In order to ensure more sustainable development of the coastal zone at the European level unified set of 27 socio-economic and environmental indicators have been recommended for the EU member states by the European Parliament and the Council in 2002. Following this idea, number of EU-funded projects related to the Integrated Coastal Zone Management with special focus on regional sustainable development have been initiated: SAIL - \"State of the Coast of the Southern North Sea\", DEDUCE \"Evaluation model for the sustainable development of European Coastal Zones\"; SDI-4-SEB - \"Sustainable Development Indicators for Integrated Coastal Zone Management of South-Eastern Baltic\". Last mentioned - SDI-4-SEB aims to promote the integrated way of trance-border coastal zone management in the South Eastern Baltic. The coasts of the Pomorskie Voivodship, Kaliningrad Oblast and Klaipeda County comprise unified coastal strip with identical geo-, morphological and dynamic features. This part of the Baltic coast typologically belongs to open sandy coast with similar problems of erosion, sand dynamics and economical development. Therefore environmental indicators - and among them especially geological - are of the high importance in the region.","PeriodicalId":6307,"journal":{"name":"2008 IEEE/OES US/EU-Baltic International Symposium","volume":"259 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2008-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77435435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Linking NPZD and foodweb models of an estuarine lagoon ecosystem","authors":"A. Erturk, A. Razinkovas, P. Zemlys, R. Pilkaitytė, Z. Gasiūnaitė","doi":"10.1109/BALTIC.2008.4625558","DOIUrl":"https://doi.org/10.1109/BALTIC.2008.4625558","url":null,"abstract":"Among aquatic ecosystems, estuarine lagoons are generally more complex than inland waters because of the combined effect of the land and the sea. These systems are under the influence of land through the rivers and have a restricted and temporally variable water exchange with the seas or the oceans. Estuarine lagoons are generally productive ecosystems which offer habitats for many species. Many coastal and estuarine lagoons are known to be important components of the natural capital providing opportunities for aquaculture. These ecosystems are difficult to analyze. Like most of the transitional waters, their trophic and ecological status cannot be defined easily because of their complexity. Most of them are usually under strong human influence or already modified heavily, which makes this task even more difficult. Nutrient phytoplankton zooplankton detritus (NPZD) models can help scientists to analyze the full picture of an aquatic system, together with physical, chemical and biological processes, to fill in the gaps of data between samplings and to forecast environmental changes and use this output for planning. Traditionally, these models have been developed and used by engineers extensively, usually with the aim of water resources and quality management. However, different needs may arise in ecological studies with different aims such as better understanding how an aquatic ecosystem works or analyze the interactions in an aquatic food web. In this case, different state variables may be needed than the conventional ones, which are used by more general water quality models that are available. In ecological studies, related to coastal lagoon ecosystems organism groups on the higher trophic levels can be of interest. In this study, an NPZD model and a trophic network model that contains organism groups on the higher trophic levels were linked using the ldquobottom-up controlrdquo approach. Such a linkage of models provides the possibility to use the advantages of both models; reproducing of the erratic behavior of nutrients and plankton as realistic as possible, while still taking the more complex organisms in the trophic network, which respond to external forcing in a larger time scale. The models developed in this study were applied to the Curonian Lagoon that is an important estuarine ecosystem for Lithuania.","PeriodicalId":6307,"journal":{"name":"2008 IEEE/OES US/EU-Baltic International Symposium","volume":"28 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2008-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88956574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 1992 FIMR started continuous measurements on board the ferry Finnjet, crossing the Baltic Sea Proper, using unattended recording and sampling system. During the spring of 2007 the ferrybox monitoring system was reinstalled in a new ferry Finnmaid providing real time observed data transmission with satellite connection. Chlorophyll-a (Chla) still remains the principal monitoring parameter. However, the distribution of cyanobacteria cannot be evaluated using Chla in vivo fluorescence, as most of their Chla is located in the poorly-fluorescing photosystem I. Instead, phycocyanin (PC) fluorescence is used in the detection of cyanobacterial blooms in 2005-07. PC fluorescence shows a linear relation to the biomass of the bloom forming filamentous cyanobacteria. During blooms of filamentous cyanobacteria the variability in Chla concentrations is better explained by PC fluorescence than by Chla fluorescence. Additionally, Chla records have been applied in validation of MODIS satellite monitoring for the water quality.","PeriodicalId":6307,"journal":{"name":"2008 IEEE/OES US/EU-Baltic International Symposium","volume":"35 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2008-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88536546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The vertical profiles of downwelling and scalar irradiance in the PAR region were measured in situ on the sea using a frame completed with two planar and a spherical PAR sensors. The measuring system allows calculate as the mean attenuation coefficients of a water column (Kd and Ko respectively) as well the depth profiles Kd(z) and Ko(z). These coefficients, e.g. optical density of the sea water, were varying from 0.13 m (Tallinn-Helsinki line, May) up to 0.75 m (Tallinn Bay, April). As an example some measurements’ series are shown in the figure 1. Fig.1. Variation of attenuation coefficients on Tallinn – Helsinki shipline in the spring 2007. It is seen, that the optical quality of water was much better in May compared to April 2007. Also, it is seen, that expecting the stations immediately near port and road, the Gulf of Finland was quite clear, especially in May. Some increase of optical density towards the Finnish coast could be mentioned also. Many of such cross-sections were made in the spring-summer period of 2007. For example a correlation between the water depth and optical density was followed on the shallows near Hiiumaa. US/EU-Baltic International Symposium 2008 Additionally the water transparency was estimated using the Secchi disk, profiles of chlorophyll were recorded with a fluorimeter, “spectrometric” attenuation coefficient spectra (c*λ), concentrations of chlorophyll a, suspended matter and yellow substance were determined from water samples in the laboratory. This study was supported by the Estonian Science Foundation (Grant No. 7000). The authors are thankful to Dr. Liis Sipelgas for the help with laboratory data.
