The arrest of ships in maritime zones beyond internal waters in Belgian maritime law

Opportunities may arise to arrest a ship in maritime zones beyond internal waters, e.g. in the territorial sea and the exclusive economic zone (EEZ). This paper examines the possibilities for arrest in those areas on the basis of jurisdiction ratione loci and ratione materiae. Under Belgian law the territorial sea is not part of the State's territory; accordingly, the Belgian Judicial Code does not provide for an attachment judge nor a bailiff to have jurisdiction in this area and a fortiori in the EEZ. The law of April 22, 1999 solved the problem of territorial jurisdiction in this respect. As far as a ship's arrest in the EEZ is concerned, it is not clear whether the United Nations Law of the Sea Convention (articles 73 and 220) combined with the requirement of a maritime claim, allows for an arrest at all.

The strength of Malaysian maritime cluster: The development of maritime policy

A comprehensive maritime industry policy that can be adequately monitored to achieve a competitive advantage is important. The Malaysian maritime industry comprises multifaceted sectors that are governed by fragmented governmental agencies. In this research, we investigated the Malaysian maritime industry cluster comprising three main sectors: Shipping, Ship Industry, Ports and Terminals. The Strength Indicator Model has been developed to reveals the maritime industry cluster. We find that the Competitions, Locations, Connections, Government and Chances factors affect the capability of the Malaysian maritime industry cluster. The result of this study will give a framework for Regulatory bodies and the various stakeholders to support the Malaysia maritime industry progressing toward a more competitive and sustainable development of the industry with the aim to become the developed maritime nation.     

The maritime radio spectrum future

Future satisfaction of the electromagnetic spectrum needs of the maritime mobile service is dependent on the translation of those needs to frequency allocations. In September 1979, over 100 countries will consider all of the spectrum, and make changes to meet perceived needs of radio services, including maritime needs up to the year 2000. This conference, the World Administrative Radio Conference 1979, will have a significant impact on future maritime radio operations. Issues, procedures, competing requirements, are explored to enable a better understanding of the regulatory process for frequency allocations.

The new system adopts a lot of technical features such as automatic location registration, new signaling methods, etc. An outline of system performance and function is described herein.     

The Portuguese maritime spatial plan

Numerous national governments and supranational organizations such as the OSPAR Commission, the European Union and the United Nations Educational, Scientific and Cultural Organization (UNESCO) have underlined the importance of maritime spatial planning (MSP) for balancing and solving conflicts between the needs of different sectors and conservation in the marine space. In the last decade, many maritime spatial plans have been developed around the world. The drivers to develop these plans and the approaches to find solutions for the particular problems differ significantly. The Portuguese national marine jurisdiction is one of the largest in Europe. For the continental part, a maritime spatial plan was initiated in 2009, and entered in 2010 in the final stage of approval. One of the driving forces for this MSP initiative was the claim to extend its continental shelf. The development process was led by a multidisciplinary team. Despite the challenges, the existing as well as potential future marine resources and activities were characterized, mapped and categorized. To overcome conflicts resulting from the many overlapping uses and to assure sustainable development of all sectors, a conflict analysis and evaluation of potential future uses were necessary. The applied zoning scheme represented an exercise of conflict solving and proved to be a powerful tool to promote discussion and participation among stakeholders. The successful implementation of Portuguese MSP will rely largely on its ability to provide efficient management, financial and legal mechanisms to achieve the integration of all strategies and spaces under the Portuguese maritime jurisdiction.     

The geopolitical dimension of maritime security

This article discusses the geopolitical dimension of maritime security, which has been neglected by scholars despite the growing number of studies devoted to a variety of aspects related to maritime security. The first step consists in clarifying the definitions of the two concepts; ‘geopolitics’ and ‘maritime security’. Then the article introduces the geopolitical dimension of maritime security from a conceptual perspective, and then analyses three practical examples of maritime security geo-strategies released in 2014. The results demonstrate that states’ and international institutions’ maritime security objectives and interests are indirectly and directly influenced by geographical and geopolitical considerations, although this link is only tacitly acknowledged in official documents. Scholars and practitioners interested in maritime security are encouraged to further engage with this dimension.     

