Abstract

Introduction: While cyanobacteria and algae living in sea water are well recognized, those that are the components of aerosols are rarely the focus of scientific research, especially in the Baltic Sea region. That’s why the aim of this study was to determine whether among the identified microalgae and cyanobacteria there were any capable of posing a potential threat to human health.

Methodology & Theoretical Orientation: Bioaerosols were collected in 2015 on land and at sea on petri dished covered with f/2 culture medium and placed in six-step microbiological pollutant sampler (<1.1 μm->7 μm). In all samples the taxonomic composition and number of identified taxa were analysed.

Findings: It was found that cyanobacteria and microalgae having been identified both in the atmosphere over the sea and over land during the entire study period are omnipresent microbiological air pollutants. Some of them had been transported from remote areas, such as Gloeothece sp. - a species not typical for the Southern Baltic Sea.

Conclusion & Significance: The higher the primary production in sea water and the concentration of phytoplankton in it, the greater the diversity in terms of the microorganisms observed in the collected bioaerosol samples. Other important factors were: water temperature, accessibility of light and the amount of available phosphorus and nitrogen in the surface water. In the atmosphere over land, microorganisms dominated in aerosol particles of smaller dimensions (<3.3 µm in diameter). Over the sea, there was a reverse situation. That resulted from the fact that smaller aerosols could be better distributed over long distances. Among the identified microorganisms were species which pose a threat to human health and life. Seeing as in the surrounding air, part of the everyday environment of the human habitat, those species were incorporated into small, respirable particles, it is necessary to conduct further research.

Abstract

Introduction: The energetics of internal tides using Massachusetts Institute of Technology general circulation model (MITgcm) in the coastal waters of the extended shelf of the western Bay of Bengal (BoB) is investigated. The model open-boundaries are forced with barotropic tidal velocity components from TPXO model. The spectral estimate of density indicates that the peak estimate is associated with the semidiurnal frequency at all the depths. The baroclinic zonal and meridional components of velocity are found to be in the order of 0.3 and 0.4 ms-1, respectively in observations as well as in the simulations. The energy flux calculated using the velocity-pressure correlation is predominantly seen in zonal direction from both observations and simulations. The calculation of Richardson number reflected the presence of local mixing due to density overturning in the shelf region. The model simulation suggests that the internal tides are generated all along the shelf-slope region and maximum amount of energy propagates towards the coast. The study of seasonal variability of internal tides suggests that the magnitude of energy flux is more in November compared to other months. The model simulated energy dissipation rate infers that its maximum occurs at the generation sites and hence the local mixing due to internal tide is more at these sites. The spatial distribution of Available Potential Energy (APE) (20 kJm-2) is found to be maximum in November and minimum (14 kJm-2) in August in the northern BoB. The APE is found to be more in the north and hence the internal tide energy is more. The detailed energy budget calculations are made for different seasons and the results are analyzed in this study.

Methodology & Theoretical Orientation: The characteristics of internal tides, such as source of generation, direction of propagation and subsequent dissipation are investigated quantitatively based on their energetics. The barotropic and depth-integrated baroclinic energy equations are given by:

Findings: Model simulated spectral estimate of density and baroclinic velocity are reasonably well compared with the available in-situ observations; Potential regions of generation, propagation and dissipation of internal tides are investigated; Detailed energy budget of internal tides and its seasonal variability are examined.

Conclusion & Significance: The computations of energy flux and energy conversion of barotropic to baroclinic rate suggest that there are multiple source/sink sites in the domain. The energy conversion rate is seen between the isobaths of 500 and 1500 m. The baroclinic energy flux is perpendicular to that of barotropic which propagates toward the coast. The dissipation rate is responsible for maximum mixing over the shelf-slope region. From the spatial distribution of APE, the maximum value is pronounced in the north of the western BoB. This implies that the internal tide is more dominant over this region. The mixing due to density overturning over the continental shelf is studied through the Richardson number which causes vertical mixing.

Abstract

Rias-type bays are one of the most common coasts in Japan where aquacultures without feeding have been active. The huge tsunami hit Sanriku Coast consisting of open rias-type bays near the epicenter facing Pacific Ocean on 11 March 2011. For recovering Sanriku Coast, it is important to include sustainability in its program. Satoumi practice is defined as a human use and management of coastal seas for high productivity while maintaining high biodiversity. We studied a typical rias-type bay, Shizugawa Bay, in southern Sanriku Coast, where oyster and Undaria pinnatifida are mainly cultured. The tsunami flushed out most of all aquaculture facilities. Just after the tsunami, they deployed seed oysters which fortunately escaped from the tsunami on the sea in 2011. The oysters grew to a commercial size in ten months due to good prey condition while they needed two to three years before the tsunami because of insufficient prey condition. After long discussion among fishermen, committee for Shizugawa Bay management of fishermen’s cooperative of miyagi prefecture decided to decrease oyster culture facilities based on this experience of oyster growth. We conducted scientific researches on mapping of coastal habitats and aquaculture facilities, hydrography and material flows of nutrients, a minor element (Fe) and particulate organic matters in the bay including those from the rivers and the offshore waters. Based on these data, a physical-biological coupling model was used for calculating the number of aquaculture facilities that are suitable not only for yields but also for environments. A council for discussing on sustainable aquacultures and sound marine environments in Shizugawa Bay was established by a fishermen’s cooperative, local governments, WWF and scientists. Discussion based on scientific researches promoted sustainable aquaculture. This satoumi practice may help to realize sustainable coastal use of a rias-type bay.

Conclusion and Significance: The tsunami event gave a chance to fishermen to change their aquaculture practices to ones that are economically and environmentally sustainable through their experiences and discussions together with our scientific researches and WWF’s supports. Thanks to this change, oysters in Tokura Branch of fisheries cooperative in Shizugawa Bay obtained ASC certificate from Aquaculture Stewardship Council in March of 2016. This success story may permit to broaden such kind of Satoumi practice to other rias-type bay where aquaculture without feeding are mainly conducted.

Abstract

Purpose: The HLMRCEDZ was established on March 30, 2005. The total area is approximately 180 hectares. This area is a protected area established for the conservation of biological diversity. It starts with the protection of sea urchins and then expands to the full protection of all marine organisms. The aim of this study was to investigate the sea slug’s biodiversity and distribution in HLMRCEDZ.

Methods: A few centuries ago, naturalists and philosophers had observed and thought about the why, how, when and what issues in animal behavior. Therefore, animal behavior can be described as a branch of a long history in the history of biological research. Fourteen 50 m * 20 m bio phase areas were selected, visual strip-transects and GPS positioning were applied to search the species, body length and numbers. Record all the data and perform behavioral analysis and identification. Plymouth routines in Multivariate Ecological Research software was used to analysis the distribution.

Results: These surveys were found 8 Orders, 29 Families and 119 species, 74 species accounted for effective species and 45 species accounted of unknown species, body length between 1 mm and 80 mm, numbers from 1 to 3000.

Conclusion: The study indicated that the sea slug’s biodiversity and distribution are very high in HLMRCEDZ, especially in the sand area, 26 degrees seawater temperature and 12-15 m depth. Order Cephalaspidea have number of advantages in the sand area of 12 to 15 meters in the area of the Houbi Lake Marine Resource Protection Demonstration Zone in Kenting National Park.
