Changing the conditions of offshore environment influences the offshore units' stability. In paper, a study of the impact of marine environment on a jackup rig was implemented. Firstly, the procedures of departure, transit, and emplacement on any emergency jacking location / stand by location are reviewed. After that, the conditions of weather forecasting are predicted and computed such as wave and wind lengths, speeds, and heights. Maps of changing wind and wave conditions are plotted. Surveying methods are used to determine the final location of the jackup rig. Maps of positioning the jackup

The attractiveness and durability of stone claddings make them a common exterior finish. However, comparative research of the performance of long-lasting “dry fixed” stone claddings and those made using the “wet fixed” method has not yet been carried out. The objectives of this study are to (1) characterize the deterioration patterns of exterior dry- and wet-fixed stone claddings exposed to normal and marine environments; (2) evaluate the life expectancy limiting coefficient (modifying factors), and (3) quantify the influence of a marine environment on both cladding methods.

Large-scale atmospheric conditions in the Northeast Pacific Ocean affect both the freshwater environment in the Columbia River Basin and marine conditions along the coasts of Oregon, Washington, and British Columbia, resulting in correlated conditions in the two environments. For migrating species, such as salmonids that move through multiple habitats, these correlations can amplify the impact of good or poor physical conditions on growth and survival, as movements among habitats may not alleviate effects of anomalous conditions. Unfortunately, identifying the mechanistic drivers of salmon sur

Sea environments harbor a wide variety of life forms that have adapted to live in hard and sometimes extreme conditions. Among the marine living organisms, extremophiles represent a group of microorganisms that attract increasing interest in relation to their ability to produce an array of molecules that enable them to thrive in almost every marine environment. Extremophiles can be found in virtually every extreme environment on Earth, since they can tolerate very harsh environmental conditions in terms of temperature, pH, pressure, radiation, etc. Marine extremophiles are the focus of growing

The marine and coastal ecosystems are economically and culturally important, especially for the people depending on them. However, these resources are vulnerable to over-harvesting, pollution, coastal development, and destructive fishing. The condition of small-scale fisheries in the Philippines has deteriorated due to these anthropogenic activities. Given this situation, greater efforts are required for the country to develop sustainable strategies to rehabilitate the coastal environment and mitigate the declining marine resources.

An ecologically based conceptual foundation is presented as a way to incorporate environmental variability in salmon management. The argument addresses the problem of accommodating marine environment variability through actions in freshwater. We argue for an approach that considers marine and freshwater environments as integral components of a larger salmonid ecosystem. This contrasts with previous propositions that either relied heavily on technological fixes in the freshwater environment or questioned the value of any recovery effort designed to withstand overwhelming ocean forces.

This paper examines the economic effects of management policies on four of the seven beach-seine net fishing operations in False Bay. The effects of past regulations are examined by assessing whether or not this industry is at present profitable. It was found that under the present management policies all fishing crews are profitable. A new policy preventing fishermen from catching white steenbras has been introduced. This was examined and it was shown that only one of the crews examined would be effected. Two proposed policies were examined to determine their impact on the sector. The first p

Like all intertidal species, the barnacle Balanus glandula must cope with temperature and desiccation stress during daily low tide exposure. The increase in temperature at low tide leads to both increased metabolic rate and the potential for increased ATP demand. With its additional inhibition of oxygen intake, low tide thus has an energetic cost that is often reflected in an increase in oxygen consumption following resubmersion. As anthropogenically induced global climate change increases air and water temperatures, its cost might increase. B. glandula individuals were exposed to 4‑hour low t

Abstract The following paper describes a model designed to estimate corrosion-related metal loss and loss patterns on structures exposed in a marine environment. In particular, the model addresses corrosion of coated carbon steel structures subject to immersion conditions. Critically, it offers an alternative to the common practice of assuming uniform metal loss and static coating breakdown characteristics. The distinction between uniform metal loss and actual loss patterns can have significant impacts regarding the lifetime integrity of an engineered structure in a marine environment.