Monsoon-driven biogeochemical processes in the Arabian Sea

Although it is nominally a tropical locale, the semiannual wind reversals associated with the Monsoon system of the Arabian Sea result annually in two distinct periods of elevated biological activity. While in both cases monsoonal forcing drives surface layer nutrient enrichment that supports increased rates of primary productivity, fundamentally different entrainment mechanisms are operating in summer (Southwest) and winter (Northeast) Monsoons. Moreover, the intervening intermonsoon periods, during which the region relaxes toward oligotrophic conditions more typical of tropical environments, provide a stark contrast to the dynamic biogeochemical activity of the monsoons. The resulting spatial and temporal variability is great and provides a significant challenge for ship-based surveys attempting to characterize the physical and biogeochemical environments of the region. This was especially true for expeditions in the pre-satellite era.Here, we present an overview of the dynamical response to seasonal monsoonal forcing and the characteristics of the physical environment that fundamentally drive regional biogeochemical variability. We then review past observations of the biological distributions that provided our initial insights into the pelagic system of the Arabian Sea. These evolved through the 1980s as additional methodologies, in particular the first synoptic ocean color distributions gathered by the Coastal Zone Color Scanner, became available. Through analyses of these observations and the first large-scale physical–biogeochemical modeling attempts, a pre-JGOFS understanding of the Arabian Sea emerged. During the 1990s, the in situ and remotely sensed observational databases were significantly extended by regional JGOFS activities and the onset of Sea-viewing Wide Field-of-View Sensor ocean color measurements. Analyses of these new data and coupled physical–biogeochemical models have already advanced our understanding and have led to either an amplification or revision of the pre-JGOFS paradigms. Our understanding of this complex and variable ocean region is still evolving. Nonetheless, we have a much better understanding of time–space variability of biogeochemical properties in the Arabian Sea and much deeper insights about the physical and biological factors that drive them, as well as a number of challenging new directions to pursue.     

Biogeochemical ocean-atmosphere transfers in the Arabian Sea

Transfers of some important biogenic atmospheric constituents, carbon dioxide (CO₂), methane (CH₄), molecular nitrogen (N₂), nitrous oxide (N₂O), nitrate , ammonia (NH₃), methylamines (MAs) and dimethylsulphide (DMS), across the air–sea interface are investigated using published data generated mostly during the Arabian Sea Process Study (1992–1997) of the Joint Global Ocean Flux Study (JGOFS). The most important contribution of the region to biogeochemical fluxes is through the production of N₂ and N₂O facilitated by an acute, mid-water deficiency of dissolved oxygen (O₂); emissions of these gases to the atmosphere from the Arabian Sea are globally significant. For the other constituents, especially CO₂, even though the surface concentrations and atmospheric fluxes exhibit extremely large variations both in space and time, arising from the unique physical forcing and associated biogeochemical environment, the overall significance in terms of their global fluxes is not much because of the relatively small area of the Arabian Sea. Distribution and air–sea exchanges of some of these constituents are likely to be greatly influenced by alterations of the subsurface O₂ field forced by human-induced eutrophication and/or modifications to the regional hydrography.

Globalisation and de-regulation in the maritime industry

The development of the Flags of Convenience (FOC) system has had serious repercussions for labour as shipowners, in search of cheaper crews, have recruited ‘crews of convenience’ from developing nations. This paper examines the record of FOCs to analyse the effects of globalisation upon the working lives of seafarers. The method used will be to compare the regimes of FOCs, and this will be done by the analysis of a flag state conformance index (FLASCI) created by the authors, which utilises a large number of measures of a state's capacity to maintain and enforce a regulatory regime for the vessels flying its flag.     

A decision-making system to maritime risk assessment

In this study, we propose a fuzzy approach in order to evaluate the maritime risk assessment applied to safety at sea and more particularly, the pollution prevention on the open sea. The work is based on the decision-making system, named MARISA, presented in Balmat et al. (2009). This system allowed defining a risk factor for each ship according to ship’s characteristics and weather conditions. In this novel paper, the proposed system takes into account the ship speed evolution and the ship position with respect to maritime shipping lanes is developed. To validate the method, we present an example of results with real data.     

