Received 27 October 2008, revised 9 February 2009, accepted 18 February 2009.
The physical and optical properties of an atmospheric aerosol mixture depend on a number of factors. The relative humidity influences the size of hydroscopic particles and the effective radius of an aerosol mixture. In consequence, values of the aerosol extinction, the aerosol optical thickness and the Ängström coefficient are modified. A similar effect is observed when the aerosol composition changes. A higher content of small aerosol particles causes the effective radius of an aerosol mixture to decrease and the Ängström coefficient to increase. Both effects are analysed in this paper. The parameters of the size distribution and the type of components used to represent natural atmospheric aerosol mixtures are based on experimental data. The main components are sea-salts (SSA), anthropogenic salts (WS, e.g. NH4HSO4, NH4NO3, (NH4)2 SO4), organic carbon (OC) and black carbon (BC). The aerosol optical thickness is modelled using the external mixing approach. The influence of relative humidity on the optical and physical properties of the following aerosol mixtures is investigated: (SSA & WS), (SSA & OC), (SSA & BC), (SSA, WS & OC) and (WS, OC & BC). It is demonstrated that the Ängström coefficient can be used as a rough indicator of the aerosol type.

Keywords: wave hindcast, wave measurement, winds, storms, climate change, RDCP, Baltic Sea

Received 13 November 2008, revised 4 February 2009, accepted 9 February 2009.

This work was support by the Estonian Science Foundation through grant No. 7609.
Based on wind data from the Vilsandi meteorological station and a 5-month calibration measurement with a bottom-mounted Recording Doppler Current Profiler (RDCP), a semi-empirical hindcast of wave parameters near the quickly developing accumulative Kelba Spit is presented for the period 1966-2006. The significant wave heights with a gross mean value of 0.56 m exhibited some quasiperiodic cycles, with the last high stage in 1980-95 and a decreasing overall trend of -0.001 m per year. At the same time, both the frequency and intensity of high wave events showed rising trends, and the mean wave heights during winter (December to February) increased as well. As the study area has the longest fetches in westerly directions, the discussed tendencies in wave conditions are sensitive to regional changes in the wind climate and can be related to a decrease in the local average wind speed on the one hand, but an intensification of westerly winds, storm events and the wintertime NAO index on the other. The roughest wave storms on record were associated with prominent W-storms on 2 November 1969 and 9 January 2005; a few other extreme wind events (e.g. in 1967, 1999, 2001), however, did not yield equally prominent waves.

Keywords: caged mussels, lysosomal membrane stability, micronucleus, Acetylcholinesterase, Algerian west coast

Received 16 November 2008, revised 19 January 2009, accepted 9 February 2009.

This work was partially supported through a grant from the Tassili Cooperation Research Programme (project 06 MDU 692: Biosurveillance de la pollution marine au niveau du littoral occidental algérien) with the collaboration of Dr J-C. Amiard (Service d'Ecotoxicologie, MMS (Mer, Molécules, Santé, Pôle Mer et Littoral, ISOMer, Université de Nantes, France).
An active biomonitoring study was carried out on the Algerian west coast using wild reference mussels (Mytilus galloprovincialis) sampled from the Kristel (K) site and transplanted in net cages during one month (between May and June 2007) to Oran Harbour (OH) and Mostaganem Harbour (MH), areas characterised by high levels of urban and industrial pollution. The biological response of the mussels was evaluated by their condition index and the use of a general stress biomarker (evaluation of lysosomal membrane stability: the neutral red retention time (NRRT) method), a genotoxic effects biomarker (determination of micronuclei (MN) frequency) and a neurotoxic effects biomarker (determination of the acetylcholinesterase (AChE) concentration).
      Compared to the K reference specimens, OH and MH caged mussels presented a significant decrease of NRRT in lysosomal haemocytes (56.45 ± 26.48 min and 67.25 ± 22.77 min, respectively) (78 ± 16.97 min for K mussels), an MN frequency respectively 7.3 and 9 times higher in the haemocytes and the gill cells of the OH caged mussels, and 7.2 and 6.4 times higher in the two tissues of the MH caged mussels. Significant inhibition of AChE activity was noted in the gills (16.93 ± 3.1 nmol min-1 mg prot-1) and the digestive gland (7.69 ± 1.79 nmol min-1 mg prot-1) of the OH mussels, but only in the gills (23.21 ± 5.94 nmol min-1 mg prot-1) of the MH mussels, compared to the organs of the K control specimens (35.9 ± 6.4 nmol min-1 mg prot-1 in the gills and 11.17 ± 0.49 nmol min-1 mg prot-1 in the digestive gland).
      This study reflects the interest in such in situ biomonitoring assays and the utility of these biomarkers for assessing the effects of pollution in the Algerian coastal marine environment.

