Background and Theoretical Foundations: Since the 1980s, ocean fertilization has attracted much attention among various methods of climate engineering. Some foreign researchers have examined ocean fertilization from environmental, legal, and commercial perspectives. since 2007, as the London Convention / Protocol regulates ocean fertilization, and then with the adoption of the 2013 Amendment to the London Protocol on this technology, Legal research in this area has been Increased. Although the ocean fertilization process has not yet been widely operated and remains at a limited experimental level, but legal research has been written specifically to examine the conventional position of this technology. The present article aims to explore ocean fertilization technology as one of the methods to deal with global warming, to examine its potential environmental benefits and challenges, and to examine the approach of the principles of international environmental law to this challenging technology. Methodology: Data collection of this research is library method and the procedure is descriptive analytical; Accordingly, after describing the process of ocean fertilization, it is most important environmental consequences have been studied, and finally, how international environmental law has dealt with this emerging technology has been analysed and Finally, we analyze this emerging technology in the context of the principles of international environmental law. Findings: By strengthening the biological pump of the ocean, ocean fertilization as one of the new ways to deal with climate change, seeks to increase the absorption of carbon dioxide by the ocean and ultimately deal with global warming. Countering global warming, increasing of the fish resources, promote marine scientific research and the carbon trade have been cited as potential benefits of ocean fertilization, but in addition to these benefits, the possibility of environmental problems such as ocean acidification, toxic algal blooms and anoxia is not out of the question. The transboundary environmental effects of ocean fertilization — whether in the internal waters It is a testament to the need to intervene of international environmental law to regulate this technology and its consequences. Therefore, in the present article, we intend to examine the role of the principles of international environmental law in responding to issues arising from the ocean fertilization and its regulation and elimination of its treaty gaps. Conclusion: The ocean fertilization can be described as a double edged sword that on the one hand is able to overcome one of the most important environmental challenges of the present age, namely global warming and consequently climate change, and on the other hand is the cause of marine environmental damage. First of all, the findings of the present paper show that, there is insufficient scientific certainty about the environmental consequences of ocean fertilization, and further st
背景与理论基础:自20世纪80年代以来,海洋施肥在各种气候工程方法中备受关注。一些外国研究人员从环境、法律和商业的角度研究了海洋施肥问题。自2007年以来,随着《伦敦公约/议定书》对海洋施肥进行监管,以及2013年《伦敦议定书》关于该技术的修正案的通过,这一领域的法律研究得到了加强。虽然海洋施肥过程尚未广泛操作,仍处于有限的实验水平,但已经专门编写了法律研究,以审查这一技术的传统地位。本文旨在探讨海洋施肥技术作为应对全球变暖的方法之一,研究其潜在的环境效益和挑战,并研究国际环境法原则对这一具有挑战性的技术的方法。研究方法:本研究的数据收集采用图书馆法,研究过程采用描述性分析;因此,在描述了海洋施肥过程之后,最重要的是对环境后果进行了研究,最后,对国际环境法如何处理这一新兴技术进行了分析,最后,我们在国际环境法原则的背景下分析了这一新兴技术。研究发现:通过加强海洋的生物泵,海洋施肥作为应对气候变化的新途径之一,寻求增加海洋对二氧化碳的吸收,最终应对全球变暖。应对全球变暖、增加鱼类资源、促进海洋科学研究和碳贸易被认为是海洋施肥的潜在好处,但除了这些好处之外,海洋酸化、有毒藻华和缺氧等环境问题的可能性也不是没有问题。海洋施肥的跨界环境影响- -无论是在内部水域- -这证明需要国际环境法进行干预,以管制这种技术及其后果。因此,在本文中,我们打算审查国际环境法原则在对海洋施肥及其管制和消除其条约空白所引起的问题作出反应方面的作用。结论:海洋施肥可以被描述为一把双刃剑,一方面能够克服当今时代最重要的环境挑战之一,即全球变暖和随之而来的气候变化,另一方面是海洋环境破坏的原因。首先,本文的研究结果表明,海洋施肥的环境后果缺乏科学的确定性,需要进一步的研究和实验来实现科学的确定性。其次,对直接或间接涉及这项技术的国际条约的回顾表明,《生物多样性公约》、《伦敦公约/议定书》以科学上的不确定性和需要采取预防措施为由,严重限制了海洋施肥。但他们面临着诸如非全球参与和绝对消极态度等批评。第三,在上述情况下,运用国际环境法原则来填补现有空白和完善条约文件可能非常有帮助。

