To date, the principal assessment for the Loggerhead sea turtle (Caretta caretta) distribution in the Mediterranean Basin is given by beaches nests along the coasts. The Eastern Mediterranean Sea has been revealed an important foraging area for this protected species but temporal trends of its spatial distribution and anthropogenic threats are lacking. This study shows that the employment of ferry as platform of observation would represent a valid tool for monitoring Loggerhead sea turtle in remote marine area, and to pinpoint important areas for the conservation and assessment of the species. The results of the present study confirm the previous hypothesis of the areas selected by the species, which are neritic areas in the northern/middle Adriatic Sea and oceanic areas in the Ionian Sea.
迄今为止,对地中海盆地红海龟(Caretta Caretta)分布的主要评估是根据海岸沿岸的海滩巢穴给出的。东地中海已被揭示为该受保护物种的重要觅食区,但缺乏其空间分布和人为威胁的时间趋势。研究表明,利用轮渡作为观测平台,可以有效地监测偏远海域的红海龟,并为该物种的保护和评估确定重要区域。本研究的结果证实了以往物种选择区域的假设,即亚得里亚海北部/中部的浅海地区和爱奥尼亚海的海洋地区。

Social Media for Social Species: A case study on the behavioural transitions of bottlenose dolphins (Tursiops truncatus) in the presence of tourism, Montenegro, South Adriatic 社会物种的社交媒体:南亚得里亚海黑山旅游业中宽吻海豚(Tursiops truncatus)行为转变的案例研究

Interactions between touristic vessels and cetaceans are increasing. Ecotourism, whale watching tours or the increasing economic power of the industry have all contributed to the current situation. Recent tourism studies have made cases for both short and long-term changes for targeted cetacean populations. Short-term changes refer to behavioural responses as a result of marine vessel movements where vocalisation variation and increased horizontal and vertical dive intervals have been observed. Investigating behavioural transitions of bottlenose dolphins in the absence and presence of tourism vessels, we modelled the impacts in control and impact chains, making a case for social media use to increase scientific data collection in other areas of research. In the presence of tourism, increased diving behaviours could relate to increased vessel avoidance whilst increased group cohesive behaviours may be mistaken for tighter group formations in the case of milling and resting behaviours within closer proximity to vessels. Social media searches within a two-week period using a hashtag tracking website yielded a 26.5% success rate of usable posts for scientific data. Although it is not possible to relate short-term changes in behavioural transitions to long-term changes in behavioural budget, it is evident tourism can elicit strong behavioural responses. In the knowledge that guidelines and mitigation strategies can often be ignored or take years to be implemented, we suggest using touristic habits to our benefit. Ultimately this novel way of citizen science would contribute to implementing appropriate conservation strategies, resulting in stricter regulations regarding marine vessel traffic in cetacean hotspots.
旅游船只和鲸类之间的互动正在增加。生态旅游、观鲸之旅或该行业日益增长的经济实力都促成了目前的局面。最近的旅游研究为目标鲸类种群的短期和长期变化提供了案例。短期变化是指由于海洋船只运动而引起的行为反应,其中观察到发声变化和水平和垂直潜水间隔的增加。研究了宽吻海豚在没有和有旅游船只的情况下的行为转变,我们模拟了控制和影响链的影响,为社交媒体的使用提供了一个案例,以增加其他研究领域的科学数据收集。在旅游业存在的情况下,增加的潜水行为可能与增加的船只回避有关,而增加的群体凝聚力行为可能被误认为是更紧密的群体形成,在靠近船只的情况下,铣磨和休息行为。在两周的时间里,使用标签跟踪网站进行社交媒体搜索,获得科学数据可用帖子的成功率为26.5%。虽然不可能将行为转变的短期变化与行为预算的长期变化联系起来,但很明显,旅游可以引起强烈的行为反应。鉴于指导方针和缓解战略往往会被忽视或需要数年时间才能实施,我们建议利用旅游习惯来造福我们。最终,这种公民科学的新方式将有助于实施适当的保护策略,从而对在鲸类热点地区的海上船只交通制定更严格的规定。

