Tintinnids are an essential link between nano- and macro- planktons in the food webs of the marine environment. It is also known that tintinnids are one of themajor components of marine planktonic ciliates and has a cosmopolitan character. In the Philippine archipelago, which is recognized as a center of marine biodiversity, tintinnids checklist has not been done or published. Therefore, a checklist is presented in this study based on a compilation of previous tintinnids studies conducted at the Philippines waters. As a result of the studies done since 1941 up to present, a total of 114 taxa belonging to 14 families and 37 genera were listed. The Philippines coastal waters record a total of 50 species while the open seas document 72 species to date.

About 95% of earth living space lies deep below the ocean’s surface and it harbors extraordinary diversity of marine organisms. Marine biodiversity is an exceptional reservoir of natural products, bioactive compounds, nutraceuticals and other potential compounds of commercial value. Timeline for the development of the drug from a plant, synthetic and other alternative sources is too lengthy. Exploration of the marine environment for potential bioactive compounds has gained focus and huge opportunity lies ahead for the exploration of such vast resources in the ocean. Further, the evolution of superbugs with increasing resistance to the currently available drugs is alarming and it needs coordinated efforts to resolve them. World Health Organization recommends the need and necessity to develop effective bioactive compounds to combat problems associated with antimicrobial resistance. Based on these factors, it is imperative to shift the focus towards the marine environment for potential bioactive compounds that could be utilized to tackle antimicrobial resistance. Current research trends also indicate the huge strides in research involving marine environment for drug discovery. The objective of this review article is to provide an overview of marine resources, recently reported research from marine resources, challenges, future research prospects in the marine environment.

The oceans are a vast yet fragile environment, and one of the biggest issues scientists have to tackle today is the conservation of marine biodiversity. In 1975, to try to address the physical, chemical and biological alteration of these delicate ecosystems, 16 Mediterranean States together with the European Union, implemented the Mediterranean Action Plan (MAP). The aim was to safeguard the marine environment and promote its development in the Mediterranean basin.

Health And Well Being

The Philippines, as a tropical archipelagic country, is particularly vulnerable to environmental changes affecting coastal and marine settings. However, there are limited studies investigating how these changes are perceived by the local populations who depend directly on the marine environment for their livelihoods, health, and well-being, and who are the most vulnerable to such changes. To explore these issues, we conducted an in-home face-to-face structured survey in 10 coastal communities in Palawan, Philippines (n = 431). As part of the survey, respondents were asked to comment on how important they believed a list of 22 drivers/pressures (e.g., “land-use change”) were in affecting their local marine environment. Statistical analysis of this list using Exploratory Factor Analysis suggested the 22 drivers/pressures could be categorized into 7 discrete groups (or in statistical terms “factors”) of drivers/pressures (e.g., “urbanization,” “unsustainable fishing practices” etc.). We then used ordinary least squared regression to identify similarities and differences between the perspectives within and across communities, using various socio-demographic variables. Results suggested that among the seven identified factors, four were perceived by the local communities as making the marine environment worse, two were perceived as having no impact, and one was perceived to be making the marine environment better. Perceptions differed by gender, education, ethnicity, and study site. A subsequent survey with 16 local coastal resource management experts, suggested that public perceptions of the most critical drivers/pressures were broadly consistent with those of this expert group. Our findings highlight how aware local coastal communities are of the drivers/pressures underpinning the threats facing their livelihoods, health, and well-being. Ultimately, this information can support and inform decisions for the management of local marine resources.

Bothnian Bay

The Baltic Sea is one of the largest brackish water bodies in the world (Segerstråle 1957) with a number of basins varying from almost fresh water in the northern part of the Bothnian Bay via the more brackish conditions in the southern part to the saline waters of the Kattegat. The Baltic Sea is subject to severe environmental degradation caused by commercial and leisure activities, including fisheries, dredging, tourism, coas t a l development and land-based pollution sources. This causes severe pressures on vulnerable marine habitats and natural re- sources, and a tool for aiding marine management is therefore strongly needed. The marine landscape concept presented by Roff &Taylor (2000) is based on the use of available broad-scale geological, physical and hydrographical data to prepare ecologically meaningful maps for areas with little or no biological information. The concept, which was elaborated by Day & Roff (2000) was applied in UK waters (Connor et al. 2006) before it was adopted by the BALANCE project described here. The aim of developing marine landscape maps is to characterise the marine environment of the Baltic Sea region (the Baltic Sea together with the Kattegat) using geophysical and hydrographical parameters. Such maps can be applied, for example, to an assessment of the Baltic-wide network of marine protected areas, and thus provide a sustainable ecosystem-based approach to the protection of the marine environment from human activities, and contribute to the conservation of marine biodiversity. The BALANCE project is based on transnational and cross-sectoral co-operation with participants from nine countries surrounding the Baltic Sea as well as Norway (Fig. 1), and is partially financed by the European Union through the BSR INTERREG IIIB programme.

Sources Of Pollution

This chapter begins by looking at the role of the 1982 UN Law of the Sea Convention (UNCLOS) as the framework legal instrument on the oceans. Indeed, the UNCLOS is one of the most significant international law instruments of all time and is at the core of today's governance of the oceans. UNCLOS is a product of the time when it was negotiated, which brought together a desire to provide global stability to competing jurisdictional claims over the oceans and devise solutions to rapidly increasing rates of marine pollution. However, technological changes and increased or unforeseen sources of pollution and habitat destruction have exposed some of the Convention's limitations, which derive from a fragmented perspective of the marine environment, and a failure to address the interaction between different ocean uses and marine stressors and provide rules on the conservation of marine biological diversity. The chapter then evaluates global and regional treaty requirements, soft law instruments, and case law concerning the protection of the marine environment from various sources of pollution, and the conservation of marine living resources, with a focus on fisheries, and the protection of marine biodiversity.

This article appraises the Factors deteriorating marine environment due to violation of marine pollution laws in Pakistani waters. The environmental degradation of Pakistani waters especially in Karachi coast became a serious threat to the marine environment, marine life as well as human health and marine vessels since long for society. It is determined the level and the distribution pattern of various heavy metals in the coastal waters significantly higher than the standard values. Pollution created by a number of sources is the major contributing factor in this regard. Amongst all, the deteriorating environment in Pakistani waters warrants immediate corrective actions to control Marine Pollution in order to curtail further destruction by this menace. Many steps at Governmental and private level have been initiated however, improvement is a dream. It is rightly to mention that there is no dearth of legislation on the pollution control but implementation of the same by all the concerned agencies and cooperation by public in true letter and spirit is a dream. The prevailing environment cannot be improved without effective enforcement of existing laws in its true perspective by removing all obstacles and difficulties with creating political will of society.