Abstract Microbiologically Influenced Corrosion (MIC) occurs in environments where microbial attachment and biofilm formation occurs. The microbial metabolic activities which cause MIC affect materials in a wide variety of industries. Although MIC has not traditionally been a major durability concern for Florida coastal and inland bridges, a recent finding by the Florida Department of Transportation (FDOT) of severe corrosion of steel bridge piles with strong evidence of microbial activity, has motivated the present study. As a preliminary research, identify the possible susceptibility of a ca

Abstract Coating systems for corrosion mitigation of structural steel and reinforcing steel in marine bridge applications have been widely used. However, novel materials continue to become available and interest lies in identifying improved material performance for marine bridge applications. Research in progress considered Thermal Diffusion Galvanizing (TDG) with various industry-recommended topcoats. Test parameters included evaluating local coating defects such as abrasion, environmental conditions, and chloride contamination. Physical parameters such as coating thickness and adhesion were

The aim of this contribution is to analyse the award rendered in 2024 by an ICSID Tribunal in the investor-State dispute of Odyssey Marine v. Mexico. The case concerns the refusal by Mexico of an environmental permit for Odyssey’s seabed mining project due to environmental concerns, which prompted the company to claim that Mexico had violated several provisions of the North American Free Trade Agreement. This contribution argues that two main takeaways may be inferred from the Award. First, it underscores the tension between the legal protection of foreign investments and the necessity to prot

A digital compilation of updated postglacial marine limits was completed in the coastal regions of central mainland Nunavut and northern Manitoba between Churchill and Queen Maud Gulf. The compilation builds on and updates previous mapping of the marine limits at an unprecedented scale, making use of high-resolution digital elevation models, new field-based observations of the marine limit and digital compilations of supporting datasets (i.e. marine deltas and marine sediments). The updated mapping also permits a first-hand, knowledgedriven interpolation of a continuous limit of marine inundat

Northern Yukon hosts occurrences of Middle Devonian hyper-enriched black shale (HEBS) Ni-Mo-Zn-platinum-group element-Au-Re mineralization, including the Monster River showing in the Ogilvie Mountains. This mineralization has been documented predominantly in the Paleozoic Richardson trough; however, the Monster River showing is atypical, occurring within the Blackstone trough, more than 200 km to the west on the southern margin of the Yukon block. The ambient paleoredox conditions of the marine water column and sediments may be primary controlling factors in HEBS formation. We use major and tr

While originally developed for weather forecasting, the Extreme Forecast index (EFI) concept has found utility in diverse fields. This study marks the inaugural application of EFI principles to numerical ocean forecasting. EFI offers a metric to gauge the forecast's deviation from historical norms specific to the location and time of year. A heightened EFI value signifies that the forecast falls beyond the usual range of variability, signifying a higher probability of extreme conditions. This novel use of EFI stands to benefit oceanographers by identifying significant oceanic events, aiding de

Ammonia waste removal in recirculating aquaculture systems is typically accomplished via the action of nitrifying bacteria in specially designed biofilters that oxidize ammonia to produce nitrate. In the majority of these systems nitrate is discharged to the environment through frequent water exchanges. As environmental considerations have made it necessary to eliminate nitrate release, new strategies for nitrate consumption are being developed. In the funding period we showed that ammonia removal from wastewater could take place by an anaerobic ammonia oxidation process carried out by bacteri

Description: Shipping is responsible for a range of different pressures affecting air quality, climate, and the marine environment. Most social and economic analyses of shipping have focused on air pollution assessment and how shipping may impact climate change and human health. This risks that policies may be biased towards air pollution and climate change, whilst impacts on the marine environment are not as well known. One example is the sulfur regulation introduced in January 2020, which requires shipowners to use a compliant fuel with a sulfur content of 0.5% (0.1% in SECA regions) or use

Wind Cave National Park (WICA), the first cave in the world to become a national park, is famous for the park’s namesake feature. Wind Cave, named for the noticeable wind-flow patterns observed as air moves in and out of the natural cave entrance, is currently the third longest cave system in the United States and seventh longest in the world. Wind Cave formed when groundwater dissolved buried layers of the fossiliferous Madison Limestone, which were deposited during the Mississippian subperiod approximately 359 to 347 million years ago. In addition to the Madison Limestone, several other form
