The California Department of Navigation and Ocean Development (DNOD), responsible for shoreline protection within the state, was particularly aware of the lack of coastal wave statistics to support their beach erosion program. As a direct result of the 1974 ASCE-sponsored New Orleans Conference on Ocean Wave Measurement and Analysis, discussion was initiated within DNOD and then with the Scripps Institution of Oceanography (SIO) at La Jolla, on the feasibility o"f establishing a regional wave monitoring network for California. The initial specification presented by DNOD was for a 200-station network reporting directional wave spectra twice daily for a period of ten years. SIO ocean engineering personnel responded with a system concept employing low-cost pressure transducers hardwired to shore with a dialup telephone data gathering link to a central station. The initial cost estimates appeared attractive when compared with Corps of Engineers experience as reported in Peacock (1974). As a result, a small program was funded in February 1975 at Scripps to demonstrate critical hardware items through the breadboard stage. With the successful completion of this work, additional funds were allocated by DNOD as matching funds for a California Sea Grant Project. Th_e first station in the network began operation on 3 December 1975 at Imperial Beach, California. A second station was added at Ocean Beach (San Diego) on 27 March 1976, a third at SIO (La Jolla) on 18 May 1976 and the fourth at Oceanside, California on 2 June 1976. The locations of these initial stations are shown in Figure 1. Considerable effort has been directed during the past 10 years toward the development of numerical models to predict deep-water wave conditions from meteorological data. Reasonable results have been obtained and sufficient accuracy achieved to allow routing of both commercial and military ship traffic.

Abstract. A modelling system for the Adriatic Sea has been built within the framework of the Mediterranean Forecasting System Pilot Project. The modelling system consists of a hierarchy of three numerical models (whole Mediterranean Sea, whole Adriatic Sea, Northern Adriatic Basin) coupled among each other by simple one-way, off-line nesting techniques, to downscale the larger scale flow field to highly resolved coastal scale fields. Numerical simulations have been carried out under climatological surface forcing. Simulations were aimed to assess the effectiveness of the nesting techniques and the skill of the system to reproduce known features of the Adriatic Sea circulation phenomenology (main circulation features, dense water formation,flow at the Otranto Strait and coastal circulation characteristics over the northern Adriatic shelf), in view of the pre-operational use of the modelling system. This paper describes the modelling system setup, and discusses the simulation results for the whole Adriatic Sea and its northern basin, comparing the simulations with the observed climatological circulation characteristics. Results obtained with the northern Adriatic model are also compared with the corresponding simulations obtained with the coarser resolution Adriatic model. Key words.

This work presents the results of the numerical study implemented for the natural area of Lido di Spina, a touristic site along the Italian coast of the North Adriatic Sea, close to the mouth of River Reno. High-resolution simulations of nearshore dynamics are carried out under climate change conditions estimated for the site. The adopted modeling chain is based on the implementation of multiple-nested, open-source numerical models. More specifically, the coupled wave-2D hydrodynamics runs, using the open-source TELEMAC suite, are forced at the offshore boundary by waves resulting from the wave model (SWAN) simulations for the Adriatic Sea, and sea levels computed following a joint probability analysis approach. The system simulates present-day scenarios, as well as conditions reflecting the high IPCC greenhouse concentration trajectory named RCP8.5 under predicted climate changes. Selection of sea storms directed from SE (Sirocco events) and E–NE (Bora events) is performed together with Gumbel analysis, in order to define ordinary and extreme sea conditions. The numerical results are here presented in terms of local parameters such as wave breaking position, alongshore currents intensity and direction and flooded area, aiming to provide insights on how climate changes may impact hydrodynamics at a site scale. Although the wave energy intensity predicted for Sirocco events is expected to increase only slightly, modifications of the wave dynamics, current patterns, and inland flooding induced by climate changes are expected to be significant for extreme conditions, especially during Sirocco winds, with an increase in the maximum alongshore currents and in the inundated area compared to past conditions.

ABSTRACTMonitoring of water surfaces through permanent measurement of hydrodynamic and meteorological data is one of the main requirements in safe and sustainable water management. The Caspian Sea, the major surface water body in Iran, significantly affects more than 600 km of urban and industrial coastline. In the present work, an integrated marine monitoring network for the entire southern coastline of the Caspian Sea was developed. The main design concerns centered on the network measuring components and data recording, checking, filtering, gap recognition, and transferring systems. Four coastal monitoring stations were assigned, along with two regional collecting stations and one central data station for gathering, checking and delivering recorded data at different access levels. Applicable guidelines on selection of measuring devices for both shallow and deep water zones are presented herein.

