Excitation of an extreme wave by standing current

Pavlo Anakhov

Oceanologia > 2023 > Vol. 65 (4) > 564--570

The statistics suggest that extreme waves cause more damage in shallow waters and at the coast than in the deep sea. In the linear theory of the formation of extreme waves, their existence is interpreted as a local superposition of surface monochromatic waves. The event of excitation of extreme waves can be understood as an increase in natural oscillations of the water basin. The conditions for the...

Modified logarithmic distribution of wind-driven flow velocity in remote foreshore of the non-tidal sea

Rafał Ostrowski, Magdalena Stella-Bogusz

Oceanologia > 2023 > Vol. 65 (4) > 556--563

The paper presents the results of the novel modelling of the wind-driven current in the southern Baltic Sea. The steady current is accompanied by wave-induced orbital velocities. The bed boundary layer related to wave-induced oscillatory flow gives rise to the appearance of additional shear stresses affecting the wind-driven current. This impact included in the wind-driven current model yields a modified...

Fatima Zohra Bouthir, Imane Afandi, Sophia Talba, Maylis Labonne, more

Oceanologia > 2023 > Vol. 65 (4) > 612--623

The Moroccan Southern Atlantic coast is mainly influenced by upwelling, Saharan dust and anthropogenic micropollutant input. These factors contribute to increasing the availability of metal elements in waters. To differentiate human impact from natural variability, knowledge of background concentrations of metals and their fluctuations in bioindicator organisms such as zooplankton is important. This...

Oceanologia > 2023 > Vol. 65 (4) > 548--555

Oceanic internal waves are an active ocean phenomenon that can be observed, and their relevant characteristics can be acquired using synthetic aperture radar (SAR). The locations of oceanic internal waves must be determined first to obtain the important parameters of oceanic internal waves from SAR images. An oceanic internal wave segmentation method with integrated light and dark stripes was described...

Edyta Sierka, Michał Bujok, Barbara Stalmachova, Tomasz Horaczek

Journal of Water and Land Development > 2022 > Special Issue > 164--170

The increasing salinity of water in reservoirs is caused by climate change. On the other hand, an increase in salinity promotes the group species, halophytes that tolerate or need NaCl for growth. The aim of this study was to identify the response of facultative halophytes’ photosynthetic apparatus efficiency (PE) to water salinity. The study covered the spiny water nymph (Najas marina L.) population...

Sustainable development, Agenda 2030 and food security in historical perspective

Wiktor Szydło

Ekonomia i Środowisko > 2023 > nr 2 > 154--174

Koncepcja zrównoważonego rozwoju zyskała na rozgłosie w ostatnich dekadach. Równocześnie, neoliberalizm (główny nurt w wymiarze społeczno-ekonomicznym w państwach kapi-talistycznych od połowy lat 70. XX wieku) jest pojęciem znacznie mniej popularnym w debacie publicz-nej. Artykuł stanowi próbę odpowiedzi na pytanie, czy paradygmat zrównoważonego rozwoju i jego najnowsza odsłona (Agenda 2030) zdecydowanie...