The promise of machine learning in the Risso’s dolphin Grampus griseus photo-identification Risso海豚grpus griseus照片识别中机器学习的前景
R. Maglietta, A. Bruno, V. Renó, G. Dimauro, E. Stella, C. Fanizza, Stefano Bellomo, G. Cipriano, A. Tursi, R. Carlucci
Photo-identification (photo-ID) studies are strategic to fill the gap of knowledge of data deficient species such as Risso’s dolphin. Unfortunately, the photo-ID process is very time consuming and strongly depends on the user-ability. Some photo-ID algorithms are available, which can, automatically or semi-automatically, find the closest match between the dolphin in the query and a catalogue of previously sighted dolphins. However the limitation of these algorithms is that in any case they will return a prevision of the dolphin identity, in other words these can not identify the individuals never sighted before, i.e. unknown dolphins. Hence the automation of the photo-ID process through the use of innovative algorithms is still needed. In this paper the opportunity of employing machine learning strategies for the automated photo-ID of Risso’s dolphin is investigated. In particular the performances of RUSBoost algorithm result to be very good in identifying the unknown dolphins, even if in general these depend on the available data for training the model. Experimental results highlight the great potential of machine learning in the automation of photo-ID process, as well as focus on the need of collecting more and more data in order to perform a more effective data analysis.
照片识别(photo-ID)研究是填补数据缺乏物种(如Risso海豚)知识空白的战略。不幸的是,照片识别过程非常耗时,而且很大程度上取决于用户的可操作性。一些照片识别算法可以自动或半自动地找到查询中的海豚与以前见过的海豚目录之间最接近的匹配。然而,这些算法的局限性在于,在任何情况下,它们都会返回海豚身份的预览,换句话说,这些算法无法识别以前从未见过的个体,即未知的海豚。因此,仍然需要通过使用创新算法来实现照片识别过程的自动化。本文探讨了采用机器学习策略进行里索海豚照片自动识别的可能性。特别是RUSBoost算法在识别未知海豚方面的表现非常好,即使通常这些依赖于训练模型的可用数据。实验结果突出了机器学习在照片识别过程自动化中的巨大潜力,同时也强调了为了进行更有效的数据分析,需要收集越来越多的数据。

Metrological Aspects in Approximate Computing: Fourier Transform in Polluted Water Spectroscopy 近似计算中的计量方面:污水光谱中的傅立叶变换
A. Lay-Ekuakille, P. Visconti, S. Maggi, G. Passarella, D. Bruno
Environmental measurements need high accuracy and precision for delivering results necessary for authorities for making decisions. In particular, for water characterization, it is necessary to perform fast analysis in order to delivery immediate results, especially in online conditions. To do that, in some circumstances it is compulsory to accept deliberate low accuracy and precision as compromise for quick results. Approximate computing could be an innovating approach on the proviso that results should be realistic. This research illustrates findings regarding application of approximate computing in the field of spectroscopy measurements related to water characterization using an experimental instrumentation based on interferometry and spectroscopy.
环境测量需要高精度和精密度,以提供当局决策所需的结果。特别是,对于水的表征,有必要进行快速分析,以提供即时结果,特别是在在线条件下。要做到这一点,在某些情况下,必须接受故意降低准确性和精度作为快速结果的妥协。近似计算可能是一种创新的方法,但前提是结果应该是现实的。本研究说明了近似计算在光谱测量领域应用的发现,这些测量与水的表征有关,使用基于干涉测量和光谱的实验仪器。

Multi-GNSS Single Frequency Precise Point Positioning 多gnss单频精确点定位
A. Innac, S. Gaglione, A. Angrisano
Single Frequency-Precise Point Positioning (SF-PPP) processing strategy is a hot topic in GNSS context, owing to the advantages of a stand-alone, accurate and cost efficiency positioning. However, the existing SF-PPP methods can be hardly implemented for high-precision applications due to the large error sources that affect accuracy and converge time of PPP solution. For this aim, the paper proposes a SF-PPP approach based on the processing of code and carrier phase measurements from multi-GNSS constellation. The algorithm is tested using a static data collection carried out in an open-sky scenario. Results show a decimeter level accuracy on horizontal and vertical components of the position.
单频精确点定位(SF-PPP)处理策略以其独立、准确和经济的优势成为GNSS领域的研究热点。但是,现有的SF-PPP方法存在较大的误差源,影响PPP解决方案的精度和收敛时间,难以实现高精度应用。为此,本文提出了一种基于多gnss星座编码处理和载波相位测量的SF-PPP方法。该算法使用在开放天空场景中进行的静态数据收集进行测试。结果表明,在水平和垂直分量上的位置精度达到分米级。