Abstract. The south-eastern parts of the Adriatic Sea coastline were severely polluted by large amounts of accumulated waste material in the second half of November 2010. The waste, reported by major news agencies, accumulated dominantly during 21 November 2010 by favourable wind – ocean current transport system. In the study we analysed meteorological and oceanographic conditions that lead to the waste deposition using available in situ measurements, remote sensing data as well numerical models of the ocean and the atmosphere. The measured data reveal that an intensive rainfall event from 7 till 10 November 2010, over the parts of Montenegro and Albania, was followed by a substantial increase of the river water levels indicating flash floods that possibly splashed the waste material into a river and after to the Adriatic Sea. In order to test our hypothesis we set a number of numerical drifter experiments with trajectories initiated off the coast of Albania during the intensive rainfall events following their faith in space and time. One of the numerical drifter trajectory experiment resulted with drifters reached right position (south-eastern Adriatic coast) and time (exactly by the time the waste was observed) when initiated on 00:00 and 12:00 UTC of 10 November 2010 during the mentioned flash flood event.

AbstractHydrocarbon pollution represents one of the most serious issues for the health of the extremely fragile marine ecosystem, and strategies for its monitoring have been growing in number and complexity in the last decades. Therefore, the realization of systems able to detect the presence of pollutants in the marine environment has become extremely complex, involving different figures and integrated technologies. This paper presents an innovative model for the real-time assessment of pollutants on the sea surface based on a network of autonomous underwater vehicles (AUVs), which are able to sail the sea surface, equipped with sensors capable of detecting volatile organic compounds produced by hydrocarbons. In particular, within this context, an AUV equipped with an electronic nose-like system is proposed, with the sensors employed that were characterized both on the laboratory bench and at sea. The results obtained confirmed the feasibility of the approach proposed as well as good reliability of the data acquired, confirming the likely employment of this system within an integrated marine monitoring tool.

Small Mountainous Rivers

<p>Small rivers, particularly those draining mountainous terrain, discharge disproportionately large quantities of sediment to the globalocean. Because small mountainous rivers are more susceptible to catastrophic events, they tend to discharge their sediments over relatively short periods of time, such as during floods. The impact of small mountainous rivers is especially evident on the coastal ocean, such as the Adriatic Sea where fully 75% of the estimated 145 million tons (Mt) of discharged sediment comes from rivers with basin areas smaller than 7000 km2. Within this semi-enclosed basin in the northeast of the Mediterranean Sea, of particular note are the high sediment loads of five Albanian rivers (located in the southeast), which, prior to dam construction, collectively discharged about 85 Mt yr<sup>–1</sup> perhaps much of it at hyperpycnal concentrations, which would have allowed the sediment to bypass the shelf and be deposited at greater depths. Geochemical data confirm that Albanian river sediment extends well into the southern and central Adriatic Sea. Delineating and understanding the flux and fate of Adriatic Sea sediments may be best facilitated through the reanalysis of existing river datasets and the acquisition of new river data, particularly during periodic floods, high-resolution seismic profiling coupled with sitespecific coring, as well as application of integrated ocean-sediment numerical models</p>

Brooksia lacromae sp. nov. is described from zooplankton material collected at a marine monitoring station in the South Adriatic in the autumn of 2014. The description of both solitary and aggregate forms is given along with 18S rRNA and mitochondrial cox1 sequence data that provides strong evidence that both forms belong to the same species. The described species is morphologically markedly different from B. rostrata (Traustedt, 1893) and B. berneri van Soest, 1975, previously the only two species in the genus Brooksia. Genetic analysis based on 18S rRNA gene confirmed distinctness of B. lacromae sp. nov. from B. rostrata (1.5% uncorrected pairwise distance). The appendicularian Fritillaria helenae Bückmann, 1924, so far known from the Atlantic only, was found in the same samples as B. lacromae sp. nov. Co-occurrence of B. lacromae sp. nov. with an Atlantic appendicularian suggests an Atlantic or Western Mediterranean origin for this new taxon.