Background and Objectives: Coastal physical vulnerability studies were first conducted by Gornitz in 1991 on the west coast of the Atlantic Ocean, and have since been studied extensively in other parts of the world. In this article, determining the severity of physical vulnerability of Sefidrood delta coast, identifying coastal landforms and how they deform over time are the main objectives of the research. Methods: By using the results of field monitoring, interpreting the results of remote sensing studies and digital changes of coastlines in the GIS environment, and by studying the effective criteria in the physical vulnerability of coasts such as: coast slope, type of coastal sediments, type of coastal landforms, rates Coastal line changes, physical vulnerability of Sefidrood delta coast were calculated. Findings: In The results show that the degree of physical vulnerability of Sefidrood delta coast varies in different regions. Areas leading to the western and eastern estuaries of Sefidrud River have the highest physical vulnerability and with increasing distance from the estuary to the west and east, the degree of physical vulnerability gradually decreases. Erosive coastal landforms in the area adjacent to the Sefidrood estuary have been formed as erosive terraces and sand spits have formed in the western and eastern extremities of the Sefidrud delta. Conclusion: The Sefidrood delta is affected by the erosive forces of the Caspian Sea, and the high volume of sedimentation of sandy materials produced by the Sefidrood River under the influence of coastal currents has the ability to create sedimentary landforms such as sand spits in coastal area. Achieving a physical vulnerability map of the White River Delta provides the conditions for making the right decisions in the integrated coastal zone management, and this method can be used for other coastal areas .
背景和目的:海岸物理脆弱性研究由Gornitz于1991年首次在大西洋西海岸进行,此后在世界其他地区进行了广泛的研究。在本文中,确定Sefidrood三角洲海岸物理脆弱性的严重程度,确定海岸地貌及其随时间的变化是研究的主要目标。方法:利用野外监测结果,在GIS环境下对海岸线遥感研究结果和数字化变化进行解译,研究海岸坡度、海岸沉积物类型、海岸地貌类型、海岸线变化率等海岸物理脆弱性的有效准则,计算Sefidrood三角洲海岸的物理脆弱性。结果表明:Sefidrood三角洲海岸不同区域的自然脆弱性程度存在差异。通往塞菲鲁德河西部和东部河口的区域自然脆弱性最高,随着河口向西和向东的距离增加,自然脆弱性程度逐渐降低。Sefidrud三角洲的西部和东部末端形成了侵蚀阶地和沙喷,从而形成了Sefidrud河口附近的侵蚀性海岸地貌。结论:Sefidrood三角洲受到里海侵蚀力的影响,Sefidrood河在沿岸水流的影响下产生的大量砂质物质沉积,有能力在沿海地区形成沙吐等沉积地貌。绘制白河三角洲物理脆弱性地图为海岸带综合管理决策提供了条件,该方法可用于其他沿海地区。

Background and Objectives: The Oligo-Miocene marine deposits (Qom Formation) have been widely spread in the Central Iran Zone. According to economic value of these marine deposits, this Formation studied by several researchers. While there are many differences opinion among researchers. For this reason, to solve the existing ambiguities, it is necessary to study with new tools and techniques. Therefore, the present study is the first study aimed at biostratigraphy based on calcareous nannoplankton that has been performed on all succession exposed from the Oligo-Miocene marine deposits (members a to f of the Qom Formation). Methods: The studied deposits are located in the middle part of the Central Iran Zone and more precisely in the Navab anticline (northeast of Kashan city), which has a thickness of 417 meters. Due to the location and expansion of all members in this section, it has been a very suitable area for biostratigraphic assessments comparable to world standard models. In this study, a total of 370 microscopic slides prepared from rock samples were studied to the determination of the calcareous nannoplankton and accurately separate world standard biological zones. Findings: The present study led to the identification of 72 species belonging to 18 genera of this valuable group of the planktonic micro-organisms. According to the identified index species, standard nannoplankton biozones of the NP25 and NN1-NN4 were separated from this surface section of the Qom Formation. In addition, the equivalent biozones such as CNO5-6, CNM1- CNM6 as well as zones and subzones CP19b, CN1a, b, c, CN2- CN3, which belonging to the newest biozonation patterns, were also separated in this study. Conclusion: Therefore, based on the geological time value of the separated biozones, the age of late Chattian to late Burdigalian-early Langhian was proposed for the Qom Formation in the Navab anticline section. In this study, for the first time, the important chronostratigraphic boundaries such as the Paleogene- Neogene system boundary (or Chattian-Aquitanian stage boundary) in the upper parts of sub-member "c1", the Aquitanian- Burdigalian stage boundary at the base of member "e" and Burdigalian- Langhian in the upper part of member "f", were disaggregated based on biostratigraphic criteria.
