Vertical distribution of microbial communities in a perennially stratified Arctic lake with saline, anoxic bottom waters
Meromictic lakes are useful biogeochemical models because of their stratified chemical gradients and separation of redox reactions down the water column. Perennially ice-covered meromictic lakes are particularly stable, with long term constancy in their density profiles. Here we sampled Lake A, a deep meromictic lake at latitude 83°N in High Arctic Canada. Sampling was before (May) and after (A...
متن کاملFollow the light — diurnal and seasonal variations in vertical distribution of the mesopelagic fish Maurolicus muelleri
Previous 1 d studies (Giske et al. 1990, Sarsia 75:65–81; Baliño & Aksnes 1993, Mar Ecol Prog Ser 102:35–50; Rasmussen & Giske 1994, Mar Biol 120:649–664) of the mesopelagic fish Maurolicus muelleri have suggested that their vertical distribution changes as though they were following a constant light intensity, sometimes termed the ‘isolume’. Here we investigated whether such behaviour is consi...
متن کاملVertical distribution of fish larvae in the Canaries-African coastal transition zone, in summer
This study reports the vertical distribution of fish larvae during the 1999 summer upwelling season in the Canaries-African Coastal Transition Zone (the CanariesACTZ). The transition between the African coastal upwelling and the typical subtropical offshore conditions is a region of intense mesoscale activity that supports a larval fish population dominated by African neritic species. During th...

متن کاملA model of the vertical distribution of suspended sediment in the bottom layer of a natural water body
The paper suggests a stationary model of the vertical distribution of the concentration of suspended sediment in the bottom layer of a natural water body with a flat bottom. The model explains the concentration distribution, formed jointly by the settling of suspended particles and turbulent diffusion. The flow is assumed geostrophic above the bottom-influenced layer, while in the bottom layer ...
