We demonstrated that oral intake of water by two calanoid copepods, Pseudodiaptomus annandalei and Eurytemora affinis takes place and has implications for their ecotoxicology. In the first experiment, copepods were exposed to a dyed medium, which allowed us to visually examine the possibility of water ...
Halving per capita food waste and reducing food losses along production and supply chains is one of the objectives fixed by the United Nations among the Sustainable Development Goals (SDGs). This study employs a system-wide modelling approach, to simulate economic impacts of households' food waste reduction ...
The importance of the maritime vehicles makes necessary the implementation of systems capable of ensure the safety and security. This paper presents an analysis on Automatic Identification System (AIS) data processed with Interacting Multiple Model (IMM) filter in order to help trajectory data analysis ...
Global Navigation Satellite Systems (GNSS) play a fundamental part on the maritime navigation. Beyond positioning, GNSS is key for the operation of multiple interfaces on the bridge of a ship, compromising the skipper skills to perform traditional navigation. Jamming attacks have been recognized as ...
The growth in minor port projects along India's coastline due to burgeoning investor interest and the complete freedom given by the governments to private entrepreneurs to develop and operate these ports have led to several environmental and social costs. Activities around ports such as dredging, cargo ...
Radio communication in Indonesia has developed quite well. However there are still many problems in the use of radio frequency channels although actually it has been regulated by the government. Radio channels for meritime and aviation for example, they both have their own dedicated frequencies so that ...
Japan Aerospace Exploration Agency (JAXA) has some instruments aboard satellites for understanding of marine context. Two satellite-based automatic identification system (AIS) receivers, named SPace-based AIS Experiment 1 (SPAISE1) on the Small Demonstration Satellite-4 (SDS-4) and SPAISE2 on the Advanced ...
Biofouling is an extensively studied problem that results in significant economic and environmental loss. Underwater structures such as ships and pipelines will be subjected to the settlement of marine fouling organisms and then suffer from ship fouling after immersed in seawater. Some marine lives ...
The relation of the territorial planning with the economic perspective is analyzed with the current components of the province of Santa Elena. In this project, the demographic aspects are identified as well as the physical environment, the natural risks and the transportation system. There is also a ...
Mapping for terrestrial ecosystem service has exponentially soared in recent years, which provides a reliable theoretical foundation for acknowledging functions, valuation and management of various kinds of ecosystem services. This study was conducted by collecting peer reviewed papers from 2000 to ...
In Sri Lanka, there are many recurring natural hazards like floods and landslides, which often turn into crucial disasters. Therefore, there is a worldwide necessity to initiate measures to reduce disaster risk as emphasized on the Sendai Framework for Disaster Risk Reduction. In this process, Multi-Hazard ...
For deep marine aquarium applications, this study introduced how to design expandable optical kits for LED aquarium lights to help the artificial breeding corals for indoor aquaculture. In this field, the LED lights must provide strong spotlight effect and higher light intensity for coral growth. It ...
For the purpose of maritime safety, information, and surveillance, almost all sea-going vessels have to participate in the Automatic Identification System (AIS). This system serves as a cooperative VHF-radio exchange of navigational and ships' information. Since AIS broadcasts self-declared information, ...
Dissolved oxygen of aquaculture is an important measure of the quality of culture environment and how aquatic products have been grown. In the machine learning context, the above measure can be achieved by defining a regression problem, which aims at numerical prediction of the dissolved oxygen status. ...
Quad-polarization Synthetic Aperture Radar (SAR) imagery can be well used to identify bivalve beds on dry-fallen intertidal flats and to investigate radar backscattering mechanisms on exposed sediments. In this study, a general classification approach to use spaceborne SAR data to distinguish sediment ...
Coastal aquaculture sea areas is of great significance to monitor these aquaculture sea areas through the means of a remote sensing technology. The images after fusion are provided with both the high-resolution feature of panchromatic images and the spectral characteristics of multi-spectral images, ...
Marine spatial planning (MSP) has been proposed to facilitate the sustainable use of oceans. To implement MSP in coastal zones, we need to understand the current status of aquaculture, in order to plan for its future. In Japan, coastal aquaculture is based on fishery rights, but it is hard to establish ...
Using Landsat 8 OLI, GF-1, GF-2 and ALOS satellite images, the distribution of aquaculture in 2010-2018 in Sansha Bay were extracted through SVM and the spatial and temporal changes of aquaculture area were detected. Next, analyze the impact of the spatial changes on local water quality which was evaluated ...
AUV has gained more and more attention with the growing importance of the ocean. The visual intelligence extends the sensing ability of the AUV. Prior work on visual intelligence of AUV mainly focuses on the object classification and serving areas underwater. Instead, we focus on a better understanding ...
