Última Моделирование возникновения и распространения гипоксии на мелководье 13 Васечкина, Е. Ф.; Ярин, В. Д.. Имитируется ситуация развития гипоксии в период весенне-летнего прогрева на мелководье. Исследуется пространственно-временная динамика процесса. Используется объектно-ориентированная модель планктонного сообщества пелагиали, дополненная гидрохимическим блоком, который описывает циклы азота и серы в аэробных и анаэробных условиях. Гидродинамика системы описывается интегральной двухслойной моделью, учитывающей влияние атмосферной изменчивости на развитие процесса. Моделируется реакция живых компонентов системы на смену режима в нижнем слое с окислительного на восстановительный и обратно.

Ano: 2006 URL: http://repository.ibss.org.ua/dspace/handle/99011/294 Cycles biogéochimiques du Fer et du Soufre dans les systèmes hydrothermaux en contexte sédimentaire du Bassin de Guaymas : traçages isotopiques et interactions micro-organismes/minéraux 5 Callac, Nolwenn. Active hydrothermal chimney and sediments of the Guaymas Basin (Mexico) host various microbial communities with different metabolisms, including those involved in biogeochemical cycles of sulfur and iron. It is established that, in these dynamic ecosystems, microbial activity depends on the availability of substrates in their environment and that prokaryotes could, in return locally affect the composition of the hydrothermal fluid and mineralogical composition of the chimney or sediment, by mediating the dissolution and / or precipitation of some mineral phases. In order to study these prokaryotes-biotope interactions, and establish links between the structure, the activity and the isotopic signatures of microbial communities with the physico-chemical...

A multiple year-round study of atmospheric dimethyl sulfide (DMS) (from December 1998 to April 2003) as well as sulfur-derived aerosols (methanesulfonic acid (MSA) and non-sea-salt sulfate) (from March 1991 to February 2003) was conducted at Dumont d'Urville, coastal Antarctica. The three sulfur-derived species exhibit a seasonal cycle characterized by maxima in midsummer (January). Whereas the interannual variability of winter levels remains low, a strong interannual variability is shown in summer, particularly for DMS and MSA, and to a lesser extent for non-sea-salt sulfate. Over the 1998-2003 time period, January 2002 stands out with high values for all sulfur species. These interannual variabilities of atmospheric summer levels are examined in the...
