Observations on mucus aggregates along Sicilian coasts during 1991–1992

1995

Abstract The results of some observations on gelatinous material accumulating on the sea ground and free floating in the water column along Sicilian coasts are reported. The phenomenon showed different development patterns moving from the Tyrrherian to the Jonian coast and to the Sicilian Channel. Moreover, in 1991, mucus aggregates in the Tyrrhenian sea showed a similar structure, behaviour and origin to those observed in the Adriatic sea, whereas, in 1992, only a massive growth of metaphytic threadlike algae, more or less producing gelatinous sheaths, occurred.

Mulighetskartlegging for kystbaserte næringer i Agder

2017

I Agder er det et sterkt ønske fra kystkommunene om å tilrettelegge for blå vekst i regionen, men for å realisere dette målet er det behov for faktisk kunnskap om hvilke muligheter havet gir – og utelukker – langs hele Agder-kysten. En slik kartlegging vil være et viktig beslutningsgrunnlag for utvikling av næring knyttet til marin sektor i regionen. Dette danner bakgrunnen for prosjektet «Mulighetskartlegging for kystbaserte næringer i Agder» som er gjennomført i samarbeid mellom NIVA og Havforskningsinstituttet. Målet med prosjektet har vært å (1) Kartlegge naturgitte næringsmuligheter innenfor marin sektor langs Agderkysten, (2) Formidle kunnskap om hvilke muligheter havet gir – og utelu…

Bathymetric estimation using MERIS images in coastal sea waters.

2007

Bathymetric estimation using remote sensing images has previously been applied to high spatial resolution imagery such as CASI, Ikonos, or SPOT but not on medium spatial resolution images (i.e., MERIS). This choice can be justified when there is a need to map the bathymetry on large areas. In this letter, we present the results of the bathymetry estimation over a large known area, the Gulf of Lion (France), expanding over 270times180 km

Systems Approach to Eastern Baltic Coastal Zone Management

2020

Relying on the results of multivariate analysis of the re-analysis case studies from the BaltCoast project, specific features of integrated coastal management (ICM) approaches in Estonia, Latvia, Lithuania, and the Kaliningrad Oblast of the Russian Federation are highlighted in this paper. Eleven Eastern Baltic ICM case studies have been re-analyzed in-depth, which was the main focus of the present paper, covering a wide range of coastal landscapes, themes, policy issues, and ICM approaches. Five principal components explaining 84.86% of the total variance of ICM factor scores have been elicited by calculating rotation sums of squared loadings: (1) Stakeholder Involvement

Uptake of chlorohydrocarbons from soil by lipid-containing semipermeable membrane devices (SPMDs)

1998

Chlorohydrocarbons (CHCs) were surveyed in contaminated lake shore soil in Central Finland with polyethylene membranes containing synthetic triolein (SPMDs). High levels of hexachlorobenzene (HCBz) and PCBs were found in a significant number of the SPMDs exposed 28 days to 35 soil sampling locations along the 350 meter long shoreline. Distributions of HCBz and PCBs were different as demonstrated by two maximas of HCBz and four maximas of PCBs observed. Soil was also analyzed at selected locations for concentrations of CHCs, organic carbon (OC) and moisture. Steady state environmental fate modeling and simple equilibrium partition estimates based on analytical results both gave the same stea…

Assessing Coastal Sustainability: A Bayesian Approach for Modeling and Estimating a Global Index for Measuring Risk

2013

Integrated Coastal Zone Management is an emerg- ing research area. The aim is to provide a global view of dif- ferent and heterogeneous aspects interacting in a geographical area. Decision Support Systems, integrating Computational Intelligence methods, can be successfully used to estimate use- ful anthropic and environmental indexes. Bayesian Networks have been widely used in the environmental science domain. In this paper a Bayesian model for estimating the Sustainable Coastal Index is presented. The designed Bayesian Network consists of 17 nodes, hierarchically organized in 4 layers. The first layer is initialized with the season and the physiographic region information. In the second la…

The Impact of Driving Forces and Protection Policies on Future Coastal Landscapes: A Case Study of Latvia

2011

Landscapes and related land cover changes are essential elements of sustainable coastal zone management in Europe and in Latvia. The issue of landscape protection, management and planning was promoted as a result of the adoption of the European Landscape Convention (2000), while the Recommendations concerning the Implementation of Integrated Coastal Zone Management were adopted by the European Community (2002) to address land use issues. The Recommendations also emphasise the need to recognise the threat to coastal zones posed by Climate Change. This paper aims to contribute to the enhancement of landscape and coastal zone management policies by addressing the changes in coastal landscapes.…

Boulder dynamics in the Favignana Island coastal zone (Egadi Archipelago, Central Mediterranean)

2016

Boulders disjoined from platform edges or accumulated in the nearshore are frequently transported and deposited in the backshore as a consequence of tsunamis and high-magnitude storm waves. We investigate this process in the Favignana Island (Egadi Archipelago) coastal zone by integrating geological and morphological data with numerical hydrodynamic analysis and radiocarbon dating. Boulders and sockets are detected in proximity to the shorelines of Punta Faraglione and Punta Fanfalo, which are located in the NW and SE sectors of the Favignana Island, respectively. They are scattered on the rocky platform as isolated blocks or in small groups that, together, form a discontinuous berm. The la…

Coastal zone water quality: Calibration of a water-turbidity equation for MODIS data

2013

AbstractA nephelometric turbidity algorithm has been specifically calibrated for coastal waters in Sicily. To this purpose, intensive field campaigns were performed in July, August and September 2008. Measurements were collected in situ in three different gulfs. Statistical analysis suggests that field data should be spatially grouped but temporally separated; hence, new calibration parameters have been proposed.Turbidity retrieved by applying the algorithm using literature coefficients and the ones calibrated in situ are shown and compared. The comparison demonstrated that a specific calibration was necessary for quantitatively monitoring turbidity in Sicilian gulfs.
