Despite growing research on microplastic contamination in beach environments, the factors influencing pollution distribution remain poorly understood. This study aims to bridge this knowledge gap by investigating across 11 Latvian marine beaches (northeastern Europe). The area experiences a four-season climate and is influenced Gulf of Riga Baltic Sea. Beaches were selected based prior (Dimante-Deimantovica et al., 2023), data collection took place from autumn 2022 summer 2023.Microplastic...
Available CTD profiles from the Gulf of Riga (May–August, 1993–2012) were analyzed to study inter-annual and long-term changes in temperature, salinity density relation river runoff atmospheric forcing (e.g. Baltic Sea Index). To describe temporal vertical stratification, upper mixed layer (UML) deep (DL) parameters estimated. On average UML depth increases 8.7 m May 9.0, 11.5 13.7 June, July August, respectively, temperature 8.0°C 12.5, 18.7 18.6°C (May, August) while 4.90 g kg−1 5.14, 5.28...
Abstract. The Gulf of Riga is a relatively shallow bay connected to the deeper central Baltic Sea (Baltic Proper) via straits with sills. decrease in near-bottom oxygen levels from spring autumn common feature gulf, but 2018, extensive hypoxia was observed. We analyzed temperature, salinity, oxygen, and nutrient data collected along historical available environmental databases. Meteorological hydrological study year were compared their long-term means variability. suggest that pronounced...
Abstract. Satellite remote sensing imagery and numerical modelling were used for the study of river bulge evolution dynamics in a non-tidal sea, Gulf Riga (GoR) Baltic Sea. Total suspended matter (TSM) images showed clearly formed anti-cyclonically rotating from Daugava River discharge during studied low wind period. In about 7–8 days grew up to 20 km diameter, before being diluted. A high-resolution (horizontal grid step 125 m) General Estuarine Transport Model (GETM) was detailed...
Thermohaline structure in the Gulf of Riga (GoR) was investigated by a multi-platform measurement campaign summer 2015. Stratification water column mainly controlled temperature while salinity had only minor contribution. Buoyant maxima with variable strength were observed intermediate layer Riga. The likely formed simultaneous upwelling–downwelling event at two opposite sides Irbe strait. inflowing salty did not reach deeper (> 35 m) parts gulf and, therefore, near-bottom remained isolated...
We present a comprehensive assessment of micro- and mesoplastic pollution along 24 beaches the Latvian coastline (Northern Europe, Baltic states) establishing baseline for distribution in Sea Region. A detailed analysis sand granulometry, hydrodynamic variables (waves currents) tourism intensity allowed us to understand better factors that drive plastic beaches. Over 250 volunteers participated sample collection highlighting importance citizen science as tool support data collection. Our...
Development of smart city concept is challenging for every city. Smart approach consists several components and one them traffic. Parking the traffic components. Due to rapid growth vehicles on streets, finding an available parking space becoming a big obstacle in modern life. For cities with large number residents or places where sports artistic events take place, search free lot major problem can be frustrating experience. management system affects improves people's daily life experience...
Microplastic pollution has become widespread, occurring even in areas with low anthropogenic impacts, small human populations, and tourism intensity. Marine beach sand represents the interface between inland marine environments acts like a fingerprint of all processes happening within onshore catchment sea, driven by hydrodynamic processes. An extensive dataset is required from different coastal ecosystems to understand microplastic pollution. Here, we set baseline for micro- mesoplastic...
Over the past decades, changes in light conditions of coastal waters, induced by darkening due to water browning, has been gaining momentum within scientific community. Although there is a general agreement that caused shifts climatic conditions, actual links between trends attenuation browning and drivers are still being debated, as causality relationships often assessed through use indirect evidence. In this study, we employed algorithmically processed remote-sensing modelled data with...
Abstract. An array of moored current meters and gliders were deployed across the Central Baltic Sea. Weak low persistent currents driven by wind-driven Ekman transport observed in upper layer offshore area. Stronger with higher persistency near coast, presumably local sea level gradient. The kinetic energy was largely to be low-frequency band (timescales >36 h), but on shorter timescales areas, where halocline close seafloor. A strong highly gravity bottom Fårö sill. Circulation pattern,...
Upwellings are characteristic for the Baltic Sea region including Gulf of Riga, although current knowledge is rather limited with only few research conducted in itself. Upwelling events Riga 2010–2022 were studied by analyzing sea surface temperature time series from coastal stations and SmartBuoy, together satellite data, model CTD (conductivity, temperature, depth) surveys. The starting/end point, active, relaxation phases defined each event to describe characteristics length phase. less...
Abstract. The Gulf of Riga is a relatively shallow bay connected to the deeper central Baltic Sea (Baltic Proper) via straits with sills. decrease in near-bottom oxygen levels from spring autumn common feature gulf, but 2018, hypoxia was exceptional. We analyzed temperature, salinity, oxygen, and nutrient data collected 2018 historical available environmental databases. Forcing study year were compared their long-term means variability. exceptional due occasionally dominating north-easterly...
Abstract. Satellite remote sensing imagery and numerical modelling were used for the study of river bulge evolution dynamics in a non-tidal sea, Gulf Riga (GoR) Baltic Sea. Total suspended matter (TSM) images showed clearly formed anti-cyclonically rotating from Daugava River discharge during studied low wind period. In about 7–8 days grew up to 20 km diameter, before being diluted. Bulge growth rate was estimated as rb ~ t 0.31± 0.23 (R2 = 0.87). A high resolution (horizontal grid step 125...
A regional, 0.5 n.m. and 20 sigma layer grid model of the Gulf Riga (GoR) was implemented based on Princeton Ocean Model code with initial conditions atmospheric forcing taken from HIROMB HIRLAM output. basic run that covers an ice-free period May 1-December 31, 2012, brought following results: - mean summertime surface circulation in GoR displays a whole-basin anticyclonic gyre more intense currents western half gyre; two seasonal are identified: Northern Longshore Current (NLC) part...
