The use of biomarkers in the assessment of the marine environmental status offers an integrated approach to the effects caused by diverse pollutants. This article compiles and analyzes the original research on the study of possible biomarkers in wild coastal-marine organisms from America. One of the outcomes of this review research is the need for a continuous evaluation of organisms in conjunction with the assessment of environmental vari-ables and the levels of pollutants that may be found in any ecosystem. It is well stated that the use of biomarkers is a practical tool for the environmental management; however, some limitations apply and there are several questions in regards to specificity, sensibility, usability, replicability, and interpretation to be solved, yet. Along the American continent, multiple biomarkers have been used to evaluate specific pollutants or highly impacted zones at marine-coastal environments. The most commonly used organisms are fishes and bivalves and they have been also extensively used in marine turtles. In regards of the type of biomarkers, plenty of authors integrate biomarkers from different groups, sorted in this review as biometric biomarkers (morphologic and corporal in-dexes), histological biomarkers (for tissues), molecular biomarkers (genetic) and biochemical and physiological biomarkers (both at the cellular and molecular levels). Following this classification, the most used biomarkers were biochemical and physiological biomarkers, due to the great advantages and information that they provide. It is of utmost importance to set guidelines and referenced threshold values for each biomarker to allow the early environmental diagnosis and integrated evaluation of harmful pollutants effects. Keywords: Biomarkers, environmental assessment, America.

In Colombia, in order to meet the challenges of coastal marine management and responding to international commitments, it was adopted in 2000 the “National Environmental Policy for the Sustainable Development of Ocean Spaces and Coastal and Insular Zones of Colombia - PNAOCI ”, which has an ecosystem approach and as a conceptual framework, the integrated management of coastal zones -MIZC (or integrated coastal management - MCI / integrated coastal management - GCI), seeking to balance environmental protection and economic development, to contribute to the Physical ordering of the territory (Territorial Ordering), from the environmental ordering. For this, criteria were defined to guide the definition of the coastal zone in the country and spatial units (Coastal Environmental Units – UACs, acronym in Spanish) were delimited, as continuous geographical areas, involving land and sea space, with clearly defined ecosystems, which they require a unified visualization and management that brings together local and subregional territorial entities; in addition to consolidating over 20 years, a conceptual, political, regulatory, technical and operational support. In the legal context, as of Law 1450 of 2011, the generation of normative support regarding the UACs and the Plans for the management and integrated management of coastal environmental units (POMIUAC, acronym in Spanish) was promoted, as a planning instrument (Decree 1120 of 2013, compiled in Decree 1076 of 2015); Likewise, based on practical cases, a methodological framework was built embodied in a technical guide for the preparation of the POMIUAC, adopted by Resolution 768 of 2017. On the other hand, although the advances in the coastal marine environmental regulation in Colombia are oriented under the MIZC, given the similarities in terms of definition, spatial scope, scope and methodology, that they have with marine spatial planning (PEM), it can be said that these processes developed in Colombia under the MIZC scheme contribute to the development of the PEM concept In the country, and in the opposite case, practical EMP exercises that are addressed could complement the advances that the country has made in this area under the policy and regulatory framework that supports it.

Ecologically Sustainable

The impacts of human-induced changes in coastal environments on shellfish farming need to be mitigated. Suspended farming species, such as oysters, greatly impact planktonic communities and benthic environments via filter feeding and bio-deposition. To more effec-tively manage coastal environments and achieve ecologically sustainable shellfish farming, interactions between coastal marine environments and aquaculture activities need to be properly assessed. We examined interactions between coastal biogeochemical environments and suspended oyster farming in Shizugawa Bay of northeastern Japan. We found that particulate organic matter (POM) produced at the oyster farm (e.g., exfoliated periphyton and/or oyster feces) locally increased the concentrations of chlorophyll a and daytime dis-solved oxygen in the bottom layer. Based on the estimated budget of POM at the bay scale, the oyster feeding rate was a couple of orders of magnitude lower than the net primary production and POM inputs at the bay boundaries (e.g., offshore and in rivers). The rela-tively high exposure of the bay and high seawater mixing rate may explain the lack of mac-roscale environmental impacts of oyster cultures at the bay scale. We also found that despite the oligotrophic environment, the oyster growth rate was higher in the bay, compared with previous estimates in other coastal areas. To understand the mechanisms sustaining the production of phytoplankton and oysters, further examinations from the perspective of nu-trient cycling in the bay are required.

AbstractThe coastal marine automated observing station (CMAOS) is a facility built on the coast or island, collecting time series of ocean environment variables such as marine hydrological and meteorological parameters. This article introduces the general progress of CMAOS in China. The greatest demand for CMAOS is marine disaster forecasting and early warning to assist decision making and to protect the marine ecological environment. After more than half a century's efforts, China has established a network of CMAOS covering the coastal areas of China, which in real time acquires marine environmental information. The core of CMAOS is the marine automated observing system (MAOS), which integrates ocean sensors, a data collector, and a data reception processor. Currently, the MAOS is in its third generation of development and will follow the trend of unmanned, intelligent, and multifunctional systems. With the continuous implementation of relevant planning of an ocean observing network in China, the layout of CMAOS will be further optimized, the observed parameters will be more comprehensive, and the measuring means will be more abundant.

Monitoring Activity

The polycyclic aromatic hydrocarbons (PAHs) are ubiquitous organic compounds of global concern. They pres-ent mutagenic and carcinogenic characteristics, in addition to a wide variety of other adverse effects in the or-ganisms. They are widely distributed in marine environments, implying several health risks for both ecosystems and public health. Therefore, require constant monitoring and tailoring of preventive measures for their control. This review is based on the PAHs original research within coastal-marine environments published along the past ten years in America, considering the main environmental matrix such as sediment, water, organisms, and air. The review shows an outstanding PAHs monitoring activity led by USA and Mexico –at all matrix-, followed by Argentina, Brazil and Chile which demonstrate a rising environmental concern on these compounds, focused in highly anthropized areas. The present data for South America is still scarce, including many areas with null information. This review demonstrates that along all the continent and all matrixes, detectable concentrations of PAHs from multiple sources are reported, with levels ranging from minimum to extremely high. Keywords: Polycyclic aromatic hydrocarbons (PAHs), marine environments, America.
