coastal and marine resources, community resilience, and economy. The developed measures provided useful data for a conservation planning framework in the U.S. Gulf of Mexico coastal region.

An unprecedented land conservation effort is presently underway in the Gulf of Mexico Coastal Region (GCR) due to an influx of funds from settlements related to the 2012 RESTORE Act. A complete understanding of the priorities of the states in the GCR is critical to ensure that land conservation planning efforts are implemented effectively and efficiently. The paper reviews past, current, and future land conservation priorities in the GCR to inform strategic planning efforts. This review catalogs an extensive list of projects and plans proposed and implemented at federal, state, county, and city levels with direct ties to land conservation during the past 20 years. Comprehensive restoration goals proposed by the Gulf Coast Ecosystem Restoration (Restore) Council were used as a framework for grouping priorities within conservation plans and projects. Plans were first compiled via internet searches and expert sources, then a series of eight stakeholder charrettes were held across the GCR states to validate the catalog and add missing projects and plans. A geospatial web tool was developed using the Restore Council goal framework to allow for the identification and exploration of plans in the GCR.

The foundation problems of the coastal region of the Gulf of Mexico are unique. Normally, a coastal region is thought of as the land area, such as a plain, adjacent to a body of water. Such a region usually is somewhat regular in its geology and because of the natural resources, terrain or climate may be given to a relatively common industry involving a somewhat similar development throughout. The coastal region of the Gulf of Mexico, as regards the United States, violates this criterion in a multitude of ways. The region is not limited to the coastal plain bordering the Gulf of Mexico, by any means, but, rather has been broadened by our commerce and the need for the development of natural resources to also embrace, the delta areas and offshore belt extending to the limit of the continental shelf, lying as far as 70 miles from the shore. The delta areas have long been avoided in the past by industry of all types that is, with the exception of the fishing industry, because of the unstable nature of the foundation media. Likewise the continental shelf area normally is not considered for industrial development because of the availability of the more desirable coastal plain. However, the quest for natural resources, like sulphur and petroleum, in spite of the efforts toward Federal Control, has made necessary the solution of very extraordinary foundation problems in this offshore area. In addition to the foregoing unusual aspects of the foundation problems of the Gulf Coast, the coastal plain is unusual in itself because this region at one time formed the floor of the Gulf of Mexico and, as the sea receded or the land was uplifted, the residual sedimentary soils have been drained and desiccated to result in unusual formations that serve as foundation media for the industrial and domestic developments of the region. The foregoing factors combine to make the foundation problems of the Gulf of Mexico Coastal Region very interesting.

Lime Production

Mexico produces the three most important types of lime: Mexican, Persian, andItalian. Persian lime (Citrus latifolia) is the second most important in planted area.Forty-six percent of the production is intended for export. The objective of thisresearch was to analyze the Persian lime value network of the packing andexporting companies. It was conducted at the main Persian lime producing area,located in the central coastal region of the Gulf of Mexico. As an average, thesampled companies were using 55% of their packing capacity. Most of them (83%)work all year long. They have been from 6 to 15 years in operation. Theyemployed a mean of 41 people, thus they are medium-size enterprises. Fourteenactors were complementing their business in production and marketing. Therelationship between packers and the small lime producing farmers was veryinequitable. Low prices were common for Persian lime producers.The fruits theywere packing came mainly from local producers (90%).Their main exportdestinations were: United States, Europe, Canada, and Japan. Other regions areincreasing Persian lime production, threatening the marketing of the farmers of thecentral coast of the Gulf of Mexico.