背景和目的:伊朗中部地区广泛分布着渐新世-中新世海洋沉积物(库姆组)。根据这些海洋沉积物的经济价值,几位研究人员对该组进行了研究。尽管研究者之间存在许多不同意见。因此,为了解决现有的歧义,有必要使用新的工具和技术进行研究。因此,本研究是第一项基于钙质超微浮游生物的生物地层学研究,该研究已在渐新世-中新世海洋沉积物(库姆组成员a至f)暴露的所有序列上进行。方法:所研究的矿床位于伊朗中部地区的中部,更确切地说是位于Navab背斜(卡山市东北部),厚度417米。由于该部分所有成员的位置和扩展,它一直是一个非常适合与世界标准模型相比较的生物地层学评估区域。在这项研究中,共研究了370张从岩石样本中制备的显微镜玻片,以确定钙质超微浮游生物,并准确地分离出世界标准的生物区。研究结果:本研究鉴定了这一宝贵的浮游微生物群中的18属72种。根据已确定的指数物种,NP25和NN1-NN4的标准浮游动物生物带从库姆组的该表面膜中分离出来。此外,本研究还分离出了CNO5-6、CNM1-CNM6等等效生物带,以及属于最新生物分带模式的带和亚带CP19b、CN1a、b、c、CN2-CN3。结论:因此,根据分离生物带的地质时间值,提出了纳瓦布背斜段库姆组的时代为查特晚期至布尔迪加利安晚期至朗希安早期。本研究首次根据生物地层学标准对“c1”子段上部的古近系-新近系边界(或查特-阿基坦阶边界)、“e”子段底部的阿基坦阶-布尔迪加利安阶边界和“f”子段上半段的布尔迪加良阶-朗希安阶等重要年代地层边界进行了划分。

Background and Objectives: Coral ecosystems, like other natural habitats, are under the influence of global warming. Every year we see the bleaching of corals in different parts of the world. Since the physical parameters of seawater are affected by meteorological phenomena, so in this study using ten-year data of oceanographic buoys, the effect of physical parameters of seawater including water surface temperature, salinity, acidity and electrical conductivity on the phenomenon of bleaching of branching corals in Chabahar Bay was investigated. Methods: For this purpose, the trend of multi-year data of marine parameters was determined by non-parametric Mann-Kendall test. In the next step, the Pearson correlation test showed the correlation between seawater parameters and choreographed Zooxanthellae algae color score data as a coral health index produced by the authors during long-term diving operations using the Coral Watch method. Findings: The results of this study showed that among the four parameters: water surface temperature, electrical conductivity, acidity and salinity, the highest correlation and the most effective independent variable in multivariate regression between coral health and seawater parameters is concern to EC. Conclusion: Due to the insignificance of the increasing trend of water surface temperature in previous years and the existence of a significant negative correlation at the level of 0.01 between the health status of corals and water surface temperature, fortunately, the branching corals of Chabahar Bay have been in good condition. As human and sea pollutants are controlled in the coming years. We will see the survival of this valuable ecosystem.
背景和目标:珊瑚生态系统和其他自然栖息地一样,正受到全球变暖的影响。每年,我们都会看到世界不同地区的珊瑚白化现象。由于海水的物理参数受气象现象的影响,本研究利用10年的海洋浮标数据,研究了海水的表面温度、盐度、酸度和电导率等物理参数对恰巴哈尔湾分支珊瑚白化现象的影响。方法:为此,采用非参数Mann-Kendall检验确定海洋参数多年数据的趋势。在下一步中,Pearson相关性测试显示了海水参数与编排的Zooxanthellae藻类颜色评分数据之间的相关性,该数据是作者在长期潜水作业中使用珊瑚观察方法产生的珊瑚健康指数。研究结果:本研究结果表明,在水面温度、电导率、酸度和盐度四个参数中,珊瑚健康与海水参数之间的多元回归中相关性最高、最有效的自变量是EC。结论:由于前几年水面温度上升趋势不大,珊瑚健康状况与水面温度之间存在0.01水平的显著负相关,幸运的是,恰巴哈尔湾的分支珊瑚状况良好。随着人类和海洋污染物在未来几年得到控制。我们将看到这个宝贵的生态系统的生存。