Seawater density measurements in the temperature range between 278.15 K and 308.15 K at ambient pressure 在278.15 K至308.15 K温度范围内的海水密度测量
R. Romeo, S. Lago, P. A. Giuliano Albo, M. Le Menn
Seawater density has a great importance in the oceanographic science, since it can be used for salinity determination, if density is known with the necessary accuracy. For that reason, a review of the methods for density measurements suitable for seawater measurements is presented. Furthermore, in this work standard seawater density is measured at different practical salinities (from 9.997 to 37.999) in the temperature range between (278.15 to 308.15) K at ambient pressure. Measurements are carried out by means of a vibrating tube densimeter and following the substitution method (alternating samples of seawater and ordinary water). Besides, an accurate analysis of the density uncertainty has been performed, obtaining an expanded uncertainty of 0.004%. Measurements are carried out and compared with density results given in the literature, performed with the same technique.
海水密度在海洋学中具有非常重要的意义,因为如果密度已知并具有必要的准确性,就可以用来测定盐度。为此,本文综述了适用于海水测量的密度测量方法。此外,在环境压力(278.15 ~ 308.15)K的温度范围内,测量了不同实际盐度(9.997 ~ 37.999)下的标准海水密度。测量是通过振动管密度计和替代法(海水和普通水交替取样)进行的。此外,对密度不确定度进行了精确的分析,得到了0.004%的扩展不确定度。用同样的技术进行测量,并与文献中给出的密度结果进行比较。

IoT for Buoy Monitoring System 物联网浮标监测系统
S. Pizzo, Aniello De Martino, Giancarlo De Viti, R. L. Testa, Giuseppe De Angelis
The Internet of Things (IoT) is the recent way to join low-cost hardware and cloud computing, in order to manage a network of physical devices and their data collection. During the last years the number of devices connected to IoT is dramatically increased, as well as, the number of webservices which allow to collect and manage the data. Most of these services are free for personal use, and low-cost for commercial purposes. In this work, the IoT technology was employed to monitor the health status of maritime signals, such as buoys, seamarks, beacons, etc. The developed system allows to react swiftly and efficiently if a problem occurs, in order to preserve both the safety of navigation and the signals integrity. Furthermore, the developed hardware equipment is low-cost as well as the webservices employed to notify possible problems. The system was, initially, developed to follow the position of a buoy using a GNSS device for this reason, even now, the system name is "Buoy Monitoring System" (BMS). Specifically, the paper describes the system design, its realization and the results obtained in terms of reliability; the case study regards all light maritime signals that operate in the Taranto harbor.
物联网(IoT)是最近将低成本硬件和云计算结合起来的一种方式,目的是管理物理设备网络及其数据收集。在过去的几年中,连接到物联网的设备数量急剧增加,以及允许收集和管理数据的网络服务的数量。这些服务大多数对个人使用是免费的,而对商业用途则是低成本的。在本工作中,采用物联网技术对浮标、海标、信标等海上信号的健康状态进行监测。开发的系统可以在发生问题时迅速有效地做出反应,以保证航行安全和信号的完整性。此外,开发的硬件设备成本低,以及用于通知可能出现的问题的web服务。因此,该系统最初是为了使用GNSS设备跟踪浮标的位置而开发的,直到现在,该系统仍被称为“浮标监测系统”(buoy Monitoring system, BMS)。具体介绍了系统的设计、实现以及在可靠性方面取得的成果;本案例研究涉及在塔兰托港运行的所有海上信号灯。

Magdalena Korsachka, J. Marinski, Veronika Andrea, C. Stylios
The increased human activity and uncontrolled pressure on ports and their surroundings has led to their gradual coastal erosion and environmental degradation [1] . The sustainable development of sea ports is highly dependent on the planning of environmental management policies and strategies which should be based on financial, environmental and social factors in line with the legal frame and technical requirements for each case study. Towards effective planning it is crucial to incorporate environmental monitoring systems [2] . However, even though the Balkan Mediterranean ports have already established integrated systems for environmental management, only a minority of the port authorities are able to operate environmental monitoring systems in terms of efficient cooperation and networking with other port operators and decision makers of the surrounding areas. Thus, the port of Bourgas is inevitable listed under the aforementioned cases.
人类活动的增加和对港口及其周围环境的不受控制的压力导致其海岸侵蚀和环境退化逐渐加剧[1]。海港的可持续发展高度依赖于环境管理政策和战略的规划,这些政策和战略应以财政、环境和社会因素为基础,并符合每个案例研究的法律框架和技术要求。为实现有效规划,纳入环境监测系统至关重要[2]。然而,尽管巴尔干地中海港口已经建立了环境管理的综合系统,但只有少数港口当局能够在与周围地区的其他港口经营者和决策者进行有效合作和联网方面操作环境监测系统。因此,布尔加斯港不可避免地列在上述情况下。
