Abstract Marin, V., Moreno, M., Vassallo, P., Vezzulli, L., and Fabiano, M. 2008. Development of a multistep indicator-based approach (MIBA) for the assessment of environmental quality of harbours. – ICES Journal of Marine Science, 65: 1436–1441. Environmental pollution in harbours can have detrimental effects on the port, its users, and the surrounding environment. Despite these risks, the Italian legal framework for marine environmental quality does not apply to harbours and marinas, so monitoring is not mandatory. With the aim of supporting environmentally sound management, we propose an in

Abstract Non-Indigenous Species (NIS) are a threat to native biodiversity and ecosystem services. The European seas are known to be the recipient of several hundreds of NIS due two main origins: shipping and aquaculture. They are the focus of Descriptor 2 of good environmental status in the Marine Strategy Framework Directive. 153 NNS had been recorded along the Normandy coast in 2018. Marinas are priority sites for monitoring, being ‘hotspots’ for the NIS occurrence.

Resumen
Flushing or residence times are typically used as a first step in assessing water quality in marinas, harbours and coastal basins. Recent publications have offered guidance in relation to optimal marina basin and entrance geometries to help achieve rapid renewal. However, these guidelines have been developed for the particular case where water exchange is strongly tide-driven and are not widely applicable, particularly in micro-tidal regions. Where water renewal rates are dominated by shear-driven circulation and lateral transfer of momentum at the interface between the marina and the adjacent

Abstract A survey of water and sediment from 152 harbours, marinas and shipping channels across Canada was conducted in 1999 to determine the extent of contamination by tributyltin (TBT) prior to the total ban on its antifouling uses being phased in over the period 2003 to 2008, and to assess the effectiveness of the 1989 regulation of antifouling uses of TBT under the Canadian Pest Control Products Act. TBT was found in sediments in this survey much more frequently than in water. The main conclusion was that by 1999 the regulation had been generally effective in reducing TBT contamination in

In this paper, we take the broad definition of tsunami (‘harbour wave’) to describe oscillations in the infragravity (IG) periods (between 30 and 300s) in ports and marinas that often lead to interruption in harbour operations due to excessive vessel movements. The main processes that lead to these oscillations (also called seiches) are examined through the analysis of field measurements of water levels and currents from Western Australia. In a port or marina with lengths of the order of 500m and depths of the order of 10m, the natural oscillation periods are of the order of a few minutes.

An understanding of the relationship between the flow generators and harbor design could result in an acceptable seawater renewal into an enclosed basin. The flushing culverts located in the breakwater are the most cost-effective technique for improving water renewal in port engineering. The aim of the paper was to identify and quantify the relation between flow generators and culvert flow to propose an optimal position for the flushing culverts. Mentioned relations are important for designing and positioning the flushing culverts in marinas to achieve optimal sea exchange in the marina basin.

Resumen
Styela plicata (Lesueur, 1823) (Tunicata; Stolidobranchia; Styelidae) is a solitary ascidian with a global distribution. Until recently it had not been observed along the Mediterranean coast of Israel, but is now to be found in many harbors attached to suspended ropes and other artificial structures. In order to monitor the populations of S. plicata, we surveyed eight harbors along the Israeli Mediterranean coast. Our results show that the condition and maintenance of each harbor significantly affected the presence of S. plicata. We also characterized the microbial communities in the tunic of

Resumen
Apart from extensive infrastructure protection, modern yacht ports should primarily provide vessels with navigational safety associated with their maneuvering on the approach fairway, as well as mooring in the port aquatory. For this reason, yachts entering the harbor should have up-to-date, accurate, and reliable charts of the port and its surroundings. This article presents hydrographic surveys conducted in the National Sailing Centre (NSC) yacht port at the Gdańsk University of Physical Education and Sport (GUPES), whose aim was to define and develop unique bathymetric and navigational char

Resumen
One of the most important causes of biodiversity loss are non-indigenous species (NIS), in particular invasive ones. The dispersion of NIS mainly depends on anthropogenic activities such as maritime traffic, which account for almost half of the total NIS introduction in the European seas, as reported by the European Environmental Agency. For this reason, NIS management measures are mainly focused on commercial ports (i.e., ballast water management and Marine Strategy Framework Directive monitoring), underestimating the role of marinas and tourist harbors; these host small vessels (<20 m), s

Resumen
Alaskan ascidians are incompletely known and rarely sampled. The Smithsonian Environmental Research Center recently conducted an extensive survey of harbors and marinas for nonindigenous species at major marine traffic sites on the Kenai Peninsula and Prince William Sound in Alaska. Collections made during summer 1998 and 1999 included 12 species of ascidians, one of which is a new species of Distaplia, D. alaskensis. We consider it indigenous, though it could be cryptogenic because it was collected only from marina floats and no neighboring natural subtidal areas have ever been sampled. All t

Resumen
The flushing characteristics of a newly constructed marina were determined from a comprehensive field study which included a dye dilution experiment together with measurements of barotropic and baroclinic forcing parameters. The results to be presented show that the major exchange process in this particular marina is a baroclinic circulation, and that the exchange rate is controlled by the harbour entrance geometry.

Resumen
Mangrove vegetation, a threatened and unique inter-tidal ecosystem, harbours a complex and largely unexplored bacterial community crucial for nutrient cycling and the degradation of toxic pollutants in coastal areas. Despite its importance, the bacterial community composition of the gray mangrove (Avicennia marina) in the Red Sea coastal regions remains under-studied. This study aims to elucidate the structural and functional diversity of the microbiome in the bulk and rhizospheric soils associated with A. marina in the coastal areas of Ras Alshabaan-Umluj (Umluj) and Almunibrah-Al-Wajh (Al-Wa

Resumen
A new Marina, capable of hosting up to 1,000 boats, is being constructed along the southern Tyrrhenian Sea coast of Italy. The Marina is separated from the shore by a 80 m wide channel and access to the harbour will be via a bridge designed by Santiago Calatrava. Design improvements and refinements were identified through physical and numerical model studies. This paper shows the important role of numerical and physical models in the design process of a marina. For this project the physical model study has confirmed the effectiveness of the optimised design

Resumen
Tutukaka Harbor is located on the east coast of New Zealand, approximately 140 km north of Auckland. At the head of the harbor is Tutukaka Marina which is a popular focal point for maritime recreation and an important economic driver for the area. Tutukaka Harbor is a well-known tsunami ‘hot spot’ as the irregularly shaped harbor is known to amplify incident tsunami energy due to resonance (Borrero and O’Neill, 2019). The objective of this study is to investigate a possible reconfiguration of the entrance to Tutukaka Marina to reduce the severity of tsunami induced currents. Over the years, br

Non-native ascidians have long dominated the artificial structures in southern California’s (United States) marinas and harbors. To determine the change in ascidian abundance and community composition over the last several decades, in 2019–2020 we replicated surveys from 1994–2000. We then created nMDS plots using the abundance data collected in the 1994–2000 and 2019–2020 surveys to compare the two groups. Range and average abundance per species were analyzed to determine trends and changes in ascidian community composition. Of the species used for comparison, four are native, three are crypt

Resumen
As a result of damage from the 2010 Chile and 2011 Japanese teletsunamis, the tsunami risk to the small craft marinas in California has become an important concern. This paper outlines an assessment tool which can be used to assess the tsunami hazard to small craft harbors. The methodology is based on the demand and capacity of a floating dock system. Results are provided as fragility curves and give a quantitative assessment of survivability. This tool is not exact and is provided only to give an indication as to survivability and/or failure of a floating dock system of vessels and floating c
