In November 2003 the IMO Assembly adopted Guidelines on Places of Refuge for Ships in Need of Assistance following a two-year deliberation period. The Guidelines were adopted in the wake of the highly publicized ERIKA, CASTOR and PRESTIGE incidents and at the same time as the European Union adopted a regional policy on places of refuge. This paper discusses the problem of places of refuge for ships in distress and analyses the IMO Guidelines adopted as a response to the problem. The paper concludes that the Guidelines constitute a practical modus vivendi for a non-resolvable problem. However, many legal questions remain unanswered and it is likely that the IMO will continue to be seized of the legal aspects of the problem into the future.  相似文献

This paper presents Prototype Système 2 Global (PSY2G), the first Mercator global Ocean General Circulation Model (OGCM) to assimilate along-track sea level anomaly (SLA) satellite data. Based on a coarse resolution ocean model, this system was developed mainly for climatic purposes and will provide, for example, initial oceanic states for coupled ocean-atmosphere seasonal predictions. It has been operational since 3 September 2003 and produces an analysis and a two-week forecast for the global ocean every week. The PSY2G system uses an incremental assimilation scheme based on the Cooper and Haines [Cooper, M., Haines, K., 1996. Data assimilation with water property conservation. J. Geophys. Res., 101, 1059-1077.] lifting–lowering of isopycnals. The SLA increment is obtained using an optimal interpolation method then the correction is partitioned into baroclinic and barotropic contributions. The baroclinic ocean state correction consists of temperature, salinity and geostrophic velocity increments and the barotropic correction is a barotropic velocity increment. A reanalysis (1993–2003) was carried out that enabled the PSY2G system to perform its first operational cycle. All available SLA data sets (TOPEX/Poséïdon, ERS2, Geosat-Follow-On, Jason1 and Envisat) were assimilated for the 1993–2003 period. The major objective of this study is to assess the reanalysis from both an assimilation and a thermodynamic point of view in order to evaluate its realism, especially in the tropical band which is a key region for climatic studies. Although the system is also able to deliver forecasts, we have mainly focused on analysis. These results are useful because they give an a priori estimation of the qualities and capabilities of the operational ocean analysis system that has been implemented. In particular, the reanalysis identifies some regional biases in sea level variability such as near the Antarctic Circumpolar Current, in the eastern Equatorial Pacific and in the Norwegian Sea (generally less than 1 cm) with a small seasonal cycle. This is attributed to changes in mean circulation and vertical stratification caused by the assimilation methodology. But the model's low resolution, inaccurate physical parameterisations (especially for ocean–ice interactions) and surface atmospheric forcing also contribute to the occurrence of the SLA biases. A detailed analysis of the thermohaline structure of the ocean reveals that the isopycnal lifting–lowering tends to diffuse vertically the main thermocline. The impact on temperature is that the surface layer (0–200 m) becomes cooler whereas in deeper waters (from 500 to 1500 m), the ocean becomes slightly warmer. This is particularly true in the tropics, between 30°N and 30°S. However it can be demonstrated that the assimilation improves the variability in both surface currents and sub-surface temperature in the Equatorial Pacific Ocean.  相似文献

随着社会发展的专业化、技术化以及社会关系的复杂化,行政权的强化和扩张已经成为发展的趋势,这就必然要求行政自由裁量的扩张,但是这也必然导致行政处罚可能和法治精神的背离。根据授权,海事管理机构具有的海事行政处罚是一种较严厉的制裁性行政行为,其自由裁量权若被滥用必将侵犯行政相对人的权利,影响我国的航运事业的发展。本文对海事行政处罚自由裁量权存在的合理性、如何限制行政处罚自由裁量权的行使等方面加以探讨,以期有利于海事管理机构依法行政,切实保障行政相对人的合法权益,使航运更安全、使海洋更清洁,更好地为繁荣航运经济保驾护航。  相似文献

In the Mediterranean Sea, where the mean circulation is largely unknown and characterized by smaller scales and less intensity than in the open ocean, the interpretation of altimetric Sea Level Anomalies (SLA) is rather difficult. In the context of operational systems such as MFS (Mediterranean Forecasting System) or MERCATOR, that assimilate the altimetric information, the estimation of a realistic Mean Dynamic Topography (MDT) consistent with altimetric SLA to be used to reconstruct absolute sea level is a crucial issue. A method is developed here to estimate the required MDT combining oceanic observations as altimetric and in-situ measurements and outputs from an ocean general circulation model (OGCM).In a first step, the average over the 1993–1999 period of dynamic topography outputs from MFS OGCM provides a first guess for the computation of the MDT. Then, in a second step, drifting buoy velocities and altimetric data are combined using a synthetic method to obtain local estimates of the mean geostrophic circulation which are then used to improve the first guess through an inverse technique and map the MDT field (hereafter the Synthetic Mean Dynamic Topography or SMDT) on a 1/8° resolution grid.Many interesting current patterns and cyclonic/anticyclonic structures are visible on the SMDT obtained. The main Mediterranean coastal currents are well marked (as the Algerian Current or the Liguro–Provenço–Catalan Current). East of the Sicily channel, the Atlantic Ionian Stream divides into several main branches crossing the Ionian Sea at various latitudes before joining at 19°E into a unique Mid-Mediterranean Jet. Also, strong signatures of the main Mediterranean eddies are obtained (as for instance the Alboran gyre, the Pelops, Ierapetra, Mersa-Matruh or Shikmona anticyclones and the Cretan, Rhodes or West Cyprius cyclones). Independent in-situ measurements from Sea Campaigns NORBAL in the North Balearic Sea and the North Tyrrhenian Sea and SYMPLEX in the Sicily channel are used to validate locally the SMDT: deduced absolute altimetric dynamic topography compares well with in-situ observations. Finally, the SMDT is used to compute absolute altimetric maps in the Alboran Sea and the Algerian Current. The use of absolute altimetric signal allows to accurately follow the formation and propagation of cyclonic and anticyclonic eddies in both areas.  相似文献

Abstract

Among coastal management programs, most states have found the question of appropriate administrative structure difficult to cope with. The dilemma of decision trade‐offs caused by the dual governmental needs of “efficiency”; and “representation”; has led to some alternative patterns of administration. For complex issues that transcend local boundaries, the choice between trade‐offs means adopting either (a) some form of consolidated bureaucracy or (b) some system of concurrent jurisdictions. Both alternatives have their inherent benefits and disadvantages but, considering the degree of environmental complexity and array of competing interests involved in coastal resource use, the most appropriate administrative form would seem to be concurrent control, as interagency reciprocal review promotes thoroughness and broad representation. Affected both by swings in political climate and by traditional reform politics, the case of California legislation represents a conscious deliberation over administrative alternatives. After experimenting with concurrent control under Proposition 20, California reversed its legislation in 1976 by mandating the consolidation of coastal management authority into existing bureaucratic line organizations and a reduction of the coastal agency after 1979 to a planning and advisory body.  相似文献