Keywords: fluorescence, petroleum, seawater

Received 27 June 2008, revised 7 January 2009, accepted 28 January 2009.
The paper presents an improved method of determining petroleum pollutants in water based on fluorescence, which allows the oil content to be estimated with an accuracy better than 50%. The method was used to measure the oil content in Gulf of Gdańsk seawater sampled at Gdynia-Orłowo between January 2006 and September 2008. The 174 measurements made during this period ranged from 1 to 120 µg kg-1, but the majority did not exceed 20 µg kg-1. The most probable level of contamination is c. 5 µg kg-1.

Keywords: Red Sea, Jeddah coast, hard corals, Fungia spp., mycosporine-like amino acids

Received 7 July 2008, revised 4 February 2009, accepted 9 February 2009.
Mycosporine-like amino acids (MAAs) were studied in stony coral species (Fungiidae) along the Eastern coast of the Red Sea. Six species - Fungia scutaria, F. danai, F. corona, F. repanda, Ctenactis echinata and Lithophyllor lobata - were examined for MAAs at water depths of 5, 10, 15 and 20 m. Protein and chlorophyll were also determined and showed higher contents in winter than in summer. Generally, the total content of MAAs in summer was found to be approximately three times greater than in winter. Overall, concentrations of MAAs were greatest at a depth of 5 m. Porphyra-334 was the most abundant MAA in F. Scutaria and F. Danai, whereas asterina-330 was either not detectable (e.g. L. lobata) or present in low concentrations (e.g. F. danai, F. repanda and C. echinata). Shinorine was not detected in F. danai or L. lobata. Both C. echinata and L. Lobata had the lowest concentrations of MAAs, presumably because of their large calcareous skeletons. The variation in MAA concentrations among seasons and water depths is probably due to a number of factors, including the intensity of solar radiation, turbidity and phylogenetic variation.

Keywords: parasite, alien species, Southern Baltic

Received 8 August 2008, revised 16 December 2008, accepted 8 January 2009.
Alien species are now found all over the world. New fish parasites have been unintentionally introduced with infected alien fish imported for aquaculture or have sometimes spread with their intermediate invertebrate hosts transported in the ballast waters of ships. Four alien fish parasites have been recorded in Polish coastal lakes and lagoons, all parasitising eels. Three were introduced with the final host - the Japanese eel - introduced for aquaculture (Anguillicola crassus, Pseudodactylogyrus anguillae and Pseudodactylogyrus bini) and one (Paratenuisentis ambiguus) with its sole intermediate host (Gammarus tigrinus).

Received 25 August 2008, revised 9 January 2009, accepted 13 January 2009.

This work was conducted within the framework of the GLOBEC Germany project, with financial support from BMBF (03F0320C).
The abundance of the sardine in the North Sea suddenly increased after 1995. Since 2002, the sardine has been spawning regularly in the German Bight, and all its life stages can be found in the area. The larval feeding ecology of two small pelagic clupeiform species with very similar life histories was investigated, the particular aim being to determine signs of food overlap. The distribution and feeding of sprat and sardine larvae were investigated during late spring 2003 on two transects covering a wide range of environmental conditions in the German Bight. Larvae co-occurred at all the stations investigated. Sprat and sardine larvae shared a wide range of prey types. Gut fullness and feeding success were similar in both species; however, potential food competition is avoided to some extent by different habitat preferences.