Nitrogen dynamics during the Arabian Sea Northeast Monsoon

This investigation focused on the weaker and less well understood of the two Arabian Sea monsoonal wind phases, the NE Monsoon, which persists for 3–4 months in the October to February period. Historically, this period has been characterized as a time of very low nutrient availability and low biological production. As part of the US JGOFS Arabian Sea Process Study, 17 stations were sampled on a cruise in January 1995 (late NE Monsoon) and, 15 stations were sampled on a cruise in November 1995 (early NE Monsoon). Only the southern most stations (10° and 12°N) and one shallow coastal station were as nutrient-depleted as had been expected from the few relevant prior studies in this region. Experiments were conducted to ascertain the relative importance of different nitrogenous nutrients and the sufficiency of local regeneration processes in supplying nitrogenous nutrients utilized in primary production. Except for the southern oligotrophic stations, the euphotic zone concentrations of NO₃⁻ were typically 5–10-fold greater than those of NO₂⁻ and NH₄⁺. There was considerable variation (20–40-fold) in nutrient concentration both within and between the two sections on each cruise. All nitrogenous nutrients were more abundant (2–4-fold) later in the NE Monsoon. Strong vertical gradients in euphotic zone NH₄⁺ concentration, with higher concentrations at depth, were common. This was in contrast to the nearly uniform euphotic zone concentrations for both NO₃⁻ and NO₂⁻. Half-saturation constants for uptake were higher for NO₃⁻ (1.7 μmol kg⁻¹ (s.d.=0.88, n=8)) than for NH₄⁺ (0.47 μmol kg⁻¹ (s.d.=0.33, n=5)). Evidence for the suppressing effect of NH₄⁺ on NO₃⁻ uptake was widespread, although not as severe as has been noted for some other regions. Both the degree of sensitivity of NO₃⁻ uptake to NH₄⁺ concentration and the half-saturation constant for NO₃⁻ uptake were correlated with ambient NO₃⁻ concentration. The combined effect of high affinity for low concentrations of NH₄⁺ and the effect of NH₄⁺ concentration on NO₃⁻ uptake resulted in similarly low f-ratios, 0.15 (s.d.=0.07, n=15) and 0.13 (s.d.=0.08, n=17), for early and late observations in the NE Monsoon, respectively. Stations with high f-ratios had the lowest euphotic zone NH₄⁺ concentrations, and these stations were either very near shore or far from shore in the most oligotrophic waters. At several stations, particularly early in the NE Monsoon, the utilization rates for NO₂⁻ were equal to or greater than 50% the utilization rates for NO₃⁻. When converted with a Redfield C : N value of 6.7, the total N uptake rates measured in this study were commensurate with measurements of C productivity. While nutrient concentrations at some stations approached levels low enough to limit phytoplankton growth, light was shown to be very important in regulating N uptake at all stations in this study. Diel periodicity was observed for uptake of all nitrogenous nutrients at all stations. The amplitude of this periodicity was positively correlated with nutrient concentration. The strongest of these relationships occurred with NO₃⁻. Ammonium concentration strongly influenced the vertical profiles for NO₃⁻ uptake as well as for NH₄⁺ uptake. Both NO₂⁻ and NH₄⁺ were regenerated within the euphotic zone at rates comparable to rates of uptake of these nutrients, and thus maintenance of mixed layer concentrations did not require diffusive or advective fluxes from other sources. Observed turnover times for NH₄⁺ were typically less than one day. Rapid turnover and the strong light regulation of NH₄⁺ uptake allowed the development and maintenance of vertical structure in NH₄⁺ concentration within the euphotic zone. In spite of the strong positive effect of light on NO₂⁻ uptake and its strong negative effect on NO₂⁻ production, the combined effects of much longer turnover times for this nutrient and mixed layer dynamics resulted in nearly uniform NO₂⁻ concentrations within the euphotic zone. Responses of the NE Monsoon planktonic community to light and nutrients, in conjunction with mixed layer dynamics, allowed for efficient recycling of N within the mixed layer. As the NE Monsoon evolved and the mixed layer deepened convectively, NO₂⁻ and NO₃⁻ concentrations increased correspondingly with the entrainment of deeper water. Planktonic N productivity increased 2-fold, but without a significant change the new vs. recycled N proportionality. Consequently, NO₃⁻ turnover time increased from about 1 month to greater than 3 months. This reflected the overriding importance of recycling processes in supplying nitrogenous nutrients for primary production throughout the duration of the NE Monsoon. As a result, NO₃⁻ supplied to the euphotic zone during the NE Monsoon is, for the most part, conserved for utilization during the subsequent intermonsoon period.
